| titleOfInvention | A kind of preparation method of high thixotropic Early-strength polycarboxylate superplasticizer |
| abstract | The invention discloses a kind of preparation methods of high thixotropic Early-strength polycarboxylate superplasticizer, include the following steps：(1) isobutene alcohol polyoxyethylene ether and/or prenol polyoxyethylene ether, small molecule polyethers, Unsaturatcd fatty acid glycerides, quaternary ammonium salt monomer and oxidant are added to the water, in 15~30 DEG C of stirrings to dissolving；(2) reducing agent and water are configured to the first solution, chain-transferring agent and water is configured to the second solution, unsaturated monocarboxylic acid, unsaturated carboxylate type monomer and water are configured to third solution；(3) above-mentioned first solution, the second solution and third solution are added dropwise in the material of step (1) in 3~4h simultaneously, after being added dropwise at 35~40 DEG C 1~1.5h of insulation reaction；(4) it after the material reaction of step (3) is complete, is added in alkaline conditioner and pH to 6~7 is to get the high thixotropic Early-strength polycarboxylate superplasticizer.Polycarboxylate water-reducer prepared by the present invention has excellent thixotropic property. |
