NON-FLAMMABLE STYRENIC RESIN COMPOSITION HAVING GOOD RHEOLOGICAL AND ANTIFLAMMABLE PROPERTIES

摘要

The present invention is to provide a styrenic flame-retardant resin composition having almost no physical property degradation of the resin and excellent fluidity and flame retardancy, the styrene-based flame retardant resin composition of the present invention is (A) aromatic monoalkenyl monomer, vinyl cyan monomer, acrylic acid or 100 parts by weight of a graft copolymer obtained by bulk, suspension or emulsion polymerization of one or more monomers selected from alkyl ester monomers of methacrylic acid with a diene rubber component or an alkyl acrylate rubber component, and (B) tetrabro 0.5 to 30 parts by weight of an organic flame retardant selected from an aliphatic compound such as brominated epoxy resin or chlorinated polyethylene resin or vinyl chloride resin, which is a diglycidyl ether polymer of mobisphenol A or tetrabromobisphenol A, and (C) decabromodiphenyl 1 to 20 parts by weight of an auxiliary flame retardant selected from ether and octabromodiphenyl ether, D) antimony trioxide is characterized in that consisting of 1 to 10 parts by weight.
