| titleOfInvention | Polycarboxylate superplasticizer for improving rheological property of cement paste and preparation method thereof |
| abstract | The invention discloses a polycarboxylic acid water reducer for improving rheological property of cement paste, which is prepared from a first mixture, unsaturated polyether, hydroxyethyl methacrylate phosphate, unsaturated acid, a compound A, an initiator, a molecular weight regulator and water through copolymerization reaction. The method comprises the steps of carrying out ester exchange reaction on alkylphenol polyoxyethylene and unsaturated carboxylic ester to obtain an esterification product with a benzene ring; the esterification product is copolymerized with unsaturated polyether, a compound A and hydroxyethyl methacrylate phosphate, so that a benzene ring, a phosphate group and an imide structure are introduced into a branched chain of a polycarboxylate superplasticizer molecule, the rheological property of concrete can be improved, and the stability, the fluidity and the like of slurry are improved. |
