Composite nano material for anti-seepage separation wall and preparation method thereof
The invention provides a composite nano material for an anti-seepage separation wall and a preparation method of the composite nano material. The method comprises the following steps: grinding kaolinite, montmorillonite, illite and diatomite into powder to obtain a first mixture; dispersing the first mixture into water to form a first mixed solution; adding tetramethyl ammonium oxalate, n-butyl lithium, sodium silicate, sodium dodecyl sulfate and sodium stearate into the first mixed solution; filtering to obtain a second mixed solution, adding triethanolamine, triisopropanolamine, acrylic acid, methacrylic acid and a polyether into the second mixed solution; after ball milling, magnetically stirring to obtain a third mixed solution; carrying out centrifugal vacuum drying on the third mixedsolution to obtain the composite nanomaterial for the anti-seepage separation wall. The composite nano material has self-dispersibility, can chemically react with cations released in a cement hydration process to generate amorphous gel hydration products, and fillgaps of cement particles to construct a compact set cement microstructure, so that the macroscopic mechanical properties and durabilityare greatly improved.
本发明提供了一种用于防渗隔离墙的复合纳米材料及其制备方法，该方法包括将高岭石、蒙脱石、伊利石和硅藻土磨成粉得到第一混合物，将第一混合物分散到水中形成第一混合液，向第一混合液中加入四甲基草酸铵、正丁基锂、硅酸钠、十二烷基磺酸钠和硬脂酸钠，过滤得到第二混合液，在第二混合液中加入三乙醇胺、三异丙醇胺、丙烯酸、甲基丙烯酸和聚醚，球磨后磁力搅拌得到第三混合液，将第三混合液离心真空干燥，得到用于防渗隔离墙的复合纳米材料，复合纳米材料具有自分散性，可与水泥水化过程中释放的阳离子发生化学反应，生成无定形凝胶类水化产物，填充到水泥颗粒的空隙中，构建致密的水泥石微结构，使其宏观力学性能和耐久性能得到大幅提高。
