| 中文摘要: |
| 采用乳液法制备累托石（REC）/天然橡胶（NR）纳米复合材料，研究白炭黑对REC/NR复合材料结构和性能的影响。结果表明：白炭黑粒子可以插入累托石片层形成网络结构。加入少量白炭黑后，REC/NR复合材料的物理性能变化不大。随着白炭黑用量的增大，复合材料的抗湿滑性能、抗切割性能和耐磨性能提高，压缩生热逐渐增大，当白炭黑用量为15份时，复合材料的耐磨性能最好；当白炭黑用量为20份时，复合材料的抗切割性能和抗湿滑性能较好。 |
| 英文摘要: |
| The rectorite （REC）/NR nanocomposite was prepared by emulsion method，and the influence of silica on the structure and properties of REC/NR nanocomposites was investigated.The results showed that，silica particles could be intercalated into the REC layers，in which the silica network structure formed.The physical properties of REC/NR composites changed little by adding small amount of silica.As the addition level of silica increased，the wet skid resistance，cutting resistance and wear resistance were improved，and heat build-up was increased.When the addition level of silica was 15 phr，the composite possessed the best wear resistance.When the addition level of silica was 20 phr，the composite possessed good wet skid resistance with excellent cutting resistance. |
