| 摘 要： | 以环氧树脂(EP)为改性剂,研究了三种不同摩尔质量软质聚氯乙烯(S-PVC)的力学性能,考察了EP含量,后热处理等条件对S-PVC/EP复合材料性能的影响。实验结果表明:EP能有效降低S-PVC的压缩永久变形;后热处理使得EP进一步固化,有利于压缩永久变形的降低;随着PVC摩尔质量的增加,S-PVC/EP复合材料的力学性能提高。

| Abstract: | Epoxy resin(EP)was added to modify three kinds of soft PVC with different molecular weight.The effect of EP content,post-heat treatment on properties of S-PVC/EP composites was studied.The results showed that:EP can decrease the compression set of S-PVC effectively;the post-heat treatment increased the curing density of EP obviously and helped to decrease the compression set;with increasing of molecular weight of PVC,the mechanical properties of S-PVC/EP composites increased. |
