摘要（英）：

The invention discloses an air compressor oil composition. A lubricating oil composition contains the following components in percentage by weight: 85wt%-99wt% of base lubricating oil, 0.01wt%-10wt% of an antioxidant multi-effect additive, 0.01wt%-5wt% of 2,2'-thio-bis[3-(3,5-ditert-butyl-4-hydroxyphenyl)propionate, 0.02wt%-5wt% of zinc oxide nano-particles and 0.01wt%-5wt% of a pour point depressant. Compressor oil prepared from the lubricating oil composition has excellent oxidation stability, high-temperature stability, liquid-phase anti-rusting property and water diversion property. The antioxidant multi-effect additive is a compound represented by a formula (I) (shown in the description). The invention further provides a preparation method of the air compressor oil composition. The air compressor oil composition has excellent wear resistance and oxidation resistance and can be widely applied to the field of lubricating oil of air compressors.
