Nano seamless antifouling ceramic tile and preparation method thereof

Abstract

The invention discloses a nano seamless antifouling ceramic tile and a preparation method thereof. The nano seamless antifouling ceramic tile comprises a blank body and a surface glaze, wherein the blank body is prepared from the following raw materials in parts by weight: modified clay, potassium feldspar powder, albite powder, quartz powder, a binder, talcum powder, carbon fibers, fused corundumpowder and a dispersing agent; and the surface glaze is prepared from the following raw materials in parts by weight: potassium feldspar, albite, kaolin, dolomite, wollastonite, zinc oxide, barium carbonate, matte frit, white corundum and ground calcium carbonate. The invention also provides a preparation method of a high-strength antifouling ceramic tile. The preparation method comprises the following steps: preparing the blank body, coating the blank body with the surface glaze and firing. The quantity of open pores in the surface of the blank body is reduced, and the dirt adsorption capacity is reduced, so that the antifouling capacity is improved. The quantity of the open pores in the surface of the polished blank is reduced, and the dirt adsorption capacity is reduced, so that the antifouling capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of ceramic tiles, and in particular relates to a nano seamless antifouling ceramic tile and a preparation method thereof. Background technique [0002] With the rapid development of the current real estate industry, the production and consumption of ceramic tiles have achieved great development. Existing ceramic tiles generally have the defect of weak anti-fouling performance. There are two main reasons for the poor anti-fouling performance. The first is that there are pores inside the ceramic tiles. Test analysis found that most of the ceramic tiles only eliminated the surface during the sintering process. There are still 4%-5% closed pores in the porcelain blank. When the surface of the tile is polished, these closed pores are exposed on the surface of the tile to form open pores, which reduces the antifouling property of the surface of the polished tile. The gas in the brick body mainly comes from the g...

Second, microcracks are formed on the surface of the ceramic tile. Since the thermal expansion coefficients of the fine quartz particles in the ceramic tile body and the newly produced glass phase are very different, when the content of granular quartz in the body is too much or the cooling system during firing is unreasonable, cooling When the glass phase is subjected to a large tensile stress, it will cause microcracks. When the product is subjected to three force-bearing processes of rough grinding, fine grinding and polishing in the later stage, the microcracks in the ceramic tile body will expand to varying degrees, and the microcracks will expand to varying degrees. The expansion of the product caused a significant decrease in the antifouling properties of the product

[0004] The existing ceramic tiles also have the defect of poor flexural strength. During transportation, even on the wall that has been attached, cracks will appear when a little external force is applied. This is due to the insufficient viscosity of the materials used to prepare ceramic tiles. caused by
