HIGH TEMPERATURE HEAT INSULATION MATERIAL
To provide a high temperature heat insulation material having excellent adiabaticity even in a high temperature region of 600°C or higher.SOLUTION: A high temperature heat insulation material is a molding containing: a base material made of an entangled aggregate of silica-based inorganic fibers having hydroxyl groups; and a silica cured material that exists at a surface layer of at least one side of the base material so as to adhere to the surface of the silica-based inorganic fibers or fill or crosslink the inter-fiber gaps of the silica-based fibers. The silica cured material is a dry solidified product of colloidal silica having an average particle size of 1 to 200 nm.SELECTED DRAWING: Figure 1
【課題】 ６００℃以上の高温領域でも優れた断熱性を有する高温用断熱材を提供する。【解決手段】 ヒドロキシル基を有するシリカ系無機繊維が交絡した集合体からなる基材、及び前記基材の少なくとも片側の面の表層部において前記シリカ系無機繊維表面に付着又は前記シリカ系繊維の繊維澗間隙を埋設ないし架橋するように存在しているシリカ硬化物を含む成形体であり、前記シリカ硬化物は、平均粒子径が１～２００ｎｍのコロイダルシリカの乾燥固化物である。【選択図】 図１
