The invention relates to lime paste-based mortar and a preparation method thereof, and belongs to the technical field of building materials, the lime paste-based mortar comprises the following raw materials: gypsum clinker, quick lime, coal ash slag, an epoxy resin mortar adhesive, a modified water-retaining agent, a water reducing agent and deionized water; the epoxy resin mortar adhesive is prepared by reacting silane modified montmorillonite with modified epoxy resin, and the modified epoxy resin is prepared by modifying isocyanate; the modified water-retaining agent is prepared through reaction of modified halloysite nanotubes and hydroxypropyl methyl cellulose ether, epoxy resin chains are inserted into gaps of a silane-montmorillonite layer, formation of an epoxy resin cross-linked network is promoted, the adhesiveness of the lime paste-based mortar is further enhanced, the halloysite nanotubes are grafted to the surface of the hydroxypropyl methyl cellulose ether, and the adhesion of the lime paste-based mortar is improved. A polymer chain is formed, and the compatibility of the adhesive and the water-retaining agent is enhanced, so that the lime paste-based mortar has good water-retaining property and bonding property.
本发明涉及一种石灰膏基砂浆及其制备方法，属于建筑材料技术领域，包括以下原料：石膏熟料、生石灰、煤灰渣、环氧树脂砂浆粘合剂、改性保水剂、减水剂和去离子水；所述环氧树脂砂浆粘合剂通过硅烷改性蒙脱石与改性环氧树脂反应制得，改性环氧树脂由异氰酸酯改性制得；所述改性保水剂由改性埃洛石纳米管与羟丙基甲基纤维素醚反应制得，环氧树脂链插入硅烷‑蒙脱石层的间隙中，促进了环氧树脂交联网络的形成，进而增强了石灰膏基砂浆的粘合性，将埃洛石纳米管接枝在羟丙基甲基纤维素醚表面，形成聚合物链，增强了粘合剂和保水剂的相容性，进而使得石灰膏基砂浆在具有良好的保水性能和粘合性能。
