温度が上昇すると吸熱反応を起こす結晶水を持った物質
を用いて金庫内に内蔵する構造が知られている。Conventionally, the wall of a safe or the wall of a refractory structure is filled with foam material such as foamed concrete with low thermal conductivity, asbestos, etc., but it is necessary to set a large thickness in order to improve fire resistance or heat insulation performance. There was an unavoidable increase in size. Therefore, it is conceivable that a sealed water is built in between the wall materials such as concrete to slow down the heat conduction during heating, but this has been a long time due to the moisture permeability of the package that seals the water. There is a risk that the volume will gradually evaporate during the month and the capacity will decrease, and since it is difficult to replenish, an effective heat resistance effect cannot be achieved. Further, since it is a liquid at room temperature, it is troublesome to handle, and if the package is not strong, it is easily damaged. Further, there is a risk of explosion as vapor when high heat is applied while keeping hermetically sealed. Therefore, in Japanese Examined Patent Publication No. 45-5309 and Japanese Unexamined Patent Publication No. 54-78562,
There is known a structure in which a substance having water of crystallization that causes an endothermic reaction when the temperature rises is built in a safe.

When the gap (air layer) is formed, heat is easily conducted to the inside, and there is a drawback that fire resistance or heat insulation performance is deteriorated. This invention was created as a result of earnest research in view of the above circumstances, and its main problem is to store a chemical heat storage material in a package built in a fireproof structure so that a gap does not occur during liquefaction. Providing a refractory insulation structure.

途に応じた融点を有する物質を選択すればよい。In order to solve the above problems, the present invention provides (a). A package having a thermoplastic sealing portion that seals a hydrogen chloride-based chemical heat storage material and melts and opens at least a part of the water content of the chemical heat storage material before being vaporized by heating, a porous material having a water-absorbing property. A fireproof heat insulating material structure built in or abutting on the wall material of (b). Water and other solvents are added to the chemical heat storage material filled in the package and compressed, (c). A water absorbing material composed of powder, granules, or granules having a water absorbing property for a chemical heat storage material is added to the package to absorb the water or the water content of the solvent. (D). Thus, a technical measure is taken to reduce the gap between the package and the filling material as much as possible. Here, the hydrogen chloride-based chemical heat storage material, as long as it has low thermal conductivity, and needs a large number of calories when melting, for example, CaCl 2 · 6H 2 O, Na 2 SO 4 · 10H 2 O, Na
2 CO 3 · 10H 2 O, Na 2 HPO 4 · 12H 2 O, Ca (NO 3) 2 · 4H 2 O, Na

Mention may be made of KNO 3 -LiNO 3 -NaNO 3 and the like. These hydrogen chloride-based chemical heat storage materials are superior in heat of fusion per unit volume to chemical heat storage materials such as n-paraffin and its derivatives. Therefore, a substance having a melting point suitable for the heat resistant purpose may be selected from these hydrogen chloride chemical heat storage materials.

る。In the present invention, the hydrogen chloride-based chemical heat storage material melts and stores heat when heated to a temperature equal to or higher than a predetermined melting point during heating such as a fire. At this time, since a large amount of calories are required to dissolve the solid into a liquid (gel), conduction of heat transmitted inside is delayed. This gel-like chemical heat storage material is heated in the package, and the thermoplastic seal portion is melted at the temperature before the water content is vaporized by the heating to open the package. As a result, moisture is absorbed by the porous wall material having water absorption, so that the moisture is once cooled and the heat conduction is further delayed to improve fire resistance or heat insulation performance. In addition, since the gelled chemical heat storage material that is melted during heating is evenly filled in the package, no gap is formed between the package and the space in which the package is fitted, so it is uniform over the entire area. The heat resistance can be exerted.

もよい。Preferred embodiments of the present invention will be described below with reference to the drawings. The refractory insulation structure shown in Fig. 6 is sealed with a material that has no or low moisture permeability so that the moisture of the chemical heat storage material does not volatilize during normal times, and at the stage before the moisture evaporates after melting during heating. Seal part 7 that melts and opens at (temperature)
The chemical heat storage material 1 is sealed with a package 6 having In this embodiment, as the chemical heat storage material 1, sodium acetate hydrate (NaCH 3 COO · 3H 2 O) is used. The chemical heat storage material 1 is formed by heating a crystalline material once and molding it into a plate shape. The chemical heat storage material 1 is sealed by the packaging body 6 and built in or abutted on the wall material 2. Next, the wall material 2 may be, for example, foamed concrete or asbestos, as long as it is made of a porous material having water absorption property.
In this example, a molded plate (trade name: manufactured by Osaka Packing Manufacturing Co., Ltd., Taicalite Co., Ltd.) containing xonotlite-based calcium silicate hydrate as a main component is used. This calcium silicate hydrate molded plate is known as a strong fire-resistant heat insulating material and has a high heat insulating property (heat conductivity of 0.05% or less).
+ 0.00002θKcal / hr.m. ℃) and lightweight (specific gravity 0.2 to 0.45)
It is also excellent in water absorption. In addition, the material of the packaging body 6 has a structure in which aluminum foil is coated with tetoron flume, and after the chemical heat storage agent 1 is stored, the seal portion 7 has a vaporization point (58 ° C.) above the melting point (58 ° C.) of the chemical heat storage material 1. Ten
It is heat-sealed with a thermoplastic film that melts at a predetermined temperature (80 ° C. in this embodiment) below 0 ° C.). Therefore, in normal times, the moisture of the chemical heat storage material 1 hardly permeates from the package to the outside for a long period of time due to the nature of the material of the package 6, and can be stored in the original state, which is reliable. It is highly likely. Then, water or other solvent 8 is added to the chemical heat storage material filled in the package 6 to compress it to reduce (fill) the voids between the package 6 and the water-absorbing powder or granules as the water-supplying agent 9. A body, granules, or the like is added to absorb the water or the water content of the solvent and the gap between the package and the filling material is eliminated as much as possible. In this example, water was used as the solvent, and the water filler was the powder of ticalite forming the wall material 2 having excellent water absorption and low thermal conductivity. As a result, even when the chemical heat storage material 1 is a crystalline body, the gelled chemical heat storage material 1 melted at the time of heating is evenly filled in the packaging body 6, and the packaging bodies 6 to 6 are inserted. Since no gap is formed between the concave portion and the concave portion, it is possible to uniformly exert the heat resistance effect over the entire region. The distribution of the chemical heat storage material 1, the water or solvent 8 and the water absorbing agent 9 can be appropriately determined experimentally. Next, an embodiment in which the chemical heat storage material 1 built in the packaging body 6 having the above-mentioned configuration is built in the wall body will be described with reference to FIGS. 1 to 3 and 5. The refractory heat insulating material structure of FIG. 1 has a structure in which a recess 3 is provided in a wall member 2 and the chemical heat storage material 1 filled in the package 6 is fitted into the recess 3. The refractory insulation structure of FIG. 2 has a package 6 in the recess 3 of the wall material 2.
The chemical heat storage material 1 filled in is housed, the opening 3 ′ is sealed with the film 4, and the wall material 2 is superposed. The refractory insulation structure shown in FIG. 3 has a structure in which the chemical heat storage material 1 filled in the packaging body 6 is heated to be formed into a plate shape, which is filled in the packaging body 6 and superposed on the wall material 2. . FIG. 4 is a graph showing changes in the internal temperature. As shown in the graph, heat is transferred to the chemical heat storage material 1 having a low thermal conductivity through the wall material 2 having a low thermal conductivity, and the chemical heat storage material 1 Is 63ca as the latent heat of fusion when it exceeds the melting point (58 ° C in this example).
Since it requires l / g, it acts to lower the thermal conductivity. Further, when the chemical heat storage material 1 melts, it becomes a gel in the package 6. When the heating is further advanced and the seal portion 7 reaches 80 ° C., the package body 6 is opened and the gel-like chemical heat storage material 1 flows out, and its water content is absorbed by the wall material 1 in contact therewith. Since the wall material 1 which has absorbed the water is at a temperature higher than the temperature of the water, the temperature of the wall material 2 which has come into contact with it is lowered due to the absorbed water, and the water content of the gelled chemical heat storage material 1 is absorbed. Is absorbed by the wall material 2 and once the wall material 2
It also has the effect of lowering the temperature of, which also reduces the conduction of heat. Upon further heating, the water vaporizes while removing the heat of vaporization. As described above, according to the present invention, the time for allowing the wall material 2 to absorb the water content of the gelled chemical heat storage material 1 can be extended to a predetermined temperature, so that the optimum temperature for the slowest heat conduction can be set. It suffices to appropriately experimentally determine based on various conditions such as the purpose of use and other materials, and select a thermoplastic film that melts at that temperature and seal it as the seal portion 7 of the package 6. This fireproof heat insulating material structure can be widely used as a wall material of a fireproof warehouse or a fireproof chamber, or as a fireproof heat insulating material structure of a fireproof or heat insulating structure, and its application is not particularly limited. The temperature of the melting point of the chemical heat storage material 1 is, for example, 40% urea.
Since the temperature can be appropriately set by a known structure such as addition of at least wt%, the optimum temperature may be set according to the application of the refractory insulation structure. Further, the chemical heat storage material 1 is preferably arranged over the entire surface of the wall material 2, but when the wall material 2 is bonded, it is necessary to provide a bonding portion. The refractory heat insulating material structure of FIG. 5 has a pair of wall materials 2 provided with concave portions 3, 3, 3, .. Of the refractory insulation material, the chemical heat storage material 1'having a lower melting point than the chemical heat storage material in the middle part 1'for example, Na 2 HPO 4 · 12H 2 O near the iron plate 5 inside
(Melting point 36 ° C) etc. built-in. According to this, the chemical heat storage materials 1, 1 are spread over substantially the entire surface of the wall material 2.
.. can be arranged, heat conduction can be suppressed uniformly, and the chemical heat storage materials 1 and 1 ′ are arranged at different positions in the thickness direction between the middle part and the inner part, so that it is more efficient. The heat resistance effect can be achieved. An example of the arrangement of the chemical heat storage materials 1, 1'is, for example, a plurality of chemical heat storage materials having the same melting point or different melting points are arranged at different positions in the thickness direction of the refractory heat insulating material, This is preferable because it can suppress heat conduction in multiple layers. In addition, in the present invention, the mounting structure of the chemical heat storage material filled in the package and the wall material is not particularly limited, and at least gelled (or gelled and further heated to a predetermined temperature). It is sufficient that the wall material is in contact with the heat storage material so that it can absorb the moisture of the chemical heat storage material. The wall material may be one kind or many kinds, and may be used in combination with other known fire resistant structures.
