Problems solved by technology

However, polyalphaolefin has poor lubricity; although ester oil has certain lubricating properties, it has poor hydrolysis stability and is easy to decompose when exposed to water.
It is shown in the patent (US4302343) that ester compressor oil is more suitable for reciprocating compressors, and its low-temperature viscosity is relatively high in screw compressors, which is not conducive to low-temperature start-up

Abstract

The invention provides polyether type total-synthesis compressor oil composite which is prepared from the following ingredients in weight percentage: 60%to 85% of polyether, 5% to 30%of alkyl aromatics, 0.5% to 8% of antioxidant, 0.01% to 1% of sulfur-containing or phosphorus-containing extreme-pressure anti-wear agent, 0.01% to 1% of antirust agent, 0.001% to 0.5%of metal passivating agent and 0.001% to 0.1% of demulsifying agent. The invention further provides a preparation method of the polyether type total-synthesis compressor oil composition. The polyether type total-synthesis compressor oil composition has excellent oxidation stability and thermal stability, also has excellent detergency and dispersibility, low carbon deposite and oil sludge formation inclination and excellent hydrolysis stability and demulsibility and is especially suitable for lubricating high-temperature and high-pressure worm air compressors.

Description

technical field [0001] The invention relates to the technical field of industrial compressor oil, in particular to a polyether type fully synthetic compressor oil composition used for lubricating screw air compressors. Background technique [0002] Compressor oils have long been used to lubricate compressor bearings, seal rotors, and cool compressed air. Since the air compressor is always under the condition of high pressure, high temperature and condensed water, the required lubricating oil should have excellent oxidation stability, thermal stability, low carbon deposition and sludge formation tendency, good oil-water separation and Excellent rust resistance, 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. [0003] Compressor oils currently on the market are usually divided into mineral type and synthetic type. ...
