Problems solved by technology

However, this kind of air compressor oil is easily oxidized to produce aldehydes, ketones, esters and other products during use. These oxidation products will form sludge after being mixed with water, impurities and other substances. The existence of sludge will block the oil circuit of the air compressor. And form carbon deposits on various parts of the air compressor, resulting in short oil life and causing air compressor failure

Abstract

The invention provides air compressor oil which comprises the following components in parts by weight: 75-94 parts of synthetic hydrocarbon base oil, 5-20 parts of synthetic ester base oil and 1-5 parts of functional additive, wherein the functional additive comprises a purification dispersant, an antiwear agent, a metal deactivator, an antirust agent, an antioxidant, a pour point depressant, a demulsifying agent and an anti-foaming agent. The invention provides a preparation method of the air compressor oil. The preparation method comprises the step of mixing the synthetic hydrocarbon base oil, the synthetic ester base oil and the functional additive at the temperature of 60-80DEG C to obtain the air compressor oil. According to the air compressor oil provided by the invention, the synthetic oil is used as the base oil and the compound type functional additive is added, so that the air compressor oil provided by the invention has low oil sludge property. In addition, the air compressor oil provided by the invention also has the advantages of better thermal oxidation stability, low-temperature fluidity and higher viscosity index, and the use requirement of an air compressor is met.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an air compressor oil and a preparation method thereof. Background technique [0002] An air compressor is a general-purpose machine powered by compressed air. The most commonly used air compressors are screw air compressors, piston air compressors and centrifugal air compressors. Air compressors are widely used in mining, chemical industry, machinery, food and other fields. Air compressor oil is mainly used for the lubrication of air compressors, and some air compressor oils can also play the role of cooling, sealing, rust prevention and corrosion protection. With the development of air compressors, higher requirements are placed on air compressor oils, such as air compressor oils that require a longer oil change period. [0003] The Chinese patent application number 201210561736.7 discloses an air compressor oil, including: 20-30 parts of phosphite, 16-20 parts of fat...
