Abstract

The invention relates to the field of production of lubricating oil, in particular to polyether polyol and a synthetic method thereof and lubricating oil. The synthetic method of the polyether polyol comprises the following steps: by taking long-chain fatty alcohol as an initiator, carrying out polymerization reaction on the long-chain fatty alcohol and mixed epoxyalkane under the catalytic action of a catalyst to prepare the polyether polyol, wherein the mixed epoxyalkane comprises epoxypropane, ethylene oxide and epoxybutane according to a mass ratio of 75-95: 4-15: 1-10. The gear oil formed by adopting the specific polyether polyol as the raw material has the advantages of low viscosity, high viscosity index, high lightning and low pour point, and also has good fluidity under a low temperature condition, so that the abrasion caused in the starting process of the vehicle is greatly reduced.

Description

technical field

[0001] The invention relates to the field of lubricating oil production, in particular to a polyether polyol, a synthesis method thereof, and a lubricating oil. Background technique

[0002] Lubricating oil is widely used in life and production, and can be divided into internal combustion engine oil, gear oil, hydraulic oil, brake fluid and grease according to the application route. Lubricating oil not only has the basic function of lubrication, but also has the functions of controlling friction, reducing wear, cooling, sealing isolation and cleaning. There are two main components of lubricating oil, which are lubricating oil base oil and lubricating oil additives. In industrial applications, it is often necessary to combine different lubricating oil base oils and lubricating oil additives to produce lubricating oils for different parts and different working conditions. Oil.

[0003] Polyether polyol is an oil-soluble polymer synthesized by multiple monomer...
