Abstract

The invention belongs to the technical field of mechanical lubrication, particularly relates to synthetic refrigerating machine oil and a preparation method thereof, and solves the problems of higher pour point, poor dispersion stability, poor viscosity and the like of refrigerating machine oil in the prior art. The refrigerating machine oil comprises the following raw materials in percentage by weight: 10 to 50 percent of naphthenic base oil, 48 to 88 percent of alkylbenzene oil, 1.5 to 2.5 percent of additive and the balance of defoaming agent. According to the invention, the naphthenic base oil with excellent low-temperature performance and good solubility is adopted; and the alkyl benzene oil with a low pour point and good low-temperature fluidity is adopted as a main raw material, and the alkyl benzene oil and the naphthenic base oil are highly soluble by selecting a reasonable ratio. The obtained refrigerating machine oil is appropriate in viscosity, excellent in low-temperature performance, hydrolytic stability and solubility and good in compatibility with mineral oil and ester oil. The preparation method is simple, adopts a pulse blending treatment technology, and is efficient, energy-saving, easy for industrial production and widely applicable.

Description

technical field [0001] The invention relates to the technical field of mechanical lubrication, in particular to a synthetic refrigerating machine oil and a preparation method thereof. Background technique [0002] Refrigeration oil is used in the moving parts of the refrigeration compressor, mainly for the functions of lubrication, sealing, cooling and energy regulation, also known as lubricating oil. Refrigeration oil is an essential medium in the refrigeration system, especially plays a key role in the operation of the Freon refrigeration system. Among many refrigeration systems, the accident rate of compressor failure and poor operation of the refrigeration system due to lack of oil and poor lubrication is the highest. Therefore, practitioners in the refrigeration industry should pay special attention to refrigeration oil during design and use. Refrigeration oil is used in refrigeration systems. It must not only have the characteristics of general mechanical lubricants, ...
