Abstract

Disclosed is a vinyl chloride-based resin composition having excellent weather resistance, coloration resistance, and thermal stability as well as excellent transparency, and a molded article using this vinyl chloride-based resin composition. Specifically, the vinyl chloride-based resin composition contains a vinyl chloride-based resin in an amount of 100 parts by mass, an organic acid zinc salt as a component (A) in an amount of 0.01 to 10.0 parts by mass, a β-diketone compound as a component (B) in an amount of 0.01 to 10.0 parts by mass, and one or more triazine-based compounds as a component (C) represented by Formula (1) in an amount of 0.01 to 20.0 parts by mass. (In Formula (1), R 1 to R 3 represent a linear or branched alkyl group having 1 to 12 carbon atoms or the like, and R 4 to R 6 represent an alkyl group having 1 to 8 carbon atoms or the like.)

First claim

1 . A vinyl chloride-based resin composition comprising:
a vinyl chloride-based resin in an amount of 100 parts by mass; an organic acid zinc salt as a component (A) in an amount of 0.01 to 10.0 parts by mass; a β-diketone compound as a component (B) in an amount of 0.01 to 10.0 parts by mass; and one or more triazine-based compounds as a component (C) in an amount of 0.01 to 20.0 parts by mass, the triazine-based compounds being represented by Formula (1):

wherein
R 1 to R 3 are optionally the same or different and represent a linear or branched alkyl group having 1 to 12 carbon atoms, a cycloalkyl group having 3 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, an aryl group having 6 to 18 carbon atoms, an alkylaryl group having 7 to 18 carbon atoms, or an arylalkyl group having 7 to 18 carbon atoms,
the alkyl group, cycloalkyl group, alkenyl group, aryl group, alkylaryl group, or arylalkyl group is optionally substituted with a hydroxy group, a halogen atom, an alkyl group having 1 to 12 carbon atoms, or an alkoxy group having 1 to 12 carbon atoms, or interrupted by an oxygen atom, a sulfur atom, a carbonyl group, an ester group, an amide group, or an imino group,
the substitutions and interruptions are optionally used in combination; and
R 4 to R 6 are optionally the same or different and represent an alkyl group having 1 to 8 carbon atoms or an alkenyl group having 2 to 8 carbon atoms.

2 . The vinyl chloride-based resin composition according to claim 1 , wherein the triazine-based compounds represented by Formula (1) are triazine-based compounds represented by Formula (2):

wherein R 7 to R 9 are optionally the same or different and represent a linear or branched alkyl group having 1 to 12 carbon atoms, wherein the alkyl group is optionally substituted with a hydroxy group, a halogen atom, or an alkoxy group having 1 to 12 carbon atoms, or interrupted by an oxygen atom, a sulfur atom, a carbonyl group, an ester group, an amide group, or an imino group.

3 . The vinyl chloride-based resin stabilizer composition according to claim 1 , further comprising a hydrotalcite compound as a component (D) in an amount of 0.01 to 10.0 parts by mass.

4 . The vinyl chloride-based resin composition according to claim 1 , which is to be used in transparent products.

5 . A molded article made of the vinyl chloride-based resin composition according to claim 1 .

6 . The vinyl chloride-based resin stabilizer composition according to claim 2 , further comprising a hydrotalcite compound as a component (D) in an amount of 0.01 to 10.0 parts by mass.

7 . The vinyl chloride-based resin composition according to claim 2 , which is to be used in transparent products.

8 . The vinyl chloride-based resin composition according to claim 3 , which is to be used in transparent products.

9 . The vinyl chloride-based resin composition according to claim 6 , which is to be used in transparent products.

10 . A molded article made of the vinyl chloride-based resin composition according to claim 2 .

11 . A molded article made of the vinyl chloride-based resin composition according to claim 3 .

12 . A molded article made of the vinyl chloride-based resin composition according to claim 4 .

13 . A molded article made of the vinyl chloride-based resin composition according to claim 6 .

14 . A molded article made of the vinyl chloride-based resin composition according to claim 7 .

15 . A molded article made of the vinyl chloride-based resin composition according to claim 8 .

16 . A molded article made of the vinyl chloride-based resin composition according to claim 9 .
