在建筑节能法规和政策的推动下,我国建筑节能工作获得了长足的发展。作为建筑节能关键支撑技术的外墙外保温技术得以迅速发展。目前,建筑外保温常用的保温材料主要有EPS模塑聚苯板、XPS挤塑聚苯板、PU/PIR聚氨酯保温板等,这些材料保温效果好,但是防火等级低、易燃,极易引发建筑火灾。最为突出的是,2009年2月9日的央视新址北配楼火灾事故,2010年11月15日上海静安区教师公寓火灾, In the building energy-saving regulations and policies, driven by China’s building energy-saving work has made considerable development. As the key support technology of building energy-saving exterior insulation technology has been rapidly developed. At present, the insulation materials commonly used in building insulation are EPS molded polystyrene board, XPS extruded polystyrene board, PU / PIR polyurethane insulation board, these materials have good insulation effect, but the fire rating is low, flammable, easily lead to Building fire. Most prominent is the February 9, 2009 CCTV new site North Building fire accident, November 15, 2010 Shanghai Jing’an District, teacher apartment fire,
