Description
Technical field
The invention belongs to technical field of lubricating oil, and in particular to a kind of synthesis refrigerator oil and preparation method thereof.
Background technology
Refrigerator oil, which is mainly used for lubricating in refrigerator, needs the position lubricated, with compressor operating performance and used life
There is substantial connection, so its selection and application, are all very important.It is different from plain oil, refrigerator oil and refrigeration
Agent continuously recycles between the evaporator of the compressor outlet of high-temperature region to low-temperature space together, and operating temperature range is very wide, therefore
In addition to requiring refrigerator oil that there is good lubrication, sealing, cooling and Corrosion Protection, more require it in low temperature to the big model of high temperature
There are good dissolubility and adaptability with refrigerant in enclosing.
In fluoroether refrigerant, HFC-134a, R407C, R410A are typically used as used for automobile air conditioning, refrigerator use or indoor
Air-conditioning refrigeration agent.But although these fluoroether refrigerant ozone destruction coefficients are zero, greenhouse effects of the earth coefficient is high, institute
More to become the object of limitation.Therefore, exploitation substitutes the refrigerant of hydrofluorocarbon as the task of top priority.
The features such as difluoromethane refrigerant is free of chlorine, and has lower greenhouse effects of the earth coefficient, and environmentally friendly efficiency is high, gradually at
For novel refrigerant.Currently, the refrigerator oil for being widely used in hydrogen fluorohydrocarbon class refrigerant is difficult to mix with difluoromethane.
Invention content
In order to overcome the deficiencies of the prior art, refrigerated machine oil composition provided by the present invention has good oxidation stable
Property, anti-friction, and it is good with hydrocarbon refrigerant intermiscibility.
To achieve the above object, the invention is realized by the following technical scheme.
A kind of synthesis refrigerator oil, including polyol ester and additive：Additive includes antioxidant, sour agent for capturing, defoaming
Agent, copper inhibitor；Wherein, the content of polyol ester is the 90% ~ 99% of the refrigerator oil gross mass；The content of antioxidant is institute
State the 0.1% ~ 2% of refrigerator oil gross mass；The content of sour agent for capturing is the 0.01% ~ 1% of the refrigerator oil gross mass；Antifoaming agent
Content be the refrigerator oil gross mass 0.01% ~ 1%；The content of copper inhibitor is the 0.1% of the refrigerator oil gross mass
~2%。
The polyol ester be neopentyl glycol ester, pentaerythritol ester and pentaerythritol fatty acid ester in any one or at least
Two kinds of composition.
The polyol ester is polyalcohol and aliphatic acid through obtained by esterification；Wherein, polyalcohol is neopentyl glycol, season
In penta tetrol and dipentaerythritol any one or at least two composition, the aliphatic acid is the fat that carbon number is 5 ~ 10
Fat acid.
The antioxidant is DBPC 2,6 ditertiary butyl p cresol.
The sour agent for capturing is tert-butyl-phenyl glycidol ether.
The antifoaming agent is polyether modified silicon oil.
The copper inhibitor is benzotriazole.
Beneficial effects of the present invention：Refrigerated machine oil composition provided by the present invention has good oxidation stability, resists
Tribology, and it is good with hydrocarbon refrigerant intermiscibility.
Specific implementation method
Following case study on implementation, the present invention is further described in detail.

Sour, positive enanthic acid is through obtained by esterification.Refrigerator oil and difluoromethane low temperature two separate temperature after testing（10% oil content）
It is -29 DEG C, -42 DEG C of pour point.
Embodiment two
A kind of synthesis refrigerator oil, calculates, including following components according to weight percent：：Additive level is antioxidant 0.8%,
Sour agent for capturing 0.5%, antifoaming agent 0.1%, copper inhibitor 0.5%, surplus polyol ester.Wherein polyol ester is neopentyl glycol and different
Octanoic acid, valeric acid are through obtained by esterification.Refrigerator oil and difluoromethane low temperature two separate temperature after testing（10% oil content）
It is -31 DEG C, -48 DEG C of pour point.
Embodiment three
A kind of synthesis refrigerator oil, calculates, including following components according to weight percent：：Additive level is antioxidant 0.5%,
Sour agent for capturing 0.5%, antifoaming agent 0.5%, copper inhibitor 0.5%, surplus polyol ester.Wherein polyol ester is neopentyl glycol and different
N-nonanoic acid, positive enanthic acid are through obtained by esterification.Refrigerator oil and difluoromethane low temperature two separate temperature after testing（10% oil content）
It is -33 DEG C, -45 DEG C of pour point.
To sum up, refrigerator oil provided in an embodiment of the present invention has good intermiscibility with difluoromethane refrigerant, and cold
Freezing machine oil itself has good lubricating oil and low temperature flow.
Presented above is only the preferred embodiment of the present invention, it is noted that those skilled in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these also should be regarded as the protection model of invention
Within enclosing.
