Nano self-cleaning ceramic glaze and preparation method thereof
The invention relates to a nano self-cleaning ceramic glaze and a preparation method thereof, and belongs to the technical field of ceramic glazes. According to the invention, clay, albite, quartz sand, glass powder, borax and an antibacterial agent are selected and subjected to optimized combination, ball milling, sanding and twice calcination, so that the calcination temperature of the glaze is reduced to 550-600 DEG C. According to the invention, a tetrabutyl titanate solution is sprayed on a dry basic glaze surface, so that tetrabutyl titanate is uniformly distributed on the surface of the basic glaze surface, and the service life of the glaze is prolonged; the mixed solution is sprayed after standing, so that hydrolysate of tetrabutyl titanate and the basic glaze surface are firmly and stably combined and uniformly distributed, the photocatalytic and antibacterial effects of anatase titanium dioxide are exerted to the maximum extent through low-temperature sintering, the glaze surface is flat and easy to clean, meanwhile, after titanium dioxide on the surface is illuminated, the contact angle between the surface of the glaze surface and water drops is greatly reduced, and the service life of the glaze surface is prolonged. The surface of the glaze is completely soaked by water, so that stains on the surface of the glaze can be washed away by water, and the surface of the ceramic is kept clean.
本发明涉及一种纳米自洁的陶瓷釉料及其制备方法，属于陶瓷釉料技术领域。本发明选用粘土、钠长石、石英砂、玻璃粉、硼砂、抗菌剂通过优化组合、球磨、砂磨以及两次煅烧工艺，使得釉料的煅烧温度降低至550‑600℃，本发明在干燥的基础釉面喷雾钛酸四丁酯溶液，使得钛酸四丁酯均匀分布于基础釉面表面，静置后喷雾混合溶液，使钛酸四丁酯的水解物与基础釉面结合牢固稳定并分布均匀，低温烧结最大程度上发挥锐钛矿二氧化钛光催化及抗菌效果，且釉面较平整易清洁，同时，表面的二氧化钛经光照后，釉面表面与水珠的接触角会大大减小，釉面表面完全被水浸润，使釉面表面的污渍能够被水冲洗干净，从而维持陶瓷表面洁净。
