FLAME RETARDANT THERMOPLASTIC RESIN COMPOSITION BASED ON POLYCARBONATE

摘要

PURPOSE: A flame retardant thermoplastic resin composition based on polycarbonate is provided to prevent the generation of stress crack and the generation of liquid impurities by the volatilization of the flame retardant. CONSTITUTION: The flame retardant thermoplastic resin composition comprises: (A) 50 to 95 wt% of a thermoplastic polycarbonate resin containing no halogens; (B) 5 to 50 wt% of a rubber-modified and styrene-containing graft copolymer resin which contains no halogens; (C) 0 to 30 wt% of a styrene-containing copolymer resin which contains no halogens; (D) an alkylated triphenylphosphate consisting of 1 to 20 wt% of a trialkyl phenyl phosphate, 10 to 50 wt% of a dialkyl phenyl monophenyl phosphate, 15 to 60 wt% of a monoalkyl phenyl diphenyl phosphate and less than 2 wt% of triphenyl phosphate; and (E) a fluorinated polyolefin resin, wherein (D) and (E) are used in the amount of 3 to 20 wt% and 0 to 2 wt%, respectively, based on 100 wt% of (A)+(B)+(C).
