Retarding type high-efficiency water reducing agent and preparation method thereof
The invention discloses a retarding type high-efficiency water reducing agent which is obtained by compounding a sulfonate water reducing agent with a polyfunctional group water reducing agent, the polyfunctional group water reducing agent is a copolymer in which carboxylic acid participates, and at least comprises molecular structures of at least two functional groups of caprolactam, adamantyl ester and long-chain oxyvinyl phosphate. The retarding type high-efficiency water reducing agent prepared by the invention not only has an excellent water reducing effect, but also can obviously delay the concrete setting time, and can keep stable performance in different environments, so that the workability and durability of concrete are effectively improved, and the requirements of the modern building industry on high-performance concrete materials are met.
本发明公开了一种缓凝型高效减水剂，其由磺酸盐类减水剂复配多官能团减水剂得到；所述多官能团减水剂为羧酸参与的共聚物，且至少包括己内酰胺、金刚烷酯、长链氧乙烯基磷酸酯中的至少两个官能团分子结构。本发明制备得到的缓凝型高效减水剂，既具有优异减水效果，又能显著延缓混凝土凝结时间，且在不同环境下都能保持稳定性能的高效减水剂，从而有效提升混凝土的工作性和耐久性，满足现代建筑行业对高性能混凝土材料的需求。
