Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to interior materials such as I-wood and H-RFA materials, and particularly to precious wood decorative boards developed as interior materials for extensions and renovations. In addition, the precious wood decorative board of the present invention can also be used as a surface decorative material for furniture, cabinets, etc., and decorative small boxes.

In recent years, decorative boards based on plywood have been increasingly used for wall and ceiling materials. This is done by peeling off the board from the wall, etc. and attaching a new decorative board.

However, with this method, the plywood base material often cracks and tears during peeling and remains on the wall material, etc., and it is necessary to remove this residual profit, making the renovation work troublesome. The shortcomings of the method were to replace the entire decorative panel, the renovation cost was high, and it was not economical. Therefore, as a simple and economical renovation method, there is a method of pasting a thin decorative plastic sheet or decorative wallpaper on the surface of the decorative board that is currently in use (or the surface of the decorative board from which the surface layer veneer has been removed). This has been done traditionally. but,
This method not only does not show the grain of the wood, which is unique to precious woods such as zelkova, on the surface of the interior material, but also tends to cause twisting, shrinkage, curling, etc. after pasting, and it is possible to paste a wide area with unevenness. It was difficult to put on clothes.

The present invention has been made in consideration of the above-mentioned circumstances, and its main purpose is to provide a decorative wood panel that can be easily and economically renovated and has a good finish.

Another object of the present invention is to provide a precious wood decorative board that is bendable and highly workable, and is useful for interior materials for curved parts and curved surfaces.

The decorative wood laminate of the present invention has a decorative laminate base material with kraft paper, a polyethylene layer, and a polypropylene layer arranged from the outside on the front and back sides, and aluminum inside the base material.
A laminate consisting of metal foil such as iron, a polyethylene layer or polypropylene layer, and paperboard, and this product,
A decorative veneer is pasted onto the surface of the base material via a thermosetting, thermoplastic, or fat adhesive, and the decorative veneer-base material laminate is heat-pressed or heat-pressed. It is particularly disliked that it is made by cold pressing. That is, by devising the base material, etc., it has appropriate rigidity and flexibility ratio,
This is an ultra-thin decorative board that is dimensionally stable and bendable.

Furthermore, the 4;6 decorative wood board of the present invention will be described in detail based on FIG. This is the result of normal continuation processing. The decorative veneer 2 is a hardboard made by thinly cutting various precious woods such as Japanese cypress, oak, zelkova, cherry blossom, teak, imported wood such as rosewood, walnut, mahogany, and zebra wood. . The veneer 2 has a grain such as straight-grain, cross-grain, board-grain, or heather, and is usually 02-1.0 llI#
+ The thickness of the thigh is used. Moreover, the adhesive 3 is
If it is a thermosetting 1 or Netsucho 113i adhesive and is applied in such a way that the adhesive itself does not ooze out from the surface of the unit, it can be compressed for use as a cosmetic and pasting agent. good.

Examples include water-soluble melamine imitation J fat, Sunalene-butadiene axis 'I Jlil, and the like.

As shown in FIG. 1, the base material 4 has a multi-layered structure, and each of its six-sided portions 5, interior 6, and curved portions 7 has a characteristic configuration. The surface portion 5 is composed of a sheet paper 8 and a polypropylene layer 9 arranged on the outside. The kraft paper 8 absorbs moisture in the adhesive 5,
On the other hand, the polyethylene or V-polypropylene layer 9 prevents the adhesive moisture from penetrating into the interior of the substrate. Therefore, the entire base material 4 swells and its rigidity decreases due to 5) 1. tL
has been done. From the point of
0 to 80 g/173", preferably about 50 g/173", and another sesame layer may be provided inside the polyethylene or polypropylene layer 9 to prevent moisture penetration.

The inside of the base material 6 is made of aluminum, metal foil 1G of iron cylinder, polyethylene fabric or polypropylene layer 11, and paperboard 12.
And so on. The 4M foil 10 has poor expansion and contraction due to the strong rigidity of Al, Fe, etc., and is used to maintain the dimensions of the base material plane (or the decorative board plane) constant. Also foil 1
0 has flexibility based on malleability such as All+Fe. The other base materials are also flexible and thin, which makes the decorative board 1 bendable. Further, the metal foil 10 is preferably waterproof for the decorative board 1 by 30 μm in order to limit the diffusion of moisture.

Neck, polyethylene t fc is polypropylene I so 11
By providing a plurality of polyethylene or polypropylene layers in the base material, alkali components are prevented from penetrating from the back surface of the base material to the chemical plate. Part 1c is particularly effective when the wall material is made of an alkaline material such as mortar.

Accordingly, the polyethylene or polypropylene layer may further increase in number. 7F is polyethylene.
The layer thickness of Mabo 3-pyrene FA11 may be approximately the same as that of the polyethylene or polypropylene layer 9 on the surface portion.

Further, the paperboard 121'i-, which forms the main thickness of the base material 4, gives the decorative board 1 181illness and flexibility. Leave, weigh 100-400 g/? /l
', preferably about 500 g/tyt'.

The base material surface portion 7, like the surface portion 5, has a layer of kraft paper 13, polyethylene or polyethylene layer 14 arranged from the outside. The kraft paper 13 absorbs moisture in the adhesive used to attach the decorative board 1, while the polyethylene or fcu
The polypropylene layer 14 prevents moisture from the adhesive from penetrating into the interior of the substrate. Due to the dual structure of kraft paper and a polyethylene or polypropylene layer, the adhesive board 1 is restricted from curling after swelling even if the adhesive is applied to the entire back surface. From this, the basis weight of the kraft paper 13 is 20 to 80 g/yy
t", preferably about 50 g/ln".

Then, the base material 4 (#i, for example, kraft paper 8, metal foil 10, paperboard 12, and kraft paper 13) having the above layered structure are laminated in sequence, and molten polyethylene or polypropylene is added between each material layer. The adhesive 3, which has been prepared and stirred in advance, is applied onto the surface of the laminated base material using a sprayer, etc. Decorative veneer 2 (previously cut to predetermined dimensions, etc.) is applied using a reverse footer, etc., and dried on top.
Then, 4 pieces of this decorative veneer-base material A' are put together one by one for a predetermined period of time (for example, 10 to 20 minutes).
Let it accumulate. Thereafter, when the adhesive 3 is a thermosetting resin, the laminate is heat-pressed to harden the adhesive 3 and compress the laminate into a thin layer. In this case, the conditions for heat compaction are, for example, a temperature of approximately 105°C.
It is preferable to carry out the process under conditions of a pressure of about 7, 9/ol% and a time of about 90 seconds. When the adhesive 3 is thermoplastic pine resin, the 8T layer f is compressed into a thin layer by bonding the M laminate to the plates by hot pressing and then cold pressing. In this case, the conditions for thermal compaction are, for example, a temperature of about 105°C and a pressure
After conducting under the conditions of k7/d1 time 120 seconds, cold 1-1
- Spinning is carried out at room temperature and cooling at a pressure of 1b1 of k(+/ol).

By using the above-mentioned paper, resin, and metal foil as the base material for the single precious wood decorative laminate thus obtained, it is much thinner, more flexible, and more flexible than a decorative laminate based on plywood. It has flexibility. On the other hand, compared to conventionally used decorative plastic sheets and decorative wallpaper, it is much stronger and more rigid. In addition, since it includes a metal foil layer and prevents moisture from penetrating into the base material, it has poor expansion and contraction, is less likely to be distorted or deformed due to the influence of moisture, and has excellent dimensional stability. Furthermore, since it is extremely thin and flexible, it can be easily bent and cut with nines or the like.

The present invention will be explained in detail below.

From the surface, kraft paper (Tsuboit "Og/"),
Polyethylene or polypropylene, aluminum foil (
Tsubo! 80 g/”), polyethylene or polypropylene, kraft cardboard (basis weight 300 g/w’), polyethylene or polypropylene, and kraft paper (
50 g/172") were laminated by a predetermined lamination process, and then cut to produce a base material with a predetermined size and shape. Approximately 12 g/172" of thermosetting resin adhesive was then applied onto the surface of the base material. va' was coated, and a desired decorative veneer was applied thereon, and then stacked for 8 minutes for 10 to 20 minutes.Then, this decorative veneer-base material J accumulation body was heated at a temperature of 105°C.
The decorative wood board of the example was manufactured by heat pressing under pressure for 974 hours and 90 seconds. The decorative board of the example obtained as a result was made of kraft paper with a thickness of 11.05 m+ from the surface,
20 μm thick polyethylene or polypropylene/i
