Description

1287060 IX. Description of the invention: [Technical field to which the invention pertains] This is a synthetic resin leather which is used for, for example, automotive interior materials, automobile seats, furniture skin materials, and the like. [Practical Technology] _In the past, as a skin material for a car seat or other chair, a synthetic resin leather was used which was formed on the early surface of the base fabric to form a synthetic tree moon layer made of soft polyvinyl chloride. The base fabric is mainly a double-faced knitted fabric woven from rayon, cotton, polyester, nylon, acrylate, urethane or the like alone or in a blended manner. However, in the past, the double-knit fabric has a tendency to extend in the longitudinal direction to be smaller than the lateral direction, and the tensile strength in the longitudinal direction is larger than that in the lateral direction, because of the use of such a knitted fabric as a car seat. Or the surface material of other chairs, the distortion of the curved surface may occur, or wrinkles, deformation, cracking, etc. caused by the weight of the human body, which is the problem. And 'In order to make the base fabric retain the natural softness and comfort (feel) that is indispensable for the leather, and to make the dressing ratio of the seat or chair after sewing, and the sewing work is good, In the past, the thickness of the double-knit fabric is not thick, and the tensile strength in the longitudinal direction is large, and it is difficult to produce the leather material of the car seat or other chair by using the knit tree leather. It has self-contained softness and comfort, and it has a bad touch. And ', Fang, Zuo Ke # with the operation, is also prone to wrinkles, must be added after the sewing - the use of steam to wrinkle correction work. On the other hand, as a reduction of the difference in the longitudinal and lateral extensions, 1287060, and ί 曰纟 I e S & The method of forming the yarn loop is up and down. However, as far as the synthetic resin leather of the latter is concerned, since it is a single-faced knit and the soil cloth is not thick, it is less leathery as leather. Furthermore, in the case of the synthetic resin leather of the latter, since it is woven from cotton, woven, nylon, a vinyl fiber, etc., it has a small degree of lateral expansion. The transverse tensile strength is large, it is difficult to produce its own (four) softness and comfort performance, as the leather is lacking in quality [invention content] " In the past, the inventors have found that if used, the extension is elastic The yarn is interwoven with the easily stretchable yarn to make the surface: the base fabric can solve the problems caused by the above, and provide a synthetic resin leather with a touch. After inventor's repeated research, it is possible to use a cellulosic fiber alone for the elastic yarn that is not easy to stretch. 10:40 yarns of a kind:::!, as a stretchable yarn, long fiber west '% (domain hair) The 50~_Dani yarn of the processing, silk, thermoplastic elastomer long fiber, and polyamine-based long-distance fiber is preferable. However, after further research, it was found that the above-mentioned long-fiber crimping processed yarn, ..., plastic elastomer long fiber, polyamine-based formic acid long fiber and other yarns, vertical melting point: if the yarn ring made of such yarn In the double-knit fabric, in the longitudinal direction, the transverse direction, and the continuous f: in the case of 'this part is easily melted and ruptured during burning,

^ Shibuya is easy to catch fire. The synthetic resin skin of the base fabric made of such a knitting is difficult to pass the flame retardant specification of the vehicle interior material (F liver % 3〇2, JIS D • 1287060 1 2 0 1 , etc.), and is also difficult to apply to a car seat. on. The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a novel synthetic resin leather which is excellent in not only good in touch but also flame retardant, and the base fabric provided can reduce the gap in the longitudinal direction and the lateral direction. , and maintain a certain thickness, there is no melting and cracking after burning. In order to achieve the above object, the present invention is a synthetic resin leather comprising a base fabric composed of a double-faced knitted fabric and a synthetic resin layer joined to at least one side of the base fabric; characterized in that the base fabric is The first yarn of U ~ 40 yarns (cellulosic fibers alone or blended κ due to the difficulty of stretching thicker and more elastic, as leather can effectively show the texture) and Μ 3〇0 Danny's second yarn ( a long fiber crimped yarn, a thermoplastic elastic yarn, a polyurethane long fiber (a yarn that is easily stretched but has a low melting point), and is formed by the yarn loop formed by the first yarn The double-knit fabric is knitted in such a manner as to surround the V-ring formed by the second yarn, and the yarn loop formed by the second yarn is discontinuous in the longitudinal direction, the lateral direction, and the front surface of the base fabric (the application of the patent scope). According to this configuration, since the first yarn is less likely to be stretched and elastic, the base fabric composed of the double-knit fabric can maintain a certain thickness, and the first yarn is interlaced with the second yarn which is more easily stretched. The double-knit fabric can obtain a base fabric which not only has a certain thickness but also has a small difference in extension between the longitudinal direction and the lateral direction. Further, since the yarn loop of the second yarn is discontinuous in the longitudinal direction, the transverse direction, and the front surface of the base fabric, even if the second yarn is melted due to a fire or the like, the first V adjacent thereto (containing the melting yarn of the cellulose-based fiber) The yarn loops are carbonized to prevent melting or cracking. Therefore, the synthetic resin leather using this base fabric, -1287060, has a small difference in the extension of the longitudinal direction and the lateral direction, and is made by the thickness of the base fabric. Natural softness and comfort', and the texture is good. It can be wrinkled when it has a seat, and it also has a flame retardant property. Yu Changfu: In this case, the so-called high-precision yarn refers to the yarn of the rabbit phenomenon that is lower than the temperature of the bright point. It consists of a thermosetting tree (4). The ratio of yarn has no special limit

:: In the longitudinal and horizontal directions of the base fabric, and there is no continuity in the table; the second brother:: The yarn is continuous. Brother, V. However, if there is too much yarn loop of the first yarn (the ratio of the first yarn is too large in the extension of the longitudinal direction and the lateral direction, the texture is damaged.) Therefore, the first method is ···first sand The ratio of the number of yarns to the second yarn is the yarn loop formed by the cloth and the yarn loop formed by the second yarn in the longitudinal direction, the direction of inspection, and the front and back of the base fabric (the second item of the patent application scope). The result of the first y yarn ν circle and the second yarn yam on the base cloth. ° Ρ and the table are equally arranged, so the above effect can be further improved: in the synthetic resin leather, the synthetic resin layer is not particularly limited, 2= The vinyl chloride resin or the thermoplastic layer used in the synthetic resin leather may be: cloth = a substance composed of other synthetic resins. Synthetic resin synthetic trees _==:: are all set. Also, the base fabric and ^ δ / The packaged resin layer is laminated to form a resin layer, and the foamed synthetic resin layer is foamed to form a foamable synthetic resin 1287060. However, the synthetic resin layer of the synthetic resin leather is as described above. "The top must have a sense of shellfish, so it is generally used in a very soft fit. In the past, due to problems such as waste recycling, it has also been proposed to replace polyvinyl chloride with atactic polypropylene, ethylene vinyl acetate resin, hydrogen styrene-butylene rubber. In particular, the inventors of the present invention have proposed a synthetic resin leather having a suitable synthetic resin layer instead of vinyl chloride, which does not impair the stimulating properties of the acrylic resin leather and has high tear strength. It can solve the disadvantage that the seam which occurs when the seam is used is large and is easy to be split from the seam. The inventors have first proposed that the synthetic resin layer of the synthetic resin leather can be combined with the above-mentioned base fabric by The synergistic effect of the two results in a good synthetic resin leather. That is, one aspect of the synthetic resin leather of the present invention is a thermoplastic having a Shore A hardness of 65 to 9 Å disposed on at least one side of the base fabric. 50~95% by weight of polyurethane ketone and 50~5wt% of mixed resin of Shore A hardness of 5〇~8〇 of acrylic soft resin, and the hardness of the mixed layer is 6 0~8 0. (Apply According to the third aspect of the invention, the synthetic resin leather having the synthetic resin layer has the same flexibility and touch as the conventional soft-f-vinyl chloride leather, and has resilience and cold resistance. It is excellent in surface damage resistance and can be welded by a high-frequency welding machine. In addition, when yr is used for sewing work using a sewing machine, the stitching is not large, and it is not easy to crack from the stitching. By the synergistic effect between the mixed resin layer and the base fabric, it is possible to provide a synthetic resin leather having excellent texture and excellent flame retardancy. ' 1287060 This synthetic resin leather can have the following characteristics The manufacturing method is manufactured. That is, the thermoplastic polyurea having a Shore A hardness of 6 5 to 90 is 50 to 95% by weight and the Shore B hardness is 50 to 80. % is mixed, and if necessary, additives such as flame retardant, plasticizer, lubricant, etc. may be added, and after thorough kneading, it may be formed into a sheet (mixed resin layer) by a calender or an extruder, and then To The base fabric sheet laminated integrally formed. In order to smoothly form the calender, a (meth)acrylic polymer or a calcium carbonate may be blended in the mixed resin. In order to produce the above-mentioned sheet (mixed resin layer), it can be processed by a calender, or a (meth)acrylic polymer can be blended in the mixed resin to adjust the melt tension during the calender processing, so that the calender processing can be smoothly performed. . The (mercapto)acrylic polymer is obtained by copolymerizing, for example, a molecular weight of 500,000 to 5% by weight of methyl methacrylate 5 〇 to 9 〇 and other ethylenically unsaturated monomers copolymerizable therewith. The copolymer of 10,000 is ideal. Other ethylenically unsaturated monomers exemplified herein are, for example, methyl propylene (tetra) vinegar having a carbon number of 2 to 18, acryl vinegar having an alcohol having 2 to 18 carbon atoms, stupid ethylene, and α-methyl styrene. The acrylonitrile, maleic acid, itaconic acid ruthenium ruthenium polymer is matched with 100 parts by weight of the mixed resin, preferably 〇 ir, 2~1 〇 by weight. The share is more ideal. Acrylic: ί soft polyamine-based ester resin or the resin and gelatinous, such as carbon material, oxidation record, U------------------------------------------------------ The machine is like the end of the shell, but it can be lowered to make the processing of the machine more smooth and light. In particular, the use of calcium carbonate is more desirable for the blending of the inorganic material. 10 1287060 The resin of the range of 1 〇〇 θ by weight is preferably in the range of 5 to 2 parts by weight.

As a method of laminating a base fabric and a sheet, for example, a coating of an adhesive on the base fabric is applied to one side of the adhesive, and the laminate is heated and pressurized. Then, it is not soaked, and secondly, it is necessary to perform marble printing, apply a matting treatment agent, and then heat the sheet at 150 to 2 〇rc, and then pressurize it with a squeeze roll. By the above-described winding operation, the base fabric and the sheet are integrated to obtain a synthetic resin leather. As the above-mentioned adhesive, for example, an ethylene-vinyl acetate copolymer-based gum, a polyvinyl chloride paste, a two-liquid type polyurethane, an adhesive, an epoxy-based adhesive or the like can be used. This adhesive is applied to the base fabric surface or to the surface of the material. The synthetic resin leather has a ductility in the longitudinal direction and the transverse direction, and is within a range of 1 〇 25 N/3 cM Å by a modulus of 2% by weight (according to HSK 6772). Moreover, the longitudinal and lateral extensions are on average in the range of 15% to 20 N/3 cm for the 2% modulus (based on jisk), and the difference between the longitudinal and lateral extents is small.

Since the I exhibit is within a moderate range, as described above, the synthetic sapphire leather provided has an excellent texture and has the same or higher quality as the soft polyvinyl chloride leather used in the past. The above-mentioned synthetic resin layer was used as a thermoplastic polyamine-based &L S曰-elastic body layer, and various abrasion resistances were examined. As a result, the general cross-linking reactant in which a polyisocyanate of a crosslinking agent is added to a thermoplastic polyurethane elastomer and heated to carry out a crosslinking reaction loses the thermoplasticity and cannot be formed into a sheet by a calender. Shape, but if the cross-linking reaction is carried out under heating and the cross-linking reactant is dynamically cross-linked, it will not lose 11 • 1287060 thermoplastic 'can be processed into a sheet by calendering, and dynamically cross-linked The wear resistance of the thermoplastic polyamine-based acid ester elastomer can be greatly improved, and the related technology is first proposed. When this thermoplastic polyamino-f-ester elastomer layer is combined with the above-mentioned base fabric, in addition to the above effects, a synthetic resin leather which is excellent in abrasion resistance = excellent Y can be obtained at a low cost. That is, the synthetic resin leather of the present invention is one of the thermoplastic polyurethane layers of the synthetic resin layer, and the polyisocyanate is blended in the plastic polyurethane urethane elastomer. The thermoplastic polyurethane-based elastomer obtained by dynamic hydration and mixing by heating and kneading is formed into a sheet by a calender. (Applicant's scope 4). In the case where the T ratio of the thermoplastic polyurethane elastomer and the polyisocyanate is the same, when the polyisocyanate is methyl bis(4, fluorene-phenylene) di', fL Ϊ夂S, Compared with 1 〇〇 匕 匕 / 孓 孓 1 υ υ 里 如 热塑性 热塑性 热塑性 热塑性 热塑性 热塑性 热塑性 热塑性 热塑性 热塑性 热塑性 热塑性 热塑性 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 ( ( ( ( ( ). A phosphorus-based plasticizer may also be added to the thermoplastic polyurethane-based elastomer layer. The synthetic resin leather to be treated has excellent flame resistance in addition to the above-mentioned flame retardant effect. |The thermal n-based elastomer elastomer made by dynamic crosslinking method has thermal bonding regardless of whether it is cross-linked or not: it can be processed into a sheet by a calendering machine', and it can be easily and inexpensively manufactured. Leather also has the advantage of being able to be recycled separately from the base fabric due to the heat retention of the thermoplastic polyurethane elastomer. Further, the 'inventors' used the above-mentioned synthetic resin layer as a thermoplastic polyurethane elastomer foamed layer and a thermoplastic polyurethane-based elastomer 12 1287060 non-foamed layer, and the foaming property thereof was A variety of abrasion resistances were obtained. As a result, it was found that, in addition to the cross-linking reactants of the above-mentioned (4), the foaming performance was good when the crosslinking agent was blended, and the related art was first proposed. The synthetic resin obtained by sequentially combining the thermoplastic polyamine-based oxime-based elastomer foam layer and the thermoplastic polyurethane-based elastomer non-fabricated layer with the above-mentioned base fabric Resin leather is excellent in foaming properties in addition to the flame retardancy and abrasion resistance described above. ' ^ / that is, the synthetic resin leather of the present invention, the synthetic resin layer is sequentially provided with a thermoplastic polyurethane elastomer foam layer and a thermoplastic polyurethane elastomer In the foamed layer, the thermoplastic polyaminomethacrylate elastomer foam layer is blended with a polyisocyanate and a foaming agent in a thermoplastic polyurethane elastomer and heated and kneaded. The thermoplastic polyurethane elastomer obtained by dynamic crosslinking is formed into a sheet shape by a calender, and then the foaming agent is foamed by a foaming treatment (Patent No. 6 of the patent application). Further, the thermoplastic polyamine-based f-ester elastomer non-foamed layer is a thermoplastic poly-polymer obtained by blending polyisocyanate with a thermoplastic polyurethane elastomer and heating and kneading for dynamic crosslinking. The amine phthalate elastomer is formed into a sheet by a calender (No. 7 of the patent application). The polyisocyanate is preferably a bis(4,1-phenylene) diisocyanate, and the amount is preferably 0.1 to 2 parts by mass based on 100 parts by mass of the thermoplastic polyurethane elastomer. , especially good for 〇·; [~丨· 5 parts by mass (item 8). In the present invention, the base fabric is subjected to a flame-retardant process using a nitrogen-phosphorus-based flame retardant, and the synthetic resin layer preferably contains at least one of a phosphate-based flame retardant and a nitrogen-based flame retardant, 13 1287060 ( Apply for the patent scope item 9). In the case of flame-retardant processing, if the general phosphorus-based flame retardant is used, the above-mentioned flame retardant specifications cannot be passed. The above-mentioned nitrogen-phosphorus-based flame retardant used in the present invention is preferably a flame retardant selected from the group consisting of condensed ammonium phosphate, condensed melamine phosphate, decyl ammonium octaphosphate, and an amine phosphate ester. As a flame retardant contained in the synthetic resin layer, there is concern about the safety of the halogen or the bismuth-based agent, so the safety surface, the cost, the flame retardant effect, and the like are considered to use the phosphate-based flame retardant. Nitrogen-based flame retardants are preferable.

In this way, the base fabric and the synthetic resin are highly flame retardant, and the flame retardant specification (FMVSS 3〇2, D, etc.) of the automobile interior material can be excellent, and it is excellent in flame retardancy. It is a synthetic resin leather that is used as a car interior material and a skin material for car seats. [Embodiment] Hereinafter, the invention of the present invention will be described in detail with reference to the drawings. The synthetic resin leather A shown in Fig. 1(i) is formed on one side of a base fabric and joined to a synthetic resin layer 2. The base fabric i is a double-knit fabric woven by the first yarn 3 and the second yarn 4. The first yarn 3 is composed of cellulose fibers such as cotton, viscose rayon, hemp, copper ammonium UUPra, acetate, or the like, or the cellulose fibers, polyester, and nicotine I. 10 to 40 yarns of a blend of γ 私 两 驮 驮, urethane, etc., which are not easy to extend, thick and elastic, and can impart a predetermined thickness to the artificial resin leather 〇 (〇.9_~U -), and make; resin leather A shows a good texture. Even if one of the above cellulose fibers or blends is used alone, 14 l287〇6〇:: 'If less than 10 yarns, the yarn is too thick and the elongation is small, so that the phase 1 becomes thick and hard. 'The damage and natural softness and comfort are not as good as ^ vice versa. If it exceeds 40 yarns, it will be too thin and inelastic, and it will also damage the natural softness and comfort of cloth 1 . Cellulose-based fibers are carbonized by burning without burning, and are effective in synthesizing the flammability and flame retardancy of resin leather. In order to impart a good texture to the synthetic resin leather A, it is preferred to blend the cellulose with polyester, nylon, acrylic, urethane or the like. When it is desired to improve the combustibility and flame retardancy, it is preferable to use 20% or more of the fiber and the plain fiber. Shidi 2 yarn 4, which is a kind of long-fiber crimped (fleece) processed silk, thermoplastic, elastic long-fiber, and polyurethane long-fiber 5 〇~3 0 0: Ni yarn, It is easy to extend, and the entanglement with the first yarn 3 can reduce the difference between the longitudinal and lateral directions of the base fabric i. Even if it is one of a long fiber crimped yarn, a thermoplastic elastomer long fiber, or a polyurethane long fiber, if it is less than 5 angstroms, it will be too fine to lower the tensile strength, which is not preferable. On the other hand, if more than 3 Danny is too thick, the degree of extension will decrease and it is not ideal. It can be used as a raw material for long-fiber crimping processing yarns, such as polyester, nylon, polypropylene, etc., but in order to maintain elasticity and impart excellent texture to synthetic resin leather, polyester is used (in which Ethylene glycol dicarboxylate is most desirable. On the other hand, if the second yarn 4 contains cellulose fibers, sufficient elongation cannot be obtained, which is not preferable. 15 1287060 _ The base fabric 1 is formed by interlacing the first yarn 3 and the second yarn 4 described above. Further, the moiré 5, the yarn loop 5 formed by the yarn 3 is used to knit the yarn group R 6 formed by the second yarn 4 into a double-knit fabric, and the second yarn 4 is formed. /Circle 6 is woven in the longitudinal, transverse, and discontinuous manners of the base fabric. 2, the yarn ratio of the first yarn 3 to the second yarn 4 is 1: 1, and the yarn loops 5, 5 formed by the first yarn 3 and the yarn loops 6, 6 formed by the second yarn 4, In the longitudinal direction, the lateral direction, and the surface of the base fabric 1, there is an example of weaving. Further, the symbols 5, 6 in the figure represent the yarn loops '5', 6 formed on the surface side of the base fabric 1, and the yarn loops formed on the inner side. Moreover, for the sake of clarity, the yarn loops 5, 5, and 6, 6' in the table have a change in the thickness of the yarns 3 and 4, but are actually equal in thickness. Fig. 3 shows an example in which the yarn ratio of the first yarn 3 to the second yarn 4 is 2:1, and the yarn loops 5, 5 formed by the first yarn 3 are continuously formed in the longitudinal direction of the base fabric 1. 4, the yarn ratio of the first yarn 3 to the second yarn 4 is 3: 1, and the yarn loops 6, 6' formed by the second yarn 4 are formed in every other column in the longitudinal direction and the transverse direction of the base fabric 1. example. The one of the synthetic resin layers 2 may be a mixed resin layer of 50 to 95% by weight of the thermoplastic polyurethane and 50 to 5% by weight of the acrylic soft resin. The thermoplastic polyaminophthalic acid ester used in the present invention is obtained by reacting a diisoxyl ester compound with a compound containing two or more hydroxyl groups. Among them, a polyurethane elastomer 16 1287060 thermoplastic elastomer (TPU) composed of a so-called soft segment and a hard segment composed of a long-chain polyol, a diisocyanate, and a lock elongation agent is preferably used. These are preferably those having a Shore A hardness of 6 5 to 9 Å resin hardness, particularly a resin hardness of 70 to 80. Further, the present invention is based on the value measured by ASTM D 2240 (measuring temperature 23 ° C).

In the synthetic resin leather of the present invention, a polyether-based polyvalent oxime is used for the purpose of physical properties. Further, since the thermoplastic polyaminocarbene which is a raw material of a polyester-based polyol is excellent in aging resistance and calendering workability, it is also desirable from this viewpoint. As a lock elongation agent, such as ethylene glycol, 1, L propanediol, 1,3-propanediol, 1,2-butanediol, L3-butanediol, anthracene, 4-butanediol, 2,3-butane A low molecular weight polyhydric diol or a diamine, water, or the like of an alcohol, a %, or the like can be used.

On the other hand, if the thermoplastic polyurethane exceeds Μ 19 1287060% by weight, the touch will be hard, it is not suitable for use as leather, and when it is processed by a calender, it will cause decomposition of the processing temperature. Decomposition of the above-mentioned mixed resin can improve the softness of the product. And the addition of a plasticizer can reduce the processing temperature of the mixed resin in the calender processing, and thus can inhibit the decomposition of the thermoplastic polyurethane during processing. Moreover, the phosphate ester plasticizer is also flame retardant. At this time, it can be combined with a plasticizer and a flame retardant.

Among them, an aromatic carboxylic acid ester such as ruthenium & L S 曰 or a phthalic acid ester is preferable from the viewpoint of high plasticization efficiency and little bleeding. The compounding amount of the plasticizer is 0 to 50 parts by weight with respect to 100 parts by weight of the mixed resin, and it is preferable to use 325 parts by weight in the middle of the mixed resin. If it is used in a large amount, it may occur if it is moved or oozing, which is not preferred. In the mixed resin layer, the lubricant used in the synthetic resin, the ultraviolet absorber, the light stabilizer, and the antibacterial temple can be further blended. For the lubricant, such as stearic acid #5, Magnesium, zinc, barium and other fat private metal salts, polyethylene wax, stearic acid, olefin di-fatty acid decylamine, etc. can be used. In the case of external absorbent, 2-(2 - (tetra)-5,-methylbenzene ) stupid and 20 1287060 two sigma sitting and other benzotriazole-based ultraviolet absorbers can be used.

The above-mentioned mixed tree slab sheet (synthetic resin layer 2) composed of a mixed resin layer and the base fabric 1 may be an ethyl-vinyl acetate copolymer latex. a polyvinyl chloride paste, a two-liquid polyurethane adhesive, etc. The adhesive 'can be applied to the surface of the mixed resin sheet in addition to the surface of the base fabric. The polypropylene foamed sheet, and the polypropylene foamed sheet and the mixed resin sheet can be joined together, and a layer of a polyurethane primer layer can also be coated on the layer of the polypropylene foamed sheet. Or a primer layer for improving the adhesion of an epoxy resin primer layer, etc. The synthetic resin leather A in this example can be used for interior materials such as automobiles, headrests, covers, visors, and roofs. Etc.), interior interior materials, skin material for self-propelled saddles, furniture ( The material of the bag such as the chair, the sofa, etc., the raincoat, the apron, etc., and when the resin layer (synthetic resin layer 2) is white-coated on both sides of the base fabric 1, it can be used as the material of the elastic container. 21 ί287〇6〇一 and 'The synthetic resin leather A of the present invention, as shown in Fig. 2 to Fig. 4, ^The yarn of the first yarn 3Fig. 5: Shou-Mu, /w _ ,, , First, v 4, the way of encircling the circumstance and the circle β, weaving the longitudinal, transverse and non-continuous performance of the base fabric i, so it also has excellent flame retardancy, as shown in Figure 2, the first yarn 3 and The yarn ratio of the second yarn 4 is 1.1, and the yarn loop 5 of the first yarn and the yarn loop 6 of the second yarn are in the longitudinal direction of the base fabric i, and also the weaving of the father and the father in the table. The difference v in the longitudinal direction and the lateral direction is excellent as a leather, and is excellent in flame retardancy. : The cloth is more ideal for hard-to-burn processing. In the case of the flame-retardant cooling of the base fabric 1 , the dispersion of the nitrogen-phosphorus-based flame retardant attached to the base fabric or the < ', ' two overheat drying, the flame retardant is fixed on the base fabric In this way, the mixed solution is attached to the base fabric by dipping, coating, spraying, or the like as a nitrogen-phosphorus-based flame retardant, and it is preferred to use an amine amine 'condensed acid-filled amine and an amine-based amine. weight! 1 or more flame retardants. In particular, the urethane phosphate water and the fixing property are good. Even if the synthetic resin emulsion or the later-described synthetic resin emulsion is used in combination, a durable and flame-retardant processing liquid having durability can be used: propylene, isopropylene and water can be used. Wait. For the above-mentioned flame-retardant processing t, it is also possible to use a mixture of an n-type flame retardant and a combination of: 'j's gum or nitrogen-based flame retardant and an aqueous solution: by using a synthetic resin emulsion or an aqueous solution, it is possible to promote It is difficult to burn and it is hard to burn, but the flame retardancy will be relatively low. For synthetic resin emulsions or 7/this time, a polymer such as acrylate or methacrylate acrylate 22 1287060, a copolymer of such monomers with other vinyl monomers such as acrylic acid or vinyl acetate, etc., may be used. Copolymer of monomer and vinylene monomer such as ethylene, vinyl urethane, vinyl acetate polymer, polyester, i vinyl rubber resin (solid component) and flame retardant The ratio is such that each part by mass of the synthetic resin is blended with 5 to 100 parts by mass of the flame retardant. Further, in the synthetic resin layer 2, in order to improve the flame retardancy of the synthetic resin leather, a phosphate-based flame retardant may be further added. Phosphate-based flame retardant 3, such as cresyl phosphate, cresyl phenyl phosphate, trimethyl sulphate, chlorinated ~ 2, 6-xylene phosphate, resorcinol phosphate, aromatic A condensed phosphate ester or the like can be used. However, if the molecular weight is less than 350 and its volatility is too low, it is not suitable for use in the interior materials of vehicles. It is preferable to use a molecular weight of 1350 or more. The condensed high molecular weight phosphate is slightly inferior in flame retardancy, and an aromatic phosphate having a molecular weight of about 350 to 500 is preferably used. Further, a nitrogen-based flame retardant may be used in combination. For nitrogen-based flame retardants, such as melamine, monoamine diamine, biuret, melamine, benzoguanamine, etc., can be used. In Fig. 1 (ii), the foamable synthetic resin sheet 1 is interposed between the base fabric 1 and the synthetic resin layer 2, and then the foamed synthetic resin sheet 3 is foamed to form a hair. Foamed synthetic resin leather A. This foaming property δ is a resin sheet 1 which contains the above-mentioned phosphate ester-based flame retardant, and can also be used in combination with a nitrogen-based flame retardant, and the flame retardancy can be effectively improved. _ Next, in the case of the other aspects of the synthetic resin layer 2, the description of the patent application is the same as the fourth and fifth aspects, and the description of the above-mentioned overlapping portions will be omitted. 23 1287060 In this case, 'the thermoplastic polyurethane-based elastomer layer of the W-layer layer 2 is extracted as a synthetic tree, which is based on the plasticity of the ruthenium complex, the urethane elastomer, the polyisocyanate, and the heating and kneading. The post-kinetic kinetic energy & π + ---- thermoplastic polyurethane elastomer is formed into a sheet by a calender. In the case of the above ratio of the thermoplastic polyamino group "夂S曰 elastomer and polyisocyanate, when using methyl (4, 1 phenyl) monoisocyanate as the polyisocyanate, the opposite side, 100 berries The wound thermoplastic polyurethane elastomer is preferably used in an amount of 〇·1 to 2 Å. Further, the thermoplastic polyurethane-based elastomer layer t is more preferably contained as a phosphorus-based plasticizer. The thermoplastic polyurethane-based elastomer layer after dynamic crosslinking, the thermoplastic polyurethane-based elastomer of the raw material is composed of two or more hydroxyl groups of hydrazine diisocyanate. The polycarbamate obtained by the mutual reaction of the compounds is obtained by addition polymerization of a long-chain diol comprising a terminal active hydrogen with a short-chain diol (short chain chain extender) and a diisocyanate, that is, A polyurethane-based thermoplastic elastomer (TPU) composed of a soft segment component and a hard segment component is preferred. These are preferably in the range of hardness of the Shore A hardness of 65 to 9 ,, particularly in the range of resin hardness of 70 to 80. Further, in the present invention, the Shore A hardness is a value measured by ASTM D 2240 (measurement temperature 23. The above-mentioned types can be used for the diisocyanate compound, the long-chain diol, the chain extender, etc. in order to make the above-mentioned polyamine group. The formic acid-based thermoplastic elastomer is dynamically cross-linked. First, a polyisocyanate is added to the above-mentioned polyurethane-based thermoplastic elastomer, and the mixture is uniformly mixed by a blender. The polyisocyanate g is heated and kneaded. In the dynamic crosslinking reaction, in order to maintain good shearing force, the crosslinking reaction is carried out at a temperature of 24 1287060, and the aromatic polycyanic acid vinegar is suitable, especially the methyl bis (4, phenylene) Diisocyanine _ (10) ^ for him to give out toluene diisocyanine ^, because the boiling point of up to 25 ° ° ° too close to the addition of θ using fatty polyisocyanate must increase the crosslinking temperature, will reduce the efficiency of mixing 'Not ideal. 'It is better to adjust the polyisocyanate (4) to the masterbatch (attached to the batch), that is, the liquid polyisocyanate and the synthetic resin such as polyurethane to solidify and granulate. #此,可交交The polyaminocarbamic acid-based thermoplastic elastomer as a raw material is uniformly mixed before the start of the process. Further, the polyisocyanate may be blocked to inhibit the reaction, but in the present invention, the problem is caused by the absence of early crosslinking. Process, and special needs. Compared with polyurethane elastomers, the amount of polyisocyanate is used when using yttrium (4 1- laughing field - field ι / ητ only Hi this support) When the monoisocyanate (mdi) is used as the polyisocyanate, it is preferably a part by mass based on 100 parts by mass of the thermoplastic polyurethane-based elastomer, particularly in terms of abrasion resistance. When recycling is considered, the dosage is preferably 〇·2~〇·6. If the dosage is not 0. 1 part by mass, there is no crosslinking effect. If it exceeds the mass part, the processing property of the calender will be Further, if a polyisocyanate other than methyl bis-phenylene diisocyanate (MDI) is used, it is necessary to consider the number of molecular oxime and oleic acid acetate groups. The mixture of the polyurethane-based thermoplastic elastomer and the polyisocyanate masterbatch is heated and kneaded. #由加热' can accelerate the cross-linking reaction, but it can also carry out the parent-reacting reaction on the east side of the lining. In this way, the polyurethane-based thermoplastic elastomer can be dynamically cross-linked. A For the heating and kneading operation, a high-shear force device with a shifting force or a double-shaft screw type can be used. In this line of heating and kneading, the temperature is 130~20 (rc for 3~1〇 minutes. After heating and kneading, the dynamically crosslinked thermoplastic polyurethane elastomer is placed in a calender. Further, when it is dynamically crosslinked and then cooled and then heat-molded into a sheet form, the workability is lowered, so that it is preferably formed into a sheet without cooling after the dynamic crosslinking reaction. The calender used is used. The machine device is not particularly limited, and may be used in the reverse L-shape, Z-type, or the like. When four calenders of the reverse L-series are used, the light surface temperature is preferably in the range of 14 〇 to 16 〇 ° C. After the calender is pressed out of the sheet of thickness 〇·〇7~〇·5mm, 'cool it for winding. It can be used arbitrarily using a mixing roll or a hot one. Also, the thermoplastic polyurethane carboxylic acid ester after dynamic crosslinking In the case, an acrylic soft resin may be blended as needed. The acrylic soft resin is preferably a polymer having a multilayer structure, that is, a particulate polymer composed of a core-shell type multilayer structure of two or more kinds of acrylic polymers. , Shore A hardness is 65~90' and 65~75 is better. This type of propionic acid-based soft resin maintains flexibility at room temperature, retains bending durability, and has excellent weather resistance. When using acrylic soft resin, its ideal blend ratio [dynamically crosslinked thermoplastic Polyamine phthalate elastomer/acrylic soft resin] is 80:20 to 70:30 by mass ratio. Moreover, it is generally used in a synthetic resin, a lubricant, a UV absorber, and a light stabilizer. Agents, pigments, antibacterial agents, etc., can also be used in the present invention. 26 1287060 can be used together with plasticizers to improve the softness and feel of the product. And 'adding plasticizer can reduce the processing temperature of the calender processing, and therefore It is possible to suppress the decomposition of the heat-treated 1113⁄4 amino phthalate elastomer after dynamic crosslinking. In the case of a plasticizer, a phosphate vinegar such as cresyl phosphate is preferred. The phosphate-based plasticizer also has The flame retardant effect can also be used as a plasticizer and a flame retardant, and the above-mentioned compounding agent can be added together with the masterbatch of the polyurethane-based thermoplastic elastomer and the polyisocyanate. As described above, the formed sheet is laminated on a base fabric with a urethane-based adhesive to form a synthetic resin leather. After lamination, marble printing can be performed on the surface layer as needed, and a gloss adjuster or embossing can be applied. Secondly, in the other aspects of the synthetic resin layer 2, the description of the sorrows of the sixth to eighth items of the patent application is described, and the description of the above-mentioned repeated portions will be omitted. In this example, the 'synthetic resin layer 2' is composed of The thermoplastic polyurethane-based elastomer foam layer and the thermoplastic polyurethane-based elastomer non-foamed layer are sequentially disposed, and the thermoplastic polyurethane-based elastomer foam layer is The thermoplastic polyurethane-based elastomer is added to the thermoplastic polyurethane-based elastomer and the foaming agent is heated and kneaded to form a dynamically cross-linked thermoplastic polyurethane elastomer into a sheet shape by a calender, and then passed through a sheet. Made by foaming treatment. And the above-mentioned thermoplastic polyurethane-based elastomer non-foamed layer is a thermoplastic polyurethane system in which a thermoplastic polyurethane-based elastomer is added to a polyisocyanate by heating and kneading for dynamic crosslinking. The elastomer is formed into a sheet shape by a calender. The above polyisocyanate is a bis(4, fluorene monophenylene)-isocyanate, and the amount of the thermoplastic polyamine-based ester 27 2787060 elastomer is 〇 1 to 2 parts by mass based on the mass parts by mass of the thermoplastic polyamine ester. And especially in the range of 〇·1~1 · 5 quality 1 part is more ideal. Herein, the dynamically crosslinked thermoplastic polyurethane-based elastomer foam layer is formed by calendering a thermoplastic polyurethane-based elastomer which has been dynamically cross-linked and added to a foaming agent. The mechanism is formed into a sheet shape, and the sheet is laminated on the base fabric, and then the foaming agent is foamed by the foaming treatment. After the sheet is formed by the calendering mechanism, even after the foaming process has passed for 2 to 3 days, the state of the bubble chamber is not deteriorated. Since the foaming agent must be sufficiently kneaded in the thermoplastic polyamine-based ester elastomer after dynamic parenting, it is preferred to add it before the above dynamic crosslinking. That is to say, in the thermoplastic polyurethane of the raw material, the polyisocyanate and the foaming agent added with the crosslinking agent are heated and kneaded, and then dynamically crosslinked to obtain foaming by dynamic crosslinking. A thermoplastic polyurethane elastomer is preferred. And when it is placed in a calender to form a sheet, the thermoplastic polyurethane-containing elastomer containing a foaming agent which is dynamically cross-linked by heating and kneading is cooled and then heated and formed into a sheet shape. The workability is lowered, so that it is preferable to form the sheet directly without cooling after the dynamic parent-incubation reaction. The calendering clothes to be used are not particularly limited, and may be used in an inverse L type, a z type, or an L type. When four calenders of reverse L are used, the surface temperature of the rolls is 14 〇 to 6 〇. The range is better. After the sheet having a thickness of 〇 7 to 〇 5 mm is stretched by a calender, it is cooled and wound. A kneading roll or a hot roll can be used arbitrarily. In the case of blowing agents, such as azomethine (ADCA), p, p, oxy bisbenzene sulfonate (0BSH), p-methyl sulfonate (TSH), dinitrate pentamethyltetramine (DpT) can be used. The above may be used in combination of two or more kinds. Foam layer 28 1287060

The sense of insufficiency is insufficient. From the part that reaches the foaming temperature first, it will be foamed in one breath, 1 scoop of the gas chamber, and become a large gas chamber, so on the other hand, on the other hand, the dynamic crosslinking of the present invention has been added to the foaming agent. The thermoplastic polyurethane-based elastomer is placed in a calender and a portion of the unreacted cross-linking agent remains. If the crosslinking reaction is carried out in the vicinity of the foaming temperature set to be higher than il du; μ, the viscosity of the foaming temperature portion will be slightly increased first, and as a result, a uniform and fine foaming chamber can be formed to form A foamed layer of high strength and component. The foaming temperature is higher than the dynamic crosslinking temperature. The degree of enthalpy is better. If the temperature is lower than 20 C, the amount of decomposition of the foaming agent will increase. If the temperature exceeds 5 〇C, the sheet will be thicker. It will be too soft, and the processing of thermoplastic polyurethane-based elastic limbs will start to decompose, and if you use a nitrogen-based flame retardant like carbamide, it will start to decompose. The dynamic crosslinking temperature is 16 〇. When 匸, the temperature can be controlled to about 1 90 by the foaming aid. The layer is laminated on the thermoplastic polyurethane foamed layer after dynamic crosslinking. A thermoplastic polyaminophthalate elastomer of a thermoplastic polyurethane-based elastomer non-foamed layer, which can be obtained by reacting a diisocyanate compound as described above with a compound having two or more hydroxyl groups. An acid ester, which is obtained by a polycondensation reaction of a long-chain diol having a terminal active oxime with a short-chain diol (short chain chain extender) and a diisocyanate, that is, a soft segment component and a hard segment component. Polyurethane thermoplastic 29 1287060 Sexual elasticity (TPU). This cage π, the temple is also the hardness of the hardness of 65 ~ 90 resin, especially the 70 ~ 80 shake &< tree know the hardness range is the most ideal. Especially use this as the raw material as before Thermodynamic polyamine based on the dynamic cross-linking of the seven------the thermoplastic elastomer is a ruthenium. The thermoplastic polyurethane-based elastic system is placed in a calender to form a sheet. A thermoplastic polyurethane foamed layer and/or a wrapper, a plastic polyurethane-based elastomer non-foamed layer. In addition, an acrylic soft resin may be blended as needed. The acrylic acid soft resin is composed of a multilayer structure polymer, that is, a core-shell type multilayer structure.

It is preferred to polymerize the particulate polymer of two or more kinds of acrylic acid, and the Shore A is more preferably 50 80 ' and more preferably 65 to 75. These acrylic soft resins retain flexibility at room temperature, retain bending durability, and have excellent weather resistance. When an acrylic soft resin is used, the desired compounding ratio [thermoplastic polyurethane elastomer after dynamic crosslinking: acrylic soft resin] is 8 〇 : 2 〇 to 70 : 30 by mass ratio. Further, a plasticizer, a lubricant, an ultraviolet absorber, a photosetter, a pigment, an antibacterial agent and the like which are used in combination with a synthetic resin can also be used in the present invention. With plasticizers, it improves the softness and feel of the product. Moreover, the addition of a plasticizer lowers the processing temperature of the calender processing, and also inhibits the decomposition of the dynamically crosslinked thermoplastic polyurethane elastomer during processing. In the case of a plasticizer, it is preferred to use a cresyl phosphate or the like. Phosphate-based plasticizers also have a flame retardant effect and can also be used as a plasticizer and a flame retardant at this time. The above-mentioned compounding agent can be added and mixed in the case of mixing a polyurethane-based thermoplastic elastomer with a polyisocyanate masterbatch _ 30 1287060.丄厂/| ～8π 1夂< has added foaming agent plastic polyurethane elastomer t-field Tiangan... ^Base-based adhesive to layer on the base cloth, pick up the waste The ~ ____ ~ ~ ~ ~ ~ ~ ~ ~ 糸 糸 糸 糸 糸 糸 糸 糸 糸 糸 糸 糸 糸 糸 糸 糸 糸 。 。 。 。 。 : The person should be treated according to the situation.

The tensile strength in the machine direction and the transverse direction was measured by a 20% modulus test (tensile strength at 20% elongation) based on JIS K 6772. For the measurement of softness, the leather after manufacture is touched by hand, and the touch is made with soft polyvinyl chloride leather (100 parts by weight of synthetic resin layer is blended with 100 parts by weight of plasticizer diethyl phthalate). The hexyl ester of the gas-polymerized ethylene composition of leather) was evaluated. 〇 indicates that it has the same feel as soft PVC leather. X indicates that the touch is hard and can not replace the soft polyethylene leather. The evaluation of the expansion state of the suture is the use of each leather with JASO M40 3-83 seam fatigue. The test is based on the baseline and the state of the suture is visually observed. The latter indicated that there was no expansion at the suture, and the X indicated that the suture was dilated, lacking the product 33 l287〇6〇 practicability. ^ In terms of touch, the synthetic resin leather of the examples and the comparative examples was used as a substance, and the polyvinyl chloride, leather (synthetic tT^tr^Ts& TToTt 12 plasticizer diethylhexyl citrate) The gas-gathered ethylene composition leather was compared.
