粘土/天然橡胶复合材料的制备与性能研究

采用分散剂多聚脂肪酸盐水杨酰亚胺制备粘土/天然橡胶（NR）复合材料，并对其性能进行研究。结果表明：当水杨酰亚胺用量为0.015份、粘土用量为50份、不添加偶联剂或环氧化天然橡胶时，所制得的粘土/NR复合材料具有优异的拉伸性能、抗撕裂性能、耐磨性能以及较低的压缩生热；粘土在NR基体中均匀分散。;The clay/NR composite was prepared by using dispersing agent，salt of polyunsaturated fatty acid and benzoyl acid imide， and its properties were investigated.The results showed that，when the addition levels of clay and dispersing agent were 50 phr and 0.015 phr，respectively，the clay was uniformly dispersed without the use of coupling agent or epoxidized natural rubber，and the clay/NR composite had excellent tensile property，tear resistance and abrasion resistance，and low heat build-up
