Description

Technical field:

[0001] The invention relates to the technical field of lubricating oil for air compressors, in particular it is a lubricating oil for an oil-sprayed rotary type, that is, a sliding vane and screw type air compressor, and a preparation method thereof Background technique:

[0002] The air compressor oil used in the past is maintained entirely by the anti-oxidation stability, anti-rust and lubricity of mineral oil itself.

[0003] In recent years, due to the development of compressor manufacturing technology, a compound formula of shielding phenolic antioxidant and zinc dialkyl dithiophosphate type high-temperature anti-oxidation, anti-corrosion, and anti-wear agent has been introduced into the new generation of compressor oil, thereby improving Improve the quality of air compressor oil. However, since the zinc dialkyldithiophosphate additive in this formula will decompose under long-term oxygen enrichment and high temperature conditions, and once the decompo...
