摘要
本文研究了新型无机填料—膨润土对聚丙烯（ＰＰ）的填充行为（力学性能、熔融指数、密度等），着重考查了用硬酯酸进行表面改性后的填料粒径，填充量对复合材料的物理力学性能的影响；并通过ＤＳＣ、偏光显微镜、ＳＥＭ观察分析了填充体系的微观、亚微观结构。
The filling behavior of bentonite to PP(including mechanic properties M1,Density etc)were studied. The study was focused on the influence of paitcle size.Surface modification,filling amount on the mechanic properties of the composites.The stractures of the system were investigated by using SEM,DSC and polarization micrascope.The results show that bentonite when modified by stewic acid,give good impact strength to the PP/bent composite.This may probabby be attributed to the bentonites acting as the nuclearation gent of PP,and resuting in the decreasing of crystal grain size of of PP.
