摘要
合成了1,2-[N,N-二正丁基二硫代氨基甲酸基]乙醇(NSO1)和2-[2-苯并噻唑基]硫代乙醇(NSO2)2种添加剂,并采用FT-IR、ESI-MS和元素分析手段表征了其结构。考察了NSO1和NSO2的热稳定性及其在菜籽油(RO)中的油溶性。采用四球摩擦磨损试验研究了2种添加剂在菜籽油中的减摩、抗磨以及极压性能。采用扫描电子显微镜(SEM)、能谱分析仪(EDS)观察和分析了钢球磨斑表面形貌及元素组成。结果表明,NSO2的热稳定性优于NSO1,其摩擦学性能也明显优于NSO1。NSO2优异的摩擦学特性主要得益于其分子中含有杂环结构,在边界润滑中,能够起到极压、抗磨的作用。
Two kinds of additives, 1, 2-(N, N-dibutyl dithiocarbamate) ethanol named as NSO1 and 2-(2-benzothiazolylthio) ethanol named as NSO2 were synthesized and characterized by FT-IR, elemental analysis and ESI-MS. The thermal stability of NSO1 and NSO2 were studied by thermal analysis, and their solubilities in rapeseed oil were tested. The friction reducing, anti-wear and load-carrying capacities of NSO1 and NSO2 were investigated by four-ball test. The surface morphology and the elemental composition of the tribofilms were investigated by using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), respectively. The results revealed that the thermal stability of NSO2 was better than that of NSO1 under the same experimental conditions and NSO2 exhibited more superior tribological performances than NSO1. The excellent tribological properties of NSO2 may be due to the heterocyclic structure in its molecule, which plays an important role in extreme pressure and anti-wear of boundary lubrication. © 2016, Science Press.
