High-adaptability six-carbon polycarboxylic acid water reducer mother liquor and preparation method thereof
The invention discloses a high-adaptability six-carbon polycarboxylic acid water reducing agent mother liquor and a preparation method thereof, and belongs to the technical field of water reducing agents. Comprising a base material, an additive and a neutralizer, and after the additive is added into the base material to react, the neutralizer is added to prepare the polycarboxylate superplasticizer, the additive is prepared by dissolving acrylic acid and vitamin C in water; the neutralizer is prepared by dissolving sodium hydroxide in water; the backing material is prepared by dissolving a six-carbon macromonomer, sodium hypophosphite, hydrogen peroxide, ferrous sulfate and ammonium persulfate in water. The slump retaining agent has good slump retaining performance and water reducing performance, and is wide in application range and low in production energy consumption.
本发明公开了一种高适应性六碳聚羧酸减水剂母液及其制备方法，属于减水剂技术领域。包括底料、添加料和中和剂，所述添加料加入底料内反应完成后加入中和剂制成聚羧酸减水剂；所述添加料由丙烯酸和维生素C溶于水制成；所述中和剂由氢氧化钠溶于水制成；所述底料由六碳大单体、次磷酸钠、双氧水、硫酸亚铁和过硫酸铵溶于水制成。本发明具有良好的保坍性能与减水性能，且适用面宽、生产能耗低。
