Zirconium pyrophosphate porous ceramic material based on foaming method and preparation method thereof

The invention relates to a zirconium pyrophosphate porous ceramic material based on a foaming method and a preparation method thereof. According to the technical scheme, ammonium dihydrogen phosphate and zirconium oxide are mixed to obtain a mixture I, the mixture I is subjected to ball milling and drying, heat preservation is conducted for 1-5 hours under the condition of 250-750 DEG C, crushing is conducted, and zirconium pyrophosphate powder is obtained; the zirconium pyrophosphate powder is mixed with deionized water to obtain a mixture II; the mixture II is mixed with a polycarboxylic acid composite dispersant, and ball milling is conducted to obtain zirconium pyrophosphate slurry; a nonionic foaming agent is added into the zirconium pyrophosphate slurry, and stirring is conducted to obtain foamed slurry; a gelatin solution is added into the foamed slurry, stirring is conducted, the stirred material is poured into a mold, and standing and drying are conducted to obtain a zirconium pyrophosphate porous ce
