Description

一种抗静电、抗电磁辐射、抗菌陶瓷
技术领域:
本发明涉及一种陶瓷,尤其是一种具有抗菌、抗静电、抗电磁辐射的多功能陶瓷。
背景技术:
目前,特种生产环境要求,如抗静电、抗菌、抗辐射等,都需经过专门的处理。抗静电是采用在地面和墙体埋设导电金属物质,抗辐射需要在墙面和地面铺设防电磁辅射的材料,或用防电磁辅射的涂料进行粉刷,抗菌则需要增加专门的抗菌设备,或在装饰材料内添加抗菌剂。
随着经济的发展,大量电子和生物医药企业的生产环境需要进行抗菌、抗静电、防电磁辐射的处理,否则受静电和电磁辐射的干扰,会严重影响精密仪器设备的运转和产品的校准。另外,人们对生活环境的意识越来越高,对于能够屏蔽电站等高频电磁发射场的电磁辐射的要求越来越大。因此,对具有抗菌、防辐射等特种功能的内、外装饰材料的需求正越来越大。
瓷砖是常用的建筑装潢材料,如果能赋予瓷砖特殊的功能,就能方便、廉价地满足上述这些特殊的装饰要求。目前抗菌瓷砖较为普遍,一般是在瓷砖内添加抗菌剂,但市场上还没有抗静电和抗电磁辐射的瓷砖,更没有将上述三种功能融为一体的多功能瓷砖。
发明内容:
本发明提供一种新型的,集抗菌、抗静电、抗电磁辐射的多功能瓷砖,其主要机理是在Zr-Si-P或Zr-Ti-P结构的陶瓷基料中加入含Na离子的稀土复合磷酸盐材料,经受控的烧结过程,可在陶瓷体内部形成[NZP]结构,[NZP]结构的很大特点就是金属离子在单位晶胞内产生不稳定游离,可以起到干扰、吸收电磁辐射和γ射线的作用。而且,在电场作用下,金属离子的游离即可成为一种定向移动,从而使陶瓷材料具有一定的导电性能,可以将静电导向地面。此外,金属离子的游离特性,可以对生物活性物质产生氧化作用,从而起到灭菌的效果。
下面结合实施例,具体说明本发明瓷砖的制备方法:
将各1mol的Zr2P2O3和SiO2或TiO2细化晶粒微粉,加3%的稀土复合磷酸钠充分搅拌混合,置于填有石墨垫片的钢模具内,迅速加高温至1200℃烧结1小时,然后快速退火,用0.01mol的NaHCO3溶液喷洒降温,待低于50℃后浸入0.01mol的NaHCO3溶液,使Na+得到充分置换,然后取出。再加入0.01%的烧结助剂ZrN,重新加温至400℃反应烧结2小时,再以30℃/h的速度升温至1200℃,继续高温烧结48小时,然后退火降温冷却,即可得到本发明物质。其分子式可以表达为Na3Zr2Si2PO12或NaZr2Ti2P3O12
对最终得到的成品进行测试,其对黄色葡萄球菌的杀灭率达到90%;导电率达到10-7Ω-1.cm-1;电磁辐射和γ射线透过率为20%。[NZP]结构陶瓷最早应用于做催化剂的骨架,而民用方面开发应用很少,近来由于[NZP]独特的结构产生许多功能,其应用开发成果逐渐增多。本发明利用稀土材料制备[NZP]结构陶瓷瓷砖,既是在这一领域进行了有益的赏试。
