High-infrared-reflectivity forsterite lightweight refractory and thermal insulation material and preparation method thereof
The invention relates to a high-infrared-reflectivity forsterite lightweight refractory and thermal insulation material and a preparation method thereof. According to the technical scheme, the method comprises the following steps: uniformly mixing a titanium-containing raw material, a magnesium-containing raw material and a binding agent, molding, carrying out heat treatment, and grinding, thus obtaining an A material with a particle size of 0.088-1mm and a B material with a particle size of less than 0.088mm; uniformly mixing a potassium-containing raw material, a titanium-containing raw material and a binding agent, molding, carrying out heat treatment, and grinding, thus obtaining a C material with a particle size of 0.088mm; uniformly mixing the A material, the B material, the C material and a potassium-containing raw material, carrying out heat treatment, and grinding, thus obtaining a D material with a particle size of 0.088-1mm and an E material with a particle size of 0.088mm; and finally, mixing forsterite particles, fine forsterite powder, the A material, the D material, the E material, a magnesium-containing raw material, a silicon-containing raw material and a potassium-containing raw material, molding, drying, carrying out heat treatment, cooling, soaking and drying. The prepared high-infrared-reflectivity forsterite lightweight refractory and thermal insulation material is low in volume density, high in compression strength, and low in high-temperature heat conductivity coefficient.
