High-strength low-thermal conductivity ceramic fiber thermal insulation material and preparation method thereof
The invention relates to a high-strength low-thermal conductivity ceramic fiber thermal insulation material and a preparation method thereof. According to the technical scheme of the high-strength low-thermal conductivity ceramic fiber thermal insulation material and the preparation method thereof, titaniferous raw material, magniferous raw material and binding agents are uniformly mixed, grinding is conducted after molding and thermal treatment are conducted, and A material with particle size ranging from 0.088-1 mm and B material with particle size smaller than 0.088 mm are obtained; potassic raw material, titaniferous raw material and the binding agent are uniformly mixed, grinding is conducted after molding and thermal treatment are conducted, and c material with particle size smaller than 0.088 mm is obtained; then the A material, the B material, the C material and the potassic raw material are mixed uniformly, grinding is conducted after thermal treatment is conducted, and D material with particle size ranging from 0.088-1 mm is obtained; the pretreated ceramic fiber, the B material, the C material, the D material, the binding agent and additive are mixed uniformly, water is added, stirring is conducted, the mixed solution is poured into a die, and the high-strength low-thermal conductivity ceramic fiber thermal insulation material is obtained through the steps of vacuum dewatering, drying and thermal treatment. The high-strength low-thermal conductivity ceramic fiber thermal insulation material and the preparation method thereof have the advantages are low in cost, the prepared product is low in volume density, high in breaking strength and low in high-temperature heat conductivity coefficient.
