摘要：
The effect of organic modified montmorillonite (OMMT) on the ablative property, fire retardancy, thermal stability and charring capability of the ethylene propylene diene rubber (EPDM) composite was studied. Experimental data show that 33% decrease in the linear ablation rate of EPDM composite was obtained at a loading of 2.5 wt-% OMMT, and the peak heat release rate of EPDM composite in the middle stage of a cone calorimeter (CONE) combustion was also decreased. It is mainly attributed to the formation of char residue during combustion of EPDM composites at high temperature as revealed by scanning electron microscopy and CONE tests. It is worth noting that char formed during the ablation of EPDM composites containing 2.5% OMMT gave better structural stability and thermal stability.
