Abstract

The invention discloses an air compressor lubricating oil composition with strong oxidation resistance. The air compressor lubricating oil composition with the strong oxidation resistance comprises the following components in parts by mass: 90-95 parts of synthetic base oil, 0.01-0.03 parts of a demulsifying agent, 0.3-0.5 parts of an anti-wear agent, 1-2 parts of bis(4-(2,4,4-trimethyl-2-pentyl)phenyl)amine, 0.5-1 part of bis(3,5-di-tert-butyl)phosphine oxide, and 1.5-2 parts of 2,2'-methylene bis(4,6-di-t-butylphenol). A preparation method comprises the following steps of firstly mixing thebis(4-(2,4,4-trimethyl-2-pentyl)phenyl)amine, the bis(3,5-di-tert-butyl)phosphine oxide and the 2,2'-methylene bis(4,6-di-t-butylphenol); secondly adding other components except the synthetic base oil, and mixing the components to form an intermediate mixture; thirdly heating the synthetic base oil to 45-50 DEG C; and finally mixing and uniformly stirring the intermediate mixture and the syntheticbase oil. The air compressor lubricating oil composition has the advantages that the antioxidant performance of lubricating oil is enhanced, so that the service life of the lubricating oil is prolonged.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to an air compressor lubricating oil composition with strong oxidation resistance. Background technique [0002] Air compressor lubricating oil is a liquid lubricant used on various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. The role of air compressor lubricating oil is to form a protective film between the two friction pairs to avoid direct contact between metal and metal, thereby buffering the effect of friction, lubricating, reducing wear, and making the machine operate normally. [0003] Air compressor lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil for air compressors, which determines the basic properties of lubricating oil; additives are the essence of modern high-gr...
