Preparation method of anti-mud slow-release polycarboxylate water reducer
The invention discloses a preparation method of an anti-mud slow-release polycarboxylate water reducer. Acrylic acid, hydroxyethyl acrylate, 2-hydroxyethyl methacrylate phosphate and isopentenol polyoxyethylene ether are used as reaction monomers, hydrogen peroxide/ascorbic acid is used as an initiator, mercaptopropionic acid is used as a chain transfer agent, and the novel anti-mud slow-release polycarboxylic acid water reducer is synthesized through free radical copolymerization reaction. Compared with a common polycarboxylic acid water reducer, the water reducer has low sensitivity to montmorillonite and has a good slow release function.
本申请公开了一种抗泥缓释型聚羧酸减水剂的制备方法；以丙烯酸、丙烯酸羟乙酯、2‑羟乙基甲基丙烯酸酯磷酸酯、异戊烯醇聚氧乙烯醚为反应单体，过氧化氢/抗坏血酸为引发剂，巯基丙酸为链转移剂，通过自由基共聚合反应合成了一种新型的抗泥缓释型聚羧酸减水剂，该减水剂与普通聚羧酸减水剂相比，对蒙脱土的敏感性低，且具有很好的缓释功能。
