Abstract

The invention belongs to the technical field of domestic ceramics, and particularly relates to a high-strength antibacterial domestic ceramic and a preparation method thereof. The high-strength antibacterial domestic ceramic comprises a domestic ceramic green body and a glaze layer, wherein the glaze layer is prepared from the following raw materials in parts by weight: 40-50 parts of baddeleyite, 6-12 parts of spodumene, 1-3 parts of B2O3, 5-7 parts of samarium and europium co-doped ZnO, 3-5 parts of silver powder, 0.5-2 parts of yttrium oxide, 0.5-2 parts of lutetium oxide, 3-6 parts of sodium humate, 3-6 parts of sodium polyacrylate and 20-30 parts of water. In the samarium and europium co-doped ZnO, the doping amount of samarium is 1-3 wt%, and the doping amount of europium is 1-3 wt%. According to the high-strength antibacterial domestic ceramic disclosed by the invention, through mutual matching of the components and control of the preparation method, the obtained product has excellent strength and antibacterial performance.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics. More specifically, it relates to a high-strength antibacterial daily-use ceramic and a preparation method thereof. Background technique [0002] Environmental protection has been highly valued by people all over the world today, and antibacterial materials are an important part of environmentally friendly materials. Air and water are polluted and need to be purified; the airtightness of the current residence is very high, the ventilation is poor, and the indoor temperature is relatively high. Such an environment provides good conditions for the reproduction and growth of mold and bacteria. People need to use antibacterial products to achieve cleanliness the goal of. [0003] Daily-use ceramics with antibacterial properties prevent food from rotting to a certain extent, effectively reduce the spread of viruses such as hepatitis B and E. coli, and improve the comfort and safety of life...
