Copolymer water reducing agent for fabricated building components and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to a copolymer water reducing agent for fabricated building components and a preparation method thereof. The copolymer water reducing agent is obtained by taking aryl vinyl phenol polyoxyethylene ether and allyl-terminated polyethylene glycol as macromonomers and taking acrylic acid, acrylamide and sodiummethallyl sulfonate micromonomers to be subjected to free radical copolymerization in an aqueous solution system. Through molecular design and process optimization, the ultra-high performance copolymer water reducing agent is researched and developed, and the comprehensive performance requirements of high thixotropy, high expansibility and ultra-early strength performance of fabricated building components are met.
本发明属于建筑材料技术领域，更具体的涉及一种装配式建筑部件用共聚物减水剂及其制备方法；所述共聚物减水剂以芳基乙烯基苯酚聚氧乙烯醚和丙烯基封端的聚乙二醇为大单体，以丙烯酸、丙烯酰胺和甲基丙烯磺酸钠小单体在水溶液体系下通过自由基共聚所得。本发明通过分子设计和工艺优化，研发出超高性能共聚物减水剂，满足装配式建筑部件高触变性、高扩展性、超早强性能的综合性能要求。
