Preparation method of fire-resistant double-layer fiber composite aerogel felt
The invention relates to a preparation method of a fire-resistant double-layer fiber composite aerogel felt, and relates to the technical field of fire-resistant materials. According to the preparation method disclosed by the invention, aerogel with relatively strong mechanical properties, relatively low density and excellent heat insulation capability is prepared by using double silicon sources, the aerogel is compounded with high-silica fibers to prepare a high-silica fiber aerogel felt, and finally, the high-silica fiber aerogel felt is compounded with a basalt fiber felt through a sewing process to prepare the double-layer fiber composite aerogel felt. The double-layer fiber composite aerogel felt is excellent in heat insulation, mechanical properties and the like.
本发明涉及一种抗火用双层纤维复合气凝胶毡的制备方法，涉及抗火材料技术领域。本发明使用双硅源制备具有较强力学性能、较低密度和优异隔热能力的气凝胶，并与高硅氧纤维进行复合制备高硅氧纤维气凝胶毡，最后通过缝纫工艺将其与玄武岩纤维毡进行复合制备出双层纤维复合气凝胶毡，该双层纤维复合气凝胶毡在隔热与力学性能等方面表现优异。
