Abstract:
1. A polycarbonate resin composition, comprising: (A) an aromatic polycarbonate resin mixture comprising a polyorganosiloxane-containing aromatic polycarbonate resin; (B) an acrylonitrile-styrene base resin having a melt flow rate (MFR) of 5 or more at 200° C. and a load of 5 kg; (C) a core-shell type elastomer obtained by polymerizing at least one vinyl base monomer in the presence of a rubber-like polymer obtained from monomers comprising alkyl acrylate, alkyl methacrylate, dimethylsiloxane and a diene base compound; (D) a talc; and (E) a polyfluoroolefin resin; wherein: the aromatic polycarbonate resin mixture (A) is present in an amount of from 60 to 97 mass % based on a total mass of the aromatic polycarbonate resin mixture (A) and the acrylonitrile-styrene base resin (B); the acrylonitrile-styrene base resin (B) is present in an amount of from 3 to 40 mass % based on the total mass of the aromatic polycarbonate resin mixture (A) and the acrylonitrile-styrene base resin (B); the core-shell type elastomer (C) is present in an amount of 1 to 37 mass parts per 100 mass parts of the aromatic polycarbonate resin mixture (A) and the crylonitrile-styrene base resin (B); the talc (D) is present in an amount of from 1 to 20 mass parts per 100 mass parts of the aromatic polycarbonate resin mixture (A) and the acrylonitrile-styrene base resin (B); the polyfluoroolefin resin is present in an amount of from 0.1 to 2 mass parts per 100 mass parts of the aromatic polycarbonate resin mixture (A) and the acrylonitrile-styrene base resin (B); the composition optionally comprises per 100 mass parts of the aromatic polycarbonate resin mixture (A) and the acrylonitrile-styrene base resin (B): the organic alkali metal salt and/or the organic alkali earth metal salt (F) comprises at least one member selected from the group consisting of sulfonic acid alkali metal salts, sulfonic acid alkali earth metal salts, polystyrenesulfonic acid alkali metal salts and polystyrenesulfonic acid alkali earth metal salts; and the composition is free from halogen-based and phosphorous-based flame retardants.
