    TIRE WITH AN ORGAN FIXED TO ITS SURFACE AND METHOD OF FASTENING AN ORGAN TO THE SURFACE OF A TIRE
    Field of the Invention [0001] The present invention relates to tires, and more particularly to tires having a member attached to their surface. State of the art [0002] More specifically, the invention relates to the attachment of a particular electronic member, such as a pressure sensor, on a tire. The recent development of these bodies is limited by the difficulty of fixing a fast and durable object on the surface of a tire.
    [0003] EP 906 839 A2 discloses a tire comprising an inner surface and an outer surface, a reception zone disposed on one of these inner and outer surfaces, an adhesive layer disposed on this reception zone and a member with a rubber fixing layer attached to the receiving area by the adhesive layer, wherein the adhesive layer is a rubber gum rubber vulcanizable at room temperature for a period of about 48 to 72 hours.
    But this fixing operation is long and expensive.
    Brief description of the invention [0005] The subject of the invention is a similar tire, characterized in that the adhesive layer is based on a silanized polyether.
    The use of such an adhesive layer has the advantage of allowing a faster implementation of the organ and to have no solvent or dissolution while maintaining excellent mechanical strength of the binding.
    [0007] Preferably, the silanized polyether is an alkoxy silane functional telechelic polyether.
    By way of example, the alkoxysilane may be methyldimethoxysilane.
    The polyether may advantageously be a polyoxypropylene.
    2015PAT00286 EN
    The member may be an electronic device. It can also be a housing adapted to receive an electronic device. The organ can also be a rubbery patch.
    The thickness of the adhesive layer is preferably between 1 and 1.5 mm.
    The invention also relates to a tire comprising two beads, two flanks connected to the beads, a vertex connected to the ends of the two sides with a crown reinforcement and a radially outer tread, wherein, the tire having a outer side and an inner side, the member is fixed to the radially inner surface of the apex, axially on the outside of the tire.
    By outer side of the tire means the side of the tire to be disposed on the outside of the vehicle relative to the median plane of the tire.
    Advantageously, the tire having a maximum axial width LT, the axial distance between the center of gravity of the member and the median plane EP of the tire is at least equal to 5% of the maximum axial width LT of the tire.
    This position reduces the consequences of the presence of a member on the inner surface of the tire under conditions of very high speed of rolling and with a camber imposed.
    Preferably, the axial distance between the center of gravity of the member and the median plane EP of the tire is at most equal to 25% of the maximum axial width LT of the tire.
    This avoids the shoulder area of the tire, area always very stressed.
    Very advantageously, the tread comprising a set of circumferential grooves, the center of gravity of the member is located in line with a circumferential groove of the tread of the tire.
    This position facilitates the evacuation of calories related to the presence of the body in rolling.
    By groove is meant any recessed area of the tread generally p.irp.rmfprpntipllp Pt lnnlpmpnt 1p tnnr nnsnmatiniif dplimitpp nar dps narnis dp material facing each other and distant from each other. a non-zero distance, of a depth at least equal to 2 mm when the tire is new These walls can not come into contact with each other under the usual conditions of rolling. A circumferential groove has two generally circumferential direction walls, one axially inner and the other axially outer.
    By positioning perpendicular to the circumferential groove, it is meant that the center of gravity of the member is axially external to the axially inner wall of the groove and axially inner to the axially outer wall of the groove with a groove. axial positioning tolerance of 5 mm.
    According to another advantageous embodiment, the center of gravity of the member is located radially in line with a rib of the tread. Indeed, under heavy loads, the first buckling of the top are not located under the ribs, but under the grooves. These buckles generate significant deformations that can deteriorate the adhesive layer between the inner liner and the body. In this case, positioning the member vertically above a rib improves the endurance of the adhesive layer and therefore of the tire.
    By ribs is meant a raised element formed on a tread, this element extending in the circumferential direction and generally around the tire, a height of at least 2 mm when the tire is new. A rib comprises two axial walls and a contact face, the latter being intended to come into contact with the ground while driving. A circumferential rib has two generally circumferential direction walls, one axially inner and the other axially outer. A rib may not be circumferentially continuous but be notched in particular in the case of a tire dedicated to winter use.
    By positioning vertically above the rib, it is meant that the center of gravity of the member is axially external to the axially inner wall of the rib and axially inner to the axially outer wall of the rib with a tolerance. axial positioning of 5 mm.
    According to another object, the invention relates to a method of fixing a member with a rubber fixing layer on a reception area of one of the inner and outer surfaces of a tire, wherein: - an adhesive layer based on silanized polyether is applied to the reception area and / or to the outer surface of the rubber-fixing layer of the member; the organ is placed against the reception area; and - the adhesive layer is allowed to crosslink.
    Advantageously, before setting up the body on the reception area of the surface of a vulcanized tire, it cleans the reception area.
    This cleaning can be achieved by brushing or by a high pressure water jet or a laser beam.
    This treatment makes it possible to remove most of the release agents used and thus allows a durable bonding of the member to the surface of the tire.
    According to another embodiment, it is set up on the reception area of the tire before vulcanization of the tire a protective film of the reception area and this protective film is removed from the reception area. prior to applying to the receiving area and / or the radially outer surface of the member an adhesive layer based on silanized polyether.
    Preferably, the protective film is a thermoplastic film selected such that the peel force of said film of the reception zone is less than 1 N / mm at 20 ° C and preferably less than 0.5 N / mm.
    Preferably, the protective film is chosen from the group of polyesters and films comprising at least one fluorinated polymer.
    By way of example, the fluorinated polymer may comprise a fluorinated ethylene-propylene copolymer (FEP).
    Advantageously, the Tg (or Tf, where appropriate) of the protective film is greater than the maximum temperature of cooking rubber mixture of the reception area.
    According to a preferred embodiment, the adhesive layer is applied by spraying.
    DETAILED DESCRIPTION OF THE INVENTION In the present description, unless expressly indicated otherwise, all the percentages (%) indicated are% by weight.
    On the other hand, any range of values designated by the expression "between a and b" represents the range of values from more than a to less than b (that is to say terminals a and b excluded). ) while any range of values designated by the expression "from a to b" signifies the range of values from a to b (that is to say, including the strict limits a and b).
    Silicone Polyether Based Adhesive The Applicants have discovered that the use of a new family of silanized polyether-based adhesives improves the bonding of a member to an inner or outer surface of a tire. .
    The adhesives used are based on functionalized polyoxypropylenes methoxysilane at the end of the chain:
    A high-weight polyoxypropylene is first functionalized with an allyl group at each of the two ends of the chain and is then hydrosilylated to finally obtain a telechelic functional polyether methyldimethoxysilane.
    These polymers combine quite well the advantages of silicones (aging resistance) and polyurethanes (cohesion of the material). They are free of isocyanate and solvent.
    A typical formulation of adhesive or putty based on silanized polyether may contain in addition to the functional polyether: filler (s), plasticizer, pigment, adhesion promoter, dehydrating agent, catalyst, thixotropic agent and optionally antioxidant and UV stabilizer or according to use.
    An example of a formulation (Kaneka DKB-5 sealant) (1) is presented in the following table:
    (l) CABOT-CAB-O-SIL TS-720 in MS-Polymer Sealants (2010) p: part by weight per 100 parts of elastomer, here the silanized polyether; pcm: percentage by weight relative to 100 g of adhesive.
    After application of the silanized polyether-based adhesive (Silyl-Terminated PolyEther or STPE), it polymerizes with the moisture of the air (2).
    This polymerization is carried out in two stages:
    Step 1: Conversion by hydrolysis of methoxysilane to silanol:
    Step 2: Condensation of the silanol with a methoxysilane to form a siloxane bridge:
    (2) CRAY VALLEY - One-component Moisture Curing Methoxysilane Sealants (2001) Silanized polyether adhesives are commercially available in particular from Bostik: BOSTIK-Simson-ISR-7003, it is a mono adhesive -component.
    The use of such an adhesive has the advantages of using no solvent or no dissolution and having a kinetics of crosslinking much faster than a conventional cold vulcanizing bonding gum layer, such as Gray gum supplied by Tech International, while having excellent mechanical strength. This gum binding requires the use of a dissolution ("vulcanization Chemical fluid") which comprises an ultra vulcanization accelerator and which is to be applied after the preparation of the surfaces to be bonded.
    Three main parameters involved in the kinetics of crosslinking of the cited adhesive of Bostik: temperature, hygrometry and thickness.
    Considering normal conditions of hygrometry (50% relative humidity) and a temperature of 23 degrees Celsius, a layer of bonding gum thickness of 0.3 mm will crosslink in about forty hours then that an adhesive layer 1 mm thick of the cited Bostik adhesive will crosslink in less than six hours. At a temperature of 35 degrees Celsius and 80% relative humidity, the crosslinking time is reduced by a factor of two.
    This is a very important decrease for the ease of use of the adhesive layer for fixing a member after vulcanization of a tire.
    The part of the tire on which is fixed the organ according to the invention as well as the rubbery attachment layer of the organ are rubber compositions based on at least one essentially unsaturated diene elastomer, at least one essentially saturated diene elastomer or a mixture of these two types of elastomers. The rubber composition also usually contains such fillers as carbon black or silica as well as conventional additives and in particular the agents for protection against ozone, oxidation, etc.
    By "diene" elastomer is meant in known manner an elastomer derived at least in part (i.e. a homopolymer or a copolymer) of monomers dienes (monomers bearing two carbon-carbon double bonds, conjugated or not). These diene elastomers can be classified into two categories: "essentially unsaturated" or "essentially saturated".
    In general terms, the term "essentially unsaturated" diene elastomer is used herein to mean a diene elastomer derived at least in part from conjugated diene monomers having a level of units or units of diene origin (conjugated dienes) which is greater than 15 % (mole%).
    It is thus, for example, that diene elastomers such as butyl rubbers or copolymers of dienes and alpha-olefins EPDM type (ethylene-propylene-diene terpolymer) do not fall within the previous definition and may be especially described as "essentially saturated" diene elastomers (low or very low diene origin, always less than 15%).
    According to one embodiment of the invention, the part of the tire on which is fixed the body according to the invention is the sidewall of the tire. The composition of this part of the tire may then contain at least one essentially saturated diene elastomer, in particular at least one EPDM copolymer, whether this copolymer is for example used or not in admixture with one or more of the essentially unsaturated diene elastomers.
    According to another embodiment of the invention, the part of the tire on which is fixed the applique according to the invention is an inner rubber tire or any other layer or object of the inner portion of the tire. The figures in the appendix illustrate this embodiment and more particularly an attachment of the member under the tread of the tire. The composition of this portion of the tire may then contain at least one substantially saturated diene elastomer copolymer type of isobutene and isoprene (butyl rubber), as well as halogenated versions of these copolymers.
    DESCRIPTION OF THE FIGURES [0056] Complementary elements of the invention are now described with the aid of the accompanying drawing, presented in a non-limiting manner, in which: FIG. 1 very schematically represents a radial section of a tire; according to one embodiment of the invention; - Figure 2 shows a partial radial section of a tire blank according to one embodiment of the invention; FIG. 3 illustrates a member with a fixing layer; - Figure 4 shows the body attached to the surface of the tire; and - Figure 5 shows the member fixed to the tire surface at another preferred position.
    FIG. 1 schematically represents a radial section of a pneumatic or pneumatic tire incorporating in a reception area 13 a protective film 12 according to one embodiment of the invention.
    This tire 1 comprises a vertex 2 reinforced by a crown reinforcement or belt 6, two sidewalls 3 and two beads 4, each of these beads 4 being reinforced with a rod 5. The crown reinforcement 6 is surmounted radially outwardly. of a rubbery tread 9. A carcass reinforcement 7 is wound around the two rods 5 in each bead 4, the upturn 8 of this armature 7 being for example disposed towards the outside of the tire 1. The carcass reinforcement 7 is in known manner constituted of at least one sheet reinforced by so-called "radial" cables, for example textile or metal, that is to say that these cables are arranged substantially parallel to each other and s' extend from one bead to the other so as to form an angle of between 80 ° and 90 ° to the median circumferential plane (plane perpendicular to the axis of rotation of the tire which is situated halfway between the two b 4 and passes through the middle of the crown reinforcement 6). A waterproof layer (or "inner liner" or "inner liner") 10 extends from one bead to the other radially inwardly relative to the carcass reinforcement 7. Figure 1 also indicates the median plane EP of the tire. The median plane is a plane perpendicular to the axis of rotation of the tire, located midway between the two beads and passing through the middle of the crown reinforcement. This figure also indicates the maximum axial width of the tire LT. This is measured at the flanks, the tire being mounted on its rim and slightly inflated, that is to say inflated to a pressure equal to 10% of the nominal pressure as recommended, for example by the tire. Rim Association or TRA.
    The tire 1 is such that its inner wall comprises a given reception area 13 covered radially internally by a protective film 12.
    The surface of the reception area 13 must be sufficient to obtain a robust attachment of the body, the skilled person will adjust the size of the protective layer 12 depending on the size and mass of the organ to fix.
    The separable protective film 12 is a thermoplastic film comprising, by way of example, a fluorinated polymer. The thermoplastic film is extensible with low rigidity and has a plastic behavior. This film must have a Tg (or Tf, if applicable) greater than the vulcanization temperature of the tire. An example of a suitable film is Aerovac Systèmes France film A5000. This film comprises a fluorinated ethylene-propylene copolymer or FEP. This film has a maximum operating temperature of the order of 204 ° C. and has a breaking elongation greater than 300%. Its thickness is 25 pm. These characteristics allow it, in an exemplary embodiment of the invention, to be put in place directly on the drum or making the tire.
    As indicated in Figure 2, the separable protective film 12 preserves the reception area 13 of any contact with the tire manufacturing drum and with the baking membrane of the vulcanization mold. The particular nature of this protective film allows it to be removed from the inner surface of the tire after vulcanization. The removal of this protective film returns to the surface of the reception area of the tire all its properties. The protective film 12 can be removed without tearing.
    The pneumatic or pneumatic tire of FIG. 1 can be manufactured, as indicated in FIG. 2, by integrating the protective film into a non-vulcanized blank of the tire 1 by using a manufacturing drum and the other techniques customary in the invention. the manufacture of pneumatic tires. More specifically, the radially innermost separable protective film 12 is applied first to the manufacturing drum 15. Then, all the other usual components of the tire are applied successively.
    After shaping, the crown plies and the tread are placed on the blank of the tire. The thus completed blank is placed in a baking mold and is vulcanized. During vulcanization, the protective film protects the mold's cooking membrane from contact with the reception zone 13.
    At the outlet of the baking mold, the protective film 12 is always attached to the reception area 13.
    The protective film 12 can be easily removed at the outlet of the tire vulcanization mold. It is also possible, and preferable, to leave in place this protective film until the time of fixation of the organ.
    The protective film may also be applied to the reception area 13 chosen on the surface of the tire after the conformation of the tire blank and before introducing it into the vulcanization mold.
    Figure 3 schematically shows a member 20 having a housing 22 and a fastening layer 24. The material of the fastening layer 24 is a rubbery mixture. Those skilled in the art will be able to adapt the thickness of the fixing layer according to that of the adhesive layer and the size and mass of the organ.
    Figure 1 thus shows a tire 1 ready to receive an organ.
    It is also possible to fix a member on a reception area 13 of a vulcanized tire customary, that is to say without it comprises a protective film protecting the reception area.
    In this case, it is preferable to clean this reception area before fixing the body.
    This cleaning can be achieved, for example, by means of a high pressure water jet. This cleaning makes it possible to remove most of the mold release agents that have been placed on this surface before vulcanization of the tire to facilitate the take-off of the baking membrane of the tire vulcanization mold.
    After cleaning, the surface of the reception area of the inner liner is dried.
    It is also possible to perform this cleaning by brushing or with a laser beam.
    Figure 4 shows the entire tire of Figure 1 and the member 20 fixed on its inner surface on the inner liner. This tire is characterized in that the adhesive layer 11 is based on a silanized polyether. The adhesive layer ensures that the member 20 is held in place.
    The attachment of the member 20 to the tire surface is performed easily and quickly. After removing the protective film 12 from the reception area 13 of the tire 1 if necessary: - a layer of adhesive based on silanized polyether is applied to the surface of the reception zone; an application of the adhesive by spraying is also possible: in this case it can be done at a higher temperature to promote the spraying technique (lowering the viscosity of the adhesive); the attachment layer of the member is placed against the surface of the adhesive layer 11, preferably with a suitable contact pressure; then, the adhesive layer is allowed to crosslink at room temperature as previously described.
    The crosslinking of the adhesive layer creates two high-quality bonds: between the adhesive and the inner liner on the one hand, and between the adhesive and the rubber-like attachment layer on the other hand . The quality of these bonds is linked to an interpenetrating network originating from the polycondensation of the functional alkoxysilane oligomers.
    Indeed, the macromolecular chains of the rubber mixes and the silanized polyether adhesive are partially compatible, which allows an intermolecular diffusion between the macromolecular chains to intervene when the adhesive layer is brought into contact with the inner liner. and the attachment layer of the organ.
    In addition, this diffusion is favored on the one hand by the good mobility of the silanized polyether (not yet crosslinked) and on the other hand by the presence of small molecules such as the adhesion promoter, the dehydrating agent and even the plasticizer (the three acting as a pseudo-solvent). Although it is only very superficial, this intermolecular diffusion is capable of generating finally an interpenetrating network after crosslinking the silanized polyether. This entanglement of the molecules of each of the materials, with disappearance of the interface and creation of an interphase on a small thickness, must be responsible for the good adhesion observed and measured.
    In the example shown, the member is attached to the inner surface of the tire, it is also possible to place it on an outer surface of the tire, for example on the sidewall of the tire.
    The surfaces of the reception area 13 and therefore the adhesive layer 11 must be sufficient to obtain a robust attachment of the body, the skilled person will adjust the size of the adhesive layer 11 according to the size and mass of the organ to fix.
    Tests The interest of the adhesive according to one of the subjects of the invention is shown by the results of a very high speed resistance test.
    The tires concerned are of dimension 305 / 30ZR20 103Y, with an inner side I and an outer side E, of maximum axial width 313 mm and are tested with a camber angle of 2.5 ° in order to take into account the technical requirements of a vehicle to which they are specifically dedicated. The test consists of rolling on a metal wheel of 8.5 m circumference at a pressure of 3.2 bar and a load of 587 daN regulated. The tire rolls in increasing speed increments, lasting 20 minutes each, the increment in speed is 10 km / h. The tires are classified according to the maximum speed reached and the driving time during the last speed step reached.
    The organ is in this test a pressure and temperature sensor placed in a rubber mix housing based on polybutadiene 1-4 cis and halogenated butyl, as described in US 8,763,658 B2.
    A comparison is made between a non-equipped tire of a member, a tire with a fixed member with an adhesive layer of 0.3 mm thick Gray gum supplied by Tech International and a tire with a member fixed with a layer adhesive, about 1 mm thick, from Bostik-Simson-ISR-7003.
    The tire without the body reaches the plateau 370 km / h and rolls at this speed for 11 minutes. The tire according to the state of the art, namely equipped with the electronic element, a pressure sensor with a mass of 7 g, positioned according to the state of the art, and therefore installed in the tire of such so that its center of gravity is in the equatorial plane at the positioning tolerance close to 1% of the maximum axial width, this tire reaches the speed step 340 km / h and has a failure after one minute of driving at this condition. This result compared to that of the tire not equipped with the electronic organ, demonstrates the decline in endurance performance at very high speed induced by the presence of the electronic member. This failure is related to the increase of the temperature in the top of 15 ° C seen by digital simulation directly above the sensor, this at the same speed between the tire without an electronic component and the pneumatic tire due to the electronic organ according to the state of the art.
    The inventors have tested two embodiments of the invention. The first embodiment illustrated in FIG. 5 consists in installing the electronic member 20 at a distance from the equatorial plane of 16% of the maximum axial width LT, in line with a rib 30 of the tread 9. In this case, the tire according to the invention reaches the speed step of 360 km / h and rolls for 15 minutes on this landing. This compared to the result of the tire equipped with the electronic member positioned in the equatorial plane, namely maximum plateau reaches 340 km / h, demonstrates the improvement of the high-speed endurance of the tire provided with the electronic member as described by FIG. 'invention.
    The second embodiment illustrated in FIG. 4 consists in installing the electronic member 20 at a distance from the equatorial plane of 7% of the maximum axial width, in line with a groove 40 of the tread 9. In this case, the tire according to the invention reaches the speed threshold of 370 km / h and rolls for 15 minutes on this bearing. The maximum peak temperature drops by almost 15 ° C. This result compared to the result of the tire equipped with the electronic element positioned in the equatorial plane, ie maximum plateau reaches 340 Km / h, shows the improvement of the high speed endurance of the tire provided with the electronic member such that described by the invention according to this second embodiment.
    No difference in performance was observed between the two adhesive layers tested. On the other hand, a complementary test using a glue based on cyanoacrylate showed that it is unsatisfactory.
    These results show that the use of an adhesive layer based on silanized polyether is an interesting alternative to the use of a conventional bonding gum such as Gray gum Tech International.
