Drying-free refrigerant compatible air-conditioning copper pipe elbow processing oil and preparation method thereof

Abstract

The invention discloses drying-free refrigerant compatibility air-conditioning copper pipe elbow processing oil and a preparation method thereof. The method comprises the following steps: adding base oil into a reaction kettle, raising the temperature to be 40+ / -5 DEG C, preserving the temperature for 10+ / -5 minutes, adding an antioxidant additive, stirring until the liquid is transparent, and controlling the temperature to be 40+ / -5 DEG C in the stirring process, wherein the stirring time is 30+ / -5 minutes, the base oil accounts for 97-100 percent of the total weight, the antioxidant additive accounts for 0-3 percent of the total weight and adopts 4,4'-diisopropyl phenyl diphenylamine, and the base oil adopts low-viscosity ester base oil with specific specification parameters. The drying-free refrigerant compatibility air-conditioning copper pipe elbow processing oil has drying-free characteristics, has the compatible characteristics of all refrigerants and compressor oil, the processing requirements of the air-conditioning elbow are met, the use amount of oil is saved, the natural gas, equipment, electricity, manual labor and land used by drying are saved, carbon dioxide emitted into the environment due to natural gas combustion is reduced, and obvious economy is brought to customers.

Description

technical field [0001] The invention relates to a processing oil required to ensure lubricity during the production of air-conditioning copper pipe elbows (U-shaped pipes), especially a drying-free (degreasing-free) type air-conditioning copper that is compatible with refrigerants and compressor oils. Pipe bending oil. Background technique [0002] In the development process of elbow oil, it has developed from cleanable to no-cleaning, and then to drying and degreasing type. Most of the oils used in the market are drying type. After the copper pipe bending process is completed, there is volatile oil inside the copper pipe. If there are product residues, it needs to be dried in a degreasing furnace to completely volatilize the volatile oil in the tube. The purpose is to avoid affecting the energy efficiency ratio of the air conditioner and the ant nest corrosion of the subsequent copper tubes. Natural gas, electricity, personnel and sites for drying are consumed during the e...

AI Technical Summary

Problems solved by technology

Natural gas, electricity, personnel and sites for drying are consumed during the entire process.

This kind of drying and degreasing type product obviously improves the corresponding ant nest corrosion phenomenon after the whole air-conditioning copper pipe is manufactured. The disadvantage is that the whole processing process consumes a lot of energy, and also increases the carbon dioxide emitted into the environment by the combustion of natural gas. , did not fully realize energy saving and environmental protection
