Flame-retardant thermoplastic resin composition

摘要

The present invention relates to a flame-retardant thermoplastic resin composition comprising the following components (A) to (D): (A) 50 to 80 parts by weight of an aromatic polycarbonate resin; (B) 5 to 40 parts by weight of a rubber-reinforced thermoplastic resin prepared by graft-polymerizing monomer components comprising an aromatic vinyl monomer, a vinylcyanide monomer and optionally other copolymerizable vinyl-based monomers, with a rubber polymer, the amount of said vinylcyanide monomer used being not less than 0.5 % by weight and less than 5 % by weight based on the total weight of said monomer components; (C) 5 to 30 parts by weight of phosphate represented by the formula (I): <CHEM> wherein R<1> to R<3> are the same or different and are independently an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms; and n is 0 or 1, the total amount of the (A), (B) and (C) components being 100 parts by weight; and (D) 0.02 to 3 parts by weight of polytetrafluoroethylene based on the total weight of the (A), (B) and (C) components.
