Abstract: front page image
(EN)The present invention relates to a preparation method for a super absorbent resin. The preparation method for the super absorbent resin according to one aspect of the present invention comprises the steps of: obtaining a ground hydrogel polymer in the process of preparing the super absorbent resin; thereafter injecting, into the ground polymer, a surface cross-linking solution comprising a surface cross-linking agent, alcohol, and ionic liquid; and crosslinking the surface of the ground polymer. The preparation method for the super absorbent resin uses the ionic liquid, and thus, if a lower alcohol is not used or is used together with the ionic liquid, is capable of minimizing the amount of the alcohol, thereby having the effects of reducing costs and reducing additional drying treatment, and furthermore is capable of preparing the super absorbent resin having an excellent product physical property by controlling swelling of a gel.
(FR)La présente invention porte sur un procédé de préparation pour une résine superabsorbante. Le procédé de préparation pour la résine superabsorbante selon un aspect de la présente invention comprend les étapes consistant à : obtenir un polymère hydrogel broyé dans le processus de préparation de la résine superabsorbante ; après cela injecter, dans le polymère broyé, une solution de réticulation de surface comprenant un agent de réticulation de surface, un alcool et un liquide ionique ; et réticuler la surface du polymère broyé. Le procédé de préparation pour la résine superabsorbante utilise le liquide ionique et donc, si un alcool inférieur n'est pas utilisé ou s'il est utilisé conjointement avec le liquide ionique, il permet de réduire au minimum la quantité de l'alcool, ce qui de cette manière a pour résultat de réduire les coûts et de réduire le traitement de séchage supplémentaire, et en outre il permet de préparer la résine superabsorbante ayant une excellente propriété physique de produit par maîtrise du gonflement d'un gel.
(KO)본 발명은 고흡수성 수지의 제조 방법에 관한 것이다. 본 발명의 일 측면에 따른 고흡수성 수지의 제조방법은, 고흡수성 수지를 제조하는 과정에서 분쇄된 함수겔상 중합체를 얻은 다음, 상기 분쇄된 중합체에 표면 가교제, 알코올, 및 이온성 액체를 포함하는 표면가교액을 분사하여 상기 분쇄된 중합체의 표면을 가교하는 단계를 포함한다. 이러한 고흡수성 수지의 제조방법은 이온성 액체를 사용하여 저급 알코올을 사용하지 않거나 함께 사용되는 경우 그 양을 최소로 할 수 있어 비용절감 및 추가적인 건조처리를 줄일 수 있는 효과가 있고, 겔의 팽윤을 조절하여 제품 물성이 우수한 고흡수성 수지를 제조할 수 있다.
