摘要：
Metal-organic frameworks (MOFs) rich in P and N elements were synthesized by simple reflux and solvothermal method and applied to the flame retardant application of epoxy resin (EP). The results of cone calorimeter test showed that the peak heat release rate, peak smoke release rate, peak CO production and peak CO2 production of EP-6 decreased by 49.97%, 23.53%, 43.24% and 60.11%, respectively, indicating that the calcined MOFs had higher flame retardant and smoke suppression efficiency. The flame retardant mechanism is attributed to the multi-synergistic properties among transition metal (Cu, CuO and Cu2O) in condensed phase and non-flammable gases (H2O, CO2 and NH3) in gas phase.
