Abstract

The invention relates to an air compressor oil complexing agent, a preparation method for the same and an air compressor oil composition. The air compressor oil complexing agent comprises A, at least one sulfur-containing compound, B, at least one phenol antioxidant, C, at least one metal deactivator, D, at least one demulsifier, E, at least one antifoaming agent and F, at least one kind of base oil. The complexing agent does not contain any amine antioxidant and metal ions, is non-discoloring in use, free of catalysis over the oxidation of an oil product, high in service performance, easy to prepare, low in cost and favorable for industrial popularization and application, has high oxidation stability, and is particularly applied to working places with high requirements on the color of air compressor oil. The invention also relates to the preparation method for the air compressor oil complexing agent and the air compressor oil composition.

Description

technical field [0001] The invention relates to an air compressor oil compounding agent, in particular to an ashless air compressor oil compounding agent with strong oxidation resistance and stable appearance and color, especially suitable for industries with high requirements on the color of air compressor oil. Situation. The invention also relates to a preparation method of the air compressor oil compounding agent and an air compressor oil composition containing the air compressor oil compounding agent. Background technique [0002] 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 ox...
