The invention discloses a method for preparing a ceramic film, and the method takes a colloidal solution as a raw material and adopts a sol-gel method to prepare the ceramic film. A base material is arranged in a colloidal solution, microgel in the colloidal solution is adsorbed on the surface of the base material, the microgel is further stacked, a gel layer is generated on the surface of the base material in the colloidal solution, the gel layer is dried to obtain the ceramic film, and the process comprises the steps of cleaning the surface of the base material, heating the colloidal solution to 50-90 DEG C for increasing the content of the microgel in the colloidal solution, soaking the base material in the colloidal solution or spraying the surface of the base material to generate thegel layer on the surface of the base material, taking out the base material, reducing liquid carried by the base material when the base material is taken out from the colloidal solution in an air blowing or draining manner, and naturally airing or heating and drying. According to the method, fewer parameters need to be controlled in the technological process, and the quality of the prepared ceramic film is more stable.
本发明公开了一种制取陶瓷膜的方法，是以胶体溶液为原料，采用溶胶‑凝胶法制取陶瓷膜的。置于胶体溶液中的基材，其表面吸附胶体溶液中的微凝胶，微凝胶进一步堆积，使基材表面在胶体溶液中生成凝胶层，干燥该凝胶层得到陶瓷膜，其工艺步骤包括清理基材表面、加热胶体溶液至50～90℃，使胶体溶液中微凝胶的含量增加，然后胶体溶液浸泡基材或喷淋基材表面，在基材表面生成凝胶层，取出后用吹风或沥干方式减少基材从胶体溶液中移出时夹带的液体、自然晾干或加热干燥步骤。上述方法，工艺过程需控制参数较少，而所制得的陶瓷膜的质量更稳定。
