Porous ceramic microbead based on photocuring molding, preparation method and application thereof
The invention belongs to the technical field of inorganic non-metallic materials, and discloses a ceramic microbead based on photocuring molding, a preparation method and application thereof. The method comprises the following steps of: preparing a ceramic suspension from ceramic powder and deionized water, adjusting the pH value to 5 or below, carrying out ball milling, adding deionized water, performing diluting to 30-40vol%, adding a pore forming agent, a surface modifier and organic oil in the dilution process, and performing stirring to complete emulsification to prepare a porous ceramicslurry; adding light-induced resin and a photoinitiator into the porous ceramic slurry, and continuously performing stirring to obtain a photocured porous ceramic slurry; dropwise adding the ceramic slurry into a super-amphiphobic ceramic bowl, performing rotating at a high speed, and conducting irradiating and curing by using a UV lamp; and performing calcining at 1500-1800DEG C in a protective atmosphere to obtain the porous ceramic microbead. The preparation speed of the method based on photocuring molding is higher, and the porous ceramic microbead has the advantages of higher beading degree and high porosity, and can be applied to the field of catalysis or oil-water separation.
本发明属于无机非金属材料技术领域，公开一种基于光固化成型的陶瓷微珠及其制备方法和应用。该方法是将陶瓷粉末与去离子水配成陶瓷悬浮液，调节pH降低至5以下，球磨后加入去离子水稀释到30～40vol％，在稀释过程中加入造孔剂、表面改性剂和有机油搅拌，完成乳化，制得多孔陶瓷浆料；在多孔陶瓷浆料中加入光引树脂和光引发剂，持续搅拌得到光固化的多孔陶瓷浆料；将该陶瓷浆料滴加到超双疏陶瓷碗中并高速旋转，利用UV紫外灯照射固化。在保护气氛下，在1500～1800℃煅烧，制得多孔陶瓷微球。本发明的基于光固化成型的方法的制备速度更快，孔陶瓷微珠具有成球度更高且孔隙率高的优点，可在催化或油水分离领域中应用。
