Abstract

The invention belongs to the technical field of refrigerator oil, and provides a cold work refrigerator oil additive, which comprises the following raw materials in parts by weight: 23-40 parts of anaromatic hydrocarbon diluent, 10-15 parts of an antioxidant, 5-8 parts of an extreme pressure anti-wear agent, 1-3 parts of a metal deactivator and 0.12-0.16 part of a defoaming agent; wherein the aromatic hydrocarbon diluent is heavy alkyl benzene, the antioxidant is octyl/butyl diphenylamine, the extreme pressure anti-wear agent is triphenyl thiophosphate, the metal deactivator is benzotriazole,and the defoaming agent is polyalkylene glycol. The preparation method is simple, the proportion is reasonable, and after the additive is added into the refrigerator oil, the refrigerator oil can have the refrigerant compatibility, lubricity and low-temperature fluidity.

Description

technical field [0001] The invention relates to the technical field of refrigerating machine oil, in particular to a cold-power refrigerating machine oil additive. Background technique [0002] The working principle of the compression refrigeration system is to use the refrigerant to vaporize and volatilize, absorb the heat of the surrounding medium, reduce the temperature for cooling, and then compress the refrigerant through the compressor, liquefy the condenser to dissipate heat, and then re-gasify, and so on. . The compressor is the key to this kind of refrigeration system. The refrigeration oil plays the roles of lubrication, heat dissipation, sealing and anticorrosion in the compressor, which has a significant impact on the efficiency of the refrigeration system and the life of the compressor. It is very important for compression refrigeration system. The large-scale screw refrigeration compressor unit using ammonia as the refrigerant has a large refrigeration load a...
