功能化苯并三氮唑离子液体作为润滑油添加剂的摩擦学性能研究

Tribological Properties of Functionalized Benzotriazolium Ionic Liquid as Lubricant Additive

  • 摘要: 本文作者通过两步法合成一种含酯基的功能化离子液体1-乙酸乙酯基苯并三氮唑四氟硼酸盐, 采用傅里叶红外光谱仪对其进行结构表征. 采用四球摩擦磨损试验机测其在葵花籽油中的摩擦学性能, 并与基础油进行对比. 采用光学显微镜, 扫描电子显微镜(SEM)和X射线光电子能谱仪(XPS)分别对钢球磨斑表面形貌和主要元素进行观察和分析. 结果表明: 该离子液体在葵花籽油中表现出良好的减摩抗磨效果; 与基础油相比, 当离子液体质量分数为1.5%时, 摩擦系数和磨斑直径均达到最小值, 分别减少了42.9%和33.3%. XPS结果表明摩擦过程中在接触面形成一层摩擦保护膜.

     

    Abstract: In this work, a new kind of functionalized ionic liquid (IL) containing ester-group, 1-ethoxycarbonylmethyl benzotrizaole terafluoroborate, was synthesized through a typical two-step way and characterized by Fourier Transform infrared spectroscopy. Tribological experiments were performed on a four-ball friction and wear tester with as-prepared IL lubricant mixtures, and compared with neat sunflower oil. The morphologies and main elements of the worn surfaces were observed and evaluated by optical microscopy, scanning electron microscope(SEM)and X-ray photoelectron spectroscopy(XPS). The results show that the prepared IL possessed excellent friction-reducing and anti-wear properties. When the addition concentration was 1.5%, the friction coefficient and the wear scar diameter were both smallest, and decreased by 42.9% and 33.3%, respectively, as compared to the base oil without ionic liquid. XPS results demonstrate that a protective triblo-film was formed on the contact surface during friction progress.
