Modified polyether water reducer as well as preparation method and application thereof
The invention belongs to the technical field of building materials, and particularly relates to a modified polyether water reducer as well as a preparation method and application thereof. The modified polyether water reducer is prepared from the following raw materials: ethylene oxide-propylene oxide block polyether, unsaturated polyoxyethylene ether, acrylic acid, methacrylic acid-beta-hydroxyethyl phosphate and maleic anhydride. The modified polyether water reducer has the characteristics of high water reducing rate, good viscosity reducing effect and the like, can obviously prolong the rewinding time of the expansion degree of UHPC when being applied to a UHPC system, does not influence the later strength of the UHPC, and does not involve high-temperature and high-pressure reactions in the preparation process.
本发明属于建筑材料技术领域技术领域，具体涉及一种改性聚醚减水剂及其制备方法与应用。该改性聚醚减水剂的制备原料包括：环氧乙烷环氧丙烷嵌段聚醚、不饱和聚氧乙烯基醚、丙烯酸、甲基丙烯酸‑β‑羟乙酯磷酸酯和马来酸酐。该改性聚醚减水剂具有减水率高、降粘效果好等特性，应用在UHPC体系能够明显提高UHPC的扩展度的倒筒时间，且不影响UHPC的后期强度，同时制备过程中不涉及高温、高压反应。
