Abstract
A flameproof thermoplastic resin composition comprises (A) 100 parts by weight of a thermoplastic resin; (B) about 1 to about 40 parts by weight of a sublimational filler; and (C) about 1 to about 30 parts by weight of a flame retardant. The thermoplastic resin composition can solve the problems of high specific gravity and deterioration of flame retardancy caused by adding a conventional filler.
Claims16
A flameproof thermoplastic resin composition comprising (A) 100 parts by weight of a thermoplastic resin;
- (B) about 1 to about 40 parts by weight of a sublimational filler;
- and (C) about 1 to about 30 parts by weight of a flame retardant.
A method for preparing a flameproof thermoplastic resin composition, the method comprising extruding a thermoplastic resin composition at a temperature of 120 to 280° C., wherein said thermoplastic composition comprises 100 parts by weight of a thermoplastic resin, about 1 to about 40 parts by weight of a sublimational filler, and about 1 to about 30 parts by weight of a flame retardant.
A method for improving flame retardancy comprising adding a sublimational filler which has a sublimation temperature of about 200 to about 500° C. to a flameproof resin comprising a thermoplastic resin and a flame retardant.
