| 摘 要： | 应用锥形量热仪研究了环氧树脂、酚醛树脂、EVA和PA6 4种塑料的燃烧裂解行为,得到了在不同辐射热流强度(25 kW.m-2、50 kW.m-27、5 kW.m-2)下材料的点燃时间、热释放速率、质量损失速率、燃烧剩余物的含量等燃烧性能参数,分析比较了不同塑料的燃烧裂解行为,实验结果发现,成炭性的材料在燃烧裂解过程中表现出了较低的可燃性。

| Abstract: | Burning and pyrolysis behaviors of some plastics including phenolic resin,epoxy resin,EVA and PA6 were studied using the cone calorimeter.The pyrolysis parameters including ignition time,heat release rate and mass loss rate were obtained and compared at different levels of incident heat fluxes.The morphology and structure of the char residues were examined by microscope.The results showed that the charring plastics displayed the low mass loss and lower flammability compared with non-charring plastics. |
