▎ 摘　　要

NOVELTY - Preparing high-temperature resistant ultra-light ceramic fiber porous elastomer material involves uniformly dispersing ceramic micron fiber dispersion, surfactant and water at high-speed to form ceramic micromaterial dispersion liquid, adding graphene oxide solution, reducing agent and agglomerant, and stirring uniformly to obtain ceramic micron material/graphene composite wet gel, pre-freezing and freeze-drying the ceramic micron material/graphene complex wet gel sequentially to obtain a ceramic micro material/ graphene compound foam, and sequentially subjecting to a thermal annealing treatment at 1600℃ for 0.1-2 hours under an inert atmosphere and an air atmosphere at 300-800℃ at a constant temperature for 1-6 hours to obtain the final product. USE - The high temperature resistant ultra-light ceramic fiber porous elastomer material prepared by the method used as a high-temperature-resistant reinforcement and an infrared light-shielding body or an ultra-light elastic airgel material (claimed). ADVANTAGE - The high temperature resistant ultra-light ceramic fiber porous elastomer material can be directly commercial, shelf ceramic micro-fibre product as starting raw material, can be prepared in a simple and cost effective manner, and can realize macroscopic large size preparation, and is good for practical engineering application. The temperature limit of the material is not less than 1400℃. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a high temperature resistant ultra-light ceramic fiber porous elastomer material.
