文摘

The zinc hydroxystannate/reduction graphene oxide (ZHS/RGO) hybrid was successfully prepared through the hydrothermal route, and its structure, composition and thermal properties were confirmed by XRD, FTIR, XPS, SEM, TEM, Raman spectra, and TG. ZHS/RGO hybrid is multilayer sandwich structure by morphological characterization. ZHS/RGO was applied to reduce fire hazards of epoxy (EP) as a flame retardant and smoke suppressant. The incorporation of 3.0 mass% ZHS/RGO provided fire-retardant properties to epoxy resin, testified by the results of cone calorimetry. The results indicated that ZHS/RGO can suppress the formation of smoke and toxic carbon monoxide as well as enhance the flame retardancy of the EP composites. The heat release rate, total heat release, smoke production rate, and total smoke production of EP-ZHS/RGO were greatly decreased compared with the pure EP. During the combustion process, ZHS/RGO may exhibit gaseous phase effect and condensed phase effect.
