Lightweight high-temperature-resistant wave-transparent low-cost heat prevention and insulation silicon-based material and preparation method thereof
The invention provides a light high-temperature-resistant wave-transparent low-cost heat prevention and insulation silicon-based material and a preparation method thereof. The method comprises the following steps: designing thickness and material systems of a core layer, an upper surface layer and a lower surface layer, and preparing a thickness-controllable and system-adjustable ceramic composite material preform; clamping the prepared ceramic composite material preform by using a mold, dipping in a silica sol solution, then curing, and repeatedly dipping and curing for 3-5 times; and under a vacuum condition, cracking and firing the treated ceramic composite material preform, and cooling to room temperature to obtain the light high-temperature-resistant wave-transparent low-cost heat-proof and heat-insulating silicon-based material. According to the prepared light high-temperature-resistant wave-transparent low-cost heat-proof and heat-insulating silicon-based material, only one set of mold is needed for controlling the thickness and the shape in the compounding process, the production cost is reduced, the preparation period is effectively shortened, the preparation efficiency is improved, the operation is simple, and the prospect of large-scale production and preparation of ceramic-based composite materials in the industrial field is wide.
本发明提供了一种轻质耐高温透波低成本防隔热硅基材料及制备方法，该方法包括设计芯层、上表面层和下表面层厚度与材料体系，制备厚度可控与体系可调的陶瓷复合材料预制体；将制备的陶瓷复合材料预制体用模具夹紧，浸渍于硅溶胶溶液中，然后固化，反复浸渍和固化3‑5次；在真空条件下，对处理后的陶瓷复合材料预制体进行裂解烧成，冷却至室温，得到轻质耐高温透波低成本防隔热硅基材料。制得的轻质耐高温透波低成本防隔热硅基材料在复合过程中仅需要一套模具进行厚度与形状的控制，降低了生产成本，有效的缩短了制备周期，提高了制备效率，操作简单，在工业领域成为大规模生产制备陶瓷基复合材料的前景广阔。
