Aerogel composite insulation board for building and preparation method of aerogel composite insulation board
The invention relates to the technical field of composite boards for buildings, in particular to an aerogel composite insulation board for buildings and a preparation method of the aerogel composite insulation board. The composite insulation board is sequentially formed by a supporting layer, an aerogel composite layer and a facing layer from inside to outside in a hot pressing and curing mode, the aerogel composite layer is an aerogel composite foaming layer formed by coating functionalized SiO2 aerogel through polyurethane in a cross-linking mode, and the functionalized SiO2 aerogel is prepared by grafting SiO2 aerogel through functionalized carbon fibers. The polyurethane and the SiO2 aerogel are combined in a chemical bond manner, and the functional carbon fiber plays a layer-pillar structure between the polyurethane and the SiO2 aerogel, so that the bonding property between the polyurethane and the SiO2 aerogel is improved, the volume shrinkage rate of the SiO2 aerogel is reduced, the pore collapse of the aerogel in the hot-pressing curing process is inhibited, and the thermal conductivity of the aerogel is improved. Meanwhile, a compact and uniform composite structure layer is formed, so that the SiO2 aerogel skeleton structure is more stable.
本发明涉及一种建筑用复合板技术领域，具体涉及一种建筑用气凝胶复合保温板及其制备方法。所述复合保温板由内到外依次为支撑层、气凝胶复合层和饰面层热压固化形成，所述气凝胶复合层是通过聚氨酯交联包覆功能化SiO2气凝胶形成的气凝胶复合发泡层，所述功能化SiO2气凝胶是通过功能化碳纤维接枝SiO2气凝胶制备而成。本发明通过聚氨酯和气凝胶通过化学键的方式结合，功能化碳纤维在聚氨酯和SiO2气凝胶之间起到了“层‑支柱”结构，提高了聚氨酯和气凝胶之间的结合性，低了SiO2气凝胶的体积收缩率，抑制热压固化过程中气凝胶的孔隙坍塌，同时形成致密均匀的复合结构层，使SiO2气凝胶骨架结构更加稳定。
