Example Embodiment

[0026] Example 1

[0027] A water-oil two-soluble diamond grinding fluid, prepared from the following weight percentages of raw materials: C16 isoparaffin 86.2%, stearic acid polyoxyethylene ether (5-10EO) 5%, oleic acid polyoxyethylene ether (2EO) ) 5%, 0.3% 2,6-di-tert-butyl mixed phenol, 1.5% 0.5μm single crystal diamond powder, and the balance is water.

[0028] (1) Mix the base oil, emulsifier, co-emulsifier and oil anti-aging agent evenly, then pour it into the reactor, heat the reactor, and heat for 10 min under stirring conditions at 70°C;

[0029] (2) Add the diamond abrasive to the water, place it in the ultrasonic wave and stir for 10 minutes to make the diamond abrasive evenly dispersed and take out the mixed solution;

[0030] (3) Slowly add the mixed liquid dispersed with diamond abrasives into the reaction kettle, heat at 70°C for 30 minutes under stirring conditions, and then drop to room temperature under stirring conditions to obtain water-oil two-soluble diamond slu...

Abstract

The invention discloses water-soluble and oil-soluble diamond grinding liquid, and belongs to the field of precise finishing and polishing processing. The liquid is prepared by the following raw materials in percentages by weight: 54-87% of base oil, 5-15% of an emulsifier, 5-10% of a co-emulsifier, 0.1-1% of an anti-aging agent of oil products, 0.05-5% of a diamond abrasive, and the balance being water. The invention also discloses a preparation method of the water-soluble and oil-soluble diamond grinding liquid, and the method comprises the following steps: (1) the base oil, the emulsifier, the co-emulsifier and the anti-aging agent of oil products are mixed and poured into a reaction vessel, and heating is carried out with stirring at 70 DEG C for 10-20 minutes; (2) the diamond abrasive is added into water and placed in supersonic wave with stirring for 10 minutes, and mixed liquor is obtained; (3) the mixed liquor with dispersed diamond abrasive is slowly added into a reaction vessel, temperature is raised to 70 DEG C with stirring for 30 minutes, temperature is reduced to room temperature with stirring, and the water-soluble and oil-soluble diamond grinding liquid is obtained.

Description

technical field [0001] The invention belongs to the field of precision grinding and polishing processing, and in particular relates to a water-oil two-soluble diamond grinding fluid and a preparation method thereof. Background technique [0002] As the third-generation semiconductor material GaN after Si and GaAs, its application in devices is regarded as the most important event in semiconductors in the 1990s, which brought semiconductor light-emitting diodes and lasers to a new level. However, in In practical applications, GaN materials are difficult to produce, and thin films must be grown on other substrate materials. At present, there are many substrate materials for growing GaN materials, including sapphire, silicon carbide, silicon, magnesium oxide, etc., and sapphire is the most The main substrate material. [0003] The sapphire screen is artificially synthesized sapphire glass. Compared with the traditional glass display screen, the sapphire screen is harder and mo...
