Preparation method of zirconia-improved floating bead-based light thermal insulation material
The invention discloses a preparation method of a zirconium oxide improved floating bead based light thermal insulation material, and belongs to the technical field of preparation of light thermal insulation materials. The silicon dioxide floating beads are of hollow structures, have low density and heat conductivity and have good application prospects in the field of light heat insulation. Zirconium dioxide serving as an additive has a high refractive index and can serve as an opacifying agent to mask infrared light, radiation heat transfer of the material is reduced, and the heat insulation performance of the material is further improved; the preparation method comprises the following steps: mixing silicon dioxide floating beads and zirconium dioxide, adding a corresponding dispersing agent, a viscosity modifier and deionized water to prepare slurry with proper viscosity, printing heat insulation material blanks in various shapes by using a direct-writing 3D printer, and sintering to obtain the silicon dioxide floating bead-based light heat insulation material. And the application of the 3D printing technology can realize the rapid construction of complex parts, and has important significance on the actual use of materials.
