国产mPAO150基础油在黏度指数改进剂方面的应用研究

Applied Research on Domestic mPAO150 Base Oil as A Viscosity Index Improver

为推进黏度指数改进剂的国产化替代,进一步拓展mPAO基础油的应用领域,文章考察了国产mPAO150基础油作为黏度指数改进剂在0W-20汽油机油、75W-90 GL-5重负荷车辆齿轮油、L-HS 46低温液压油等高端润滑油的应用可行性。试验结果表明:采用国产mPAO150基础油调制的0W-20汽油机油、75W-90 GL-5重负荷车辆齿轮油、L-HS 46低温液压油理化性能均满足指标要求,与OCP、PMA、HSD等常用的进口黏度指数改进剂相比,剪切安定性、抗结焦性能具有突出优势,可替代进口黏度指数改进剂。

To promote the replacement with viscosity index improvers made in China and further expand the application of mPAO base oil,the application feasibility of domestic mPAO150 base oil as viscosity index improver in high-end lubricating oils such as 0W-20 gasoline engine oil,75W-90 GL-5 heavy-duty vehicle gear oil and L-HS 46 low-temperature hydraulic oil was investigated.The results show that the physical and chemical properties of 0W-20 gasoline engine oil,75W-90 GL-5 heavy-duty vehicle gear oil and L-HS 46 low-temperature hydraulic oil formulated with domestic mPAO150 base oil meet the required performance indicators.Compared with commonly used imported viscosity index improvers such as OCP,PMA,and HSD,mPAO has outstanding advantages in shear stability and anti-coking property and can replace imported viscosity index improver.
