HALOGEN-FREE FLAMEPROOF STYRENIC RESIN COMPOSITION

摘要

A nonhalogenated flame retardant styrene-based resin composition is provided to obtain excellent flame retardancy without using a harmful halogen-based flame retardant. A styrene-based resin composition comprises 100 parts by weight of a base resin which comprises 50-90 parts by weight of a styrene-based resin, and 10-50 parts by weight of a polyphenylene ether resin; 0.1-50 parts by weight of a phosphorus triazine compound represented by the formula 1; and 0.1-30 parts by weight of at least one phosphorus-based compound selected from the group consisting of an alkyl phosphinic acid metal salt, an aromatic phosphoric acid compound and a phosphazene compound.
