摘要
The NR/modified montmorillonite （EMT） nano-composites were prepared by mechanical mixing and reacting in situ with glycidyl methacrylate. Under 30 kW·m^-2 of heat flux, the combustion behavior of the nano-composites was studied with cone calorimetry, and PHRR, THR, EHC, TSR and MLR were tested. The results showed that the nanocomposite had improved mechanical properties and flame retardance properties, and to some extent, the nano-composite had smoke suppress effect. Compared with pure NR, the PHRR, EHC and SPR of the nano-composite reduced by 34%, 21% and 16.8%, respectively.
