摘　　要：为探究玻璃纤维网对热固性、热塑性外墙保温材料燃烧性能的影响,采用锥型量热仪进行燃烧实验研究,并对燃烧产生的各项参数进行分析。结果表明,玻璃纤维网会增大保温板材的点燃时间、热释放速率、生烟速率等相关参数。热固性材料的部分火灾行为受玻璃纤维网的影响较为明显,但在引燃性和火灾传播性能方面所受影响较小。热塑性材料中,玻璃纤维网对于XPS的引燃性、释热性、火灾传播性能及EPS的生烟性影响较大。玻璃纤维网使PUF、EPS的火灾增长指数小幅度降低,有抑制火焰蔓延的作用。To investigate the effect of glass fibre mesh on the combustion performance of thermosetting and thermoplastic exterior wall insulation materials,a cone calorimeter was used to carry out combustion experimental studies and to analyze the parameters produced by combustion.The results show that the glass fibre mesh increases the ignition time,heat release rate,smoke generation rate and other relevant parameters of the insulation panels.Some of the fire behaviours of thermoset materials were more significantly affected by the glass fibre mesh,but less so in terms of ignitability and fire propagation properties.Among the thermoplastic materials,the glass fibre mesh has a greater influence on the ignitability,heat release,fire propagation properties of XPS and smoke generation of EPS.The glass fibre mesh reduces the fire growth index of PUF and EPS by a small amount and has the effect of inhibiting flame spread.
