为开发可作为硫化烯烃替代物的润滑油添加剂,合成了一种含黄原酸基团的硼酸酯衍生物(BXT)并对其结构进行了表征.利用四球摩擦磨损试验机对该化合物在菜籽油中的摩擦学性能进行了评价.结果表明,BXT在菜籽油中具有优异的承载能力、减摩及抗磨性能;与硫化烯烃相比,BXT没有明显的气味,铜腐蚀程度低且热稳定性高.采用三维表面轮廓仪及X射线光电子能谱(XPS)对钢球磨损表面的形貌和元素状态进行了分析,初步研究了BXT在摩擦过程中的作用机理. To develop a lubricating oil additive that can be used as a substitute for sulfurized olefin, a boronic acid ester derivative (BXT) containing a xanthogen acid group was synthesized and its structure was characterized by using a four-ball friction and wear tester The tribological properties of rapeseed oil were evaluated.The results show that BXT has excellent load-bearing capacity, anti-friction and anti-wear properties in rapeseed oil.Compared with sulfurized olefin, BXT has no obvious odor and low copper corrosion And its thermal stability is high.Using the three-dimensional surface profiler and X-ray photoelectron spectroscopy (XPS) to analyze the morphology and elemental state of the ball wear surface, the mechanism of BXT in the friction process is preliminary studied.
