(57) [Summary] (Solution) [Solution] With respect to 100 parts by weight of a polycarbonate resin (A), 0.01 to 8 parts by weight of a silicone compound (B) and alkali of an aromatic sulfonic acid represented by the following general formula 1 A flame-retardant polycarbonate resin composition comprising 0.01 to 2 parts by weight of a metal salt (C). Formula 1 Am-R- (SO 3 M) n (wherein R is a phenyl or naphthyl group, A is a halogen atom, an alkyl group, an aryl group, a vinyl group, an alkoxy group, an amino group, a methyl ester group and ethyl M represents an alkali metal, a substituent selected from an ester group. When R is a phenyl group, m and n are each 0. When R is a naphthyl group, m and n are 0 to 7 and 1 to 2, respectively. (M + n ≦ 8). [Effect] Since there is no halogen-based flame retardant composed of chlorine, bromine compound or the like, there is no concern about generation of gas containing halogen caused by the flame retardant during combustion. |
