A polypropylene resin composition may include an amount of 40 to 60 wt % of a polypropylene resin, an amount of 1 to 10 wt % of a polyethylene resin, an amount of 10 to 20 wt % of an olefin elastomer, and an amount of 1 to 20 wt % of a reinforcing material wherein all the wt % are based on the total weight of the polypropylene resin composition. Accordingly, a high gloss may be obtained without a coating process and moldability of the polypropylene resin may be obtained. Further provided is a molded article of an interior material or an exterior material of a vehicle manufactured by using the polypropylene resin composition.

Polypropylene resin composition and article prepared therefrom

A polypropylene resin composition includes a base resin, a thermoplastic elastomer, and an inorganic filler. The base resin is a polypropylene-based mixed resin including a first resin, a second resin, a third resin, and a fourth resin. The first resin is a homopolypropylene resin. The second resin, the third resin, and the fourth resin are each a polypropylene-based block copolymer resin. A melt index of the second resin measured at a temperature of 230&#xb0; C. and under a load of 2.16 kg is higher than a melt index of each of the third resin and the fourth resin measured under the same condition. A flexural modulus of the third resin measured in accordance with ASTM D790 is lower than a flexural modulus of the fourth resin measured under the same condition.
