Problems solved by technology

However, since the above-mentioned amine trapping agent is volatile, it cannot prevent the transfer of the tertiary amine to the skin formed by the vinyl chloride resin for a long time, so the discoloration of the skin material caused by the above-mentioned chemical reaction cannot be prevented for a long time, and the heat aging resistance of the skin material is reduced.

Embodiment 1

[0078]In the blending ingredients shown in Table 1, ingredients other than plasticizers (Trimericx N-08 manufactured by Kao Co., Ltd. and PL-200 manufactured by Sage Easter Co., Ltd.) and paste vinyl chloride resin were added to Heng Mix in a Scheer mixer, add a plasticizer when the temperature of the mixture rises to 80°C, and then dry up (dry up, referring to the state where the plasticizer is absorbed by the vinyl chloride resin particles, and the above mixture becomes loose. ), and then add paste vinyl chloride resin as a release agent when the composition is cooled to below 70° C. to prepare a vinyl chloride resin composition for powder molding. Then, heat aging resistance (elongation at break at low temperature at the initial stage and after heat aging) and glossiness (gloss retention ratio of a glass plate) were measured according to the methods described above. The results are shown in Table 1.

Embodiment 2、3 and comparative example 1~4

[0080] The same operation as in Example 1 was carried out except that the blending components were changed as shown in Table 1. The results are shown in Table 1.

Abstract

A vinyl chloride resin composition for forming a powder is configured so as to contain (a) 100 parts by mass of a vinyl chloride resin, (b) 65 to 105 parts by mass of a specific trimellitate plasticizer, and (c) 10 to 50 parts by mass of a specific phthalic acid diester plasticizer, and so that the ratio of the specific phthalic acid diester plasticizer (c) to the total plasticizer content is 5 to 50 by mass percent.

Description

technical field [0001] The present invention relates to: a vinyl chloride resin composition for powder molding, which provides a molded body that has good heat aging resistance even if it is laminated with a foamed polyurethane molded body, and produces a small amount of volatile matter even when heated; A vinyl chloride resin molded body formed by slush molding of a vinyl chloride resin composition powder for body molding; a laminate comprising the above-mentioned vinyl chloride resin molded body and foamed polyurethane molded body. Background technique [0002] The automotive instrument panel has a structure in which a foamed polyurethane layer is provided between a skin made of vinyl chloride resin and a base material. The skin formed of vinyl chloride resin changes color over time, and its heat aging resistance decreases. One of the causes of this discoloration is the chemical transfer of the tertiary amine used as a catalyst when forming the foamed polyurethane layer to...
