COATED INORGANIC FIBER POROUS BODY
To provide a coated inorganic fiber porous body which is suitable for use under a higher temperature because, even though inorganic fibers which constitute an inorganic porous body has good thermal resistance, thermal resistance of a binder such as a silane coupling agent and the like is limited.SOLUTION: The coated inorganic fiber porous body comprises: a porous body 1 containing inorganic fibers except asbestos; and a coating member 2 which coats at least a portion of a surface of the porous body. In the porous body, a content of the inorganic fibers relative to all inorganic components is 80 mass% or more, a content of the inorganic fiber and the coupling agent relative to the whole of the porous body is 95 mass% or more, a content of the organic binder is 0.5 mass% to 10 mass%, a bulk density of the porous body is 0.001 to 0.1 g/cm3, and an emissivity of the coating member is lower than an emissivity of the porous body. The coating member contains a metal and has an emissivity of 0.5 or less.SELECTED DRAWING: Figure 1
【課題】無機繊維多孔体を構成する無機繊維は耐熱性が良好であるが、シランカップリング剤等のバインダーの耐熱性には限界がある。さらに高温下での使用に適した被覆無機繊維多孔体を提供する。【解決手段】石綿を除く無機繊維を含む多孔体１と、前記多孔体の表面の少なくとも一部を被覆する被覆部材２と、を含み、前記多孔体は全無機成分中に対する前記無機繊維の含有率が８０質量％以上であり、前記多孔体全体に対する前記無機繊維及びカップリング剤の含有率が９５質量％以上であり、前記有機バインダーの含有量が０．５質量％以上１０質量％以下であり、前記多孔体の嵩密度が０．００１〜０．１ｇ／ｃｍ３であり、前記被覆部材の輻射率が前記多孔体の輻射率よりも低いことを特徴とする被覆無機繊維多孔体。前記被覆部材が金属を含み、輻射率が０．５以下である。【選択図】図１
