PURPOSE:To obtain a resin compsn. with excellent mechanical characteristics an moldability and a flame retardancy satisfying a specified standard by compounding a flame-retardant, a flame-retardant auxiliary and, in addition, polyetrafluoroethylene and an inorg. filler with a polycarbonate resin and a rubber-contg. thermoplastic resin. CONSTITUTION:100 pts.wt. (hereinbelow described as pts.) resin. compsn. consisting of 20-95wt.% (hereinbelow described as %) polycarbonate resin, 5-80% rubber-contg. thermoplastic resin obtd. by copolymerizing 2 or more vinyl monomers selected from (meth)acrylates, arom. monovinyl compd. and vinyl cyanide compd. in the presence of butadiene rubber, 0-50% thermoplastic resin obtd. by copolymerizing an arom. vinyl monomer and a vinyl cyanide monomer and 0-25% halogenated flame retardant and contg. 0.5-15% halogen atom is compounded with 1-15 pts. flame-retardant auxiliary, 0.02-2.0 pts. fibril-forming polytetrafluoroethylene and 3-100 pts. filler selected from glass beads, glass flakes, talc, diatomaceous earth, etc., to obtain a flame-retardant resin compsn. |
