example 1

[0110] [Example 1] Manufacture of CFO-1214ya

[0111] The method of Example 1 of International Publication No. 2010 / 074254 was repeatedly implemented to obtain a total of 3900 g of 1,1-dichloro-2,3,3,3-tetrafluoro-1-propene (CFO-1214ya).

[0112] Specifically, 3 g of tetrabutylammonium bromide, 83 g (1.485 moles) of potassium hydroxide, and 180 g of water were added as a phase transfer catalyst to a glass reactor with an inner volume of 1 L equipped with a serpentine condenser cooled to 0° C. , 609g (3 moles) of the product name "ASAHIKLIN AK225" (Asahi Glass Co., Ltd. (Asahi Glass Co., Ltd.), a mixture of HCFC-225ca of 48 mole % and HCFC-225cb of 52 mole %), slowly heated up while stirring, React at 45°C for 1 hour. After the reaction, the organic phase was separated from the crude reaction liquid separated into two phases of an organic phase and an aqueous phase, and the organic phase was distilled in a distillation column with a tank volume of 1 L and a capacity of 10 theo...

example 2

[0115]The solvent formed from CFO-1214ya obtained in Example 1 was mixed with the product name "Krytox (registered trademark) GPL102" (manufactured by DuPont, fluorine oil) as a fluorine-based lubricant to make the content of the fluorine-based lubricant 0.5 Mass % lubricant solution.

[0116] Next, the obtained lubricant solution was applied to the surface of an aluminum vapor-deposited plate obtained by vapor-depositing aluminum on an iron plate with an average thickness of about 0.4 mm, and air-dried at 19 to 21° C. A lubricant coating film is formed on the board surface.

example 3～34

[0118] Lubricant solutions were produced in the same manner as in Example 2 except that the composition of the solvent was changed as shown in Table 1. Then, a lubricant coating film was formed in the same manner as in Example 2.

Abstract

The purpose of the present invention is to provide: a lubricant solution which does not adversely impact the global environment, has excellent lubricant solubility, and is able to form a uniform lubricant coating that has satisfactory drying properties; and a method for producing an article provided with a lubricant coating in which the lubricant solution is used. A lubricant solution, wherein the solvent comprises 1,1-dichloro-2,3,3,3-tetrafluoro-1-propene. Also, a method for producing an article provided with a lubricant coating, the method being characterized by comprising coating an article to be coated with the lubricant solution, evaporating the solvent, and forming a lubricant coating on the article to be coated.

Description

technical field [0001] The present invention relates to a lubricant solution and a method for producing lubricant-coated articles. Background technique [0002] As a method for producing articles having coating films containing various organic chemical substances such as lubricants, it is known, for example, to prepare a solution in which the organic chemical substance is dissolved in a diluting solvent, apply the solution to an object to be coated, and dilute A method of forming a coating film by evaporating a solvent. The solvent used for dilution is required to fully dissolve the organic chemical substance and have sufficient drying properties. [0003] Conventionally, fluorine-based solvents such as 1,1,2-trichloro-1,2,2-trifluoroethane, etc. Hydrocarbons (hereinafter referred to as "CFCs"), 2,2-dichloro-1,1,1-trifluoroethane, 1,1-dichloro-1-fluoroethane, 3,3-dichloro- 1,1,1,2,2-pentafluoropropane, 1,3-dichloro-1,1,2,2,3-pentafluoropropane and other hydrochlorofluoroc...
