Abstract

A vinyl chloride resin composition for powder molding contains 100 parts by mass of (a) a vinyl chloride resin, 65 to 105 parts by mass of (b) a specific trimellitate plasticizer, and 10 to 50 parts by mass of (c) a specific diester phthalate plasticizer. A mixture ratio of (c) the specific diester phthalate plasticizer to whole plasticizers is in a range of 5 to 50 percents by mass.

Claims

1. A vinyl chloride resin composition for powder molding, comprising:

100 parts by mass of (a) a vinyl chloride resin;

65 to 105 parts by mass of (b) a trimellitate plasticizer represented by formula (1); and

10 to 50 parts by mass of (c) a diester phthalate plasticizer represented by formula (2),

a mixture ratio of (c) the diester phthalate plasticizer represented by formula (2), to whole plasticizers being in a range of 5 to 50 percents by mass,

2. The vinyl chloride resin composition for powder molding as set forth in claim 1, being to be subjected to powder slush molding.

3. A vinyl chloride resin molded article being obtained by subjecting to powder slush molding a vinyl chloride resin composition for powder molding as set forth in claim 1.

4. The vinyl chloride resin molded article as set forth in claim 3, being an automobile instrument panel surface.

5. A laminate, in which a polyurethane foam molded article and a vinyl chloride resin molded article as set forth in claim 3 are stacked.

6. The laminate as set forth in claim 5, being a laminate for use in an automobile instrument panel.

7. A vinyl chloride resin molded article being obtained by subjecting to powder slush molding a vinyl chloride resin composition for powder molding as set forth in claim 2.

8. The vinyl chloride resin molded article as set forth in claim 7, being an automobile instrument panel surface.

9. A laminate, in which a polyurethane foam molded article and a vinyl chloride resin molded article as set forth in claim 4 are stacked.

10. The laminate as set forth in claim 9, being a laminate for use in an automobile instrument panel.
