Embodiment 1

[0021] At room temperature, mix 600g of diamond and 600g of pure water evenly, then slowly add 200g of 10% polyvinyl alcohol 1788, stir and disperse evenly at a low speed, and then spray dry (inlet temperature 190°C, outlet temperature 110°C) to prepare spheres, Obtained spheres are aged at 400-600°C to obtain the spherical diamond accumulation abrasive, and the obtained results are shown in figure 1 .

[0022] Depend on figure 1 It can be seen that the obtained spherical diamond stacked abrasives are tightly bonded and have a good regular spherical shape.

Embodiment 2

[0024] At room temperature, mix 600g of diamonds with 600g of pure water evenly, then slowly add 10g of starch, stir and disperse evenly at a low speed, and then spray dry (inlet temperature 190°C, outlet temperature 110°C) to prepare spheres, and then aging at 400-600°C to obtain the spherical diamond stacked abrasive.

Embodiment 3

[0026] At room temperature, mix 600g of diamond with 600g of pure water evenly, then slowly add 10g of cellulose, stir and disperse evenly at a low speed, and then spray dry (inlet temperature 190°C, outlet temperature 110°C) to prepare spheres, and then obtain spheres aging at 400-600°C to obtain the spherical diamond stacked abrasive.

Abstract

The invention discloses a spherical diamond stacking abradant and a preparation method thereof. The spherical diamond stacking abradant is prepared from, by weight, 10-50% of diamond micro powder, 45-89% of pure water and 1-5% of bonding agent, wherein the grain diameter of the diamond micro powder is 1-100 micron, and the bonding agent is composed of starch, cellulose and polyvinyl alcohol. The spherical diamond stacking abradant has the advantages of having large cutting force, excellent self-sharpening performance, continuous grinding force and a better grinding effect, and can effectivelyprevent products from being scratched.

Description

technical field [0001] The invention belongs to the field of abrasive materials, in particular to a spherical diamond accumulation abrasive and a manufacturing method thereof. Background technique [0002] With the development of material science, the hardness of the materials used in the 3C technology field is getting higher and higher. The materials used in sapphire substrates, sapphire glass, ceramic mobile phone back covers, ceramic fingerprint identification chips and other products are all Mohs hardness 9. In the production process, it is often necessary to use abrasive tools to grind and polish the surface of these products. [0003] Abrasive is one of the main materials for making abrasive tools, and it is also one of the most important factors affecting the quality of abrasive tools. Ordinary abrasives have low hardness and are not suitable for grinding and polishing operations of products with high hardness. In some cases, special abrasives with large cutting forc...
