  However, there is an image that a decorative board using a brittle material such as a glass plate is easily broken because it is a brittle material. Moreover, when such a decorative board is cracked due to a large impact, there is a risk that the fragments will scatter. For this reason, glass decorative boards are used in buildings and stores, but are difficult to use in ordinary houses.

  This invention is made | formed in view of the said subject, Comprising: It aims at providing the decorative board which is hard to break even if a big impact is added, and does not fly even if it cracks.

  The decorative board of the present invention has a brittle plate having design properties and a resin layer laminated on the plate, and the resin layer has a thickness of 1.5 mm or more, and the resin The Shore A hardness of the layer is 10 or more and 60 or less.

  ADVANTAGE OF THE INVENTION According to this invention, even if a big impact is applied, it is hard to break and even if it breaks, the decorative board which does not fly can be provided.

It is typical sectional drawing of embodiment of the decorative board which concerns on this invention. It is typical sectional drawing of the decorative board with a reinforcing material of one Example of this invention.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments, and the following embodiments are not deviated from the scope of the present invention. Various modifications and substitutions can be made.

The decorative board according to the embodiment of the present invention includes a brittle plate having design properties and a resin layer laminated on the plate. The design property of the plate-like body may be expressed by the plate-like body itself having a pattern, color, etc., and the design property is imparted by the design layer interposed between the plate-like body and the resin layer. May be. The design layer interposed between the plate-like body and the resin layer includes a design layer directly formed on the surface of the plate-like body and a design layer directly formed on the surface of the resin layer.
Moreover, it is preferable that the resin layer of this embodiment is laminated | stacked on 80% or more of the surface of a plate-shaped object. More preferably, the resin layer is laminated on 90% or more of the surface of the plate-like body. By laminating a resin layer on the majority of the plate-like body, it becomes a decorative board that is difficult to break even when a large impact is applied, and that does not scatter even if cracked.
If the plate-like body is a brittle material, the effects of the present invention can be enjoyed. For example, a glass plate, a resin plate, and a ceramic plate are mentioned. Below, the example of the glass decorative board using a glass plate is demonstrated.
FIG. 1 is a schematic cross-sectional view showing this embodiment. The decorative board 1 in the present embodiment includes a glass plate 2, a resin layer 3 laminated on the glass plate 2, and a design layer 4 interposed between the glass plate 2 and the resin layer 3.

  The decorative board 1 of the present embodiment can be applied to various uses such as building materials such as walls and ceilings and storage furniture. By laminating the glass plate 2 with the resin layer 3, the glass plate 2 is reinforced to make it difficult to break, and even if it breaks, the glass piece 2 does not scatter due to the glass plate 2 and the resin layer 3 being bonded. High safety not found in conventional glass decorative panels. On the other hand, since the design layer 4 is brought into close contact with the glass plate 2 in the same manner as the conventional glass decorative plate, a high-quality aesthetic appearance can be produced.

As for the glass plate 2, although the kind of glass is not specifically limited, For example, soda-lime glass, an alkali free glass, an aluminosilicate glass, etc. are mentioned. When the chemical strengthening treatment is performed, an aluminosilicate glass containing 3% or more of Al ₂ O ₃ by mass% based on the oxide is preferable. The plate thickness of the glass plate 2 is preferably 0.5 mm or more. When the plate thickness of the glass plate 2 is 0.5 mm or more, sufficient strength can be obtained by laminating with the resin layer. It is more preferably 1.0 mm or more, and further preferably 1.5 mm or more. Moreover, since it is equivalent to the plate | board thickness of the conventional glass decorative board as the plate | board thickness is 8.0 mm or less, since the construction to a wall surface does not require a special operation | work similarly to the past, it is preferable. Moreover, it is more preferable that it is 6.0 mm or less.

By the way, the specific gravity of a glass plate is large, and the glass plate has a large area in a glass decorative plate applied to a wall surface, so that the weight becomes very heavy. Therefore, the construction of the glass decorative panel on the wall surface has not been easy because several workers need to construct it. In this embodiment, since the strength can be ensured by being laminated with the resin layer 3, it is possible to reduce the thickness of the glass plate. That is, since the weight is lighter than the conventional glass decorative plate, the thickness of the glass plate is preferably 4.0 mm or less. Moreover, it is more preferable that it is 3.0 mm or less. Thus, since the glass decorative plate can be thinned, the area of the glass decorative plate of the present embodiment is not particularly limited, but when it is 1 m ² or more, it can be reduced in weight as compared with the conventional glass decorative plate. Therefore, it is effective. Furthermore, it is effective when it is 2 m ² or more. In addition, because the glass decorative panel can be reduced in weight, it has traditionally been affixed firmly to the base material with an adhesive to prevent falling off. It becomes possible.

  The glass plate 2 is preferably in close contact with the design layer 4. When the design layer 4 is viewed through the glass plate by adhering, the glass decorative plate has a sense of depth and luxury, and is excellent in aesthetics. Further, the visible light transmittance of the glass plate 2 (obtained in accordance with JIS R3106) is preferably 60% or more, and more preferably 70% or more.

  In addition, in order to provide a texture on the surface of the glass plate 2, the glass plate 2 may be subjected to a texture treatment by post-processing such as frost processing on the surface.

  The glass plate 2 can be manufactured by a known method. That is, it is manufactured by cutting glass formed into a ribbon shape by a float method, a fusion method, a downdraw method, a roll-out method or the like.

  The glass plate 2 may have a compressive stress layer on the surface layer. When the glass plate 2 is tempered, the glass plate 2 becomes a tempered glass plate. A tempered glass sheet that has been subjected to a tempering treatment is preferred because it is less likely to break compared to a case in which no tempering treatment is performed. The tempered glass plate includes a compressive stress layer on the surface layer, that is, a front surface layer and a back surface layer having residual compressive stress, and an intermediate layer formed between the front surface layer and the back surface layer and having residual tensile stress. The residual compressive stress decreases as it goes from both ends in the thickness direction of the tempered glass plate to the inside, and a residual tensile stress is generated inside the tempered glass plate.

  The end surface of the tempered glass plate may be continuously covered with residual compressive stress on the front surface layer and the back surface layer. It is preferable that the end face of the tempered glass plate is covered with residual compressive stress because it is difficult to break against impact. The end face of the tempered glass plate may not be covered with residual compressive stress, and the end face of the intermediate layer may be exposed on the end face of the tempered glass plate. In that case, it is preferably covered with a cover material such as resin.

  The tempered glass plate is produced by applying a tempering treatment to cause residual compressive stress on the front and back surfaces of the glass plate. The tempered glass plate may be either a chemically tempered glass obtained by a chemical tempering treatment such as an ion exchange method or a physical tempered glass obtained by a physical tempering treatment such as an air cooling tempering method. If it is a chemical strengthening process, even if it is a glass plate with thinner plate | board thickness, the value of the residual compressive stress of a surface layer or a back surface layer can be enlarged. For example, the residual compressive stress value of the surface layer is preferably 300 MPa or more, and more preferably 400 MPa or more. In the case of chemically strengthened glass, the thickness of the compressive stress layer may be 50 μm or less, or 40 μm or less.

  In the ion exchange method, the front and back surfaces of a glass plate are ion-exchanged, and ions having a small ion radius (for example, Li ions and Na ions) contained in the glass are replaced with ions having a large ion radius (for example, K ions). Thereby, a residual compressive stress can be produced in the surface and back surface of a glass plate. In the ion exchange method, ion exchange is performed by immersing a glass plate in a high-temperature treatment solution.

  The air-cooling strengthening method rapidly cools the glass plate at the temperature near the softening point from both sides, and creates a temperature difference between the front and back surfaces of the glass plate and the inside of the glass plate. Residual compressive stress can be generated. Since the physical strengthening method such as the air cooling strengthening method takes several seconds to several tens of seconds for the strengthening process, the productivity is much superior to the chemical strengthening method such as the ion exchange method.

  A design layer 4 is formed between the glass plate 2 and the resin layer 3. The design layer 4 is formed, for example, by applying a paint containing a color pigment to the surface of the glass plate 2 and drying and curing. Examples of the paint include acrylic resin paints. Acrylic resin-based paints have high adhesion and are excellent in weather resistance and corrosion resistance. Moreover, it is preferable at the point that a finish is beautiful. The design layer 4 is not particularly limited as long as it can provide design properties. For example, the design layer 4 may be a melamine resin-based paint or an epoxy resin-based paint, and the color pigments may have various colors. The design layer 4 may be a mirror on which a metal is deposited.

  The coating method of the paint is not particularly limited, and for example, a roll coating method, a spray coating method, a dip coating method, a flow coating method, a screen printing method, a spin coating method and the like are used.

  Moreover, you may affix the design layer 4 shape | molded on the glass plate 2 with the adhesive agent etc. instead of the coating material. In that case, the design layer 4 formed into a sheet shape may be a single color or a plurality of colors, or a pattern such as a natural stone tone or a brick tone may be formed.

  The resin layer 3 has a thickness of 1.5 mm or more. When the thickness of the resin layer 3 is 1.5 mm or more, sufficient strength can be obtained when the resin layer 3 is laminated with the glass plate 2. Further, when the thickness of the resin layer 3 is 2.0 mm or more, since it is rigid, handling during construction becomes easy. More preferably, it is 3.0 mm or more. Moreover, since it is equivalent to the plate | board thickness of the conventional glass decorative board, since the thickness of the resin layer 3 is 8 mm or less, since the construction to a wall surface does not require a special operation | work like the past, it is preferable. Moreover, it is more preferable that it is 6 mm or less. The shape of the resin layer 3 is preferably the same as that of the glass plate 2 in plan view.

  Furthermore, the resin layer 3 can suppress the breakage of the glass plate 2 due to an impact or a fire, and can prevent the glass fragments from being scattered when the glass plate 2 is broken. Particularly, it is preferable that the resin layer 3 is made of a foamed resin because it is lightweight. Moreover, it is also preferable that the resin layer 3 becomes a buffer layer so that unevenness of the wall surface can be absorbed during construction on the wall surface.

  The resin layer 3 may be a plate-like member, or may be integrally formed on the glass plate 2 by injection molding or extrusion molding. When the resin layer 3 is a plate-like member, an adhesive or a pressure-sensitive adhesive (hereinafter referred to as “glass layer 2”) and the plate-like resin layer 3 are interposed between the glass plate 2 and the resin layer 3. , Adhesive, including pressure-sensitive adhesive). The adhesive may be applied to the entire surface of the resin layer 3 or a part thereof. It is advantageous to apply the adhesive to the entire surface because the glass plate is difficult to break. Further, an adhesive may be applied to the design layer 4 of the glass plate 2. As the adhesive, a general architectural sealant can be used, and examples thereof include a modified silicone sealant, an acrylic adhesive, and a synthetic rubber adhesive. The adhesive may be in the form of a sheet such as a double-sided tape. Moreover, it is suitable as a building material that an adhesive agent selects a material and application quantity so that nonflammability may become high.

  When the resin layer 3 is integrally formed on the glass plate 2, the glass plate 2 on which the design layer 4 is formed is placed in a mold and the resin is injected onto the design layer 4 to be integrally formed. In the case of extrusion molding, the resin is supplied from the extrusion mold onto the design layer 4 of the glass plate 2 and is integrally molded. If necessary, the resin layer 3 may be integrally formed after applying an adhesive or an undercoat (primer) such as a silane coupling agent to the glass plate 2 side.

  The total thickness of the glass plate 2 and the resin layer 3 is preferably 2.5 mm or more and 10 mm or less. When it is 2.5 mm or more, sufficient strength is obtained, and the glass plate 2 is hardly broken. In addition, the glass decorative plate often has a large area, and the workability is enhanced due to the rigidity. Sufficient rigidity is obtained by being 2.5 mm or more, and workability is good. Preferably, it is 3.0 mm or more, more preferably 4.0 mm or more. Moreover, since it is equivalent to the plate | board thickness of the conventional glass decorative board because it is 10 mm or less, since construction to a wall surface does not require a special operation | work similarly to the past, it is preferable. Moreover, it is more preferable that it is 8.0 mm or less.

  The Shore A hardness of the resin layer 3 is 10 or more and 60 or less. In addition, the Shore A hardness said by this application is based on the measured value of a durometer (Asker rubber hardness meter A type made from Asker). An indenter (pushing needle) is pushed into the surface of the object to be measured and deformed, and the amount of deformation (pushing depth) is measured to obtain an average value of at least four locations. When the resin layer 3 is thin and soft, measurement is performed with the resin layers superimposed so that the thickness is 6 to 12 mm. If the Shore A hardness is 10 or more, workability is good because of sufficient rigidity. Preferably it is 20 or more, More preferably, it is 30 or more. Further, if the Shore A hardness is 60 or less, it has sufficient shock absorption, so that even if the glass plate 2 receives a strong impact, it is difficult to break. Preferably it is 50 or less.

  The resin layer 3 of the present embodiment needs to be an elastic body having a predetermined elasticity in order to absorb an impact when an object collides with the glass plate 2, for example. However, if the elasticity is too great, the glass plate 2 may be locally bent and damaged when subjected to a strong impact. That is, the resin layer 3 needs to have a Shore A hardness that allows sufficient shock absorption and does not increase the amount of deformation of the glass plate 2.

  Therefore, the resin layer 3 may be a foamed resin. Since it is a foamed resin, the resin layer 3 can be easily controlled to have the Shore A hardness described above, which is preferable in production. That is, by changing the expansion ratio, the Shore A hardness can be easily controlled, and the resin layer 3 can be easily set to the required Shore A hardness according to the place where the decorative board 1 of the present embodiment is applied. It becomes possible.

The resin layer 3 may be a foamed polyethylene resin, a foamed urethane resin, or a foamed rubber. Since these resins are difficult to burn, it is preferable because it is easy to obtain a non-combustible material as a building material. Moreover, since it can be made to foam, since it can control easily as above-mentioned Shore A hardness, it is preferable on manufacture.
The glass plate 2 may have a functional layer that adds a special function to the decorative plate on the surface opposite to the resin layer 3. Examples of the functional layer include an antifouling film, an antibacterial film, and an antifogging film.
The antifouling film has an effect of reducing the adhesion of fingerprints or making it difficult to get dirt. In particular, when the decorative plate 1 is directly touched by a hand, a fingerprint is attached to the glass plate 2 to impair the design, and therefore it is preferable to have an AFP (Anti-Finger Print) function for reducing the adhesion of the fingerprint. In the AFP function, an AFP agent is attached to the glass plate 2 to form an AFP film on the glass plate. Examples of the AFP agent include fluorine-containing organosilicon compounds. Any fluorine-containing organosilicon compound can be used without particular limitation as long as it imparts antifouling properties, water repellency and oil repellency. The molecular weight of the AFP agent is preferably 3,000 to 10,000, more preferably 3,000 to 8,000, and still more preferably 3,000 to 6,000. When the molecular weight of the AFP agent is 3,000 or more, flexibility is imparted to the molecular structure, and scratch resistance and surface slip properties can be obtained. Moreover, when it is 10,000 or less, sufficient reactive groups per molecule of the AFP agent can be secured, and adhesion with the surface of the glass plate can be secured.
The antibacterial film is formed by attaching an antibacterial agent that exhibits antibacterial properties to the glass plate 2. Antibacterial agents include natural antibacterial agents such as wasabi, metal antibacterial agents such as copper and silver, and oxide antibacterial agents such as titanium oxide. In particular, a solution containing silver is applied to a glass plate to form a silver film, and heat treatment is performed on the glass plate on which the silver film is formed, thereby diffusing silver ions from the surface of the glass plate to the inside. It is preferable in terms of sustainability.
The anti-fogging film is provided with a water-absorbing resin layer on the surface of the glass plate 2 and absorbs and removes fine water droplets formed on the surface of the glass plate, thereby preventing the surface of the glass plate 2 from being fogged and having a design property. Has the effect of maintaining The antifogging film includes, for example, a base layer and a water absorption layer. An underlayer is a layer for making it difficult to peel a water absorption layer from a glass plate, for example, is obtained by apply | coating the composition containing a silane coupling agent to a glass plate, and making it react. The water-absorbing layer is obtained by applying a composition containing a raw material component of a cured resin selected from a cured epoxy resin, a urethane resin, and a crosslinked acrylic resin on the base layer and reacting.

  The periphery of the glass plate 2 and the resin layer 3 may be covered with a reinforcing material. FIG. 2 is a schematic cross-sectional view in which the reinforcing material 5 is attached to the end face of the decorative board 1. The reinforcing material 5 is formed in a frame shape around the decorative board 1. The reinforcing material 6 does not need to be seamlessly formed in a frame shape, and may be separated for each side. The reinforcing material 6 does not need to cover all the sides of the decorative board 1, and may cover at least one side. The reinforcing material 6 is made of, for example, a vinyl chloride resin. Since the decorative board 1 is covered with the reinforcing material 6 to protect the end face of the glass decorative board during construction, it is difficult to break, which is preferable in terms of workability.

The reinforcing material 5 has an anchor 6, and the reinforcing material 5 may be fixed to the decorative board 1 by inserting the anchor 6 into the resin layer 3. When the decorative board 1 is rectangular, the anchor 6 is provided in one or more places on each side, preferably in a plurality of places. For example, as shown in FIG. 2, the anchor 6 is inserted into and engaged with the resin layer 3 of the decorative board 1. The reinforcing material 6 is fixed to the decorative board 1 by the anchor 6 being engaged with the resin layer 3. The reinforcing material 5 may be fixed to the end face of the decorative board 1 with an adhesive. Fixing the reinforcing material 5 to the decorative board 1 with the anchor 6 is preferable because it can eliminate the time for curing the adhesive. Moreover, you may use together the anchor 6 and an adhesive agent. In that case, the anchor 6 functions as a temporary fixing, and the displacement of the reinforcing material 5 before the adhesive is cured can be prevented.
Although the example which used the glass plate as a plate-shaped body was demonstrated above, the resin board and ceramic board which have brittleness instead of a glass plate may be sufficient. Examples of the brittle resin plate include a melamine resin plate, an acrylic resin plate, a polycarbonate resin plate, and a vinyl chloride plate. Examples of the ceramic plate include a ceramic member such as a tile. The plate-like body may be made of stone. These brittle plate-like bodies can also be suitably used for the decorative board of the present invention.
In addition, the design layer may be provided with designability by, for example, template glass in which a pattern is provided on the surface of the plate-like body by unevenness or the like.

(Impact test)
The impact test performed on the glass decorative plate of one embodiment of the present invention will be described below. In Examples and Comparative Examples shown in Table 1 below, soda lime glass (ASA manufactured by Asahi Glass Co., Ltd.) having a length of 300 mm and a width of 300 mm was used as a glass plate. Moreover, the foaming polyethylene resin board which changed the foaming magnification of the chemically crosslinked polyethylene foaming resin (SUNPELICA (trademark) by Sanwa Kako Co., Ltd.) as the resin layer and adjusted to desired Shore A hardness was used. An adhesive (POS Seal Multi (registered trademark) manufactured by Cemedine Co., Ltd.) was applied to the entire surface of the glass plate, and the resin layer was bonded. Various glass decorative plates were prepared by changing the thickness of the glass plate, the thickness of the resin layer, and the Shore A stiffness as shown in Table 1. General-purpose silicone rubber plate (Misumi silicon rubber sheet) for resin layer with Shore A hardness 65-70, and general-purpose acrylic resin plate (Acrylite E (Mitsubishi Rayon Co., Ltd.) for resin layer with Shore A hardness 80-85 Registered trademark)). Moreover, the glass plate without a resin layer was evaluated as another comparative example. In addition, the design layer was abbreviate | omitted for the impact test and the glass decorative board was produced.

  In the impact test, in the bending and impact test method for building boards (JIS A1408), a gypsum board is set on sand, and a steel ball having a weight of 225 g is placed on a glass decorative plate placed on the gypsum board. It was carried out by dropping from a height of 75 cm and 100 cm. The results are shown in Table 1. In Table 1, the case where the probability that the glass decorative plate was not broken when the steel ball was dropped from a height of 75 cm was 50% or more was designated as “Δ”, and the case where it was less than 50% was designated as “X”. Moreover, the case where the probability that the glass decorative plate was not damaged when the steel ball was dropped from a height of 100 cm was 80% or more was evaluated as “◯”. The probability of each example was calculated from the results of testing with 2 to 5 samples, and an evaluation of “◯”, “Δ”, or “×” was performed. In Table 1, a blank part indicates no corresponding sample.

From the above results, the decorative board in which the resin layer thickness is 1.5 mm or more and the Shore A hardness of the resin layer is 10 or more and 60 or less is excellent in impact resistance, is hard to break, especially glass Glass having a plate thickness of 4.0 mm when the plate thickness is 0.5 mm or more, the resin layer thickness is 1.5 mm or more, and the Shore A hardness of the resin layer is 10 or more and 60 or less. It has been found that it has a strength equal to or higher than that of a glass decorative plate made of only a plate.
(Exothermic test)
An exothermic test performed on the glass decorative plate of one embodiment of the present invention will be described below. Soda lime glass (ASA manufactured by Asahi Glass Co., Ltd., 300 mm long, 300 mm wide, two types of plate thickness 1.1 mm and 2.0 mm) as a glass plate, and adhesive (POS Seal Multi (registered trademark) manufactured by Cemedine) ) Is applied to the entire surface, and a chemically cross-linked polyethylene foamed resin (SUNPELICA (registered trademark) manufactured by Sanwa Kako Co., Ltd., having a thickness of 3 mm, a Shore A hardness of 30 to 32 and 25 to 27, is available in two types. .) Were bonded together to change the conditions of the thickness of the glass plate and the Shore A hardness of the resin layer, and five types of four decorative glass sheets were produced.

An electric heater is installed facing the surface of the produced glass decorative board, radiant heat of 50 kW / m ² is applied to the glass decorative board from the electric heater, and the spark plug is installed in the vicinity of the glass decorative board. An exothermic test was conducted to measure the calorific value of the glass decorative board.

In the exothermic test, 20 minutes after the start of heating, (1) the total calorific value is 8 MJ / m ² or less, and (2) the maximum heat generation rate does not exceed 200 kW / m ² continuously for 10 seconds or more. And (3) three evaluations were made: no cracks and holes penetrating to the back side, which is harmful to fire prevention. All the glass decorative boards in the example of the embodiment described above cleared the above three evaluation items. As a result, it was found that the glass decorative board of this example is a highly incombustible building material.

According to the present invention, it is possible to provide a decorative plate that is difficult to break even when a large impact is applied, and that does not scatter even if it is cracked, and is widely used as a decorative plate for various uses such as buildings and stores, including for general housing.
