Polycarboxyl density functional polycarboxylic acid water reducer and preparation method thereof
The invention discloses a multi-carboxyl density functional polycarboxylic acid water reducer and a preparation method thereof. The polycarboxylate superplasticizer is composed of acrylic acid, acrylamide, styrene, hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxybutyl acrylate, maleic acid, acrylate and hydroxyethyl propyl acrylate monomers, and comprises three polymers (I), (II) and (III), and the molar ratio of the three polymers can be optimized. The preparation method comprises the steps of preparing monomers and reaction conditions, synthesizing polymers (I), (II) and (III), optimizing the proportion, adjusting the performance and the like. The polycarboxylate superplasticizer is suitable for cement concrete, and can significantly improve the fluidity, ductility and crack resistance of concrete.
本发明公开了一种多羧基密度功能型聚羧酸减水剂及其制备方法。所述聚羧酸减水剂由丙烯酸、丙烯酰胺、苯乙烯、丙烯酸羟乙酯、丙烯酸羟丙酯、丙烯酸羟丁酯、马来酸、丙烯酸酯和丙烯酸羟乙基丙酯单体组成，包括三种聚合物(I)、(II)和(III)，它们的摩尔比例可通过优化配比得到。本发明制备方法包括准备单体和反应条件、合成聚合物(I)、(II)和(III)、优化配比、调整性能等步骤。所述聚羧酸减水剂适用于水泥混凝土中，可显著提高混凝土的流动性、延展性和抗裂性能。
