摘　　要：对添加不同牌号(R61,R51和R11)和不同用量纳米凹凸棒土(AT)的丁腈橡胶(NBR)性能进行研究。结果表明:随着AT用量增大,NBR胶料的物理性能提高,耐磨性能降低;采用AT R61的NBR胶料耐磨性能较好,采用AT R11的NBR胶料综合物理性能较好;与添加相同用量白炭黑的NBR胶料相比,添加AT的NBR胶料性能总体较差;AT R51/白炭黑并用比为10/30的NBR胶料物理性能与白炭黑用量为40份的NBR胶料的物理性能接近,AT与白炭黑并用可以提高胶料性价比。In this study, the properties of NBR with different grade of nano-attapulgite （AT） , R61, R51 and R11, and different AT loading amount were investigated. The results showed that, with the increase of AT amount, the physical properties of NBR were improved, but the wear resistance decreased. The wear resistance of NBR with AT R61 was better,while the overall physical properties of NBR with AT Rll were better. Compared with the NBR with the same amount of silica, the physical properties of NBR with AT filler were lower. It was found that combination of AT and silica could improve the performance cost ratio of NBR compound, while the physical properties of NBR filled with 10 phr of AT R51 and 30 phr of silica were similar to that filled with 40 phr of silica.
