Synthesis of a novel polycarboxylic acid water reducing agent and its applications
The polyether monomer LPEG-4000 was synthesized using hexaenol"4-hydroxybutyl vinyl ether".A novel polycarboxylic acid water reducing agent was prepared by free radical polymerization of this monomer with small molecules such as acrylic acid,2-acrylamido-2-methylpropane sulfonic acid(AMPS),sodium methacrylate sulfonate(SMAS),and maleic anhydride(MA),etc.This water reducing agent had good compatibility and enhancement effect.The application test showed that the comprehensive performance of the water reducing agent was obviously superior to that of the conventional polycarboxylic acid water reducing agent,and it could significantly improve the strength of concrete at all stages.
