The invention discloses a method for preparing nitrogen and potassium containing super absorbent resin by utilizing a carboxymethyl sunflower disc. The method for preparing the nitrogen and potassium containing super absorbent resin by utilizing the carboxymethyl sunflower disc is characterized by comprising the following steps: mixing a certain amount of sodium hydroxide solution with sunflower disc powder in a three-opening bottle, soaking, so that the sunflower disc is fully swelled; dropwise adding the sodium hydroxide solution into the mixture, stirring for 1 hour in a water bath kettle at the temperature of 30 DEG C, then dropwise adding a sodium monochloroacetate solution in reaction mixture, carrying out reaction for 2 hours, then pouring the mixture after reaction is finished into a stainless steel disc, carrying out reaction in a drying oven, washing with 70% ethyl alcohol after drying is finished, then drying, and smashing, so that the carboxymethyl sunflower disc is obtained; uniformly mixing acrylic acid and potassium acrylate, acrylamide, the carboxymethyl sunflower disc, potassium persulphate, N,N'-methylene bisacrylamide and deionized water, protecting by adopting nitrogen, heating in water bath and stirring, stopping stirring at a polymerization temperature, continuously heating, insulating and carrying out reaction for 2 hours in boiling water bath, stopping introduction of nitrogen, taking out reactants, placing the reactants into a blast drying oven at the temperature of 40-60 DEG C to be dried to constant weight, and smashing, so that the nitrogen and potassium containing super absorbent resin product is obtained.
