NOVELTY - Preparing high water resistance filter material by ball milling method comprises (1) taking the cut polyphenylene isophthalamide (PMIA) fiber and soaking sodium dodecylbenzene sulfonate solution, taking out after ultrasonic treatment, and drying to obtain the pretreated fiber, (2) adding graphite powder to ammonium carbonate solution, soaking the pretreated fiber, transferring the fiber together with the solution to the planetary tank of the ball mill after stirring the solution, setting the rotation speed, and performing the ball milling treatment, (3) taking manganese dichloride tetrahydrate, tin (IV) chloride pentahydrate and zirconium oxychloride octahydrate according to certain molar ratio, adding the resulting mixed solution to the planetary tank after being fully dissolved in deionized water, and continuously ball milling treatment, and (4) taking the fiber after the ball milling, washing with deionized water and with ethanol, and heat treating in tube furnace. USE - The method is useful for preparing high water resistance filter material by ball milling method. DETAILED DESCRIPTION - Preparing high water resistance filter material by ball milling method comprises (1) taking the cut polyphenylene isophthalamide (PMIA) fiber and soaking it in 0.6 mg/ml sodium dodecylbenzene sulfonate solution, taking out after ultrasonic treatment for 8 minutes, and drying it at 80 degrees C for 12 hours to obtain the pretreated fiber, (2) adding graphite powder to 0.2 mol/l ammonium carbonate solution, soaking the pretreated fiber, transferring the fiber together with the solution to the planetary tank of the ball mill after stirring the solution for 15 minutes, setting the rotation speed to 240 revolution/minutes, and performing the ball milling treatment for 36 hours, (3) taking manganese dichloride tetrahydrate, tin (IV) chloride pentahydrate and zirconium oxychloride octahydrate according to certain molar ratio, adding the resulting mixed solution to the planetary tank after being fully dissolved in deionized water, and continuously ball milling treatment for 8 hours, and (4) taking the fiber after the ball milling, washing with deionized water 3 times and ethanol 2 times, drying at 75 degrees C for 24 hours, and heat treating in tube furnace at 200 degrees C for 24 hours to obtain manganese-zirconium-stannous oxalate-reduced graphene oxide (rGO)/PMIA composite functional filter material.
