摘要:该文利用氧指数测定仪、锥形量热仪测定了木纤维/回收塑料复合材料的燃烧性能,并与普通纤维板进行了对比.结果表明:①和普通纤维板相比,木纤维/回收聚氯乙烯复合材料从点燃时间和平均质量损失速率上表现为热稳定性很差,而热释放速率和平均有效燃烧热等性能较好;木纤维/回收聚丙烯复合材料热稳定性相对较好,但其他燃烧性能都表现很差;②回收聚丙烯和聚氯乙稀作为主要原料制备的木塑复合材料相比,前者热稳定性好,但总体表现为火灾危害性更大;③木纤维/回收聚丙烯复合材料在加入偶联剂PAPI后改变了的燃烧特性,表现为点燃时间延长、有效燃烧热降低、热释放速率提高.如将木塑复合材料用作室内建筑装饰材料,须考虑对其进行阻燃处理.
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.
