| titleOfInvention | Preparation method of ether ester copolymerization type polycarboxylate superplasticizer with improved rheological property |
| abstract | The invention discloses a preparation method of an ether ester copolymerization type polycarboxylate water reducer with improved rheological property, which comprises the following raw materials of a first mixture, unsaturated polyether with the molecular weight of 4000-6000, unsaturated acid, a compound A, an initiator, a molecular weight regulator and deionized water through copolymerization, wherein the first mixture is prepared by carrying out ester exchange reaction on raw materials comprising methoxy polyethylene glycol with the molecular weight of 1000-4000, alkylphenol ethoxylates, unsaturated carboxylic ester and a polymerization inhibitor. The benzene ring and imide structures are introduced, and the introduction of the benzene ring structure can effectively improve the adsorption efficiency and the thickness of an adsorption layer of polymer molecules on the surface of cement particles, so that the space stabilization effect of the water reducing agent is more obvious; in the imide structure, the adsorption on the surface of cement particles can be improved, the electrostatic repulsion action among the cement particles is improved, and the stability and the fluidity of cement paste are improved. |
