(First embodiment)
A structure of a fireproof panel according to one embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

<1. Fireproof panel structure>
FIG. 1 is a perspective view of a fire rated panel 100 in one embodiment of the invention. FIG. 2 is an end view of the fireproof panel 100 cut along line A1-A2. The fire rated panel 100 defines a first direction D1, a second direction D2 perpendicular to the first direction D1, and a third direction D3 perpendicular to the first direction D1 and the second direction D2.

The fireproof panel 100 has a length L3 (thickness) along the third direction D3, and a length L1 along the first direction D1 and a length L3 along the second direction D2 that are larger than the length L3. is a rectangular plate with The length L3 of the fire resistant panel 100 is between 50 mm and 200 mm, between 70 mm and 120 mm, or between 70 mm and 120 mm. Also, the length L1 of the fireproof panel 100 is 50 cm to 200 cm, 50 cm to 150 cm, or 70 cm to 150 cm. The length L2 of the fire-resistant panel 100 is between 1 m and 10 m, between 1.5 m and 5 m, or between 2 m and 5 m.

The fireproof panel 100 is constructed using a honeycomb material 101 having a first surface 101a and a second surface 101b opposite to the first surface 101a, a pair of incombustible materials 102 and 103, and a pair of decorative materials 104 and 105. be. The fireproof panel 100 is provided with a noncombustible material 102 and a decorative material 104 on a first surface 101a of a honeycomb material 101, and a noncombustible material 103 and a decorative material 105 on a second surface 101b of the honeycomb material 101. That is, the fireproof panel 100 is provided with the noncombustible material 102 and the noncombustible material 103 so as to sandwich the honeycomb material 101 . The fireproof panel 100 is a so-called sandwich panel in which decorative materials 104 and 105 are provided so as to sandwich a honeycomb material 101 and incombustible materials 102 and 103 . The length L1 of the fireproof panel 100 corresponds to the width of the facing materials 104 and 105, and the length L2 of the fireproof panel 100 corresponds to the height of the facing materials 104 and 105. Also, the length L3 of the fireproof panel 100 corresponds to the sum of the thicknesses of the honeycomb material 101, the incombustible materials 102 and 103, and the decorative materials 104 and 105.

The honeycomb material 101 is used as a heat insulating material. The honeycomb material 101 does not have to be fireproof, and honeycomb materials 101 made of any material can be applied. Here, fire resistance refers to the ability to suppress the spread of fire caused by normal fires that occur around buildings. The honeycomb material 101 is composed of various materials such as non-combustible paper honeycomb material, cardboard, aluminum honeycomb material, or ceramic honeycomb material. For example, when a ceramic honeycomb material, an aluminum honeycomb material, or noncombustible paper is used as the honeycomb material 101, the fire resistance can be improved. The thickness of the honeycomb material is, for example, 15 mm to 50 mm, 20 mm to 50 mm, or 20 mm to 40 mm, and in this embodiment is 30 mm.

The shape of the cells in the cross section orthogonal to the direction in which the cells of the honeycomb material 101 extend (thickness direction of the honeycomb material 101) is not particularly limited, and may be, for example, a square, a hexagon, an octagon, or a combination of these shapes. good. The cell size d in the cross section of the honeycomb material 101 is 5 mm to 50 mm, 10 mm to 40 mm, or 25 mm to 35 mm, and is 30 mm in this embodiment. Moreover, the porosity of the honeycomb material 101 is, for example, 91% to 95%.

The honeycomb material 101 has a honeycomb structure, and 90% or more of the volume is air, so the weight of the fireproof panel 100 can be reduced. Moreover, since the honeycomb structure can prevent air convection, the heat insulation of the fireproof panel 100 can be improved. In addition, the honeycomb structure has high bending strength and can increase strength against planar pressure.

The non-combustible materials 102, 103 are used as refractory coatings. The noncombustible materials 102 and 103 are composed of various materials such as wood boards such as insulation boards, cellulose fiber boards, wood wool cement boards, and inorganic boards such as gypsum boards and calcium silicate boards. . The thickness of the non-combustible material is between 7 mm and 50 mm, between 10 mm and 40 mm, or between 12.5 mm and 30 mm, and in this embodiment is 20 mm.

The decorative materials 104 and 105 are made of various materials such as, for example, ceramic-based decorative materials (ceramic-based), color steel plates, galvanium steel plates, aluminum plates, wallpaper, and wood-based plates. The thickness of the decorative material is thinner than the thickness of the incombustible materials 102, 103, and is 4 mm to 15 mm, 5 mm to 12 mm, 8 mm to 12 mm, and 9.5 mm in this embodiment. By using the decorative materials 104 and 105, it is possible to suppress deterioration of the fireproof panel 100 due to deformation, discoloration, deterioration, or the like. In addition, the appearance of the fireproof panel 100 is improved, and the design is improved.

The honeycomb material 101 and the incombustible materials 102 and 103 are bonded with an admixture. Further, the nonflammable materials 102, 103 and the decorative materials 104, 105 are adhered with an admixture. As the admixture, an ammonium polyphosphate-based (coated or impregnated on a wooden board) non-flammable agent, a urethane-based, an epoxy-based, a sodium silicate-based, or a water glass-based adhesive can be used.

In the fireproof panel 100 , a pair of incombustible materials 102 and 103 and a pair of decorative materials 104 and 105 are provided symmetrically with respect to the honeycomb material 101 . It is preferable that the pair of incombustible materials 102 and 103 are made of the same material, have the same shape, and have the same thickness. Moreover, it is preferable that the pair of decorative members 104 and 105 are made of the same material, have the same shape, and have the same thickness.

In conventional fire-resistant panels, sepiolite, which has a heat resistance temperature higher than 400° C. to 500° C., must be used as the non-combustible honeycomb structural material, which limits the materials that can be used as the non-combustible honeycomb structural material.

According to the fireproof panel 100 in one embodiment of the present invention, by using an aluminum honeycomb material or a ceramic honeycomb material as the honeycomb material 101, the noncombustibility of the fireproof panel 100 can be enhanced. In addition, since the honeycomb material 101 has higher compressive strength and bending strength than when cardboard, noncombustible paper, or sepiolite is used, the mechanical strength of the fireproof panel 100 can be further improved. In addition, by using noncombustible decorative materials as the decorative materials 104 and 105 as well as the honeycomb material 101 and the noncombustible materials 102 and 103, all the materials constituting the fireproof panel 100 become noncombustible. and fire resistance can be further improved.

According to the fire-resistant panel 100 in one embodiment of the present invention, inorganic boards such as gypsum board or calcium silicate board are used as the non-combustible materials 102 and 103, for example. This makes it possible to use any decorative material other than a wood-based material in place of the steel decorative material used in the sandwich panel. As a result, it is possible to change the image concept of sandwich panels and apply them to buildings that require a variety of designs. As the honeycomb material 101, materials such as ceramic material, aluminum material, non-combustible paper, or cardboard can be used. In particular, when gypsum boards are used as the incombustible materials 102 and 103, the moisture (water of crystallization) contained in the gypsum boards is released in the event of a fire, thereby suppressing the temperature rise of the fireproof panel 100. . Also, the nonflammable materials 102 and 103 may be impregnated with a flame retardant such as a phosphoric acid chemical. Thereby, fireproof performance can be improved more.

According to the fire-resistant panel 100 in one embodiment of the present invention, when wood-based boards are used as the non-combustible materials 102 and 103, it is preferable to use a decorative steel material such as a color steel plate or a galvanium steel plate. Thereby, the fire resistance of the fire-resistant panel 100 can be improved.

According to the fireproof panel 100 in one embodiment of the present invention, the honeycomb material 101 is used as the heat insulating material. The honeycomb material 101 can be made lighter than rock wool, which has been conventionally used as a heat insulating material. Therefore, the weight of the entire fireproof panel 100 can be reduced.

As described above, various materials can be used as the honeycomb material 101 regardless of the heat resistance temperature, and the fireproof panel 100 with high fireproof performance can be provided.

<2. Fireproof panel manufacturing method>
Next, a method for manufacturing the fireproof panel 100 will be described.

First, the admixture is applied to the first surface 101a and the second surface 101b of the honeycomb material 101 . A noncombustible material 102 is attached to the first surface 101a of the honeycomb material 101, and a noncombustible material 103 is attached to the second surface 101b. Next, an admixture is applied to the nonflammable materials 102 and 103 . A decorative material 104 is attached to the incombustible material 102 , and a decorative material 105 is attached to the noncombustible material 103 .

Through the above steps, the fireproof panel 100 according to one embodiment of the present invention can be manufactured.

Mineral fiber rock wool, which has hitherto been used as a heat insulating material, causes an increase in CO ₂ emissions due to blast furnace slag during its production, and causes pollution due to dust. In addition, since rock wool contains sulfur, there is a problem that the steel plate is corroded.

In the fireproof panel 100 according to one embodiment of the present invention, a honeycomb material 101 is used as a heat insulating material instead of rock wool. As a result, it is possible to reduce the amount of CO ₂ emitted during the manufacturing process while maintaining the same thermal conductivity as rock wool. In addition, the wood-based boards used as the non-combustible materials 102 and 103 can be manufactured, for example, by reusing thinned wood, which promotes the effective use of earth's resources.
