を向上させる工夫がなされていなかった。2. Description of the Related Art In order to improve the high-speed tensile properties of a vinyl chloride resin, a predetermined amount of a plasticizer is blended into a soft vinyl chloride resin composition, or a thermoplastic monomer is copolymerized with a vinyl chloride monomer. This has been dealt with by using a resin that has been used. However, a soft vinyl chloride resin composition using a plasticizer cannot be used in applications such as an environment in which the plasticizer is eluted due to migration and the deterioration is severe. Further, even in the case of compositions using various vinyl chloride copolymer resins,
The amount of the thermoplastic monomer component used for the copolymerization is generally smaller than the amount of the vinyl chloride monomer component, and the use of these vinyl chloride copolymer resin compositions alone improves the high-speed tensile properties. In many cases, it is not possible to use a small amount of plasticizer. Even in this case, the usage is limited as in the case of the soft vinyl chloride resin composition. Furthermore, when a soft vinyl chloride resin composition obtained by blending a plasticizer with a vinyl chloride resin is evaluated for high-speed tensile properties in accordance with JIS K-6723, the tensile strength is considerably lower than 11.8 MPa. Rigidity cannot be given to molded products. In the case of a vinyl chloride copolymer resin composition, the tensile strength may be equal to or higher than that of the hard vinyl chloride resin composition in the high-speed tensile evaluation shown in JIS K-6723, but the elongation is a softness in which a plasticizer is blended. It is considerably lower than the vinyl chloride resin composition. Further, a two-component blend of a vinyl chloride resin and NBR or a two-component blend of a vinyl chloride resin composition and a thermoplastic polyurethane elastomer exhibits either high strength or high elongation of high-speed tensile properties. But you can't make them both big. Although knowledge about such a composition of a blend of a vinyl chloride resin and a thermoplastic polymer has been known, methods for evaluating tensile properties differ depending on the application to be used, and thus a device for improving both tensile strength and elongation has been devised. I didn't.

い範囲で適宜選択使用しても差し支えない。The Mooney viscosity is 30 ML 1 + 4 (10
When the temperature is less than 0 ° C., the initial elastic modulus decreases and the same behavior as that of the soft vinyl chloride resin composition containing a plasticizer is exhibited.
Conversely, if the Mooney viscosity is greater than 80 ML 1 + 4 (100 ° C.), there is a problem that the processability deteriorates. The thermoplastic polyurethane elastomer is preferably a polyester-based polyurethane having a Shore A hardness of 70 to 90, preferably 75 to 85. If the Shore A hardness is less than 70, there is a problem that the initial elastic modulus is reduced. Conversely, if the Shore A hardness is more than 85, dispersion in the resin phase becomes poor, and desired physical properties cannot be obtained. Here, the Shore A hardness is a measured value based on a test method of JIS B-7727. In order to obtain the above-mentioned vinyl chloride-based resin composition, a kneaded and pelletized product obtained by the same compounding method as for a normal vinyl chloride-based resin is again extruded into a desired molded product by a molding machine such as an extruder or an injection molding machine. Can be molded. The above-mentioned kneading method for pelletizing is performed by kneading at 150 ° C. to 180 ° C. using a kneader such as a pressure kneader, a coal, or a Banbury mixer. The process for producing pellets of the vinyl chloride resin composition in the present invention is the same as a conventionally known process, and the compounding agent is a conventionally known compounding agent such as a heat stabilizer, a processing aid, a filler, an ultraviolet absorber, A coloring agent, a lubricant and the like are used without any particular limitation. The heat stabilizer is used in an amount of 1 to 7 parts by weight, preferably 2 to 5 parts by weight, based on 100 parts by weight of the vinyl chloride resin. Specifically, for example, commonly used heat stabilizers such as Ba-Zn-based stabilizer, Ca-Zn-based stabilizer, Sn-based stabilizer, Pb-based stabilizer, Mg-Al stabilizer, and hydrotalcite-based stabilizer are used. May be used alone or in combination of two or more. The processing aid is added in an amount of 0 to 10 parts by weight, preferably 1 to 5 parts by weight, based on 100 parts by weight of the vinyl chloride resin. Specific examples include commonly used processing aids such as an MMA-based processing aid containing methyl methacrylate as a main component, and a polyester-based processing aid containing adipic acid as a main component.
More than one species may be used in combination. The filler is 0 to 20 parts by weight, preferably 1 to 1 part by weight, based on 100 parts by weight of the vinyl chloride resin.
0 parts by weight are blended. Specific examples include commonly used fillers such as calcium carbonate, magnesium carbonate, calcium sulfate, magnesium sulfate, and talc, which may be used alone or in combination of two or more. The UV absorber is used in an amount of 0 to 6 parts by weight, preferably 0 to 3 parts by weight, based on 100 parts by weight of the vinyl chloride resin. Specifically, for example, a benzophenone-based ultraviolet absorber, a benzotriazole-based ultraviolet absorber, and a cyanoacrylic-based ultraviolet absorber may be mentioned, and these may be used alone or in combination of two or more. The lubricant is used in an amount of 0 to 10 parts by weight, preferably 0 to 5 parts by weight, based on 100 parts by weight of the vinyl chloride resin. Specific examples include commonly used lubricants such as higher fatty acid metal salts such as calcium stearate, higher alcohols, and polyethylene waxes. These may be used alone or in combination of two or more. Further, a colorant or other thermoplastic resin may be blended, and the type and the amount of addition may be appropriately selected and used depending on the purpose within a range that does not impair the purpose of the present invention.
