Preparation method of anti-fouling antibacterial ceramic
The invention relates to the field of domestic ceramic preparation, in particular to a preparation method of anti-fouling and antibacterial ceramic. The preparation method comprises the following steps: reacting zinc oxide, calcium oxide and aluminum hydroxide with phosphoric acid, doping rare earth metal ions to prepare a composite antibacterial material, mixing the composite antibacterial material with a ceramic frit to prepare a ceramic base material, and coating the ceramic base material with titanium dioxide sol; coating the obtained sol on the surface of a ceramic tile, and carrying outheat treatment to obtain the antibacterial ceramic coated with a titanium dioxide film. The process can reduce the water absorption rate of the ceramic, reduce cracks and pores on the surface and improve the surface density of the ceramic, and is a very effective anti-fouling and antibacterial means; the anti-fouling antibacterial ceramic provided by the invention has good impact resistance, wearresistance and acid and alkali resistance, also has the functions of disinfection, deodorization, sterilization and the like, can effectively kill residual escherichia coli and other harmful bacteriawhen being in contact with a human body, and has a good easy-to-clean function, so that the effects of reducing odor, preventing dirt regeneration and saving water are achieved.
本发明日用陶瓷制备领域，具体关于一种防污抗菌陶瓷的制备方法；本发明用氧化锌，氧化钙和氢氧化铝与磷酸反应后掺杂稀土金属离子后制备得到复合抗菌料，与陶瓷熔块混合后制备的陶瓷基料后涂覆二氧化钛溶胶；所获得的溶胶涂在瓷砖表面，经过热处理获得涂覆有二氧化钛薄膜的抗菌陶瓷。该工艺能够降低陶瓷吸水率，减少表面的裂纹和气孔，提高陶瓷表面致密度，是一种非常有效的防污抗菌手段；本发明的防污抗菌陶瓷具有良好的抗冲击性、耐磨性和耐酸碱的性能，又要具备消毒、除臭、灭菌等功能，能有效杀灭与人体接触时残留的大肠杆菌及其他有害细菌，且具有较好的易清洁功能，从而达到减少臭味、防止污垢再生，节水的效果。
