High-strength low-thermal-conductivity silicon oxide-based thermal insulation material as well as preparation method and application thereof
The invention relates to the technical field of thermal insulation materials, and provides a high-strength low-thermal-conductivity silicon oxide-based thermal insulation material as well as a preparation method and application thereof. The fiber cloth laminated prefabricated member comprises a laminated structure formed by sequentially laminating five layers of quartz fiber cloth and one layer of carbon fiber cloth, and a quartz suture line for stitching the laminated structure; the silicon oxide ceramic substrate is of a porous structure formed by nano silicon oxide, and the particle size range of the nano silicon oxide is 120-180nm; the fiber cloth laminated prefabricated member accounts for 65-80% of the total mass, the silicon oxide ceramic matrix accounts for 20-35% of the total mass, and the porosity of the material is 30-45%; the preparation method comprises the following three steps: preparing a fiber cloth laminated prefabricated part, preparing a laminated prefabricated part/gel complex, and carrying out high-temperature heat treatment. The prepared material has high strength and low thermal conductivity, and the material preparation process is simple, safe, environment-friendly and easy for large-scale production and application.
