摘　　要：考察了硅藻土粒径和含量对填充聚丙烯复合材料的拉伸性能的影响。结果表明,当硅藻土体积分数时,复合材料的拉伸强度和断裂强度都有所下降,然后,两者均有轻微的提高;除个别测量点外,复合材料的断裂伸长率随着的增加而明显增大;当时,硅藻土粒径为7μm的填充体系的拉伸强度和拉伸断裂强度最高。The effects of diatomite size and content on the tensile properties of the filled polypropylene composites are investigated. The results show that tensile strength and tensile fracture strength of the composites somewhat decrease when Фf 〈 5%, and then increase slightly. The tensile elongation at break of the composites obviously increases with an increase of Фf except for individual data point. When Фf = 10%, the tensile strength and tensile fracture strength of PPI diatomite with particle diameter of 7μm are the highest in these composite systems.
