摘　　要：根据"分子设计"原则,用自制单体设计、合成一种新型氨基磺酸盐高效减水剂。经红外光谱分析表明,增加了分子中的-SO3基团数量,引入了-COOH,有效地提高了减水剂的分散能力,合成产物的分子结构与设计的分子结构基本一致。同时对该高效减水剂进行了吸附量、ζ-电位的测定,进一步解释了该减水剂性能优越的机理。Based on the rule of molecular design, a new aminosulfonic acid -based superplasticizer was been synthesized by designment of monomer made by oneself.IR illustrated that the quantities of- SO~ group of the molecular and increased carboxyl group, more impor- tant,the dispersion capacity of the superplasticizer was effictively improved.The molecular structure of the synthesized product was in ac- cord with in the plan.Absorption capacit and zeta potential of the superplasticizer were also determined,the mechanism of superior perfor- mance were studied.
