Problems solved by technology

[0008] Air compressor lubricating oil is mainly used for lubricating the moving parts of the compressor cylinder and the exhaust valve, and plays the role of antirust, anticorrosion, sealing and cooling. It is easy to emulsify, and the user experience is poor. If carbon deposition and emulsification can be effectively inhibited, the lubricating performance of the lubricating oil can be effectively improved

Abstract

The invention discloses an air compressor lubricating oil formula which is prepared from the following raw materials in parts by weight: 60-70 parts of fluoroterephthalyl alcohol difluorodecanoate, 10-20 parts of a liquid phenolic ester compound, 1-2 parts of a decarburizing agent, 5-10 parts of demulsifying agent, 1-3 parts of antioxidant, 0.3-1 part of anticorrosive agent, 0.3-1 part of pour point depressant, 1-2 parts of butyl stearate, 1-2 parts of alpha-olefin copolymer pour point depressant and 0.3-0.8 part of viscosity index improver. According to the invention, fluoroterephthalyl alcohol difluorodecanoate is used as a base oil component, the fluoroterephthalyl alcohol difluorodecanoate is high in fluorine content, excellent in high-temperature resistance and oxidation resistance, and not easy to oxidize and degrade at high temperature to generate carbon deposition, and the liquid phenolic ester compound is combined with the antioxidant, so that the function of inhibiting oxidation and carbon deposition formation can be achieved, and meanwhile, under the action of the demulsifying agent, the phenomenon that lubricating oil is emulsified in a low-temperature state can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an air compressor lubricating oil formula. Background technique [0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane or rotary screw. Centrifugal compressors are very large applications. [0003] There are many types of air compressors (air compressors). [0004] 1. According to the working principle, it can be divided into three categories: volumetric type, power type (speed type or turbine type), and thermal type compressor. [0005] 2. According to the lubrication method, it can be divided into oil-free air compressor and oil-lubricated air compressor. [0006] 3. According to the performance, it can be divided into: low noise, variable frequency, explosion-proof and other air compressors. [0007] 4. According to the purpose, it can be d...
