| 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 nano- composite 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.
