Production processes for basic water-absorbent resin and water-absorbing agent, and use thereof |
摘要 |
The present invention provides: a production process for a basic water-absorbent resin to be a main component of a water-absorbing agent which exhibits an excellent water absorption capacity under a load with high productivity; a production process for a water-absorbing agent; and use thereof. The production process for an irregular shape basic water-absorbent resin comprises the step of reacting a basic resin and a crosslinking agent in order to obtain the basic water-absorbent resin, with the process forwarding a crosslinking reaction and pulverizing the resultant product at the same time. The first production process for a water-absorbing agent comprises the step of blending an acidic water-absorbent resin with the basic water-absorbent resin obtained by the above-mentioned process. The second production process for a water-absorbing agent comprises the step of obtaining a mixture of an acidic water-absorbent resin and the basic water-absorbent resin by coexisting with the acidic water-absorbent resin when carrying out the crosslinking reaction and the pulverization in the above-mentioned process.
