Nano antibacterial ceramic doped with metal oxide and preparation process thereof
The invention belongs to the field of functional ceramics, and particularly relates to a metal oxide doped nano antibacterial ceramic and a preparation process thereof. According to the nano antibacterial ceramic, a green body is prepared from the following raw materials: kaolin, diatomite, montmorillonite, soapstone, bone ash, natural crystal, aluminum dioxide, a metal oxide doped nano antibacterial agent, polyvinyl alcohol and sodium oxalate. The domestic ceramic product obtained by the invention is smooth and fine in surface, and after high-temperature and long-time firing, the nano antibacterial agent exists in the whole green body and is spontaneously separated out of the green body along with the firing process in the kiln, and meanwhile, the nano antibacterial agent can be quickly released for sterilization; through detection and identification, the antibacterial rate of bacteria such as escherichia coli and staphylococcus aureus reaches 90% or above; various nano antibacterialpowder used by the metal oxide doped nano-antibacterial agent coordinate and cooperate with one another in the aspects of action time, sterilization effect, structural stability and the like to play arole together, and the strength, density and smoothness of an unglazed ceramic green body can be improved.
本发明属于功能性陶瓷领域，具体涉及一种具有掺杂金属氧化物的纳米抗菌陶瓷及其制作工艺。该种纳米抗菌陶瓷，坯体的原料包括高岭土、硅藻土、蒙脱、皂石、骨灰、天然水晶、二氧化铝、掺杂金属氧化物纳米抗菌剂、聚乙烯醇、草酸钠。本发明获得的日用陶瓷制品表面光滑细腻，经过高温、长时间的烧制，使得纳米抗菌剂存在于整个坯体中伴随着窑内烧成过程中自发从坯体内析出，同时能快速释放进行杀菌，经检测鉴定对大肠杆菌、金黄色葡萄球菌等病菌的抗菌率达90％以上；掺杂金属氧化物纳米抗菌剂使用的多种纳米抗菌粉体在作用时间、杀菌效果、结构稳定等方面相互协调、配合，共同发挥作用，并能提高无釉陶瓷坯料的坯体强度、致密度和光洁度。
