Problems solved by technology

[0003] Hard and brittle materials have high hardness and high brittleness. Hard and brittle materials are widely used in daily life. However, their wide application is based on excellent surface smoothness and smoothness. Hard and brittle materials have superhard and Excellent anti-friction performance makes its surface treatment a difficult problem. Chemical mechanical polishing and grinding methods are commonly used to treat its surface. Abrasives are used to grind and polish the surface of the workpiece. The material removal rate is high, because of its high surface hardness, it is difficult to achieve the ideal surface roughness after processing

preparation example Construction

[0033] The invention provides a preparation method of catalytic abrasive particle mass, comprising the following steps:

[0034] Mixing the magnetic powder, catalyst, abrasive, adhesive and adhesive and pressing to obtain a blank, the catalyst includes metal oxide;

[0035] The blanks are sequentially dried and sintered to obtain the catalytic abrasive particle mass.

[0036] In the present invention, unless otherwise specified, the raw materials used are all commercially available products in the field.

[0037] In the present invention, the magnetic powder, the catalyst, the abrasive, the adhesive and the adhesive are mixed and then pressed to obtain a blank.

[0038] In the present invention, the abrasive, the magnetic powder and the catalyst are preferably mixed to obtain a mixture, and then mixed with the binder and the adhesive. The present invention does not have a special limitation on the mixing method. In a specific embodiment of the present invention, the mixing m...

Embodiment 1

[0065] In this embodiment, the particle size of the iron powder is 7-13 μm, and the particle size of the white corundum abrasive is 3.5-7 μm; the binder in this embodiment is silicon dioxide, potassium oxide, calcium oxide, boron oxide, and cobalt oxide by mass. The mixture obtained in a ratio of 1:1:1:1:1; the adhesive in this example is polyvinyl alcohol.

[0066] Mix the iron powder, iron oxide and white corundum abrasive with a mass ratio of 3:3:2 (i.e. iron powder 30g, iron oxide 30g, white corundum 20g) to obtain a mixture; then add a binder, the amount of It is 4% of the mass of the above-mentioned mixture, and then the adhesive is added, and the addition amount is 4% of the mass of the above-mentioned mixture, and the mixture is stirred to be fully mixed.

[0067] After mixing evenly, press it into a billet at a pressure of 75MPa, put it into a drying oven for drying treatment, the drying temperature is 110 °C, and the drying time is 8 h; then it is put into a muffle f...

Embodiment 2

[0069] The difference between this embodiment and the above-mentioned embodiment 1 is only that the ratios of iron powder, iron oxide and white corundum abrasive are different. In this embodiment, iron powder, iron oxide and white corundum abrasive are mixed in a mass ratio of 1:1:1. (ie iron powder 30g, iron oxide 30g, white corundum 30g).

Description

technical field [0001] The invention belongs to the field of abrasive materials, in particular to a catalytic abrasive particle mass and a preparation method thereof. Background technique [0002] Abrasives are widely used in industry and are known as industrial teeth, especially when manufacturing high-precision, low-roughness or high-hardness parts, abrasives are indispensable. With the rapid development of machinery manufacturing and structure Due to the adjustment of properties, the abrasive industry has higher and higher requirements for the quality of abrasives, forcing its continuous improvement and upgrading. [0003] Hard and brittle materials have high hardness and high brittleness. Hard and brittle materials are widely used in daily life. However, their wide application is based on excellent surface flatness and smoothness, while hard and brittle materials have superhard and brittle materials. The outstanding anti-friction performance makes its surface treatment ...
