Water-based polyhydroxy copolymer and application thereof in cement grinding aid
The invention discloses a water-based polyhydroxy copolymer. A preparation method of the water-based polyhydroxy copolymer comprises the following steps: dissolving triethanolamine oleic soap, allyl succinimide carbonate, eugenol rutinoside and bis (trimethylsilyl) vinyl phosphate in a high-boiling-point solvent to form a solution, adding an initiator into the solution, putting the solution in a microwave oven, carrying out microwave polymerization reaction in a nitrogen or inert gas atmosphere for 10-15 minutes, taking out the product after the reaction, pouring the product into acetone to precipitate the polymer, carrying out vacuum filtration, and drying the product in a vacuum drying oven at 60-70 DEG C for 10-15 hours, thereby obtaining the polyhydroxy copolymer. The cement grinding aid prepared from the polyhydroxy copolymer has the advantages of low production cost, low doping amount, obvious grinding aid enhancement effect and high use safety, can effectively improve the lubricating property and other properties of cement and the machine-hour yield, and is environment-friendly.
本发明公开了一种水性多羟基共聚物，其制备方法包括如下步骤：将三乙醇胺油酸皂、烯丙基琥珀酰亚胺基碳酸酯、丁香酚芸香糖苷、双三甲基硅基化乙烯基磷酸酯溶于高沸点溶剂中形成溶液，再向溶液中加入引发剂，置于微波炉中，在氮气或惰性气体氛围下进行微波聚合反应10‑15分钟，反应后取出，倒入丙酮中沉出聚合物，抽滤，放入真空干燥箱中60‑70℃下烘10‑15小时，得到多羟基共聚物。由多羟基共聚物制得的水泥助磨剂具有生产成本低廉，掺量低，能有效改善水泥的润滑性等性能和台时产量，助磨增强效果显著，使用安全环保的优点。
