Problems solved by technology

Although improving the demulsification performance can temporarily solve the impact of water ingress on gear oil, the additives in gear oil are often gradually reduced with the separation of water
The existence of a small amount of water is still easy to cause lubrication failure
Direct replacement of gear oil increases the cost of use of the enterprise

Abstract

The invention discloses a transmission gear lubricating oil, which is prepared from the following raw materials by weight: 6-10 parts of dodec-olefin succinic acid, 2-7 parts of calcium dialkylbenzene sulfonate, 3-7 parts of fatty alcohol polyoxyethylene ether carboxylic acid, 10-20 parts of oleic acid, 4-8 parts of diethylene triamine pentamethylene phosphonic acid, 15-25 parts of polyalkylene glycol, 6-10 parts of cocinic acid glycol amide, 2-5 parts of methylsilicone oil, 7-9 parts of a macromolecular polyisobutene oil solution, 6-8 parts of inositol hexaphosphate, 7-11 parts of imidazoline, 2-6 parts of triphenyl thiophosphate, and 3-8 parts of phosphate ester and its ammonium salt derivative. The transmission gear lubricating oil provided by the invention has excellent viscosity-temperature performance, low condensation point and high water capacity, can improve lubricating performance, and has excellent antirust effect.

Description

technical field [0001] The invention relates to the technical field of chemicals, in particular to a transmission gear lubricating oil. Background technique [0002] Gear oil is an important lubricating oil prepared mainly from mineral base oil or synthetic base oil with extreme pressure anti-wear agent and oily agent. Gear oil should have good anti-wear, load resistance and suitable viscosity . In addition, it should also have good thermo-oxidative stability, anti-foaming properties, water separation performance and anti-rust performance. Even under high operating temperature and load, the synthetic gear oil can still ensure that the various parts of the transmission system are not worn. In industrial production, cooling water often leaks into the lubrication system due to poor sealing, resulting in emulsification and deterioration of the lubricating oil, blocking the oil circuit, and forcing the replacement of lubricating oil to ensure the normal operation of production. ...
