NON-HALOGEN FLAMEPROOF RESIN COMPOSITION

摘要

A nonhalogenated flame retardant resin composition is provided to improve the stability to fire, environmental friendliness and impact strength and to enhance molding property by reducing the amount of a polyphenylene ether resin. A nonhalogenated flame retardant resin composition comprises 100 parts by weight of a base resin which comprises 80-99 parts by weight of an aromatic vinyl-based resin, and 1-20 parts by weight of a polyphenylene ether resin; and 0.5-30 parts by weight of a cyclic t-butyl phosphonate compound. Preferably the cyclic t-butyl phosphonate compound is represented by the formula 1, wherein R1 and R2 are H, a C1-C6 alkyl group or a C6-C10 aryl group. Preferably the aromatic vinyl-based resin is a polymer of rubber and an aromatic monoalkenyl monomer; and the polyphenylene ether resin is poly(2,6-dimethyl-1,4-phenylene) ether.
