CNTs对HDPE基复合材料在水润滑工况下摩擦行为影响的研究
|
摘要
采用熔融挤出注射成型法制备不同碳纳米管(CNTs)用量的碳纳米管/马来酸酐接枝聚丙烯(PPG)/高密度聚乙烯(HDPE)(CNTs/PPG/HDPE)复合材料;研究了复合材料在水润滑工况,50N和150N载荷条件下的摩擦性能;并观察了CNTs的分布及磨损表面形貌和表面粗糙度。结果表明:CNTs的加入可以有效减轻磨损,在50N和150N的不同载荷条件下,添加1.2%(wt,质量分数)CNTs的CNTs/PPG/HDPE在水润滑摩擦工况条件下都具有低较的磨损率,并能防止剥落的发生。在150N载荷,水润滑条件下,CNTs用量为1.2%(wt,质量分数)制得的CNTs/PPG/HDPE的摩擦系数最小值为0.161,磨损率为0.932×10~(-5) mm~3/N·m,粗糙度为2531nm,具有较好的摩擦性能。
The carbon nanotubes/maleic anhydride grafted polypropylene(PPG)/high density polyethylene(HDPE)composites with different amounts of carbon nanotubes(CNTs)were prepared by melt extrusion injection molding.The friction performance of composites under water lubrication conditions was studied under 50 Nand 150 N loading.The distribution of CNTs,the surface morphology and roughness of wear were observed.The results showed that the addition of CNTs can effectively reduce the wear.Under different load conditions of 50 Nand 150 N,CNTs/PPG/HDPE with 1.2%(wt,mass fraction)CNTs had low wear rate under water-lubricated friction conditions,and prevented spalling.Under 150 Nload and water lubrication conditions,the minimum friction coefficient of CNTs/PPG/HDPE prepared by using CNTs at 1.2 wt% was 0.161,and the wear rate was 0.932×10~(-5) mm~3/N·m,the roughness was 2531 nm.It had good friction properties.
