专利说明:

[1] The present invention relates to a process for the production of composite materials based on gel, the materials obtained by this process as well as the use of them in various applications.
[2] A composite material is basically a combination of two or more materials, each of which retains its own distinctive properties. The resulting material has characteristics that are not characteristic of the components in isolation. Most commonly, composite materials have a volume phase, which is continuous, called the matrix; and a dispersed, non-continuous phase called reinforcement. Some other examples of basic composites include concrete (cement mixed with sand and aggregate), reinforced concrete (concrete steel rebar) and fiberglass (glass fibers in a resin matrix).
[3] The following are some of the reasons why composites are selected for certain applications: - High strength to weight ratio (high tensile strength of low density) - High resistance to creep - High tensile strength at high temperatures - High stiffness
[4] Typically, reinforced materials are strong, while the matrix is usually a flexible or resistant material. If the composite is designed and manufactured correctly, it combines with the strength of the reinforcement with the stiffness of the matrix to achieve a combination of desirable properties not available in any conventional simple material. For example: polymer / ceramic composites have a larger modulus than the polymer component, but are not as fragile as ceramics.
[5] Since the reinforcement material is of primary importance in the strengthening mechanism of a composite, it is convenient to classify the composites according to the characteristics of the reinforcement. The following three categories are commonly used: a) “fiber reinforced”, where the fiber is the component that carries the primary load. b) “reinforced particle”, in which the charge is formed by the matrix and the particles. c) “strengthened dispersion”, in which the matrix is the largest component that carries the load. d) “structural composites”, in which the properties depend on the constituents and the geometric design.
[6] Generally, the strength of the composite depends mainly on the amount, combination and type of fiber (or particle) reinforcement in the resin. In addition, the composite is often formulated with fillers and additives that change processing and performance parameters.
[7] Advanced composites use a combination of resins and fibers, usually carbon / graphite, kevlar or fiberglass with an epoxy resin. The fibers provide high rigidity, while the surrounding polymer resin matrix holds the structure together. The fundamental design concept of composites is that the volume phase accepts the load over a wide surface area and transfers this to the reinforcement material, which can carry out a larger load. These materials were first developed for use in the aerospace industry because of a certain application they have greater rigidity by weight for resistance in weight than metals. This means parts can be replaced with lighter weight parts made from advanced composites.
[8] Thus, in the prior art it is well known to implement polymers and the others in composites, which, however, are relatively expensive and environmentally hostile. In addition, the addition of fillers as mentioned generally requires surface treatment, containing high processing costs.
[9] Thus, there is still a need for the provision of cost-efficient and environmentally favorable composite materials.
[10] Observing for the solution of this objective, several materials were investigated, inter alia, cellulose and calcium carbonate.
[11] Cellulose is the structural component of the primary cell wall of green plants and is the most common organic compound on earth. It is of greatest interest in many Orders and industries.
[12] Cellulose pulp as a raw material is processed out of wood or plant stems such as hemp, flax and manila. Pulp fibers are built mainly from cellulose and other organic components (hemicellulose and lignin). The cellulose macromolecules (1-4 glycosidic compounds linked by the P-D-Glucose molecules) are linked together by hydrogen bonding to form a so-called primary fibril (micelle) that has crystalline and amorphous domains. Several primary fibrils (around 55) form a so-called microfibril. Around 250 of these microfibrils form a fibril.
[13] The fibrils are arranged in different layers (which may contain lignin and / or hemicellulose) to form a fiber. The individual fibers are linked together by lignin as well.
[14] When the fibers become refined under applied energy they become fibrillated as the cell walls are broken and removed in the linked bands, that is, in the fibrils. If this break is continued, separating the fibrils from the fiber body, it releases the fibrils. The breakdown of fibers in microfibrils is referred to as "microfibrillation". This process can be continued until there are no left fibers and only nanosize (thickness) fibrils remain.
[15] If the process still continues and breaks these fibrils into smaller fibrils, they eventually become fragments of cellulose or nanofibrillar gels. Depending on how far this last step is taken some nanofibrils may remain between the nanofibrillar gel. The breakdown of primary fibrils can be referred to as “nanofibrillation”, where they can be the smooth transition between the two regimes. The primary fibrils form a gel in a watery environment (stable target network of primary fibrils) that can be referred to as a “nanofibrillar gel”. The gel formed from nanofibrils can be considered to contain nanocellulose.
[16] Nanofibrillary gels are desirable as they usually contain many thin fibrils, considered to be made up partly of nanocellulose, showing a stronger bonding potential alone, or in any other material present, than from fibrils that are not from this one. thin or do not exhibit the nanocellulosic structure.
[17] From unpublished European Patent Application No. 09 156 703.2, nanofibrillar cellulose gels are known. However, there is no knowledge regarding the formation of composite materials.
[18] It has been observed that such cellulose gels can be formed in composite materials, which can be produced easier / faster by adding fillers and / or pigments in such gels and result in improved functionality and are environmentally friendly compared to other composite materials.
[19] Thus, the above problem is solved by a process for the production of composite materials that comprises nanofibrillar cellulose gels, which is characterized by the following steps: a) supplying cellulose fibers; b) supply at least one filler and / or pigment; c) combining the cellulose fibers from step a) and the at least one filler and / or pigment from step b); d) fibrillar the cellulose fibers in the presence of at least one filler and / or a pigment until a gel is formed; e) supply at least one charge and / or an additional pigment; f) combining the gel from step d) with at least one filler and / or an additional pigment from step e).
[20] Nanofibrillary cellulose in the context of the present invention means fibers, which are at least partially breaking primary fibrils. If these primary fibrils are in an aqueous environment, a gel (target stable network of primary fibrils considered at the limit of clarity to be essentially nanocellulose) is formed, which is indicated as a “nanofibrillar gel”, in which it is a smooth transition between nano fibers and nanofibrillary gel, comprising nanofibrillary gels containing a variation in the length of nanofibrils, all of which are comprised by the term nanofibrillary cellulose gels according to the present invention.
[21] In this regard, fibrillar in the context of the present invention means any process that predominantly breaks the fibers and fibrils along its long axis resulting in a decrease in the diameter of the fibers and fibrils, respectively.
[22] According to the process of the present invention, fibrillation of cellulose fibers in the presence of at least one filler and / or a pigment provides a nanofibrillar cellulose gel. Fibrillation is performed until the gel is formed, in which the formation of the gel is verified by monitoring the viscosity depending on the cut rate. In the step-by-step increase in the cut rate a certain curve reflects a decrease in viscosity is obtained. If, subsequently, the cut rate is reduced step by step, the viscosity increases again, but the corresponding values in at least part of the cut rate range as zero cut methods are lower than when the cut rate increases, graphically expressed by hysteresis manifests when viscosity is plotted against a cut-off rate. As soon as this behavior is observed, the nanofibrillary cellulose gel according to the present invention is formed. Further details regarding the production of the nanofibrillar cellulose gel can be taken from unpublished European Patent Application No. 09 156 703.
[23] The cellulose fibers, which can be used in the process of the present invention can be such contained in the thermomechanical, chemiomechanical, mechanical, chemical and natural pulps. Especially useful are the pulps selected from the group comprising eucalyptus pulp, spruce pulp, pine pulp, strip pulp, hemp pulp, cotton pulp, bamboo pulp, bagasse and mixtures thereof. In one embodiment, all or part of this cellulose fiber can be emitted from the step of recycling the material comprising cellulose fibers. In this way, the pulp can also be recycled and / or depigmented pulp.
[24] The size of the cellulose fibers is not critical at first. In general, any fibers commercially available and processed in the device used for their fibrillation are useful in the present invention. Depending on its origin, cellulose fibers can have a length of 50 mm to 0.1 gm. Such fibers, as well as having a length of preferably 20 mm to 0.5 µm, more preferably 10 mm to 1 mm and typically 2 to 5 mm, can be advantageously used in the present invention, where also shorter and longer fibers long ones can be useful.
[25] It is advantageous for use in the present invention that cellulose fibers are supplied in the form of a suspension, especially an aqueous suspension. Preferably, such suspensions have a solids content of 0.2 to 35% by weight, more preferably from 0.25 to 10% by weight, even more preferably from 0.5 to 5% by weight, especially from 1 to 4% by weight, more preferably 1.3 to 3% by weight, for example, 1.5% by weight.
[26] At least one charge and / or pigment from steps b) and e) are independently selected from the group comprising precipitated calcium carbonate (PCC); natural ground calcium carbonate (GCC); surface modified calcium carbonate; dolomite; baby powder; bentonite; clay; magnesite; SATIN WHITE; sepiolite, huntite, diatomite; silicates and mixtures thereof.
[27] Precipitated calcium carbonate, which may have a valeritic, calcitic or aragonitic crystal structure and / or natural crushed calcium carbonate, which may be selected from marble, limestone and / or chalk, are especially preferred.
[28] In a special embodiment, the use of distinct ultra-thin precipitated prismatic, scalenoid or rhombohedral calcium carbonate may be advantageous.
[29] The fillers and / or pigments can be supplied in the form of a powder, although these are preferably added in the form of a suspension, such as an aqueous suspension. In this case, the solids content of the suspension is not critical as long as they are a pumpable liquid.
[30] In a preferred embodiment, the filler and / or pigment particles from step b) have an average particle size of 0.01 to 15 gm, preferably 0.1 to 10 gm, more preferably 0, 3 to 5 gm, especially from 0.5 to 4 gm and more preferably from 0.7 to 3.2 gm, for example, 2 gm.
[31] For determining the weight of the average particle size d50, for particles having a d50 greater than 0.5 gm, a Sedigraph 5100 device from Micromeritics, USA was used. The measurement was performed in an aqueous solution of 0.1% by weight of Na4P2O7. The samples were dispersed using a high speed shaker and ultrasound. For the determination of the average particle size volume for particles having a d50 500 nm, a Malvern Zetasizer Nano ZS from Malvern, UK was used. The measurement was performed in an aqueous solution of 0.1% by weight of Na4PZO7. The samples were dispersed using a high speed shaker and ultrasound.
[32] It has been particularly advantageous, if the fillers and / or pigments added in step e) are preferably a fine product in terms of particle size and especially preferably comprise at least a fraction of particles having an average diameter d50 in the nanometer range, contrary to the pigments and / or fillers used in gel formation, which are otherwise thick.
[33] Thus, it is still preferred that the charge particles and / or pigment from step e) have an average particle size of 0.01 to 5 µm, preferably from 0.05 to 1.5 µm, more preferably from 0.1 to 0.8 µm and more preferably from 0.2 to 0.5 gm, for example, 0.3 gm, where a particle size is determined as mentioned above.
[34] The filler (s) and / or pigment (s) may be associated with dispersing agents such as those selected from the group comprising homopolymers or copolymers of polycarboxylic acids and / or their salts or derivatives such as ethers based on, for example, acrylic acid, methacrylic acid, maleic acid, fumaric acid, itaconic acid; for example, acrylamide or acrylic esters such as methyl methacrylate or mixtures thereof; alkyl polyphosphates, phosphonic, citric and tartaric acids or their salts or esters; or mixtures thereof.
[35] The combination of fibers and at least one filler and / or pigment from steps b) and / or e) can be accomplished by adding the filler and / or pigment to the fibers in one or several steps. Also, the fibers can be added to the filler and / or the pigment in one or several steps. The filler and / or pigment from step b) as well as the fibers can be added completely or in portions before or during the fibrillar step. However, addition before fibrillar is preferred. During the fibrillation process, the size of the fillers and / or pigments as well as the size of the fibers can change.
[36] Preferably, the weight to fiber ratio for fillers and / or pigments from step b) on a dry weight basis is 1:33 to 10: 1, more preferably 1:10 to 7: 1, even more preferably from 1: 5 to 5: 1, typically from 1: 3 to 3: 1, especially from 1: 2 to 2: 1 and more preferably from 1: 1.5 to 1.5: 1, for example, 1: 1.
[37] The dosage of the filler and / or pigment in step b) can be critical. If there is not much of the filler and / or pigment, it can influence the formation of the gel. Thus, if no gel formation is observed in the specific combination, it must be necessary to reduce the amount of the filler and / or the pigment.
[38] Furthermore, in one embodiment, the combination is stored for 2 to 12 hours, preferably 3 to 10 hours, more preferably 4 to 8 hours, for example, 6 hours, before fibrillar, as this ideally results in swelling of the fibers facilitating fibrillation.
[39] Fiber swelling can be facilitated by storage at increased pH, as well as the addition of similar cellulose solvents eg copper (II) ethylenediamine, sodium-iron tartrate or lithium-chlorine / dimethylacetamine, or any another method known in the art.
[40] Fibrillation is performed using any useful device, therefore. Preferably the device is a homogenizer. This can also be an ultrathin friction crusher such as the Supermasscolloider of Masuko Sangyo Co. Ltd, Japan or one as described in US 6,214,163 or US 6,183,596.
[41] Suitable for use in the present invention are any commercially available homogenizers, especially high pressure homogenizers, in which suspensions are compressed under high pressure through a restricted opening, which may comprise a valve and are discharged from the opening restricted at high pressure against a hard impact surface directly in front of the restricted opening. Pressure can be generated by a pump such as a piston pump and the impact surface can comprise an impact ring extending around the annular valve opening. An example for a homogenizer that can be used in the present invention is Ariete NS2006L by GEA Niro Soavi. However, inter alia, such homogenizers such as APV Gaulin series, FIST HL series or Alfa Laval SHL series can be used.
[42] In addition, devices, such as ultrathin friction crushers, for example, a Supermasscolloider, can be advantageously used in the present invention.
[43] It is still preferred that the weight ratio of fibers for loading and / or pigment from step e) on a dry weight basis is 1: 9 to 99: 1, preferably 1: 3 to 9: 1, more preferably from 1: 2 to 3: 1, for example, 2: 1.
[44] With respect to the total filler and / or pigment content it is especially preferred that the filler and / or the pigment from steps b) and e) is present in an amount of 10% by weight to 95% by weight, preferably 15 % by weight to 90% by weight, more preferably from 20 to 75% by weight, even more preferably from 25% by weight to 67% by weight, especially from 33 to 50% by weight on a dry weight basis of the composite material .
[45] The combination of the gel from step d) with at least one filler and / or an additional pigment from step e) can be carried out (o) only by mixing the combination, for example, using a spatula. In addition, it can be advantageous to mix the components by means of a stirrer with a mounted dissolving disk. Subsequently, the resulting combination can be subjected to water removal. In this regard, generally any commonly used method of removing water known to that person skilled in the art can be used, such as, for example, heat drying, pressure drying, vacuum drying, freeze drying, or drying under the supercritical conditions. The water removal step can be carried out on known devices such as at a filter pressure, for example, as described in the Examples. Generally, other methods that are well known in the field of molding aqueous systems can be applied to obtain the inventive composites.
[46] The use of nanofibrillary cellulose gels as defined above for the production of a compacted composite material is an additional aspect of the invention, in which the gel is combined with at least one filler and / or an additional pigment is the resulting combination is subjected to water removal as described in detail above.
[47] Another aspect of the present invention is the composite material obtained by the process according to the invention, or by using nanofibrillar cellulose gels for the production of the composite material as mentioned.
[48] The composite material can be advantageously used in applications such as plastics, paints, rubbers, concrete, ceramics, panels, supports, sheets, films, coatings and extrusion profiles, adhesives, foods or in wound healing applications and they can readily replace certain materials such as used plastics such as building material, packaging, etc. EXAMPLES OC-GCC material: Omyacarb © 10-AV available from Omya AG; Fine calcium carbonate powder manufactured from high purity, white marble; the average particle size weight d50 is 10 µm as measured by Malvern Mastersizer X.

Pulp: Eucalyptus pulp with 25 ° SR. Gel formation
[49] 120 g of eucalyptus pulp as dry surfaces were cut into pieces and mixed with 5880 g of tap water and the respective amount of OC-GCC (see Table 1) was added. The resulting mixture was stirred for at least 15 minutes using Pendraulik (dissolving disc) at 4000 rpm. The fibrillar content of the formulations was 3% by weight.
[50] The resulting mixtures were subsequently fibrillated in an ultrathin friction crusher (Supermasscolloider by Masuko Sangyo Co. Ltd, Japan (Model MKCA 6-2) in simple steps in a -50 gm slit (dynamic 0 point) with the following presentation: 5 steps at 2500 rpm, 2 steps at 2000 rpm, 2 steps at 1500 rpm, 2 steps at 1000 rpm, 2 steps at 750 rpm, 2 steps at 500 rpm.
[51] The crushing of the stones were silicon carbide with a grain class of 46 (grain size 297 - 420 gm). Table 1: Composition and characteristics of the gel used for Compact formulations
Formulation production
[52] In order to obtain and test the compacts of the nano cellulosic gels, the following formulations for specimen production were produced according to table 2. Table 2: Composition of compact formulations

[53] The gel from sample 1 was mixed with the corresponding amount of additional GCC as mentioned in Table 2 and combined manually with a spatula.
[54] Subsequently, the formulations were placed at a lower filter pressure (Whatman Schleicher & Schuell filter paper, 589/2, white tape; filter pressure: fann filter pressure, 3000 series, fann instrument company, Houston Texas , USA) in such quantities that a final specimen thickness of about 3 mm (calculated using densities) was achieved. A PMMA disk (thickness: 10 mm, diameter: 78 mm (adjustment of the internal diameter of the filter pressure) was placed on top of the formulation, which was again coated with the additional material of the same formulation (around 10-20% in weight of the amount of formulation already present).
[55] The filter pressure was then closed and the following pressure profile was applied: 15 minutes at 1 bar, 120 minutes at 4 bar, 45 minutes at 6 bar.
[56] Subsequently, the “semi-dry” disc (solids content: about 50% by weight) was removed from the filter pressure and cut into five identical rectangles (40 mm x 10 mm). These rectangles were placed between the two filter papers and the two aluminum plates weighed with steel balls (about 3000 g) and dried in an oven at about 80 ° C overnight.
