摘要
甲基丙烯酸(MAA)和聚乙二醇单甲醚(MPEG)1200的酯化,再与磺酸类单体和丙烯酰胺发生聚合反应,从而生成了具有缓凝作用的聚羧酸。探讨了在原有聚羧酸减水剂合成中加入不同量的丙烯酰胺后的净浆流动度、凝结时间、坍落度、抗压强度等指标的影响。
The methyl acrylic acid（MAA）and the polyethylene glycol single methyl ether（MPEG）1200 esterifications,again has the polyreaction with the sulfonic acids monomer and the acrylic amide,thus produced had the retardation to gather the carboxylic acid.Here we have mainly discussed after original gathers in the carboxylic acid water reducing agent synthesis not to join commensurability target the only and so on acrylic amide thick liquid mobility,set time,slump,compressive strength influences.
