Fireproof heat-insulating ceramic fiber aerogel felt and preparation method thereof
The invention belongs to the field of aerogel materials, and discloses a fireproof heat-insulating ceramic fiber aerogel felt and a preparation method thereof, and is used for simplifying a traditional two-step compounding process, reducing the production cost and solving the problem that an existing ceramic fiber aerogel felt is non-uniform in powder compounding. The ceramic fiber aerogel felt ismainly composed of ceramic fiber paper and aerogel powder. The preparation method comprises the steps: in the traditional ceramic fiber paper preparation process, adding an aerogel precursor hydrolysate, and carrying out sol-gel and drying to prepare the ceramic fiber aerogel felt with fireproof and heat-insulating properties and uniform aerogel distribution, so that the ceramic fiber aerogel felt can be widely applied to the fields with fireproof and heat-insulating requirements, such as new energy, power batteries, buildings and industries.
本发明属于气凝胶材料领域，公开了一种防火隔热陶瓷纤维气凝胶毡及其制备方法，用于简化传统的两步法复合工艺，降低生产成本，并解决现有陶瓷纤维气凝胶毡粉体复合不均匀的问题。陶瓷纤维气凝胶毡，主要由陶瓷纤维纸和气凝胶粉体组成。制备方法为：在传统陶瓷纤维纸制备过程中，加入气凝胶前驱体水解液，经过溶胶‑凝胶、干燥，制备出具有防火隔热性能，且气凝胶分布均匀的陶瓷纤维气凝胶毡，可广泛应用于新能源、动力电池、建筑、工业等有防火隔热需求的领域。
