Preparation method of porous quartz ceramic filter material
The invention discloses a preparation method of a porous quartz ceramic filter material, which comprises the following steps: by using high-purity quartz sand as a raw material and a silane coupling agent as a surface modifier, preparing a silane coupling agent ethanol solution, spraying the silane coupling agent ethanol solution into high-speed stirred quartz sand in a mist form, and stirring anddrying to obtain surface-modified quartz sand; by taking quartz sand as a raw material and silica sol as a binder, uniformly stirring surface-modified quartz sand and a silica sol aqueous solution, and granulating to obtain a granulated material with a certain granularity; and preparing a porous quartz ceramic green body from the granulated material through compression molding, and calcining thegreen body at 1100-1300 DEG C to obtain the porous quartz ceramic filter material. The porous quartz ceramic filter material prepared by the invention is high in structural strength, not easy to damage, multiple in open pores, uniform in distribution and high in water flux.
