POLYAMIDE RESIN COMPOSITION WITH GOOD REFLECTANCE, IMPACT STRENGTH, HEAT RESISTANCE, AND WATER RESISTANCE, AND METHOD OF PREPARING THE SAME

摘要

PURPOSE: A polyamide resin composition is provided to ensure excellent reflectance, impact strength, heat resistance, and moisture resistance, and to express the change of low reflection reduction rate and yellowness. CONSTITUTION: A polyamide resin composition comprises (A) 100 parts by weight of a polyamide resin, (B) 5-50 parts by weight of titanium dioxide, and (C) 1-20 parts by weight of modified polyolefin. The modified polyolefin is grafted with a monomer with compatibility with the polyamide resin to a polyolefin backbone. The polyamide resin includes aromatic dicarboxylic acids and aliphatic or aliphatic diamines as a repeating unit.
