摘要
用甲基丙烯酸甲酯,丙烯酸,丙烯酸异辛酯等单体通过共聚反应可制备一种聚羧酸高效减水剂,该减水剂 具有掺量低、减水率高,对混凝土有较好的增强效果等特点。
A polycarboxylic acid HRWAR can be prepared by copolymerization. It is combined with some monomers such as methyl metharcrylate, acrylic acid and acrylic thioglycolate. This kind of water - reducer has the following features: fewer adding quantities, higher water - reducing ratio, better strengthening to concrete, etc .
