摘要
建筑外墙保温材料作为建筑节能的主要材料之一,在建筑行业得到广泛应用。为研究3种典型建筑外墙保温材料的燃烧特性及火蔓延行为,在低压低氧试验舱分别对EPS、XPS及硬PU 3种典型建筑外墙保温材料开展水平贴壁火蔓延试验。通过对质量损失速率、火焰温度、辐射热等火灾参数进行分析,建立建筑外墙保温材料燃烧及火蔓延模型,研究结果有助于典型外墙保温材料的合理使用及阻燃处理。
As one of building energy saving materials,the building exterior wall insulation material is widely used in the construction industry.In order to study the combustion characteristics and fire spreading behavior of three kinds of building exterior wall insulation materials,the horizontal fire spreading experiments of XPS,EPS and rigid PU are carried out in a low-pressure and low-oxygen laboratory chamber.The differences of the three thermal insulation materials are analyzed from the parameters of mass loss rate,flame temperature and thermal radiation.The combustion and fire spread model of exterior wall insulation materials is established.The research results are helpful for the rational use and flame retardant treatment of typical exterior wall insulation materials.
