PURPOSE: A thermoplastic acrylonitrile-butadiene-styrene-based copolymer flame retardant resin composition is provided, to improve the heat resistance with maintaining favorable flame retardancy and mechanical properties. CONSTITUTION: The thermoplastic acrylonitrile-butadiene-styrene-based copolymer resin composition comprises 100 parts by weight of a thermoplastic acrylonitrile-butadiene-styrene-based copolymer resin which comprises 5-40 wt% of acrylonitrile, 5-40 wt% of butadiene rubber and 20-70 wt% of styrene and whose SAN resin comprises 60-76 wt% of styrene and 24-40 wt% of acrylonitrile and which has a weight average molecular weight of 120,000-200,000; 5-30 parts by weight of a halogen-based compound as a flame retardant; 1-15 parts by weight of antimony trioxide as a flame retardancy aid; and 0.05-10 parts by weight of an aluminosilicate-based inorganic compound as a heat stabilizer. Preferably the composition comprises further 0.05-5 parts by weight of a tin maleate-based compound, 0.05-2 parts by weight of a fluorine-based compound, and/or 1-10 parts by weight of a chlorine-based compound. |
