Concrete water-retaining agent and preparation method thereof
The invention discloses a concrete water-retaining agent and a preparation method thereof. The concrete water-retaining agent is prepared from the following raw materials in parts by weight: 2 to 10 parts of hydroxypropyl methyl cellulose, 1 to 10 parts of sodium hydroxide, 8 to 15 parts of diethylisopropanolamine, 8 to 15 parts of triethanolamine, 2 to 10 parts of amylopectin, 1 to 5 parts of molasses, 1 to 5 parts of COPS-1, 5 to 10 parts of sodium pyrosulfite, 5 to 15 parts of ethylene glycol, 5 to 15 parts of mud-resistant polycarboxylate superplasticizer, 1 to 10 parts of sodium thiocyanate, 5 to 10 parts of isopentenol polyoxyethylene ether, 1 to 5 parts of cyclodextrine, 1 to 5 parts of melamine, 1-5 parts of maltodextrin, 3-10 parts of glycerol, 1-5 parts of polyacrylamide, 0.1-2 parts of a de-foaming agent, 0.1-2 parts of a preservative and 836-950 parts of de-ionized water. The water-retaining agent provided by the invention has a nano fine fiber component, and can be effectively inserted into hydrated minerals of cement and other rubber materials, so that the utilization rate of the cement and other rubber materials is improved, the dispersity of cement particles is quickly improved, and the efficacy of a concrete high-efficiency water reducing agent is improved.
本发明公开一种混凝土保水剂及其制备方法，该混凝土保水剂包括原料重量份数如下：羟丙基甲基纤维素2～10份、氢氧化钠1～10份、二乙异丙醇胺8～15份、三乙醇胺8～15份、支链淀粉2～10份、糖蜜1～5份、COPS‑1 1～5份、焦亚硫酸钠5～10份、乙二醇5～15份、抗泥型聚羧酸减水剂5～15份、硫氰酸钠1～10份、异戊烯醇聚氧乙烯醚5～10份、环状糊精1～5份、三聚氰胺1～5份、麦芽糊精1～5份、丙三醇3～10份、聚丙烯酰胺1～5份、消泡剂0.1～2份、防腐剂0.1～2份、去离子水836～950份。本发明所提出的保水剂具有纳米微细纤维组分，能有效插入水泥等胶材的水化矿物中，提高水泥等胶材的利用率，快速提高水泥颗粒的分散性，提升混凝土高效减水剂的功效。
