High-temperature rollable micro-nano hierarchical porous inorganic composite thermal insulation material and low-carbon preparation method thereof
The invention discloses a high-temperature rollable micro-nano hierarchical porous inorganic composite thermal insulation material and a low-carbon preparation method thereof, and belongs to the technical field of inorganic thermal insulation materials. The composite thermal insulation material is of a three-layer structure including an inner layer, a middle layer and an outer layer. The outer layer has the most fibers and contains a certain amount of water, so that the material is endowed with better curling performance; the porosity of the middle layer is maximum, and micron-nano multi-stage cavity holes are formed, so that the heat insulation performance is improved; and the inner layer improves the high-temperature resistance of the material. The composite thermal insulation material disclosed by the invention has the characteristics of good comprehensive performance, such as fire prevention, small thermal conductivity (small thermal conductivity change at high temperature), good flexibility and the like.
本发明公开了一种高温用可卷曲微纳米多级孔隙无机复合保温材料及其低碳制备方法，属于无机绝热材料技术领域。本发明的复合保温材料为内、中、外层的三层结构；外层纤维最多，且含一定量水，赋予材料更好的卷曲性能；中层孔隙率最大，且形成微米纳米多级腔孔，提高绝热性能；内层则提高材料的耐高温能力。本发明的复合保温材料具有良好的综合性能，如防火、热导率小(高温时热导率变化小)、柔韧性好等特点。
