MANUFACTURING METHOD OF HIGHLY ABSORPTIVE RESIN CAPABLE OF RESOLVING THE PROBLEMS OF EXISTING METHOD WHICH ARE THE UNUNIFORM SIZE OF SEPARATED GEL TYPE RESIN AND LONG PULVERIZING TIME

摘要

PURPOSE: A manufacturing method of highly absorptive resin is provided to improve absorbing capacity by dividing the pulverizing process of gel type resin to crude pulverization process and fine pulverization process, and suitable for mass production.;CONSTITUTION: A manufacturing method of highly absorptive resin comprises: a step of manufacturing crude-pulverized gel type resin by internal crosslinking and polymerization of partially neutralized acrylic acid containing acidic group, and the crude pulverization of the gel type resin; a step of manufacturing micro gel type resin by the fine pulverization of the crude-pulverized gel type resin; a step of drying the micro gel type resin; a step of manufacturing base resin powder by pulverizing and distributing the micro gel type resin; and a step of manufacturing absorptive resin by surface-crosslinking the base resin powder with a second crosslinking agent.;COPYRIGHT KIPO 2012
