摘　　要：文章以丁腈橡胶(NBR)为基体,采用溶液共混法制备了丁腈橡胶、丁腈橡胶/碳纳米管(NBR/MWNT)、丁腈橡胶/羧基碳纳米管(NBR/MWNT-COOH)、丁腈橡胶/羟基碳纳米管(NBR/MWNT-OH) 4种复合材料。利用多功能摩擦试验机(RTEC)开展了橡胶试块与铸造铜合金(ZCuSn10Zn2)环块之间的速度特性实验和磨损特性实验。试验结果表明:碳纳米管(MWNT)具有改善橡胶润滑性能的作用,同时磨损试验表明MWNT能够提高橡胶的耐磨性,填充了MWNT-COOH的复合材料具有最佳的摩擦磨损性能。Nitrile butadiene rubber( NBR),nitrile butadiene rubber/multi-walled carbon nanotube( NBR/MWNT),nitrile butadiene rubber/carboxy multi-walled carbon nanotube( NBR/MWNT-COOH),nitrile butadiene rubber/hydroxy multi-walled carbon nanotubes( NBR/MWNT-OH) four composite materials were prepared by solution blending with nitrile butadienerubber( NBR) as the matrix. Velocity characteristics experiments and wear characteristics experiments between rubber test blocks and cast copper alloy( ZCuSn10Zn2) ring blocks were carried out using a multi-functional friction tester( RTEC). The test results show that multi-walled carbon nanotubes( MWNT) have the effect of improving rubber lubrication performance. At the same time,the wear test shows that MWNT can improve the wear resistance of rubber. The composite material filled with MWNT-COOH has the best friction and wear properties.
