Preparation of modified glutinous rice mortar with high bonding strength
The invention discloses preparation of high-bonding-strength modified glutinous rice mortar, and relates to the technical field of glutinous rice mortar. The preparation method of the modified glutinous rice mortar comprises the following steps: attaching nano silicon dioxide to flaky graphene oxide by adopting a sol-gel method to obtain a GO/NS hybrid, and then preparing the GO/NS hybrid into a dispersion liquid to obtain a GO/NS hybrid dispersion liquid; and mixing slaked lime with the glutinous rice slurry, adding the GO/NS hybrid dispersion liquid, and stirring to obtain the modified glutinous rice mortar. The advantage that flaky GO and a nano material have good compatibility is utilized, the flaky GO is used as a carrier to attach NS to the surface, then a graphene oxide-nano silicon dioxide (GO/NS) hybrid is introduced into a glutinous rice mortar matrix, the modification effect of the glutinous rice mortar is greatly improved, and then a good historic building repairing effect is guaranteed.
本发明公开了一种高粘结强度改性糯米灰浆的制备，涉及糯米灰浆技术领域。本发明改性糯米灰浆的制备方法包括以下步骤：采用溶胶‑凝胶法将纳米二氧化硅附着在片状氧化石墨烯上，得到GO/NS杂化物，之后将GO/NS杂化物配置成分散液，得到GO/NS杂化物分散液；将熟石灰与糯米浆混合，加入GO/NS杂化物分散液、搅拌后得到改性糯米灰浆。本发明利用片状GO与纳米材料具有良好兼容性的优势，以片状GO为载体将NS附着于表面，然后将氧化石墨烯‑纳米二氧化硅(GO/NS)杂化物引入糯米灰浆基体中，大幅度提高糯米灰浆的改性效果，进而保证了良好的古建筑修复效果。
