含膦基抗泥保坍型聚羧酸减水剂的合成及性能研究

Study on Synthesis and Properties of Phosphate-based Mud-resistant and Collapse-resistant Polycarboxylate

通过两步连续酯化的方法制备了含膦基聚羧酸减水剂,通过红外光谱对合成的含膦基聚羧酸减水剂的分子结构进行表征,并对其进行水泥净浆流动度、胶砂扩展度以及混凝土性能测试。

In this paper,a phosphine-containing polycarboxylic acid water reducer was prepared by two-step continuous esterification.The molecular structure of the synthesized phosphine-containing polycarboxylic acid water reducer was characterized by FT-IR spectrum and It performs cement paste flow,mortar expansion,and concrete performance testing.
