Fire Retardant Performance of FRW treated larch-veneer polymer composite
To characterize the combustion behavior of wood-polymer composite (WPC),plain larch wood veneer (PLW),treated with or without fire-retardant FRW,was impregnated in the solution of monomer methyl methacrylate (MMA) and initiator azobisisobutyronitrile (A1BN),then heat-cured by the protection of nitrogen gas,and then analyzed by a cone calorimeter using PLW as control.The results showed that the heat and smoke release of the composites with and without FRW increased with the increase of the polymer loading;that compared to PLW the time to ignition(TTI) prolonged,the distribution region of heat release rate(HRR) of WPC broadened,the total heat release(THRi) increased and the smoke ratio(SR) increased;that the FRW treatment of PLW resulted in the significant fire retardation effects to the WPC,which caused decreases in the peak value of HRR,SR and THR.
