Fire Retardancy of Modified Cryptomeria Fortunei Wood
We evaluated the fire retardancy effect on Cryptomeria Fortunei wood treated with melamine-urea-formaldehyde(MUF)resin mixed with boric acid and borax under different concentrations.The results showed that oxygen index,ignition time(TTI)and residue mass all increased and heat release rate(HRR),total heat release(THR),CO2 and CO concentration all decreased.Therefore,we concluded that the fire retardancy of the treated samples was much improved.
