Title:
POLYPROPYLENE COMPOSITION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/042053
Kind Code:
A1
Abstract:
Disclosed is a polypropylene composition, comprising: 60-85 parts by weight of polypropylene resin, 5-10 parts by weight of high-density polyethylene resin, 5-20 parts by weight of a POE complex formulation flexibilizer, 1-5 parts by weight of graphene, and 3-5 parts by weight of a surface modifier. The POE complex formulation flexibilizer adopted by the present invention maintains the good impact performance of a material while increasing the chemical corrosion-resistant performance thereof; the added surface modifier can reduce the erosion of chemicals to the surface of the material; the added graphene not only increases the intensity of the material, but also has an inhibition effect on chemical corrosion, and moreover, the added graphene enables the material to have a unique metal luster and can conceal defects such as fiddle back figures of an injection molding product. The synergism of the POE complex formulation flexibilizer, the surface modifier, and the graphene makes the polypropylene material composition have excellent chemical-resistant performance, maintain good rigid-tough balance, have good appearance, and be capable of being applied to interior and exterior decoration products of an automobile.
