A polypropylene resin composition, particularly, an olefin-based polypropylene resin composition includes: about 50 to 70% by weight of a high crystalline polypropylene; about 10 to 20% by weight of a reactor made thermoplastic polyolefin (RTPO) polypropylene; about 5 to 20% by weight of an inorganic filler; about 10 to 20% by weight of a rubber elastomer; and about 3% by weight or less of a slip agent, based on the total weight of the composition. The composition provides excellent physical properties such as high strength and impact resistance, and thus superior resistance to damage, and shows low gloss characteristics and excellent fluidity. The polypropylene resin composition is used as interior and exterior materials for vehicles.

Polypropylene resin composition and interior and exterior materials for vehicles using the same

Disclosed are a polyolefin-based resin composition having excellent scratch resistance and low glossiness, a preparation method thereof, and automobile interior and exterior materials fabricated therefrom. The polyolefin-based resin composition comprises about 56 to 97% by weight of a polypropylene block copolymer resin, about 1 to 9% by weight of a thermoplastic elastomer rubber, about 1 to 30% by weight of an inorganic filler, and about 1 to 5% by weight of a fluoroacrylamide-based copolymer based on a total weight of the composition.
