摘要
以对氨基苯磺酸钠(sodium p-aminobenzensulfonate, AS)为原料合成了4-(N,N-二甲基氨基)苯磺酸钠(sodium p-dimethylaminobenzenesulfonate,SDMAS),NMB对其结构进行了表征,并以此单体为原料合成了一种新的氨基磺酸盐类超塑化剂SDMAS,在mw／mc=0．29,SDMAS质量分数掺量为 0．5％时,水泥净浆流动度达到219mm。
Sodium p-dimethylaminobenzenesulfonate was pre-pared by sodium p- aminobenzensulfonate, and the molecular structures of the polymeric surfactants were characteized by NMR spectrum. Aminosulfonic-based superplasticizer SDMAS was synthesized by the sodium p-dimethylaminobenzenesulfonate. When w/c=0. 29 and the dosage of SDMAS is 0.5%, the fluidity of cement paste is 219 mm.
