An antibacterial ceramic toilet article and a method for manufacturing the same
By immobilizing silver ions on a silica carrier and controlling the deposition of zinc salt hydrolysis products, combined with a double-layer glaze structure design, the problem of easy volatilization and reduction of silver-based antibacterial agents at high temperatures is solved. This achieves the synergistic antibacterial effect of silver and zinc and improves the wear resistance of the glaze, meeting the high-frequency use requirements of sanitary ware.

Abstract
本发明公开了一种抗菌陶瓷马桶制品及其制备方法。该方法先将实心二氧化硅微球浸渍于硝酸银水溶液中，经热处理使银离子以固载于二氧化硅表面；再将载银二氧化硅微球分散于含锌盐和沉淀剂的溶液中，控制pH值为7.5至9.5、温度为60℃至90℃，使锌盐水解产物原位沉积，经第二热处理得到复合抗菌剂。将复合抗菌剂与基础釉料混合制成功能层釉浆，另配制含氧化铝的保护层釉浆，依次施涂于陶瓷马桶坯体表面，经1080℃至1150℃烧成，得到具有优异抗菌性能和耐久性的抗菌陶瓷马桶制品。
