SURFACE-TREATED MOLDED HEAT INSULATOR AND METHOD FOR PRODUCING THE SAME
PROBLEM TO BE SOLVED: To provide a long-life molded heat insulator at a low cost, which could be suppressed from deterioration and powdering.SOLUTION: Provided is a method for producing a surface-treated molded heat insulator, comprising: an immersion step where at least one surface of a molded heat insulator, having a fiber felt interlaced with carbon fibers and a protective carbon layer comprising a carbonaceous material which coats surfaces of the carbon fibers in the fiber felt, is immersed in a solution of a surface coating agent comprising a synthetic resin which is carbonized by a heat treatment and a solvent which dissolves the synthetic resin to add the surface coating agent-containing solution to the molded heat insulator; and a heat treatment step where, after the immersion step, the molded heat insulator is heat treated at 1500 to 2500°C under an inert atmosphere to form a surface coating layer by carbonizing the synthetic resin.SELECTED DRAWING: Figure 1
【課題】劣化や粉化を抑制し得た長寿命な成形断熱材を低コストで提供する。【解決手段】炭素繊維を交絡させた繊維フェルトと前記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を、熱処理により炭素化する合成樹脂と前記合成樹脂を溶解する溶媒とからなる表面被覆剤溶液に浸漬して、成形断熱材に前記表面被覆剤溶液を添加する浸漬ステップと、前記浸漬ステップ後、成形断熱材を不活性雰囲気下１５００〜２５００℃で熱処理し、前記合成樹脂を炭素化させて、表面被覆層を形成する熱処理ステップと、を有する表面処理された成形断熱材の製造方法。【選択図】図１
