Abstract

The invention discloses a temperature-resistant and wear-resistant modified polypropylene composite material. The polypropylene composite material comprises the following components in parts by weight: 65-75 parts of polypropylene resin, 10-20 parts of nanoscale polytetrafluoroethylene ultrafine powder (mineral filler), 5-12 parts of toughening agents, 8-15 parts of wear resistant fillers (wear resistant agents) and 0.2-2 parts of auxiliaries. The polypropylene composite material has the advantages and beneficial effects that by adding the nanoscale polytetrafluoroethylene ultrafine powder and the wear resistant fillers to the polypropylene resin, various physical and mechanical properties of the material are basically not affected while the wear resistance of the material is ensured; the obtained material has high surface gloss and has better impact resistance and strength.

Description

Technical field [0001] The invention relates to the field of plastics, in particular to a temperature-resistant and wear-resistant modified polypropylene composite material. Background technique [0002] Polypropylene has good physical, mechanical, chemical, and easy-to-process properties. It is also lightweight, inexpensive, and easy to recycle, so it is widely used in automotive interior and exterior trim parts. However, the wear resistance of polypropylene material is poor. Some parts that are susceptible to constant friction from the outside, such as brake lamp housings, horn covers, etc., will be damaged due to friction, which directly affects the appearance of the car and seriously affects it. In the application of automotive trim parts, polypropylene materials need to be improved to meet the requirements of product wear resistance. [0003] Commonly used wear-resistant additives in the prior art include molybdenum disulfide, polytetrafluoroethylene, amides, and silicone mat...
