6C early-strength tackifying functional polycarboxylate superplasticizer and preparation method thereof
The invention discloses a 6C early-strength tackifying functional polycarboxylic acid water reducer and a preparation method thereof, and belongs to the technical field of building chemical materials. The 6C early-strength tackifying functional polycarboxylic acid water reducer comprises a base material, an additive and a neutralizer, wherein the backing material is prepared by dissolving a six-carbon macromonomer, polyoxyethylene, hydrogen peroxide and nano titanium dioxide in water; the additive is composed of a class A and a class B, the class A is an aqueous solution of thiohydracrylic acid, and the class B is an aqueous solution of acrylic acid and hydroxyethyl methylacrylate; the neutralizer is an aqueous solution of sodium hydroxide. The polycarboxylate superplasticizer prepared by the method has multiple effects of water reduction, early strength, tackifying and the like, so that the rebound rate in a sprayed concrete construction process is reduced, and the polycarboxylate superplasticizer has a relatively good application prospect.
本发明公开了一种6C早强增粘功能型聚羧酸减水剂及其制备方法，属于建筑化学材料技术领域。本发明6C早强增粘功能型聚羧酸减水剂，包括底料、添加料和中和剂；其中，所述底料由六碳大单体、聚氧化乙烯、双氧水和纳米二氧化钛溶于水制成；所述添加料由A、B两类组成，其中，A类为巯基丙酸的水溶液，B类为丙烯酸和甲基丙烯酸羟乙酯的水溶液；所述中和剂为氢氧化钠的水溶液。本发明方法制备的聚羧酸减水剂具有减水、早强及增粘等多重效果，从而降低喷射混凝土施工过程中的回弹率，具有较好的应用前景。
