Title (EN) METHOD FOR PREPARING SUPER ABSORBENT RESIN, AND SUPER ABSORBENT RESIN OBTAINED BY SAME METHOD
(FR) PROCÉDÉ DE PRÉPARATION D'UNE RÉSINE SUPERABSORBANTE, ET RÉSINE SUPERABSORBANTE OBTENUE PAR CE PROCÉDÉ
(KO) 고흡수성 수지의 제조 방법 및 이러한 방법으로 얻은 고흡수성 수지
Abstract:
(EN) 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.
(FR) La présente invention concerne un procédé permettant de préparer une résine superabsorbante, et une résine superabsorbante obtenue par ledit procédé, le procédé comprenant : la mise en œuvre d'un mélange à sec d'une poudre fine et d'un liant polymère spécifique en phase poudre au moment du réassemblage de la poudre fine générée pendant un procédé de fabrication d'une résine superabsorbante, le procédé n'exigeant donc pas une étape de séchage à l'état humide traditionnellement exigée après réassemblage de la poudre fine, et pouvant ainsi réduire la perte de chaleur, améliorer la productivité et donner une résine superabsorbante, dont toutes les propriétés basiques d'absorption sont excellentes.
(KO) 본 발명은 고흡수성 수지의 제조공정 중 발생하는 미분 재조립시 미분과 분말 상의 특정 고분자 바인더의 건조 흔합을 진행함으로써, 기존과 같이 미분 재조립후의 수분 건조 공정이 불필요하여 열손실을 줄일 뿐 아니라 생산성도 향상시키며 기본적인 흡수 물성이 모두 우수한 고흡수성 수지의 제조 방법 및 이러한 방법으로 얻은 고흡수성 수지가 제공된다.
