DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative panel used for furniture, building materials and the like, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, as one of inexpensive decorative panels used for furniture, building materials and the like, a concave portion or a curved surface portion having a desired shape is provided in the vicinity of a side surface of a substrate such as plywood, particle board, LVL, and MDF. There has been a decorative panel manufactured by a method in which a decorative sheet such as a vinyl chloride sheet is vacuum-compressed or continuously adhered along the shape of a substrate from the front surface to the side surface and further to the rear surface after cutting.

[0003]

However, in the above decorative panel, since the whole is covered with one decorative sheet, even if a concave portion or a curved surface portion having a desired shape is cut and formed in the vicinity of the side portion, the pattern is formed. Was monotonous and poor in design. In particular, when using a wood-grained decorative sheet, some decorative panels were cut and formed with steps or recesses to make it look like a frame was attached near the side of the decorative panel, but only with a three-dimensional effect. However, since the decorative sheets were the same, pure feeling could not be expressed at all.

Hereinafter, the present invention will be described in detail with reference to the drawings of embodiments.

As the substrate 1 used in the present invention, plywood,
Particle board, wafer board, MDF, LV
L, LVB, OSB, etc. are used alone or in combination, and wood-based materials such as laminated wood are generally used. However, gypsum board, gypsum cement board, gypsum slag board, pulp cement board, asbestos cement board, Any material that can be cut such as an inorganic material such as lightweight cellular concrete or a synthetic resin material may be used.

[0007] A decorative layer 2 formed on the front and back surfaces of the substrate 1
As the thin paper on which the desired color pattern was printed and formed, a titanium paper was impregnated with a synthetic resin such as a melamine resin or a diallyl phthalate resin. Resin-impregnated sheets, decorative sheets with Japanese paper lined on the back of veneer with a thickness of about 0.2 mm, vinyl acetate resin, EVA
Or an emulsion type such as an acrylic resin type or a thermosetting type such as a urea resin or a melamine resin, is adhered to the substrate 1 via a common adhesive, or urethane is directly applied to the upper surface of the substrate 1. Resin, amino resin,
Formed by applying a paint ing an acrylic resin or the like, constituting the panel board 3.

[0008] A decorative layer 2 formed on the front and back surfaces of the substrate 1
As a thin paper having a desired color pattern printed thereon, a titanium paper is impregnated with a synthetic resin such as a melamine resin or a diallyl phthalate resin, and then subjected to heat-pressure curing while applying a desired emboss to the surface, and a resin subjected to a colored wiping treatment. An impregnated sheet, a decorative sheet of Japanese paper backed on the back of a veneer with a thickness of about 0.2 mm, a vinyl acetate resin, EVA
Emulsion type such as acrylic resin or acrylic resin, or urethane resin, amino resin,
The panel substrate 3 is formed by applying a synthetic resin paint such as an acrylic resin.

Next, the vicinity of the side surface of the panel substrate 3 having the decorative layer 2 formed on one or both sides is cut into a desired shape by a cutting machine such as a router. The flat portion near the side portion is a step portion 4 formed of a linear groove or a concave portion. The side portion is cut into a chamfered portion 5 having a desired shape so as to be rounded, and a different material is attached to the side portion of the panel substrate 3. It forms a part that looks like a so-called frame. At this time, among the decorative layers 2 formed on the surface of the panel substrate 3, the cutting process is performed so as to remove all the decorative layers 2 near the side portions bordering the step portion 4.

A decorative sheet 6 separate from the decorative layer 2 is continuously adhered to the vicinity of the side surface of the cut panel substrate 3 to make up. As the separate decorative sheet 6, a decorative sheet having a different color and pattern from the decorative layer 2 or a decorative sheet having a different material is adhered using an edge material attaching machine such as an edge bander.

When the decorative sheet 6 is attached, the width of the decorative sheet 6 is set to be slightly larger than the width of the attached portion in advance. Is inconspicuous and preferred.

Finally, a decorative panel as shown in FIG. 2 is obtained by sticking a decorative sheet 7 on the short side of the decorative panel, and is used as a door for a cabinet.

[0013]

According to the present invention, the decorative layer in the vicinity of the side surface of the panel substrate having the decorative layer formed on the surface is cut and removed into a desired shape with the step formed as a boundary, and is separated from the decorative layer on the flat portion. The continuous application of the decorative sheet to the cut-formed step portion and the curved surface portion is performed by using different patterns and materials on both sides of the cut-formed step portion as a boundary, thereby combining different materials. This is for giving an appearance like a panel.

[0014]

EXAMPLES (Example 1) A particle board cut into a rod having a thickness of 30 mm was used as a frame material, and both sides thereof were 5 m thick.
A decorative board in which a resin-impregnated decorative sheet obtained by embossing a grain-grained wood grain pattern on a titanium paper impregnated with diallyl phthalate resin on the surface of a plywood and being subjected to a colored wiping process is hot-press bonded, adhesive is applied to both sides of the frame material. To form a flash-structured panel substrate.

Next, on the front surface side of the panel substrate, a straight U-shaped groove having a depth of 4 mm is cut in parallel with the side surface at a position 60 mm from the side surface by a router to form a step portion. The edge of the decorative panel was chamfered so as to remove a part of the resin-impregnated sheet near the outer side surface and on the back surface from the portion.

Using an edge bander, an acrylic resin-based adhesive is applied to the entire area of the panel substrate near the side surface and the back surface where the decorative layer has been cut and removed, and embossing is applied to the woodgrain pattern. A 0.2 mm thick vinyl chloride resin sheet that had been subjected to a colored wiping process was continuously adhered.

Finally, a glue sheet made of a vinyl chloride resin sheet is adhered to the short side surface portion with an edge bander, and the pattern and material of the vicinity of the side portion and the flat portion clearly appear, as if they appeared. A decorative panel having a high-grade appearance was obtained as if a frame made by cutting solid wood was formed on the side of the decorative panel.

[0018] both sides of the substrate of MDF (Example 2) thickness 18 mm, and the ivory urethane resin paint to form a coating to the decorative coating panel substrate. Next, a straight U-shaped groove having a depth of 3 mm is cut in parallel with the side surface at a position 50 mm from the side surface of the router in parallel with the side surface, and a step is formed. A part was cut to form an inclined surface, and the decorative coating on that part was removed.

Then, a vinyl acetate resin-based adhesive is applied to the entire area of the rear surface of the panel substrate from which the decorative coating has been cut and removed by using an edge bander, and formed using gray colored paper. The 0.2 mm-thick diallyl phthalate resin impregnated and cured decorative sheet was continuously adhered.

Finally, a kiguchi decorative sheet made of a hardened paper decorative sheet impregnated with diallyl phthalate resin is adhered to the short side surface by an edge bander, and a modern decorative frame material made of a different material is fixed to the side surface. An apparent decorative panel was obtained.
