摘　　要：填料在加入到聚合物以前的改性处理可以改善聚合物/填料之间的结合和复合材料的性能。本工作摸索了用锡溶胶、锡溶胶/偶联剂处理硅灰石的合适条件。通过粒度分析和化学分析对锡溶胶的改性效果进行了评价。采用接触角法确定了偶联剂的最佳用量。还分别对用锡溶胶、偶联剂和锡溶胶/偶联剂的硅灰石填充聚丙烯的加工性能和力学性能进行了比较,并用扫描电镜(SEM)观察了断裂面状态。结果表明:锡溶胶、锡溶胶/偶联剂改性硅灰石填充聚丙烯的宏观性能有显著的提高。Optimum condition for modifying wollastonite with sol/coupling agent had been explored. PP filled with the Wollastonite was studied by Particle analysis, chemical analysis and SEM. Thecontact angle, mechanical property and flow property of the product were determined. It was found that not only the properties of the Composite were improved but also the filler content reached to 60%.
