Inorganic filled foams and the like are often used. The above-mentioned heat insulating materials have the following disadvantages. (1) Glass wool mat This is made from long glass fiber as the main raw material, formed into a mat shape by a carding machine (carding machine), and then needle punched into a product. The product is notified by the Ministry of Construction. It is certified as nonflammable, fire resistant for 30 minutes, but there is irritation (itching) of glass fiber to the skin, when bonding to metal plate, when bending into a folded plate shape (roll forming process), when roofing work Sometimes, glass fibers are scattered and attach or stick to the worker's skin, giving itching and severe irritation such as pain. (2) Foamed plastic This is a molded product obtained by foaming an organic plastic such as polyethylene, but has problems such as being easily cut during molding, easily burning in case of fire, and melting and falling. (3) Inorganic filler foam This is a plastic material to which an inorganic filler and a flame retardant have been added to improve the flammability. Melts and falls. In addition, harmful gases such as chlorine gas and bromine gas are generated due to halogen-based flame retardants.

る。SUMMARY OF THE INVENTION In view of the above problems, there is no etching found in glass fiber, it is not easily burned like plastic, and it melts and drops in the event of fire and generates harmful gas like inorganic filler foam. As a heat insulating material suitable for a metal-plated backing material having no metal, the present inventor has previously described in Japanese Patent Application No. 6-230497 a mat having a required thickness by using needle-punched rayon fiber containing silica as a base material. We have proposed a thermal insulation material for metal folded plate linings formed in Japan.

れる。The silica-containing rayon fiber used as the base material of the heat insulating material is a rayon fiber produced by a viscose rayon method and is produced by replacing 30 to 33% by weight of silicic acid or aluminum silicate. And has the following characteristics. (1) The silicic acid-containing rayon fiber has an LOI value (restricted oxygen concentration: the minimum oxygen concentration required to continue burning) of 28.
The combustion is not continued in the atmosphere (oxygen concentration: 20%). (2) The silicic acid-containing rayon fiber is burned by another flame source. However, even after burning, silica, alumina, and unburned carbon remain as ash, so that they retain strength and form. (3) Therefore, the heat insulating material based on the silicic acid-containing rayon fiber hardly burns, and its strength and form remain after burning.

There is a problem of doing.
