Using PP as the base resin, POE is the toughening agent, talcum powder is the reinforcing filler, and the automobile bumper special material with the performance meets the requirements is obtained. The modified PP has ultra high impact strength, its notched impact strength is up to 723 J/m, and it has enhanced softness, excellent heat resistance, low temperature resistance and aging resistance. Based on small bulk polypropylene (PP), it is blended with co-polypropylene (CPP), POE, wollastonite and other additives to produce special materials for bumper and door panels. The analysis showed that the formulation of PP/CPP/POE/wollastonite blending system was reasonable, the process route and parameters were correct. When PP:CPP:POE: wollastonite mass ratio is 45~48:26~29:19~22:4~6, the blending material can fully meet the performance requirements of automobile bumper; when PP:CPP:POE:silicon When the mass ratio of limestone is 45~50:27~29:3~6:17~20, the blending material can fully meet the performance requirements of automotive door panels. The research found that the comprehensive performance of POE modified PP is better than the traditional toughening agent; wollastonite also has a certain toughening function, and some play the role of glass short fiber.
