Abstract: In this paper, the modified phenolic foam with better structure was prepared by sol-gel method, which combined nano phenolic foam (PF) with tetraethyl orthosilicate (TEOS), and vacuum impregnation technology. The properties of the modified phenolic foam were analysed comprehensively, and the micro morphology, physical and chemical properties of the modified phenolic foam were studied by means of differential thermal analysis (DTA) and thermogravimetric analysis (TGA), X-ray electron diffraction and other instruments. The ablation test showed that the mass ablation rate and linear ablation rate of TEOS composite with 3% hydrogen chloride as catalyst were the lowest, which were 0.022 g/s and 0.0272 mm/s, respectively. This proved that the nano composite modified phenolic foam material prepared in this paper has excellent performance and can be used in the design of building exterior walls, furniture, etc.

Keywords: nanocomposite building materials; phenolic foam materials; composite modified materials; architectural design; performance research.
