Embodiment 1

[0048] A preparation method for a vitrified bond for a ceramic grinding block, comprising the steps of:

[0049] a. Compounding raw materials: weigh each raw material according to the following weight unit (in kilograms), SiO 2 45Kg, Al 2 o 3 17 Kg, ZnO 1 Kg, TiO 2 1 Kg, ZrO 2 Kg, Na 2 CO 3 12 Kg, Li 2 CO 3 9 Kg, H 3 BO 3 13 Kg, dropped into the mixer and mixed for 2 hours;

[0050] b. Powder smelting: Pour the uniformly mixed raw materials into a glass melting furnace for melting, the melting temperature is 1350°C, and the melting time is 1.5 hours, and the uniformly mixed raw materials are smelted into molten glass;

[0051] c. Solution quenching: the smelted glass liquid is quickly poured into cold water for rapid cooling to form a coarse material, wherein the temperature of the cold water is 20°C, and the cooling time is 30s;

[0052] d. Coarse material crushing: Pour the coarse material obtained in step c into a crusher for crushing, and pass through a...

Abstract

The invention discloses a ceramic binding agent for a ceramic grinding block and a preparation method thereof and belongs to the technical field of powder metallurgy materials. The ceramic binding agent aims at achieving the effects that the retention to diamond is good, the expansion coefficient is matched with expansion coefficients of silicon carbide, brown aluminum oxide and the diamond, and the sintering temperature of a finished product is low. The ceramic binding agent is formed by the following powder materials of, by weight, 20 to 55 kilograms of silicon dioxide, 5 to 25 kilograms of aluminum oxide, 0 to 5 kilograms of zinc oxide, 0 to 5 kilograms of titanium dioxide, 0 to 7 kilograms of zirconium oxide, 10 to 20 kilograms of sodium carbonate, 5 to 15 kilograms of lithium carbonate and 8 to 30 kilograms of boric acid. According to the ceramic binding agent for the ceramic grinding block, the ceramic grinding block has the advantages of being low in sintering temperature, good in self-sharpening, good in sharpness, long in service life, low in carbon and environmentally friendly.

Description

technical field [0001] The invention relates to a bonding agent for grinding blocks and a preparation method, in particular to a bonding agent and a preparation method for ceramic grinding blocks used in the fine grinding process of wall and floor tile processing, and belongs to the technical field of powder metallurgy materials. Background technique [0002] The ceramic tile production line is the main equipment in the wall and floor tile industry. At present, there are about 3,000 ceramic production lines in the country, of which there are more than 2,000 polishing lines, and the annual consumption of grinding blocks is very large. There are three types of grinding blocks used in tile polishing line: metal grinding blocks, silicon carbide grinding blocks and magnesite grinding blocks, which are used for coarse grinding, medium fine grinding and polishing respectively. Among them, silicon carbide grinding blocks are used in the largest amount for medium and fine grinding, b...
