titleOfInvention | A kind of low-sensitivity water reducing agent and preparation method thereof |
abstract | The invention relates to the technical field of concrete admixtures, in particular to a low-sensitivity water-reducing agent and a preparation method thereof, wherein the low-sensitivity water-reducing agent comprises the following preparation components: EPEG, unsaturated carboxylic acid small monomers , oxidizing agent, reducing agent, molecular weight regulator and silane coupling agent modified layered calcium aluminum double metal hydroxide. In the low-sensitivity water-reducing agent provided by the invention, the CaAl-LDH nanosheets with a large amount of positive charges are cross-linked with the low-sensitivity polycarboxylic acid through a silane coupling agent, so that the prepared polycarboxylate water-reducing agent has The larger adsorption area on the cement surface improves the water-reducing effect of the water-reducing agent, and at the same time, the molecular size increases, which prevents the polycarboxylic acid from being adsorbed by the mud with an intercalated structure, improves the adaptability to the cement, and reduces the content of the mud. Sensitivity to change, with broad market application prospects. |
