The invention relates to a method for producing super-absorbent particles, comprising the steps of polymerizing a monomer preparation, drying the aqueous polymer gel obtained, grinding, classifying and thermal surface post-curing, the monomer preparation being obtained by mixing an aqueous monomer solution and a foamed aqueous surfactant solution. 本发明涉及一种制备超吸收性颗粒的方法，所述方法包括以下步骤：聚合单体制剂、干燥所获得的水性聚合物凝胶、研磨、分级和热表面后交联，所述单体制剂通过混合单体水溶液和经发泡的表面活性剂水溶液来获得。
