Preparation method of silicate high-entropy aerogel with high emissivity and high temperature resistance
The invention belongs to the field of preparation processes of nano-porous materials, and particularly relates to a preparation method of high-emissivity high-temperature-resistant silicate high-entropy aerogel. The high-entropy silicate aerogel material with excellent high-temperature stability is prepared by utilizing a relatively simple sol-gel method, and the material is expected to meet the requirements in the fields of aerospace, civil kilns and the like at present. Meanwhile, the simple preparation method of the high-entropy silicate aerogel is favorable for promoting the development of aerogel industrialization, and solves the problems that the preparation cost of the existing high-entropy aerogel is high, high temperature resistance and high emission are difficult to integrate and the like.
本发明属于纳米多孔材料的制备工艺领域，具体涉及一种高发射率耐高温硅酸盐高熵气凝胶的制备方法。本发明利用较简单的溶胶‑凝胶方法制备优异的高温稳定性的高熵硅酸盐气凝胶材料，该材料有望满足目前航空航天、民用窑炉等领域的需求。同时，该高熵硅酸盐气凝胶的简易制备方法的提出有利于推动气凝胶产业化的发展，解决目前高熵气凝胶制备成本高、耐高温与高发射难兼具等问题。
