Preparation method of phenolic aerogel composite heat insulation tile
The invention provides a preparation method of a phenolic aerogel composite heat insulation tile, and belongs to the field of heat insulation tiles. The preparation method of the phenolic aerogel composite heat insulation tile comprises the following steps: preparing the outer-layer forming body, preparing the modified reinforced fibers, preparing the composite forming body, preparing impregnation liquid, and impregnating and sizing. According to the preparation method of the phenolic aerogel composite heat insulation tile, the bonding performance of a fiber skeleton and a phenolic resin material can be effectively improved while the brittleness of the material is improved, brittle fracture is avoided, and the high-temperature protection durability is improved; the thermal stress problem of the heat insulation tile is effectively solved, the heat insulation tile is prevented from cracking or deforming in the rapid temperature changing process, and the mechanical property and the heat insulation performance of the heat insulation tile are further improved.
本发明提供一种酚醛气凝胶复合隔热瓦的制备方法，属于隔热瓦领域。所述酚醛气凝胶复合隔热瓦的制备方法，由以下步骤组成：制备外层成型体、制备改性增强纤维、制备复合成型体、制备浸渍液、浸渍定型。本发明的酚醛气凝胶复合隔热瓦的制备方法，能够在改善材料脆性，避免脆性断裂，并提高高温防护耐久性的同时，有效提高纤维骨架与酚醛树脂材料的结合性能；有效降低隔热瓦存在的热应力问题，避免隔热瓦在快速变温过程中产生裂纹或变形，并进一步提高隔热瓦的力学性能及隔热性能。
