Super-early-strength tackifier and preparation method thereof
The invention discloses a super-early-strength tackifier and a preparation method thereof, and belongs to the technical field of building materials. The tackifier is prepared from the following raw materials: lithium carbonate, potassium carbonate, hydroxypropyl methyl cellulose, polyacrylamide and mixed water; the preparation method comprises the following steps: after selecting raw materials of the tackifier, weighing the following materials in parts by weight: 1 to 40 parts of lithium carbonate, 10 to 30 parts of potassium carbonate, 0.5 to 4 parts of hydroxypropyl methyl cellulose, 1 to 4 parts of polyacrylamide and 30 to 80 parts of mixed water; adding a tackifier raw material into the reaction kettle and stirring; and after the stirring is completed, obtaining a finished product. The springback of surrounding rock sprayed concrete is effectively reduced, the time for removing the formwork of the concrete is shortened, the turnover rate of the concrete formwork is increased, the construction progress is accelerated, the construction cost is saved, and good social and economic benefits are achieved.
一种超早强增粘剂及其制备方法，属于建筑材料技术领域。增粘剂原材料选取：碳酸锂、碳酸钾、羟丙基甲基纤维素、聚丙烯酰胺、混合用水；对增粘剂原材料选取后，按照材料重量份进行称取碳酸锂、碳酸钾、羟丙基甲基纤维素、聚丙烯酰胺、混合用水，其中各材料用量分别为碳酸锂1份～40份、碳酸钾10份～30份、羟丙基甲基纤维素0.5份～4份、聚丙烯酰胺1份～4份、混合用水30份～80份；将增粘剂原材料加入反应釜中搅拌；搅拌搅拌完成后，即得到成品。有效降低围岩喷射混凝土回弹，缩短混凝土可拆模时间，提高混凝土模板周转率，加快施工进度，节省工程造价，具有良好的社会经济效益。
