Additive for wet-mixed mortar and preparation method thereof
The invention relates to the technical field of mortar admixtures, and discloses an admixture for wet-mixed mortar, which is composed of a polycarboxylic acid water reducer, an air entraining component, a thickening and water retention component, a retarding component and water. The retarding component is a micromolecular retarder, and the polycarboxylate superplasticizer is prepared from methyl allyl polyoxyethylene ether, a block PEG active macromonomer and acrylic acid through a reaction. The polycarboxylate superplasticizer in the admixture prepared by the invention is prepared by reacting methyl allyl polyoxyethylene ether, a block PEG active macromonomer and acrylic acid, and the retarding component is a micromolecular retarder; the wet-mixed mortar admixture with excellent performance can be prepared, so that the wet-mixed mortar has excellent workability retention time, excellent water-retaining property and good apparent density retentivity, thereby well solving the defects of overhigh volume weight and large consistency loss of a mortar mixture, having better applicability, and being worthy of popularization and application. And the construction requirements of various wet-mixed mortars can be met.
本发明涉及砂浆外加剂技术领域，公开了一种湿拌砂浆用外加剂，由聚羧酸减水剂、引气组分、增稠保水组分、缓凝组分以及水组成；所述缓凝组分为小分子缓凝剂，所述聚羧酸减水剂由甲基烯丙基聚氧乙烯醚、嵌段PEG活性大单体以及丙烯酸反应制得。本发明制备的外加剂中的聚羧酸减水剂由甲基烯丙基聚氧乙烯醚、嵌段PEG活性大单体以及丙烯酸反应制得，缓凝组分为小分子缓凝剂；可以配制出性能优异的湿拌砂浆外加剂，使湿拌砂浆具有优异的工作性保持时间，优异的保水性及良好的表观密度保持性，从而很好地解决了砂浆拌合物容重过高及稠度损失大的缺点，具有更好的适用性，可以满足各种湿拌砂浆的施工要求。
