MOLDED HEAT INSULATING MATERIAL WITH SURFACE LAYER AND MANUFACTURING METHOD THEREOF
To provide a long-life and inexpensive molded heat insulating material with a surface layer capable of suppressing deterioration of heat insulating performance due to gas.SOLUTION: A molded heat insulating material with a surface layer has a carbon fiber-based molded heat insulating material, an expanded graphite sheet laminated on the carbon fiber-based molded heat insulating material, and a sheet protective layer laminated in contact with the expanded graphite sheet. The sheet protective layer has a carbon fiber cloth, carbon particles, and a carbonaceous matrix covering the surfaces of the carbon fibers and the carbon particles of the carbon fiber cloth, where its bulk density is 0.5-2.0 g/cm3.SELECTED DRAWING: Figure 1
【課題】ガスによる断熱性能の低下を抑制し得た長寿命な表面層付き成形断熱材を低コストで提供する。【解決手段】炭素繊維系成形断熱材と、前記炭素繊維系成形断熱材に積層された膨張黒鉛シートと、前記膨張黒鉛シートに接して積層されたシート保護層と、を有する表面層付き成形断熱材であって、前記シート保護層は、炭素繊維クロスと、炭素粒子と、炭素繊維クロスの炭素繊維及び炭素粒子の表面を被覆する炭素質からなるマトリックスと、を有し、その嵩密度が０．５～２．０ｇ／ｃｍ３である、表面層付き成形断熱材。【選択図】図１
