摘要
运用溶胶-凝胶法、自组装等先进技术制备出三维有序大球多孔TiO_2微球,引发TPEG、AA、HEMA共聚得到聚羧酸减水剂,通过水泥净浆流动度及液相色谱测试表明,所制备的减水剂减水率高,分散性好。
A series of three-dimensional spherical macroporous TiO2 microspheres were prepared by sol-gel method and self-assembly technique. TPCA, AA and HEMA were copolymerized to obtain polycarboxylate water-reducing agent. Through the fluidity of cement paste and liquid chromatography The results show that the prepared water reducing agent has high water-reducing rate and good dispersibility.
