摘要： A polypropylene composite resin composition and an automotive interior part molded using the polypropylene composite resin composition are provided herein. The polypropylene composite resin composition contains: (a) an easily injection moldable polypropylene polymer, (b) a thermoplastic elastomer for improving impact resistance, (c) a platy inorganic filler surface-treated with an organosilane having affinity for a phytoncide, (d) a phytoncide having deodorizing capability and aromaticity, (e) a processing oil preventing pyrolysis of the phytoncide, and (f) a surfactant for improving the compatibility between the base resin and the phytoncide at specific compositional ratios. The automotive interior part molded using the polypropylene composite resin composition disclosed herein provides a pleasant environment for drivers by removing the offensive odor from volatile organic compounds (VOCs), etc. and maintaining the intrinsic scent of the phytoncide for a long time.
