Wet-mixed mortar admixture as well as preparation method and application thereof
The invention provides a wet-mixed mortar admixture. The wet-mixed mortar admixture comprises the following components in parts by mass: 10-20 parts of end group functionalized polycarboxylic acid, 10-20 parts of a polyether viscosity modifier, 1-5 parts of a thickening agent, 5-10 parts of a retarder, 0.5-2 parts of an air entraining agent, 1-5 parts of a reinforcing agent, 0.1-0.5 part of a dispersing agent and 60-80 parts of water. The end group functionalized polycarboxylic acid and the dispersing agent are synthesized and compounded with other raw materials, and the wet-mixed mortar admixture can improve the fluidity and separation resistance of mortar, so that the wet-mixed mortar admixture has excellent working performance and mortar strength.
本发明提供种湿拌砂浆外加剂，包含以下质量份数的组分：端基功能化聚羧酸10～20份、聚醚类粘度调节剂10～20份、增稠剂1～5份、缓凝剂5～10份、引气剂0.5～2份、增强剂1～5份、分散剂0.1～0.5份、水60～80份。本发明通过对端基功能化聚羧酸、分散剂进行合成，并与其他原料进行复配，该湿拌砂浆外加剂能够提高砂浆的流动性、抗分离性，使其具有优异的工作性能和砂浆强度。
