Problems solved by technology

[0004] At present, the compressor oil in my country is still dominated by mineral oil. With the continuous acceleration of industrial modernization, the use of mineral oil in compressors has increasingly exposed serious shortcomings, such as short service life, fire and explosion safety accidents, and environmental pollution. Serious, high energy consumption, frequent oil changes and failures, seriously affecting production efficiency, and the use of ester synthetic oil can basically solve the above problems

Abstract

The invention relates to a preparation method of a synthetic screw air compressor oil. The preparation method comprises the following steps: mixing 22-23 parts of trimethylolpropane with 13-15 parts of butane diacid, or mixing 44-46 parts of trimethylolpropane with 13-15 parts of acrylic acid, or mixing 44-46 parts of trimethylolpropane with 13-15 parts of octanoic acid to form ester A; mixing 31-35 parts of glycol with 31-35 parts of butane diacid to form ester B; mixing 31-43 parts of glycol with 15.5-21.5 parts of acrylic acid to form ester C; mixing 31-38 parts of glycol with 15.5-19 parts of octanoic acid to form ester D; further mixing 43-44 parts of the mixed ester A with 43-44 parts of the mixed ester B; mixing 42-43 parts of the mixed ester A with 42-45 parts of the mixed ester C; mixing 47-49 parts of the mixed ester A with 36-38 parts of the mixed ester D; mixing 30-32 parts of the mixed ester B, 30-32 parts of the mixed ester C with 30-32 parts of the mixed ester D to prepare a base oil; and taking 44-46 parts of base oil and 4-56 parts of complex ingredients to prepare the finished product oil.

Description

technical field [0001] The invention relates to an air compressor lubricating oil, especially a lubricating oil suitable for a screw air compressor system. The product has good anti-corrosion, anti-rust, anti-wear, anti-emulsification and anti-oxidation properties. Background technique [0002] Compressor is a general-purpose machine widely used in various fields of industry. Compressor lubricating oil is regarded as the "blood" of the compressor. Therefore, the selection and manufacture of high-performance and high-quality lubricating oil will enable the compressor system equipment to be able to operate smoothly during use. Whether it is the key technical link of energy saving and consumption reduction. [0003] According to literature disclosure: [1] Patent CN 201010613297 discloses an ultra-high pressure ethylene compressor oil, which includes the following components by weight percentage: polyether synthetic oil: 93-99%; antioxidant: 0.1-2%; antirust Agent: 0-5%.
