Abstract
A reinforced thermoplastic resin composition comprising specific amounts of: a main resin component (C) comprising 50 to 100% by weight of a polycarbonate resin (A) and 0 to 50% by weight of a graft copolymer (B) obtained by polymerizing an aromatic alkenyl compound monomer (a) and a vinyl cyanide compound monomer (b) in the presence of a rubber polymer (B1); a grass fiber (D); a glycidyl ether unit-containing polymer (E) containing glycidyl ether units and having a weight average molecular weight of 3,800 to 60,000; a phosphoric acid ester-based flame retardant (F); and an organomodified siloxane (G).
Claims17
A reinforced thermoplastic resin composition comprising:
- a main resin component (C) comprising 50 to 95% by weight of a polycarbonate resin (A) and 5 to 50% by weight of a graft copolymer (B) obtained by polymerizing an aromatic alkenyl compound monomer (a) and a vinyl cyanide compound monomer (b) in the presence of an ethylene-propylene-nonconjugated diene rubber (B1), provided that a total amount of the polycarbonate resin (A) and the graft copolymer (B) is 100% by weight;
- a glass fiber (D);
- a glycidyl ether unit-containing polymer (E) containing glycidyl ether units and having a weight average molecular weight of 3,800 to 60,000, provided that the graft copolymer (B) is excluded from the glycidyl ether unit-containing polymer (E);
- a phosphoric acid ester-based flame retardant (F);
- and
- an organomodified siloxane (G), which is a compound in which an organomodified siloxane is chemically bonded with a polyolefin or a polyamide, or a mixture of an organomodified siloxane with a polyolefin or a polyamide,
- wherein:
- the amount of the glass fiber (D) is 10 to 50% by weight, based on the total weight of the main resin component (C), the glass fiber (D), the glycidyl ether unit-containing polymer (E), the phosphoric acid ester-based flame-retardant (F), and the organomodified siloxane (G), the total weight being 100% by weight,
- the amount of the glycidyl ether unit-containing polymer (E) is 1 to 10 parts by weight, relative to 100 parts by weight of the main resin component (C),
- the amount of the phosphoric acid ester-based flame retardant (F) is 1 to 30 parts by weight, relative to 100 parts by weight of the main resin component (C), and
- the amount of the organomodified siloxane (G) is 1 to 5 parts by weight, relative to 100 parts by weight of the main resin component (C).
