FLAME-RETARDANT POLYAMIDE RESIN COMPOSITION AND MOLDED ARTICLE USING SAME

摘要

The present invention relates to a flame-retardant polyamide resin composition that has excellent properties such as impact strength, flexural modulus, flexural strength, and tensile strength and features little blister owing to little gas-out; and to a molded article using the same. The flame-retardant polyamide resin composition according to the present invention comprises: 40 to 60 wt% of crystalline polyamide resin (A); 10 to 20 wt% of polyphenylene sulfide resin (B); 5 to 15 wt% of a flame retardant including a phosphinic acid metal salt compound (C); 20 to 40 wt% of glass fibers (D); and 0.1 to 0.5 wt% of a phosphite-based antioxidant (E). The flame-retardant polyamide resin composition introduces glass fibers having the surface treated with a urethane-based compound and the phosphite-based oxidant, and thus induces little blister.
