Description

[Detailed Description of the Invention] [Field of Application of the Invention] This invention relates to the configuration of a decorative sheet-applied decorative board with a good finish and excellent workability.

[Prior art and problems] Decorative laminates, in which a decorative sheet such as printed paper is pasted onto the top surface of a substrate such as plywood, are widely used because they are inexpensive and easy to install. It has shortcomings. Therefore, although it is more labor-intensive and expensive to install than decorative boards, there is still a strong demand for wallpaper in which the joints on the applied surface are not noticeable. Therefore, various configurations have been proposed in which the seams are less noticeable, such as applying wallpaper to decorative boards.To give an example, Utility Model Registration No. 1224127 is
An adhesive layer covered with release paper is provided around the periphery or both sides of the substrate, and an adhesive is also applied to the center of the substrate.
This decorative board has a structure in which a decorative sheet with an area larger than the substrate is adhered to the entire surface of the board, and the method for installing the decorative board is to first adhere the decorative board to a base material such as a rim, and then to The decorative sheets protruding from the periphery are overlapped on a release paper and cut, and then the release paper is peeled off and the cut surfaces of the decorative sheets are butted together on an adhesive layer and adhered to make the seam less noticeable.

By the way, when constructing a decorative board like the one above,
The most problematic point is that the release paper provided around or on both sides of the substrate is not easily peeled off and is torn along the way, significantly reducing workability. The cause is
When applying adhesive to the center of the substrate, the adhesive is applied not only to the substrate but also to the surface of the release paper provided around or on both sides of the substrate, forming a continuous adhesive film. There is a particular thing. In particular, the release paper that covers the top surface of the adhesive layer has a release agent such as silicone resin applied to its front and back surfaces so that it can be easily peeled off. Since the surface is not subjected to any treatment, the adhesive may adhere to the side surface of the release paper or be drawn under the decorative sheet.

[Purpose of the invention] This invention was made to solve the above-mentioned problems, and its purpose is to provide a decorative sheet-attached decorative board whose release paper is easy to peel off.

[Structure of the device] In order to achieve the above object, in this device, an adhesive layer is provided at the edge and center of the substrate surface with a gap between the edges, and the adhesive layer provided at the edge of the substrate surface is The present invention relates to a decorative sheet-attached decorative board in which a decorative sheet having a larger area than the surface of the substrate is adhered to the entire surface so as to be covered with release paper.

Hereinafter, this invention will be explained in detail with reference to drawings serving as examples.

FIG. 1 shows a sectional view of a decorative board as an embodiment of this invention, and FIG. 2 is an enlarged sectional view showing an embodiment for providing a gap between adhesive layers.

The substrate 1 is a commonly used wood board such as plywood or particle board, asbestos board, calcium silicate board,
Inorganic board materials such as gypsum board are used.

Reference numeral 2 denotes an adhesive layer formed on the edge of the substrate 1, the upper surface of which is covered with a release paper 3. The adhesive layer 2 is preferably a sheet of nonwoven fabric or thin paper with a thickness of about 5 to 7 microns, coated and impregnated with a rubber-based or acrylic resin-based adhesive on both sides. In addition, the width of adhesive layer 2 is 10 to 40
About mm is appropriate.

The release paper 3 is made of high-quality paper having a thickness of about 10 to 15 μm and coated with a release agent such as silicone resin or wax on both sides. Reference numeral 4 denotes an adhesive layer formed at the center of the substrate 1, and is provided by applying an adhesive to the entire surface of the substrate 1 except where the adhesive layer 2 is formed.

However, the adhesive layer 2 and the adhesive layer 4 are not brought into close contact with each other, but a gap 6 is provided between them. The width of the gap 6 is in the range of about 0.5 to 3 mm.

In this invention, the gap 6 is provided at the boundary between the adhesive layer 2 and the adhesive layer 4. The reason why the gap 6 is provided at the boundary between the adhesive layer 2 and the adhesive layer 4 is to roll up the decorative sheet 5 adhered with the adhesive layer 4 and use the release paper 3 that covers the upper surface of the adhesive layer 2. This is to allow the release paper 3 to be peeled off very easily without the side edges of the release paper 3 getting caught on the adhesive layer 4 or the decorative sheet 5. As for the type of adhesive for forming the adhesive layer 4, commonly used adhesives for pasting decorative sheets, such as vinyl acetate emulsion type adhesives, acrylic resin adhesives, and starch adhesives, are used. As shown in FIG. 2, the method for forming it is that after pasting a double-sided adhesive tape integrally covered with adhesive layer 2 with release paper 3 to the required edge of substrate 1, the above-mentioned adhesive tape is applied from the top surface. Paper tape that is about 2 mm wider than the release paper 3 or tape 7 coated with adhesive is pasted on top of the substrate 1 so that it protrudes inside the substrate 1, and then the substrate 1 is
It is preferable to apply the coating to the entire surface using a coating device such as a spreader or a spray coater, and then peel off the tape 7.

Reference numeral 5 denotes a decorative sheet pasted on the substrate 1, which is larger in area than the substrate 1 and is pasted over the entire surface of the substrate 1. As the decorative sheet 5, wallpaper made of paper, cloth, synthetic resin film, etc. is used.

[Effects of the invention] As mentioned above, the decorative board of this invention has a gap at the boundary between the adhesive layer covered with release paper and the adhesive layer to which the decorative sheet is attached, so the release paper is Because it can be easily removed without adhering to the side surfaces or being pulled under the decorative sheet, it has the effect of making the installation of decorative sheets easier than with conventional decorative sheets. .
