| 摘 要： | 以丙烯酸、甲氧基聚乙二醇丙烯酸酯、烯丙基磺酸钠为原料,分别制备引入羧基侧链、引入聚氧乙烯侧链以及同时引入羧基与聚氧乙烯侧链的聚羧酸减水剂.加入水泥净浆性能测试结果表明,羧基侧链对减水剂的分散性能影响较大,聚氧乙烯侧链对减水剂的保塑性能影响较大,同时具有两种侧链的减水剂的分散性能和保塑性能都得到提高.

| Abstract: | Three kinds of polycarboxylate superplasticizers which molecules only containing carboxyl group(CG) or polyoxyethylene side chain(PSC),and possessing such both groups,have been successfully synthesized using acrylic acid and methoxy polyethylene glycol acrylate as well as sodium allyl sulfonate as the starting materials.The properties of the as-prepared polycarboxylate superplasticizers were investigated by adding it in cement paste.The performance showed that the carboxyl group greatly influences the dispe... |
