Flammability properties of wood fiber-recycled plastic composite

Compared with normal fiberboard,flammability properties of wood fiber-recycled plastic composite were evaluated by cone calorimeter and oxygen index chamber in this article.Resutls were showed as the followings: 1) wood-PVC composite showed worse thermal stability on time to ignition(TTI) and mean heat release rate(MHRR),but better performance on heat release rate(HRR) and mean efficient heat of combustion(MEHC);wood-PP composite had better thermal stability properties,but was worse on other fire performance;2) Compared wood-PP composite with wood-PVC composite,the former showed excellent thermal stability,while behaved dangerous as a whole;3) Coupling agent PAPI changed fire performance of wood-PP composite and it showed longer time to ignition(TTI),lower EHC but higher HRR.It can be concluded that flame resistance treatment should be considered if wood-plastic composite is used as the decorated material.
