High-strength concrete viscosity-reducing anti-mud agent and preparation method thereof
The invention discloses a high-strength concrete viscosity-reducing anti-mud agent and a preparation method thereof. The preparation method comprises the following steps: preparing ethylene glycol acrylate from acrylic acid and ethylene glycol, and carrying out free radical copolymerization reaction on the ethylene glycol acrylate, acrylamide, itaconic acid, methyl acrylate and sodium allylsulfonate to prepare the viscosity-reducing anti-mud agent. The high-strength concrete viscosity-reducing anti-mud agent prepared by the invention can be used for reducing viscosity, increasing flow and resisting mud of concrete of C50 or above; the problems of mud resistance of high-strength concrete and high viscosity and poor fluidity in pumping construction are solved; meanwhile, the concrete additive has a mud-resistant function, is suitable for preparation of high-performance concrete, can significantly improve the mud resistance, fluidity and pumpability of fresh concrete and the strength anddurability of hardened concrete, and is relatively low in price, simple in preparation process, less in pollution, high in cost performance and high in practicability.
本发明公开了一种高强度混凝土降黏抗泥剂及其制备方法，首先由丙烯酸与缩乙二醇制备丙烯酸缩乙二醇酯，然后丙烯酸缩乙二醇酯、丙烯酰胺、衣康酸、丙烯酸甲酯、丙烯磺酸钠通过自由基共聚反应制备降黏抗泥剂。本发明制得的高强度混凝土降黏抗泥剂可用于C50以上混凝土的降黏增流和抗泥，解决了高强度的混凝土的抗泥及泵送施工遇到的黏度大流动性差的问题，同时具有抗泥的功能，适用于高性能混凝土的制备，能够显著地增加新拌混凝土抗泥性、流动性、泵送性及硬化混凝土的强度和耐久性，价格较低，且制备工艺简单污染少，性价比高，实用性强。
