Preparation method of composite doped bentonite modifier and waterproof material
The invention discloses a preparation method of a composite doped bentonite modifier, which is based on the Ostwald ripening principle, under the driving of certain high temperature and high pressure, sufficient and effective doping of different inorganic ions such as Mg < 2 + >, Na < + > and Al < 3 + > in molecule, atom and ion levels, regulation and control of doping concentration and other factors are realized, and the composite doped bentonite modifier is prepared. The bentonite modifier fully exerts respective synergistic interaction characteristics of different inorganic ions, can achieve a solid solution strengthening effect after co-doping, can comprehensively improve the impermeability, mechanical properties and the like of concrete after being applied to the concrete, ensures good mechanical properties while improving the impermeability of the concrete, and has good application prospects. The synergistic enhancement effect is achieved.
本发明公开了一种复合掺杂型膨润土改性剂的制备方法，该制备方法基于奥斯瓦尔德熟化原理，在一定的高温高压驱动下，实现Mg2+、Na+和Al3+不同无机离子在分子、原子、离子水平的充分有效掺杂，调控掺杂浓度等因素，充分发挥不同无机离子各自的协同增效特性，可以实现膨润土改性剂发挥共掺后的固溶强化效果，应用于混凝土中后可以起到综合提升混凝土抗渗性能、力学性能等，在混凝土抗渗性能提升的同时保证了良好的力学性能，达到了协同增强作用。
