The invention relates to a screw type air compressor oil composition, by calculating the weight of base oil as 100%, the screw type air compressor oil composition comprises the following components: 1-5% of high temperature anti-oxidant, 0.01-5% of extreme-pressure anti-grinding agent, 0.01-0.5% of corrosion resistance agent and 0.01-0.5% of antirust agent, wherein the high temperature anti-oxidant is composed of an amine type anti-oxidant, a phenol type anti-oxidant and a phosphite type anti-oxidant, and the weight ratio of amine type anti-oxidant to phenol type anti-oxidant to phosphite type anti-oxidant is 20: 30: 50-50: 30: 20; the phosphite type anti-oxidant is introduced in the screw compressor oil, and is synergized with the phenol or amine type anti-oxidant, compared with a common amine and phenol type anti-oxidant system, the antioxidation performance of the oil product can be greatly increased, the oil sludge generation trend can be better controlled, and the composition is suitable for the screw compressor oil which takes hydrogenation oil, PAO synthetic oil and semi-synthetic oil as base oil.
Description
technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition which has good oxidation resistance, can reduce the tendency of sludge formation, and is suitable for screw air compressors. Background technique [0002] A compressor is a machine used to compress gas, increase the pressure of gas or transport gas. With the development of production technology, the types and structural forms of compressors are increasing day by day. Nowadays, compressors of various types and specifications are widely used in petrochemical, machinery manufacturing, civil engineering, mining and metallurgy, transportation, national defense, medical, textile and food and other fields. The screw air compressor that dominates the compressor, the lubricating oil used is in high temperature and high pressure environment in contact with the air for a long time, the lubricating oil is easily oxidized, causing the viscosity, acid value and sl...
