Normal-temperature synthesized concrete viscosity reducer and preparation method thereof
The invention discloses a normal-temperature synthesized concrete viscosity reducer and a preparation method thereof, and belongs to the technical field of building materials. The concrete viscosity reducer is prepared from the following components in percentage by mass: 60 to 75 percent of liquid polyether, 3 to 6 percent of unsaturated carboxylic acid monomer, 0.05 to 0.5 percent of unsaturated functional monomer, 0.1 to 0.5 percent of oxidizing agent, 0.03 to 0.2 percent of reducing agent, 0.05 to 0.3 percent of chain transfer agent, 1 to 3 percent of aqueous alkali and the balance of deionized water. The prepared viscosity reducer can obviously reduce the viscosity of a concrete mixture, can be synthesized at normal temperature, is low in production energy consumption and cost, can increase economic benefits, has the characteristic of low mixing amount, and can obviously reduce the emptying time of an inverted slump cone of high-strength concrete.
本发明公开了一种常温合成的混凝土降粘剂及其制备方法，属于建筑材料技术领域。该混凝土降粘剂，包括如下组分：按质量计，液体聚醚60‑75%，不饱和羧酸单体3‑6%，不饱和功能单体0.05‑0.5%，氧化剂0.1‑0.5%，还原剂0.03‑0.2%，链转移剂0.05‑0.3%，碱溶液1‑3%，其余为去离子水。本发明制备的降粘剂能够明显降低混凝土拌合物的粘度，并且可以在常温下合成，生产能耗成本低，可增加经济效益，还具有低掺量的特点，能够明显降低高强混凝土的倒置坍落度筒排空时间。
