| titleOfInvention | High-water-reduction low-sensitivity polycarboxylate superplasticizer and preparation method thereof |
| abstract | The invention discloses a high water-reducing low-sensitivity polycarboxylate superplasticizer and a preparation method thereof, wherein the molecular weight of the polycarboxylate superplasticizer is 10000-150000, and the structural formula of the polycarboxylate superplasticizer is as follows: according to the invention, the esterification product of the unsaturated polyether monomer and the first compound is used for synthesis of the polycarboxylate water reducer, a benzene ring and a carboxyl structure are introduced at the tail end of a branched chain of a polycarboxylate water reducer molecule, the benzene ring structure enhances the steric hindrance effect of the branched chain of the polycarboxylate water reducer molecule, and the carboxyl structure enables the branched chain of the polycarboxylate water reducer molecule to have not only the steric hindrance effect but also the electrostatic repulsion effect, so that the prepared polycarboxylate water reducer has higher water reduction rate. |
