Background technology
Compression-type refrigerating system is made up of refrigeration compressor, condenser, expansion valve, evaporator etc., and operation principle is to utilize
When refrigerant vapor volatilizees, the heat of surrounding medium is absorbed, temperature is reduced and is cooled down, then by compressor by refrigerant
Liquid is restored to, then is gasified again, is so moved in circles.This refrigeration system is largely used to the household electrical appliance such as refrigerator, air-conditioning, cold
The business machine such as the industrial equipments such as storehouse, refrigerating chamber and showcase, beverage, ice cream maker.Compressor is above-mentioned compression-type refrigeration system
The heart of system, and the refrigerator oil for playing lubrication, radiating, sealing and anti-corrosion etc. in compressor is then to compressor and refrigeration
The performance of system plays and there is highly important influence in the life-span, therefore selects the refrigerator oil of excellent performance to compression refrigerating system
For be highly important.
In refrigerator compressor industry, with 1,1,1,2 HFC-134a（R134a）For the refrigeration that hfc refrigerant is representative
Machine will not damage the ozone layer, and be widely used as compression-type refrigerating machine refrigerant.And matched synthesis refrigerator oil
Product is although lubricity, compatibility, and heat/chemically stable sex expression can meet the compressor operatings such as domestic refrigerator and industrial refrigeration
The requirement of aspect, but in some special refrigeration application fields, it is desirable to oil product itself has good low temperature flow, simultaneously
The good lubricating properties of compressor operating can be ensured, this requires oil product to have (＜ -70 DEG C very low of pour point）, while have one
Fixed viscosity level ensures compressor lubrication.Most of existing fully synthetic POE refrigerator oils structure is pentaerythrite and fat
The pentaerythritol fatty ester and nitration mixture ester that fat acid is formed（Aliphatic acid carbon number is in the range of 5~9）, lubricity, compatibility, heat/
Chemical stability reaches compressor operating requirement, but pour point can not meet to require;Itd is proposed in face of refrigeration compressor design
Requirements at the higher level, it is necessary to developed to existing fully synthetic refrigerator oil.
The content of the invention
The present invention proposes a kind of refrigerated machine oil composition, and the refrigerated machine oil composition has good lubricity and refrigerant

Freeze the aliphatic acid that machine oil base oil is neopentyl glycol and carbon number is C4~C6 and be prepared the one of neopentyl glycol fatty acid ester
Kind is a variety of.
In further some embodiments of the invention, the refrigerated machine oil composition 40 DEG C of kinematic viscosity 8~
24mm2/s。
Further, the pour point of the refrigerated machine oil composition is below -70 DEG C.
Further, antioxidant is also contained in the refrigerated machine oil composition, antiwear additive, corrosion inhibitor, in sour agent for capturing
One or more.
The refrigerator oil base oil I of present invention preparation method：
Under nitrogen or argon, condensing reflux, by aliphatic acid that pentaerythrite and carbon number are C4~C6 according to mole
Than being heated to 150~300 degree after mixing, 3~24 hours are incubated, reaction is completed.
Gained refrigerator oil base oil I can be extracted by molecular distillation and vacuum distillation, kieselguhr adsorption, washing and solvent
One or more in taking technique carry out refined purification.
The refrigerator oil base oil II of present invention preparation method：
Under nitrogen or argon, condensing reflux, by aliphatic acid that new penta tetrol and carbon number are C4~C6 according to mole
Than being heated to 150~300 degree after mixing, 3~24 hours are incubated, reaction is completed.
Gained refrigerator oil base oil II can be by molecular distillation and vacuum distillation, kieselguhr adsorption, washing and solvent
One or more in extraction process carry out refined purification.
A kind of preparation method of refrigerated machine oil composition is to press refrigerator oil base oil I and refrigerator oil base oil II
It is well mixed according to proportioning.
Beneficial effects of the present invention：
The refrigerated machine oil composition of the present invention has the compatibility and heat/chemical stability of good lubricity and refrigerant, simultaneously
Pour point is lower, reaches less than -70 DEG C, disclosure satisfy that special dimension refrigeration compressor proposes to fully synthetic refrigerator oil it is higher will
Ask.
