Halogen ion-free phosphate water reducing agent and preparation method and application thereof
The invention discloses a halogen ion-free phosphate water reducing agent and a preparation method and application thereof. The halogen ion-free phosphate water reducing agent comprises a phosphate group-containing multi-branched macromolecule and water, wherein the phosphate group-containing multi-branched macromolecule takes organic amine as a main chain and takes a plurality of grafted phosphorous acid adsorbing groups and polyether side chains as side chains. The halogen ion-free phosphate water reducing agent is convenient to adjust in structure, simple in preparation process and excellent in slump loss resistance and clay tolerance.
本发明公开了一种不含卤素离子的膦酸基减水剂及其制备方法和应用，所述不含卤素离子的膦酸基减水剂的组成包括一种含膦酸基团的多支化大分子和水，所述含膦酸基团的多支化大分子以有机胺为主链，侧链为接枝的若干亚磷酸吸附基团和聚醚侧链。所述不含卤素离子的膦酸基减水剂结构调整方便，制备过程简单，保坍和粘土耐受性优异。
