High-strength thermal insulation mortar and preparation method thereof
The invention discloses high-strength thermal insulation mortar and a preparation method thereof, and belongs to the technical field of building materials. The high-strength thermal insulation mortar is prepared from the following raw materials: Portland cement, glass beads, mineral filler, a functional phase change material, nano montmorillonite, dispersible latex powder, an air entraining agent, a water-retaining agent, a retarder and water. Wherein the functional phase-change material is obtained after composite aggregate is subjected to vacuum impregnation in a melting solution of polyvinyl alcohol and stearyl alcohol, and the composite aggregate comprises nano titanium dioxide and pretreated aluminum silicate fiber aerogel. When being applied to building construction, the thermal insulation mortar prepared by the invention has the characteristics of high strength, good durability and excellent thermal insulation effect, and does not have the problems of cracking, hollowing and falling off.
本发明公开了一种高强度保温砂浆及其制备方法，属于建筑材料技术领域。所述高强度保温砂浆包括以下原料：硅酸盐水泥、玻化微珠、矿质填料、功能化相变材料、纳米蒙脱土、可分散乳胶粉、引气剂、保水剂、缓凝剂和水。其中，功能化相变材料通过复合骨料在聚乙烯醇与硬脂醇的熔化液中真空浸渍后得到，所述复合骨料包括纳米二氧化钛与前处理硅酸铝纤维气凝胶。本发明制备的保温砂浆在建筑物施工应用时，具有强度高，耐久性好，保温隔热效果优异的特点，也不会出现开裂、空鼓、脱落的问题。
