Lightweight plastic foams are of great significance for saving resources and reducing energy consumption. Foam injection molding (FIM) shows a promising future to provide lightweight and shape‐complex plastic components. However, it is still challenging to produce lightweight and strong polypropylene (PP) foams by FIM due to PP's poor foaming ability. Herein, rubber and talc are employed to improve PP's foaming ability, and hence to enhance PP foam's mechanical properties. Due to the significantly enhanced rheological properties, injection molded PP composite foam exhibits greatly refined and homogenized cellular structure compared with pure PP foam. Thanks to rubber toughening effect and improved cellular morphology, PP/rubber foam shows much higher ductility than pure PP foam. Moreover, talc particles lead to remarkably enhanced rigidity of PP/rubber foams. Thus, lightweight and strong PP/rubber/talc composite foam is achieved with tensile toughness increased by 82.58% and impact strength increased by 106.21%, and they show broad industrial application prospects.

橡胶和滑石粉增强的注射成型强力聚丙烯复合泡沫

轻质塑料泡沫对于节省资源和降低能耗具有重要意义。泡沫注塑成型（FIM）在提供轻巧和形状复杂的塑料部件方面显示出广阔的前景。然而，由于PP的起泡能力差，通过FIM生产轻质且坚固的聚丙烯（PP）泡沫仍然是挑战。在此，橡胶和滑石被用于改善PP的发泡能力，并因此增强PP泡沫的机械性能。由于流变性显着增强，与纯PP泡沫相比，注塑PP复合泡沫显示出极大的细化和均质的泡孔结构。得益于橡胶增韧作用和改善的泡孔形态，PP /橡胶泡沫比纯PP泡沫具有更高的延展性。而且，滑石粉颗粒使PP /橡胶泡沫的刚性显着提高。因此，获得了重量轻，强度高的PP /橡胶/滑石复合泡沫，其拉伸韧性提高了82.58％，冲击强度提高了106.21％，具有广阔的工业应用前景。
