Aerogel anti-corrosion heat-insulation flexible plate and manufacturing method thereof
The invention relates to the field of anti-corrosion heat-insulation plate manufacturing, and provides an aerogel anti-corrosion heat-insulation flexible plate and a manufacturing method thereof. The aerogel anti-corrosion heat-insulation flexible plate comprises a core layer and composite layers arranged on the two sides of the core layer, wherein each composite layer comprises a heat conduction layer and an aerogel felt layer, and the heat conduction layers and the aerogel felt layers are sequentially arranged in a direction away from the core layer. A method for preparing the aerogel felt layer comprises following steps: mixing and dissolving nanometer silicon dioxide aerogel powder and polyurethane powder in a solvent, and carrying out stirring to obtain a soaking solution; soaking an aluminum silicate ceramic fiber felt into the soaking solution so as to allow nanometer silicon dioxide aerogel powder particles and polyurethane powder particles to be soaked into the aluminum silicate ceramic fiber felt, then taking out the aluminum silicate ceramic fiber felt, and conducting drying at 50-80 DEG C for 20-60 minutes; and after hot pressing is conducted for 15-50 min under the conditions of 80-120 DEG C and 3-10 MP, conducting cooling to normal temperature, keeping the pressure, and conducting continuous pressing for 8-24 h for forming. The aerogel anti-corrosion heat-insulation flexible plate provided by the invention is suitable for various application scenes, and is high in anti-corrosion and heat-insulation efficiency and high in practicability.
本发明涉及防腐绝热板制造领域，提供了一种气凝胶防腐隔热柔性板及其制作方法。该气凝胶防腐隔热柔性板包括芯层及设于芯层两侧的复合层，复合层包括导热层和气凝胶毡层，导热层和气凝胶毡层依次沿着远离芯层的方向设置；气凝胶毡层通过如下方法制得：将纳米二氧化硅气凝胶粉末与聚氨酯粉末混溶于溶剂中，搅拌后得到浸泡液；将硅酸铝陶瓷纤维毡浸入该浸泡液中以使纳米二氧化硅气凝胶粉末颗粒和聚氨酯粉末颗粒浸入该硅酸铝陶瓷纤维毡中，然后取出硅酸铝陶瓷纤维毡，于50~80℃下干燥20~60min；在80~120℃、3~10MP条件下热压15~50min后，冷却至常温并保持压力持续压制8~24h成型。本发明提供的气凝胶防腐隔热柔性板能够适用于各种应用场景，防腐隔热效率高、实用性强。
