Document Type and Number:
WIPO Patent Application WO/2024/066972
Kind Code:
A1
Abstract:
Disclosed are a high-primer painting rate polypropylene material, a preparation method therefor, and use thereof. The high-primer painting rate polypropylene material comprises the following components in parts by weight: 55-85 parts of polypropylene, 5-20 parts of an ethylene-octene random copolymer, 0.3-1 parts of niobium diselenide treated on the surface of vinyltriethoxysilane, 10-25 parts of a filler, 0.1-0.3 parts of a lubricant, and 0.1-0.4 parts of an antioxidant. According to the present invention, the polypropylene with a specific melt index is used, thereby guaranteeing that the material has basic fluidity and processability; on the basis, the ethylene-octene random copolymer with a specific melt index and the niobium diselenide treated on the surface of vinyltriethoxysilane are added, and jointly act to improve the painting rate of polypropylene and the impact strength and the peel strength of a notch of a cantilever beam, such that the spraying cost and the environment-friendly pressure can be greatly reduced, and the material has good comprehensive performance and is suitable for parts with a high polypropylene paint spraying requirement.
