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,in- corporation of ENR-25 could enhance the physical properties of the composites,reduce the rolling re- sistance,and improve the wet-skid resistance. When the addition level of ENR-25 was 5 phr,the com- prehensive properties of starch/NR composite were better.
