| titleOfInvention | Method for producing water-absorbing gel particles |
| abstract | PROBLEM TO BE SOLVED: To provide a novel method for producing water-absorbing gel particles from which gel particles having a desired particle size can be easily obtained by a simple method. SOLUTION: The water-absorbing gel particles have a step of swelling the water-absorbing gel using an aqueous solvent, a step of mechanically pulverizing, and a step of precipitating the water-absorbing gel particles using an organic solvent compatible with the aqueous solvent. It is a manufacturing method. In the step of swelling the water-absorbing gel with the aqueous solvent, it is preferable to obtain water-absorbing gel particles by swelling the water-absorbing gel with 100 parts by weight or more of the aqueous solvent per 1 part by weight of the water-absorbing gel. Further, in order to precipitate the water-absorbing gel particles with an organic solvent compatible with the aqueous solvent, it is preferable to mix the organic solvent with the water-absorbing gel while stirring the organic solvent. One part by weight of the swollen water-absorbing gel is mixed with 4 parts by weight of the organic solvent. It is preferred to use at least one part. As the water-absorbing gel of the raw material, it is preferable to use a three-dimensional network structure of a natural polymer compound or a derivative thereof, particularly a three-dimensional network structure of a cellulose derivative. |
