Current Advances in Flame-Retardant Performance of Tunnel Intumescent Fireproof Coatings: A Review
Source abstract
Abstract
As building safety standards keep escalating, research on intumescent fireproof coatings has garnered growing attention. Among them, tunnels, with their enclosed configuration and relatively high accident occurrence rate, impose higher demands on the environmental friendliness, durability, and thermal stability of fireproof coatings. At present, intumescent fireproof coatings have been extensively applied in tunnels; however, a comprehensive and in-depth overview of intumescent fireproof coatings and their application in tunnels is still lacking. This paper summarizes the fire prevention mechanism of intumescent fireproof coatings, the intumescent fireproof system, the impact of functional fillers on the fire resistance performance of intumescent fireproof coatings, and the application of intumescent fireproof coatings in tunnels. Additionally, we present the synergistic effect of the combined use of different functional fillers. Finally, some key challenges regarding the use of intumescent fireproof coatings in tunnel environments are put forward, along with prospects and opportunities.
