Super-water-absorbent resin and method for preparing same

The invention relates to super-water-absorbent resin and a method for preparing the same, and belongs to the technical field of the water-absorbent resin. The super-water-absorbent resin comprises water phases and oil phases. The water phases include 30-40 parts of methacrylic acid, 30-40 parts of acrylic acid, 5-10 parts of vinyl cyanide, 2-3 parts of methylene bisacrylamide, 0.5-1.2 parts of hydroxymethyl acrylamide, 1-3 parts of potassium persulfate and 0.2-0.6 part of sodium bicarbonate; the oil phase include 500 parts of methyl silicone oil, 3-5 parts of aliphatic ester and 2-3 parts of hexadecanol organophosphate. The methyl silicone oil with a moderate molecular weight is used as a dispersion medium, the aliphatic ester and the hexadecanol organophosphate are used as dispersing agents, and the bead-shaped super-water-absorbent resin can be prepared by the aid of a reversed-phase suspension polymerization process. The super-water-absorbent resin and the method have the advantages that technologies for p
