Air purification ceramic material and preparation method thereof
The invention relates to an air purification ceramic material and a preparation method thereof, and belongs to the technical field of novel structural ceramic materials. According to the invention, 1, 2-propylene glycol is adopted to carry out intercalation modification on pretreated kaolin, the modified kaolin not only retains high adsorption performance of kaolin, but also has high reaction activity of 1, 2-propylene glycol, negative ion powder (tourmaline powder, lanthanum oxide, cerium oxide and nano-zinc oxide) and a photocatalyst are mixed with an amino silane coupling agent, and the modified kaolin has high adsorption performance of kaolin and high reaction activity of 1, 2-propylene glycol. The preparation method comprises the following steps: modifying negative ion powder and a photocatalyst, then reacting with intercalation-modified kaolin, reacting amino in a coupling agent with 1, 2-propylene glycol in the intercalation-modified kaolin to form firm chemical bond combination, and carrying out high-temperature calcination to uniformly distribute the negative ion powder and the photocatalyst between kaolin layers. The high adsorbability of kaolin can adsorb harmful gas in air, the photocatalyst promotes decomposition and purification of kaolin, and meanwhile, the negative ion powder continuously releases negative ions to purify air.
本发明涉及一种空气净化陶瓷材料及其制备方法，属于新型结构陶瓷材料技术领域。本发明采用1,2‑丙二醇对预处理后的高岭土进行插层改性，改性后的高岭土既保留了高岭土的高吸附性能，也具备1,2‑丙二醇的高反应活性，将负离子粉(电气石粉、氧化镧、氧化铈、纳米氧化锌)和光触媒与氨基硅烷偶联剂混合，对负离子粉和光触媒改性，然后与上述插层改性后的高岭土反应，偶联剂中的氨基与插层改性后的高岭土中的1,2‑丙二醇反应，形成牢固的化学键结合，高温煅烧后，高岭土层间均匀分布负离子粉和光触媒，高岭土的高吸附性可吸附空气中的有害气体，光触媒促进其分解净化，同时负离子粉持续释放负离子净化空气。
