Method for preparing polycarboxylate water reducer by adopting C6 monomer
The invention discloses a method for preparing a polycarboxylate water reducer from a C6 monomer, and relates to the technical field of concrete admixtures. The method comprises the following steps: (1) adding deionized water and an ether C6 monomer into a reaction kettle, and stirring; (2) preparing a material A; (3) preparing a material B; (4) dropwise adding the material A, the material B, an ester C6 monomer and an oxidizing agent into the reaction kettle in the step (1) at the same time; and (5) dropwise adding alkali liquor into the reaction kettle in the step (4), and adjusting the pH value to 7 to obtain a target product. The polycarboxylate water reducer has the beneficial effects that the polycarboxylic acid water reducer is prepared by taking the ether C6 monomer and the ester C6 monomer as raw materials through reactions, and through the synergistic effect of the raw materials, the prepared water reducer is greatly improved in the aspect of water reducing performance, and also has a good performance in the aspects of mud resistance, collapse prevention, adaptability and the like.
本发明公开一种采用C6单体制备聚羧酸减水剂的方法，涉及混凝土外加剂技术领域，本发明包括以下步骤：(1)在反应釜中加入去离子水和醚类C6单体，搅拌；(2)A料配制；(3)B料配制；(4)向步骤(1)中的反应釜内同时滴加A料、B料、酯类C6单体和氧化剂；(5)向步骤(4)的反应釜内滴加碱液，调节pH值为7，即得到目标产物。本发明的有益效果在于：本发明以醚类C6单体和酯类C6单体为原料反应制备的聚羧酸减水剂，通过各原料协同作用，制得的减水剂不仅在减水性能方面有了很大的提高，而且在减水剂的阻泥、防坍塌、适应性等方面也有很好的表现。
