摘　　要：以中海油气(泰州)石化有限公司生产的石蜡基润滑油基础油为原料,添加一定量的复合添加剂、黏度指数改进剂、有机钼摩擦改进剂、高分子聚合物摩擦改进剂等,制备了符合GB/T 11122—2006质量标准的4种重负荷柴油机油CI-4 15W-40,主要考察摩擦改进剂对重负荷柴油机油的理化性能、抗磨极压性能、行车性能的影响。结果表明,有机钼摩擦改进剂在低温下需要磨合一定时间后起作用,高分子聚合物摩擦改进剂对于油品的极压性能提升明显,两种摩擦改进剂之间存在协同作用,在行车试验中可使车辆燃油经济性提升1%~2%。With the development of logistics industry and infrastructure industry,the requirements for heavy truck fuel economy are constantly improving.Four heavy duty diesel engine oils CI-4 15W-40,which meet the quality standards of GB/T 11122—2006,were prepared by using paraffin-based lubricating base oil produced by CNOOC(Taizhou)Petrochemical Co.Ltd.as raw materials,adding a certain amount of compound additives,viscosity index improvers,organic molybdenum friction improvers,polymer friction improvers.The effects of friction modifiers on physical and chemical properties,anti-wear and extreme pressure properties and driving performance of heavy duty diesel engine oil were mainly investigated.The results showed that it took time for the organic molybdenum friction modifier to display the effect at low temperature,and the polymer friction modifier could significantly improve the extreme pressure performance.There was a synergistic effect between the two friction modifiers,which could improve the fuel economy of vehicles by 1%-2%in driving test.
