环氧化天然橡胶改性淀粉/天然橡胶复合材料性能的研究

采用环氧化度适中的环氧化天然橡胶（ENR-25）改性淀粉/NR复合材料，并对其性能进行研究。结果表明：添加ENR-25可以显著提高改性淀粉/NR复合材料的物理性能和耐磨性能，降低淀粉/NR复合材料作为胎面胶时的滚动阻力，改善抗湿滑性能；当ENR-25用量为5份时，复合材料的综合性能较好。;Starch/NR composites were modified by epoxidized natural rubber with moderate epoxy content（ENR-25），and the properties of the composites were investigated.The results showed that，incorporation of ENR-25 could enhance the physical properties of the composites，reduce the rolling resistance，and improve the wet skid resistance.When the addition level of ENR-25 was 5 phr，the comprehensive properties of starch/NR composite were better
