High-temperature thermal insulation material and preparation method thereof
The invention relates to the technical field of thermal insulation materials, and particularly discloses a high-temperature thermal insulation material and a preparation method thereof. The high-temperature thermal insulation material is prepared from the following raw material components in parts by weight: 150 to 200 parts of nano sol, 10 to 30 parts of inorganic high-temperature fiber material, 3 to 5 parts of silica fume, 70 to 80 parts of alpha-alumina powder and 3 to 5 parts of sintering agent. A preparation method of a high-temperature thermal insulation material comprises the following steps: firstly, adding an inorganic high-temperature fiber material into nano sol, stirring until the inorganic high-temperature fiber material is completely dissolved, then adding silica fume, alpha-alumina powder, a sintering agent and other raw materials, and continuously stirring until the inorganic high-temperature fiber material is completely dissolved to obtain a material; the materials are pumped into a mold, then vacuumizing is conducted till the vacuum degree reaches-0.07 MPa to-0.08 MPa till the materials are completely solidified, a blank is obtained, the blank is dried and machined, and the high-temperature heat insulation material is obtained.
