Fiber-reinforced porous thermal insulation material and preparation method thereof
The invention discloses a fiber-reinforced porous thermal insulation material, the fiber-reinforced porous thermal insulation material is prepared by adopting a dry pressing method, and the preparation raw materials of the fiber-reinforced thermal insulation material comprise the following components: compressible powder, refractory fibers, an infrared opacifying agent and cellulose nanofibers. According to the fiber-reinforced porous thermal insulation material, the cellulose nanofibers are adopted as a forming reinforcing agent for the first time, a large-size fiber-reinforced porous thermal insulation material blank is successfully prepared under the condition that other binders are not added, the conditions of cracking, corner breaking and the like on the surface of the blank do not occur, and the highest use temperature can reach 1500 DEG C; the comprehensive performance of the fiber-reinforced porous thermal insulation material is effectively improved. Meanwhile, the invention also discloses a method for preparing the fiber-reinforced porous thermal insulation material by the dry pressing method, and the method does not need drying, not only is high in preparation speed, but also is low in production cost, greatly shortens the production process, and is easy for large-scale production.
本发明公开一种纤维增强多孔隔热材料，所述纤维增强多孔隔热材料采用干压法制备而成，且所述纤维增强隔热材料的制备原料包含以下成分：可压缩粉体、耐火纤维、红外遮光剂、纤维素纳米纤维。本发明所述纤维增强多孔隔热材料，首次采用纤维素纳米纤维作为成型增强剂，在未添加其他粘结剂的情况下成功制备出了大尺寸纤维增强多孔隔热材料胚体，胚体表面没有开裂、缺角等情况发生，且最高使用温度最高可以达到1500℃，有效提高了纤维增强多孔隔热材料的综合性能。同时，本发明还公开了一种干压法制备纤维增强多孔隔热材料的方法，所述方法不需干燥，不仅制备速度快，而且生产成本低，大大缩短了生产流程，易于大规模生产。
