液体橡胶-环氧树脂复合材料在液体石蜡润滑下的摩擦性能

胡少坤  于晶  胡开放  陈继明  易建军  孟凡宁 

摘 要:用端异氰酸酯基液体橡胶与环氧树脂制得液体橡胶-环氧树脂聚合物(ETPB).在ETPB中分别加入质量分数为5%和10%的纳米Al2O3,并选择适宜的固化剂固化,制得ETPB-Al2O3复合材料.测试了ETPB,ETPB-Al2O3复合材料在液体石蜡润滑下的滑动摩擦性能,考察了磨损率及摩擦系数与载荷和滑动速度之间的关系,并用扫描电子显微镜(SEM)对几种材料磨损表面进行了观察.结果表明,端异氰酸酯基液体橡胶改性环氧树脂可显著提高抗磨损性能;填充纳米Al2O3无机粒子可显著提高ETPB的抗磨损性能,其最佳填充量为5%.
