Abstract

The invention discloses a terpolymer-reinforced polypropylene, and relates to the technical field of automobile decoration. The terpolymer-reinforced polypropylene is made of the following components:polypropylene resin, talc powder, nano graphene, nano zeolite powder, terpolymer, master batch, hard stearyl, sodium dihydrogen phosphate, magnesium hydroxide, 1,1-bis(tert-butylperoxy)cyclohexane, and plasticizer. The terpolymer-reinforced polypropylene provided by the invention has high strength, soft touch, scratch resistance and dimensional stability, which can meet the requirements of automotive interior strength and touch, and be very suitable for the preparation of large interior parts such as car dashboards and door panels.

Description

Technical field [0001] The invention belongs to the technical field of automobile decoration, and specifically relates to a terpolymer reinforced polypropylene. Background technique [0002] At present, with the rapid development of the automobile industry, people have higher and higher requirements for the cost performance of automobiles, and various environmentally friendly polymer composite materials have been widely used in automobiles. Polypropylene (PP) has the advantages of low density, high cost performance, excellent heat resistance, rigidity, chemical resistance, easy processing and molding and recycling. It has been widely used in automobiles and has become a plastic for automobiles. The variety with the largest consumption and the fastest development. However, PP material has poor heat resistance, low rigidity, low impact toughness, and low surface hardness compared to other materials. Especially after adding talc, it has poor scratch resistance. These defects severe...
