阻燃预警智能涂层的研究进展

Research progress of intelligent flame retardant coating with fire-warning capabilities

随着城市化进展的加快和高层建筑的增加,传统材料阻燃处理手段已无法满足消防安全需求,需要额外引入火灾预警系统。当今主流的商业火灾预警系统与建筑材料分离,往往需要较长时间才能实现预警,无法为火灾的及时扑救和人员撤离提供最佳时间,而实现火灾超早期预警的关键在于将火灾传感器与基体紧密结合。智能涂层是一种人造的、能够对外部刺激有选择地提供最佳反应的涂层系统。将智能涂层引入传统建材领域,赋予各种材料阻燃预警响应功能,使其在使用过程中主动对外界"火灾"做出反应,将极大程度提高建筑的可靠性,对保障人员的生命及财产安全具有重大研究意义。本文综述并讨论了近年来阻燃预警涂层的火灾响应机制、构筑策略及目前的研究现状,展望了该领域的发展和应用前景。

With the rapid development of urbanization and the increase of high-rise buildings,traditional fire-retardant materials are unable to meet the fire safety needs,additional fire warning system is required.However,today’s dominate commercial fire warning system is separated from building materials and thus need a long time to activate the alarm system,which wastes the best time for firefighting and evacuation.The key to realize super early fire warning is closely integrating the fire warning system and the matrix.Intelligent coating is a kind of artificial coating system that selectively provides the best response to external stimulus.By introducing intelligent coating into the traditional building fields,giving different kinds of materials flame retardant coating with fire-warning capabilities could make them actively respond to the external"fire"in the usage process,which would greatly improve the reliability of buildings,safety of life and their property safety as well.This paper summarizes and discusses the fire response mechanism,construction strategy and current research progress of flame retardant coating with fire-warning capabilities in recent years,and prospects future development and applications of this field.
