1.Introduction
Organic insulation materials are widely used in buildinginsulation system because of its excellent integrated performance.However,thebiggest shortcoming of these materials is flamma-bility.With the increasingapplication of these materials,more and more fires were caused,resulting ingreat economic and life loss,even serious social impact.The big fire occurredat China Central Television (CCTV) new site building,in February 9,2009,leaded to direct economic losses of 163.83 million RMB,due to the employ- mentof extruded polystyrene (XPS) as the building external wall insulationmaterial.Soon after that,in November 2010,another big fire at residentialhigh-rise in Shanghai Jing’an district caused 58 people killed and more than 70people injured.The investigations to these fire disasters showed thatcombustion caused by organic insulation material could quickly spread from thefire origin to the entire building.As a consequence,the degradation behaviorand products of such materials are thus significant to be studied.

1.导言
有机保温材料广泛应用于建筑保温系统因其优异的综合性能. 然而,这些材料的最大缺点是它的阻燃性能欠缺.随着这些材料的应用愈加广泛,所造成的火灾事故愈加频繁,导致巨大的经济损失和人身伤亡,甚至是恶劣的社会影响.2009 年 2 月 9 日,发生在中国北京中央电视台 （CCTV） 新楼建设工地的大火,源于该建筑物外墙保温用材料为挤出型聚苯乙烯阻燃性能欠缺,其直接经济损失高达 1.64 亿元人民币.21个月后,2010 年 11 月,上海静安区的高层住宅又发生一起特大火灾, 58 人死亡, 70多 人受伤.对数起火灾的调查结果显示,有机保温材料的燃烧可能从火源迅速漫延及整座建筑物.因此,对降解行为和这种材料产品的研究极有意义.
众多的研究者对各种聚合物的热降解进行了大量研究.这些研究结果表明,热降解始终是固体燃烧过程的初始步骤,然后释放出可燃性挥发物助燃.这项工作的目的是研究热降解特性和保温材料PU、 XPS和EPS的挥发性产物.
