摘　　要：噻二唑单体或单体衍生物是润滑油脂的抗磨剂,但不具备极压性能。噻二唑二聚体衍生物具有优秀的四球抗烧结性能,但梯姆肯OK值较低。噻二唑多聚体衍生物既具有优秀的四球极压性能,也具有优秀的梯姆肯极压性能。噻二唑衍生物用做润滑油脂抗磨极压剂,还具有抗氧、抑制铜腐蚀等多方面功能,克服了传统极压添加剂导致油品抗氧化性能降低、铜腐蚀严重的弊端。噻二唑衍生物无灰,不含磷和重金属元素,是环境友好的润滑油脂添加剂。特别是噻二唑二聚物与丁氧基三乙二醇复合物还具有良好的生物降解特性。The thiadiazole monomer derivatives are effective antiwear additives in lubricants, but do not demonstrate any extreme pressure (EP) properties. The thiadiazole dimer derivatives show excellent four ball weld properties, but with relatively low Timken values. The thiadiazole polymer derivatives afford high Timken pass values and four-ball weld results simultaneously. The thiadiazole derivatives can also serve as antioxidants and copper corrosion inhibitors for lubricants, which overcome the shortages of lowering the antioxidation capacity and corroding the metal copper incurred by traditional EP additives. All the thiadiazole derivatives are low-ash, environmentally friendly lubricant additives without phosphorus and heavy metals, and especially, both thiadiazole dimer and butoxytriglycol complex are biodegradable materials.
