摘　　要：对PVC壁纸、纸浆壁纸、低度发泡壁纸、阻燃壁纸和无纺壁纸五种市场常见壁纸进行燃点实验和热重分析实验,测得燃点依次为247、246、245、273、297℃,得到5种壁纸的TG曲线、DTG曲线以及DTA曲线。研究结果表明,阻燃壁纸的燃点相对较高,受热熔化并膨胀;无纺壁纸的主要热解阶段持续时间最短;除阻燃壁纸外的其余4种壁纸的主要成分约在500℃时完成热解。Conducted the experiment on ignition point and thermo gravimetric analysis on 5 kinds of common wallpaper including PVC wallpaper, pulp wallpaper, low foaming wallpaper, flame retardant wallpaper and non-woven wallpaper. From the experiment, the ignition points were 247, 246, 245, 273 and 297 ℃ respectively. The TG curve, DTG curve and DTA curve were obtained. The analysis of the experimental result indicates that the ignition point of the flame retardant wallpaper is relatively higher, will melt and expand when heated; the main pyrolysis of non-woven wallpaper is the shortest. The main components of the 4 kinds of wallpaper except flame retardant wallpaper complete their pyrolysis processes at about 500 ℃.
