Abstract

The present invention relates to a synthetic compressor lubricating oil composition and a production method thereof. The synthetic compressor lubricating oil composition is prepared by mixing the following raw materials, by weight, 80-90 parts of a liquid A and 10-20 parts of a liquid B, wherein the liquid A is prepared by mixing one or a plurality of poly alpha-olefin synthetic base oil with different viscosities, and the liquid B is prepared by mixing the following additives, by weight, 5.0-15.0 parts of an ester, 0.05-2 parts of an antioxidant, 0.01-2 parts of a rust inhibitor, 0.01-0.5 part of a metal deactivator, 0.5-3 parts of an extreme pressure wear resistance agent, 0.005-0.05 part of anti-emulsification agent, and 0.003-0.01 part of an anti-foaming agent. According to the present invention, stability is high, an oil change period is long, compressor energy consumption can be substantially reduced, a service life of the compressor can be prolonged, significant economic and social benefits are provided, and environmental pollution can not be caused.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a synthetic compressor lubricating oil composition and a preparation method thereof. Background technique [0002] Compressor oil is a special lubricating oil. Its function is to form a lubricating oil film on the friction surface of the relative movement of the compressor, reduce friction and wear, and reduce energy consumption. It is mainly used for the friction parts of the piston and cylinder of the compressor and Lubricate the intake and exhaust valves, main bearings, connecting rod bearings and other transmission parts, and also play the role of cooling the friction surface of moving parts and the working volume of sealed gas compression. Commonly referred to as compressor oil only refers to lubricating oil used for cylinder lubrication of reciprocating and rotary compressors. Since the compressor is always in the environment of high pressure, high temperature and con...
