摘　　要：通过改性超细云母粉填充增强微孔发泡聚丙烯（PP）材料，研究结果表明，填充云母与微孔结构间存在明显的协同增强效应，云母填充量为8％～10％（质量分数）时，能有效提高微孔发泡PP的拉伸强度、冲击强度和弯曲强度。The microcellular foam polypropylene was reinforced by micro-fine mica powder. The research results show that the tensile strength and impact toughness and bending strength of microcellular foam polypropylene are improved effectively while mica content reaches 8%～10% （mass fraction）. And there is a apparent synergetic reinforcing effect between microcellular structure and mica powder.
