Embodiment 1

[0053] 100 parts by mass of vinyl chloride-based resin particles (ZEST2000Z manufactured by New Daiichi Salt Bi Co., Ltd.) with an average particle diameter of 124 μm composed of vinyl chloride-based resins with an average degree of polymerization of 2000, and 1 part by mass of antioxidant (IRGANOX1010 manufactured by Ciba Specialty Chemicals Co., Ltd.) , light stabilizer (ADEKA STAB LA-67 manufactured by ADEKA company) 0.2 parts by mass, ultraviolet absorber (TINUVINP manufactured by Ciba Specialty Chemicals company) 0.3 parts by mass, pigment (DAP1050 white manufactured by Dainichi Seika Co., Ltd.) 0.6 parts by mass, pigment (Dainichi Seika Co., Ltd. 3.8 parts by mass of DA PX 1720 (A) black) manufactured by Nissei Chemical Co., Ltd., 0.2 parts by mass of zinc stearate (SZ2000 manufactured by Sakai Chemical Industry Co., Ltd.) were mixed in a Hengol mixer, and when the temperature of the mixture rose to 80°C, The linear ratio of each alkyl group is 100%, the ratio of the alky...

Embodiment 2

[0055] In place of the vinyl chloride resin particles used in Example 1, vinyl chloride resin particles having an average particle diameter of 130 μm (ZEST2500Z manufactured by New Daiichi Salt Bi Co., Ltd.) composed of vinyl chloride resin with an average degree of polymerization of 2500 were used. ; Use each alkyl straight chain rate as 100%, the proportion of the alkyl group with 8 carbon atoms relative to the whole alkyl group is 50 mole %, and the ratio of the alkyl group with 10 carbon atoms with respect to the whole alkyl group is In place of the trimellitate plasticizer used in Example 1, 145 parts by mass of a 50 mol % trimellitate plasticizer (Monocizer W-796 manufactured by Dainippon Ink & Chemicals Co., Ltd.) was used. Except for this, the same operations as in Example 1 were performed to prepare a vinyl chloride-based resin composition for powder molding. The evaluation results are shown in Table 1.

Abstract

Disclosed is a vinyl chloride resin composition for powder molding, which contains 100 parts by mass of vinyl chloride resin particles composed of a vinyl chloride resin having an average polymerization degree of not less than 1500, and 110-150 parts by mass of a specific trimellitate plasticizer. The vinyl chloride resin particles have an average particle diameter of 50-500 [mu]m. The vinyl chloride resin composition for powder molding has excellent powder fluidity and enables formation of a molded body having high thermal aging resistance and cold resistance.

Description

technical field [0001] The present invention relates to a vinyl chloride-based resin composition for powder molding that provides a molded body with good powder fluidity, high heat aging resistance, and high cold resistance; combining the vinyl chloride-based resins for powder molding A vinyl chloride-based resin molded body obtained by powder molding; a laminate formed from the skin of the vinyl chloride-based resin molded body and foamed polyurethane; The finished automobile interior material and the production method of the vinyl chloride-based resin composition for powder molding. Background technique [0002] Conventionally, vinyl chloride-based resin compositions for powder molding have been powder-molded to produce skin materials for automotive interior components such as instrument panels and door trims. An airbag door related to the airbag device for the passenger seat is provided on a part of the instrument panel. Conventionally, the airbag door is molded separat...
