ENVIRONMENTALLY FRIENDLY FLAMEPROOF THERMOPLASTIC RESIN COMPOSITION AND ARTICLES THEREOF

摘要

PURPOSE: An environmental friendly thermoplastic resin composition is provided to have excellent mechanical properties and thermal stability, and improved flowability, thereby having excellent safety against fire. CONSTITUTION: An environmental friendly thermoplastic resin composition comprises an aromatic vinyl-based resin, polyphenylene ether-based resin, boehmite, and alkyl phosphinate metal salt. Te average particle diameter(D_50) of the alkyl phosphinate metal salt is 0.01-10 micron. The weight ratio of the boehmite and alkyl phosphinate metal salt is 9:1-4:6. The average particle diameter of the boehmite(D_50) is 0.01-10 micron. The aromatic vinyl-based resin is a rubber-modified styrene-based resin. The rubber-modified styrene-based resin has 1-30 wt% of rubber with an average rubber diameter of 0.1-3 micron.
