性がない。Conventional heat-resistant sound-absorbing insulation materials include asbestos, rock wool, short glass fibers,
There are cotton-like inorganic short fibers such as ceramic fibers (mainly composed of alumina and silica), and products molded with synthetic resins such as phenol resin or some inorganic binders. The heat resistance of these materials is low, and they burn while emitting toxic gases at around 150°C, causing deformation and lack of dimensional stability.
又無機系結合剤は高価で、かつ結合力が弱いため可燃性
の合成樹脂を混和しているものが多く、成型品が硬直で
通気性なく吸音材として適用できない。In addition, inorganic binders are expensive and have a weak bonding force, so many of them are mixed with flammable synthetic resins, and the molded products are rigid and have no air permeability, making them unsuitable for use as sound absorbing materials.
