| titleOfInvention | A kind of method of normal temperature synthesis polycarboxylate water-reducer |
| abstract | The invention discloses a kind of method of normal temperature synthesis polycarboxylate water-reducer, preparation method comprises the following steps:1) under normal temperature, unsaturated APEO and water are added into reactor stirring；2) while A liquid and B liquid is added dropwise, A liquid is unsaturated carboxylic acid or acid anhydrides, the mixed aqueous solution of reducing agent and chain-transferring agent, and time for adding is 3 3.5h, and B liquid is aqueous oxidizing agent solution, and time for adding is 2 2.5h；3) curing 1h is dripped, adds sodium hydroxide solution, adjustment pH value to 57.The polycarboxylate water-reducer of the present invention is obtained using water as solvent by radical polymerization at normal temperatures.Whole building-up process saves the energy, reduces pollution, and water-reducing property is better than domestic and international product, can widely apply in the industrial production without heating. |
