合成酯类润滑油水解性能研究现状

Research Status of Hydrolysis Performance of Synthetic Ester Lubricating Oil

合成酯类润滑油作为高性能润滑材料广泛应用于现代工业,然而由于分子结构中含有极性较强的酯键,遇水极易发生水解而失效,严重制约其应用和发展。综述了合成酯类基础油的水解失效机理、水解试验方法、水解稳定性影响因素以及水解抑制方法和手段,并展望了合成酯润滑油的水解性能研究方向。

As one of the most important high performance lubricants, synthetic ester has been widely applied in modern industry. However, due to the presence of ester bond in its molecule synthetic ester is more susceptible to hydrolysis, which seriously restricts its application. The hydrolysis mechanisms, test methods, influencing factors and inhibition methods of synthetic ester base oil were summarized, and some perspectives for future study on hydrolysis properties of synthetic ester were also given. © 2016, Science Press.
