Abstract

The present invention relates to a polypropylene material with high strength and good moldability. The polypropylene material is characterized by comprising the following components in part by weight: 56.2-60 parts of polypropylene, 30-40 parts of talcum powder, 22-26 parts of glass fibers, 2-4 parts of a flexibilizer, 0.2-0.4 part of a coupling agent, 0.2-0.5 part of a lubricant, 0.1-1.0 part of a heat stabilizer DSTP, 0.1-1.0 part of a heat stabilizer 3114 and 0.1-0.5 part of a heat stabilizer 618. Compared with the prior art, the polypropylene material according to the present invention has higher mechanical strength and besides, is easy to mold, the size stability is substantially improved, and the combination property is excellent.

Description

technical field [0001] The invention relates to a polypropylene material, in particular to a polypropylene material with high strength and good formability. Background technique [0002] In recent years, due to the rapid development of engineering modification technology of polypropylene materials, its application in the automotive field has become more and more extensive. However, as an important part of engineered polypropylene materials in the automotive field, automotive bumpers, various automotive interior parts, and instrument panels made of engineered polypropylene materials, although their performance in all aspects Both of them can meet the corresponding requirements, but it is difficult to meet the two requirements of high strength and good formability at the same time. This is because high strength means high impact, while formability is determined by fluidity, and impact and fluidity are often contradictory. [0003] Therefore, how to solve the deficiencies in ...
