NON-COMBUSTIBLE WOOD
To enhance non-combustibility of a non-combustible wood A in which a wooden substrate 1 is impregnated with a flame retardant agent, and to enhance workability while giving the taste of wood to the non-combustible wood A as a whole.SOLUTION: An adhesive agent 7 affixes a non-combustible paper sheet 5 on a rear surface of a wooden substrate 1 impregnated with a flame retardant agent in a laminated state and in an integral manner. In a case of fire, the non-combustible paper sheet 5 prevents the flame retardant agent within the wooden substrate 1 from blowing out from the rear surface as well as prevents the wooden substrate 1 from shrinking because of combustion, and causes a non-combustible wood A as a whole not to become shrunk, for preventing flame and high-temperature gas from passing through gaps and the like that have been made along the shrinking.SELECTED DRAWING: Figure 1
【課題】木質基材１に難燃化薬剤が含浸された不燃性木材Ａの不燃性を高めつつ、その不燃性木材Ａを全体として木材感があるものとし、その施工性を高めるようにする。【解決手段】難燃化薬剤が含浸された木質基材１の裏面に不燃紙５を接着剤７により積層状態で一体的に貼り付ける。火災の際に、木質基材１中の難燃化薬剤が裏面から噴き出すこと、及び木質基材１が燃焼により収縮することを不燃紙５によって抑制し、不燃性木材Ａは全体として収縮しないようにして、収縮に伴って生じた隙間等を火炎や高温ガスが通ることを防止する。【選択図】図１
