Preparation method of antibacterial ceramic
The invention discloses a preparation method of an antibacterial ceramic. According to the method, a glaze formulation and a glazing method are optimized and improved, so that the durable ceramic with a high antibacterial property can be obtained by a conventional universal ceramic production method under the conventional universal preparation conditions. The method has the outstanding characteristics that antibacterial ions are attached to a white carbon black carrier by a sol-gel method so as to obtain an antibacterial powder material, the antibacterial powder material is mixed with a common glaze material and the mixture is subjected to wet ball milling to prepare composite antibacterial glaze slip; then by adopting a double-layer glazing method, a common glaze material inner layer is uniformly poured and a composite antibacterial glaze slip outer layer is uniformly sprayed on the outer wall of a green body or a biscuit; finally, the obtained product is baked at a high temperature to form the required antibacterial ceramic. The method has the advantages that not only the product has the antibacterial broad-spectrum property and a high sterilizing rate, has no drug resistance and is environmental-friendly and healthy, but also the antibacterial metal ions are lost a little in the baking process, and have a high ion activity and a high usage rate; the antibacterial glaze material has good adsorbability and influences a ceramic green body a little; the ceramic is integrally high in quality and has strong damage resistance; moreover, a glaze surface is smooth and wear-resistant. Generally, the antibacterial ceramic prepared by the preparation method is controllable in cost, has high cost performance and is beneficial to scale quantitative production in the future market.
