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 (AIBN), 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(THR) 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.
