The preparation method comprises the following steps: S1, carbonizing rice husks, and cleaning and drying bauxite; s2, uniformly mixing and stirring activated carbon and bauxite, mixing for 8 hours by taking absolute ethyl alcohol as a medium, adding an adhesive, and continuously performing ball milling for 2 hours to obtain slurry; s3, dipping the slurry onto nano silicon dioxide, then putting the dipped nano silicon dioxide into a mold, and performing low-temperature hot pressing on a press vulcanizer to obtain a carbon-aluminum oxide-silicon dioxide composite material; and S4, performing ball milling on the composite material to obtain slurry, then putting the slurry into a spinning device, performing extrusion to form a film, and finally putting the film into a hot pressing furnace to obtain the ceramic film. Activated carbon, silicon dioxide and aluminum oxide in bauxite are well combined through an impregnation high-pressure process to prepare a composite material, then the composite material is used as a ceramic membrane slurry raw material, and after ball milling is conducted on the composite material, a carbon-aluminum oxide-silicon dioxide ceramic membrane is successfully prepared through a spinning device. And the adsorbability of the alumina-silica ceramic membrane is improved.
本发明公开了S1、将稻壳炭化并把铝矾土清洗干燥;S2、将活性炭和铝矾土混合搅拌均匀,并以无水乙醇为介质混合8h后,加入黏结剂继续球磨2h得到浆料;S3、将浆料浸渍至纳米二氧化硅上,然后将浸渍后的纳米二氧化硅放入模具中,在平板硫化机上低温热压,得到碳氧化铝二氧化硅复合材料;S4、将复合材料球磨得到浆料,然后将浆料放在纺丝装置中挤出成膜,最后将放入到热压炉中,得到陶瓷膜。本发明通过浸渍高压工艺,很好的将活性炭和二氧化硅以及铝矾土中的氧化铝结合起来,制备出复合材料,然后将复合材料做为陶瓷膜浆液原料,将其球磨后,通过纺丝装置,成功制备出了碳氧化铝二氧化硅陶瓷膜,碳的加入,提高了氧化铝二氧化硅陶瓷膜的吸附性。
