摘要
制备了一种新型的水基润滑添加剂乳液聚苯乙烯_碳纳米管 (PSt_CNTs)。透射电镜 (TEM)显示PSt_CNTs粒子微观上是带小球的纳米管状形态。利用四球机测试了PSt_CNTs乳液的润滑性能 ,结果表明由于CNTs对粒子的增强作用 ,PSt_CNTs乳液较PSt乳液的承载能力及耐磨损能力都提高。PSt_CNTs最佳加入量为 1 0 % ,利用扫描电镜 (SEM)分析了磨损钢球的表面形态 。
A new type of water-based lubrication additive-colloidal polystyrene-carbon nanotubes(PSt-CNTs) has been prepared.TEM shows that the PSt-CNTs colloid is tubes with tiny balls in nanometer scale.Four-ball test results indicate that both the load-carrying capacity and anti-wear of the colloidal PSt-CNTs are much superior to those colloidal PSt owing to the additive reinforced by CNTs.The optimum colloidal PSt-CNTs content is 1.0 wt%.The worn surfaces were analyzed using SEM.Finally its lubrication mechanism was deduced preliminarily.
