Water-reducing slump-retaining comprehensive polycarboxylic acid water reducer and preparation method thereof
The invention discloses a water-reducing slump-retaining comprehensive polycarboxylic acid water reducer and a preparation method thereof. The water reducer comprises an unsaturated polyether macromonomer, an unsaturated carboxylic acid monomer and a functional ester monomer, wherein a molar ratio of the unsaturated polyether macromonomer to the unsaturated carboxylic acid monomer to the functional ester monomer is 1: (0.5-3.5): (0.1-2), and the functional ester monomer comprises at least one selected from maleic anhydride-2, 2-dimethyl cyclohexanol diester, maleic anhydride-2, 2-dimethyl butanediol, maleic anhydride-dimethyl-1-octanol diester, maleic anhydride-2-decanol diester, acrylic acid-2-butyl-2-ethyl-1, 3-propanediol diester, methacrylic acid-ethylene glycol diester and methacrylic acid-propylene glycol diester. The water-reducing slump-retaining comprehensive polycarboxylic acid water reducer can effectively solve the problem of sensitive effect of the existing water reducing agent.
本发明公开了一种减水保坍综合型聚羧酸减水剂及其制备方法，减水剂包括不饱和聚醚大单体、不饱和羧酸单体和功能酯单体，不饱和聚醚大单体、不饱和羧酸单体和功能酯单体的摩尔比为1:0.5‑3.5:0.1‑2；功能酯单体包括马来酸酐‑2,2‑二甲基环己醇双酯、马来酸酐‑2,2‑二甲基丁双醇、马来酸酐‑二甲基‑1‑辛醇双酯、马来酸酐‑2‑癸醇双酯、丙烯酸‑2‑丁基‑2‑乙基‑1,3‑丙二醇双酯、甲基丙烯酸‑乙二醇双酯和甲基丙烯酸‑丙二醇双酯中的至少一种。该减水保坍综合型聚羧酸剂可有效解决现有减水剂存在的效果敏感的问题。
