Abstract

A 2,5-bis-dodecyldisulfanyl-3-ethyl-1,3,4-thiadiazole (BDET) based ionic liquid (IL) was synthesized and its tribological performance as an additive in ester-based oil (DIPE) was evaluated. The tribological performance of [BDET][BF4] was compared with that of a commercial additive, zinc dialkyl dithiophosphates (ZDDP). It was found that [BDET][BF4] resulted in a 12 % reduction in the friction coefficient in comparison to base oil. Furthermore, it displays excellent wear protection characteristics, exhibiting the lowest wear volume, which is half that of ZDDP and only one-fifteenth of the base oil. Noteworthily, [BDET][BF4] is capable of forming a tribofilm with a thickness of 2 μm, which is more than 10 times greater than that of ZDDP. Surface analysis indicates that the outstanding tribological performance of [BDET][BF4] is attributable to the coexistence of an adsorption layer and a tribo-chemical reaction film. Moreover, the presence of a thiadiazole group in its molecular structure enables [BDET][BF4] to exhibit effective corrosion inhibition towards copper. In general, the simple preparation procedure, favorable tribological characteristics and anticorrosion properties make [BDET][BF4] an effective multifunctional additive in lubricants.
作为多功能润滑油添加剂的新型噻二唑衍生物的合成与摩擦学研究
合成了一种基于 2,5-双十二烷基二硫-3-乙基-1,3,4-噻二唑(BDET)的离子液体(IL),并对其作为酯基油(DIPE)添加剂的摩擦学性能进行了评估。将[BDET][BF4]的摩擦学性能与商用添加剂二烷基二硫代磷酸锌(ZDDP)的摩擦学性能进行了比较。结果发现,与基础油相比,[BDET][BF4] 的摩擦系数降低了 12%。此外,[BDET][BF4]还具有出色的磨损保护特性,磨损量最低,仅为 ZDDP 的一半,基础油的十五分之一。值得注意的是,[BDET][BF4] 能够形成厚度为 2 μm 的三膜,是 ZDDP 厚度的 10 倍以上。表面分析表明,[BDET][BF4] 杰出的摩擦学性能得益于吸附层和三化学反应膜的共存。此外,由于[BDET][BF4]分子结构中含有噻二唑基团,因此能有效抑制铜的腐蚀。总之,[BDET][BF4]制备过程简单,具有良好的摩擦学特性和防腐性能,是润滑油中一种有效的多功能添加剂。
