HEAT INSULATING MATERIAL AND MANUFACTURING METHOD THEREFOR
To provide a heat insulating material with a heat insulating layer, excellent not only in heat insulation but also heat resistance and compression resistance.SOLUTION: A heat insulating material 1 comprises a heat insulating layer 10 that has: a porous structure in which a plurality of particles are connected to form a skeleton, and which has pores inside, and has a hydrophobic site at least on the surface of the surface and the inside; a reinforcing fiber; and metal oxide nanoparticles as a binder. The heat insulating layer 10 has a mass weight loss rate of 10% or less in thermogravimetric analysis held at 500°C for 30 minutes.SELECTED DRAWING: Figure 1
【課題】 断熱性だけでなく耐熱性および耐圧縮性にも優れた断熱層を有する断熱材を提供する。【解決手段】断熱材１は、複数の粒子が連結して骨格をなし、内部に細孔を有し、表面および内部のうち少なくとも表面に疎水部位を有する多孔質構造体と、補強繊維と、バインダーとしての金属酸化物のナノ粒子と、を有する断熱層１０を備える。断熱層１０は、５００℃下で３０分間保持する熱重量分析における質量減量率が１０％以下である。【選択図】図１
