Viscosity reduction type ester ether copolymerized polycarboxylic acid water reducer and normal-temperature preparation method thereof
The invention specifically discloses a viscosity reduction type ester ether copolymerized polycarboxylic acid water reducer. The water reducer comprises vinyl polyoxyethylene ether, isopentenyl polyoxyethylene ether, ethyl methacrylate, n-butyl methacrylate, isobornyl methacrylate, isooctyl methacrylate, octylphenol polyoxyethylene ether OP-4, octylphenol polyoxyethylene ether OP-10, sodium dodecyl diphenyl ether disulfonate, glucose, soluble corn starch, vitamin C, acrylic acid, mercaptoethanol, hydrogen peroxide, ammonium persulfate and water. The invention also provides a normal-temperature preparation method of the viscosity reduction type ester ether copolymerized polycarboxylic acid water reducer. According to the invention, the polycarboxylic acid water reducer is prepared at normal temperature, so that the later application performance of the polycarboxylic acid water reducer can be obviously improved while the higher conversion rate of the water reducer monomer is ensured, the manufacturing cost is greatly saved, the profit rate of the product is increased, and the industrial value is very good.
本发明具体公开了一种降粘型酯醚共聚聚羧酸减水剂，包括乙烯基聚氧乙烯醚、异戊烯基聚氧乙烯醚、甲基丙烯酸乙酯、甲基丙烯酸正丁酯、甲基丙烯酸异冰片酯、甲基丙烯酸异辛酯、辛基酚聚氧乙烯醚OP‑4、辛基酚聚氧乙烯醚OP‑10、十二烷基二苯醚二磺酸钠、葡萄糖、可溶性玉米淀粉、维生素C、丙烯酸、疏基乙醇、双氧水、过硫酸铵和水。本发明还提供了一种降粘型酯醚共聚聚羧酸减水剂常温制备方法。本发明通过在常温下制备聚羧酸减水剂，在保证了减水剂单体获得较高转化率的同时，并能够明显提高其后期应用性能，大大节省了制造成本，增加了产品的利润率，具有很好的工业价值。
