Preparation method for synthesizing high-slump-retaining water reducing agent by adopting six-carbon monomer
The invention relates to the technical field of preparation methods of water reducing agents, and discloses a preparation method for synthesizing a high slump loss resistant water reducing agent by adopting a six-carbon monomer, which comprises the following steps: taking materials, proportioning a monomer solution, preparing a dropwise adding solution, dropwise adding and preserving heat, and adjusting the pH value. The six-carbon monomer ethylene glycol vinyl ether polyoxyethylene ether is used as a main raw material, the structure is novel, the design is reasonable, and the designed and synthesized polycarboxylate superplasticizer has water reducing and slump retaining functions, is wide in adaptability and can adapt to various coarse and fine aggregates. Meanwhile, the problems that an existing polycarboxylate superplasticizer is sensitive to artificial sand and large in mixing amount fluctuation are solved.
本发明涉及减水剂制备方法的技术领域，公开了一种采用六碳单体合成高保坍减水剂的制备方法，包括取料、配比单体溶液、制备滴加溶液、滴加保温、调节酸碱度；本发明提供的以六碳单体乙二醇乙烯基醚聚氧乙烯醚为主要原料并结构新颖，设计合理，设计合成的聚羧酸减水剂兼有减水和保坍功能，适应性广泛，可适应各种粗细骨料。同时，克服了现有聚羧酸减水剂对人工砂敏感，掺量波动大的问题。
