    专利说明:

    The invention relates to a colored adhesive tape, in particular a yellow, orange or black adhesive strip. The invention relates to a colored adhesive strip which is resistant to high temperatures and to flames, and to the use of a support for its manufacture. , preferably a cable winding band, having a temperature class of at least T3 according to LV 312, provided with a textile support, comprising at least one polymeric synthetic material, to which is applied, on at least one side, one layer of adhesive. In addition, the invention relates to the use of a support for the manufacture of such an adhesive tape and a bundle of cables having such an adhesive tape.
    For bundling and for the protection of conductors, for example in the automotive field, these are often provided with protective sheaths. Hoses, tubes and advantageously cable winding strips are used here.
    The adhesive tapes, also those of the type mentioned, must satisfy, with regard to their properties of use, to unique standards, in particular to the standard LV 312 (10/2009). This standard classifies adhesive tapes with regard to their properties for use in the automotive industry, preferably for bundling and winding conductors and conductor sets. The mentioned standard was developed by car manufacturers AUDI AG, BMW AG, Daimler AG, Porsche AG and Volkswagen AG.
    When in the following, this standard LV 312 or other standards, to which reference is made for example in standard LV 312, are mentioned, such as for example the standards EN 1942, EN 14410, DIN EN 1939, always editions in force at the time of the request.
    In summary, these are the following editions: LV312 10-2009, DIN EN 1942 06-2008, DIN EN 14410 06-2003, DIN EN 1939 12-2003, ISO 3795 10-1989, DIN 55943 10-2001, DIN ISO 18451 07-2014, DIN ISO 6722 10-2011, EN 2286-2 07-1998 and DIN EN ISO 9237 12-1995.
    Among the properties of use of adhesive tapes are, for example, the adhesiveness on the back of the tape and the unwinding force as well as the tearing ability by hand. Other properties of use are adhesiveness to specific materials, thickness, tear elongation, tensile strength, resistance to tear propagation, flagging (lifting of the ends) as well as as resistance to abrasion, temperature resistance and flame resistance.
    For increased resistance to abrasion, preferably in the adhesive strips fabrics or combinations of fabrics and nonwoven materials are used. For example, fabrics based on polyester or polyamide are customary. This results in high resistance to abrasion. Due to the composition of the fabric, however, the field of use is limited to long-term loading temperatures of up to 150 ° C. Similarly, in a flame resistance test according to LV 312 / ISO 3795, the highest fire class A is not reached. For higher temperature requirements, therefore, adhesive tapes having glass fabric supports are used. These can be used without problem up to 250 ° C, generally comply with fire class A according to LV 312 / ISO 3795, but have practically no resistance to abrasion and therefore do not deploy at all. desired protective effect.
    For most use cases, cable winding strips are stained black with dyes, such as pigments. The document EP 1 607 459 B1 deals in detail with the problem of the stable maintenance of this dye at high temperature stresses. Particularly suitable dyestuffs are soot, which is introduced into the fibers and yarns of the support fabric by mass dyeing.
    Mainly for use in electric vehicles, the high voltage conductors and in particular also the adhesive strips used to wrap these conductors are made with signaling colors, for example in yellow or orange. For security reasons, it is necessary that these colors are still detectable even after a stress at high temperatures. Some color change is generally accepted, but not fading or browning.
    An adhesive tape of the type mentioned in the introduction is described in EP 2 546 317 B1. It consists of a textile support and an adhesive layer applied to at least one face of the support, the support being colored by a mixture of dyes and / or pigments. The mixture is constituted by dyes and / or yellow and red pigments, the yellow dye and / or the yellow pigment being based on anthraquinone and the red dye and / or the red pigment consisting of an azo-type compound or comprising a mixture of anthraquinone compounds and azo compounds.
    As far as the distinction between dyes and pigments is concerned, we refer to DIN 55943: 2001-10 or also to DIN ISO 18451-1: 2014-07 (unchanged in this context), according to which all the coloring substances are called dyes. These are then divided into soluble and insoluble pigments.
    The problems of producing adhesive tapes with signal colors with the support materials used in a known manner, also for high temperature classes, are discussed in EP 2 546 317 B1. It is emphasized that with "orange pigments standard with azo base bodies, the use of which for the orange coloring of a textile tape backing seems to be the most obvious technical solution, only a low temperature class could be achieved, both of dyeing in room than during dyeing in the mass. A higher temperature stability according to the T3 class (150 ° C.) is then achieved according to the patent by a mixture of an azo pigment and an anthraquinone pigment.
    However, bulk dyeing - for example, according to EP 1 607 459 B1 for soot as a colorant - in the case of colored fabrics is strongly discouraged, since colored pigments / dyes thus introduced into a support show degeneration phenomena, that is to say a discoloration. Instead, dyeing of the fibers, filaments or yarns of the textile support takes place according to EP 2 546 317 B1 by dispersion dyeing. When dyeing in dispersion, synthetic dyes which are hardly soluble or practically insoluble in water are used. Since dyeing is however also carried out from an aqueous medium, the dyes are ground very finely and introduced into a dye bath heated to about 100 ° C. The finely distributed dye particles therein rise from the bath and then diffuse into the fibers where they become detached and must participate in a strong bond.
    When continuously dispersing dyeing (for example in the thermosol process with a built-in scarf) or discontinuously (so-called bundle dyeing or using a "high pressure jigger"), white fabric is loaded by coloring in a soaking bath. Dispersants are used here as adjuvants, in order to obtain a regular distribution of the dyes in the dispersion. In this dyeing process, the dye is first placed around the fibers and then penetrated into them under the influence of heat and / or pressure. In preparation for the dyeing process, to facilitate penetration, desizing or removal of oils and / or prefixing of the fabric may take place. During continuous dyeing in the thermosol process, a thermal fixation process of the dye is arranged downstream.
    Disadvantageously, anthraquinone, as it is to be used according to EP 2 546 317 B1, is classified as a substance dangerous to health. The substance is considered to be potentially carcinogenic and is therefore suspected of causing cancer.
    The problem underlying the invention relates to the improvement of a colored adhesive tape of the type mentioned in the introduction while retaining the advantageous use properties. In particular, it is intended for this to provide an adhesive tape having improved temperature and flame stability, which preferably has a high abrasion resistance. If possible, the use of substances dangerous to health, such as anthraquinone, should also be avoided. The color of the adhesive tape will be in particular yellow, orange or black.
    This problem is solved according to the invention in that the color of at least a portion of the textile support is formed by the clean color of the synthetic polymeric material.
    It may also be provided in addition or alternatively according to the invention that the synthetic polymeric material of the textile support is an aromatic polymer, containing nitrogen of the group of polyoxadiazoles (POD), or at least one comprises.
    Therefore, the use of dyes, such as soot, azo pigments or anthraquinone or others, for the dyeing of the support can be advantageously dispensed with completely. Since the color is formed by the synthetic polymeric material of the textile backing, the whole problem of finding a suitable dyeing process is also advantageously eliminated.
    According to the invention, it is possible to use, in particular as synthetic polymeric material, a textile support for the manufacture of the adhesive strip, an aromatic polymer, containing nitrogen, which comes from the group of polyoxadiazoles (POD) and polybenzobisoxazoles (PBO). or polybenzimidazoles (PBI). The many conjugated double bonds present in these synthetic polymeric materials form a chromophore system so large that the textile backing material appears to be colored without the use of other pigments or dyes.
    In addition - especially by copolymerization - color-enhancing functional groups, which cause a shift of color to the desired shade, can be introduced into the polymeric structure of the synthetic material. By mesomeric and inductive effects of auxochromic groups, such as for example the -OH, -NH 2, -NHR, -NR 2 or -OR groups (with R as an aliphatic or aromatic radical), a delocalization of an electronic system called π, formed in the conjugate double bonds of the chromophores is enhanced and a bathochromic displacement occurs, also called redshift. By shifting the absorption spectrum of the UV range into the visible range of the longer wavelengths, which are lower in energy, of the electromagnetic spectrum, previously transparent polymers to the human eye can become colored and optically perceptible. .
    Without using, for example, red and yellow dyes, the entire set of orange shades according to the RAL system can be adjusted according to the invention as required: RAL 2000 orange yellow, RAL 2001 orange red, RAL 2002 orange blood , RAL 2003 pastel orange, RAL 2004 pure orange, RAL 2005 bright orange, RAL 2007 bright orange, RAL 2008 orange light red, RAL 2009 orange signaling, RAL 2010 orange safety, RAL 2011 dark orange, RAL 2012 orange salmon, RAL 2013 orange-pearly.
    RAL colors are colors that are standardized according to a color catalog. The name RAL is derived from "Reichs-Ausschuss fur Lieferbedingungen" (Imperial Committee for Delivery Conditions), which was founded in 1925 in Berlin and was used to rationalize the German economy. Each color in the color catalog is associated with a four-position color number. The purpose of standardization of grades is that customers and suppliers no longer have to exchange color samples on material defined for mutual understanding, but only one RAL number. RAL colors can also be viewed on the Internet under the link https://de.wikipedia.org/wiki/RAL-Farbe.
    Preferably, it is possible to obtain, according to the invention in particular, a pastel-orange RAL-2003 color or also non-standardized intermediate shades in the support of the adhesive strip. It is also possible advantageously according to the invention, in a simple way, to select specific shades in the support of the adhesive strip, in the series of colors RAL 1000 (yellow), in the series of colors RAL 3000 (red) and in the RAL 8000 color series (brown) as well as black.
    Another possibility is to characterize the shades by what is known as the "Pantone Matching System (PMS)". PMS, just like the RAL system, is the name of a color system also widely used internationally, which is mainly used in the graphic and printing industry. It was developed in 1963 by Pantone LLC, a US-based US company headquartered in Carlstadt, New Jersey. The Pantone Matching System is based on 14 basic colors which, when mixed with each other in different color ratios, give all the other colors represented in the system. The colors are printed on at least three different types of paper, namely coated paper, uncoated paper and matte paper, to represent the color printing of Pantone colors also defined by a numerical code according to the printed medium. Thus, each color print can vary in part considerably depending on the surface nature of a paper. For this reason, the colors according to Pantone are defined by the numerical code and - when printed on paper - also by the corresponding letter for the type of paper used (C = coated, U = uncoated, M = matte). The preferred shade in the context of the RAL 2003 orange-pastel invention corresponds in the PMS system to the grade 1575. Moreover, there are particular and basic colors in the Pantone Matching System, which do not carry numerical references but names. Pantone colors are used, for example, to define colors for flags, for example, in the European flag, blue for the shade "Pantone Reflex Blue" and the yellow of the twelve stars for the shade "Pantone Yellow".
    To increase UV resistance, polymers, fibers or yarns may be provided with additional stabilizers. Polyoxadiazole fibers or yarns may be provided with stabilizers, for example the potassium or sodium salts of m-azobenzenedicarboxylic or p-azobenzenedicarboxylic acids.
    An advantage of the invention is that, thanks to the use according to the invention of colored polymeric supports, however free of dyes, there are no colored constituents in the adhesive strip which can reduce the compatibility of the strip. adhesive according to the invention with a conductor material. Thus, subsequently, during storage or solicitation of the adhesive tape by increased temperatures, it can not occur either discoloration of the textile material, or migration of the dye. All of the factors, such as a necessary excess of dye and the use of small soluble coloring molecules as well as color accelerators in the context of dispersion dyes, such as a possibly disadvantageous effect of the irradiation by UV of the adhesive coating applied to the support, such as the plasticizer acting as appropriate in the case of soluble dyes as a solvent, which disadvantageously promote an increased migration of dyes out of the polymer of a conductor insulation, which is enveloped by the adhesive tape according to the invention, or such as the chemical degradation of the insulation of the driver itself, can therefore be successfully countered by the invention. The invention instead enables the manufacture of corresponding cable bundles having a stable colored adhesive strip and also a stable color conductor sheath. The electrical conductors and the other cable gland components are distributed in a known manner in the automotive industry, for setting their maximum temperature of long-term use, in temperature classes, which are shown in Table 1. In depending on the field of use in the automotive industry, it is advantageous to use an adhesive tape according to the invention when the latter or a bundle of cables wrapped by the adhesive tape must have a resistance up to temperatures of more than 125 ° C, that is to say when it is used under conditions of at least one temperature class T3 (C), preferably also a temperature class T4 (D) or T5 (E) according to LV 312.
    Table 1: Distribution of temperature classes according to LV 312
    In addition, the invention allows the manufacture of stable colored adhesive tapes having the highest fire class according to Table 2 below.
    According to LV 312, a minimum flame resistance of a set of conductors will ensure that the spread of a fire is prevented, at least not favored. In a corresponding test, therefore, the adhesive tape is tested in association with defined conductors. The test is carried out according to the ISO 3795 and FMVSS 302 standards, sets of conductors wound with a covering of 50%, consisting of seven conductors having a defined section and a defined material, being tested.
    Table 2: Class distribution according to flame resistance according to LV 312
    Depending on the result of the test, a division into classes is carried out as shown in Table 2. Adhesive strips according to the invention advantageously achieve the requirement of fire classes A and B.
    The son in the support of an adhesive tape according to the invention may consist of staple fiber yarns as well as continuous yarns. Continuous yarn fabrics have higher abrasion resistance compared to discontinuous yarn fabrics.
    With regard to the strength of the fibers and therefore the abrasion resistance of the textile supports made from them, it is advantageous for the supports according to the invention that a degradation of the fibers - since they are stained with prior to the material - can not occur as for example when dyeing in dispersion in a dye bath.
    For example, the fabric according to the invention, in the case of nominally identical fabrics with regard to the fineness of the yarns and the number of yarns, has a higher resistance to abrasion because subsequent degradation of the yarns by a treatment of dyeing is completely excluded.
    In a particularly preferred manner, part of the fibers or all the fibers may be partially or completely constituted by the colored polymer material according to the invention. The yarn used for the manufacture of the fabric may in particular be constituted according to the invention exclusively by polyoxadiazole (POD), polybenzobisoxazole (PBO) or polybenzimidazole (PBI), but also by a mixture of these polymers and / or by a copolymer of POD, PBO or PBI.
    In other embodiments, the yarn may contain fibers of another textile material or the fabric may contain yarns of other textile materials that do not come from the aforementioned groups. These fibers or threads may for example be constituted by a synthetic or natural polymer, in particular by a polyamide (PA), a polyester (PES), in particular a poly (ethylene terephthalate) (PET), an aramid (m aramid or p-aramid), such as poly (p-phenyleneterephthalamide) (PPTA) or poly (m-phenyleneterephthalamide) (PMPI), cellulose, polyvinyl alcohol (PVAL), polyacetate vinyl acetate) (PVAC), polyetheretherketone (PEEK), polyphenylene (PPP), polyphenylene oxide (PPO), polyphenylene sulfide (PPS), polyphenylenether (PPE), combinations of aforementioned materials are also possible. As a result, increases in strength and other increases in temperature and flame resistance are possible.
    For example, polyester fibers are advantageous because they have low density, high viscosity and high tear elongation, very good dielectric behavior, low water absorption and low wear. In particular - although polybutylene terephthalate (PBT) may also be used - it is possible that some of the proportionately present polyester fibers or all the proportionately present polyester fibers may be wholly or partly poly (ethylene terephthalate) (PET).
    The proportion by amount of POD, PBO, PBI and / or the corresponding copolymers in the hybrid textile system may be from 50 to 100% by weight, in particular from 55 to 80% by weight.
    In addition, the yarn may contain fibers of a non-textile material or the fabric may contain non-textile yarns of these fibers.
    It may for example be here metal fibers, carbon fibers, glass fibers or basalt fibers, combinations of these fibers or son with each other or with other materials being also possible .
    By the combination with a suitable self-adhesive, it is possible to produce adhesive tapes which desirably combine good abrasion resistance with high temperature and fire resistance. Silicone self-adhesives are particularly suitable as temperature-resistant self-adhesive.
    The abrasion resistance is determined according to the LV 312 standard based on DIN ISO 6722, in that the adhesive tape is first bonded to a pin (metal rod) with a diameter of 5 mm. Using a scraper tool, which has a needle diameter of 0.45 mm, the number of strokes required to tear the adhesive strip is then determined under a weight of 7 N. With respect to abrasion resistance, the classification shown in Table 3 below is provided in LV 312.
    Table 3: Distribution of abrasion classes according to LV 312
    In particular, the adhesive strip may have at least one abrasion of class C according to LV 312 (10/2009). This means that the adhesive tape advantageously withstands at least 700 up to 800 strokes before it is worn. In some examples among those still described in the following, we even reach class D.
    The good abrasion resistance of an adhesive tape is advantageous for fields of use in which the adhesive tape is subjected to high mechanical stress. For a further increase in wear resistance, combinations of fabrics may preferably be used with nonwoven materials, either the fabric or the nonwoven being colored according to the invention.
    Tissues that can be used according to the invention, preferably as supports, are known per se. For example, Zylon® fabrics are used with PBO fibers for ballistic protection vests and fabrics with PBI fibers for fire fighting jackets. Fabrics with POD fibers are used, under the Arselon® brand, for high temperature filters in metallurgy, cement processing and asphalt manufacturing. For this purpose, relatively thick and heavy fabrics are generally used, since for these uses properties such as tear resistance, rigidity or insulating power are important. For use in the field of adhesive tapes, particularly in the field of cable winding belts, these fabrics can not be used in unchanged form. Their high weight would oppose the general desire for weight reduction for automobiles, their large thickness would be disadvantageous in tight mounting spaces and their coarse fabric structure is opposed to abrasion requirements.
    According to the invention, it is in the preferred place for the textile support to comprise a fabric which, in particular, has a plain weave, the number of warp and weft yarns being in particular in each case greater than 20 per cm and preferably at least 25 per warp and / or weft. The thickness of the yarns will in particular be less than 600 dtex and preferably in the range of 200 dtex to 400 dtex. As the upper limit for the number of warp and weft threads, 80 per cm, preferably 60 per cm, and particularly preferably 45 per cm, will be considered. The invention is explained in more detail using exemplary embodiments shown in the drawing. In these figures:

    In the various drawing figures, identical parts are always provided with the same references, so that they are generally only described once.
    With regard to the subsequent description, it is claimed that the invention is not limited to the exemplary embodiment and therefore not to all or several characteristics of the combinations of features described, on the contrary, each partial characteristic of the invention. Embodiment is significant in itself for the purpose of the invention, even separately from all the other partial features described in association therewith. For example, the characteristics of the media and tape properties shown in the different lines in Tables 4 and 5 below are not necessarily related.
    In particular, an autonomous inventive significance is attributed to the use of a textile support whose polymeric synthetic material is an aromatic polymer, containing nitrogen, preferably of the group formed by polyoxadiazoles (POD) or also of the group formed by polybenzobisoxazoles (PBO) or polybenzimidazoles (PBI), for the manufacture of wrapping means for an elongate product, in particular of the adhesive tape according to the invention.
    As first shown in Figure 1, which shows a preferred use case of an adhesive tape 1 according to the invention for winding cable sets, that is to say a winding tape of cables, an adhesive tape according to the invention is advantageously suitable for wrapping wires 2 of electrical conductors, which allows to manufacture - in the case represented by a helical winding - a bundle of cables 3, in particular for the automotive industry.
    The adhesive tape 1 according to the invention comprises a strip-shaped colored textile support 4 and an adhesive layer 5 applied to the support 4, preferably constituted by a pressure-sensitive self-adhesive. The textile support 4 comprises at least one polymeric synthetic material, the color of the support 4 being formed, preferably completely, but at least in part, by the inherent color of the polymeric synthetic material.
    The adhesive tape 1 according to the invention combines a high abrasion resistance, as is known from cable winding belts made from polyester fabrics, with high resistance to temperature and flame, the adhesive strip 1 being preferably made in the colors yellow, orange or black and the synthetic polymer material of the support 4 being a textile, in particular a fabric based on an aromatic polymer containing nitrogen of the group formed by the polybenzobisoxazoles (PBO), polybenzimidazoles (PBI) or polyoxadiazoles (POD).
    As an example for polybenzobisoxazoles (PBOs), there is shown in FIG. 2 a general structure formula of poly (2,6-benzobisoxazole), which represents a synthetic material preferably used as support material 4 in the context of the invention. Polybenzobisoxazoles (PBOs), which contain aliphatic or alicyclic groups between the different benzobisoxazole groups, are largely colorless. On the other hand, when using a poly (p-phenylene-2,6-benzobisoxazole) fabric - Zylon® brand name - shown in FIG. 3, by the numerous conjugated double bonds, a system is formed. chromophore of such a size as to obtain, without the addition of other pigments or dyes, a yellow color as an inherent property, stable at the temperature. By the preparation of suitable copolymers, as mentioned above, further color shift in the longer wavelength region is possible.
    FIG. 4 shows a general chemical equation for a polycondensation reaction of tetraaminobiphenyl (left) and isophthalic acid (right) with dissociation of water for the preparation of polybenzimidazole (PBI), which is also a synthetic material preferably usable as support material 4 in the context of the invention. Because of its extended chromophore system, without the addition of other pigments or dyes, polybenzimidazole (PB1) has a desired yellow-brown color for many uses in the automotive field.
    Finally, FIG. 5 shows, as another example for a support material 4, which represents a synthetic material which can preferably be used, a polyoxadiazole (POD) general structure formula. Polyoxadiazoles (PODs), which contain aliphatic or alicyclic groups between the different oxadiazole groups, are largely colorless. On the other hand, when using a poly-1,4-phenylene-1,3,4-oxadiazole fabric, as shown in FIG. 6 - Arselon® brand name - by the numerous conjugated double bonds, it is a chromophore system is formed of a size such that the fabric obtains, without addition of other pigments or dyes, already a yellow color. If the base polymers are copolymerized with 0.5-5% by weight (based on the base polymer), preferably with 1-3% by weight (based on the base polymer), of the formula of poly-4,4'-azobenzene-1,3,4-oxadiazole structure shown in Figure 7, Arselon® S brand name or poly-3,3'-azobenzene-1,3,4-oxadiazole, obtains, by the azo group, a bathochromic displacement up to a desired orange shade, preferably RAL 2003. The desired yellow or orange color is in all these cases an inherent property of the material, stable at the temperature, so that no additional staining with color-sensitive pigments or pigments is required.
    However, where appropriate, in the context of the use according to the invention in particular of colorless or also colored polyoxadiazole (POD), provision may be made for coloring or a color change with dyes or dyes. pigments. For example, colorless or orange-colored POD fibers or fabrics may, if necessary, be colored by dyes or black pigments, such as, for example, soot, without thereby favorably increasing the temperature stability, Advantageously high resistances to flame and abrasion are lost. Dye dispersion or in the mass with colored pigments can take place. When colorants are used as dyestuff, depending on the dye solubility properties, the dyeing may be carried out in an aqueous solvent or in an organic solvent, such as an alcohol, a ketone or an oil, or in appropriate mixtures. Basic or acid solutions can be used. In addition, it is possible to use coloring accelerators, called carriers, where appropriate together with surfactants, which cause swelling of the fibrous material and which can thus facilitate the diffusion of dyes. Particularly suitable color accelerators are aromatic compounds, such as, for example, phenol, phenylphenol, salicylic acid including its derivatives or xylenes. It should be noted, however, that the nitrogen-containing aromatic polymers of the group consisting of polyoxadiazoles (POD), polybenzobisoxazoles (PBO) or polybenzimidazoles (PBI) represent groups of substances whose dyeing is difficult. A carrier which contains N-cyclohexyl-2-pyrrolidone can advantageously be used. A mixture of N-cyclohexyl-2-pyrrolidone with an alkyl or aryl benzoate, particularly with methyl benzoate, is preferred, the mixture being usable in solution or suspension form. A preferred mass ratio of N-cyclohexyl-2-pyrrolidone to alkyl or aryl benzoate may be in the range of 2: 3 to 8: 1.
    Table 4 gives an overview of the fabrics that can be used as polymeric synthetic materials of support 4 for the production of adhesive strips 1 according to the invention and of their properties.
    Table 4 shows that the number of warp threads of a preferred fabric for support 4 can vary in the range of 8 per cm to 42 per cm. The numbers of yarns in the weft may vary in the range of 6 per cm to 30 per cm. The thickness of the yarns of the warp as well as the weft can preferably each time be in the range of 250 dtex to 2800 dtex.
    Table 4: Structure of the fabric and description of the fibers
    * in a different way compared to the ISO 9237 standard, we work with a pressure difference of 500 Pa
    For the yarns of the support 4, the fibers are preferably mainly converted into continuous yarns. These continuous yarn fabrics have higher abrasion resistance than fabrics with staple yarns. Dense weaving with twill weave and or canvas is advantageous.
    The filament numbers of a continuous yarn may be, as also shown in Table 4, preferably in the range of 200 to 1800. The fineness of the fibers of the filaments may preferably be in a range from 2 dtex to 3 dtex. This applies - independently of each other - to both the warp and the weft. The thickness of the warp yarns with respect to the width may advantageously be in the range of 6000 dtex / cm to 25,000 dtex / cm. The thickness of the weft yarns with respect to the length can advantageously be in the range of 4000 dtex / cm to 17,000 dtex / cm. The specific gravity with respect to the surface ("surface weight") can be in the range from 200 g / m2 to 450 g / m2. The thickness may preferably be in the range of 0.20 mm to 0.65 mm, preferably in the range of 0.25 mm to 0.30 mm.
    As self-adhesive, temperature-sensitive, pressure-sensitive for the adhesive layer 5 - as already mentioned - silicone-based self-adhesives are particularly suitable. Surprisingly, however, it is also possible to obtain good results with adhesives based on polyacrylates or synthetic rubber. During a solicitation by an extreme temperature there then occurs certainly here a hardening of the mass of adhesive; the protective winding applied in a helical manner with a covering around the wires 2 of the cable set 3 resists however thanks to the good adhesion on the back of the strip to the test of flexion prescribed after such an aging test according to the LV 312 standard. Basically, the use of acrylates in solution or also the use of acrylate-based monomer mixtures or acrylate-based prepolymers is also possible. After coating, they are optionally thermally polymerized or UV radiation and crosslinked.
    The adhesive layer 5 may have an applied weight (specific basis weight) in the range from 60 g / m 2 to 200 g / m 2, preferably a weight applied in the range from 90 g / m 2 to 150 g / m 2, particularly preferably up to 100 g / m2.
    Table 5: Overview of adhesive tapes
    Table 5 lists various adhesive strips 1 according to the invention with their properties compared to existing adhesive tapes. For the adhesive strips 1 according to the invention indicated in this table, these are the following:
    Example 1: Support 4 made of staple fiber fabric of a poly-1,4-phenylene-1,3,4-oxadiazole copolymer and of poly-4,4'-azobenzene-1,3,4-oxadiazole (orange) according to Figure 7 having a UV-acrylate adhesive in the adhesive layer 5.
    EXAMPLE 2 Continuous Fiber Cloth Support 4 of a Poly-1,4-phenylene-1,3,4-oxadiazole Copolymer and Poly-4,4'-Azobenzene-1,3,4-Oxadiazole (Orange) according to Figure 7 having a UV-acrylate adhesive in the adhesive layer 5.
    Example 3: support 4 made of continuous fiber fabric of a copolymer of poly-1,4-phenylene-1,3,4-oxadiazole and of poly-4,4'-azobenzene-1,3,4-oxadiazole (orange) according to Figure 7 showing a silicone adhesive in the adhesive layer 5.
    The other two examples 4 and 5 of the table relate to adhesive strips 1 according to the invention having supports 4 in orange fabrics known characteristically Zylon® (Example 4) and Arselon® S (Example 5). These Examples 4 and 5 show the values that are achieved when using conventional PBO / POD fabrics with coarse weaving.
    Comparative Example 1: Support 4 made of continuous polyethylene terephthalate (PET) fabric with a UV-acrylate adhesive in the adhesive layer 5.
    Comparative Example 2: Support 4 made of fiberglass continuous fiber fabric with a silicone adhesive in the adhesive layer 5
    The adhesive strips 1 according to the invention therefore make it possible to advantageously bring together, with respect to the state of the art, the following properties: High temperature resistance:> 175 ° C. (class T5 or E according to the LV 312 standard),
    Better flame resistance: class A according to LV 312 / ISO 3795,
    Good resistance to abrasion, in particular Class C or D according to LV 312 / ISO 6722.
    With regard to a comparison with the temperature classes obtained according to the state of the art, it will be emphasized here in particular that advantageously - and avoiding the use of anthraquinone posing a risk to health - it has been possible to reach according to the invention, the temperature class T5, and not only the class T3 as in EP 2 546 317 B1. As a result, the limitation to the long-term use temperature of 175 ° C is due to the fact that The relevant standard LV 312 currently indicates this as the highest temperature class. In a similar test with high temperature resistant silicone wrapped conductors, Example 2 also demonstrated strengths at a long term use temperature of 225 ° C.
    A set of conductors consisting of several wires 2 is wound by the adhesive tape 1 according to the invention, the wires 2 possibly having a sheath made of PVC polyvinyl chloride which is designated by reference 2a in FIG. In particular, high compatibility with conductors exists not only with PVC and other sheath materials containing halogens, such as, for example, perfluoroethylenepropylene (FEP) or ethylene tetrafluoroethylene (ETFE), but also with uses in the set of cables son 2 whose sheath 2a is made of synthetic materials free of halogens, such as radiation cross-linked polyethylene (XPE), polypropylene (PP) or silicone (VMQ). The invention is not limited to the embodiments presented and described, but also includes all the embodiments having the same effect in the sense of the invention. This applies for example to the application weight of the adhesive layer 5, which can vary in wide ranges, but also to other parameters, which can be adapted in wide ranges - regardless of the color of the adhesive tape 1 according to the invention and the nature of the fabric of its support 4 - in each case of use.
    In addition to the parameter ranges already mentioned, in particular for the support 4, the following ranges appear particularly advantageous for the broadest areas of use of an adhesive tape 1 according to the invention: a thickness in the range of 0.15 mm to 1.50 mm, preferably from 0.20 mm to 0.60 mm, according to the EN 1942 standard, a tear elongation in the range from 20% to 50%, preferably from 25% to 35%, according to EN 14410, a breaking force in the range of 100 N / cm to 600 N / cm, preferably in the range of 250 N / cm to 500 N / cm, according to EN 14410, adhesiveness to in the range of 2.0 N / cm to 6.0 N / cm, preferably in the range of 2.5 N / cm to 3.5 N / cm, according to DIN EN 1939, adhesiveness to a web back in the range of 1.5 N / cm to 5.0 N / cm, preferably in the range of 2.0 N / cm to 3.0 N / cm, according to DIN EN 1939, a acoustic insulation of at least class B according to LV 312, a resistance to abrasion at least class B, preferably of class C or D, according to LV 312 standard.
    In the representation shown in FIG. 8 of another embodiment of an adhesive strip 1 according to the invention, it is provided that a second layer of strip 1b is laminated on the first layer of strip 1a, which presents in the case shown the same width B2 as the width B1 of the first layer of tape la. On both sides, there are provided adhesive portions which exceed λ 1, U 2, the portion which exceeds λ 1 on one longitudinal side of the adhesive strip 1 having exactly the same dimension as the part which exceeds Ü 2 on the other longitudinal side of the strip adhesive 2, but they however have the adhesive layers 5a, 5b in opposite directions (in Figure 8, once upwards and once downwards). The total width B of the adhesive tape 1 is obtained by the sum of the widths of the adhesive parts which exceed λ 1, λ 2 and the width of the overlap area. The different supports 4a, 4b of the tape layers 1a, 1b may consist of different materials, the support 4a of the first tape layer 1a being able to consist, for example, of a nonwoven and the support 4b of the other layer. band 1b may for example be constituted by a fabric. By the particular construction, a contact of the adhesive surfaces with the product to be wrapped is largely avoided. As a result, when the product to be wrapped is, for example, a set of cables consisting of several individual conductors or individual wires 2, these individual wires 2 can move relative to one another and a lower bending rigidity of the beam is obtained. of cables 3 provided with the sheath. At least one of the two support layers 4a, 4b must be colored in the context of the invention.
    For the other two embodiments shown in FIGS. 9 to 12 of the invention, it is each time a wrapping means 1 for an elongated product which is also included in the concept of "adhesive strip 1 "according to demand, even when they have a relatively small length L. The embodiments shown may for example be sections of a longer band. As an elongated product, there is shown in particular in FIGS. 10 and 12 each time a set of electric cables provided with wires 2. The adhesive strip 1 having the width B is formed by the fact that a second support layer 4b is laminated on a first support layer la which comprises a first support layer 4a having an adhesive layer 5a. The second support layer 4b forms, over a width Be, a non-adhesive central zone of the adhesive strip 1 which serves - in particular exclusively - to the placement of the product 2 to be wrapped and which is delimited on both sides each time by a zone RI, R2. When this is for example constituted by a nonwoven, one can in this way simultaneously obtain a high acoustic insulation and a high abrasion resistance of the adhesive tape 1 according to the invention. The two edge regions R1, R2 can form, in the state of the assembly as shown in Figure 10, each time together, a fixing heel F located laterally next to the second support layer 4b disposed in the center. In each edge region R1, R2 is at least one hole, in the case shown two holes L1, L2, L1 ', L2'. A hole L1, L2 in one edge region R1 is each time associated with a hole L1 ', L2' in the other edge zone R2 symmetrically with respect to the axis such that the holes L1 , L2, L1 ', L2' can be placed on each other by folding the adhesive strip 1 along a main axis XX (Figure 9) extending through the central zone 4b or by a curvature around an axis YY (FIG. 10) extending parallel to this main axis XX, remote from the adhesive strip 1, as shown in FIG. 10. The axis YY remote from the adhesive strip 1 is identical to the longitudinal axis of the elongated product 2. For holes L1, L2, L1 ', L2' it may be, in a simpler manner from a technical point of view of manufacture and thus preferred, punched holes. On the basis of holes L1, L2, L1 ', L2' made beforehand, through which, as shown in FIG. 10 and in FIG. 12, fastening means 8 may be passed, such as fixing clips, the adhesive strip 1 according to the invention makes it possible to produce as longitudinal sheath a sleeve M also called sheath (sleeve) for the elongate product, which already comprises, thanks to a particular arrangement, the possibility of a simple fixing with the fixing means 8 to another room, for example a vehicle body. The need for a subsequent attachment of fastening means 8 to the longitudinal sheath M by additional adhesive strips or the like is thus eliminated. The size and shape of the holes L1, L2, L1 ', L2' may preferably be adapted to the size and shape of the fastening means 8 in such a way that the fastening means 8 is held by shape complementarity or by force in the holes L1, L2, L1 ', L2'. Here again, the different supports 4a, 4b of the belt layers 1a, 1b may be constituted by different materials, the support 4b being able for example to be constituted by a nonwoven and the support 4a of the first layer of the belt (unique ) may for example be constituted by a fabric to combine a high acoustic insulation and a high abrasion resistance with each other. In this embodiment, at least the first support layer 4a located outside in the mounting state must be colored within the scope of the invention.
    In the embodiment shown in FIGS. 11 and 12 - unlike the embodiment in FIGS. 9 and 10 - a length L of the enveloping means extending in the direction of the main axis XX is not greater at a width B of the wrapping means extending transversely to the direction of the main axis XX, whereupon the wrapping means 1 can form a fastening collar S for the elongate product. This is shown in the drawing in FIG. 12, which shows by way of example a mounting state of the corresponding embodiment, by a reference S placed in parentheses behind reference numeral 1. Moreover, it is characteristic for this mode of realization that only a hole Ll, Ll 'is located in each edge zone RI, R2. The embodiment is adhesively primed over the entire surface by the adhesive layer 5. However, it could also give up the adhesive layer 5 and use only the support 4. A particularity of this embodiment also lies in the that one of the holes L1 'is in the form of a longitudinal hole. Through this longitudinal hole, it is advantageously possible to achieve the field of use of the wrapping means according to the invention more universally, in that it can be used for different diameters of the product to be wrapped.
    It is explicitly emphasized that the exemplary embodiments are not limited to all the features in combination, but that each partial feature may also have an inventive significance per se, independently of all the other partial features.
    An analogous representation of an adhesive tape 1, as in FIG. 8, is also found in the description of EP 1 315 781 B1, where it is mentioned in this context that the various other adhesive tape embodiments described therein may also be realized according to the invention.
    In the embodiment according to FIG. 9 it is possible for example - in particular when the second support layer 4b consists of a nonwoven - to apply another adhesive layer on the second support layer 4b.
    Furthermore, the invention so far is not limited either to the combinations of features defined in claim 1 and the other independent claims, but can also be defined by any other combination of specific characteristics of all the individual characteristics disclosed in total. This means that basically every single feature of claim 1 and the other independent claims may be omitted or replaced by at least one individual feature disclosed elsewhere at the request.
