Based on green chemistry and molecular design theory of concrete admixture, the process for the cleaner production of novel carboxylic grafted polymeric concrete slump retaining agent has been studied.
结果表明,以复合引发剂(K2S2O8+30%H2O2)替代BPO(过氧化苯甲酰)引发剂,以水替代有机溶剂,通过一釜多步串联反应,实现了混凝土保坍剂的清洁生产,彻底消除了传统反应性高分子生产工艺对环境的污染。
