Concrete viscosity modifier and preparation method thereof
The invention discloses a concrete viscosity modifier and a preparation method thereof. The concrete viscosity modifier is prepared from the following main raw materials in parts by weight: 0.1 to 8 parts of amylopectin, 1 to 8 parts of butanediol, 1 to 12 parts of dipropylene glycol dimethyl ether, 10 to 40 parts of welan gum, 10 to 20 parts of cyclodextrine, 0.2 to 0.8 part of sodium polyacrylate, 0.1 to 0.5 part of carbamide, 0.1 to 10 parts of sodium hydroxide and 900.7 to 977.5 parts of deionized water. The viscosity modifier provided by the invention is simple in synthesis process, can be synthesized at normal temperature, is low in energy consumption, is prepared from easily available and harmless raw materials, is green and environment-friendly, and is suitable for industrial production; and the viscosity modifier can solve the concrete state problem caused by fault gradation of machine-made sand, improve the wrapping property and workability of concrete, and improve the pumpability of the concrete.
本发明公开一种混凝土粘度改性剂及其制备方法，该粘度改性剂包括：原料主要成分及重量份数如下：支链淀粉0.1～8份、丁二醇1～8份、二丙二醇二甲醚1～12份、温伦胶10～40份、环状糊精10～20份、聚丙烯酸钠0.2～0.8份、碳酰胺0.1～0.5份、氢氧化钠0.1～10份、去离子水900.7～977.5份。本发明提出的粘度改性剂合成工艺简单，常温即可合成，能耗低，原料易得无害，绿色环保，适于工业生产；粘度改性剂可以解决机制砂断级配造成的混凝土状态问题，提高混凝土的包裹性，和易性，可以提高混凝土的泵送性。
