FLAME RETARDANT THERMOPLASTIC RESIN COMPOSITION WITH GOOD THERMAL STABILITY AND EXCELLENT PRODUCTIVITY

摘要

A flame-retardant thermoplastic resin composition is provided to improve processability and thermal stability while maintaining impact resistance and fire retardancy and to be suitable for the molding of large-sized products. A flame-retardant thermoplastic resin composition with excellent thermal stability and workability comprises (A) a styrene-based polymer 30~99 weight% including an epoxy group; (B) polyester resin 1~70 weight%; based on (A) + (B) of 100.0 parts by weight, (C) a brome-containing flame retardant 3~20 parts by weight; and (D) an antimony 0.1~6 parts by weight surface-modified with a silane compound. The styrene-based polymer(A) consists of (A1) an epoxy group-containing vinyl copolymer 5~100 weight% and (A2) a rubber-reinforced styrene-based copolymer resin 0~95 weight%.
