摘要: 采用锥形量热仪实验对涤纶面料丙纶玻璃纤维板、涤纶面料丙纶麻纤维板和 PVC 革丙纶麻纤维板 3 种典型汽车内饰材料在 25、35、50 kW/m2 热辐射强度下的点燃时间、质量损失率、热释放速率等燃烧特性参数进行研究,并选取点燃预测模型计算材料的临界热辐射强度,使用轰燃倾向指数和热释放总量评价其潜在火灾危险性。结果表明,在实验热辐射强度下,涤纶面料丙纶麻纤维板质量损失百分率最大,结构完整性最差;涤纶面料丙纶玻璃纤维板平均点燃时间最短,临界热辐射强度最小,最容易被引燃;PVC 革丙纶麻纤维板热释放速率峰值最大,火灾性能指数最小,发生轰燃的可能性最大。

Abstract: Combustion characteristics of polyester fabric polypropylene fiberglass board, polyester fabric polypropylene hemp fiber board and PVC leather polypropylene hemp fiber board were experimentally investigated under radiation heat flux of 25, 35, 50 kW/m2 by cone calorimeter, such as the ignition time, mass loss percentage and heat release rate, etc. The ignition prediction model was selected to calculate the critical thermal radiation intensity of these materials. Flashover tendency index and total heat release were adopted to evaluate their potential fire hazard. The results showed that the mass loss percentage of polyester fabric polypropylene hemp fiber board is the maximum, and the structural integrity is the worst correspondingly under the experimental radiation heat flux. The average ignition time of polyester fabric polypropylene fiberglass board is the minimum as well as the critical thermal radiation intensity, it is most likely to be ignited. The peak heat release rate of PVC leather polypropylene hemp fiber board is the highest, and the probability of flashover presents the greatest due to the lowest fire performance index.
