Abstract

The invention relates to an air compressor oil composition and a preparing method thereof. The air compressor oil composition comprises the following ingredients: A, base oil consisting of ester oil and PAO (Polyalphaolefin) oil; B, antioxidant consisting of an amine antioxidant and dialkyl dithiocarbamate ester; C, at least one oiliness additive; D, at least one high-viscosity complex ester compound; E, at least one metal passivator; F, at least one emulsion breaker; G, at least one antifoamer. The air compressor oil composition has the advantages of environment-friendliness, capability of saving energy and reducing consumption and excellent oxidation resistance. The invention further relates to the preparing method of the air compressor oil composition.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to an air compressor oil composition which is environmentally friendly, capable of saving energy and reducing consumption, and has good oxidation resistance and a preparation method thereof. Background technique [0002] At present, the air compressor oil in our country is still dominated by mineral oil, accounting for more than 80%. Mineral compressor oil is a blend of oil after a series of fractionation, purification, refining, and additives; due to its extremely low biodegradability , so it is difficult to decompose in nature, causing increasingly serious pollution to the natural environment. With the development of industrial technology, the use of mineral oil in air compressors has increasingly exposed serious shortcomings, mainly manifested in: short service life, serious environmental pollution (noise, exhaust, waste oil discharge), high energy consumption, frequent...
