Viscosity reduction type water reducing agent and preparation method thereof
A viscosity reduction type water reducing agent is prepared from, by weight, 25-45 parts of a monomer A, 3-5 parts of a monomer B, 2-4 parts of a monomer C, 0.1-0.3 part of a chain transfer agent, 0.4-1 part of an initiator and 50-60 parts of water. The monomer A is any one or more of methyl allyl polyoxyethylene ether, isobutene alcohol polyoxyethylene ether, hydroxybutyl vinyl polyethylene glycol ether, ethoxy vinyl polyethylene glycol ether and allyl polyethylene glycol ether; the monomer B is any one or more of acrylic acid, maleic acid and itaconic acid; the monomer C is any one or more of methacryloyloxyethyl phosphate, di(methacryloyloxyethyl) hydrogen phosphate and hydroxyethyl methacrylate; the initiator is a composition of an oxidation component and a reduction component; and thechain transfer agent is any one or more of mercaptopropionic acid, mercaptoacetic acid and mercaptoethanol. The water reducing agent releases free water to the maximum extent by reducing combinationwith water, increases the water-binder ratio, and is remarkable in viscosity reducing effect and wide in adaptability.
一种降粘型减水剂，包括如下重量份组分：25‑45份单体A、3‑5份单体B、2‑4份单体C、0.1‑0.3份链转移剂、0.4‑1份引发剂、50‑60份水，所述单体A为甲基烯基聚氧乙烯醚、异丁烯醇聚氧乙烯醚、羟丁基乙烯基聚乙二醇醚、乙氧基乙烯基聚乙二醇醚、烯丙基聚乙二醇醚中的任一种或几种，所述单体B为丙烯酸、马来酸、衣康酸中的任一种或几种，所述单体C为甲基丙烯酰氧乙基磷酸酯、磷酸氢二(甲基丙烯酰氧乙基)酯、甲基丙烯酸羟乙酯中的任一种或几种，所述引发剂为氧化组分和还原组分的组合物，所述链转移剂为巯基丙酸、巯基乙酸、巯基乙醇的任一种或几种。本发明减水剂通过降低与水结合，最大限度的释放自由水，增加水胶比，降粘效果显著，适应性广。
