Phosphate type polyether monomer and preparation method thereof
The invention provides a phosphate type polyether monomer and a preparation method thereof. The novel phosphate type polyether monomer developed by the invention is prepared by the following steps: carrying out alkoxylation polymerization on an amine substance to generate amino polyether, and reacting the amino polyether with a phosphorylation reagent. The cement dispersant has a certain cement dispersant function, has a certain improvement space on cement fluidity under the condition of mixing with cement and water, can be directly used for synthesis of a polycarboxylic acid water reducer, has special performances of good concrete workability, good dispersion retention capability, applicability under a low water/cement ratio and the like, and is widely concerned by the industry.
本申请提供一种磷酸酯型聚醚单体及其制备方法。本发明开发的新型磷酸酯型聚醚单体由胺类物质进行烷氧基化聚合后生成的胺基聚醚，再与磷酸化试剂反应而制得。具有一定的水泥分散剂功能，在与水泥、水混合的条件下对水泥流动度有一定的提升空间，也可以直接用于聚羧酸减水剂的合成，混凝土和易性好，分散保持能力良好以及可以在低水/灰比下适用等特殊性能，受到业界的广泛关注。
