摘　　要：对汽车外饰所用材料的燃烧特性进行研究,从氧指数测试、锥形量热仪测试及垂直火蔓延试验等方面分析了试样的火灾危险特性。结果显示,实验材料在空气中容易点燃,并且燃烧剧烈;材料在有外界火源作用下,燃烧将更加迅速,热释放速率随外界热源功率的增加也有显著提升;外饰材料燃烧时具有明显的熔融、滴落现象。研究表明,汽车外饰材料具有非常高的火灾危险性。The combustion characteristics of car external decoration materials were analyzed with experiments,such as oxygen index test,cone calorimeter test and vertical fire spread test.The results show that sample materials discussed in this paper can be ignited easily in the air.The combustion behavior is violent.The sample can be heated by heated source and can catch fire in a short time.The higher the outside heat source is,the faster the material is ignited and the higher the heat release rate is obtained.The vertical fire spread tests show obvious melting and dripping phenomenon of the samples.As a result,car external decoration has high fire hazard.
