Abstract

PROBLEM TO BE SOLVED: To express various kinds of lumber, keep a stereoscopic effect, and lessen waste of lumber in use of laminated lumber by disposing a transparent film of polyvinylchloride resin or the like with a grain pattern-printed layer formed by transparent ink on the laminated lumber via a transparent adhesive. SOLUTION: The laminated lumber 1 is made by the use of lumber sliced into a 300 μm thickness, nonwaven fabric is used for the lining paper 2, and the laminated lumber 1 is stuck thereto through an ethylene-acetate vinyl emulsion adhesive 3. An acrylic film of an about 50 μm thickness is used for the transparent film 4, a grain pattern-printed layer is formed on the rear surface by the use of a solvent type ink through gravure print, and unevenness 6 is formed on the surface by an embossing method. Then, the transparent film 4 is stuck on the laminated lumber 1 in use of a transparent adhesive 7 for forming a grain sheet. The grain sheet is suitably used for fixture material such as a fitting baseboard and strip flooring of a door or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a wood grain sheet,
More specifically, the present invention relates to a wood grain sheet capable of expressing a woody texture close to real wood used for surface decoration such as a fitting material, a building material, and a flooring.

[0002]

2. Description of the Related Art Logs are in short supply due to deforestation and other natural destruction, resulting in a rise in timber prices and a chaotic market.
Therefore, there is an increasing demand for surface materials having a wood grain pattern on veneer, laminated wood, vinyl chloride, and paper such as reinforced paper, titanium paper, and thin paper. However, veneer, laminated wood, and the like have a drawback that they can express only their own patterns, and vinyl chloride, reinforced paper, titanium paper, thin paper, and the like have a drawback that the three-dimensional appearance is insufficient.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a wood grain sheet capable of expressing various types of wood, having a three-dimensional appearance, and using a laminated wood to reduce waste of wood and reduce the burden on the global environment. Is to provide.

[0004]

That is, the present invention relates to a wood grain pattern formed by a transparent ink on a laminated material via a transparent adhesive, the surface of which is formed of a transparent ink which does not impair the timber and the skin of the laminated material on the back surface. A wood grain sheet having a transparent film made of a polyvinyl chloride resin, an acrylic resin, or an ethylene-vinyl acetate copolymer provided with a printing layer.

In the wood grain sheet of the present invention, a natural wood texture can be expressed because the wood grain pattern is printed using ink having high transparency which does not damage the wood and the peculiarities of the laminated wood. In addition, natural wood has various colors and textures, but wood grain pattern printing using a transparent ink can provide a large amount of wood with uniform color and texture at low cost. Furthermore, since the wood grain print layer is formed on the back side of the transparent film, the durability is excellent.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

[0007] As a glued laminated lumber, a suitable wood is set to a thickness of 10
What is sliced to about 0 to 1000 μm, preferably about 250 to 600 μm is suitably used.

The printing of the grain pattern on the transparent film is performed by gravure printing, and the ink used may be either a solvent type or an aqueous type.

[0009] The uneven pattern of the transparent film is formed by embossing.

[0010] A transparent adhesive is used to bond the laminated material and the transparent film. The adhesive only needs to have good transparency, and for example, ethylene-vinyl acetate, acrylic, urethane, rubber, epoxy, etc. can be used.

Further, in the present invention, a backing paper may be laminated below the laminated wood. Non-woven fabric, woven fabric, paper and the like can be used for the backing paper. By stretching the backing paper, the strength of the wood grain sheet is increased, and when the wood grain sheet is stuck to an arbitrary member, the influence of the color variation of the members can be reduced.

An adhesive is used to bond the laminated wood to the backing paper. As the adhesive, for example, ethylene-vinyl acetate, acrylic, urethane, rubber, epoxy, etc. can be used.

[0013] The wood grain sheet of the present invention thus obtained can be used for doors, doors and other fittings, building materials such as baseboards, rims and rims, as well as kitchens, furniture, closets, and system washbasins. It is suitably used for applications such as a table, ceiling, flooring, siding, and waist wall.

[0014]

1 and 2 are schematic sectional views showing the structure of a wood grain sheet according to the present invention. Hereinafter, an embodiment in which the backing paper of FIG. 2 is laminated will be described.

The laminated wood 1 was obtained by slicing wood to a thickness of about 300 μm.

A non-woven fabric was used for the backing paper 2 and bonded to a laminated material using an ethylene-vinyl acetate emulsion adhesive 3.

An acrylic film having a thickness of 50 μm is used for the transparent film 4, and a grain pattern printing layer 5 is formed on the back surface of the transparent film 4 by gravure printing using a solvent type ink.
Asperities 6 were formed on the surface by embossing.

This transparent film was bonded to a laminated material using a urethane-modified vinyl resin-based transparent adhesive 7.

[0019]

According to the present invention, a very natural feeling of material can be expressed by wood grain pattern printing using ink having good transparency and wood peculiar to glued lumber. In addition, since the grain pattern printing layer was formed on the back surface of the transparent film, the durability was excellent.
