不同分子结构的聚羧酸减水剂对水泥分散性能的影响综述

Effect of different molecular structure of polycarboxylate superplasticizer on the dispersion properties of cement

文章通过分析聚羧酸减水剂的主链、侧链、官能团等介绍了聚羧酸减水剂的分子结构。同时对比发现:不同大单体、主链长度、侧链密度、侧链长度的聚羧酸减水剂,其对水泥的分散能力不尽相同。向聚羧酸减水剂分子中引入不同的官能团对水泥流动性的影响效果也不同。

In this paper, the molecular structure of the polymer was introduced through the analysis of the main chain, side chain and functional groups of the polymer. By comparison, different macromonomer, the density of side chain, the length of side chain and the length of main chain of polycarboxylate superplasticizer, the cement dispersion force are different. When introducing different functional groups, the effect on the cement fl uidity is also different.
