MDNs/FGNs协效阻燃环氧树脂复合材料的热降解动力学研究
Study on Thermal Degradation Kinetics of MDNs/FGNs Synergistic Flame Retardant Epoxy Resin Composites
摘要
Abstract
A thermogravimetric analyzer was used to study the thermal degradation processes of epoxy resin(EP),epoxy resin with intumescent flame retardant(EP/IFR),and epoxy resin with intumescent flame retardant combined with nanolayer molybdenum disulfide and flake graphite nanoplatelets(EP/IFR/MDNs/FGNs)composites.The effects of IFR and the synergistic action of MDNs/FGNs with IFR on the thermal stability and thermal degradation processes of EP were compared.The thermal degradation kinetics activation energies of the three materials were calculated using the Starink,Broido and Phadnis methods.The results showed that using MDNs/FGNs in conjunction with IFR enhanced the thermal stability of the materials,and significantly increased the char yield at 800℃.The activation energies calculated using the Starink method were 166.03,163.68,158.02 kJ/mol,the Broido method resulted in activation energies of 93.37,58.41,56.81 kJ/mol,and the activation energies obtained by the Phadnis method were 59.71,36.58,35.52 kJ/mol.The reaction mechanism functions were ultimately determined using the Phadnis method.关键词
