摘要：Oriented strand board (OSB), with its brick-and-mortar-like structure that imparts high strength and its distinct strand texture that offers aesthetic appeal, has been widely applied in construction and furniture. However, its intrinsic flammability restricts broader use, while conventional flame-retardant coatings often compromise environmental compatibility and transparency. In this study, a fully bio-based intumescent flame retardant was synthesized from phytic acid, chitosan, and an alpha-amino acid, and applied as a transparent surface coating on OSB to simultaneously enhance fire safety and preserve natural aesthetics. The treated OSB exhibited a 31.1 % reduction in peak heat release rate and a 54.2 % decrease in total smoke production compared with untreated OSB. Single-chamber tests further showed that concentrations of HCN, HCl, and CO decreased by 36.9 %, 38.8 %, and 34.7 %, respectively, while smoke suppression significantly outperformed conventional intumescent systems. This work demonstrates a sustainable and efficient flame-retardant strategy, offering valuable insights for the green design of wood-based materials and strong potential for engineering applications in safe, eco-friendly construction and furniture manufacturing.
