Preparation process of mud-resistant polycarboxylate superplasticizer
The invention relates to a preparation process of a mud-resistant polycarboxylate superplasticizer. The mud-resistant polycarboxylate superplasticizer comprises methacryloyloxyethyl trimethyl ammonium chloride, acrylic acid, hydrogen peroxide, ascorbic acid and a chain transfer agent, with the balance being water. The preparation process is simple, a reaction is carried out at normal temperature, and the whole production process is short in reaction time, low in energy consumption, low in cost, high in safety coefficient and easy for industrial production. The mud-resistant polycarboxylate superplasticizer prepared by the method has a remarkable effect on flooring with high mud content throughout the country, and is high in water-reducing rate, low in mixing amount and good in slump loss resistance. With the mud-resistant polycarboxylate superplasticizer, the defect that a conventional polycarboxylate superplasticizer in the current market is poor in adaptability when encountering flooring with large mud content can be overcome.
一种抗泥型聚羧酸减水剂制备工艺,包括甲基丙烯酰氧乙基三甲基氯化铵、丙烯酸、双氧水、抗坏血酸、链转移剂、余量为水。本发明制备工艺简单,反应在常温下进行,整个生产过程反应时间短,能耗低,成本低,安全系数高,易于工业化生产。本发明方法制作的抗泥型聚羧酸减水剂,针对全国含泥量高的地材,有显著的效果,减水率高,参量低,保坍性能好。能够弥补当今市场常规聚羧酸减水剂遇到含泥量大的地材时适应性差的缺点。
