る。2. Description of the Related Art Although metal doors have excellent fire resistance,
Due to the cold appearance peculiar to metal and the heavy weight, doors made of wood have been generally used. And it is generally understood that wood burns easily, but in reality, it can withstand a fire for a short time and is used as a fire-resistant door that shuts off the flame and prevents burning. It is also possible.

け抜けが発生するおそれがあるという問題もあった。However, when a flame locally acts on a door made of wood, a local temperature rise occurs due to partial concentration of heat, and the burnout occurs at this location in a short time. May occur, and flame or smoke may enter through the holes created by the burnout, and the flame or smoke may not be blocked. Also, when flame acts on the joints of the members that make up the door, such as the joints between the vertical and horizontal frames that make up the frame of the door, and the joints between the frame and the door face plate, the joints will contract due to the contraction of each member. There is a risk that a gap will be created in the space, and flame or smoke will enter through this gap, making it impossible to block the flame or smoke. Further, although metal parts such as door knobs and hinges are attached to the door, if the metal parts are exposed to heat during a fire, the metal parts become extremely hot and there is a risk that the door will burn through at this part. There was also a problem.

度が好ましい。The molding material containing the carbonaceous powder and binder resin will be described in detail below. The carbonaceous powder can be generally used as long as it is a carbonaceous powder, and for example, natural graphite, artificial graphite, carbon black, coke powder, charcoal powder, rice husk charcoal can be used. These may be used alone or in combination of two or more. The particle size of the carbonaceous powder is not particularly limited, but is 1 to 1000
About μm is preferable. The carbonaceous powder can be used by blending expanded graphite powder in addition to those listed above. This expanded graphite is obtained by greatly expanding the interlayer of flake graphite in the direction perpendicular to the layer surface. That is, graphite has a crystal structure in which layers of hexagonal net-like planes of carbon are stacked, and various substances can be inserted between the layers. For example, when treated with a mixed solution of concentrated sulfuric acid and an oxidant, the sulfuric acid between the layers is reduced. Infiltrate into graphite intercalation compound, which rapidly
When heated at a temperature of about 00 to 1000 ° C., sulfuric acid and the like are decomposed and gasified, and the pressure causes the graphite layers to expand tens to hundreds of times in the direction perpendicular to the layer surface. This expanded graphite is called expanded graphite (or expanded graphite).
As the expanded graphite, a commercially available powder can be used as it is, but the particle size thereof is preferably about 30 to 800 μm.

This binder resin is adhered to the surface of the carbonaceous powder to prepare a self-hardening composite material, and this self-hardening composite material is used as the molding material.
That is, the initial condensate of carbonaceous powder and thermosetting resin, for example, phenol resin, melamine resin, or furan resin is put into a kneader, and after kneading these with a solvent such as alcohol, the kneaded product is taken out from the kneader. , This is put into an extrusion molding machine, further extruded while being kneaded to dry the extrusion molded product, and by crushing this, a granular material having a thermosetting resin adhered to the surface of the carbonaceous granular material. Can be obtained.

る。Further, in preparing the self-curing composite material, the thermosetting resin should be attached to the surface of the carbonaceous powder at the same time as the preparation of the initial condensate of the thermosetting resin. You can also This is the method provided by the present applicant as Japanese Patent Application No. 61-191083. For example, when preparing an initial condensate of a phenol resin, phenols and aldehydes are added to a reaction vessel in the presence of a catalyst and carbon. The phenolic resin is uniformly attached to the surface of the carbonaceous powder by reacting it while mixing with the powdery granules, and this is filtered and dried to obtain a self-curing composite material as spherical powders. Is what you can get. A self-curing composite material can be obtained with a melamine resin or a furan resin in the same manner as this method. In the case of melamine resin, a self-hardening composite material can be obtained as a spherical powder or granule as in the case of a phenol resin, but in the case of a furan resin, it cannot be generally prepared into a spherical powder or granule, It will be used after freeze-drying.

There is no such problem when preparing a self-hardening composite material by mixing, and a self-hardening composite material containing a large amount of carbonaceous powder particles can be easily dispersed as well as uniformly dispersing the carbonaceous powder particles. It can be prepared. Therefore, the method of preparing the self-curing composite material is not limited in any way, but the latter method is more preferable. In order to obtain sufficient thermal conductivity, the content of the carbonaceous powdery particles in the molding material is preferably 30% by weight or more. In addition to carbonaceous powders, powders such as alumina and magnesia can be blended if necessary, and fibrous or lightweight aggregates etc. should be added as reinforcements and extenders.

It is preferable to use silica sand as the sand, which is not particularly limited, but the particle size is 1 to 5
It is preferably about 00 μm. The sand may be directly mixed with the self-hardening composite material, but it is preferable that the sand is prepared and used in the form of resin coated sand. The resin coated sand is a sand surface coated with a self-curing thermosetting resin, and it is preferable to use the same resin as the resin of the self-curing composite material as the coating resin. This resin is a molding material. It constitutes a part of the binder resin. When the resin coated sand is prepared by coating sand with a resin, a dry hot coating method, a cold coating method, a semi-hot coating method, a powder solvent method or the like can be used. The dry hot coating method is that solid resin is added to heated sand and mixed, and the solid resin is melted by heating with sand to wet and coat the surface of the sand with the molten resin, after which while maintaining this mixing. Cool down
This is a method of obtaining a granular, resin-coated sand. The cold coating method is a method of obtaining a resin coated sand by dissolving a resin in a solvent such as methanol to form a liquid, adding this to sand, mixing the mixture, and volatilizing the solvent. The semi-hot coating method is a method in which a resin dissolved in the above solvent is added to and mixed with sand heated to about 50 to 90 ° C. to obtain a resin coated sand. The powder solvent method is a method in which a solid resin is crushed, the crushed resin is added to sand, a solvent such as methanol is further added, and this is mixed to obtain a resin coated sand. Although any of the above methods can provide a resin-coated sand that is granular and free-flowing, the dry hot coating method is preferable in terms of workability and the like. Further, as described above, a curing agent, if necessary, at the time of mixing to prepare the resin coated sand, and other various coupling agents such as a silane coupling agent for making the sand and the resin compatible with each other,
Further, a lubricant such as calcium stearate may be added. The plate-shaped heat conduction plate 2 can be prepared by heating and pressing the molding material obtained as described above to cure the binder resin.
