preparation example Construction

[0043] see figure 1 , the preparation method of the diamond grinding paste of an embodiment, comprises the following steps:

[0044] S110, ultrasonically mixing the diamond micropowder, the liquid oil and the dispersant to obtain a diamond slurry.

[0045] In one embodiment, the ultrasonic frequency during the ultrasonic mixing treatment is 20 kHz to 60 kHz.

[0046] In one embodiment, the diamond micropowder, the liquid oil and the dispersant are ultrasonically mixed and treated while being stirred, and the stirring speed is 500rad / min-800rad / min.

[0047] In one embodiment, the ultrasonic mixing treatment of the diamond micropowder, the liquid oil and the dispersant is 10 minutes to 30 minutes.

[0048] S120, uniformly mixing the surfactant and the lithium-based lubricant to obtain a mixture.

[0049] In one of the embodiments, the surfactant and the lithium-based lubricant are stirred until uniformly mixed. The rotating speed of stirring treatment is 500rad / min-800rad / m...

Embodiment 1

[0055] 5 parts of diamond micropowder, 20 parts of peanut oil and 10 parts of glycerin were mixed uniformly under ultrasonic stirring to obtain diamond slurry. The ultrasonic frequency is 60 kHz, the stirring rate is 500 rad / min, and the mixing time is 10 min. Among them, the particle size of the diamond micropowder is 7 μm.

[0056]15 parts of polyoxyethylene oleate and 50 parts of lithium-based lubricant were uniformly mixed, the stirring rate during mixing was 500 rad / min, and the mixing time was 15 min. Wherein, the lithium-based lubricant is prepared from 7.5 parts of animal and vegetable oils, 15 parts of lithium hydroxide, 20 parts of fatty acids and 7.5 parts of base oil.

[0057] The mixture of the above-mentioned surfactant and the lithium-based lubricant was added to the above-mentioned diamond slurry and mixed uniformly to obtain a diamond grinding paste. The stirring rate during mixing was 600 rad / min, and the mixing time was 15 min.

Embodiment 2

[0059] 8 parts of diamond micropowder, 15 parts of rapeseed oil and 15 parts of triethanolamine were mixed uniformly under ultrasonic stirring to obtain diamond slurry. The ultrasonic frequency is 40 kHz, the stirring rate is 600 rad / min, and the mixing time is 25 min. Among them, the particle size of the diamond micropowder is 5 μm.

[0060] 12 parts of polyoxyethylene stearate and 45 parts of lithium-based lubricant were uniformly mixed, the stirring rate during mixing was 600 rad / min, and the mixing time was 15 min. Wherein, the lithium-based lubricant is prepared from 6.75 parts of animal and vegetable oils, 13.5 parts of lithium hydroxide, 18 parts of fatty acids and 6.75 parts of base oil.

[0061] The mixture of the above-mentioned surfactant and lithium-based lubricant was added to the above-mentioned diamond slurry and mixed uniformly to obtain a diamond grinding paste. The stirring rate during mixing was 600 rad / min, and the mixing time was 10 min.

Abstract

The invention relates to a diamond grinding paste and a preparation method thereof. The diamond grinding paste is characterized by comprising the components in parts by mass: 5-20 parts of diamond micropowder, 10-25 parts of dispersant, 10-15 parts of surfactant, 15-20 parts of liquid oil and 40-50 parts of lithium-based lubricant, wherein the surfactant is a nonionic surfactant; the lithium-basedlubricant comprises the components in parts by mass: 6-7.5 parts of animal and plant oil, 12-15 parts of lithium hydroxide, 16-18 parts of fatty acid and 6-7.5 parts of base oil. The diamond grindingpaste prepared by reasonably proportioning the diamond micropowder, the dispersant, the nonionic surfactant, the liquid oil and the lithium-based lubricant has the consistency grade of 0-3 # and hasrelatively good flowability, and the diamond micropowder has good dispersibility in the diamond grinding paste and generates few scratches when grinding a high-hardness material.

Description

technical field [0001] The invention relates to the technical field of grinding paste preparation, in particular to diamond grinding paste and a preparation method thereof. Background technique [0002] Diamond micropowder is an ultrafine abrasive with good mechanical and physical properties such as high strength and corrosion resistance. At present, diamond powder is widely used in the processing of high-hardness materials such as ceramics, sapphire, cemented carbide, and silicon wafers. According to the processing purposes in different fields, diamond powder can be prepared into aerosol, oily or watery liquid, paste and other products. At present, the industry mainly focuses on the research on diamond aerosol and diamond abrasive liquid, while the research on diamond abrasive paste is still relatively limited. At present, diamond abrasive pastes still have problems such as poor abrasive dispersion, low fluidity, and easy scratches. Contents of the invention [0003] B...
