る。Further, the material for forming the heat insulating layer at the time of combustion is formed by adding foaming raw materials (raw material for fire reaction chemical reaction catalyst, raw material for carbon generation, raw material for non-combustible gas generation), color pigment, film forming resin and the like. It is a thing. Among these, the carbon-producing raw materials are selected from carbohydrates and polyhydric alcohols, and these are carbonized by contact with a flame to form a heat insulating layer. Further, the carbon-producing raw materials have an acid group and produce an inorganic acid and an ester, and the inorganic acid is phosphoric acid. This is generated by thermal decomposition of catalysts and fireproofing agents. Furthermore, as a non-combustible gas generating raw material, dicyandiamide, melamine,
You may mix paraffin chloride etc. Further, the fireproof coating layer 1 itself can be formed into a sheet.

The air is blocked and the air flow passage is blocked, so that it is possible to prevent air from being sent from the joints other than the fire through the hollow holes 2 and to prevent the toxic gas due to the fire from passing through the hollow holes 2. It is also possible to prevent it from flowing out to another joint.

分に流出させることがない。等の効果、特徴がある。As described above, according to the fireproof packing material of the present invention, since it is a dry type and has elasticity, it is easy to apply, and joints having heat resistance, waterproofness, stain resistance and weather resistance are also provided. Can be formed. The hollow holes formed inside allow air to flow, remove moisture from the refractory packing material, and keep it in a dry state at all times.
Fire resistance can be maintained for a long time. The hollow hole can be used as an expansion space for the refractory coating layer that expands due to heat in the event of a fire. When a fire occurs, the hollow pores are filled with the heat-resistant fire-resistant coating layer and the air flow path is blocked, so from the joints other than the area where the fire started,
Air can be prevented from being sent through the hollow hole, and toxic gas or the like due to fire will not flow out to another joint portion through the hollow hole. There are effects and features.
