Thermal insulation material as well as preparation method and application thereof
The invention provides a thermal insulation material as well as a preparation method and application thereof, and relates to the technical field of porous materials. In the thermal insulation material provided by the invention, the inorganic fibers, the organic fibers and the filler form a first-stage network structure, the inorganic fibers are thin, long and stiff, the organic fibers are thin, long and soft, and the long fibers of the inorganic fibers and the organic fibers are distributed in a staggered manner to form a microscopic multi-stage pore network structure. The nano cellulose is added, so that the nano cellulose is filled between the inorganic fibers and the organic fibers, and a submicron microscopic multi-stage pore network structure is formed. The thermal insulation material provided by the invention is high in physical strength and good in heat resistance and flame retardance, adapts to complex geometrical shapes, does not burn, does not generate smoke, does not break or break after being treated at a high temperature (600 DEG C), keeps the original complete shape and form, and completely meets the mechanical and thermal property requirements of the thermal insulation material for the automobile engine and the exhaust manifold.
本发明提供了一种隔热材料及其制备方法和应用，涉及多孔材料技术领域。本发明提供的隔热材料中，无机纤维、有机纤维和填料形成第一级网络结构：无机纤维细长、挺硬，有机纤维细长、柔软，这些无机纤维和有机纤维的长纤维互相交错分布，形成微观多级孔隙网络结构。通过添加纳米纤维素，使得纳米纤维素填充在上述无机纤维和有机纤维之间，形成亚微米级的微观多级孔隙网络结构。本发明提供的隔热材料的物理强度高、耐热性和阻燃性好，适应复杂几何形状，高温(600℃)处理后时不燃烧、不产生烟气、不破碎、不断裂、保持原有完整形状和形态，完全满足汽车发动机和排气歧管用隔热材料的力学和热学性能要求。
