为了获得高韧性硅灰石填充β-聚丙烯基(W/β-PP)复合材料,采用负载庚二酸钙的硅灰石(β-W)填充聚丙烯(PP)制备.研究了W/β-PP复合材料中β-W的β成核作用,并对比了硅灰石和β-W填充PP基复合材料的力学性能.结果表明:硅灰石填充聚丙烯(W/PP)复合材料主要形成α-晶,而β-W对PP结晶具有强的β-成核作用;W/PP复合材料的缺口冲击强度低于β-聚丙烯(β-PP),硅灰石与PP的β-晶之间存在协同增韧作用,导致W/β PP复合材料的缺口冲击强度高于β PP;随着βW含量的增加,W/β-PP复合材料的缺口冲击强度先增大后减小,在其质量分数为5％时达到最大值;同时硅灰石的增强作用可以提高β-PP的刚性.
