Fiber-reinforced high-temperature-resistant heat-radiation-proof composite aerogel and preparation process thereof
The invention discloses fiber-reinforced high-temperature-resistant heat-radiation-proof composite aerogel and a preparation process thereof. The fiber-reinforced high-temperature-resistant heat-radiation-proof composite aerogel is prepared from the following raw material components: 10 to 20 parts of a silicon source, 2 to 80 parts of an organic solvent, 1 to 40 parts of water, 0.01 to 10 parts of a catalyst, 3 to 10 parts of polydimethylsiloxane, 0.1 to 3 parts of tetraethoxysilane, 0.5 to 3 parts of nano microporous aluminum oxide, 0.5 to 3 parts of nano ceramic microspheres, 0.5 to 4 parts of titanium dioxide, 0.5 to 4 parts of ferroferric oxide and 1 part of a fiber skeleton. The preparation method is low in cost, simple in procedure, easy to operate, mild in reaction condition, stable in yield and capable of achieving large-scale production, and the prepared aerogel composite material can achieve the following technical effects that compared with existing silicon dioxide aerogel in the market, the aerogel composite material can tolerate 1200 DEG C, meets the high-temperature using condition under special conditions and has a good heat insulation effect.
本发明公开了一种纤维增强耐高温防热辐射复合气凝胶及其制备工艺，该纤维增强耐高温防热辐射复合气凝胶包括以下原料组份：硅源10‑20份、有机溶剂2‑80份、水1‑40份、催化剂0.01‑10份、聚二甲基硅氧烷3‑10份、正硅酸乙酯0.1‑3份、纳米微孔氧化铝0.5‑3份、纳米陶瓷微球0.5‑3份、二氧化钛0.5‑4份、四氧化三铁0.5‑4份及纤维骨架1份。本发明成本低、工序简单易操作、反应条件温和、产率稳定，可以规模化生产，且制得的气凝胶复合材料可以达到以下技术效果，与市场现有的二氧化硅气凝胶相比，可以耐受1200℃，满足特殊情况下的高温使用条件，起到良好的隔热效果。
