Long-life air compressor oil composition

Abstract

The invention discloses a long-life air compressor oil composition. The long-life air compressor oil composition comprises the following components in percentage by weight: 0.6-1.5% of an ashless composite additive, 0.3%-1.0% of an antioxidant, 0.1%-0.5% of an extreme pressure anti-wear agent, and 0.002% to 0.005% of an anti-foaming agent, with the balance being base oil, wherein the base oil comprises a mixture of III-type hydrogenated base oil and alkyl naphthalene base oil or polyether base oil. The air compressor oil provided by the invention has excellent high-temperature detergency and oxidation resistance, and can effectively avoid the generation of oil sludge and carbon deposit; excellent wear resistance and hydrolytic stability are achieved, and excellent wear resistance protection is provided for the air compressor; the excellent heat conduction efficiency can help to reduce the temperature and oil temperature of the compressor; and the oil change period is long and can reach6000 hours or above. In addition, compared with known long-life air compressor oil, the air compressor oil has the advantages of being low in cost, simple in preparation method, easy to popularize and apply on a large scale and the like.

Description

technical field

[0001] The invention relates to a lubricating oil composition, in particular to a long-life air compressor oil composition. Background technique

[0002] The main lubricating parts of air compressor oil, especially the screw air compressor oil that currently dominates the market, are screws, bearings, gears, etc., and the oil circulates to cool, carry heat, clean, and seal the screw and shell. Compared with other types of lubricating oil, the working environment of air compressor oil is extremely harsh, mainly as follows: (1) high temperature, when the air compressor is working, the lubricating oil has to absorb the compression heat generated when the gas is compressed, and the entire operation process The medium compressor oil is a circulating heat carrier, and its working temperature has been kept above 90°C. (2) High-pressure oxidation, because the oxygen partial pressure increases with the pressure of the compressed air, and the oxidation of the compress...
