Fluorine-containing hyperbranched polymer viscosity reducer as well as preparation method and application thereof
The invention belongs to the technical field of concrete additives, and particularly relates to a fluorine-containing hyperbranched polymer viscosity reducer as well as a preparation method and application thereof. Fluorine-containing acrylate reacts with diethanol amine to synthesize a monomer, glycerol is used as a core molecule, and the core molecule reacts with the monomer to obtain the hyperbranched polymer. A fluorine element is introduced into a monomer, then a hyperbranched polymer is synthesized, and the prepared macromolecular structure is used for the concrete viscosity reducer and can achieve a good viscosity reduction effect.
本发明属于混凝土添加剂技术领域，具体涉及一种含氟超支化聚合物降粘剂及其制备方法和应用。含氟丙烯酸酯和二乙醇胺反应合成单体，丙三醇为核分子，核分子与单体反应得到超支化聚合物。在单体中引入氟元素，然后合成超支化聚合物，制备得到的大分子结构，用于混凝土降粘剂，能获得好的降粘效果。
