Description

technical field

[0001] The invention relates to the technical field of new materials, in particular to a polypropylene material used for automobile bumpers, and also relates to a preparation method of the material. 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. Various environmentally friendly polymer composite materials have been widely used in automobiles. Automobile bumpers are mostly made of materials such as polyurethane elastomer and ABS, but the molding process of these materials is complicated and expensive, which increases the cost of automobiles and increases the burden on buyers. The molding process of modified polypropylene material is simple, the cost is relatively low, and it is the best material for automobile bumper. However, the modification process of the existing polypropylene material is complicated, and the impact resist...
