The Room Temperature Synthesis and Performance Study of Cationic Polycarboxylate Superplasticizer

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.
