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 an air compressor oil composition prepared from the following raw materials in parts by mass: 20-40 parts of oil soluble polyether based oil, 40-50 parts of poly(alpha-olefin), 10-15 parts of C10-C12 diisoalkyl phthalic acid ester, 0.1-1.4 parts of alkylated diphenylamine, 0.8-2 parts of a boric acid ester type antioxidant, 1.2-2.2 parts of alkyl thiophosphate, 0.5-1.8 parts of sorbitol fatty acid ester, 0.05-0.5 part of alkenyl succinate or alkenyl succinate semi-ester, 0.001-0.05 part of an acrylate and ether copolymer, 0.001-0.02 part of polyethylene alkyl ether, 0.002-0.01 part of organic silicate ester, and 0.1-0.4 part of benzotriazole. The obtained air compressor oil composition is environmentally friendly, has the advantages of excellent antioxidation stability, abrasive resistance, emulsifying resistance, corrosion and rust resistance, extremely good defoaming properties, excellent viscosity temperature properties and the like, has the performance indicators reaching No.46 air compressor oil standards, and is used for air compression system mechanical equipment and the like.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a preparation method of an air compressor oil composition. 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, if the viscosity of the lubricating oil is ...
