ポリ塩化ビニル系樹脂成形物の製造方法
Document Type and Number:
Japanese Patent JP6995533
Kind Code:
B2
Abstract:
To provide a method for producing a polyvinyl chloride resin molding capable of obtaining a molding which is reduced in a friction resistance of a surface and has a matte surface.SOLUTION: A method for producing a polyvinyl chloride resin molding includes: (A) a step of preparing a vinyl chloride resin compound obtained by melt-kneading component (a) of a first vinyl chloride resin of 100 pts.mass and component (b) of a plasticizer of 40 pts.mass or more and 100 pts.mass or less; and (B) a step of adding a second vinyl chloride resin to the vinyl chloride resin compound to perform melt-molding, where an average degree P2 of polymerization of the second vinyl chloride resin is 0.5 times or more and 1.9 times or less of an average degree P1 of polymerization of the first vinyl chloride resin, and an amount of the second vinyl chloride resin to be blended is 1 pts.mass or more and 8 pts.mass or less based on 100 pts.mass of the vinyl chloride resin compound.SELECTED DRAWING: None
