Concrete water reducer and preparation method thereof
According to the concrete water reducing agent provided by the invention, the N-hydroxyphthalimide is adopted to modify the graphene oxide, and then the graphene-terminated polyoxyethylene ether is synthesized, so that the dispersion of the graphene in the concrete is promoted. The prepared concrete water reducing agent can improve the fluidity of cement paste, improve the rheological property of a cement-based material and improve the mechanical property after curing. The invention also provides a preparation method of the water reducing agent.
本发明提供了一种混凝土减水剂，所述减水剂采用N‑羟基邻苯二甲酰亚胺对氧化石墨烯进行改性，进而合成石墨烯封端的聚氧乙烯醚，促进了石墨烯在混凝土中的分散。由此制备得到的混凝土减水剂能够提高水泥净浆的流动度，改善水泥基材料的流变性能，提高固化后的力学性能。本发明还提供了所述减水剂的制备方法。
