Problems solved by technology

However, it is difficult for the compressor lubricating oil on the market to meet the above-mentioned work requirements. Even if the compressor lubricating oil can barely meet the above-mentioned requirements, it is difficult to achieve stability at high temperatures, because some high-pressure reciprocating compressors are under working conditions. , its gas release temperature can reach between 80-110°C
Compressor lubricants must therefore minimize the generation of large amounts of carbon deposits in the hot valve area, as large deposits of carbon deposits increase the risk of fire and explosion
However, the prices of research institutes and lubricating oils with good functions on the market are relatively expensive.

Abstract

The invention relates to a composite additive special for compressor oil. The composite additive is basically characterized by comprising, by weight, 5% of polyisobutylene dibutyl imide, 4.5% of sterically hindered phenol, 3.5% of ethoxy phenol, 3.5% of a toluyl triazole derivative, 12% of a dialkyl dithiocarbamic acid metal salt, 3.5% of polyalkoxy phenol, 4% of a styrene propylene copolymer, 4% of polyacrylic ester, and the balance base oil. The making method of the composite additive is simple, feasible, economical and practical, and the prepared compressor lubricating oil additive is low in cost, and has corrosion resistance, oxidation resistance and strong thermal stability to various compressor lubricating oil. The viscosity index can be maintained for a long time, the wear resistance is obviously enhanced, and gas sealing and long-term lubrication of the compressor can be provided, the composite additive has no corrosion to the inside of the compressor and can maintain the clean effect of the compressor lubricating oil for a long time. The waste oil is degradable, thus improving the environmental protection requirements.

Description

(1) Technical field [0001] The invention relates to a compressor oil additive, in particular to a special composite additive for compressor oil. (2) Background technology [0002] Because of the lubrication requirements of the compressor, the lubrication requirements of the compressor depend on many parameters of the actual situation, such as the type of compressor, the compression ratio of the gas, and the designed release temperature and pressure. According to the process of compressing gas, compressors can be divided into two categories, but no matter which type of compressor requires lubricating oil, it must have oxidation resistance, thermal stability, viscosity retention, and anti-wear characteristics to provide protection against gas. of the seal. As well as general lubricating oil and anti-corrosion properties. However, it is difficult for the compressor lubricating oil on the market to meet the above-mentioned work requirements. Even if the compressor lubricating ...
