PBO fiber product composite aerogel high-performance thermal insulation material and preparation method thereof
The invention discloses a PBO fiber product composite aerogel high-performance thermal insulation material and a preparation method thereof, and belongs to the technical field of processing of high-performance thermal insulation materials. PBO fiber paper and felt of certain thickness are used as a reinforced base material; and in a sol-gel process for preparing aerogel, sol and the reinforced base material are compounded in a dip coating mode, and the high-performance thermal insulation material is prepared through gelation, aging and ethanol supercritical drying. The high-performance thermal insulation material prepared by the invention not only retains the advantages of high strength, high heat resistance, super flame retardance and the like of a PBO fiber product, but also has the excellent thermal insulation performance of aerogel, so that the advantages of the material are greatly expanded, and the application range and the use value of the material are improved.
本发明公开了一种PBO纤维制品复合气凝胶高性能隔热材料及其制备方法，属高性能隔热材料的加工技术领域，具体实施方式为：以一定厚度的PBO纤维纸、毡作为增强基材，在制备气凝胶的溶胶‑凝胶工艺过程中将溶胶与增强基材采用浸渍涂布方式进行复合，经凝胶、老化、乙醇超临界干燥制成高性能隔热材料。本发明制备的高性能隔热材料不仅保留了PBO纤维制品的高强度、高耐热性和超阻燃性等优点，而且兼具了气凝胶的优异隔热保温性能，大大扩展了该材料的优点，提升了该材料的应用范围和使用价值。
