Description

一种用于制造光催化抗菌陶瓷的喷涂液
技术领域
本发明涉及抗菌陶瓷生产技术领域，尤其涉及一种用于制造光催化抗菌陶瓷的喷涂液。
背景技术
内墙瓷砖是厨房、洗手间、医院病房、手术室及游泳池等场所使用最普遍的装修材料。此类场所多为阴湿环境，通风不畅且含有丰富的营养物质，极利于细菌的滋生、繁殖和传播，因而是各类疾病交叉传染的主要场所。1966年夏，日本西部由于一次病原性大肠杆菌(O-157)所引起的食物中毒事件，致使1800人住院并导致12人死亡，引起日本各界的极大震惊。此后不久，东京大学藤岛教授所带领的研究小组首次发现，在涂有TiO2薄膜的玻璃片上涂布3×104个大肠杆菌的菌悬液，经紫外光照射1小时后，细菌无一存活。而不涂TiO2薄膜的相同样品，光照4小时后仅有50％的细菌被杀灭。这一发现首次将光催化作用推及玻璃、陶瓷等建材表面的灭菌研究。接着东陶公司将涂有TiO2薄膜的卫生洁具推向市场。
但是，现有的抗菌陶瓷表面的TiO2薄膜的的热处理温度较低，使得TiO2薄膜与基础陶瓷的釉面结合的不够牢固，使用过程中很容易脱落，从而影响到抗菌陶瓷在实际应用中的抗菌性能和寿命。
发明内容
针对现有技术中的上述不足，本发明提供了一种用于制造光催化抗菌陶瓷的喷涂液，能够在1323K高温下仍然可以抵御油料中的碱性金属、离子的侵蚀，仍然可以保持较强的光催化活性。
为了达到上述发明目的，本发明采用的具体方案为：
一种用于制造光催化抗菌陶瓷的喷涂液，包括改性的TiO2溶液和占改性TiO2溶液重量5-6％的担载型TiO2粉末催化剂组成。
作为改进，所述改性的纳米TiO2溶胶包括以下步骤：
(1)将钛酸四丁酯-无水乙醇溶液预混合，将混合液使用搅拌机进行30分钟强烈搅拌，使其完成水解；
(2)将预混合后的正硅酸乙酯-无水乙醇溶液在搅拌下缓慢滴入水解体系，并继续搅拌，然后滴加5％的硝酸锆溶液，陈化1小时；
(3)再加入4％的磷酸即可制备出改性的TiO2前驱体；
(4)将改性的TiO2前驱体经过105℃红外干燥10分钟后，即制备出改性的TiO2粉体；
将得到的改性的TiO2粉体溶于水中，即可得到改性的TiO2溶液。
作为改进，所述担载型TiO2粉末催化剂为担载Pt、Fe、Rh、V之任一种金属或者金属氧化物的锐钛矿型TiO2粉末。
作为改进，所述担载型TiO2粉末的制备方法包括：取锐钛矿型TiO2粉末于N2气流中、600-700℃预处理1.5-3.5小时，再降温至250-450℃恒温2-4小时后自然降温待用；按TiO2重量的0.1-1％的Pt担载量取H2PtCl6·6H2O溶于二次水中并移入光反应器中；将上述处理过的TiO2粉末搅拌下缓慢加入反应器中，再用N2吹扫10-20分钟后封闭光反应器，在紫外光照射下还原1-2小时，所得浆料经过滤洗涤至无Cl-后于100-150℃干燥12-24h，得Pt担载型TiO2粉末催化剂。
本发明的有益效果为：
本发明所制得的光催化抗菌陶瓷的喷涂液，能够在1323K高温下仍然可以抵御油料中的碱性金属、离子的侵蚀，仍然可以保持较强的光催化活性，可以提高抗菌瓷砖的使用寿命，节省了成本和资源。
