Problems solved by technology

However, no demulsifier is added in the modified patent. During the rainy season, the moisture content in the air is high, and the moisture is easily mixed into the air compressor. If the moisture is separated slowly, it is easy to cause oil emulsification and accelerate oil emulsification.
[0007] Patent 201310139247.7 "Air Compressor Oil Composition and Its Preparation Method" discloses an air compressor oil composition and its preparation method, including the following components and percentage content: polyether oil-based base oil or polyether oil and esters Combination of oil mixture base oil and 2,2,4-trialkyl-1,2 dihydroquinoline antioxidant and metal deactivator, the air compressor oil has good oxidation stability and simple preparation characteristics, but only one type of antioxidant is used in the modified invention, and the antioxidant effect is not as good as that of different types of antioxidants.

Abstract

The invention relates to the field of lubricating oil, and discloses high oxidation resistance long-life complete synthesis screw air compressor oil and a preparation method thereof. The oil comprisesthe following components in mass percent: 0.8 to 4 percent of at least two antioxidants, 0.05 to 1 percent of at least one metal deactivator, 0.1 to 1 percent of at least ashless anti-wear additive,0.005 to 0.1 percent of at least one defoaming agent, 0.001 to 0.1 percent of at least one demulsifier, and at least one synthetic base oil for the surplus. Saturated polyol ester and polyether in theoil has good cleaning and purifying effects on oil sludge, further prevents the production of colloid and prevents carbon deposition from being produced in the air compressor oil. As PAO oil does nothave the effect of oil sludge dispersion, when the PAO oil is selected as base oil, the saturated polyol ester and oil-soluble polyether are supplemented to be as solubilizers to dissolve and disperse the oil sludge.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a fully synthetic screw air compressor oil with high oxidation resistance and long service life and a preparation method thereof. Background technique [0002] The current screw air compressors are mainly developed in the direction of high speed, heavy load, and high thermal intensity, and also in the direction of small and light weight, standardized components, high efficiency, and low noise. This puts forward higher requirements for screw air compressor oils such as high oxidation stability, heat resistance stability, low carbon deposition, and long life. [0003] Because the screw air compressor oil prepared with paraffinic base oil is not stable in oxidation during use, it is easy to produce various organic acids, colloids, asphalt and other substances, which are easy to be on the exhaust system of the screw air compressor. A large amount of carbon deposits are generated, whic...
