Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] A surface makeup object having a surface decorative veneer stuck to its surface, mainly a construction material, a decorative board, furniture, fittings, etc. Regarding

[Prior art and its problems]

Conventionally, when manufacturing a surface-coated object having a surface decorative veneer stuck to the surface, mainly for making decorative materials, decorative boards, etc., furniture, fittings, etc., first, there is no coating to form the decorative layer. The veneer for surface makeup is adhered to the object to be makeup, and thereafter, the surface of the sheet-like object for surface makeup is coated by spray coating.

However, at this time, since the veneer for surface makeup has already been attached to the surface of the object to be coated, its coated surface is a curved surface, six sides on both sides of the surface, or an uneven portion. Since one painting process leads to a non-painting process, it is not an effective means in terms of equipment and labor costs.

Further, in the coating process, there is a large amount of paint loss due to spray coating, and since each surface and each portion to be coated are coated by different sprays, it is difficult to avoid the occurrence of color difference in each portion. I was throwing a problem in the finish.

Further, the color control of the spray and the paint for unifying the color tone of each paint in each spray for the purpose of reducing the color difference is extremely complicated and difficult, resulting in a decrease in productivity. Was there.

[Means to solve the problem and its action]

The cosmetic of the present invention has the following constitution in order to solve the problems of the prior art. That is, a paint that forms a paint film having an elongation of 7 to 250% and a film thickness of 3 to 500 μm is selected, and the paint is applied to a flat plate veneer raw material before being adhered to a subject. After that, this painted veneer raw material is attached to the object to be decorated.

The present invention, by adopting the above-mentioned configuration, does not cause cracks or cracks in the coating film even on the uneven surface portion of the object to be coated, and further, the coating process is simple and a coating film having a uniform color difference is obtained. It is what is done.

[Description of configuration]

 The configuration of the present invention will be described below.

In order to apply the surface makeup to the article 3 to be coated, the surface of the veneer for surface makeup is coated with a paint that forms a stretched coating film.

The to-be-coated article 3 mainly refers to structural members, plate-shaped bodies, rod-shaped bodies and other components of furniture and fittings, and the surface to be coated may have a curved surface.

The material of the object 3 to be coated is not particularly limited to wood, synthetic resin material, inorganic material, organic-inorganic composite material, metal and the like.

The surface decorative veneer 1a is an artificial veneer or a natural veneer, which is optionally pre-treated before painting, so that it can be laminated, lapped, or attached to the surface of the article 3 to be decorated. Is what is.

As a material, natural wood veneer or veneer laminated from natural wood such as cedar, cypress, chestnut, pig, zelkova, zelkova, teak, mahogany, rosewood, and hemlock are laminated to a thickness of 0.2 to 1.0 mm. An artificial veneer obtained by slicing can be used.

Stretched coating applied to the surface of the veneer for surface makeup 2
As the paint to form, liquid-type polyurethane resin paint, acrylic resin-based UV paint, alkyd resin paint, vinyl resin paint, nitrocellulose lacquer two-pack type epoxy resin paint, etc. are used. A coating material having a property of having a coating film elongation of 5% or more, preferably 7 to 250% within a range of 5 to 500μ is selected.

That is, as a result of various experiments, the present invention product has a coating film elongation of 7
It was also confirmed that the integrity of the coating film can be completely secured by selecting a coating film having a thickness within a range of ˜250% and a thickness within a range of 5 to 500 μ. That is, the thickness of the coating film is generally 5 to
It is about 500μ. In the present invention, the above-mentioned numerical values are selected by setting the film elongation suitable for this film thickness. That is, when the coating film has an elongation of 7 to 250% and a coating film thickness of less than 5 μm, when the surface-applied veneer coated with this coating is adhered to a decorative material, The coating film is liable to be broken, and the surface material is easily exposed due to the scratches on the surface, which causes a decrease in the surface cosmetic properties of the cosmetic product.

When the coating film elongation is in the range of 7 to 250% and the coating film thickness is 500 μm or more, when the surface-applied convex plate 1 with this coating is attached to the decorative material 3, the bending In the portion, a strong tension is generated in the outermost layer portion of the coating film 2, so that the coating film is more likely to be damaged than the portion, such as cracking or cracking.

On the contrary, the elongation of the coating is 7 within the range of coating thickness 5 to 500μ.
If the coating film is less than%, the rigidity is high and it becomes very brittle,
When the sheet material for surface makeup having this coating film is attached to a material to be coated, breakage of the coating film such as cracks and cracks is caused at the bent portion.

Also, the elongation of the coating film is 250% within the coating thickness range of 5 to 500μ.
If it is above, the flexibility of the coating film is too high and the coating film is easily scratched, and it is very difficult to handle in various steps such as a coating step and subsequent drying and curing, and not only surface cosmetic properties,
It is not preferable because it causes a decrease in productivity.
However, in practice, if the elongation of the coating film is 5% or more, there is no problem in use.

It is desirable that the coating material for forming a stretched coating film on the surface decorative veneer a is applied by using a roll coater, a curtain coater, or the like, which causes the loss of the coating material that has occurred during spray coating. At the same time, it is possible to obtain the decorative material 1 having a uniform color on the front surface without performing difficult color management.

Subsequently, the surface cosmetic sheet material 1 thus obtained
Is affixed to the surface of the article to be makeup 3.

The sticking of the surface decorative veneer is performed by laminating adhesion using a vacuum press, lapping, etc., depending on the shape of the material 3 to be adhered. Other methods and forms are not particularly limited, but for example, when a decorative plywood is obtained by lamination, when performing subsequent combing V groove processing, and when lapping a work material, surface makeup Since the coating film formed on the veneer plate is an elastic coating film, even if bending is performed, the coating film will not be damaged, such as cracks or cracks, at the bent portion, and surface makeup will be applied. It is possible to effectively exert the effect of being able to.

Thus, since the veneer for surface makeup, which has been previously coated, can be attached to the object to be coated, it is not necessary to separately coat each part of the decorative material as in the conventional case, and the coating process is complicated. Therefore, there is no need to worry about the occurrence of color difference that has occurred in each part of the decorative material, and both production and quality aspects can be improved.

(Example) Two-component polyurethane resin paint 4g / measure ^{2 on} natural wood veneer 1a
Is coated with a roll coater.

At this time, use a polyurethane paint with an elongation of 50%.

The obtained painted natural wood veneer 1 for front surface makeup is lapped and attached to the surface of a work material 3 having a wood fiber board as a base material as a base material by using a vacuum press.

In this way, color difference does not occur on the front and back, both sides, the stage,
It was possible to manufacture a decorative material that does not suffer damage to the coating film such as cracks and cracks even in the bent portion, with a simple process and without loss of paint.

(Effect of the invention) Since the pre-painted surface makeup veneer is attached to the surface of the object to be coated, compared to the conventional method in which the unpainted surface veneer is pasted onto the object to be coated and then spray painting is performed. No color difference occurs on the uneven surface.

Within the range of 3-500μ film thickness, 5% or more, preferably 7
Since a paint forming a coating film having a coating film elongation of up to 250% is selected and applied to the surface decorative veneer, the coating film is not cracked in the uneven portion of the surface of the object to be coated. That is, it becomes possible to maintain the coating film by selecting the thickness and elongation of the coating film.

Since the veneer for surface makeup can be painted using a roll coater, curtain coater, etc., it is possible to paint like the spray painting that was done after pasting the unpainted veneer for surface makeup on the decorative material as in the past. It can be painted without any loss.
