The invention discloses a preparation method of completely biodegradable high-absorptivity resin. The preparation method comprises the following preparation steps: S1, mixing a monomer A and a heterocyclic compound comonomer B to obtain a mixed monomer C; wherein the monomer A is liquid and/or molten acrylic acid and/or acrylamide and derivative monomers, and the monomer B is a heterocyclic compound; s2, adding a cross-linking agent and an initiator into the mixed monomer C, and then carrying out polymerization reaction at 13-150 DEG C to obtain a polymeric colloid; and S3, granulating, neutralizing, drying, crushing and screening to obtain the completely biodegradable high-absorptivity resin. The preparation method of the completely biodegradable high-absorptivity resin disclosed by the invention has the following beneficial effects that the SAP comprehensive performance is good, and a relatively high biodegradation rate can be taken into account. 本发明公开了一种可完全生物降解高吸收性树脂的制备方法，包括下述制备步骤：S1将单体A和杂环化合物共聚单体B混合得到混合单体
