摘　　要：采用陶瓷微珠对聚丙烯进行共混改性.对共混试样的力学性能、热性能和流变性能等进行了测试和分析.结果表明陶瓷微珠可明显改善聚丙烯的力学性能和热性能.随着陶瓷微珠用量的增加,复合材料的弯曲性能和耐热性都有很大提高,当其用量达到40份(质量份数)时,复合材料的力学性能最佳.The blends of polypropylene（PP） with ceramic micro-sphere are studied in this paper.The properties of samples are tested and analyzed,which include tensile properties,izod impact strength,flexural properties,vicat softening temperature and rheological property.The results show that ceramic micro-sphere can improve the properties of tensile in different degree;The properties of flexural and heat resistance increase with the increasing of filler amount.When the content of ceramic micro-sphere reaches 40phr,the composite has the optimum mechanical properties.
