Ultrahigh-flame-retardant external wall thermal insulation material as well as preparation method and application thereof
The invention discloses an ultrahigh-flame-retardant external wall thermal insulation material and a preparation method and application thereof, and belongs to the field of building thermal insulation materials.The preparation method comprises the following steps that chitosan and acetic acid are added into a solvent to be mixed, and a chitosan solution is obtained; performing ultrasonic dispersion treatment on the chitosan solution and glass fibers to obtain a mixed solution; placing the mixed solution in a mold, then placing the mold on a cooling plate for oriented freezing, and then performing freeze drying treatment to obtain the ultrahigh flame-retardant external wall thermal insulation material. The prepared material is of a porous structure and has a stable oriented lamellar structure, so that the material has excellent flame retardance, heat insulation and mechanical strength. The material can be used as a building external wall thermal insulation material, and has excellent thermal insulation performance, fireproof and smoke suppression performance, mechanical performance and constructability.
本发明公开了一种超高阻燃外墙保温材料及其制备方法和应用，其属于建筑保温材料领域，其中，该制备方法包括以下步骤：将壳聚糖与乙酸加入到溶剂中进行混合，得到壳聚糖溶液；将壳聚糖溶液与玻璃纤维进行超声分散处理，得到混合液；将混合液置于模具中，然后将模具置于冷却板上进行取向冷冻，后经冷冻干燥处理，得到超高阻燃外墙保温材料。本发明制得的材料为多孔结构，且具有稳定的取向片层结构，从而使材料具有优异的阻燃隔热与力学强度。该材料可以作为建筑外墙保温材料，具有优良的保温性能、防火抑烟性能、机械性能以及可施工性。
