摘要
In this paper,cationic polycarboxylate superplasticizer has been synthesized by using room temperature process with HPEG,AA,DAC and 3-S as the main raw materials.We investigated the effect of the dosage of different raw materials on the dispersing property of polycarboxylate superplasticizer,and we knew that AA:DAC HPEG:3-S=4.5:0.05:1:0.12 was the best molar ratio,the synthesized cationic polycarboxylate superplasticizer had excellent dispersity and mud resistance,and it was superior to commercially available ordinary polycarboxylate superplasticizer
