Analysis on the Combustion Performance of the MMFU-Boric Acid/Borax Treated Poplar Wood

Abstract:

In this study, Melamine-methanol-formaldehyde-urea (MMFU) resin and the mixture of MMFU/boric acid/borax (MBB) were used as the modification solutions to impregnate wood from poplar plantation. The combustion performance of the wood before and after impregnation treatment was investigated by using the oxygen index apparatus and cone calorimeter. Results showed that the oxygen index of the MMFU and MBB treated wood both increased. Compared with the untreated wood, the MMFU and MBB treatment significantly delayed the ignition time and the appearance of peak value of the heat release rate (HRR) during the combustion. The MMFU and MBB treatment also reduced the heat release rate (HRR), total heat release (THR), mass loss rate (MLR), generation rate of carbon monoxide (GCO) as well as total smoke release (TSR) significantly. Both MMFU and MBB exhibited good effect of smoke suppression on wood, while MBB had better flame retardancy than MMFU. Boric acid/borax exerted excellent synergistic effect of fire resistance on MMFU.
