Summary: | The invention relates to a preparation method of a disc aluminum oxide filter membrane used for dynamic cross flow filtration, and belongs to the technical field of advanced ceramic preparation. The preparation method comprises the following steps: stirring an adhesive to be dissolved into warm water, adding an aluminum oxide powder I, kaolin and a pore-forming agent in sequence, and mixing the aluminum oxide powder I, kaolin and pore-forming agent uniformly; carrying out drying and sieving, and then carrying out compression molding to form a bisque; using an aluminum oxide powder II, kaolin and the adhesive to be configured into a thick sizing agent, spraying the thick sizing agent on the outer edge of the bisque, and adhering the two bisques together; sintering to obtain a supporting body; weighing aluminum oxide powder II, kaolin, a dispersing agent and the adhesive, adding deionized water, and grinding to obtain a first membrane coating solution; spraying to the first membrane coating solution to the oute |
