Abstract
The invention provides an industrial lubricating oil composition, which comprises a phenolic derivative, an extreme pressure anti-wear agent, a metal deactivator, an antirust agent, an anti-emulsifier and a main amount of lubricating base oil, wherein the phenolic derivative has a structure shown in a general formula (I):
Description
Technical Field
The invention relates to the field of lubricating oil, in particular to an industrial lubricating oil composition with long service life and a preparation method thereof.
Background
The industrial lubricating oil has wide application range, including turbine oil, industrial gear oil, oil film bearing oil, turbine worm oil, spindle oil, antirust oil, guide rail oil, chain oil, etc.
At present, widely used gas turbines, steam turbines and hydraulic turbines all require turbine lubricating oil to have higher bearing capacity and longer service life. The lubricating parts of the steam turbine are mainly a gearbox and a rotor bearing, and because the rotor shaft seal of the steam turbine has the possibility of steam leakage, the lubricating system has high possibility of water inflow, and the equipment has high rotating speed, large load and long running period, so the requirements on the oxidation resistance, the rust resistance and the emulsification resistance of oil products are high. The gas turbine directly applies work by using gas generated by combustion, and the gas turbine lubricating oil is acted by the hot surface of the bearing and used under the high pressure of a speed regulating system, and has excellent oxidation stability, thermal stability and good antirust and anti-emulsifying properties. The turbine lubricating oil used by the steam and gas combined cycle system is required to meet the lubricating requirements of both the steam turbine and the gas turbine.
Industrial gear oils are often subjected to severe conditions of high temperature and high load, and are required to exhibit good extreme pressure antiwear, oxidation resistance, and emulsification resistance.
With the technical progress of related mechanical equipment and the increasingly strict environmental requirements, other types of industrial lubricating oils are also in more severe working environments. Therefore, these industrial lubricating oils are required to have a longer service life, excellent load-bearing properties and wear resistance, excellent corrosion resistance and rust resistance, and good demulsification properties to various degrees.
The antioxidant is an essential additive in the lubricating oil, and mainly comprises hindered phenol type, amine type, phenolic ester type, thioester type, phosphite type and the like, wherein the hindered phenol type antioxidant is widely applied due to the excellent antioxidant effect of the hindered phenol type antioxidant, but the hindered phenol type antioxidant generally has a structure of 2,6-ditert-butyl-p-cresol (BHT), has certain toxicity, and does not accord with the development trend of green and environment-friendly additives.
The search for more effective antioxidant additives and the development of new high performance industrial lubricating oils continues to be a goal of efforts by those skilled in the art.
