Antibacterial ink for ceramic ink-jet printing and ceramic tile with antibacterial function

Abstract

The invention provides antibacterial ink for ceramic ink-jet printing and a ceramic tile with an antibacterial function. The antibacterial ink for the ceramic ink-jet printing comprises solvents and antibacterial agents which are uniformly dispersed in the solvents; the solvents are water solutions which are formed by 1, 2-propanediol and 1, 2-ethanediol; the antibacterial agents are formed by calcium phosphate and inorganic salt containing one or more antibacterial ions of silver, copper and zinc ions; the mass fraction of the calcium phosphate in the antibacterial agents is of 8 % to 20 % and the abundant is the soluble inorganic salt containing one or more antibacterial ions of silver, copper and zinc ions. The antibacterial ink can be used to printing the ceramic tile with the antibacterial function. Compared with the prior art, the antibacterial ink for the ceramic ink-jet printing has the advantages of enabling functions of the existing ink for the ceramic ink-jet printing to be enriched, enabling the ceramic pile which is produced by utilizing the antibacterial ink to have the antibacterial function, being high in whiteness, solving a color changing problem due to the fact that metal ions which are served as the antibacterial agents are restored or oxidized and being long in antibacterial effect.

Description

technical field [0001] The invention relates to an ink for ink-jet printing of ceramics, in particular to an ink for ink-jet printing of ceramics which can make ceramic tiles have an antibacterial function. Background technique [0002] Bacteria and mold, as pathogenic bacteria, are very harmful to humans, animals and plants, affecting people's health and even life-threatening, and bringing significant economic losses. Therefore, the research on antibacterial materials and their products has attracted people's attention day by day, and the demand for antibacterial products will constitute a huge market. Ceramic tiles have the characteristics of high strength, long service life, and rich decorative effects. They have always been the most commonly used building materials, and they are also one of the most frequently encountered materials. Therefore, if ceramic tile products can be made to have an antibacterial function, it will undoubtedly add a guarantee for human health. I...

Problems solved by technology

[0003] In addition, the antibacterial glaze with antibacterial ingredients is more expensive, and in order to ensure the quality of the glaze, the glaze layer is thicker, which greatly increases the production cost, and the use of metal ions as the antibacterial agent in the antibacterial glaze has a greater impact on the color. Affected, it is also easy to change color during use
