Description
Technical Field
The invention belongs to the technical field of high molecular compound compositions and refrigerating machine oil products, relates to refrigerating machine oil base oil and a preparation method thereof, and a mixed composition for a refrigerator, and particularly relates to refrigerating machine oil base oil suitable for an HFO mixed refrigerant, a preparation method thereof and a mixed composition for a refrigerator.
Background
In 2021, 9 and 15, the "ken cali amendment" of the "montreal protocol" formally takes effect in China, and according to the requirements of the "ken cali amendment" of the "montreal protocol", china needs to freeze the production and use of hydrofluorocarbon refrigerants (HFCs) at the baseline level in 2024, and to cut down by 10%, 30%, 50% and 80% in 2029, 2035, 2040 and 2045, respectively. The listed hydrofluorocarbon refrigerants needing to be cut include a plurality of substances with high GWP values such as R134a, and the refrigerants used in the Chinese automobile air-conditioner are mainly R134a so far.
The HFO refrigerant is expected to replace R134a to be applied to the field of automobile air conditioning, and the refrigerator oil is in a working environment with low temperature and high pressure in the compressor for a long time, so that the oxidation resistance and chemical stability of the refrigerator oil are very important for ensuring the long-term reliable operation of the compressor. Therefore, for the novel HFO mixed refrigerant, development of a matched refrigerator oil having good compatibility, excellent oxidation resistance and chemical stability is required.
Patent application WO2018/190354 discloses a refrigerator oil suitable for mixed refrigerants having HFO contents of no more than 40%, consisting of polyvinyl ethers (PVEs) or/and polyol esters (POE). HFO-based refrigerants, however, decompose to produce trifluoroacetic acid (TFA), resulting in an increase in acid number, which increases the likelihood of corrosion of metal parts, accelerated seal aging, and also results in degradation of refrigerator oils, particularly POE oils. The conventional POE oil (also called common base oil) is produced by taking medium-long chain fatty acid (such as C8 and C9 acid) as a raw material and reacting with polyol (such as pentaerythritol, dipentaerythritol and the like), the problem of incomplete polyol reaction exists, and the decomposition of HFO can be accelerated by hydroxyl which does not participate in the reaction. Patent application WO2022/209688 discloses the addition of epoxides to common base oils to inhibit the increase in acid number, but the addition of epoxides may result in a decrease in the oxidative and chemical stability of the refrigerator oil.

1. Analysis of physicochemical Properties
The POE base oils obtained in examples 1 to 3 and comparative examples 1 to 4 were measured for color, density at 25 ℃, viscosity at 40 ℃, flash point, pour point, and hydroxyl value, and the results are shown in Table 1 below.
TABLE 1 physicochemical Properties
As can be seen from table 1, the hydroxyl value of the refrigerator oil base oil obtained in the examples is significantly smaller than that of comparative example 1, thus demonstrating that the hydroxyl value of the POE base oil can be significantly reduced without affecting other important physicochemical properties by adding short-chain fatty acids to the POE oil to react with the remaining unreacted polyol.
Comparative example 3 has a relatively high hydroxyl value of the POE base oil obtained due to the presence of incompletely esterified pentaerythritol, resulting in poor chemical stability in the refrigerant, and the possibility of reacting with HFO refrigerant, accelerating the decomposition of HFO, and thus promoting the formation of TFA (trifluoroacetic acid).
Comparative example 4 the POE base oil obtained by adding short chain fatty mono-acids with 50% total fatty acid content to long chain fatty acids has a lower flash point and a pour point higher than-30 ℃ resulting in a poorer chemical stability in the refrigerant than the examples, and the POE base oil has an acid value and a fluorine content higher than the examples of the present invention, thus being corrosive to metals, and the two-phase separation temperature of the POE base oil and the refrigerant is about 10 ℃ worse than the examples.
2. Compatibility test of refrigerant mixture with HFO at different oil contents
The POE base oils obtained in the examples and comparative examples were mixed with HFO mixed refrigerant, and the compatibility of POE base oil and HFO mixed refrigerant at different oil contents was measured, and the results are shown in tables 2 and 3 below.
The HFO refrigerant blend in this example consisted of, by weight, R1132 (E) 28%, R1234yf 50.5% and R32.5%.
From tables 2 and 3, the refrigerating machine oil base oil and the HFO mixed refrigerant with different contents are compatible at-50 ℃ to 40 ℃, which shows that the refrigerant provided by the invention is completely matched with the HFO mixed refrigerant in use performance, and can meet various use scenes of the refrigerant.
TABLE 2 results of Low temperature (-70 ℃ C. To 20 ℃ C.) compatibility tests (°C.)
TABLE 3 results of high temperature (20 ℃ -60 ℃) compatibility tests (°C)
3. Chemical stability test
The refrigerator oil base oils of examples 1-3 and comparative examples 1-4 were heated with HFO mixed refrigerant at 175℃for 14 days, and subjected to chemical stability test. The results are shown in Table 4.
The HFO refrigerant blend in this example consisted of, by weight, R1132 (E) 28%, R1234yf 50.5% and R32.5%.
Table 4 chemical stability test
As is clear from Table 4, the refrigerator oil base oils of examples 1 and 2 were unchanged in chromaticity and lower in acid value and fluorine content than those of comparative examples 1 and 2 after 14 days of chemical stability test, thereby demonstrating that the present invention can effectively alleviate fluorine-containing acidic substances such as TFA generated by decomposition of HFO and metal corrosion by adding short-chain fatty monoacid esters to the refrigerator oil base oils.
In summary, the present invention can slow down the decomposition of HFO components in HFO mixed refrigerants to produce TFA by adding short chain fatty mono-acid esters to the refrigerator oil base oil. And the physical and chemical properties of POE base oil added with short-chain fatty monoacid ester still meet the relevant national standard, and the low-temperature compatibility and the high-temperature compatibility of the POE base oil with HFO mixed refrigerant are excellent, and the POE base oil can be compatible with the HFO mixed refrigerant at the oil content of 5% -60% at the temperature of-50 ℃ to 40 ℃.
