Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Oxygen and moisture invade a compressor system due to equipment or environmental factors, while mineral refrigeration oil slowly chemically reacts with water in the presence of moisture and an R22 refrigerant (R22 is a member of the freon family, and belongs to hydrochlorofluorocarbon refrigerant, and the refrigerant R22 is widely used in reciprocating compressors as a medium-low temperature refrigerant which is most widely used at present, and is used as a refrigerant of industrial, commercial and household air-conditioning systems), generates acid in a long-term state, and finally undergoes a reduction reaction with ferrous parts in the compressor to cause copper plating. The chemical reaction formula of the copper plating phenomenon is shown as formulas (1) and (2):
O2+4HCl+2Cu→2CuCl2+2H2O (1)
Fe+2CuCl2→FeCl2+2Cu↓ (2)
the copper generated by the reaction is deposited on the surface of the iron part, and the surface size of the part, such as surface roughness, can be changed by increasing the thickness of the copper film. Meanwhile, the fit clearance between the parts is influenced, so that the power consumption of the compressor is increased, and even the compressor is stuck to work continuously.
In view of the above problems, embodiments of the present invention relate to a refrigerating oil composition including a base oil, a metal chelator, and a dehydrating agent. The refrigerating oil composition can stably and normally run in a compressor, so that the refrigerating oil composition has refrigeration reliability.
In one embodiment of the invention, the base oil comprises a naphthenic mineral oil, such as a naphthenic mineral oil for HCFC refrigerants. Semi-synthetic or fully synthetic oils may also be selected, such as the base oils disclosed in prior art CN107353983A, which are obtained by polymerization of propylene oxide, or which are entrusted to a specialized company for synthesis.
In one embodiment of the invention, the metal chelating agent is selected from at least one of ethylenediaminetetraacetic acid (EDTA), citric acid, tartaric acid, nitrilotriacetic acid (NTA). The above metal chelating agents can be used, but the applicant has found that the stability of the complex formed by EDTA and metal ions is the best.
EDTA is a common metal ion chelating agent, and can perform a complex reaction with various metal ions including copper ions to form a stable ring structure, so that the reaction or harmful effect caused by the metal ions can be effectively reduced or inhibited. With EDTA as ligand, with Cu2+The reaction formula for forming the stable complex is shown as formula (3):
Cu2++Y4-＝[CuY]2-(Y represents EDTA) (3)
Due to the formation of stable complex ions [ CuY]2-The dissociation rate of the complex ion is low in dissociation equilibrium, thereby reducing Cu in the refrigerating oil composition2+The concentration of (3) results in a decrease in the reduction reaction rate shown by the formula (2), thereby preventing the progress of the copper plating reaction. The metal chelating agent can be 0.1-1.5 wt% of the refrigerating oil composition. Namely, the content of the metal chelating agent is 0.1 to 1.5 parts by weight relative to 100 parts by weight of the refrigerating oil composition.
The dehydrating agent used in the refrigerating oil composition of the present invention should be completely soluble in the base oil and not react with water to form acids, precipitates, and the like harmful to the compressor. Therefore, inorganic dehydrating agents such as calcium oxide cannot be used. In one embodiment of the invention, the dehydrating agent is Dimethoxypropane (DMP). DMP is a common liquid dehydrating agent, which can be dissolved in most organic solvents, and the chemical reaction formula of DMP with water is shown as formula (4):
CH3C(CH3O)2CH3+H2O＝2CH3OH+(CH3)2CO (4)
it can be seen that the reaction products of DMP with water are acetone and methanol, both of which are soluble in the base oil. Therefore, the DMP is selected to remove water in the refrigerating oil composition, so that the refrigerating oil composition can be effectively prevented from being degraded to generate acid, the reaction shown in the formula (1) is prevented from occurring, and copper plating is avoided. The mass percentage of the dehydrating agent in the refrigerating oil composition can be 1-2.5%. Namely, the content of the dehydrating agent is 1 to 2.5 parts by weight per 100 parts by weight of the refrigerating oil composition.
In one embodiment of the invention, the base oil may contain other additives in addition to the naphthenic mineral oil, such as antioxidants, acid scavengers, and antiwear agents.
Further, the base oil comprises the following components in parts by weight: 90 to 99 parts of naphthenic mineral oil, 0.1 to 3 parts of antioxidant, 0.1 to 5 parts of acid trapping agent and 0.1 to 2 parts of antiwear agent. The antioxidants, acid scavengers, and antiwear agents described above are all common in the art.
In one embodiment of the invention, the antioxidant is a phenolic antioxidant and/or an aminic antioxidant. Wherein the phenolic antioxidant is at least one selected from 2, 6-di-tert-butylphenol, 2, 6-di-tert-butyl-p-cresol (antioxidant 264) and 4, 4-methylenebis (2, 6-di-tert-butylphenol) (antioxidant 702); the amine antioxidant is at least one selected from dioctyl diphenylamine, dinonyl diphenylamine, octyl butyl diphenylamine, N-N' -di-sec-butyl p-phenylenediamine and N-phenyl-alpha-naphthylamine, and preferably dioctyl diphenylamine and/or N-phenyl-alpha-naphthylamine.
In one embodiment of the invention, the acid trapping agent is a compound having an epoxy ring or a carbodiimide compound, such as glycidyl dimethyloctanoate.
In one embodiment of the invention, the antiwear agent is selected from at least one of a phosphate, ammonium phosphate and phosphite, such as di-n-butyl phosphite, trimethylphenol phosphate, dialkyldithiophosphoric acid.
The refrigerating oil composition can be prepared by a conventional method, and comprises the steps of mixing base oil, a metal chelating agent and a dehydrating agent, and stirring at a constant temperature of less than or equal to-0.1 Mpa for 0.5-1 h to prevent air invasion to obtain the refrigerating oil composition. The base oil comprises naphthenic mineral oil, an antioxidant, an acid trapping agent and an antiwear agent.
Embodiments of the present invention also relate to the use of the refrigeration oil composition for internal lubrication of a compressor.
Embodiments of the present invention also relate to a compressor comprising the refrigeration oil composition provided by the present invention as a circulating liquid cooling system. The specific structure of the compressor is well known to those skilled in the art and will not be described in detail herein.
Examples
The refrigerating oil compositions 1 to 13 were obtained according to the production methods described in the embodiments, corresponding to examples 1 to 10 and comparative examples 1 to 3. The specific types of the components of the refrigerating oil composition and the added parts by weight are shown in Table 1.
Wherein the naphthenic mineral oil has a kinematic viscosity at 40 ℃ of 65mm2S, kinematic viscosity at 100 ℃ of 4mm2/s。
TABLE 1
Test example
The refrigerating oil compositions prepared in the above examples and comparative examples were subjected to a kinematic viscosity test (mm) at 40 ℃ using a capillary viscometer made of glass2S) to examine the viscosity-as-a-function of temperature performance of the refrigeration oil composition.
The refrigerating oil compositions prepared in the above examples and comparative examples were subjected to a stability test in accordance with experimental method for chemical stability of refrigerating machine oil in a refrigerant system (sealed glass tube method) of SH/T0698 to examine the oxidation resistance of the refrigerating oil compositions, and the unit of the acid value was mg KOH/g.
To the refrigerating oil compositions prepared in the above examples and comparative examples, a small amount of water was added to obtain an oil-water mixture so that the concentration of water in the oil-water mixture was 500ppm, in order to simulate the intrusion of water when the compressor was actually operated. The oil-water mixture is used for an accelerated life test of an R22 refrigerant compressor. And (3) testing parts in the compressor after performing a 500-hour accelerated life test under 1.88MPa, such as surface copper plating conditions of an inner circle of a cylinder, a roller, a slide sheet and the like, and calculating the copper plating rate. Wherein the copper plating rate is (copper plating area of the steel part/working area of the steel part) × 100%.
The results of the above tests are shown in Table 2.
TABLE 2
In each of the examples and comparative examples, the detailed selection of each component is not limited, and those skilled in the art can make the selection according to the summary of the invention. The test results were analyzed as follows:
as can be seen from the data in Table 2, the kinematic viscosity of the refrigerating oil composition is only related to the type and amount of the naphthenic mineral oil, and the kinematic viscosity is not affected by the addition amount and type of the additives.
As can be seen from examples 1 to 3, the addition of the metal chelating agent did not affect the acidity of the refrigerating oil composition. If the amount of the metal chelating agent added to the refrigerating oil composition is reduced, the copper plating rate is increased.
As can be seen from examples 1, 4 and 5, increasing the amount of the dehydrating agent added within a reasonable range, the acid value further decreased after the test due to the reaction of the dehydrating agent with water in the refrigerating oil composition, and the copper plating ratio remained 0. However, the quality content of other additives in the refrigerating oil composition is reduced by continuously increasing the addition amount of the dehydrating agent, and the performances of oxidation resistance, wear resistance and the like of the refrigerating oil composition are further influenced.
As can be seen from examples 1, 6 and 7, the acid number was unchanged after the test, replacing EDTA with tartaric acid or NTA. However, since the ability of the metal chelating agent to trap copper ions is lowered and the copper plating rate is increased, EDTA is preferred as the metal chelating agent in the present invention.
As can be seen from examples 1 and 8 to 10, when the acid trapping agent was removed from the refrigerating oil composition, the acid value and the copper plating ratio increased after the test. The antioxidant mainly affects the antioxidant properties of the refrigeration oil composition, and the anti-wear agent mainly protects the surfaces of parts from being worn during the operation of the compressor, so the test results in table 2 are not affected.
As can be seen from example 1 and comparative examples 1 to 3, if a metal chelating agent is not used, copper ions cannot be captured, and the copper plating rate is increased to 26%. If no dehydrating agent is used, the water in the refrigerating oil composition promotes the acidification reaction, the acid value is increased after the test, and the copper plating rate is increased to 31 percent. If the metal chelating agent and the dehydrating agent are not used, even if the acid trapping agent is added to the refrigerating oil composition, the copper plating rate is increased to 100%, that is, all the surfaces of all the steel parts are covered with the precipitated copper plating, and the parts are changed from silvery white to purplish red.
In combination with the above situation, the refrigerating oil composition provided by the invention can avoid the copper plating phenomenon in the operation process of the compressor, and improve the service life and the use safety of the compressor. And the added metal chelating agent and dehydrating agent do not affect other properties of the refrigerating oil composition.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
