POLYPROPYLENE COMPOSITE MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
A polypropylene composite material, and a preparation method therefor and a use thereof, relating to the field of automotive interior and exterior materials. The polypropylene composite material comprises the following components in parts by weight: 59-90 parts of a polypropylene resin, 5-15 parts of a high-density polyethylene resin, 5-10 parts of a 1-octene-ethylene block copolymer, 5-10 parts of an ethylene-propylene copolymer, 5-15 parts of glass fiber, and 0.05-2 parts of a nucleating agent. The compounding of the 1-octene-ethylene block copolymer and the ethylene-propylene copolymer can improve the bending and cracking resistance of a glass fiber reinforced polypropylene composite resin; additionally, the addition of the high-density polyethylene resin can uniformly disperse the glass fiber in the polypropylene resin, making the polypropylene composite material have a good appearance.
