Abstract

The invention provides environment-friendly synthetic ester air compressor oil. The oil is prepared from modified vegetable oil, synthetic ester, a high-temperature antioxidant, an antirust agent, anantiwear agent, a pour point reducer and an antifoaming agent, wherein the mass percent of the modified vegetable oil in the air compressor oil is 45-50%, the mass percent of the synthetic ester in the air compressor oil is 45-50%, the mass percent of the high-temperature antioxidant in the air compressor oil is 1-2%, the mass percent of the antirust agent in the air compressor oil is 1-2%, the mass percent of the antiwear agent in the air compressor oil is 1-2%, the mass percent of the pour point reducer in the air compressor oil is 1-2%, and the anti-foaming agent is 50-100 ppm. The invention further provides a preparation method of the air compressor oil. According to the environment-friendly synthetic ester air compressor oil, the open flash point can be up to 300-350 DEG C, the pour point is minus 45 DEG C or lower, the service life can be up to 10,000 h or more, and the rotary oxygen bomb time is 3,000 min or more.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to an air compressor oil, in particular to an environment-friendly synthetic ester air compressor oil and a preparation method thereof. Background technique [0002] Air compressor oil refers to the lubrication of the moving parts of the air compressor cylinder and the exhaust valve during operation, so as to effectively protect the screw, bearing, gear and other components, and to cool the parts through oil circulation, prevent rust and It is a type of oil that is used for cleaning and sealing the screw and the shell at the same time. Since the air compressor is always in the environment of high pressure, high temperature and condensed water, the air compressor oil should have excellent high temperature oxidation resistance, low carbon deposition tendency, excellent viscosity-temperature performance, good oil-water separability and Anti-rust performance. At present, air compressor o...
