Abstract
Provided is a vinyl chloride resin composition with which color tone variation caused by molding temperature difference is inhibited. The vinyl chloride resin composition contains a vinyl chloride resin, a plasticizer, a uracil compound, and either or both of acetylacetone and a metal salt of acetylacetone. The vinyl chloride resin composition is preferably used in powder molding.
Claims13
A vinyl chloride resin composition comprising:
- a vinyl chloride resin;
- a plasticizer;
- a uracil compound;
- an acetylacetone, a metal salt of acetylacetone or a combination thereof with a mass ratio of the an acetylacetone and/or the metal salt of acetylacetone to the uracil compound is 1:3 or more;
- and
- a β-diketone other than the acetylacetone and the metal salt of acetylacetone present in an amount of 0.40 parts by mass or more relative to 100 parts by mass of the vinyl chloride;
- wherein the β-diketone other than the acetylacetone and the metal salt of acetylacetone is selected from a group consisting of a) a β-diketone compound that includes a benzoyl group, and b) a blend of a β-diketone compound that includes a benzoyl group and a β-diketone compound that does not include a benzoyl group;
- wherein the plasticizer includes a polyester, a trimellitic acid ester, and an epoxidized soybean oil,
- wherein a content of the plasticizer is 117 parts by mass or more and 200 parts by mass or less relative to 100 parts by mass of the vinyl chloride resin,
- wherein the polyester comprises an adipic acid-based polyester, a sebacic acid-based polyester, a phthalic acid-based polyester, or a combination thereof, wherein a content of the polyester is 110 parts by mass or more and 120 parts by mass or less relative to 100 parts by mass of the vinyl chloride resin,
- wherein a content of the trimellitic acid ester is 5 parts by mass or more and 50 parts by mass or less relative to 100 parts by mass of the vinyl chloride resin, and
- wherein a content of the epoxidized soybean oil is not less than 2 parts by mass and not more than 7 parts by mass relative to 100 parts by mass of the vinyl chloride resin.
