Synthesis method and application of high-reactivity water reducing agent monomer
The invention relates to the technical field of water reducing agents, and discloses a synthesis method and application of a high-reaction-activity water reducing agent monomer, propargyl alcohol or butynediol is used as an alkynol monomer, ethylene oxide or propylene oxide is used as an epoxy monomer, a polyether intermediate is synthesized in the presence of an organic base catalyst, and the high-reaction-activity water reducing agent monomer is obtained. The novel polyether type high-reaction-activity water reducing agent monomer is further synthesized under the catalysis of alkali metal, the synthesis method is simple and efficient, and the activity of the monomer is high. In an initiation system adopting hydrogen peroxide and ammonium persulfate, the high-performance polyether polycarboxylic acid type water reducing agent is obtained through polymerization with an acrylic monomer, and the high-performance polyether polycarboxylic acid type water reducing agent is high in conversion rate, excellent in performance, excellent in dispersing capacity and good in flowability.
本发明涉及减水剂技术领域，且公开了高反应活性减水剂单体的合成方法和应用，以丙炔醇或丁炔二醇作为炔醇单体，环氧乙烷或环氧丙烷作为环氧单体，在有机碱催化剂下合成了聚醚中间体，进一步在碱金属催化下合成了新型聚醚型高反应活性减水剂单体，合成方法简单高效，单体的活性高。采用过氧化氢和过硫酸铵的引发体系中，与丙烯酸单体聚合得到高性能的聚醚聚羧酸型减水剂，转化率高，性能优异，具有优良的分散能力和良好的流动性。
