THERMOPLASTIC RESIN COMPOSITION FOR PRODUCING AUTOMOBILE EXTERIOR PART

摘要

Disclosed is a thermoplastic resin composition for producing automobile exterior parts, which comprises the components (A)-(H) described below and has a good balance among fluidity, impact resistance, dimensional stability, rigidity, heat-resistant rigidity, electrical conductivity, coating adhesion and appearance. The thermoplastic resin composition is also excellent in retention stability. Component (A): a polyamide 6 resin having a viscosity of 80-120 ml/g, and a ratio between the terminal carboxyl group concentration and the terminal amino group concentration of 2-6 Component (B): a hydrogenated product of a block copolymer of a vinyl aromatic compound polymer block and a conjugated diene compound polymer block Component (C): a hydrogenated product of a block copolymer of a vinyl aromatic compound polymer block and a conjugated diene compound polymer block, which hydrogenated product is graft-modified with maleic anhydride Component (D): a conductive carbon black Component (E): a talc having an average particle diameter of 0.5-10 µm Component (F): a phosphonite compound Component (G): an ethylene vinyl alcohol resin Component (H): a pentaerythritol phosphite
