Abstract

PURPOSE: To inexpensively provide a flameproof panel for which a base material excellent for the property of pinning up a picture or the like is used, and which is also excellent for a flame-retardant property and simultaneously holds pinup property. CONSTITUTION: In time of a fire, heat transmitted from a sheet-like decorative material 5 is transmitted to calcium silicate paper 4 when the sheet-like decorative material 5 is touched by flames. At this time, the thermal conductivity of the calcium silicate paper 4 is low, and hence the heat is not much diffused, and a locally high-temperature state is produced. When this temperature furthermore rises as time elapses and is beyond a specified value, a flame retardant in an adhesive decomposes, emits inert gas, and it checks the spread of the fire. Furthermore, the calcium silicate paper 4 has weak resistance to pinning-up, and does not spoil the pinup property.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flameproof panel whose surface is covered with a sheet-like decorative material, and more particularly to a flameproof panel excellent in flameproof performance and pinup property.

[0002]

2. Description of the Related Art Conventionally, as a panel having a flameproof property whose surface is covered with a sheet-shaped decorative material, a sheet-shaped decorative material is subjected to a flameproofing treatment, and a non-combustible material such as steel or gypsum board However, when the core material is used again, rock wool or aluminum honeycomb, which is also an incombustible material, was used.

As described above, in the case where the steel material or the gypsum board is used as the base material, it is necessary to use a predetermined reinforcing material or increase the thickness for the purpose of obtaining strength and rigidity as a flat panel. The cost was high and the weight was heavy, which made transportation and construction difficult. Further, when steel or gypsum board is used, the pin-up property is lost, and there is a problem that papers cannot be displayed on the panel by pins such as thumbtack.

Also, as effective materials for improving the pin-up property, insulation board, rock wool board, cork, and balsa wood are effective, but when these materials are used as the base material, the material becomes flammable. Therefore, sufficient flameproof performance cannot be obtained. Under such circumstances, a panel that shares both flameproof performance and pin-up performance has been desired.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, the present invention uses a base material having excellent pinup property, which is flammable such as fiberboard, plywood, and wood, and The purpose of the invention is to provide a flameproof panel which is excellent in flameproofing performance at a low cost while being retained.

[0006]

In order to solve the above-mentioned problems, the flameproof panel of the present invention is a flammable fibrous board, plywood, wood or the like, which has silicic acid on the surface side of a base material which is excellent in pinup property. It is characterized in that calcium paper is adhered with an adhesive containing a flame retardant, and that a sheet-like decorative material that is flameproofed is adhered to the surface side of calcium silicate paper with an adhesive containing a flame retardant. .

The flameproof panel of the present invention comprises a core material such as a honeycomb material or a synthetic resin foam, and a flammable material such as fiber board, plywood, and wood joined to both surfaces of the core material, which is excellent in pinup property.
Calcium silicate paper is bonded to the surface side of each base material with an adhesive containing a flame retardant, and a flame-retardant sheet-shaped decorative material is mixed with a flame retardant on the surface side of each calcium silicate paper. It is characterized in that it is adhered by the adhesive.

[0008]

[Function] When a flame touches the sheet-shaped decoration material during a fire,
The heat transferred from the sheet-shaped decorative material is transferred to the calcium silicate paper, but since the calcium silicate paper has a low thermal conductivity, the heat is not diffused so much and a local high temperature state occurs. When this temperature further rises with time and exceeds a certain value, the flame retardant in the adhesive decomposes and an inert gas is released to prevent the spread of fire. Furthermore, since calcium silicate paper retains its shape even at high temperatures as a property, it obstructs the supply of air to make it difficult for the base material to burn, and because the heat diffusion area is small, it can be used as a sheet-like decoration material. Demonstrates excellent flameproof performance, such as preventing the carbonized area to be minimal and preventing fire spread.

Further, calcium silicate paper has little resistance to passing through the pin and does not impair the pin-up property.

Even when a paper honeycomb, a synthetic resin foam or the like is used as the core material, the heat cannot be easily transferred to the core material due to the calcium silicate paper and the base material, and the core material may be gasified or burned out. Absent. Therefore, the flameproof panel can be made lightweight and have multiple functions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a flameproof panel 1 to which the present invention is applied. Both sides of an upper frame 2, that is, both front and back surfaces of the panel are shown. The base material 3, the calcium silicate paper 4, and the sheet-shaped decoration material 5 are arranged in layers. In addition, 8 is an upper cover fixed in series on the upper frame 2 made of steel. Further, 6 is a core material provided in a space portion in the flameproof panel 1.

A local portion A of the flameproof panel 1 is shown in an enlarged view in FIG. 2, and the details of the layered portion will be described with reference to FIG.

If necessary, a core material 6 is provided inside the layer, and the core material is, for example, a honeycomb, a synthetic resin foam (for example, phenol, urethane, polyethylene-based resin foam) or an inorganic material. System board (eg gypsum board,
Cement board) can be used. Here, the core material 6 is
It does not necessarily have to be internally provided, and is appropriately selected according to various required functions such as strength, heat insulation, and soundproofing.

A base material 3 is disposed on the outer side of the core material 6, and the base material is a fiberboard, plywood, wood or the like having a pin-up property, such as insulation board, rock wool board, cork and balsa material. Is used.

Next, the calcium silicate paper 4 is attached to one surface of the outside of the base material 3 with an adhesive 7. This calcium silicate paper is made of fibers synthesized by hydrothermal reaction using lime nitrate and silica stone as the main raw materials, and has the property of extremely low heat conductivity and the property of retaining its shape even when exposed to high temperatures. I have a combination.

The calcium silicate paper 4 is a kind of paper, and the pins are easily penetrated without being significantly affected by its thickness, and if a thick paper is used, it also has a pin holding effect. become.

Further, on the surface of the calcium silicate paper 4, a sheet-like decorative material 5 flameproofed by an adhesive 7,
That is, the cloth is attached. As the adhesive 7 used here, a halogen-based, organic phosphorus-based, or organic sulfur-based adhesive is used as the flame-retardant-mixed adhesive component, and the adhesive 7 adheres when exposed to high heat. It has a function of decomposing the flame retardant in the agent and releasing an inert gas.

The flameproof panel thus constructed is
When the flame touches the sheet-shaped decoration material 5, the heat transferred from the sheet-shaped decoration material 5 is transferred to the calcium silicate paper 4,
Since the calcium silicate paper 4 has a low thermal conductivity, the heat is not diffused so much and a local high temperature occurs. When this temperature further rises with time and exceeds a certain value, the flame retardant in the adhesive 7 is decomposed and an inert gas is released to prevent the spread of fire. Further, since the heat diffusion area is small, the carbonized area of the sheet-shaped decorative material 5 is hardly suppressed and spread of fire is prevented.

Further, the temperature of the calcium silicate paper 4 continues to rise with time in the event of a fire, but the calcium silicate paper 4 is stuck on the entire surface of the substrate 3 and its shape does not change even when exposed to high temperatures. Since it has the property, it functions to hinder the supply of air and make the base material 3 more difficult to burn. Particularly, as in this embodiment, the flameproof panel 1 is attached to the upper cover 8,
If the upper frame 2 made of steel, the vertical frame (not shown), and the calcium silicate paper 4 attached to the front and back are almost completely covered, the air supply can be cut off more effectively.

Further, since calcium silicate paper has little resistance to pass through the pin and does not impair the pin-up property, if a fiber board, plywood, wood, etc. are used for the base material 3, both will work together. It is possible to provide a flameproof panel that is excellent in pin-up properties, lightweight, sufficient in strength and rigidity, and inexpensive.

Furthermore, since the calcium silicate paper 4 is not in direct contact with the core material 6, in other words, there is a base material 3 such as fiberboard, plywood or wood between the core material 6 and the calcium silicate paper 4. Because of the interposition, it becomes possible to use a paper honeycomb, a synthetic resin foam or the like, which is weak against heat, as a core material, and the range of use choices for the core material 6 that satisfies various required functions (soundproofing, reinforcement, heat insulation, etc.) is expanded. .

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are changes and additions within the scope not departing from the gist of the present invention, the present invention is not limited. Included in the invention.

[0023]

The present invention has the following effects.

(A) When a flame touches the sheet-shaped decorative material during a fire, the heat transferred from the sheet-shaped decorative material is transferred to the calcium silicate paper, but the calcium silicate paper has a low thermal conductivity. Therefore, heat is not diffused so much and a local high temperature state occurs. When this temperature further rises with time and exceeds a certain value, the flame retardant in the adhesive decomposes and an inert gas is released to prevent the spread of fire. Furthermore, since calcium silicate paper retains its shape even at high temperatures as a property, it obstructs the supply of air to make it difficult for the base material to burn, and because the heat diffusion area is small, it can be used as a sheet-like decoration material. Demonstrates excellent flameproof performance, such as preventing the carbonized area to be minimal and preventing fire spread.

(B) In addition, the calcium silicate paper has little resistance to passing through the pin and does not impair the pin-up property.

(C) According to claim 2, even when a paper honeycomb, a synthetic resin foam or the like is used as the core material,
Due to the calcium silicate paper and the base material, heat is not easily transferred to the core material, and the core material is not gasified or burned out. Therefore, the flameproof panel can be made lightweight and have multiple functions.
