Abstract

The invention provides a refrigerating machine oil additive and refrigerating machine oil. In the structural formula of the refrigerating machine oil additive, R1 is alkyl with the carbon atom number of 1-8; and R2 is alkyl with the carbon atom number of 1-8. In the structural formula of the refrigerating machine oil additive, N-P bonds and a specific benzotriazole chemical structure exist, a chemical protection film can be formed on the surface of a metal material, metal particles are prevented from being automatically oxidized and catalyzed, corrosion of the metal material is delayed, active P atoms are contained in the structure, the anti-wear effect of refrigerating machine oil can be achieved, therefore, the effect of delaying corrosion of compressor metal materials to resist abrasion can be achieved.

Description

technical field [0001] The application belongs to the technical field of refrigerating machine oil, and in particular relates to a refrigerating machine oil additive and refrigerating machine oil. Background technique [0002] The development process of refrigerants has always been carried out around two aspects: environmental safety performance and refrigeration performance. CFC (Chlorofluorocarbons) and HCFCs (Hydrochlorofluorocarbons), which have been used as refrigerants for refrigerators so far, have been restricted due to the destruction of the earth's ozone layer due to their chlorine elements. Hydrofluorocarbons with environmental protection, non-toxic, and good stability (HFCs) have become the main focus and are currently one of the more ideal refrigerants. [0003] At the same time, refrigerating machine oil, which is closely related to refrigerants, has also developed from the original mineral oil to the current synthetic oil. Ester synthetic oil, mostly obtaine...
