剑麻短纤维补强环氧化天然橡胶／PVC复合材料的性能研究

刘惠伦　 张北龙　

摘　要：研究了剑麻短纤维用量和环氧化天然橡胶(ENR)／PVC共混比对剑麻短纤维补强ENR／PVC复合材料性能的影响。结果表明，该复合材料具有较高的硬度和纵向拉伸强度、较低的扯断伸长率和扯断永久变形、良好的耐油和耐老化性能。剑麻短纤维的用量宜为30份，EMR/PVC的共混比宜为70／30。

Abstract：The influence of the loading level of sisal short fibre and the blending ratio of ENR-50/PVC on the properties of sisal short fibre-reirdorced ENR-50/PVC composites was investigated. The results showed that the sisal short fibre-reinforced ENR-50/PVC had higher hardness and tensile strength in longitudinal direction, lower elongation at break and tensile set at break, good oil resistance and aging property;and the suitable loading level of sisal short fibre was 30 phr, and the suitable blending ratio of ENR-50/PVC was 70/30.
Keywords：ENR; PVC; sisal short fibre; composite
