Abstract

PURPOSE:To enhance the aesthetic appearance by applying a decorative panel to a framework member or a core member so as to leave parts in the vicinity of a side face along a one direction, as undecorative parts, by forming straight line-like grooves in the framework member or core member along the boundary between the decorative plate and the framework member or core member so as to form the undecorative parts in a desired shape, and by continuously applying a decorative sheet different from the decorative plate, onto the undecorative parts of the framework member or core member including the grooves. CONSTITUTION:Cut parts are formed opposite corner parts of a peripheral of a framework member 1 in the form of an aggregate. Decorative plates 4 which are obtained by thermally press-bonding a resin impregnated decorative sheet 3 having a straight-grained pattern onto the outer surface of an MDF 2 are integrally incorporated with the cut parts in the opposite corner parts through the intermediary of a vinyl chloride resin adhesive so as to form a panel base board 5. Thin grooves 6 are formed on the outer surface of the panel base board 5, in parallel with the side faces thereof, along the boundaries between the core member 1 and the decorative plates 4. Then, chamfered parts are formed in the end parts of the panel base plate 5, and after a vinyl chloride resin sheet 8 is filled in the thin grooves 6 in the panel board 5 having the side faces which are coated with an acrylic resin group adhesive including the thin grooves 6, the sheet 8 is then applied continuously over an undecorative part in its entirety. Further, cut-face decorative sheets 9 having a color pattern the same as that of the sheet 8 are applied by an edge bonder.

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

[0002]

2. Description of the Related Art Conventionally, as one of the inexpensive decorative panels used for furniture, building materials, etc., a concave portion or a curved surface portion having a desired shape is formed in the vicinity of a side surface portion of a board such as plywood, particle board, LVL and MDF. There was a decorative panel manufactured by cutting and forming, and then vacuum-bonding a decorative sheet such as a vinyl chloride resin sheet from the front surface to the side surface and further to the back surface and continuously adhering it along the shape of the substrate. .

[0003]

However, in the above decorative panel, in order to cover the whole with a single decorative sheet, a concave portion or a curved surface portion having a desired shape is cut and formed in the vicinity of the side surface portion. The pattern was monotonous and poor in design. In particular, when using a decorative sheet with a wood pattern, 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 it only has a three-dimensional effect. However, since the decorative sheets were the same, the innocence could not be expressed at all.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is constructed by attaching decorative plates to both sides of a frame material or core plate material, and applying a make-up decoration to the side surfaces. In the method for manufacturing a decorative panel, after affixing the decorative plate so that the vicinity of the side surface portion along one direction of the frame material or the core plate material is left as an uncoated part, a straight line is formed at the boundary between the decorative plate and the frame material or the core plate material. -Shaped decorative groove in which a groove and a non-decorated part are cut and formed into desired shapes respectively, and then a decorative sheet separate from the decorative plate is continuously attached to the undecorated part including the groove of the frame member or the core plate material. The present invention has been solved by providing a manufacturing method of.

[0005]

In the present invention, after the decorative plate is attached so that the vicinity of the side surface along one direction of the frame material or the core plate material is left as an undecorated portion, a straight line is formed at the boundary between the decorative plate and the frame material or the core plate material. Each of the groove and the unpainted part is cut and formed into a desired shape, and then a decorative sheet separate from the decorative plate is continuously attached to the unpainted part including the groove of the frame material or the core plate material. This is because by using the groove as a boundary, the materials and patterns on both sides of the groove are made different to give the appearance of a high-class panel in which frames of different materials are combined.

The present invention will be described below in detail with reference to the drawings of the embodiments.

As the core material 1 used for the frame material or core plate material of the present invention, plywood, particle board, wafer board, MDF, LVL, LVB, OSB and the like are used alone or in combination, or laminated materials. Generally, wood-based materials such as gypsum board, gypsum cement board, gypsum slag board,
Any material that can be cut such as an inorganic material such as a pulp cement board, an asbestos cement board, a lightweight cellular concrete, or a synthetic resin material may be used.

The decorative plate 4 is a plywood or MD having a relatively thin thickness.
Using F as the substrate 2, the decorative layer 3 formed on the surface is
After impregnating a synthetic resin such as melamine resin or diallyl phthalate resin on thin paper or titanium paper on which a desired color pattern is printed and formed, heat and pressure cure it while making the desired unevenness on the surface, and stain the recesses with stain etc. Resin impregnated sheet,
A decorative sheet with a 0.2 mm thick veneer backed with Japanese paper, a vinyl acetate resin, EVA resin, acrylic resin emulsion type, or thermosetting urea resin or melamine resin. The decorative plate 4 can be adhered to the substrate 2 through a common adhesive mixed in a mold, or by directly applying an enamel paint made of urethane resin, amino resin, acrylic resin or the like on the upper surface of the substrate 2. Make up.

Then, a frame member or core plate material is formed using the core material 1. If the frame member has a flash structure as shown in FIG. 1, the frame member is formed by forming the frame with the core member 1 cut into a rod shape, and if the core plate member has a solid core structure as shown in FIG.
The plate-shaped core material 1 is used as it is to form a core plate material. Then, as shown in FIG. 2, the decorative board 4 is adhered on both surfaces so that the vicinity of the side surface along one direction is left as an unpainted portion, and the panel substrate 5 is configured. At this time, the undecorated portion near the side surface portion may have substantially the same height as that of the decorative plate 4 attached as shown in FIG. 2, or may have a different height. As the adhesive, a usual adhesive for wood such as urea resin or vinyl acetate resin is used, and they are bonded and integrated by a pressing device such as a cold press.

Next, the vicinity of the side surface of the panel substrate 5 and the boundary between the decorative plate 4 and the frame member 1 or the core plate member are cut by a cutting machine such as a router or a saw as shown in FIG. The boundary between the decorative plate 4 and the frame member 1 or the core plate member is a linear groove 6 extending along one direction of the panel substrate 5, and the side surface portion is rounded to form a chamfered portion 7 having a desired shape. A part that looks like a so-called frame is formed by attaching different materials to the side surface of the substrate 5.

Then, as shown in FIG. 4, a decorative sheet 8 which is a separate body from the decorative layer 3 is continuously attached to the undecorated portion near the side surface of the cut panel substrate 5 for makeup. The separate decorative sheet 8 is a decorative sheet having a color pattern different from that of the decorative layer 3, or a decorative sheet made of a different material. For example, when a solid material is desired to be expressed, if the decorative layer 3 is a straight pattern, the decorative sheet 8 Is used, or in order to reduce the cost, resin-impregnated paper is used for the decorative layer 3 and a vinyl chloride resin sheet is used for the decorative sheet 8. Then, it is attached using an edge material attaching machine such as an edge bander.
When attaching the decorative sheet 8, the width of the decorative sheet 8 is made a little wider than the width of the attached portion in advance, and when the trimming is performed after the attachment, the joint between the decorative layer 3 and the decorative sheet 8 becomes inconspicuous. preferable.

Further, when the groove 6 formed between the decorative plate 4 and the unpainted portion is a fine groove having a width of 3 mm or less as shown in FIG. 3, the end of the decorative sheet 8 is formed by the fine groove 6 described above. After burying it in, make sure to attach it to the entire side surface.

Then, finally, a decorative sheet 9 as shown in FIG. 9 is attached to the side surface of the other side of the decorative panel to obtain a decorative panel as shown in FIG. 9, which is used as a door for a cabinet or the like.

【Example】

(Example 1) A laminated member assembled to a thickness of 30 mm was formed into a frame member 1
Then, cutting portions having a depth of 5 mm were formed at both corners of the peripheral frame material. Then, a decorative plate 4 having a grain-patterned resin-impregnated decorative sheet 3 impregnated with a diallyl phthalate resin on the surface of the MDF 2 having a thickness of 5 mm is thermocompression-bonded, and a vinyl acetate resin adhesive is applied to both corners of the cutting part. It was bonded and integrated with a cold press via the above to form a panel substrate 5 having a flash structure (FIGS. 1 and 2).

Next, a linear fine groove 6 having a depth of 5 mm and a width of 2 mm is formed by cutting parallel to the side surface portion at the position of the boundary between the core material 1 and the decorative plate 4 on the surface of the panel substrate 5. The edge of the panel substrate 5 is chamfered 7, and an acrylic resin adhesive is applied to the entire side surface of the panel substrate 5 including the narrow grooves 6, and the wood grain pattern of the board is made uneven to be colored with stain. A vinyl chloride resin sheet 8 having a thickness of 0.2 mm was embedded in the fine groove 6 and then continuously attached to the entire unpainted portion using an edge bander (FIGS. 3 and 4).

Finally, a wood-mouth decorative sheet 9 having the same color pattern as that of the vinyl chloride resin sheet 8 is attached to the side surface of the other side with an edge bander to clarify the pattern and material of the side surface and the flat surface. A decorative panel having a high-grade appearance, which appears differently and is formed by cutting a solid material and forming it on the side of the decorative panel, was obtained.

Example 2 A core plate 1 made of particle board having a thickness of 25 mm has a thickness of 7 mm and a width of 30 on both sides.
mm decorative sheet material 1'made of MDF and a decorative board 4 having a decorative coating film 3 formed by applying an ivory-colored urethane resin-based enamel coating on the surface of a plywood 2 having a thickness of 7 mm are contacted and integrated, A panel substrate 5 having a solid core structure was used (FIGS. 5 and 6).

Next, between the contact portion between the undecorated board material 1'of the panel substrate 5 and the decorative board 4, a router has a depth of 8 mm and a width of 5 m.
A straight, gentle U-shaped groove 6 of m was cut and formed in parallel with the side surface portion, and the side surface portion of the panel substrate 5 was chamfered 7. Then, a vinyl acetate adhesive is applied to the entire side surface portion including the groove 6 of the panel substrate 5, and a 0.2 mm thick diallyl phthalate resin-impregnated cured decorative sheet 8 formed by using gray colored paper is edged. It was continuously attached with a bander (Figs. 7 and 8).

Finally, on the other side surface part, a wood edge decorative sheet 9 composed of a gray diallyl phthalate resin-impregnated hardened paper decorative sheet is attached by an edge bander, and it is as if a decorative frame material made of another material is fixed on the side surface part. A decorative panel with a modern, visible appearance was obtained (Fig. 9).

[0020]

According to the decorative panel of the present invention, the handle and material of the decorative layer in the vicinity of the side surface portion and the flat surface portion are different from those of the conventional one-piece decorative sheet or a decorative panel produced by one-color coating. Since it is different at the step, it looks like a combination of different materials on the side, and it is possible to obtain a decorative panel that can be manufactured at low cost, has a high degree of processing, has an extremely high-quality appearance, and has a high-quality appearance. .
