Abstract

The present invention relates to the application of an ionic liquid as a lubricating oil additive. The amount added to the lubricating oil composition is 0.05wt% to 10wt% of the lubricating oil. The general formula (I) of the ionic liquid is as follows: In the formula, R 1 ~R 4 C is a straight or branched chain 1 ~C 20 Alkyl, cycloalkyl, aryl, aralkyl, R 1 ~R 4 Can be the same or different. The ionic liquid is mainly used in vehicle manual transmission oil, automatic transmission fluid and dual-clutch transmission oil. It has excellent friction durability, good thermal stability and anti-corrosion performance.

Description

technical field [0001] The invention relates to an ionic liquid lubricating oil additive, in particular to the application of an imidazole ionic liquid as a lubricating oil additive. Background technique [0002] Ionic liquids have the characteristics of non-flammable and explosive, low melting point, extremely low volatility and high thermal stability, which are very consistent with the expected properties of ideal lubricants. They are a new type of lubricant with great development prospects. At the same time, due to the unique designability of ionic liquids, one or more functional groups can be introduced into the cations or anions of ionic liquids, that is, the functionalization of ionic liquids. Therefore, introducing specific functional groups into traditional ionic liquids can make them excellent lubricating oil additives. [0003] With the continuous development of gearbox structure, the requirements for gearbox oil are getting higher and higher. Especially for spec...
