Definitions
- Fluorinated hydrocarbon compounds method for producing the same, refrigeration oil and lubricating oil for magnetic recording media
- the present invention relates to a novel compound which can be generally used as a lubricating oil and a method for producing the same, and more particularly, to an oxygen atom or a sulfur atom in a molecule useful as a refrigerating machine oil or a lubricating oil for a magnetic recording medium.
- the present invention relates to a fluorinated hydrocarbon compound containing atoms and a method for producing the same.
- the present invention relates to uses of the fluorinated hydrocarbon compound, and more particularly to a refrigerating machine oil and a lubricating oil for a magnetic recording medium.
- the refrigerator according to the present invention also includes a heat pump.
- Hydrogen-containing fluorinated hydrocarbons such as CH 2 FCF 3 (fluoro 13 14 a) have been proposed as refrigerants replacing fluoro 11 and fluoro 11. This does not destroy the ozone layer, but has very low compatibility with conventional refrigeration oils. Therefore, if conventional refrigerating machine oil is applied to a refrigerating machine that uses hydrogen-containing hydrofluoric hydrocarbons as a refrigerant, the durability of the compressor will decrease and the compressor will not be able to operate in a short time, or the cooling capacity and performance of the refrigerator will be reduced. Coefficients drop significantly.
- fluorine-containing oil which is a compound considered to have good compatibility with hydrogen-containing fluorine-containing hydrocarbons, as the refrigerating machine oil.
- fluorine-based oil which is a compound considered to have good compatibility with hydrogen-containing fluorine-containing hydrocarbons, as the refrigerating machine oil.

- each of the main structures has the following repeating units.
- n and m are an integer of 1 or more.
- these known fluorine-based oils are not necessarily satisfactory in terms of compatibility with the refrigerant. It is considered that these fluorine-based oils have little or no hydrogen in their structures. In addition, these fluorine-based oils are difficult to put into practical use because the monomer corresponding to the repeating unit in the structure is expensive. Therefore, when the above-mentioned hydrogen-containing fluorine-containing hydrocarbon is used as a refrigerant, in order to improve the compatibility between the refrigerant and the refrigerating machine oil, the fluorine-containing fluorine is used together with the fluorine.
- a lubricant is mixed into the magnetic layer or a method such as bibbing or spin coating is applied to the thin magnetic layer in order to improve running stability and durability.
- a fluorine-containing polyether described in Japanese Patent Application Laid-Open No. 61-113130 is known. Have been.
- the above-mentioned fluorine-containing polyether is not sufficiently dispersed in a general-purpose hydrocarbon-based organic solvent at the time of forming a coating material. Therefore, since the lubricant is dissipated from the magnetic layer due to sliding of the magnetic recording medium and the magnetic head after the application, the abrasion resistance and durability of the magnetic recording medium are not satisfactory.
- Solvents that sufficiently dissolve fluorine-containing polyethers include fluorine-based solvents, but general-purpose solvents such as trichloro-trifluoroethane are likely to deplete the ozone layer in recent years. Fluorine-based solvents (for example, C 6 F 1; 1 ), which cannot be used and do not destroy the ozone layer, are also expensive, although they dissolve conventional fluorine-containing polyethers. It has also been reported to be involved in global warming, and its use requires caution.
