Title:
METHOD FOR PREPARING SUPER ABSORBENT RESIN, AND SUPER ABSORBENT RESIN OBTAINED BY SAME METHOD
Document Type and Number:
WIPO Patent Application WO/2019/004653
Kind Code:
A8
Abstract:
The present invention provides a method for preparing a super absorbent resin, and a super absorbent resin obtained by the same method, the method comprising: performing dry blending of fine powder and a specific polymer binder in a powder phase at the time of reassembling the fine powder generated during a manufacturing process of a super absorbent resin, so that the method does not require a moisture drying step conventionally required after reassembly of the fine powder, and thus can reduce heat loss, improve productivity, and achieve a super absorbent resin, all basic absorption properties of which are excellent.
