Preparation method for antibacterial glazed ceramic brick

Abstract

The invention discloses a preparation method for an antibacterial glazed ceramic brick. The preparation method comprises the following process steps: applying a ground glaze onto the surface of a green ceramic brick body, printing decorative patterns, applying a transparent glaze, then spraying an antibacterial mixed salt solution onto the surface of the transparent glaze so as to form an antibacterial layer, and carrying out high-temperature firing so as to obtain a finished product. According to the invention, a layer of the antibacterial mixed salt solution is sprayed onto the transparent glaze on the outermost surface of a glazed ceramic brick, so cost can be saved, and the antibacterial effect can be increased; and the glazed ceramic brick provided by the invention has the advantagesof good quality, low cost and significant antibacterial effect.

Description

technical field [0001] The invention relates to the field of architectural ceramics, in particular to an antibacterial ceramic brick. Background technique [0002] Glazed tiles are recognized by people because of their advantages of easy cleaning and rich decoration. Glazed antique tiles also occupy a large market. With the continuous improvement of people's living environment requirements, functional ceramic tiles have entered consumers. Field of view, especially antibacterial functional ceramic tiles. At present, antibacterial functional ceramics are mainly realized by adding antibacterial powder into the glaze, but the disadvantage of this method is that if the amount is too small, it will not be effective, and if the amount is too large, the cost will be high, and when the antibacterial powder is introduced by mixing , most of the antibacterial powder is in the glaze, and the antibacterial effect is only a layer of antibacterial powder on the outermost surface of the ce...

Problems solved by technology

At present, antibacterial functional ceramics are mainly realized by adding antibacterial powder into the glaze, but the disadvantage of this method is that if the amount is too small, it will not be effective, and if the amount is too large, it will cause high cost, and when the antibacterial powder is introduced by mixing , most of the antibacterial powder is in the glaze, and the antibacterial effect is only a layer of antibacterial powder on the outermost surface of the ceramic glaze, so this method not only wastes antibacterial powder, but also excessively mixed with antibacterial powder will also affect the quality of the product to a certain extent. Glaze quality

In addition, most of the antibacterial powders currently available in the field of high-temperature firing of ceramics are silver-loaded zirconium phosphate and silver-zinc loaded zirconium phosphate. These ingredients are on the outermost surface of the glaze, which can easily cause devitrification of the glaze surface.
