Abstract

The invention discloses a polypropylene material with high impact strength and used for automobiles. The polypropylene material is prepared from raw materials in parts by weight as follows: 80-100 parts of polypropylene, 6-14 parts of chloroprene rubber, 10-20 parts of chlorosulfonated polyethylene, 2-4 parts of a crosslinking agent, 55-65 parts of a filling reinforcing agent, 2-4 parts of a titanate coupling agent, 2-4 parts of pine tar, 2-4 parts of an anti-aging agent and 2-4 parts of a lubricant. The filling reinforcing agent is prepared from, in parts by weight as follows: 20-30 parts ofa bentonite compound, 6-14 parts of glass fiber, 10-16 parts of sepiolite powder and 8-12 parts of talc powder. The bentonite compound is prepared with the following process: N-dehydroabietic acrylamide, nano bentonite and epoxidized soybean oil acrylate are mixed, heating and stirring are performed, 1,1-bis-(tert-butylperoxy)cyclohexane is added, the mixture is stirred continuously, heating and stirring are performed, and the bentonite compound is obtained.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a polypropylene material with high impact strength for automobiles. Background technique [0002] Although there are many types of plastics used in automobiles, polypropylene plastics account for a large proportion. Polypropylene plastic has the advantages of low density, low price, non-toxicity, excellent corrosion resistance, easy processing and molding, and has good mechanical properties, especially suitable for application in the automotive field. However, polypropylene plastic has the disadvantage of poor impact strength, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a polypropylene material with high impact strength for automobiles, which has high hardness, not only thermal stability, but also excellent tensile strength and toughness, and at t...
