Lightweight heat preservation and insulation base material, preparation method thereof and lightweight heat preservation and insulation material
The invention relates to a light heat preservation and insulation base material, a preparation method thereof and a light heat preservation and insulation material, and belongs to the technical field of heat preservation and insulation materials. The preparation method of the light thermal insulation base material comprises the following steps: mixing inorganic fibers, an inorganic porous material and water to obtain a mixed fiber suspension; mixing the mixed fiber suspension with a foaming agent, and carrying out mixed foaming to obtain foam slurry; the foam slurry is subjected to slurry distribution and forming, a wet paper sheet is obtained, and the light heat preservation and heat insulation base material is obtained through foam elimination and drying. The lightweight thermal insulation base material prepared by the preparation method of the thermal insulation base material provided by the invention has better uniformity, lower density, higher porosity and higher aerogel loading capacity, and the thermal insulation material containing the lightweight thermal insulation base material has the advantages of light weight, excellent thermal insulation performance and temperature resistance.
