Zirconium-containing nanoscale microporous high-temperature-resistant super thermal insulation material
The invention discloses a zirconium-containing nanoscale microporous high-temperature-resistant super thermal insulation material which comprises a surface layer structure and an inner layer structure, wherein the surface layer structure comprises the following components: 45-55% of reinforced zirconium-containing aluminum silicate fiber; 15%-25% of nanoscale silicon dioxide powder and 10%-20% of nanoscale zircon sand powder; 15 to 25% of anti-infrared radiation powder; 0.1-0.5% of nano high-temperature expanded graphite and 2-5% of an inorganic binder; the inner layer structure comprises the following components: 50-75% of reinforced zirconium-containing aluminum silicate fiber; 10%-20% of nanoscale silicon dioxide powder and 5%-10% of nanoscale zircon sand powder; 10-20% of anti-infrared radiation powder, and 2-5% of an inorganic binder. Two materials with different temperature layers are compounded, the material with large density and small heat conductivity coefficient is placed on the surface layer, and then the material with small density and large heat conductivity coefficient is placed on the inner layer. The heat insulation material is formed by compounding two layers of materials suitable for different temperature intervals, the defects of a single-layer nanoscale microporous heat insulation material structure are overcome, and the performance and the high temperature resistance of the heat insulation material are improved by using the materials with different densities and different heat conductivity coefficients.
