Huiyun Titanium Industry applied for a preparation method and application patent for modified ultra-fine titanium dioxide. Modified ultra-fine titanium dioxide can improve the antibacterial property and mechanical strength properties of ceramic glazes

On June 14, 2024, Tianyuncha intellectual property information showed that Guangdong Huiyun Titanium Co., Ltd. applied for a project titled "Preparation Method and Application of Modified Ultrafine Titanium Dioxide" with the public number CN202410369001.7, and the application date is March 2024.

The patent abstract shows that the preparation method includes the following steps: mixing 7.5 - 8.2 parts by volume of ethanol and 10 parts by volume of tetraethyl titanate, and adjusting the pH to 4 - 5 to obtain a first mixed liquid; mixing the templating agent with 7.5 - 8.2 parts by volume of ethanol, 2.1 - 2.4 parts by volume of water, 2.8 - 3.2 parts by volume of glacial acetic acid and 1.2 - 1.5 parts by volume of silane coupling agent to obtain a second mixed liquid; The second mixed solution is slowly dropped into the first mixed solution to obtain nano titanium dioxide gel; after drying, calcination to obtain rutile nano titanium dioxide; and the rutile nano titanium dioxide is subjected to silver loading treatment to obtain modified ultra-fine titanium dioxide. As a glaze additive, the modified ultra-fine titanium dioxide of the invention can improve the quality of ordinary quality ceramic bodies and improve the antibacterial property and mechanical strength properties of the glaze.
