Problems solved by technology

[0003] With the improvement of people's living standards, antibacterial tiles have gradually become an emerging technology and have been widely concerned: this type of function is required in indoor environments, especially in hospitals, schools and shopping malls with large traffic and closed spaces. Higher, by adding a photocatalyst to the glaze, the tiles will have a sterilizing effect under ultraviolet light, but the antibacterial effect in natural light or indoor lighting environment is not yet able to achieve the desired effect. Metal ions are directly added to the glaze or carried by a carrier. The antibacterial ceramic tiles obtained after firing mainly use silver, copper and zinc plasma to achieve the bactericidal effect, but these ions are easy to volatilize when fired at high temperature. Not resistant to high temperature, which greatly reduces the antibacterial performance of ceramic tiles; in some technologies, rare earth elements are added to the glaze to activate the antibacterial performance of nanocomposite high temperature resistant materials. Specifically, layered clay is used to adsorb strontium ions and rare earth ions to Between the clay crystal layers, the antibacterial effect activated by rare earth ions is realized, which successfully improves the heat resistance of the antibacterial particles; but this technology using clay reduces the wear resistance of the glaze layer, making the tiles durable in long-term use. In the end, not only the glaze layer is worn and the pattern is incomplete, which affects the appearance, but also because the antibacterial agent can only work on the surface of the glaze layer, and the thickness of the glaze layer will cause waste of antibacterial agent, so the thin layer is not wear-resistant. The glaze layer, resulting in a very short time for the tile to really have antibacterial effect; the antibacterial effect of the tile is also consumed with the wear of the glaze layer
The addition of conventional anti-wear materials returns to the dense structure of the glaze layer, resulting in the antibacterial particles being completely sealed and unable to contact with bacteria, and the antibacterial effect cannot be displayed

Abstract

The invention provides a manufacturing method of antibacterial ceramic tiles, and belongs to the technical field of architectural ceramics. The manufacturing method of the antibacterial ceramic tiles is characterized by comprising the following steps: printing protective glaze after inkjet printing, wherein the protective glaze comprises the following raw materials in parts by weight: 11-13 parts of Qidao clay, 11-13 parts of calcium carbonate, 4.5-5.5 parts of barium carbonate, 4.5-5.5 parts of burnt bone stone, 28.5-32.5 parts of potassium feldspar, 14-16 parts of glaze frits, 1.7-2.3 parts of zirconium silicate, 15-18 parts of albite, 1.7-2.3 parts of zinc oxide and 7-9 parts of an antibacterial agent; and in the firing step, increasing the temperature of a kiln to 835-840 DEG C, insulating for 1.5-2.5 hours, then heating to the temperature of 1,200-1,210 DEG C, insulating for 3-4 hours, and then cooling. The protective glaze is suitable for the antibacterial agent to efficiently play effects for a long time, and by a ceramic tile firing mode for the glaze, the wear-resistant and long-acting antibacterial ceramic tile can be obtained.
