摘要: 以聚(3,4-乙烯二氧噻吩)(PEDOT)修饰后的热电型石墨烯纳米片(TEG)和黏接剂(P(DPOP-Si))为原料,通过“涂覆-烘干”的方法在木材表面构筑具有火灾预警功能的阻燃纳米涂层,研究纳米涂层的火灾预警性能和阻燃性能,并对改性木材的阻燃预警机理进行探讨。目的是在低载荷量情况下赋予木材高效阻燃性能与早期火灾预警功能,扩大木材及木制品的应用领域。结果表明,改性木材(WOOD-3)的极限氧指数达到37.9%,热释放速率峰值和总热释放量相比纯木材分别降低了49.3%和47.3%。一旦发生火灾,纳米涂层在7 s内触发火灾警报,兼具较好的火灾预警性能和一定的阻燃性能。

Abstract: The PEDOT-modified thermoelectric graphene nanosheets (TEG) and adhesive (P(DPOP-Si)) are used as the raw materials to construct fire-retardant nano-coating with fire warning function on the surface of wood by the method of “coating-drying”, to study its fire warning performance and fire-retardant properties and to explore the fire-retardant warning mechanism of the coated wood. The objective of this study is to provide wood with efficient flame retardant properties and early fire warning function at low loading, so as to expand the application fields of wood and wood products. The results showed that the coated wood (WOOD-3) achieved a limiting oxygen index of 37.9%, and the peak heat release rate and total heat release were reduced by 49.3% and 47.3%, respectively, compared with pure wood. In case of fire, the nano-coating triggers the fire alarm within 7 s, which has both better fire warning performance and certain flame retardant properties.
