High-strength high-temperature-resistant thermal insulation material and preparation method thereof
The invention relates to a high-strength high-temperature-resistant thermal insulation material and a preparation method thereof. The method comprises the following steps: uniformly dispersing zirconium oxide fibers and a dispersing aid with water to obtain fiber slurry; adding magnesia and phosphate into the fiber slurry, and uniformly dispersing to obtain mixed slurry; uniformly mixing phenolic resin and a curing agent by using an alcohol solvent to obtain a phenolic resin solution; uniformly mixing the mixed slurry and the phenolic resin solution, reacting, and drying to obtain the composite thermal insulation material, and carbonizing the composite thermal insulation material to prepare the high-strength high-temperature-resistant thermal insulation material. The prepared novel organic-inorganic hybrid high-strength high-temperature-resistant heat-insulating material has the characteristics of good high-temperature resistance, excellent high-temperature heat-insulating property and excellent high-temperature mechanical property.
