The invention discloses a lightweight PP modified material for an automobile bumper. The modified material is prepared from the following raw materials in parts by mass: 80-120 parts of a resin raw material; 5-20 parts of a filling agent; 10 to 25 parts of a toughening agent; 0.5 to 4 parts of a lubricant; 0.4 to 2 parts of an antioxidant; 0.3 to 1.5 parts of a cross-linking agent; the resin raw material is a recycled PP T30S polypropylene resin reworked material subjected to acid pickling treatment, and the filling agent is calcium carbonate with the particle size of 0.1-0.5 mu m; the modified material is prepared by mixing a resin raw material with other auxiliaries in proportion and then adding the mixture into a twin-screw extruder for extrusion granulation. The light-weight PP modified material for the automobile bumper is prepared by recovering and regenerating the polypropylene raw material through specific processing and modification processes, has the advantages of impact resistance, low temperature resistance, chemical resistance, light weight, recyclability and the like, and not only ensures the material performance, but also improves the production efficiency by recovering and regenerating the polypropylene raw material and combining with a modification processing flow. And the cost is effectively reduced, and the green and environment-friendly development concept is embodied.

    本发明公开了一种汽车保险杠用轻量化PP改性材料,改性材料由下列原料按质量份组成:树脂原料80~120份;填充剂5~20份;增韧剂10~25份;润滑剂0.5~4份;抗氧剂0.4~2份;交联剂0.3~1.5份;树脂原料为经过酸洗处理的回收PP T30S聚丙烯树脂再生料,且填充剂为颗粒粒径0.1~0.5μm的碳酸钙;改性材料通过将树脂原料与其他助剂按比例混合后加入双螺杆挤出机中挤出造粒。该汽车保险杠用轻量化PP改性材料通过回收再生聚丙烯原料,经过特定的加工和改性工艺制备,具备耐冲击性、耐低温性、耐化学性,以及轻量化和可循环利用等优点,通过回收再生聚丙烯原料并结合改性加工流程,不仅保证了材料性能,还有效降低了成本,体现了绿色环保的发展理念。
