Description

technical field [0001] The invention relates to the field of chemistry, in particular to organic chemistry, in particular to air compressor oil, in particular to an air compressor oil and a preparation method thereof. Background technique [0002] An air compressor is a machine that provides a source of air power, and it involves various fields of the national economy including machinery, road and bridge construction, mining, pharmaceutical production, and chemical production. Air compressors in the prior art have two types: reciprocating compressors and screw compressors, and screw compressors are further divided into single-screw and twin-screw compressors. Regardless of the type of machine, air compressor oil is required. Air compressor oil is mainly used for lubricating the moving parts of the air compressor cylinder and the exhaust valve during operation, and plays the role of antirust, anticorrosion, sealing and cooling to effectively protect the screw, bearings, gear...
