Preparation method of ultralight inorganic homogeneous thermal insulation material, ultralight inorganic homogeneous thermal insulation material and application of ultralight inorganic homogeneous thermal insulation material
The invention discloses a preparation method of an ultralight inorganic homogeneous thermal insulation material, the ultralight inorganic homogeneous thermal insulation material and application, and belongs to the technical field of thermal insulation building materials. Comprising superfine cement, superfine powder, a surfactant, cellulose ether, aerogel powder, ultra-short fibers, a pore-forming agent and water. The preparation method comprises the following steps: 1, slurry preparation, 2, aerogel light slurry preparation, 3, foaming slurry preparation, 4, thermal insulation material green body forming and 5, green body maintenance. A combined pore-forming technology, namely a two-time foaming process (air is introduced through high-speed stirring for the first time, and oxygen or hydrogen is generated through a chemical reaction for the second time) is adopted, the pore structure and pore size grading are optimized, and the thermal insulation material is prepared through the steps of 1, slurry preparation, 2, aerogel light slurry preparation, 3, foaming slurry preparation, 4, thermal insulation material green body forming and 5, green body maintenance. The uniformity and the closed porosity of pores are improved, and the stability, the uniformity and the roundness value of bubbles in the slurry are improved. The combined pore-forming technology integrates the comprehensive advantages of a physical foaming process and a chemical foaming process; the aerogel powder is doped, the thermal insulation performance of the product is improved through the synergistic effect of the air holes and the aerogel powder, and the heat conductivity coefficient is reduced.
