外墙外保温系统的防火安全性分析

Fire-proof Safety Analysis on Outer-wall External Thermal Insulation System

本文首先对外墙外保温系统防火安全性问题的起因和防火性要求进行了分析,并对外保温用有机可燃保温材料的试验与评定予以论述。而后提出不宜不惜代价地提高有机保温材料的阻燃性能来提高外保温系统的防火安全性,而应重点考虑系统整体构造的防火性能,其中主要包括空腔、防火隔断和防火保护面层3个关键要素。

This paper firstly analyzed the fire causes and fire-proof requirements for outer-wall external thermal insulation systems, and then described the test of flammable organic thermal insulating materials. Although it was a very important method to improve the fire-proof safety of external thermal insulation systems by improving the non-combustibility of organic materials, the fire-proof capability of the whole system conformation which includes cavum, fire-proof separateness and fire-proof protecting layer should be importantly considered.
