一种杂环衍生物作为润滑脂添加剂的性能研究

摘要

In order to meet the requirements of high quality grease product for wind power system, a new heterocyclic derivative additive containing sulfur (named as RHY317) was synthesized in laboratory. The tribological and anticorrosion properties of RHY317 used in 2# lithium complex grease were evaluated and compared with three other additives containing sulfur. In addition, the application study of wind power grease containing RHY317 was carried out. Test results indicate that RHY317 exhibits excellent extreme pressure performance, good antiwear property and corrosion resistance in base grease; when it is used as main EP/AW additive for wind power grease, the quality of the product can fully satisfy the specifications.%结合高档风电润滑脂产品开发的需要,在实验室合成了一种新型含硫杂环衍生物添加剂RHY317,在2号复合锂基脂中对其极压抗磨性能和防腐蚀性能进行评价,并与RHY313,S-1,S-2含硫型极压抗磨剂进行性能对比.结果表明,所研制的RHY317添加剂在基础脂中具有优异的极压性能、良好的抗磨性能和防腐蚀性能,以其作为极压抗磨主剂调制的风电润滑脂能够满足性能指标要求.
