| titleOfInvention | Shrinkage-reducing polycarboxylate superplasticizer and preparation method thereof |
| abstract | The invention relates to the technical field of building additives, in particular to a reduction type polycarboxylate superplasticizer and a preparation method thereof. The water reducing agent comprises: esterification products, unsaturated polyoxyethylene ether, an emulsifier, an initiator solution, a chain transfer agent solution, an ester macromonomer, acrylic acid, a shrinkage reducing functional monomer and unsaturated sulfonate mixed solution. The preparation method comprises the steps of preparing an esterification product; carrying out copolymerization reaction; carrying out neutralization reaction; the esterification product is prepared by esterifying the coconut diethanolamide and the unsaturated acid, and has the advantages of low cost and simple and convenient operation, and the prepared esterification product is subjected to copolymerization reaction with the shrinkage reducing functional monomer, so that the main chain of the polycarboxylate superplasticizer has hydrophilic groups such as amide and the like and shrinkage reducing groups. |
