摘　　要：通过铝酸酯偶联剂对硅藻土进行改性,以不同含量的硅藻土与聚丙烯熔融共混,制备出硅藻土/聚丙烯复合材料。对比研究了铝酸酯偶联剂与硅烷偶联剂对硅藻土改性效果,观察不同偶联剂及其用量和硅藻土含量对硅藻土/聚丙烯复合材料的组织形貌和拉伸性能影响。结果表明,铝酸酯偶联剂和硅烷偶联剂都有改性效果,且铝酸酯偶联剂的改性效果明显优于硅烷偶联剂,当铝酸酯偶联剂用量为1%时,与硅烷改性复合材料相比延伸率提高了121.60%,断裂强度提高了64.05%。Aluminum coupling agent is used for Diatomite modification.The Diatomite with different content is melt and mixed with polypropylene to prepare Diatomite/polypropylene composites.The modification effects of both the aluminum coupling agent and silane agent on Diatomite are compared to study how the contents of agent and diatomite influence the morphology and tensile properties of the composites.Results show that both agents has the modification effects on Diatomite but the aluminum agent is better than silane.When the content of aluminum is 1%,the elongation of the composites increases 121.60% and the strength is upgraded to 64.05%.
