High-infrared reflectivity spinel light fire-resistant thermal insulating material and preparation method thereof
The invention relates to a high-infrared reflectivity spinel light fire-resistant thermal insulating material and a preparation method thereof. According to the scheme of the high-infrared reflectivity spinel light fire-resistant thermal insulating 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 and E material with particle size smaller than 0.088 mm are obtained; finally, the magnesium aluminate spinel particles, magnesium aluminate spinel fine powders, the A material, the D material, the E material, the magniferous raw material, the aluminiferous raw material and the potassic raw material are mixed, water is added, the stirring is conducted, drying is conducted on a green body formed by pressing, the green body is soaked with water after thermal treatment is conducted, and drying is conducted. The prepared product is low in volume density, high in compression strength and low in high-temperature heat conductivity coefficient.
