| titleOfInvention | Method for preparing superabsorbent resin particles using superabsorbent resin powder and superabsorbent resin particles prepared by the method |
| abstract | The present invention relates to a method for preparing water-absorbent resin particles using superabsorbent resin powder and the superabsorbent resin particles prepared by the method. The method comprises: (1) placing 50-100 parts by weight of superabsorbent resin powder in a container, and adding 1.25-2.5 parts by weight of dispersant, 0.1-0.25 parts by weight of binder and 1.5-3 parts by weight of solvent while stirring until the volume of the superabsorbent resin powder expands by 3 to 10 times to obtain a pretreated material; (2) the pretreated material obtained in step (1) is heated at 140 to 200° C.; (3) The pretreatment material after the heat treatment in step (2) is pulverized into particles, mixed with 1.5-3 parts by weight of a fixing agent, and then 1-2 parts by weight of silicon dioxide is added to prepare superabsorbent resin particles. In the present invention, the superabsorbent resin particles with low density, fast absorption speed, fast diffusion speed and good water retention performance are prepared by the method, and the profit margin is improved. |
