    The invention provides a polycarboxylic acid super-retarding water reducing agent and a preparation method thereof, and belongs to the technical field of water reducing agents. Unsaturated polyether, polyhydroxy acid, unsaturated acid, hydroxypropyl methyl cellulose, sodium citrate, an initiator, sulfuric acid, lauryl mercaptan and water are adopted as raw materials, and the water reducer is obtained through esterification and polymerization. The water reducer disclosed by the invention has a good water retention effect, enhances a retarding effect, and also increases the mechanical strength of cement.

    本发明提供了一种聚羧酸超缓凝减水剂及其制备方法，属于减水剂技术领域。本发明采用不饱和聚醚，多羟基酸、不饱和酸、羟丙基甲基纤维素、柠檬酸钠、引发剂、硫酸、十二烷基硫醇和水为原料，经酯化和聚合，得到减水剂。本发明的减水剂保水效果好，加强缓凝效果，同时增加水泥的机械强度。
