DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a decorative material in which a decorative sheet is laminated using a woody material such as plywood as a core material.

[0002]

2. Description of the Related Art Conventionally, window frames, blind frames such as members for sills / gates, water resistance as decorative materials for door materials, skirting boards, peripheral edges, etc.
Although plywood is used in terms of workability, strength, etc., it is not directly laminated with a decorative sheet on the portion including the lip of the plywood.

[0003] Because the plywood is made by laminating veneers with a cross (that is, alternately laminated so that the fiber directions are orthogonal to each other), when the dimensions change due to moisture absorption or the like, the expansion and contraction rate in the fiber direction is reduced. Because of the difference, there is a point that the wood opening becomes uneven and the smoothness is inferior, and there is a defect such as a tunnel peculiar to the plywood. Therefore, when a thin sheet is directly adhered, the unevenness appears on the surface and the design is poor. The same applies to lumber, particle board, OSB, bagasse board, etc., which have irregularities or defects on the cut edge.

[0004] Therefore, conventionally, in the case of a thin object such as a baseboard, as shown in FIG. 4, a decorative sheet (s) is laminated on a flat plate (p) made of plywood or MDF of 2.5 to 4.0 mm or the like. (A in the same figure), cut the flat plate part into V shape according to the final shape
(v) (b in the same figure), bending and bonding (c in the same figure).

In the case of a thick material such as a window frame, as shown in FIG. 5, a decorative material is manufactured by further attaching the decorative sheet (s) and the laminated plate material (p) to the core material (c). I was However, in this method, a V-cut (v) is applied to a portion of the flat plate (p) located at the corner of the core (c), and the end of the flat plate (p) is also applied to the core (c). A notch (c1) for winding the part must be provided, and there is a problem that processing is troublesome and an expensive flat plate is required.

Unevenness cannot be sufficiently prevented with respect to (1), and the smoothness does not change even if it exceeds 2.0 mm.Conversely, if it is thicker, unevenness on the tip (10) is more likely to occur and cost Also increase. As the surface material (2), vinyl chloride, ABS,
Resin-based sheets such as olefins, reinforced paper, resin-impregnated paper, veneer, MDF, and the like, and have a smooth surface to the extent that no irregularities occur on the sheet surface when a decorative sheet (3) described below is attached. When the face material is cut, a material that does not have noticeable unevenness is also preferably used.

In the present invention, the core material of the face material (2)
(1) It is preferable that the affixation to the wood edge (10) is usually performed with an adhesive or the like known in the art. As the adhesive, a vinyl acetate resin, hot melt, reactive hot melt, or the like is used.

The decorative sheet (3) used in the present invention includes:
It is a flexible general one that has been used in the past,
Any material may be used as long as it has a sufficient material and thickness to protect and decorate the core material, but a cosmetic material usually used in the art is preferable, for example, a thickness of 0.02 to 1.0. In addition to a synthetic resin decorative sheet of a vinyl chloride resin, a polyolefin resin, an ABS resin or the like having a thickness of about mm, a coated paper or a composite sheet thereof is suitably used. However, it is not particularly limited to these.

The decorative sheet (3) is subjected to a treatment on its rear surface so that it can be adhered to the substrate surface by pressing. As the adhesive used for this, an adhesive suitable for each adherend is selected.For example, a room temperature such as urethane resin, epoxy resin, vinyl acetate resin, modified vinyl acetate resin, vinyl urethane resin, etc. A curable adhesive, a hot melt adhesive such as an ethylene vinyl acetate resin, a reactive urethane, or a polyolefin can be used.

The wrapping of the decorative sheet (3) on the core material is performed by a method known in the art, such as pressure bonding using a flat rubber roll, a forming roll, or the like. The decorative sheet (3) covers the face material (2) attached to the decorative wood mouth (10a), and is slightly wound around the back surface (13) on the decorative wood mouth side, and at least the decorative face of the core material (the decorative wood face) , Surface).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments, but the present invention is not limited thereto. FIG.
3 to 3 are process explanatory views illustrating steps of the production method of the present invention. In these figures, (1) shows a plywood core material, (2) shows a face material, (3) shows a decorative sheet material, and (A) shows a decorative material.

The plywood core material (1) is formed by cross-bonding five veneers (11), and the fiber cross section of each veneer (11) is exposed at each peripheral end surface (10). The running surface (11a) and the running surface (11b) in the fiber direction alternately overlap. Therefore, in this state, unevenness due to the difference in elongation at the time of moisture absorption easily occurs on each end face (10) depending on the direction of the woody fiber. In addition, a so-called tunnel (11c) in which a part of wood is partially lost may also occur on the end face (10) (see FIG. 1).

With respect to such a plywood core material (1), 0.2 to 2.
A flat surface material (2) having a thickness of 0 mm, for example, a vinyl chloride resin plate is stuck to the decorative surface (10a) of the end surfaces (10) using, for example, a reactive hot melt adhesive (FIG. 2). reference). The present embodiment is used for a window frame, and since the cut edge of one side is not visible, the face material (2) is adhered to only one side. It is more preferable that the face material (2) is chamfered (2a).

With respect to the plywood core material (1) which has been subjected to the end surface smoothing treatment with the face material (2) as described above, its decorative surface (a decorative edge,
A decorative sheet (3), for example, a synthetic resin decorative sheet such as a vinyl chloride resin, a polyolefin resin, an ABS resin, or the like having a thickness of about 0.02 to 1.0 mm is laminated on the surface. In addition, the decorative sheet is not laminated, but the decorative sheet is also laminated on the wooden surface to which the surface material is not attached due to the problem of waterproofing. Above decorative sheet
(3), on the back surface, for example, urethane resin, epoxy resin, vinyl acetate resin, modified vinyl acetate resin,
Using a cold-setting adhesive such as a vinyl urethane resin or a hot melt adhesive such as an ethylene vinyl acetate resin, it is preferable that a treatment capable of bonding to the surface of the plywood core material (1) by pressing be performed. .

In the above-mentioned lamination, for example, pressure bonding using a flat rubber roll can produce a beautiful finish without wrinkles or the like. As described above, the decorative material (A) is easily manufactured. Furthermore, since the decorative sheet is rolled up to the back side of the face of the decorative wood, the face material is completely covered with the decorative sheet, and there is no uncomfortable feeling even when different kinds of materials are combined.
