Problems solved by technology

Many additives are lipophilic or hydrophilic surfactants in chemical structure, and these compounds will cause the emulsification of lubricating oil in the case of water. In addition, the lubricating oil will be oxidized by air during storage. Oxygen compounds, causing emulsification of lubricating oil, making it difficult to separate oil and water

Abstract

The invention discloses a composite air compressor oil composition. The composite air compressor oil composition comprises mineral base oil, poly alpha olefin, phosphite ester, polyalkylene glycol, extreme-pressure antifriction micropowder and composite emulsion-resistant agents. The extreme-pressure antifriction micropowder is metal nanopowder subjected to emulsification and electro-deposition. Compared with the prior art, the composite air compressor oil composition has the advantages that that the mineral oil and composite oil are blended proportionally, so that high cost performance is achieved, the defect of pure mineral or composite compressor oil is overcome, compatibility among components is high, and the oil composition has high inoxidizability, demulsibility and rust and corrosion resistance, low carbon deposit, and high hydrolytic stability; the extreme-pressure antifriction micropowder can reduce the frictional coefficient, an easy-to-cut film is formed on a frictional surface, the frictional surface is filled up and repaired to some extent, and the antifriction effect is achieved; the composite emulsion-resistant agents, no matter with low concentration or high concentration, have emulsion resistance effect and high rust prevention performance, the preparation process is simple, and the environment is friendly.

Description

technical field [0001] The invention relates to the technical field of industrial compressor oil, in particular to a composite air compressor oil composition and a preparation method thereof. Background technique [0002] Compressor oils have long been used to lubricate compressor bearings, seal rotors, and cool compressed air. Therefore, the lubricating oil required should have excellent oxidation stability, thermal stability, hydrolytic stability, low carbon deposition and sludge formation tendency, good oil-water separation and excellent anti-rust performance, etc. The quality of compressor oil has a great impact on the reliability and safety of the compressor, and good oil can effectively reduce the oil change cycle and prolong the service life of oil and equipment. Compressor oils currently on the market are usually divided into mineral type and synthetic type. Mineral type compressor oil has a short service life, while fully synthetic type compressor oil has a long se...
