SCRATCH-RESISTANT FLAMEPROOF THERMOPLASTIC RESIN COMPOSITION

摘要

Disclosed herein is a flame retardant thermoplastic resin composition that has superior scratch resistance and mechanical properties, satisfying requirements for the appearance of housing materials resulting from a recent increase in volume of electrical and electronic products, and that contains a phosphorus-based flame-retarding agent, satisfying requirements for fire safety and prevention of environmental problems. The resin composition with scratch resistance comprises a base resin comprising (A) 30 ~ 90 parts by weight of a polycarbonate resin, (B) 10 ~ 50 parts by weight of a polymethylmethacrylate resin and (C) 5 ~ 50 parts by weight of a polyethylene terephthalate-based resin, and (D) 5 ~ 30 parts by weight of a phosphorus-based flame-retarding agent based on 100 parts by weight of the base resin. The composition may further comprise 1 ~ 30 parts by weight of an impact modifier based on 100 parts by weight of the base resin.
