Lubricant composition containing corrosion resistant ionic liquid

Abstract

The invention discloses a lubricant composition containing a corrosion resistant ionic liquid. The composition comprises, by mass, 99.9%-98% of base oil and 0.1%-2% of the corrosion resistant ionic liquid, wherein the base oil is selected from multiply-alkylated cyclopentane with 2 to 5 alkyl chains, the corrosion resistant ionic liquid is obtained by compounding one of benzotriazole diglycol mono methyl ether, benzotriazole triglycol mono methyl ether and benzotriazole tetraglycol mono methyl ether with one of lithium tetrafluoroborate, lithium hexafluorophosphate, lithium trifluoromethanesulfonate and lithium bis(trifluoromethanesulphonyl)imide. The ionic liquid and the lubricant composition can be synchronously synthesized, the process is simple, and the lubricant composition has good corrosion resistance and excellent tribological properties.

Description

technical field

[0001] The invention relates to a lubricant composition containing an anti-corrosion ionic liquid. The lubricant composition of the ionic liquid has anti-corrosion properties and excellent anti-friction and anti-wear properties. Background technique

[0002] Since the 1940s, ionic liquids have become the frontier and research hotspot of contemporary chemical science due to their own advantages. Zhao, H. Chem. Eng. Comm. 2006, 193 , 1660-1677.), its characteristics of non-flammability, low melting point, extremely low volatility and high thermal stability are very consistent with the expected performance of ideal lubricants, and it has become a new type of lubricant with great development prospects. agent, and was first discovered and published internationally by Liu Weimin et al. in 2001 (Ye, C.; Liu, W.; Chen, Y.; Yu, L. Chem. Commun. 2001, 21 , 2244-2245.), since then aroused many researchers at home and abroad to study the tribological properties of ion...
