A method for preparing a super absorbent polymer. After acrylic acid or sodium acrylate is neutralized with a base, a pre-crosslinking agent and an initiator are added to perform a polymerization reaction; a hydrogel is obtained, and then dried and pulverized. At the same time as the colloidal particles, the dispersed fine powder is also produced. The fine powder is subjected to secondary granulation. During the secondary granulation, fumed silica is added and then granulated together with the pulverized gel particles. The particles are mixed into a heat treatment liquid composed of water and a post-crosslinking agent to perform surface treatment, thereby obtaining the super absorbent polymer.
