Antibacterial environment-friendly ceramic and preparation method thereof
The invention relates to the technical field of ceramics, and provides antibacterial environment-friendly ceramic and a preparation method thereof. The antibacterial environment-friendly ceramic is prepared from a base material, modified graphite, nano aluminum powder, nano silver, germanium nano particles and metal oxide; and the modified graphite is obtained by mixing and atomizing graphite powder and a silane coupling agent, performing ultraviolet irradiation in a nitrogen environment and performing high-temperature calcination. The modified graphite is added into the ceramic base material, and the modified graphite is obtained by mixing and atomizing the graphite powder and the silane coupling agent, performing ultraviolet irradiation in a nitrogen environment and performing high-temperature calcination. Carbonyl and carbon hydroxyl in the graphite powder are continuously subjected to grafting reaction with silicon hydroxyl formed by hydrolysis of the silane coupling agent under ultraviolet high-energy radiation, so that the obtained modified graphite has high wear resistance, antibacterial effect and dielectric property.
本发明涉及陶瓷技术领域，提供了一种抗菌环保陶瓷及其制备方法，所述一种抗菌环保陶瓷，包括以下组分：基材、改性石墨、纳米铝粉、纳米银、锗纳米颗粒、金属氧化物；改性石墨由石墨粉末与硅烷偶联剂混合并雾化后，在氮气环境中进行紫外线照射后，进行高温煅烧后得到的。本发明在陶瓷基材中添加改性石墨，且改性石墨由石墨粉末与硅烷偶联剂混合并雾化后，在氮气环境中进行紫外线照射后，进行高温煅烧后得到的，石墨粉末中的羰基和碳羟基在紫外高能辐射下与硅烷偶联剂水解形成的硅羟基继续发生接枝反应，使得得到的改性石墨具备高耐磨性和抗菌效果、介电性能。
