The Application of Exterior Wall Insulation Materials in Fire Prevention in Construction Projects

摘要:

随着建筑节能标准的不断提高,有机类外墙保温材料凭借优异的保温性能得到广泛应用,但其潜在的火灾风险也给建筑安全带来了严峻考验。基于此,文章首先系统探讨了此类材料在防火应用中的现状、关键技术与发展趋势,梳理了国内外主要材料在燃烧性能分级及火灾行为机理方面的研究进展;其次通过搭建实验模型,对不同材料的火焰蔓延抑制效果进行了对比验证;最后,结合典型案例分析与数值模拟,进一步揭示了提升外墙外保温系统整体防火性能的综合策略,以期为类似工程提供参考。

Abstract:

With the continuous improvement of building energy-saving standards, organic exterior wall insulation materials have been widely used due to their excellent insulation performance. However, their potential fire risks also pose a severe test to building safety. Based on this, the article first systematically explores the current status, key technologies, and development trends of such materials in fire prevention applications, and summarizes the research progress of major materials at home and abroad in terms of combustion performance grading and fire behavior mechanisms. Secondly, by building experimental models, the flame spread suppression effects of different materials were compared and verified. Finally, by combining typical case analysis and numerical simulation, a comprehensive strategy for improving the overall fire performance of external wall insulation systems was further revealed, in order to provide reference for similar projects.
