摘　　要：采用单因素试验法,通过考察润滑油基础油(简称基础油)种类、加料顺序、转化阶段反应温度与反应时间对制得润滑脂性能的影响,优化高碱值复合磺酸钙基润滑脂的制备工艺。结果表明:在以基础油A为润滑脂基础油、加料顺序为在转化阶段同时加入高碱值磺酸钙和脂肪酸D、转化反应温度为85℃、反应时间为2.5 h的条件下制得的高碱值复合磺酸钙基润滑脂的性能最好,其滴点超过343℃,高于GB/T 3498—2008标准中的滴点高限,工作锥入度(0.1 mm)为279,钢网分油率为2.17%,极压抗磨性能优秀,多项性能优于市售同类润滑脂。The effects of base oil type,feeding sequence,reaction temperature and reaction time in the conversion stage on the properties of the prepared grease were investigated by single factor experiment,to optimize the preparation process of calcium sulfonate complex grease with high base number.The results showed that when base oil A was used as the base oil of grease,high alkaline calcium sulfonate and fatty acid D were added in the conversion stage,under the conditions of a conversion temperature of 85℃and a reaction time of 2.5 h,the performance of the high alkaline complex calcium sulfonate grease was the best,and its dropping point exceeded 343℃,which was higher than the dropping point height limit of GB/T 3498—2008 standard.The working cone penetration(0.1 mm)was 279,and the oil separation rate of steel mesh was 2.17%.The extreme pressure and anti-wear performance is excellent,and many properties are better than those of similar greases on the market.
