Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a decorative board in which a decorative paper coated with a decorative pattern such as wood grain printed on thin paper is provided on the front and back sides of a plate-like base material such as particle board or medium-specific gravity fiberboard. The present invention relates to a decorative method for decorating the edges of a decorative board, in which both ends are cut into a desired shape and the edges are decorated using decorative paper with a thin base layer left behind.

0002

[Prior Art] Wood is often used as a base material in conventional decorative laminates, but there has been a change from decorative laminates with flash processed base materials made by partially pasting wooden members to decorative laminates with solid core materials. It's coming. This is based on the demand for higher quality decorative boards and diversification of sizes, and a typical example is quick step processing (a process in which chip material of particle board or medium-specific gravity fiberboard is hardened by heat pressing using a urea resin adhesive to create a decorative board. There is a decorative board made by (manufacturing boards). This decorative board always requires decoration on both ends of the decorative board depending on the purpose of use.For example, it is common to perform decoration on the ends using a separate member or part, such as edge band processing or lamination of molding material. be. However, it is difficult to obtain a decorative board with a sense of unity using decorative paper on both sides.

On the other hand, although it is one-sided, relatively thick decorative paper such as vinyl chloride resin is used, cut to leave a thin layer of the base material on the back side of the decorative paper, and then glued to the edge of the decorative board. There is a makeup method in which the paper is folded and pasted to cover it or it is rolled up to both sides, or a makeup method in which a single-sided decorative paper is made longer than the base material and pasted on the edge of the base material or rolled up to the end of the back side. Publication No. 49-30454, Japanese Patent Application Publication No. 59-114
015 Publication) and has been implemented. However, the above-mentioned decorative method uses decorative paper on only one side, and when relatively thick decorative paper is used, it is difficult to provide a decorative board that meets the demand for high-quality decorative paper that has an almost endless sense of unity with the decorative paper on both sides. is difficult.

0004

[Problems to be Solved by the Invention] As described in the prior art, in a makeup method that leaves a thin layer of base material at a constant thickness on the back side of decorative paper, the decorative paper with a thin layer of base material is folded at a steep angle. Bending tends to cause the thin base layer to break, and the cut shape of the edges makes manufacturing difficult. In addition, by this method, decorative paper is pasted on both sides, and a gap is created at the joint between the two decorative papers by the thickness of the thin layer of the remaining base material, making it difficult to obtain a nearly endless sense of unity. On the other hand, if the decorative paper is made longer than the base material and decorated to cover the edges, there will be problems with adhesion at the rough chip part like the particle board used as the base material, and unevenness will occur on the decorated edge surface. It is difficult to meet the demands for a decorative board that is easy to clean and has a high-class feel. SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a method for decorating the ends of a decorative board in which both ends of the decorative board are provided with a new decoration.

[0005]

[Means for Solving the Problems] The present invention has been made in view of the conventional problems, and when the plate-like base material according to the present invention is a particle board subjected to quick step processing, and in the decorative paper, vinyl chloride is used. Both ends of the decorative board, which is made by laminating decorative paper made of tissue paper (decorative paper made of thin paper overcoated with urethane resin or amino resin) that cannot be rolled up like decorative materials, are attached to the back side of the front surface. A thin layer of base material remains on the side of the end of the decorative paper on the back.The base material is cut with an incline with a different thickness so that it becomes thinner toward the edges, and then pasted with adhesive to cover the base material. It is characterized by joining the end surfaces of the surface decorative paper.

[0006] The core material of the plate-like base material used in the present invention is particle board, and this particle board is usually made of rough chips as a core and fine chips bonded to both sides with heat and pressure using a urea adhesive. The edges of the decorative board with the decorative paper pasted are cut using a cutting blade that can obtain the desired shape, and the thickness is sloped so that the closer it gets to the side of the edge, the thinner it is. The decorative paper is cut to leave a gentle slope, the back side of the decorative paper is pasted to the base material, and the edges of the front decorative paper and the back decorative paper are closely bonded to create a decorative board with a sense of continuity and unity. Obtainable.

[0007]

[Function] As mentioned above, when adhering decorative paper with a thin layer of base material to the base material, a small cavity is created at the deepest part of the cut, but the base material has a hilly shape with a gentle slope. The thin layer of chemical paper with a slight angular difference in thickness creates a strong adhesion that is not affected by external pressure or impact, and also prevents unevenness on the adhesion surface. Due to this action, flexible edge processing, that is, joining of front and back decorative papers can be easily performed.

[0008]

[Embodiments] Examples will be described in detail below with reference to the drawings. FIG. 1 is a cross-sectional view of a decorative board obtained by cutting the end base material of the decorative board. The surface layer (9) made of fine chips of the particle board (4), which is the base material, is cut at an angle so that a thin base layer (3) remains on the back side of the decorative paper (1), and the edges of the base material ( 2), (2
), a hill-like base material portion (11) having a gently sloped semicylindrical shape is formed. At this time, the thickness of the thin base layer on the back side of the decorative paper is 1.0 to 1.5 m at the deepest part (A) including the decorative paper.
At the m end (B), a thin base layer with a thickness of 0.5 to 0.7 mm was obtained. However, a slope with a thickness difference of 1.0 mm to 0.5 mm is desirable. The tissue paper used in this case has a basis weight of 23 to 50 g.
/m2 paper was used.

[0009] Further, an adhesive was applied to the hill-shaped base material portion (11) and the adhesive was pressed from above along the base material portion with a roll, thereby completing a decorated end portion. Figure 2 shows the decorative board (1
0) is a sectional view showing the decorated end portion of FIG. In this case, the joint (5) between the front decorative paper (1) and the back decorative paper (1a)
The adhesion was such that a single fine line remained, resulting in an inconspicuous decorative board with a sense of unity.

FIG. 6 shows a cross-sectional view of a particle board currently being supplied for decorative laminates. The whole has a three-layer structure, consisting of a rough chip core material (8) and fine chips or fibers (9) and (9a), but in the present invention, this particle board base material (4) has this layer structure. It was used and the edges were treated. FIG. 3 shows a cutting blade for cutting and the cutting state. The cutting edge (7) of the cutting blade (6) is preferably cut off and has a width of 1 mm or more. Also cutting blade (6)
When rotating and cutting the decorative paper (1), in order to make the base material layer on the back side of the decorative paper (1) as thin as possible, stable cutting is possible by pressing lightly with a flat bar from above the edge of the decorative paper (1). Alternatively, the cutting blade (6) or the decorative board (10) may be tilted slightly to obtain a desired thickness difference by tilting the base material layer on the back side of the decorative paper; The desired substrate thin layer was obtained for the process.

[0011] Also, depending on the base material and hardness used, the cutting blade (6)
By changing the shape of the decorative laminate, it is possible to process the base material of the decorative laminate in a shape other than the semicylindrical shape. FIGS. 4 and 5 show cross-sectional views of decorative laminates manufactured according to this embodiment.

0012

[Effects of the Invention] The method of decorating both ends of a decorative board of the present invention is effective for decorating both ends of a decorative board that is laminated on both sides with decorative paper using tissue paper on particle board and medium-specific gravity fiberboard as a plate-like base material. do. In other words, by slanting and cutting the thin layer of base material on the back side of the surface decorative paper to create a difference in thickness, it is possible to improve adhesion to the base material and prevent the folding of the decorative paper with the thin layer of base material during adhesion. To prevent. Further, the joint portion with the back decorative paper is brought close to the limit, making it inconspicuous, and the decorative paper and the end side portions have a continuous sense of unity, making it possible to provide a decorative board that responds to luxury trends and has an excellent design. As an additional effect, the present invention provides a novel method for decorating the end portion of a decorative board that can be mechanically treated and has advantages such as productivity and cost reduction.
