摘要
综述了近年来聚氨酯硬质泡沫塑料/可膨胀石墨复合材料的阻燃研究进展,详细介绍了该泡沫复合材料的制备方法、热解性能以及燃烧性能(包括极限氧指数、水平/垂直燃烧速率、热释放速率、CO/CO2生成量比值、成炭性)。分析了泡沫密度、可膨胀石墨含量及粒径、微囊包覆处理以及与其他阻燃剂复配使用对相应泡沫复合材料热稳定性及阻燃性能的影响,并对相关机理进行了深入的探讨。
Recent research progress in flame retardancy of rigid polyurethane foam/expandable graphite composites was reviewed. A detailed introduction was given on its preparation method, thermal degradation behavior as well as flammability properties including limited oxygen index, horizontal and vertical burning rates, heat release rate, weight ratio of C0/C02 production, and carbonization performance. The influences of foam density, addition amount, particle sizes, encapsulation treatment of expandable graphite as well as the combination with other flame retardants on thermal stability and flammability of the foam composites were analyzed. Besides, the relative mechanism was discussed in depth.
