The invention relates to a preparation method of organic amphoteric copolymerized macromolecular interpenetrating network gel. According to the method, methacryloyloxyethyl trimethyl ammonium chloride, beta-hydroxypropyl methacrylate and jasmonic acid are used as comonomers; polyethylene glycol dimethacrylate is used as a cross-linking agent; potassium persulfate-sodium hydrogen sulfite is used as an initiator; a copolymerization reaction is carried out in deionized water to obtain organic amphoteric copolymerized macromolecular first network gel; the first network gel is swelled in an aqueous solution confected by ferulic acid, threose, dimethylaminoethyl acrylate, trimethylolpropane trimethylacrylate and deionized water; monomers and a cross-linking agent in the aqueous solution generate copolymerization and esterification reactions under the action of potassium persulfate and pyridoxol hydrochloride; the organic amphoteric copolymerized macromolecular interpenetrating network gel is finally obtained. 本发明涉及
