High-infrared reflectivity high-aluminum light fire-resistant thermal insulating material and preparation method thereof
The invention relates to a high-infrared reflectivity high-aluminum light fire-resistant thermal insulating material and a preparation method thereof. According to the technical scheme of the High-infrared reflectivity high-aluminum light fire-resistant thermal insulating material and the preparation method thereof, 20-40 wt% of potassic raw material, 50-70wt% of titaniferous raw material and 5-10 wt% of 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. 20-40 wt% of alumina particles, 10-25 wt% of alumina fine powders, 5-15 wt% of A material, 5-15 wt% of B material, 5-15 wt% of aluminiferous raw material and 2-10 wt% of potassic raw material are used as mixture, water containing 2-8 wt% of the micture are added, a green body is made by stirring, drying is conducted, cooling is conducted after the thermal treatment is conducted, the green body is soaked with water, then drying is conducted, and the high-infrared reflectivity high-aluminum light fire-resistant thermal insulating material is obtained. The high-infrared reflectivity high-aluminum light fire-resistant thermal insulating material has the advantages that the volume density is low, the compression strength is high, and the high-temperature heat conductivity coefficient is low. The high-infrared reflectivity high-aluminum light fire-resistant thermal insulating material can also be applied to the heat insulation field within 1300 DEG C for a long time.
