Problems solved by technology

[0002] In the prior art, finished lubricating oils are almost all composed of base oils and additives, wherein the base oils are non-polar molecules, and the additives are compounds composed of polar molecules and non-polar molecules. Engine lubricating oils contain A large amount of engine lubricating oil compound additives, so the mixture of the two is an unstable system. When the oil is stored statically, the problem of additive sedimentation will occur as the storage time prolongs, so it is of great significance to solve this problem

Abstract

The invention discloses cis-12 hydroxy octadecenoic acid-3-methyl-imidazole hexafluorophosphate ionic liquid and a four-stroke engine lubricating oil composition containing the same, and belongs to the field of lubricating oil production. The lubricating oil composition is mainly mixed by the following raw materials according to the weight ratio: lubricating oil base oil, cis-12 hydroxy octadecenoic acid-3-methyl-imidazole hexafluorophosphate, a viscosity index improver, a dispersing agent, a clearing agent, an oxidation and corrosion inhibitor, a base number reserving agent and an antifoaming agent. Compared with the prior art, the cis-12 hydroxy octadecenoic acid-3-methyl-imidazole hexafluorophosphate ionic liquid solves the problem that various annexing agents are easy to separate out when lubricating oil is placed for a long time, has the characteristics of good usability, environmental protection, energy saving and the like, and has a good application and dissemination valve, and abrasion of an engine can be obviously reduced.

Description

technical field [0001] The invention relates to the field of lubricating oil production, in particular to a cis-12 hydroxyoctadecene-3-methyl-imidazole hexafluorophosphate ionic liquid and a four-stroke engine lubricating oil composition containing the ionic liquid. Background technique [0002] In the prior art, finished lubricating oils are almost all composed of base oils and additives, wherein the base oils are non-polar molecules, and the additives are compounds composed of polar molecules and non-polar molecules. Engine lubricating oils contain A large amount of engine lubricating oil compound additives, so the mixture of the two is an unstable system. When the oil is stored statically, the problem of additive sedimentation will occur as the storage time prolongs. Therefore, it is of great significance to solve this problem. [0003] Ionic liquid refers to a molten salt system mainly composed of organic cations and inorganic or organic anions, and is liquid below 100 °...
