▎ 摘　　要

NOVELTY - Preparing high-strength low-thermal conductivity ceramic gas gel material comprises (i) preparing fiber film by electrostatic spinning, mixing TEOS, hydrogen peroxide and water and fully stirring to prepare silica sol A, adding polyvinyl alcohol solution into the silica solution A, stirring to obtain precursor solution, (ii) preparing nano-sheet slurry, (iii) placing the fiber/sol dispersion into the prepared mold, freezing and molding, drying the frozen block, (iv) sintering the silicon dioxide fiber gas gel in step (iii), (v) pouring the graphene dispersion liquid into the mold, immersing the SiO2 nanofiber gas gel, dipping for 15-30 minutes under vacuum, (vi) freezing and forming the dispersion solution, and (vii) drying the freeze block, aerogel the material with bamboo joint-shaped hole structure. USE - Preparation method of high-strength low thermal conductivity ceramic gas material gel. ADVANTAGE - The method provides high strength and low thermal conductivity ceramic gas material gel bamboo joint shaped hole structure, solves the problem that the gas gel low intensity, bad structure stability and high thermal conductive in the existing technology, has a bamboo joint-shaped hole structure, can greatly improve the strength of the ceramic gel and reduce the thermal conduction. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating a preparation method of high-strength low thermal conductivity ceramic gas material gel (Drawing includes non-English language text).
