Embodiment 1

[0044]Example 1: Take 1.5 grams of single crystal diamond powder with a particle size distribution of 2-4 μm and D50 of 2.95 μm ± 5%, 8 grams of sodium dodecylsulfonate, 15 grams of polyethylene glycol, and stir for 30 minutes with a magnetic stirrer , Ultrasonic ultrasonic dispersion for 30 minutes, mixed into a diamond solution. Disperse and mix 2 grams of polyacrylic acid, 10 grams of ethylene glycol and 62.5 grams of purified water evenly, stir with a magnetic stirrer for 30 minutes, and ultrasonically disperse for 30 minutes, and mix to form a suspending agent solution. Stir the diamond solution and the suspending agent solution with a magnetic stirrer for 30 minutes and mix them evenly, and then disperse them with ultrasonic waves for 30 minutes. After homogenizing the mixed solution, add 1 gram of 1% sodium bicarbonate solution, adjust the pH range between 6-7, and stir with a high-speed mixer for 10 minutes to obtain a hydrophilic diamond suspension grinding and polish...

Abstract

The invention discloses a hydrophilic diamond-suspended grinding and polishing solution and a preparation method thereof. The hydrophilic diamond-suspended grinding and polishing solution comprises the following raw materials in percentage by weight: 0.05-15% of diamond powder, 0.005-15% of suspending agent, 0.005-12% of surfactant, 0.05-60% of friction modifier, 0.0005-5% of pH value regulator and the balance of dispersion medium. The hydrophilic diamond-suspended grinding and polishing solution provided by the invention can keep a stable and uniform state for a long time and can not cause precipitation, sedimentation and inactivation phenomena; and the suspending medium plays a role of a suspending carrier and also has the effects of cooling, lubrication and chip removal in the grinding and polishing process.

Description

technical field [0001] The invention relates to a diamond suspension grinding and polishing liquid and a preparation method thereof, in particular to a hydrophilic diamond suspension grinding and polishing liquid and a preparation method thereof. Background technique [0002] High efficiency, high precision and automation are the goals pursued by modern grinding technology. With the continuous emergence of high-tech products, the machining accuracy and surface integrity are getting higher and higher, and traditional grinding is developing in the direction of ultra-precision grinding, ultra-precision grinding and polishing.
