Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof panel which can be applied to, for example, a finishing panel for an inner wall surface or a ceiling surface of a building.

[0002]

2. Description of the Related Art Conventionally, as a fireproofing panel for finishing the inner wall surface and ceiling surface of a building, a substrate made of asbestos slate plate, asbestos calcium silicate plate, etc.
The one to which a decorative material such as a wood veneer is attached is used.

Such a panel is generally constructed by a glue nail construction method in which both an adhesive and a nail are attached, or an adhesion construction method in which the nail is pulled out after construction.

[0004] In the glue nail construction method, a panel is adhered to a wall base such as a furring strip with an adhesive, and a nail is driven from the panel surface to the furring strip to fix the panel. Are to be lined up one after another for construction.

On the other hand, in the bonding method, the panel is adhered to the furring strip with an adhesive, and nails for temporary fastening are hammered into the furring strip from the surface of the panel to fix it. The nails for temporary fastening are pulled out after the entire area of the construction surface is successively constructed and the adhesive is hardened.

[0006]

However, in the past, when the finishing panel was constructed by the glue nailing method, the head of the nail driven in during construction is exposed on the surface of the panel after the construction. There was a problem that his head was conspicuous and his aesthetics was spoiled. Further, even in the bonding method, there are problems that a large number of nail drawing holes are conspicuous and the aesthetic appearance is impaired, and the number of working steps is increased due to the nail drawing, which makes the construction work troublesome.

On the other hand, the conventional finishing panel is equipped with an inorganic plate which has a higher specific gravity and is harder and more brittle than wood, or an inorganic plate which is lower in specific gravity and is more brittle than wood. It is difficult to form a joint processing part such as a bevel, a notched part, and a real part, and even if it can be processed into such a shape, if a nail is driven into that part, it will be chipped or cracked. Or, the peripheral end face is usually cut vertically because it does not sufficiently fulfill the function of the joint processing portion due to deformation or collapse. Therefore, irrespective of the glue nailing method and the adhesive method, even if the panel to be applied next is placed side by side with the panel that has already been fixed during panel installation, it is difficult to position and temporarily fix the panel, and nailing work etc. I can't do it smoothly by myself,
There is also a problem that the construction work cannot be carried out smoothly, because it is necessary to use a support rod or two or more people do it.

The present invention solves the above-mentioned problems of the prior art, and can form a processed portion for joining such as a tongue portion for joining panels at least on both sides, for example, on an inner wall surface or a ceiling surface. It is an object of the present invention to provide a fireproof panel for a building which, when applied to a finishing panel or the like, can easily perform a construction work and can obtain a good appearance after the construction.

[0009]

In order to achieve the above object, the present invention comprises a plate-like core material provided with a substrate to which end materials are adhered along at least both side edges, the core material comprising:
Along with the inorganic plate, the end material is a main material composed of an inorganic powder or granular material, and a reinforcing material composed of a fiber,
The gist of the present invention is that it is formed of a foam plate mixed with a binder made of synthetic resin.

The detailed construction of the present invention will be described below with reference to an example of a fireproof panel for buildings shown in the drawings.

As shown in FIG. 1, the fireproof panel for a building has a substrate (10) in which end materials (12) are attached to both side edges of a plate-shaped core material (11), The board (10)
The surface sheet material (20) is attached to the surface of the
A back sheet material (30) is attached to the back surface.

In the present invention, as the core material (11),
Any plate can be used as long as it is made of an inorganic material having incombustibility or quasi-incombustibility, for example, asbestos slate plate, pulp cement plate, asbestos cement barlite plate, calcium silicate plate, fiber mixture. Calcium silicate board, fiber-containing slag gypsum board, fiber-containing slag cement board, fiber-containing cement board, gypsum board, one kind of single-layer board selected from among honeycomb cores or one or more kinds of laminated board are preferably used can do.

Further, as the core material (11), a rock wool plate, a glass wool plate,
Glass wool mats, polyurethane foams, polyisocyanurate foams, phenolic foams, polyphenylene foams, polyamide foams, honeycomb cores, and other materials that have low specific gravity and weak nail holding power, and end materials that will be described in detail later (12).
It is also possible to use a laminate of plates used as.

Further, when stacking these core material constituent plates, it is possible to stack core material constituent plates having different areas (sizes) from each other, and a method such as staggering (staggered stacking) is adopted. Is also possible.

As the laminating adhesive, phenol resin adhesives, urethane resin adhesives, epoxy resin adhesives, crosslinked vinyl acetate resin adhesives, synthetic rubber adhesives and the like can be preferably used.

The thickness of the core material (11) is preferably set to be the same as that of the end material (12) described in detail below.

The end material (12) is mainly composed of a non-combustible and quasi-noncombustible inorganic powder, and the main material is a reinforcing material made of fibers and a binder (binding material) made of synthetic resin.
It is necessary to form a foam plate in which and are mixed.

The inorganic powder or granular material is one or more selected from aluminum hydroxide, calcium carbonate, calcium silicate, magnesium hydroxide, aluminum silicate, magnesium silicate, perlite, gypsum, lime and the like. Etc. can be used suitably.

Further, as the reinforcing material, inorganic fibers such as glass fiber, rock wool and ceramic fiber, iron fiber, aluminum fiber, metal fiber such as whiskers, natural fiber such as pulp, cotton and wood fiber, nylon, acrylic and polypropylene. One or more selected from synthetic fibers such as polyvinyl alcohol and the like can be preferably used. Among these, it is particularly preferable to use glass fiber having high rigidity.

As the binder, at least one selected from phenol resin, furan resin, vinyl chloride resin, urea / melanin resin, styrene / butadiene rubber resin and the like can be preferably used. .
Among these, it is preferable to use a phenol resin that has a three-dimensional network structure after curing and has a high binding force and excellent flame retardancy.

In the present invention, the end material (12) is composed of a foam plate containing the above-mentioned main material (inorganic powder and granules), reinforcing material (fiber) and binder (synthetic resin).
In producing this foamed plate, it is preferable to set the mixing ratio of the main material to 75 to 97% by weight, the mixing ratio of the reinforcing material to 1 to 15% by weight, and the mixing ratio of the binder. It is preferably set to 2 to 10% by weight.

That is, the main material is a material for exhibiting fireproof performance, and the higher the content, the more the fireproof performance improves. However, when the blending ratio of the main material exceeds 97% by weight, relatively, When the blending ratio of the reinforcing material and the binder is decreased and the strength is lowered, and when the blending ratio of the main material is less than 75% by weight, the blending ratio of the reinforcing material and the binder is relatively increased, and the material is used as a panel material. It is not preferable because good moldability cannot be obtained and the fireproof performance is deteriorated.

Further, if the compounding ratio of the reinforcing material is less than 1% by weight, the entanglement between the fibers is reduced and the strength is lowered. On the other hand, if the blending ratio exceeds 15% by weight, the dispersibility of the reinforcing material deteriorates when the reinforcing material is mixed during the manufacturing of the scrap material, and a good scrap material cannot be obtained, which is not preferable.
The end material (12) is treated by a non-woven fabric impregnation method (a method in which a non-woven fiber mat is impregnated with another material, and the fibers are fibrillated and diffused by the binder curing reaction and the binder flow in the foaming process). Even in the case of production, the same as above, diffusion and dispersion of the reinforcing material (fiber) deteriorates, which is not preferable.

Further, the compounding ratio of the binder is 10% by weight.
If the content exceeds the above range, the strength is improved, but the fireproof performance is remarkably deteriorated, and if it is less than 2% by weight, the bondability is deteriorated and the strength is deteriorated, which is not preferable.

Preferred examples of the foamed plate having such a constitution include glass fiber mixed aluminum hydroxide / phenolic resin foamed plate, glass fiber mixed aluminum hydroxide / calcium carbonate / phenolic resin foamed plate, and asbestos mixed aluminum hydroxide.・ Vinyl chloride resin foam board (aluminum hydroxide mixed vinyl chloride resin foam board), inorganic substance (calcium carbonate, magnesium hydroxide and aluminum hydroxide) mixed vinyl chloride resin foam board, etc. can be mentioned. It is possible to use one selected single-layer board or one or more laminated boards.

It should be noted that the end material (12) made of such a specific material is capable of forming a joint-processed portion having a main zigzag shape, a notched shape, a slightly actual shape and their deformed shapes without any trouble. Moreover, the nail can be driven, and the nail that has been driven can be held well.

The thickness of the end material (12) is set to 5 mm or more, preferably 7 mm or more. If the thickness is less than 5 mm, the strength of the joint-processed portion such as a tongue portion, which will be described later, decreases, and the nail holding force also decreases, and good workability cannot be obtained during construction, which is not preferable.

Further, the width dimension of the end material (12) may be appropriately set according to the shape of the processing portion for bonding described later.

The method of joining the core material (11) and the end material (12) is not particularly limited. For example, a butt joining method,
In addition to the scarf joining method, the slightly actual joining method, the phaseless joining method, and the like, known joining methods such as a dowel joining method such as a plug-like dowel, a rod-like dowel, and a flat plate-like dowel can be adopted. Among these joining methods, when the very actual joining method is adopted, an inorganic plate, a metal plate, or the like is used as the very actual material, which is stronger than the core material (11) and the end material (12) ( If the bending strength is particularly strong, the strength of the panel end portion is improved and the panel end portion is reinforced.

Adhesives used for joining the core material (11) and the end material (12) include epoxy resin, urethane resin, phenol resin, crosslinked vinyl acetate resin, synthetic rubber and the like. It can be used preferably.

If a step is formed between the core material (11) and the end material (12) after they are bonded, it is preferable to remove the step by grinding.

The end material (12) may be provided on at least both side edges, and the four peripheral edges of the core material (11),
It may be provided on three side edges of the four side edges. In other words, the end material (12) may be provided at a portion where a joining processed portion such as a tongue portion, which will be described later, is to be formed.

Further, the substrate (10) formed by joining the core material (11) and the end material (12) together with the top sheet material (20), the back sheet material (30), the decorative material described later, and the like. To improve the adhesiveness, urethane resin type, epoxy resin type, vinyl acetate
Treatment with a silicate-based or ceramic-based (water glass, etc.) sealer is desired.

In the present invention, the surface sheet material (20) is on the front surface side of the substrate (10) and the back surface sheet material (30) is on the back surface side.
Is preferably attached.

Preferable specific examples of the top sheet material (20) and the back sheet material (30) are paper, non-woven fabric, woven fabric,
Wood veneer etc. can be mentioned. Furthermore, as a material having moisture resistance, one or both sides of a synthetic resin sheet or film such as polyethylene or polypropylene,
Illustrative examples include two-layer or three-layer or more moisture-proof sheets in which paper, non-woven fabric, woven fabric, wood veneer, inorganic paper, metal sheet (aluminum, lead) or the like is adhered or heat-sealed. In the case of three or more layers, both sides may be composed of different kinds, and the same kind or different kinds may be used.

Further, as the sheet material excellent in fireproofness, in addition to the above-mentioned sheet material which has been subjected to the flame retardant treatment,
Examples thereof include inorganic papers containing 50% by weight or more of inorganic powder particles such as aluminum hydroxide, magnesium hydroxide, gypsum and calcium carbonate.

The sticking of the surface sheet material (20) has the following advantages. For example, the decorative material described below is 0.1
When the surface sheet material (20) is absent when the thickness is about 5 mm, the surface of the substrate (10) is seen through the decorative material, and the core material (11) and the end material (12) of the substrate (10) are separated. An aesthetic defect such as a joint or a difference in color between the two, or an aesthetic defect such as a blowout part of the adhesive caused by a difference in the permeability of the adhesive for adhering the decorative material to the core material (11) and the end material (12) Although it may be perceived and impair the finishing feeling, if the surface sheet material (20) is adhered, all of these defects are hidden, and a good aesthetic appearance can be secured without impairing the finishing feeling.

Further, when a moistureproof material is used as the surface sheet material (20), the sheet material (20) prevents the alkali component in the substrate (10) from migrating to the decorative material side, and the wood material A decorative material such as a veneer is prevented from discoloring into an unpleasant blue or black color due to alkali contamination, and a good aesthetic appearance can be maintained. Further, when a material having excellent fireproof property is used, the fireproof performance of the fireproof panel itself can be further improved.

The surface sheet material (20) may be adhered to the back surface side of the decorative material described later in manufacturing the panel.

On the other hand, when the back sheet material (30) is attached, the aesthetic defects on the back surface side of the substrate (10) can be concealed to suppress discomfort and the inorganic material forming the substrate (10) can be suppressed. You can soften the unique coldness. Further, since it is possible to prevent direct contact with glass fibers or the like mixed in the substrate, it is possible to suppress irritation felt on the skin at the time of contact.

When a back sheet material (30) having a moisture proof property is used, it is possible to prevent moisture absorption from the back surface side of the panel and avoid adverse effects due to moisture absorption.
Further, when a material having excellent fireproof property is used, the fireproof performance of the fireproof panel itself can be further improved.

When the fireproof panel having the above-mentioned structure is used as a panel for finishing the inner wall surface or ceiling surface of a building, for example, as shown in FIG. 2, the substrate (10) or the surface sheet material (20) is coated with makeup. While the material (40) is provided,
The joining processed portion such as the male part (13) is formed on one side and the joining processed portion such as the female part (14) is formed on the other side.

As the decorative material (40), suitable is a sheet-shaped material such as a wood veneer, a pattern printing paper, a vinyl chloride sheet, a synthetic resin impregnated decorative paper, or a substrate (10) or a surface sheet material (20). Examples include those formed by applying different paints.

When the decorative material (40) is composed of a sheet-like material, the adhesive for adhering it is urea resin type, melamine / urea co-condensation type, urea / vinyl acetate resin type, α-olefin. Known adhesives such as resin type, vinyl urethane resin type and epoxy resin type can be preferably used. Further, in such an adhesive, by adding a known flame retardant / fireproof agent such as a phosphoric acid flame retardant, a boric acid flame retardant, a guanidine flame retardant, or aluminum hydroxide, the fireproof panel itself The fireproof performance can be further improved.

In the present invention, the shape of the processed portion for joining is
The shape is not limited to the shape of the book, and any shape may be used. However, as described below, the shape of the book nail is to be hidden or concealed in order to hide the construction nails. It is advisable to adopt a real shape and a modified version thereof.

Further, it is sufficient that the processing portion for bonding is formed on at least two sides of the panel, and the four sides and the four sides.
It may be provided on three sides. In addition, in the case where the joining processed portion is formed on other than the two sides, it is necessary to attach the end material (12) also to the joining processed portion forming portion.

Next, the case where the finishing panel having the above-mentioned structure is applied to the inner surface of the side wall of the building by the combined use method of glue nails will be described.

As shown in FIG. 3, first, the back side of the panel is adhered to the furring strip (1a) of the building frame with an adhesive and the nail (2) is attached to the base end portion of the male section (13). It is driven in and fixed to the furring strip (1a).
