摘　　要：通过试验比较分析了几种不同填料对PVC/NBR热塑性弹性体拉伸性能、压缩永久变形性能的影响。结果表明:滑石粉类填料填充的PVC/NBR热塑性弹性体,其拉伸强度优于碳酸钙类填料填充的弹性体,断裂伸长率低于碳酸钙类填料填充的弹性体;采用填料填充的弹性体,其压缩永久变形率均大于未填充弹性体,且以5μm滑石粉为填料时,材料的压缩永久变形率提高最少。The effects of some kinds of different fillers on the tensile properties and compression sets of PVC/NBP, thcrrnoplastic elastomcr were compared through experiments. The results show that： （1） tensile property of talc fillcd PVC/NBR thermoplastic clastomer is superior to that of CaCO3 filled PVC/ NBR thermoplastic elastorner, but the elongation at break is inferior to that of CaCO3 filled system; （2） Thc compression set of filled clastomer is higher than that of unfillcd clastomer, while filling with 5μm talc gives the least increase in comprcssion set.
