摘　　要： 采用合成酯类油邻苯二甲酸二辛酯作为基础油合成复合锂基润滑脂,并对其进行各项性能指标分析,探究其综合性能及应用。制备的润滑脂具有很高的滴点和胶体安定性及较好的低温性能。热重分析表明将邻苯二甲酸二辛酯制备成脂后,其热稳定性有所提高.低温DSC表明成脂后,其结晶温度与酯油相同,仍然保持较好的低温性能。扫描电镜结果表明润滑脂形成致密的皂纤维结构。 Lithium complex grease was synthesized using dioctyl phthalate as base oil, and analyzed its overall performance and applications. The grease had high dropping point, colloidal stability and excellent low temperature performance. Thermogravimetric analysis showed that the thermal stability of DCP was improved after forming grease. Low temperature DSC result showed that the crystallization temperature of grease was the same as base oil, indicating a good low temperature performance. SEM results showed that the grease had formed compact fiber structure.
