ス、臭素ガス等の有害ガスの発生がある。Although the heat insulating materials listed above have some performance, they have the following drawbacks. (1) Glass wool mat This is made from long glass fiber as a main raw material, is formed into a mat by a carding machine (carding machine), and is then needle punched. It is certified to have the same heat resistance and fire resistance of 30 minutes, but there is irritation (itching) to the skin of the glass fiber. (2) Foamed plastic This is a molded product obtained by foaming an organic plastic such as polyethylene, but it has problems such as easy breakage during molding, easy burning during a fire, and melting and dropping. (3) Inorganic material filling foam This is a plastic material with an inorganic filler and flame retardant added to improve flammability. It is certified as a quasi non-combustible equivalent to the Ministry of Construction and has a fire resistance of 30 minutes. Sometimes it melts and falls. Furthermore, harmful gases such as chlorine gas and bromine gas are generated due to the halogen-based flame retardant.

供することを目的としている。It is an object of the present invention to eliminate the hitting found in glass fibers, not burn easily like plastics, and not melt-fall in the event of fire or generate harmful gases like fires like inorganic material-filled foam. It is intended to provide a heat insulating material suitable for upholstery.

【課題を解決するための手段】本発明の第１発明による
断熱材は、珪酸含有レーヨン繊維が基材とされ、これが
ニードルパンチングにより所要厚さのマットに形成され
ていることを要旨としている。The heat insulating material according to the first aspect of the present invention is characterized in that a silicic acid-containing rayon fiber is used as a base material, which is formed into a mat having a required thickness by needle punching.
【０００６】また、本願の第２発明による断熱材は、前

ていることを要旨としている。The heat insulating material according to the second aspect of the present invention is characterized in that ammonium phosphate is added to the mat as a flame retardant.

い。The silicic acid-containing rayon fiber used as the base material of the heat insulating material of the present invention is a rayon fiber produced by the viscose rayon method and is produced by substituting 30 to 33% by weight of silicic acid or aluminum silicate. It is what is done. The silicic acid-containing rayon fiber has a LOI value (restricted oxygen concentration: minimum oxygen concentration required to continue combustion) of 28 to 33%.
Therefore, combustion does not continue in the atmosphere (oxygen concentration 20%).

められる。On the other hand, the silicic acid-containing rayon fiber is burned by another fire source flame, but since silica, alumina and unburned carbon remain as ash after burning, it retains strength and morphology. Therefore, the heat insulating material based on the silicic acid-containing rayon fiber according to the present invention is difficult to burn, and the strength and morphology remain after burning. Further, the flame retardancy is further enhanced in the case where the flame retardant such as ammonium phosphate is added.
