Description
Technical Field
The invention relates to lubricating oil, in particular to an air compressor lubricating oil composition and a preparation method thereof.
Background
The air compressor is a universal mechanical device, can provide power and process gas, and is widely applied in the industry. With the development of air compressor technology, higher requirements are being placed on the performance of air compressor lubricating oils. For the recycled air compressor lubricating oil, the lubricating oil needs to have stronger high-temperature oxidation resistance and extreme pressure wear resistance. Compared with mineral air compressor lubricating oil, the synthetic air compressor oil has the advantages of good high-low temperature performance, long service life, high cost performance, capability of improving the operation safety coefficient of the compressor, less environmental pollution and the like, can better adapt to the use and the needs of a novel compressor, and also has the problems of short oil change period, poor high-temperature oxidation resistance and the like.
In the air compressor lubricant oil, antioxidants used mainly include phenol type, amine type, phenol ester type, thioester type, phosphite type and the like, among which hindered phenol type antioxidants are widely used. For example, CN 113088368, CN 92102699, CN 99811367, USP 5124057, USP 6207623, USP 6410490 and the like all use hindered phenol type antioxidants as one of the antioxidant components thereof, but it is difficult to satisfy the requirement of long life with general hindered phenol type antioxidants. There remains a need in the art for air compressor lubricating oil compositions that have long life and excellent oxidation stability and antiwear properties.

Detailed Description
In this specification, the term "single bond" is sometimes used in the definition of a group. By "single bond" is meant that the group is absent. For example, assume the structural formula-CH 2-A-CH3, wherein the group a is defined as selected from single bonds and methyl. In view of this, if A is a single bond, this means that the group A is absent, in which case the formula is correspondingly reduced to-CH 2-CH3.
In the context of the present specification, the expression "number +valence +group" or the like means a group obtained by removing the number of hydrogen atoms represented by the number from a basic structure (such as a chain, a ring, or a combination thereof, etc.) to which the group corresponds, preferably a group obtained by removing the number of hydrogen atoms represented by the number from carbon atoms (preferably saturated carbon atoms and/or non-identical carbon atoms) contained in the structure. For example, "3-valent linear or branched alkyl group" refers to a group obtained by removing 3 hydrogen atoms from a linear or branched alkane (i.e., the basic chain to which the linear or branched alkyl group corresponds).
