MOLDING HEAT INSULATING MATERIAL AND METHOD FOR MANUFACTURING THE SAME
To provide a molding heat insulating material which can suppress degradation of inside of a heat insulating material by permeation of gas and is suitable for a high-frequency induction heating type furnace.SOLUTION: A method for manufacturing a molding heat insulating material includes: an impregnation step of impregnating at least one surface of a molding heat insulating material having a protective carbon layer composed of a carbon fiber felt formed by entangling carbon fibers and a carbonaceous material coating a surface of the carbon fibers of the carbon fiber felt with a surface coating liquid obtained by dispersion of an aggregate of a carbonaceous material and thermosetting resin particles having a softening point in a dispersion medium not dissolved with the thermosetting resin particles; a softening step of softening the thermosetting resin particles by heating to a temperature equal to or higher than the softening point, and fixing the aggregate of the carbonaceous material to the molding heat insulating material, after the impregnation step; and a baking step of carbonizing the thermosetting resin particles by baking at 500°C or higher, after the softening step.SELECTED DRAWING: Figure 1
【課題】ガスの浸透による断熱材内部の劣化を抑制し得た、しかも高周波誘導加熱方式の炉に適した成形断熱材を提供する。【解決手段】炭素繊維を交絡させた炭素繊維フェルトと前記炭素繊維フェルトの炭素繊維表面を被覆する炭素質からなる保護炭素層とを有する成形断熱材の少なくとも一つの表面に、炭素質の骨材と、軟化点を有する熱硬化性樹脂粒子とが、前記熱硬化性樹脂粒子が溶解しない分散媒中に分散された表面被覆液を含浸させる含浸ステップと、前記含浸ステップの後、前記軟化点以上の温度に加熱して前記熱硬化性樹脂粒子を軟化させて前記炭素質の骨材を前記成形断熱材に固定する軟化ステップと、前記軟化ステップの後、５００℃以上で焼成して前記熱硬化性樹脂粒子を炭素化させる焼成ステップと、を備える成形断熱材の製造方法。【選択図】図１
