The invention discloses a high-strength thermal-insulation composite board for buildings and a preparation method thereof, and belongs to the technical field of building materials. The preparation method comprises the following steps: reacting bamboo charcoal fibers with potassium permanganate in concentrated sulfuric acid, dropwise adding hydrogen peroxide to obtain modified bamboo charcoal fibers, and filling the modified bamboo charcoal fibers with nano calcium carbonate coated and modified by undecylamine and dodecylamine, adding thermotropic liquid crystal polyarylester fiber treated by nitrogen plasma into the modified bamboo charcoal fiber dispersion liquid filled with the modified nano calcium carbonate, carrying out cross-linking reaction, and drying and dehydrating to obtain the high-strength thermal-insulation composite board for the building. The high-strength thermal-insulation composite board for the building prepared by the invention has excellent thermal insulation performance and breaking strength.
本发明公开了一种建筑用高强度保温复合板及其制备方法，属于建筑材料技术领域。本发明先用竹炭纤维与高锰酸钾在浓硫酸中反应，再滴加过氧化氢，制得改性竹炭纤维，然后将经过十一烷胺和十二烷胺包覆改性后的纳米碳酸钙对改性竹炭纤维进行填充，最后将经氮等离子体处理后的热致液晶聚芳酯纤维加入改性纳米碳酸钙填充后的改性竹炭纤维分散液中进行交联反应，干燥脱水后即得建筑用高强度保温复合板。本发明制备的建筑用高强度保温复合板具有优异的保温性能和断裂强度。
