Antibacterial ceramic glaze and production process thereof
The invention discloses an antibacterial ceramic glaze and a production process thereof, and belongs to the technical field of ceramic production, and the production process comprises the following steps: carrying out ball milling on a glaze base material until the particle size reaches 250 meshes, adding a compound antibacterial agent, an adhesive and water, and continuously carrying out ball milling to obtain the antibacterial ceramic glaze, the compound antibacterial agent is prepared by the following steps: adding calcium nitrate, yttrium nitrate, silver nitrate and sodium dodecyl benzene sulfonate into deionized water, stirring until solids are completely dissolved, adjusting the pH value by using ammonia water, adding a diammonium hydrogen phosphate aqueous solution while stirring, filtering after stirring and standing, and cleaning and drying a precipitate to obtain the compound antibacterial agent. Silver and yttrium loaded hydroxyapatite is prepared by using a hydrothermal method, and silver ions and yttrium ions play a synergistic antibacterial role; ca < + > in hydroxyapatite can be subjected to efficient ion exchange with silver and yttrium ions, and it is proved that the ceramic glaze finally prepared through the method has the remarkable antibacterial property on escherichia coli.
本发明公开了一种抗菌陶瓷釉料及其生产工艺，属于陶瓷生产技术领域，包括以下步骤：将釉料基料球磨至粒度达250目筛，向中加入复配抗菌剂、粘合剂和水，继续球磨，得到抗菌陶瓷釉，其中，复配抗菌剂由以下步骤制备：向去离子水中加入硝酸钙、硝酸钇、硝酸银和十二烷基苯磺酸钠，搅拌至固体完全溶解，用氨水调节pH，向中搅拌加入磷酸氢二铵水溶液，搅拌静置后过滤，沉淀经清洗烘干后，得到复配抗菌剂。本发明利用水热法制备了载银和钇的羟基磷灰石，银离子和钇离子发挥协同抗菌作用；本发明中的羟基磷灰石中的Ca+可以与银和钇离子进行高效的离子交换，经验证，本发明最终制备陶瓷釉料对于大肠杆菌具有显著的抗菌性。
