摘要
通过密炼、压制成型制备了辉绿岩短纤维增强聚氯乙烯复合材料 ,研究了辉绿岩纤维增强聚氯乙烯复合材料中辉绿岩纤维的表面处理及加入量对力学性能的影响 ,并用SEM对复合材料的界面及其对复合材料力学性能的影响进行了表征。结果表明 :细质辉绿岩的增强效果较好 ,填充 2 0wt%的细质辉绿岩使拉伸强度提高了 35 % ,填充 10wt%的细质辉绿岩使冲击强度提高了 75 %。
The reinforced effects of two kinds of diabase were compared. The dosage of the fiber and the types of coupling agents were studied which influence the mechanical properties. SEM was used to analyze and test the structure of the diabase/PVC composites. Conclusions are as follows: the reinforced effect of No. 1 diabase is preferable. With the addition of diabase, the strength of the composite first increases and then decreases. The results show that the mixed coupling agent is the best choice.
