Composite thermal insulation material and preparation method thereof
The invention discloses a composite heat-insulating material and a preparation method thereof, relates to the technical field of ceramic-based composite heat-insulating materials, and provides a composite heat-insulating material with low heat conductivity coefficient and good hydrophobic performance, the composite heat-insulating material comprises an aluminum-silicon aerogel layer and an aluminum-silicon microporous ceramic matrix layer combined with the aluminum-silicon aerogel layer; the aluminum-silicon aerogel layer comprises any one of silicon dioxide aerogel and aluminum oxide aerogel or a mixture of the silicon dioxide aerogel and the aluminum oxide aerogel; and the aluminum-silicon microporous ceramic matrix layer comprises any one of alumina microporous ceramic and mullite microporous ceramic. The composite thermal insulation material overcomes the limitation of ultralow strength of aerogel materials, and is low in heat conductivity coefficient and good in hydrophobic performance, so that the purposes of wide application range (building outer wall thermal insulation, pipeline thermal insulation and kiln thermal insulation) and medium (rainwater and water vapor in a kiln) erosion resistance are achieved.
本发明公开了一种复合绝热材料及其制备方法，涉及陶瓷基复合绝热材料技术领域，提供一种导热系数低、憎水性能好的复合绝热材料，包括包括铝硅系气凝胶层和与其相结合的铝硅系微孔陶瓷基体层；铝硅系气凝胶层包括二氧化硅气凝胶、氧化铝气凝胶的任意一种或两种混合；铝硅系微孔陶瓷基体层包括氧化铝微孔陶瓷、莫来石微孔陶瓷中的任意一种。复合绝热材料解决气凝胶材料超低强度的局限，材料导热系数低、憎水性能好，从而实现适用范围为广(建筑外墙保温，管道保温，窑炉保温)、抗介质(雨水，窑炉内水蒸汽)侵蚀的目标。
