Slump-retaining water reducing agent mother liquor and preparation method thereof
The invention discloses a slump-retaining water reducer mother liquor and a preparation method thereof, and the slump-retaining water reducer comprises the following raw materials: alkylene alkenyl polyoxyethylene ether, hydrogen peroxide, an acrylate polymerization initiator mixture, an acrylate copolymerization initiation solution, a lipid-containing gel substance, a sodium hydroxide solution and deionized water. The lipid-containing gel substance can enhance the water-retaining property of the water reducer and reduce the water loss of concrete in the stirring and transportation processes, so that the stability of the concrete is improved, sedimentation and layering are prevented, the lipid-containing gel can react with free chloride ions in water to generate a water-insoluble gel substance, the permeability of the concrete is reduced, and the water-retaining property of the concrete is improved. The water reducing agent is favorable for improving the durability of concrete and reducing permeation of moisture and harmful chemical substances, so that the service life of the concrete is prolonged, the water reducing efficiency of the water reducing agent is improved, good workability of the concrete is allowed to be kept under the condition of lower dosage, meanwhile, the flowability and plasticity of the concrete are improved, and pouring and forming are facilitated.
本发明公开了一种保坍型减水剂母液及其制备方法，所述保坍型减水剂由以下原料组成：烷撑烯基聚氧乙烯醚、双氧水、丙烯酸酯聚合引发剂混合物、丙烯酸酯共聚引发溶液、含脂类凝胶物质、氢氧化钠溶液和去离子水，含脂类凝胶物质能够增强减水剂的保水性，减少混凝土在搅拌和运输过程中的水分流失，进而改善混凝土的稳定性，防止沉降和分层，含脂类凝胶能够与水中的游离氯离子反应，生成不溶于水的凝胶物质，降低混凝土的渗透性，有助于提高混凝土的耐久性，减少水分和有害化学物质的渗透，从而延长混凝土的使用寿命，提高减水剂的减水效率，允许在较低用量下保持混凝土的良好工作性，同时改善其流动性和可塑性，便于浇筑和成型。
