Abstract

PURPOSE:To obtain decorative sheet giving the impression as if natural wood is employed by a method wherein decorative paper with woodgrain pattern printed is pasted onto the surface of plywood or the like and polyester resin coating film, on the surface of which grooves are formed, is applied on the decorative paper so as to apply deep colored and lowly-glazed paint on the inner wall of each groove and the paint, which has the color lighter than that of the paint applied on the inner wall of the groove and is highly-glazed than the above-mentioned paint, on the surface plane part of the film. CONSTITUTION:On the plane base material A such as plywood or the like, decorative paper B with woodgrain pattern printed is pasted. Next, under the condition that the proper amount of fluid polyester resin is dropped on the paper and then the paper is covered with film having projecting parts corresponding to the vessel-like grooves to be formed on the decorative paper, the polyester resin is evenly spread over the base material A by applying an elastic roll from above the film so as to from polyester resin coating film C. Then, deep colored and matte primer D is applied to the surface of the coating film C and in the inner wall of each groove. Before the hardening of the primer D, the primer D except that in the inner wall of the groove is wiped off and hardened. After that, light colored and glossy finishing paint E is applied on the plane part of the film.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative board used for building interior materials, furniture, housing equipment and the like.

[0002]

2. Description of the Related Art A decorative board made of plywood or the like as a base material, with a decorative paper printed with a grain pattern on its surface
It is used in large quantities in building interior materials, furniture, housing equipment, etc. Some of these decorative boards are simply painted on a decorative paper with a wood grain pattern printed on them, and in order to bring them closer to natural wood, they have fine needle-shaped recesses similar to the conduit grooves of natural wood. In some cases, a decorative paper with grooves embossed is used, or the coating film for undercoating is embossed with the grooves and then subjected to final finish coating.

[0003]

However, when the decorative paper printed as described above is used and a groove similar to the conduit groove is artificially embossed, the reason is as follows.
The product value is inferior to that of natural wood.

When natural wood is coated, the inner wall of the conduit groove has a material difference from the surface portion other than the conduit groove (hereinafter, the surface portion other than the conduit groove is referred to as a flat surface portion), and therefore, compared with the flat surface portion. A large amount of paint is sucked in. Therefore, when painting, even if the difference in material between the flat surface and the inner wall of the conduit groove is not taken into consideration, the inner wall of the conduit groove is better than that of the flat surface as long as the paint penetrates into the conduit groove. It is painted thick and has a low gloss, and emphasizes the existence of conduit grooves, which is a characteristic of wood.

However, in the conduit groove artificially made as in the above-mentioned prior art, there is no difference in material between the inner wall of the conduit groove and the flat portion unlike natural wood. Nevertheless, in the prior art, the present situation is that the inner wall of the conduit groove and the flat portion are similarly painted. Therefore, unlike natural wood, since the conduit groove is not emphasized, it is inferior in aesthetics, and can be easily distinguished from natural wood, so that the commercial value is low. In addition, when natural wood is coated, since the conduit groove absorbs more paint than the flat surface portion, it is less glossy than the flat surface portion, so that the conduit groove does not appear to shine depending on the viewing direction. In the above-mentioned conventional decorative plate, since it has the same luster as the flat portion, the concave groove looks bright depending on the viewing direction, and at first glance it can be seen that it is an artificial product.

[0006]

DISCLOSURE OF THE INVENTION The present invention is an invention relating to a decorative plate in which the embossed groove is coated so that it looks like a conduit groove of natural wood. The details will be described below with reference to the drawings.

First, a decorative paper (B) having a grain pattern printed thereon is attached to a flat base material (A) such as plywood. Next, an appropriate amount of a fluid polyester resin is dripped almost at the center of the decorative paper,
On top of that, cover with a film that has convex parts corresponding to the conduit-shaped concave grooves to be formed on the decorative plate, and stretch the polyester resin evenly over the entire base material with elastic rolls on it, and evenly on the decorative paper A polyester resin coating film (C) having a uniform thickness is formed.

When the film is peeled off after curing the polyester resin, the convex portions of the film are transferred as concave grooves onto the polyester resin coating film (C) on the surface of the decorative plate. Next, if necessary, a polyurethane resin coating is mainly applied on the polyester resin coating film (C) to obtain a final finish. The steps up to this point are known techniques.

In the present invention, instead of the final finish coating of the decorative plywood, first of all, a conventional method such as an elastic sponge roll is used to coat the polyester resin coating film with the coating material (D) as the undercoat on the surface and the concave groove. Apply to the inner wall (see Figure 1). Before the paint is cured, the undercoat paint (D) applied to the portion other than the concave groove is wiped off with a wiping roll or the like. After the undercoat paint (D) is cured, the paint (E) is applied as a final coating. When coating the finish paint (E), a relatively hard coating roll may be used, and the coating amount may be adjusted to a small amount so that only the flat portion excluding the concave groove as shown in FIG. 2 is coated. It is essential.

By using a deeply colored matte paint as the undercoat paint (D) and a lightly colored luster paint as the finish paint (E), it is possible to paint as if it were applied to natural wood.
The groove is painted darker than the flat surface and has less gloss. In the above description, the glossy paint means a paint that is relatively glossy as compared with the undercoat matte paint (D), and does not necessarily have to be a full gloss paint. Similarly, the matte coating refers to a coating having a relatively less gloss than the gloss coating (E) for finish coating.

The relationship between the glossy paint and the matte paint is the same in the relationship between deep coloring and light coloring. That is, the lightly colored paint (E) for finish coating needs to be relatively thin as compared with the deeply colored paint for undercoating. , Transparent paint may be used.

Before the finish coating, the surface of the decorative plate may be ground with a sander to completely remove the undercoat paint (D) remaining on the flat surface. Finish paint is undercoat paint (D)
Since it is not affected by, the concave groove is further emphasized and the entire decorative plate can be finished evenly.

[0013]

EFFECT OF THE INVENTION There is a relative shade difference and a relative gloss difference between the undercoat paint (D) applied in the recess and the finish paint (E) applied on the flat surface portion, Due to the difference in shade and the difference in gloss, the conduit-shaped concave groove artificially formed on the decorative plate is emphasized, and a deep appearance is exhibited. Also, since the gloss of the concave groove is less glossy than the flat part, unlike the decorative board of the prior art, there is no unnatural phenomenon that the conduit groove looks bright, which is not seen in natural wood, as if it were It looks like a veneer made from natural wood.
