| description | The invention belongs to the technical field of superplasticizers and preparation thereof, and provides a super early strength polycarboxylate superplasticizer and a preparation method thereof. The super early strength polycarboxylate superplasticizer is prepared by mixing isopentenol polyoxyethylene ether, super-early-strength functional monomer ester, acrylic acid, acrylamide, a chain transfer agent, a hydrogen peroxide solution, ascorbic acid and a sodium hydroxide solution. The super early strength functional monomer ester is introduced into the formula system, so that the early strength of concrete can be improved; early strength groups in the polycarboxylate superplasticizer can adsorb a large amount of water through hydrogen bonds in a cement system to form an adsorption hydration film, so that agglomeration of cement particles is effectively prevented, the content of fine particles in cement paste is increased, the water loss is effectively reduced, and the strength of concrete is remarkably improved. |
