Synthesis and properties of the polycarboxylate superplasticizer for clay tolerance
ZHONG Lina
Abstract：Polycarboxylate superplasticizer for clay tolerance was synthesized by designing the molecular structure at H2O2-CH3NaO3S.2H2O redox initiation system. It showed the best overall performance when n(AA):n(2-methacryloyloxyethyl phosphate):n [2-(acryloyloxy)ethyl hydrogen phosphate]:n(3-mercaptopropionic acid):n(VPEG) was 2.5:0.2:0.05:0.14:1.0 and the synthesized temperature was 15℃. The experiment results showed that the polycarboxylate superplasticizer had excellent dispersibility,dispersion retention and clay tolerance.
