| 摘 要： | The effects of three foaming accelerators, ZnO, nanometer ZnO, and ZnO/Zn(st)2, on the thermal decomposition property of foaming agents and the ability to create microcellular foam in polypropylene (PP) microcellular foaming plastics are studied. The influence of these accelerators on the microcellular structure of PP microcellular foaming plastics is analyzed by using a thermogravimetry technique. The dispersion of foaming accelerators in resins is observed using scanning electron microscopy. It is shown that the compositing foaming accelerators exhibite a comparatively better dispersion. The properties of different accelerators containing foaming materials are investigated and compared. Compared to those without foaming accelerators, the impact strength of PP microcellular foaming plastics with foaming accelerators is significantly enhanced.
