Description

      The present invention relates to a decorative board that is transparently painted for use as ornamental ornaments, furniture fixtures, interior parts, or piano plates.

Conventionally, there are known decorative boards used as ornamental ornaments etc. in which textiles etc. are sandwiched, and piano boards etc. that are improved in color decoration by inserting paper or cloth inside. (For example, Patent Document 1, Patent Document 2, etc.).
As shown in FIG. 2, for example, a flat fabric 2 having a pattern formed on a flat substrate 1 made of, for example, a wooden plate or a glass plate, and a flat object 2 such as a photograph are attached, and a polyester resin coating or the like is applied from the upper surface thereof. Is applied to form a polyester resin layer 4 and the entire structure is sealed.

      However, in the conventional decorative plate as described above, the thickness of the polyester resin layer 4 is increased and the strength is improved by the amount of the flat object 2 such as a woven fabric, but the flexibility is reduced. Thus, there have been problems such as cracks (cracks, cracks, etc.) on the painted surface, or a decrease in transparency due to deterioration of the polyester resin layer 4 due to aging.

The present invention has been devised to solve the above problems. The present invention provides a decorative plate that is resistant to cracks (cracks, cracks, etc.), has excellent durability, and can suppress the decrease in transparency due to secular change, and can maintain high vividness and depth of colors and the like. There is.
The invention according to claim 1 is a substrate, a planar object affixed on the substrate, a transparent polyester resin layer formed on the planar object, and a transparent polyurethane formed on the polyester resin layer. A decorative board characterized by having a laminated structure including a resin layer.

      By the said device, it is hard to produce a crack (a crack, a crack, etc.), is excellent in durability, and can also suppress the fall of the transparency by secular change.

Sectional drawing which shows an example of the decorative board which concerns on this invention. Sectional drawing which shows an example of the conventional decorative board.

Hereinafter, an example of a decorative plate according to the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the decorative plate 10 includes a substrate 1, a planar object 2 attached on the substrate 1, a transparent polyester resin layer 4 formed on the planar object 2, and the polyester resin. The whole is integrally formed as a laminated structure including the transparent polyurethane resin layer 5 formed on the layer 4.

      Here, a transparent sealer coating layer 3 is preferably interposed between the planar object 2 and the polyester resin layer 4. By interposing this sealer coating layer 3, the unevenness on the upper surface of the planar object 2 can be filled with the sealer coating layer 3 to smooth the surface, and the adhesion to the upper polyester resin layer 4 can be improved. .

      The area of the planar object 2 is slightly smaller than that of the substrate 1, and the outer peripheral part of the peripheral part of the planar object 2 is in direct contact with the upper surface of the substrate 1 and the lower surface of the peripheral part of the polyester resin layer 4 Thus, the area where the flat object 2 is located is hermetically sealed so that moisture and air that cause deterioration do not enter the inside.

      Here, as the substrate 1, a flat wooden plate, a glass plate, a plastic plate, or the like can be used. Further, as the planar object 2, a relatively planar object such as a woven fabric, a photograph, a painting, paper, or the like with a pattern or the like can be used. This thickness is, for example, about 0.2 mm to 1.5 mm. The thickness of the sealer coating layer 3 is, for example, about 20 to 30 microns. The polyester resin layer 4 has a thickness of about 350 to 600 microns, and the polyurethane resin layer 5 has a thickness of about 100 to 150 microns.

In addition, the term “transparent” means that the pattern or the like of the flat object 2 can be visually recognized from the upper surface of the decorative board 10 in this specification, and the transparency is such that the pattern or the like can be visually recognized outside the complete transparency. It only has to have, and coloring etc. may be given.
The decorative plate 10 here can be used as a decorative ornament such as a decorative panel installed in a room, a furniture fixture, an interior part, a piano plate, or the like.

      As described above, by forming the polyurethane resin layer 5 on the polyester resin layer 4, cracks (cracks, cracks, etc.) are easily generated only by the polyester resin layer 4 having a high hardness like a conventional decorative plate. However, a polyurethane resin layer 5 having a lower hardness or softer than the polyester resin layer 4 is formed thereon to form a double structure, so that the polyurethane resin layer 5 absorbs external impact force and cracks. It is possible to improve durability such as preventing the occurrence of (cracks, cracks, etc.), and to prevent the entire deterioration due to secular change and to suppress opacity. Therefore, the vividness and depth of the color of the flat object 2 can be maintained high.

Next, an example of the manufacturing process of the decorative board 10 will be specifically described.
[Step 1]
The surface of the substrate 1 made of glass, wood board or the like is polished.
[Step 2]
A flat object 2 such as a woven fabric, a cloth or a band is attached to the substrate 1 with an adhesive.
For example, Bond (registered trademark) is used as the adhesive. At this time, air or the like should not be contained inside.

[Step 3]
The sealer coating layer 3 is formed by applying sealer coating from above the adhered flat object 2 using urethane resin paint. The sealer coating layer 3 may be omitted.
[Step 4]
After the above sealer coating, it is dried by leaving it at room temperature for about 2 to 3 hours.
[Step 5]
Next, a polyester resin coating is applied on the sealer coating layer 3 to form a polyester resin layer 4.

[Step 6]
Next, after the polyester resin paint is applied, the polyester resin paint is left to stand at room temperature for about 24 hours to be dried.
[Step 7]
Next, the surface of the dried polyester resin layer 4 is smoothed by paper polishing.

[Step 8]
Next, a polyurethane resin coating is applied on the polyester resin layer 4 to form the polyurethane resin layer 5.
[Step 9]
Next, after the polyurethane resin coating is applied, it is dried by leaving it at room temperature for about 24 hours.
[Step 10]
Next, the surface of the polyurethane resin layer 5 is paper-polished to give a mirror surface, and further buffed to complete the product.

      The decorative board 10 formed as described above has excellent durability without cracks (cracks, cracks, etc.), and can also suppress a decrease in transparency due to secular change.
