Surface treatment method for water-absorbing resin and production method for water-absorbing resin |
| abstract |
The present invention provides a surface treatment method for a water-absorbing resin comprising three steps of: 1) a humidifying and mixing step for mixing a base polymer and a surface cross-linking agent solution to obtain a "humidified substance"; 2) a pretreatment step for raising temperature of said humidified substance to obtain a "pretreated substance"; and 3) a surface cross-linking reaction step for cross-linking said pretreated substance to obtain a surface cross-linked "water-absorbing resin"; wherein dew point in the pretreatment step of the above 2) is from 50° C. to 95° C., and temperature of said humidified substance is raised from temperature below the dew point up to a temperature of 10° C. higher than the dew point. |
