以异戊烯醇聚氧乙烯醚(TPEG)、丙烯酸(AA)和丙烯酸羟乙酯(HEA)为单体,以氧化剂双氧水(DE)、还原剂吊白块作为氧化还原体系,在链转移剂的作用下,直接聚合制得羧酸类接枝共聚物保坍剂,并对该保坍剂进行了减水率、保坍性能测试,经混凝土实验证明,它具有一定减水效果和较好的保坍性能,与聚羧酸减水剂复合使用时,混凝土保坍性能优异。 The oxidative hydrogen peroxide (DE) and reductant were used as redox system in the monomer of isoprenol polyoxyethylene ether (TPEG), acrylic acid (AA) and hydroxyethyl acrylate (HEA) , The graft polymerization agent of carboxylic acid graft copolymer was prepared by direct polymerization, and the water-reducing rate and slump-proof performance of the preservative were tested. The concrete experiment proved that it has a good water-reducing effect and better Of the slump performance, and polycarboxylate superplasticizer compound, slump performance of concrete is excellent.
