Problems solved by technology

Among commonly used synthetic oils, polyether has the best heat transfer efficiency, but at present, polyalphaolefin and ester oils are mostly used in synthetic compressor oil base oils, such as a composite synthetic air compressor oil disclosed in Chinese patent application CN101538501A, It is made of diisoalkyl branched dibasic acid ester, diisoalkyl phthalate and polyalphaolefin as base oil, adding antioxidant and other additives. It is not as good as polyether type air compressor oil

Abstract

The invention provides an air compressor oil composition and a preparation method thereof. The air compressor oil composition comprises polyether oil base oil or polyether oil and ester oil mixture base oil, a 2,2,4-trialkyl-1,2-dihydroquinoline antioxidant and a metal deactivator. Compared with the known air compressor oil composition, the air compressor oil composition has excellent oxidation stability, excellent comprehensive performance and a simple preparation method, and is particularly suitable for a screw air compressor.

Description

technical field [0001] The present invention relates to an air compressor oil composition, specifically a clean lubricating oil composition with high oxidation stability, detergency and forced cooling effect, especially suitable for screw air compressors. The composition can also be used as a screw air compressor coolant. Background technique [0002] Air compressor oil, especially the screw air compressor oil that currently dominates the market, mainly lubricates the screw, bearings, gears, etc., through the oil circulation, it plays the role of cooling, carrying heat, cleaning, and sealing the screw and the shell. [0003] Compared with other types of lubricating oils, the working environment of air compressor oil is extremely harsh, mainly manifested in high temperature, high oxygen partial pressure, moisture and metal catalysis, and long-term work. Higher thermo-oxidative stability. The high temperature oxidation resistance of oil can be improved by using phenolic amin...
