Title:
VINYL CHLORIDE-BASED RESIN COMPOSITION FOR POWDER MOLDING, AND VINYL CHLORIDE-BASED RESIN-MOLDED BODY AND LAMINATE
Document Type and Number:
WIPO Patent Application WO/2019/087534
Kind Code:
A1
Abstract:
The present invention pertains to a vinyl chloride-based resin composition for powder molding, the resin composition containing a vinyl chloride-based resin (A) having an average particle size of 50-500 μm and an average degree of polymerization of at least 1350, a vinyl chloride-based resin (B) having an average particle size of at least 0.01 μm and less than 50 μm, a plasticizer, and a phosphate ester, wherein the phosphate ester is polyoxyalkylene alkyl phosphate ester, the blending amount of the vinyl chloride-based resin (B) is 5-40 parts by mass, the blending amount of the plasticizer is 120-150 parts by mass, and the blending amount of the polyoxyalkylene alkyl phosphate ester is 0.1-3.0 parts by mass with respect to 100 parts by mass of the vinyl chloride-based resin (A). As a result, a vinyl chloride-based resin composition for powder molding, and a vinyl chloride-based resin molded body and laminate are provided, the resin composition having good heat aging resistance and high adhesion to a foamed polyurethane layer, enabling easy separation of a mold from a slush molding die, and being capable of producing a molded body having reduced odor.
