Problems solved by technology

However, adding inorganic antibacterial materials in this way will cause the inorganic antibacterial materials to react with the glaze layer material during the subsequent ceramic tile firing process to form a new phase, and the inorganic antibacterial materials will be wrapped by the glass phase formed by the glaze layer material , leading to the antibacterial ions in the inorganic antibacterial materials that can not smoothly overflow to the surface of the glaze layer, resulting in poor antibacterial effect and increased defects on the surface of the glaze layer.

Abstract

The invention discloses a production process of antibacterial ceramic bricks, which comprises the following process steps: 1) polishing the surface of fired glazed tiles to obtain polished semi-finished products; The dirty liquid is brushed and squeezed onto the glazed surface, the rotational speed of the grinding head is controlled at 50-70r / s, the pressure of the grinding head on the glazed surface is 30-60Pa, and the antibacterial ceramic tiles are obtained by waxing until the glossiness of the glazed surface is greater than 90 degrees. The finished product, the nano antibacterial antifouling liquid is prepared by mixing the tile antifouling liquid and nano antibacterial slurry according to the ratio of raw material parts by mass: 100:(5-30). The invention only adopts a simple, efficient and highly controllable production process to endow the glazed ceramic tiles with excellent antibacterial and antifouling properties, and the antibacterial ceramic tiles prepared by it have both high-efficiency, stable and durable antibacterial and antifouling properties, making the Antibacterial ceramic tiles can be mass-produced and widely used.

Description

Technical field [0001] The present invention relates to the field of ceramic tiles, in particular to a ceramic tile production process. Background [0002] With the rapid development of industry and the acceleration of the frequency of human activities, the pollution faced by human beings is becoming more and more serious, and the bacteria that breed therefrom also increase, bringing various diseases to human beings. As the most widely used decorative building material, ceramic tiles have the most frequent contact with humans. In particular, traditional glazed tiles, whose glazed pits and crevice structures under a magnifying glass provide a hiding and breeding place for bacteria, so how to give traditional polished tiles antibacterial and antifouling properties is particularly necessary. [0003] So far, the research direction of antibacterial ceramic tiles has been to prepare ceramic tiles with antibacterial properties by adding inorganic antibacterial materials to the glaze la...
