Abstract

The invention discloses composite synthetic air compressor oil comprising the following components: a promoter, diisoalkyl (C8 to C13) linear dibasic ester, poly-alpha-olefin synthetic oil and diisoalkyl (C8 to C13) phthalate esters, wherein, the composite synthetic air compressor oil contains 15% to 20% of diisoalkyl (C8 to C13) linear dibasic ester by weight, 5% to 10% of poly-alpha-olefin synthetic oil by weight and 72% to 74% of diisoalkyl (C8 to C13) phthalate esters by weight. The composite synthetic air compressor oil of the invention can meet the requirements that the carbon residue value thereof is low and the biodegradation rate is higher than 70%; the composite synthetic air compressor oil has high high-temperature anti-oxidation stability, lubricating properties, rust-preventing properties, foam resistance and emulsion resistance; and the invention has the advantages that the energy is saved, the environmental pollution is reduced and the service life is prolonged, therefore, the invention can fully satisfy the operating requirements for rotary-type screw compressors.

Description

technical field [0001] The invention relates to a fully synthetic lubricating oil, in particular to an air compressor, in particular to a fully synthetic lubricating oil for screw air compressors. Background technique [0002] Air compressors are general-purpose machinery widely used in various fields of national economy and industry, and the consumption and production volume are quite large. The annual consumption of compressor oil in my country is nearly 100,000 tons. At present, the air compressor oil in our country is still dominated by mineral oil, accounting for more than 80%, while the air compressor is mainly reciprocating. With the development of industrial technology, the use of mineral compressor oil in reciprocating air compressors has increasingly exposed serious shortcomings, the main manifestations are: short service life (generally 1000h); fire and explosion safety accidents are prone to occur; serious environmental pollution (noise , exhaust, waste oil disc...
