Problems solved by technology

Lubricating oil with too low viscosity is not easy to form a strong enough oil film, which will accelerate wear and shorten the service life of parts
On the contrary, if the viscosity of the lubricating oil is too high, it will increase the internal friction force, increase the specific power of the compressor, and increase the power consumption and oil consumption. Formation of sediment
Compressor oil is prone to emulsification during operation, resulting in unclear separation of oil and gas and increased oil consumption. At the same time, the oil is emulsified to damage the oil film, which will cause increased wear

Abstract

The invention discloses oil-soluble polyether oil for a screw-type air compressor. The oil-soluble polyether oil is prepared from 20-40 parts or 10-20 parts by mass of oil-soluble polyether base oil, 60-80 parts or 80-90 parts by mass of poly(alpha-olefin), 0.1-1.4 parts by mass of benzenamine, 0.8-2 parts by mass of a borate anti-oxidant, 1.2-2.2 parts by mass of a high-temperature ashless antiwear agent, 0.5-1.8 parts by mass of polyoxyethylene sorbitan fatty acid ester and 0.001-0.05 parts by mass of an acrylate-ether copolymer. The oil-soluble polyether oil for a screw-type air compressor is environmentally friendly, has the advantages of excellent antioxidation stability, emulsification resistance, corrosion and rusting resistance, very good defoaming performance and excellent viscosity-temperature performance, has performance indexes satisfying standards of air compressor oil 46 and can be used for mechanical equipment of an air compressor system.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to a screw air compressor oil which is compatible with mineral oil and synthetic hydrocarbon and has biodegradability. Background technique [0002] Air compressor oil is mainly used for the lubrication of the moving parts of the compressor cylinder and the exhaust valve, and plays the role of anti-rust, anti-corrosion, sealing and cooling. Since the compressor is always in an environment of high pressure, high temperature and condensed water (for air compressors), the air compressor oil should have excellent high temperature oxidation stability, low carbon deposition tendency, suitable viscosity and viscosity temperature Performance and good oil-water separation, anti-rust and anti-corrosion properties, etc. Lubricating oil with too low viscosity is not easy to form a strong enough oil film, which will accelerate wear and shorten the service life of parts. On the contrary...
