Preparation method of low-cost fiber reinforced aerogel
The invention discloses a low-cost preparation method of fiber-reinforced aerogel, which comprises the following steps: S1) oxidizing nano-powder, and preparing a nano-powder aqueous solution; s2) soaking the porous material in the nanopowder aqueous solution, and performing ultrasonic vibration treatment to uniformly distribute the nanopowder in pores of the porous material; s3) drying and sintering the porous material subjected to ultrasonic soaking in a microwave drying oven; and S4) repeating the steps S2-S3 until the aerogel meeting the density requirement is obtained. According to the preparation method of the low-cost fiber-reinforced aerogel, provided by the invention, the fiber-reinforced aerogel has good toughness and mechanical strength which are not possessed by common aerogel, can be extruded, and does not crack or deform after being extruded; meanwhile, the composite material has extremely high corrosion resistance, heat insulation and sound insulation performance and unique air permeability, is low in manufacturing cost and can be produced on a large scale.
本发明公开了一种低成本的纤维增强气凝胶的制备方法，包括如下步骤：S1）对纳米粉末进行氧化，并制备纳米粉末水溶液；S2）将多孔材料浸泡在纳米粉末水溶液中，并进行超声振动处理，使得纳米粉末在多孔材料的孔隙中均匀分布；S3）将超声浸泡后的多孔材料放置在微波干燥箱内进行干燥和烧结；S4）重复步骤S2‑S3直至得到符合密度要求的气凝胶。本发明提供的低成本的纤维增强气凝胶的制备方法，具有普通气凝胶所不具备的良好韧性和机械强度，可挤压，挤压后不破裂，不变形；同时还具有极高的耐腐蚀、隔热、隔音性能和独特的透气性，且制造成本低，可大批量生产。
