NSCFR flame retardant is one of key factors of non-smoke combustible wood-based materials.Thermal analysis,cone calorimetry,Py-GC/MS, scanning electron microscopy(SEM) were utilized to investigate the flame-retardation and smoke-suppression characteristics and mechanisms of NSCFR flame-retardant.The results show that NSCFR flame-retardant could significantly shorten the combustion duration of wood-based materials and completely eliminate the second peak of heat release rate curve,greatly reduce heat release rate, total smoke release,mass loss rate,specific extinction area,and carbon monoxide p...
