| titleOfInvention | Process for preparing water absorbent resin using hydrolysis catalyst |
| abstract | The present invention relates to a method for preparing an absorbent resin, wherein by using a polyhydric alcohol compound that can be hydrolyzed in the presence of a hydrolysis catalyst as an internal crosslinking agent, the granularity of the initial gel-type resin, which is a problem of the conventional method for preparing an absorbent resin, is broken down. It is possible to provide a method for preparing an absorbent resin suitable for mass production that can solve the difficulties of the present invention and improve the absorbent capacity. Method for producing an absorbent resin according to the present invention comprises the steps of (a) internally cross-linking a partially neutralized acrylic acid monomer solution containing an acid group with a polyhydric alcohol type first crosslinking agent to produce a gel resin; (b) subdividing the gel resin to produce a fine gel resin; (c) adding a hydrolysis catalyst to the fine gel resin to produce hydrolyzed microgel resin; (d) drying, pulverizing and classifying the hydrolyzed microgel resin to produce a base resin powder; And (e) surface-crosslinking the base resin powder with a second crosslinking agent to produce an absorbent resin. |
