摘要: 使用锥形量热仪研究汽车典型门板材料(聚丙烯蜂窝板填料/包覆层组合件)在15、25、35、45 kW/m2热辐射功率条件下的点燃时间、热释放速率及热释放总量等特性参数。引入火灾性能指数、火灾增长指数,利用Petrella评价体系分析各组合件的火灾危险性。结果表明,PP-PVC较难被点燃,具有高火灾性能指数和低火灾增长指数,PP-PVC组合件火灾危险性较低。

Abstract:  The cone calorimeter was used to study the ignition time, heat release rate and total heat release of the typical car door materials (Polypropylene honeycomb board packing/cladding assembly) under different heat fluxes of 15, 25, 35, 45 kW/m2. By introducing fire performance index (FPI) and fire growth index (FGI),using Petrella evaluation system, the fire hazard of assemblies was compared and analyzed. The results showed that the PP-PVC is difficult to be ignited, with high fire performance index and low fire growth index, so the PP-PVC assembly has lower fire hazard.

Key words: cone calorimeter, car door plank, combustion characteristic, fire hazard
