Abstract

The invention relates to an air compressor oil composition, which comprises the following components in percentage by weight: 1.5 to 5 percent of antioxidant, 0.03 to 0.5 percent of ashless antirust agent, 0.01 to 0.5 percent of metal deactivator, 0.01 to 1 percent of ashless antiwear agent, 0.001 to 0.01 percent of anti-foaming agent and the balance of base oil, wherein the base oil is prepared by mixing poly alpha-olefin with ester oil in a weight ratio of 7-9:3-1 or mixing hydrogenated oil with the ester oil in the weight ratio of 7-9:3-1; and the antioxidant is the mixture of dialkylaniline, high-molecular thioether phenol and 4,4-methylenedi(2,6-di-tert-butyl phenol) in the weight ratio of 1:0.1-10:0.1-10. The air compressor oil composition has the advantages of excellent high-temperature anti-oxidation stability, anti-carbon deposition property, abrasive resistance, obvious energy-saving effect, good cost performance and low cost.

Description

technical field [0001] The invention relates to a lubricating oil composition, especially an oil composition capable of satisfying light, medium and heavy duty air compressors. Background technique [0002] For reciprocating compressors, since the discharge temperature of the compressed gas is higher than the suction temperature, the compressor oil is required to have good viscosity-temperature performance, oxidation stability and suitable viscosity. Usually, the compressor oil adopts highly refined base oil and anti-corrosion oil. Formulated with additives for oxygen anti-corrosion and anti-wear properties. [0003] In recent years, with the enlargement of these industrial equipment and the development towards high-load, high-temperature, high-pressure (heavy load) operation, higher requirements have been placed on the safety and reliability of the compressor, and the safe and reliable operation of the compressor must be ensured , lubrication is one of the important links....
