Preparation and Application of Modified Graphene Oxide Hexacarbon Polycarboxylic Acid Water Reducing Agent
By adding benzotriazole and forming hydrogen bonds with graphene oxide,temperature sensitivity is reduced.And by controlling the mass ratio of benzotriazole to polyvinylpyrrolidone,modified graphene oxide was produced.And modified graphene oxide,diethylene glycol monovinyl ether,4-mercaptobutyl vinyl ether,unsaturated acid,reducing agent,oxidant,pH regulator,and deionized water were used as raw materials to prepare modified graphene oxide six carbon polycarboxylate water reducer.It has good water reduction rate and net slurry fluidity,and can be evenly dispersed in cement.Therefore,when applied to concrete,it can make the concrete have good slump and compressive strength.
