Smoke Suppression Effects of LDH Nanomaterials for Epoxy Resin
Abstract:
EP/LDH composite materials were prepared by adding LDH(Layered Double Hydroxide) to epoxy resin(EP). Oxygen index and smoke density in condition of no flame combustion for EP/LDH composite materials were determined. The flame retardancy and smoke suppression effects of LDH nanomaterials on EP were investigated. Smoke suppression mechanism of LDH was discussed. The results showed that the oxygen index of EP has increased slightly, but the smoke suppression effect was remarkable when LDH was added in 20~60 parts per 100 parts of resin. It is suggested that the porous thermal decomposed products of LDH with large specific surface area give smoke suppression effects by adsorbing the smoke and gases produced in the course of combustion.
