Novel polypropylene composite material and preparation method thereof

Abstract

The invention relates to the technical field of polypropylene, and discloses a novel polypropylene composite material. The novel polypropylene composite material comprises, by weight, 50-80 parts of polypropylene, 10-13 parts of glass fibers, 8-12 parts of carbon fiber, 10-15 parts of polytetrafluoroethylene, 6-10 parts of silicon dioxide, 5-8 parts of diboron trioxide, 2-5 parts of an antioxidant, 3-6 parts of a moisture-proof agent, 2-4 parts of a preservative, 5-8 parts of a wear-resistant material, 6-10 parts of a high-temperature-resistant material, 3-6 parts of a flame-retardant material, 3-8 parts of a flexibilizer and 4-7 parts of a heat stabilizer. High-strength materials are added, the high-strength materials comprise the glass fibers, carbon fibers, polytetrafluoroethylene, silicon dioxide and diboron trioxide, and the glass fibers, the carbon fibers, the polytetrafluoroethylene, the silicon dioxide and the diboron trioxide are added into the polypropylene, so that the polypropylene has a high strength, and plastic products obtained by processing the polypropylene composite material have the high strength, and can be applied to some structures or products with large mechanical stress.

Description

technical field [0001] The invention relates to the technical field of polypropylene, in particular to a novel polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene is a thermoplastic resin obtained by polymerizing propylene. It is a white waxy material with a transparent and light appearance. Polypropylene is an inexpensive and widely used plastic that can be processed according to the properties of the finished product. However, the existing polypropylene has poor strength, which leads to the fact that the processed plastic products cannot be used in some structures or products with relatively large mechanical stress. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the existing polypropylene has poor strength, and the processed plastic products cannot be used in some structures or products with relatively large mechanical stress, and a...
