Description

technical field [0001] The invention relates to the technical field of ionic liquid lubricants, in particular to a hippurate anti-corrosion ionic liquid and a preparation method and application thereof. The hippurate anti-corrosion ionic liquid is used as an ionic liquid lubricant and has good corrosion resistance and good tribological properties. Background technique [0002] Ionic liquid is a molten salt system that is liquid at or near room temperature and is composed entirely of anions and cations. It generally has special properties necessary for a series of high-performance liquid lubricating materials such as low volatility, wide liquid range, high thermal stability and structural designability. It has great potential as a new high-performance liquid lubricant in aviation, aerospace and electronic information, etc. High-tech fields have been widely used (Zhou F, Liang Y.M., Liu W.M. Chem Soc Rev 2009; 38:2590-2599; Zhang S.W., Hu L.T., Qiao D., Tribol.Int., 2013; 66:...
