聚羧酸高效减水剂的合成及性能研究

Preparation and properties of the polycarboxylic superplasticzer

本文主要研究以烯丙醇聚氧乙烯醚、丙烯酸、马来酸酐和甲基丙烯磺酸钠为主要原料的聚羧酸减水剂的制备,并与传统萘系减水剂进行性能测试比较。结果表明,自制聚羧酸减水剂具有减水率高、流动度损失小、抗压强度比高等优点。

Study was focused on preparation technology of the polycarboxylic superplasticzer series with allyl alcohol polyxyethylene,acrylic acid,maleic anhudride and sodium metyl acrylamide as the main raw material.Test was made on properties of the reducer.The result shows this water reducer features in high water reducing rate,long keeping time of slump and high ratio of resistanc press.
