Porous aluminum oxide film, porous aluminum oxide composite film containing silver ions and preparation method of porous aluminum oxide composite film
The invention discloses a porous alumina membrane, a silver ion-containing porous alumina composite membrane and a preparation method thereof, and belongs to the technical field of porous inorganic membranes. The problems of complex preparation process and single function of the porous inorganic membrane in the prior art are solved. The preparation method of the porous alumina membrane comprises the following steps: uniformly mixing alpha alumina powder, silicon dioxide fine powder, magnesium oxide powder, soluble starch and clay, uniformly dispersing the obtained mixture in distilled water, soaking the mixture, filtering and drying the mixture, grinding the mixture into fine powder, pressing the obtained fine powder into a membrane, and sintering the powder to obtain the porous alumina membrane. The porous alumina membrane has good permeability and porosity, strong mechanical strength, high thermal stability and narrow pore distribution, and has potential application value in air purification, especially in the aspect of PM2.5 screening protection. By soaking the porous alumina membrane in a silver nitrate aqueous solution or adding a silver ion-molecular sieve composite materialinto the raw materials, a composite membrane with sterilization and bacteriostasis effects can be prepared.
多孔氧化铝膜、含银离子多孔氧化铝复合膜及其制备方法，属于多孔无机膜技术领域。解决了现有技术中多孔无机膜的制备工艺复杂、功能单一的问题。本发明的多孔氧化铝膜的制备方法：先将α氧化铝粉末、二氧化硅细粉、氧化镁粉末、可溶性淀粉和粘土混合均匀，得到的混合物均匀分散于蒸馏水中，浸泡，过滤，干燥，研磨成细粉，然后将得到细粉压制成膜片，烧结，得到多孔氧化铝膜。该多孔氧化铝膜具有很好的渗透性和孔隙率，强的机械强度，高的热稳定性以及窄小的孔分布，在空气净化尤其是对PM2.5筛分防护方面具有潜在的应用价值。通过将多孔氧化铝膜浸泡硝酸银水溶液或在原料中添加银离子‑分子筛复合材料还能够制备具有杀菌抑菌效果的复合膜。
