MOLDED HEAT INSULATING MATERIAL AND METHOD FOR PRODUCING THE SAME
PROBLEM TO BE SOLVED: To provide a molded heat insulating material in which degradation in inside of a heat insulating material caused by intrusion of gas can be suppressed.SOLUTION: A method for producing a molded heat insulating material includes: a step of immersing a region of at least 0.4 mm from at least one surface of a molded heat insulating material with a dense undercoat layer formation liquid containing an aggregate made of carbon and a binder made of a thermosetting resin, firing the dense undercoat layer formation liquid at 500°C or higher to carbonize a thermosetting resin and make the thermosetting resin formed into a dense undercoat layer; a step of immersing at least a part of a region of at least 0.1 mm from the surface of the dense undercoat layer with a surface coating liquid containing an aggregate containing a component to be a carbon particle and a binder made of a thermosetting resin after firing, then firing the surface coating liquid at 1,000°C or higher to carbonize the thermosetting resin and make the thermosetting resin formed into the surface coating layer, where a volume fraction of the aggregate in the dense undercoat layer is 0.3-5%, and a volume fraction of the aggregate in the surface coating layer is 1-7%.SELECTED DRAWING: Figure 2
【課題】ガスの浸透による断熱材内部の劣化を抑制し得た成形断熱材を提供する。【解決手段】炭素からなる骨材と熱硬化性樹脂からなる粘結剤とを含む緻密下地層形成液を、成形断熱材の少なくとも一つの表面から少なくとも０．４ｍｍの領域に含浸させ、その後５００℃以上で焼成して前記熱硬化性樹脂を炭素化させて緻密下地層となす緻密下地層形成ステップと、焼成後に炭素粒子となる成分を含んだ骨材と熱硬化性樹脂からなる粘結剤とを含む表面被覆液を、前記緻密下地層の表面から少なくとも０．１ｍｍの領域の少なくとも一部に含浸させ、その後１０００℃以上で焼成して、前記熱硬化性樹脂を炭素化させて表面被覆層となす表面被覆層形成ステップと、備え、前記緻密下地層における骨材の体積分率が、０．３〜５％であり、前記表面被覆層における骨材の体積分率が、１〜７％である、成形断熱材の製造方法。【選択図】図２
