Development of a Fire-Extinguishing Wallpaper Containing Microcapsules

In this study, a wallpaper with fire-extinguishing properties was developed. This wallpaper is expected to increase the evacuation time and suppress the spread of flames in case of fire. It was confirmed that the fire-extinguishing time of an ordinary wallpaper can be increased from 2 to 5 min by incorporating micro-extinguishing capsules in the general water pool. After attaching microfire-extinguishing capsules in the form of a film on the back of the wallpaper, a burning test using a torch and 45° flame retardant digestion was performed, and the thermal properties of the adhesive film were verified based on the reaction start temperature, peak point, reaction end temperature, and weight reduction rate through thermogravimetric analysis.
