Embodiment Construction

[0018] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0019] A sapphire diamond liquid, comprising 0.5-1.0 parts of polycrystalline diamond powder, 0.5-1.0 parts of dispersant, 0.1-0.5 parts of water-based thickener, 2-4 parts of alkaline regulator, 3-5 parts of penetrating agent, 1 -2 parts of vapor phase anti-settling agent, 86.5-92 parts of base solvent;

[0020] The base solvent is prepared by mixing one or more of deionized water, ethylene glycol, and glycerin.

[0021] Preparation method: 1. Make the base solvent: put the base solvent into the reaction kettle and stir at 600 rpm for 10 minutes, 2. Add dispersant, penetrant, gas phase anti-sedimentation agent, water-based thickener, and alkaline regulator in sequence , adding interval time is 5-10min, 3. Add polycrystalline diamond powder and stir for 90min, after filling, ultrasonic for 45min; you can get sapph...

Abstract

The invention provides sapphire drilling liquid. The sapphire drilling liquid comprises 0.5-1.0 part of polycrystalline diamond powder, 0.5-1.0 part of dispersing agents, 0.1-0.5 part of water-based thickener, 2-4 parts of alkaline regulator, 3-5 parts of penetrant, 1-2 parts of gas phase anti-settling agents and 86.5-92 parts of basic solvent. The basic solvent is prepared by mixing one or more of deionized water, ethylene glycol and glycerin. The polycrystalline diamond powder is adopted as a grinding material, and is moistened through the penetrant, the even, stable, stably suspended and agglomeration-free effect is kept in an aqueous system of the sapphire drilling liquid, and the effect of improving cutting efficiency is achieved in the use process.

Description

technical field [0001] The invention relates to the technical field of diamond liquid grinding, in particular to a sapphire diamond liquid. Background technique [0002] With the deepening of research and application of sapphire, the application of sapphire touch screen is more and more extensive, such as high-end watches, high-end mobile phone screens, aerospace special glass, etc. [0003] In the sapphire touch screen processing industry, A-direction sapphire is more difficult to process than ordinary sapphire. Generally, the processing time of diamond liquid is long, the cutting rate is low, and the loss of grinding disc is large, which increases the cost of robot labor. [0004] Chinese patent CN200710177815.7 discloses a water-based diamond grinding liquid and its preparation method and application. The components are: diamond micropowder 0.01-10%, dispersion stabilizer 0.5-15%, suspending agent 0.1-10%, pH regulator 0.0-1.0%, preservative 0.0-1%, organic solvent 0.0-9...
