Abstract

本发明公开了一种规整序列结构的聚羧酸减水剂的制备方法。本发明所述制备方法包括：将丙烯酸聚乙二醇醚酯大单体A和含氨基的羧酸B进行迈克尔加成反应，反应5～12h后，之后降温至0℃，缓慢匀速滴加丙烯酰氯，滴加结束后，在常温条件下继续反应12h，即得到含羧基的聚醚大单体C；将含羧基的聚醚大单体C、小分子RAFT试剂、引发剂和水充分混合，保持聚合质量浓度30～60％，在N 2气氛下，升温至60～80℃，反应2～5h后即得规整序列结构的聚羧酸减水剂。本发明制得的聚羧酸减水剂适用于砂石骨料含泥量高的地区，并且具有低掺量、高减水和高保坍的优点；本发明的制备工艺简单，生产过程绿色环保、成本低。
