Problems solved by technology

[0004] The technical problem mainly solved by the present invention: the current microcrystalline tiles have stable chemical properties, acid and alkali resistance, corrosion resistance and weather resistance, but their surface gloss is very high, many features are similar to glass, and scratches are prone to occur. The back of the processed microcrystalline stone ceramic plate forms sawing grooves, which are easy to produce cracks in the paving process of construction, which causes a lot of waste of expensive microcrystalline stone resources, and provides a high hardness resistance The preparation method of scratched microcrystalline tiles, the method uses fish sauce and nickel nitrate as raw materials, adopts liquid phase reduction method to prepare ultrafine nickel powder, and then uses waste glass and fly ash to prepare microcrystalline glaze layer, supplemented by ultrafine The nickel powder is mixed and laid on the ordinary ceramic tile body, and the high hardness anti-scratch microcrystalline ceramic tile can be obtained through pressing and sintering. Greatly enhanced, it solves the defect that the surface of microcrystalline tiles is prone to scratches, and realizes waste utilization with waste glass and fly ash as raw materials. It is a green and environmentally friendly product with low cost.

Abstract

The invention relates to a preparation method of a high-hardness anti-scratch microcrystalline ceramic tile, belonging to the field of ceramic tile preparation. The method comprises the following steps: with fish paste and nickel nitrate as raw materials, preparing ultrafine nickel powder by a liquid-phase reduction process; preparing a microcrystalline glaze layer from waste glass and fly ash; mixing with the ultrafine nickel powder and paving on a common ceramic tile blank; and pressing and sintering to obtain the high-hardness anti-scratch microcrystalline ceramic tile. According to the microcrystalline ceramic tile prepared in the invention, since the ultrafine nickel powder is added into the microcrystalline glaze layer, the hardness is greatly enhanced, and the defect that scratches often occur on the surface of the microcrystalline ceramic tile is solved; moreover, by adopting the waste glass and fly ash as raw materials, waste utilization is realize, the cost is low, and the microcrystalline ceramic tile is an environment-friendly product.

Description

technical field [0001] The invention relates to a method for preparing high-hardness and scratch-resistant microcrystalline tiles, which belongs to the field of tile preparation. Background technique [0002] Microcrystalline tiles are called glass-ceramic composite panels in the industry. It is a high-tech product that combines a layer of 3-5mm glass-ceramic on the surface of ceramic vitrified fossils, and is completely integrated after secondary sintering. Simply put The biggest difference between microcrystalline stone and other ceramic tile products is that there is an extra layer of microcrystalline glass on the surface. In terms of appearance and texture, the surface finish of the polished plate is much higher than that of stone, and the glossiness can reach 90-120 gloss. The diffuse reflection of crystal particles can evenly distribute the light to any angle, making the board form a soft jade texture, which is more crystal and soft than natural stone, making the buil...
