FIELD OF THE INVENTION The present invention is a novel cosmetic material,
TECHNICAL FIELD The present invention relates to a plate glass / a veneer backing sheet / a plate glass laminate, a plate glass / a double-sided veneer-attached sheet / a plate glass laminate, and a plate glass / a veneer backing sheet / a substrate laminate, which are useful as furniture furniture and office supplies.

2. Description of the Related Art Conventionally, as a decorative material whose front and back surfaces are transparent,
For example, as shown in FIG. 6, a veneer 14 (decorative veneer) of a name tree
For example, a decorative material 12 in which a transparent sheet 13 made of acrylic resin is embedded is developed and used. However, this type of decorative material 12 generally lacks in gloss and luster on the front and back sides due to the properties of the resin, and is easily deteriorated by light and heat, and has the drawback of insufficient weather resistance and heat resistance. Had. Further, the decorative material 12 is conventionally usually manufactured by a method of embedding a projecting plate 14 having a predetermined thickness in a molten resin in a shallow container and then solidifying the resin.

[0003]

However, in this manufacturing method, it is extremely difficult to make the decorative material 12 so that the projecting plate 14 is positioned in parallel to the front and back surfaces 15a and 15b of the decorative material 12, In addition, the veneer 14 in the manufacturing process
In the case of embedding, the air was apt to be entrapped in the molten resin, and as a result, the resin was solidified while leaving the bubbles 16 as it was, and a cosmetic material product having bubble defects was often obtained. Remaining air bubbles in the decorative material not only significantly lowers the design value of the decorative material, but also adversely affects the durability thereof.

Further, as a surface coating for a high-quality finish of a veneer-attached decorative board, coating with a polyurethane resin or a polyester resin is performed. This coating is performed by solidifying a molten resin on the surface of the decorative board and laminating resin layers. However, since the resin lacks gloss and luster due to its nature, the obtained decorative board was not able to clearly recognize the grain of the veneer surface. The resin also has a drawback that it is easily deteriorated by light and heat. Furthermore, it is very difficult to laminate this resin layer to a uniform thickness and to have a smooth surface. This is because as the thickness of the resin layer increases,
It becomes more difficult.

On the other hand, among furniture furniture, a glass plate placed on a veneer on the surface of the furniture has been conventionally manufactured and sold. However, in such furniture furniture, the glass plate and the veneer are not in close contact with each other, and the grain on the surface of the veneer cannot always be clearly seen through the glass plate.

In general, in order to bring the glass plate and the projecting plate into close contact with each other, it is conceivable to interpose an adhesive between them and press them together. However, since the projecting plate is microscopically porous and has a large air content, if this is simply laminated with the glass plate and pressure-bonded to form one laminated body,
Air in the veneer may escape insufficiently, and bubbles may remain between the glass plate and the veneer. Such remaining air bubbles not only lower the design value of the laminate, but also pose a problem in terms of durability such as peeling between the glass plate and the projecting plate when heated. In particular, when glass plates are laminated on both sides of the projecting plate, the remaining bubbles become remarkable, and the above problem becomes more serious.

Further, when a liquid adhesive is used to adhere the glass plate and the veneer to each other, since it contains a large amount of solvent, the phenomenon of whitening, that is, the solvent volatilizes and the glass plate evaporates after a long period of time. It often happens that the grain of the veneer is clouded and the grain of the veneer looks white and turbid, which is a problem in that the design value decreases with time. In addition, the residual solvent accelerates the peeling between the glass plate and the veneer plate and deteriorates the durability.

Further, the veneer plate is generally colored to improve its quality. However, since the veneer is a very thin sheet material of natural wood, it is considerably difficult to color the veneer directly.

The present invention has been made in consideration of the above circumstances, and a first object thereof is to solve the above-mentioned various problems of the related art and to visually recognize the veneer grain more clearly. It has high design value and can maintain its value over time, such as no generation of bubbles and virtually no residual solvent and no whitening, and it is also excellent in durability and weather resistance, and is colored. Another object of the present invention is to provide a sheet glass / sheet veneer backing sheet / sheet glass laminated product in which an easily-protruded sheet can be arranged parallel to the front and back surfaces.

A second object of the present invention is a plate glass / double-sided veneer stuck sheet / plate glass laminated product which has the same characteristics as those described above and enables the grain of the veneer to be clearly recognized from both sides. To provide.

Further, a third object of the present invention is to provide the same characteristics as in the case of the above-mentioned laminated product such that the grain of the veneer can be visually recognized remarkably and has a surface parallel to the veneer. Plate glass that has a unique appearance that does not exist in conventional products
It is to provide a veneer backing sheet / base material laminate.

[0012]

Sheet glass according to the invention /
The veneer-lined sheet / plate glass laminated product is a novel decorative material characterized by being formed by laminating two sheet glass sheets on both sides of the veneer-lined sheet via adhesive films respectively.

Further, the plate glass / double-sided veneer stuck sheet / plate glass laminated product according to the present invention is characterized in that two plate glasses are arranged on both sides of the double-sided veneer stuck sheet with an adhesive film, respectively, and laminated and formed. It is a new cosmetic material that does.

Further, in the laminated glass / plate backing sheet / base material laminate according to the present invention, the plate glass is arranged on the side of the surface of the backing sheet of the veneer via an adhesive film, and the base material is located on the side of the backing surface of the backing sheet of the veneer. It is a novel decorative material characterized in that it is formed by laminating and arranging it via an adhesive film or a liquid adhesive.

The plate glass used in the present invention may be any plate-shaped glass having a uniform thickness and having the front and back surfaces kept parallel to each other. Conventional plate glass, tempered plate glass, and polished plate glass which have been conventionally used. Etc. can be applied to the present invention. Further, the plate glass having a thickness of 0.5 to 10 mm is suitable. Further, in order to maintain good adhesiveness with the adhesive film with time, it is preferable to apply plate glass that has been previously treated with a suitable primer before lamination. It is more preferable that the primer has high transparency and good adhesion.

Further, in the present invention, a veneer lined sheet is used. This is because if the veneer itself is adopted, the veneer will be damaged at the time of hot pressing in the manufacturing process of the laminated product with the sheet glass, and the commercial value will be lost. That is, in order to create a high adhesion state between the plate glass and the veneer, it is necessary for the adhesive to sufficiently penetrate into the veneer and remove the air bubbles inside the veneer to the outside of the system. It is necessary to carry out hot pressing under the conditions of considerably strong pressure and temperature as described below. However, under such conditions, unless the veneer is lined with any paper or the like, there are frequent damage defects in which the veneer is divided into several pieces due to the pressure of the softened adhesive to flow. It will happen. In addition, the veneer-lined sheet is more advantageous than the veneer itself in terms of preventing damage to the veneer during handling and preventing the veneer from wrinkling. Therefore, in the present invention, the veneer itself is not used, but the veneer backing sheet having the backing material adhered thereto is used.
The veneer and the backing material may be conventional ones. Specifically, the veneer is made of various natural wood, such as cypress,
Nara, Kusunoki, Keyaki, Tochigi, Kihada, Shioji, Taboki, Japanese timber, etc., teak, rosewood, mahogany,
Birdseye maple, walnut, zebrawood,
Imported materials such as Kotan, Abodora, Dao, Satin Wood, Brazilian Rose, for example, 0.1 to 0.6mm
The one cut to a certain thickness is used. The veneer used preferably has a water content of about 12% or less, and the thicker the plate, the lower the water content. The backing material is, for example, a sheet-like material such as non-woven fabric, Japanese paper, kraft paper, resin-impregnated paper, cloth, felt, flock, plastic, etc., and transparent ones are more preferable. Although the backing material varies depending on the material and the purpose, a backing material having a basis weight of about 20 to 200 g / m ² is usually used. The veneer and the backing material are adhered by a hot pressing method using a thermosetting or thermoplastic adhesive, and the adhesive is preferably transparent.

Further, the double-sided veneer-attached sheet used in the present invention is formed by hot pressing, in which an adhesive film or a base cloth coated with an adhesive in advance is placed between two veneers. The base cloth includes, for example, paper, non-woven fabric, cloth, plastic film and the like. The above-mentioned one is used as the projecting plate.

By using the above-mentioned veneer backing sheet or double-sided veneer pasting sheet, it is possible to prevent the veneer from wrinkling and prevent the veneer from being damaged during handling. Also,
When the veneer is colored, it can be easily passed through a roll coater or the like in the form of a veneer backing sheet or a double-sided veneer-attached sheet.

The substrate used in the present invention is not particularly limited, and examples thereof include wood-based ordinary plywood, special plywood such as fiberboard and particle board, metal plate or plastic plate.

Further, the adhesive film used in the present invention may be any material as long as it has the ability to bond the veneer backing sheet or the double-sided veneer sticking sheet and the plate glass or the base material by molding, and the veneer backing sheet and the base material can be bonded together. It is not necessary to use a transparent one for adhesion, but a transparent one is used for other adhesion. Examples of the material of the adhesive film include transparent materials such as polyolefin, ionomer, and nylon-12, and opaque materials such as phenol resin. The thickness of the film varies depending on the type of the veneer and the adhesiveness of the film, but is about 3
It is preferably 0 to 160 μ. The particularly preferred adhesive film in the present invention is selected from the group consisting of polyolefins, ionomers and nylon-12 based adhesive films. When the adhesive film of this group is used, the adhesive sufficiently penetrates into the veneer in the press molding to eliminate the air bubbles inside the veneer from the outside of the system, whereby the plate glass and the veneer lining sheet can be adhered to each other. Therefore, such adhesion makes it possible to visually recognize the wood pattern design of the internal veneer through the plate glass as a very clear and deep (deep feeling) product. Such a design cannot be obtained by simply stacking plate glass on a veneer.
However, even if an adhesive other than the above-mentioned group is used, the laminated product obtained cannot be visually recognized as having a clear and deep (deep feeling) wood grain design of the internal veneer. Generally, when a conventional wood adhesive such as a rubber-based adhesive is used, the adhesive penetrates only insufficiently into the veneer and eliminates the air inside the veneer even after the process of thermal compression. Because of the imperfections, the resulting laminate has a veneer grain that appears to be blurry, and is merely a design as if the plate glass was simply placed on the veneer.

The plate glass / plate backing sheet / plate glass laminated product, plate glass / double-sided plate laminated sheet / plate glass laminated product and plate glass / projected plate laminated product of the present invention are each subjected to hot press molding while the pressing pressure is kept constant during molding. It can be surely manufactured by a method of performing cold press molding subsequently, that is, a hot cold flat press method.

By using a veneer backing sheet and a double-sided veneer-attached sheet, and adopting a manufacturing method in which a laminated body of these sheets and the sheet glass are bonded and integrated by press-compression, there are problems such as cracking of the sheet glass and breakage of the sheet veneer. Laminates of the present invention can be produced without happening. Moreover, by using these sheets, for example, the length is 2000-3000m.
There is an advantage that a large-area laminated product having an m and a width of 500 to 2000 mm can be manufactured.

Further, the plate glass / veneer lined sheet / base material laminate of the present invention is a method for cold press molding the above-mentioned plate glass / veneer laminate product and the base material, and hot press molding of the veneer backing sheet and the base material. Alternatively, there is a method in which a veneer / base material laminate is manufactured in advance by cold press molding, and then hot press molding is performed on the sheet glass and the veneer / base material laminate, but the former method is less likely to cause warpage of the laminate. It is also preferable because the residual stress on the plate glass is small.

[0024]

The plate glass is remarkably excellent in transparency and light reflection characteristics as compared with acrylic resin and the like. The laminated product of the present invention is one in which this plate glass and the veneer lining sheet etc. are brought into close contact with each other by adopting an adhesive film (the bubbles inside the veneer are eliminated to the outside of the system by the adhesive sufficiently permeating into the veneer). It is possible to more clearly and clearly reflect the grain of the veneer (grain, grain, etc.) due to the optical properties of the glass. Give the viewer a color tone. That is, the wooden design of the internal veneer can be visually recognized as a very sharp and deep (profound feeling) design that cannot be obtained by simply stacking glass sheets on the veneer. .

Moreover, in the present invention, since the adhesive film is used in addition to the plate glass and the veneer backing sheet,
That is, since the veneer backing sheet is made parallel to both the front surface and the back surface of the laminated product by using the material having the uniform thickness, a parallel laminated product having a constant thickness can be obtained.

Moreover, due to the smoothness of the surface of the adhesive film, air hardly remains between the film and the projecting plate or the plate glass during the pressure bonding, and even if it remains, it is easily expelled to the outside. Therefore, no residual bubbles are generated. This is in contrast to the fact that when a general liquid adhesive is used, bubbles may remain depending on the unevenness of the adhesive surface. Therefore, a laminated product having a very high design value can be obtained, and the presence of air bubbles does not lower the pressure-bonding strength of the laminated product and the durability is not deteriorated.

Moreover, since the adhesive film is a material which does not substantially contain a solvent, unlike a general liquid adhesive, the laminated product of the present invention can be manufactured even after a long period of production. The whitening phenomenon does not occur and the design value can be maintained over time. Further, the present laminated product does not cause deterioration in durability due to the residual solvent.

Further, by using the veneer backing sheet in the laminated product of the present invention, it becomes possible to repair the external defects of the veneer unit, such as cracks and voids. That is, in the case of cracks, the cracked portions can be repaired by joining them together and adhering to the backing material, and in the case of voids, repair can be done by filling the putty. Further, the veneer backing sheet can be easily passed through the roll coater, and the veneer can be colored, so that the veneer can be upgraded.

Further, by using the double-sided veneer stuck sheet in the laminated product of the present invention, the veneer can be repaired and the veneer can be colored in the same manner as the veneer backing sheet. Further, the plate glass / double-sided laminated veneer-attached sheet / plate glass laminated product using this allows the grain of the veneer to be visually recognized from both sides of the sheet.

Further, by using the laminated product of the present invention as the plate glass on both outer surfaces, it is possible to seal the periphery of the end portion, and this sealing can completely shut off moisture and oxygen.
Therefore, it is possible to delay the deterioration due to cracking of the veneer due to the movement of water and the discoloration due to the oxygen supply.

In this laminated product 5, first, a liquid adhesive 6 (acrylic emulsion adhesive, viscosity 2200 cp (30 ° C.), solid content 50%) is wetted on the surface of the cleaned plate glass 2 to a basis weight of 140 g / m ^2. (Dry basis weight of 70 g / m ² ) is uniformly spray-coated, and then the two glass sheets 2 and 2 are laminated on both sides of the veneer backing sheet 3 and then the laminated body is hot. It is placed in a press together with a paper cushion and hot-cold press molded. Specifically, the press temperature is 1.
Heat compression under the conditions of 25 ° C, pressing pressure 8 kg / cm ² and pressing time 8 minutes, and then continue pressing at the same pressing pressure until it is cooled to 60 ° C, after which the pressing pressure is released and the formed laminate It is manufactured by taking out the product 1. The adhesive 6 preferably has a low viscosity and a high fluidity, and the coating amount thereof is preferably 30 to 150 g / m ² in terms of solid content.

Only when the adhesive can be applied very uniformly, the generation of residual air bubbles in the laminated product can be eliminated, and in the laminated product 5 of the reference example, the presence of residual air bubbles is sometimes recognized. Except for the above, the finish and aesthetics were the same as those of Example 1.

Example 2 The laminated product 7 of Example 2 shown in FIG. 3 is different from that of FIG. 3 in that a double-sided veneer pasting sheet 8 is arranged in place of the veneer backing sheet 3.
A plate glass / double-sided veneer laminated sheet / plate glass laminated product having the same layer structure as in Example 1. This double-sided veneer-attached sheet 8 has a vinyl acetate adhesive applied to both sides of a book paper (basis weight of 30 g / m ² ).

Moreover, this laminated product 7 is a cosmetic material with a wider range of use, because the grain of the veneer can be seen very clearly from both sides.

Reference Example 2 In the laminated product 9 of Reference Example 2 shown in FIG. 4, a normal plate glass 2 having a thickness of 2 mm is arranged on the surface of the veneer backing sheet 3 on the side of the veneer via a polyamide adhesive film 4 (thickness: 80 μ). It is then laminated and molded. The veneer backing sheet 3 was formed by hot-pressing a 0.25 mm thick wooden veneer into a 2 mm thick felt coated with a vinyl acetate adhesive [pressing temperature 110 ° C., pressing pressure 8 kg / cm ² , and pressing time 2 minutes. Conditions]. The press molding conditions for manufacturing the laminate 9 are the same as in Example 1.

The obtained laminated product 9 had a good finish as in Example 1, and the grain of the veneer could be visually recognized very clearly. It was dignified. No bubbles were generated or glass was broken.

Example 3 In the laminated product 10 of Example 3 shown in FIG. 5, the ordinary plate glass 2 having a thickness of 2 mm is attached to the veneer side of the veneer backing sheet 3 by the adhesive film 4.
And a 9 mm-thick ordinary plywood base material 11 is placed on the backing material side of the veneer backing sheet 3 via a water-based polymer-isocyanate liquid adhesive 6 and laminated. .

To explain this manufacturing method, the liquid adhesive 6 is applied to one side of the base material 11, the sheet glass / veneer backing sheet laminate 9 obtained in Example 4 is placed thereon, and this laminate is placed in a press machine. Then, a 2 mm thick paper cushion is inserted between the laminate and the hot plate of the pressing machine, and cold pressing is performed under the conditions of a press temperature of room temperature, a press pressure of 5 kg / cm ² , and a press time of 30 minutes.

The laminated product 10 thus obtained has a good finish, does not lose the sharpness of the grain of the veneer of the laminated product 9, and is free from the formation of bubbles, the breakage of glass and the breakage of the base material. It didn't happen at all.

Can be seen. That is, conventional products (including products in which plate glass is simply placed on top of a veneer)
It has a unique style and taste not found in. Moreover, such characteristics are maintained because the plate glass is not easily affected by light and heat.
In addition, this laminated product can seal the periphery of its end, and by this sealing, moisture and oxygen etc. to the veneer are blocked, and deterioration and discoloration of the veneer can be greatly delayed. Furthermore, by using the veneer backing sheet, it is possible to repair the veneer that is easily damaged, and it is easy to color the veneer. Further, the laminated product of the present invention, unlike the veneer-attached decorative plate, has an effect of not causing surface cracking defects.

Sheet glass of the present invention / sheet coated with double-sided veneer /
Since the sheet glass laminated product has the double-sided sliced veneer sheet sandwiched between the plate glasses, the grain of the sliced veneer can be clearly recognized from both sides of the laminated product, and the range of use of the laminated product is further widened. It is needless to say that this laminated product has the same performance as that of the above-mentioned laminated product in terms of the effects described above. For example, in this laminated product, the deterioration and discoloration of the veneer can be delayed by the seal around the end portion, and the veneer can be repaired and colored by using the double-sided veneer-attached sheet.

The plate glass / veneer lined sheet / base material laminate of the present invention is a product in which the plate glass and the veneer (or the veneer backing sheet) are laminated on the base material, and therefore the surface of the laminated product is smooth and is different from that of the veneer plate. It is parallel, and the grain of the veneer can be seen very clearly. This property also persists because plate glass is less susceptible to light and heat. It is needless to say that this laminated product has the same performance as that of the above-mentioned laminated product in terms of the effects described above. Further, this laminated product can be produced by previously producing a plate glass / veneer laminated product, and then laminated on a substrate. Therefore, by using the furniture furniture, the wall of a house, etc. as a base material and laminating the plate glass / veneer laminate product on the base material, a laminated product with the base material decorated can be easily obtained.

Furthermore, since all of the above three kinds of laminated products of the present invention use the plate glass, the veneer backing sheet and the adhesive film, there is no bubble generation and there is substantially no solvent remaining and whitening does not occur. It does not occur and has a high design value and can maintain its value over time, and since it does not cause the bad influence of bubbles and solvents, it has excellent durability and weather resistance. It has an excellent feature that no inconvenience occurs. In addition, the laminated product of the present invention has an advantage that the easily colored veneer plate can be arranged parallel to the front and back surfaces.
