Microfiltration ceramic coating liquid and preparation of interlayer-free aluminum oxide ceramic microfiltration membrane
The invention relates to the technical field of inorganic ceramic membranes, in particular to microfiltration ceramic coating liquid and preparation of an intermediate-layer-free aluminum oxide ceramic microfiltration membrane. According to the specific technical scheme, the microfiltration ceramic coating liquid comprises aluminum oxide powder, an adhesive, a dispersing agent and boehmite sol, the adhesive is polyvinyl alcohol, and the dispersing agent comprises polyacrylic acid and nitric acid. When the microfiltration ceramic coating liquid provided by the invention is applied to preparation of a ceramic membrane, a middle transition layer is not needed, so that the production time and cost of the ceramic microfiltration membrane are reduced.
本发明涉及无机陶瓷膜技术领域，具体涉及一种微滤陶瓷涂膜液及无中间层氧化铝陶瓷微滤膜的制备。具体技术方案为：一种微滤陶瓷涂膜液，包括氧化铝粉体、粘合剂、分散剂和勃姆石溶胶，所述粘合剂为聚乙烯醇，所述分散剂包括聚丙烯酸和硝酸。采用本发明提供的微滤陶瓷涂膜液应用于制备陶瓷膜，可无需中间过渡层，从而减少陶瓷微滤膜的生产时间和成本。
