Abstract

본 발명은 나프톨을 황산화하여 제조하는 몰탈 및 콘크리트용 감수제의 제조방법 및 그 감수제에 관한 것으로서 나프톨을 황산화한 나프톨술폰산에 포름알데히드를 첨가하여 60℃-90℃에서 10-20시간 방응시킨후 미반응 황산을 침석시켜 분리하고 적량의 염기성 물질을 투입중성화하여 제조하며 종래의 감수제보다 시멘트의 유동성이 뛰어난 효과가 있는 것이다.The present invention relates to a method for preparing mortar and concrete sensitizer prepared by sulphating naphthol and a sensitizer thereof. Unreacted sulfuric acid is separated by sedimentation, and an appropriate amount of basic material is prepared by input neutralization, and the flowability of cement is superior to conventional water reducing agents.
