UNSATURATED POLYETHYLENEGLYCOL WITH URETHANE BOND AND POLYCARBOXYLIC ACID TYPE COPOLYMER POLYMERIZED THIS FOR CONCRETE ADMIXTURE
The present invention relates to a polycarboxylic acid-based copolymer having a novel chemical structure, specifically, to a copolymer having excellent dispersibility and excellent early strength expression, and a concrete admixture and cement concrete comprising the same. More specifically, the present invention relates to: a copolymer manufactured by conducting urethane reaction of unsaturated polyethylene glycol with an isocyanate compound to produce unsaturated polyethylene glycol having urethane bond and copolymerizing unsaturated polyethylene glycol having urethane bond with an anionic organic compound; and a concrete admixture and cement concrete comprising the same.
본 발명은 새로운 화학구조를 갖는 폴리카르본산계 공중합체에 관한 것으로, 분산성이 뛰어나고 조기강도 발현성이 우수한 공중합체, 이를 포함하는 콘크리트 혼화제 및 시멘트 콘크리트에 관한 것이다. 상세하게는 불포화 폴리에틸렌글리콜과 이소시아네이트 화합물을 우레탄 반응하여 우레탄 결합을 가진 불포화 폴리에틸렌글리콜을 생성하고 이 우레탄 결합을 가진 불포화 폴리에틸렌글리콜을 음이온성 유기화합물과 공중합하여 제조한 공중합체 및 이를 포함하는 콘크리트 혼화제 및 시멘트 콘크리트에 관한 것이다.
