Abstract
An object of the invention is to provide a flame-retardant polycarbonate resin composition which can provide a sliding property of a molding product formed of a flame-retardant resin composition obtained by blending a polycarbonate resin and a styrene resin with a phosphate ester compound and having a good flowability without decreasing an appearance of a molding product. The invention relates to a flame-retardant polycarbonate resin composition including 100 parts by weight of a resin composed of (A) from 60 to 99% by weight of a polycarbonate resin and (B) from 40 to 1% by weight of a styrene resin, (C) from 1 to 30 parts by weight of a phosphate ester compound and (D) from 0.3 to 3 parts by weight of a silicone oil having a viscosity of from 1,000 to 20,000 cs.
