[Industrial applications]

 The present invention relates to a structure of a decorative panel used for interior partitions, doors, counter tops, desk tops, furniture members and the like.

[0002]

[Prior art]

 Conventionally, as a decorative panel used for interior partitions, doors, desk top plates, etc., a solid core structure decorative panel with a core material made of plywood, particle board, medium fiberboard, etc. A so-called loose flash in which a frame and crosspieces are assembled with a wooden material, a space is filled with a paper core to form a core material, and a decorative plate is used as a front plate on at least one surface, and the front plate is attached to both surfaces of the core material. There was a makeup panel for the structure.

[0003]

[Problems to be solved by the device]

 The decorative panel with a solid core structure has excellent sound insulation and shock resistance, and has little deflection with respect to the load. It is attached to any part of the panel, such as processing for joining and fixing with other members, fittings, parts, etc. Although it has the advantage that it can be used, the weight is increased, and it is more expensive in price than the decorative panel with a flash structure.

When a particle board or a medium-quality fiberboard is used as the core material, the material is not dense as compared with the wood itself, so that the screw holding power is lower than the wood, and depending on the application, the strength is low. There were cases where it was insufficient.

[0005] In the case of a flash structure decorative panel, it is possible to reduce the weight, but when connecting it to other parts with screws or attaching metal fittings, it can be installed only at the position of the crosspiece of the core material. First, the crosspieces had to be arranged at the mounting position in advance, and it was not possible to change the mounting position after the cosmetic panel was manufactured.

Further, it is necessary to use a material having sufficient strength for the crosspiece, and a piece made of wood, plywood, laminated wood or the like has been used.

The present invention achieves weight reduction and material saving, allows members to be connected to desired desired locations, and can be attached with metal fittings, and has the strength required for easy mounting. The purpose is to obtain a cosmetic panel with excellent productivity and economy.

[Means for Solving the Problems]

 The present invention is a decorative panel in which a paper core is used as a core material, and a front plate having a thickness of 1.0 to 6.0 mm is attached to both surfaces thereof, and the front plate on at least one side is a decorative plate. A hole having a desired depth that penetrates the plate and reaches the core material is formed, and a piece of wood that fits into this hole is bonded to the core material and the back surface of the perforated front plate with an adhesive. This is a makeup panel.

The core material of the decorative panel of the present invention includes a honeycomb core, a roll core, which has the same thickness as the frame material, in a space surrounded by the frame material made of wood, plywood, laminated wood or the like. A material filled with a paper core material such as a feather core or a corrugated cardboard laminate is used, and a front plate having a thickness of 1.0 to 3.0 mm is attached to both surfaces thereof with an adhesive.

The core material can be reinforced by incorporating a crosspiece member if necessary. A decorative plate is used on at least one surface side of the front plate to be bonded to the surface of the core material, and a plate material such as plywood or medium fiber board is usually used on the other surface. Decorative boards are used on both sides if a beautiful design is required on both sides. Examples of the decorative board used in the present invention include, but are not limited to, a melamine decorative board, a polyester decorative board, a vinyl chloride decorative board, and a diallyl phthalate decorative board.

A suitable thickness of the front plate is 1.0 to 6.0 mm, and when the thickness is 1.0 mm or less, it is not sufficient in impact strength and appearance when laminated with the core material, and it fits into the hole. It is difficult to maintain sufficient strength when fixing tied pieces of wood. If the thickness is more than 1.6 mm, it is not advantageous in terms of economy.

As the adhesive used for bonding the core material and the front plate, a urea resin-based adhesive, a melamine resin-based adhesive, a vinyl acetate resin-based adhesive or the like is appropriately used depending on the application.

After the bonding between the core material and the face plate is completed, a hole is formed at the position where the member is joined and the metal fitting part is attached, which penetrates the face plate and reaches the paper core. The diameter and depth of the holes can be determined as needed.

After the holes are opened, an adhesive is injected and filled into the perforated holes, and a cylindrical wood piece that is close to the shape of the perforated holes and can be fitted is inserted and fitted to form a core material. It is bonded to the paper core and the back of the front plate.

As the adhesive, various adhesives used for bonding the core material and the front plate can be appropriately selected, but a foaming adhesive having a foaming ratio of 1.5 to 2.0 times. It is preferable to use since it is possible to harden the front plate and the back surface in a brim shape and firmly bond them.

It is necessary to use a material having a sufficient strength such as a screw holding force for the wood piece inserted into the hole. The inserted piece of wood is adhered to the core material via an adhesive, and the filled adhesive is fixed and adhered to the back surface of the front plate in a brim shape.

In the decorative panel thus obtained, it is possible to join a member to a piece of wood inserted into a hole and to attach a metal fitting or the like. Hereinafter, description will be made based on examples.

【Example】

 Example 1 A space 2 surrounded by a frame material 1 made of wood having a thickness of 25 mm was filled with a corrugated cardboard-shaped panel paper core having the same thickness as the frame material 1 to form a core material 2. As a front plate 3, a 1.2 mm thick melamine decorative plate and a 1.2 mm thick phenol resin laminated plate are attached to each other using a vinyl acetate resin emulsion adhesive, and the core material 2 and the front plate are attached. After the completion of the bonding of No. 3, the outer edge of the frame material 1 was cut so as to become the edge material of the decorative panel 6, and polishing and painting were performed.

Next, a hole having a diameter of 20 mm and a depth of 15 mm is opened at the table leg attachment position of the phenol resin laminated plate, and a polyurethane adhesive (having a foaming ratio of 1.8 times as the adhesive 5 is provided in the hole portion). Aika Aibon WX-573) manufactured by Aika Kogyo Co., Ltd. was injected, and a cylindrical wood piece 4 made of beech wood with a diameter of 19.5 mm and a length of 10 mm was inserted and fitted, and then the adhesive was hardened to remove the wood piece. A decorative panel 6 for a dining table top plate was obtained by bonding 4 to the core material 2 and the back surface of the front plate 3.

Since the wood piece 4 is arranged at the table leg attachment position of the front plate 3 on the rear surface side of the decorative panel 6, the table leg frame which is the joining member 7 can be easily attached by using screw nails. It was

Comparative Example 1 As Comparative Example 1, a 150-type (U-type) particle board having a thickness of 25 mm and defined by JIS A5908 was used as a core material, and a thickness of 1. A 2 mm melamine decorative board and a phenol resin laminated board were laminated using a vinyl acetate resin emulsion adhesive to obtain a decorative panel.

Comparative Example 2 As Comparative Example 2, a medium-quality fiberboard (MDF) having a thickness of 25 mm was used as a core material, and a front panel was laminated in the same manner as in Comparative Example 1 to obtain a decorative panel. A wood screw holding force test was conducted on Example 1, Comparative Example 1, and Comparative Example 2. The test results are shown in Table 1.

Test method: A square test piece of 50 mm × 50 mm centering on the mounting portion of the wood piece 4 of the decorative panel manufactured under the same conditions as in Example 1 is cut out and used as a test piece. For Comparative Example 1 and Comparative Example 2, test pieces having the same size and shape are prepared from an arbitrary portion of the decorative panel.

Next, a wood screw with a cross hole having a diameter of 2.7 mm and a length of 16 mm specified in JIS B112 was provided with a screw portion (about 11 mm) perpendicular to the center of the surface of the test piece on which the phenol resin laminated plate was attached. After screwing in, fix the test piece and pull out speed about 2. The wood screw is pulled out vertically at 0 mm / min, the maximum load is measured, and the average value is obtained. This test was carried out on each of three test pieces, and the average value was used as the wood screw holding force.

[Effect of device]

 Since solid wood such as plywood is not used as the core material of the decorative panel, the material can be saved and the weight can be reduced, and handling and transportation are easy. The decorative panel of the present invention is perforated at a desired position, and a piece of wood that serves as a base for fixing parts and the like is fitted and fixed in place. It is not necessary to have a structure in which crosspieces are placed at the attachment points of fittings, fittings, parts, etc.

Also, the wood pieces to be fitted and fixed may be smaller than the crosspieces, the usage amount is small, and the wood pieces are installed only at the joining portion. Therefore, even if a high quality one is selected from the viewpoint of strength retention, the price is low. Has a small effect on the product quality and is easy to maintain quality. Therefore, it is possible to omit the crosspiece.

In the decorative panel of the present invention, at the perforated part, the end of the cut paper core is wrapped with the adhesive so as to be adhered to the inserted wood piece, and further, to the back surface of the front plate, Since the adhesive solidifies and adheres in a brim shape in an area larger than the diameter of the hole, it does not break due to external force such as pulling load, and the strength of the inserted wood piece itself can be fully exerted. You can

The decorative panel of the present invention is generally attached to the member, part, etc. at many places such as the back surface which are invisible to the human eye, and the wood piece fitted and embedded may be small. It is hidden by and can be finished practically without any discomfort.
