Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a veneer that has a painted appearance, that is, a veneer that gives the illusion that the veneer material has been painted, although it is not actually painted.

[Conventional technology]

Painted veneer material is painted and often lined with non-woven fabric to form painted veneer material, which is used in the manufacture of furniture and building materials. When manufacturing such painted veneer, simply painting the veneer material with a transparent colored paint will not give a deep painted feel, and if a low-grade veneer material is used, the surface will be exposed as is and the design will be poor. The obtained veneer cannot be subjected to bending processes such as V-cutting or ramping.

There is a technique that prints a pattern on a veneer material and then coats it with transparent colored paint 921, which allows you to use a low-grade veneer material and still have a certain appearance, and even use a high-grade veneer material. If so, the design quality will be further enhanced. However, in order to obtain a deep coating, it is necessary to repeat the coating many times, which increases the cost. This product also cannot be subjected to bending processes such as cutting or ramping.

[Problem that the invention seeks to solve]

The painted veneer of the present invention is characterized in that at least one colorless and transparent plastic film is laminated on one side of the veneer material with a colorless and transparent adhesive layer interposed therebetween.

As shown in FIG. 1, a typical 6m film according to the present invention is made by laminating a colorless transparent plastic film 3A on one side of a veneer material 1 with an adhesive layer 2B interposed therebetween.

In modification a, a pattern printing layer and/or an iSiI91 colored printing layer are provided on at least one of the surface of the veneer material, the surface of the adhesive layer, or the surface and/or back surface of the colorless transparent plastic film. .

In another embodiment, two transparent and colorless plastic films bonded together with an adhesive are used.

There may be three or more colorless transparent plastic films.

As the veneer material, a commonly used material having a thickness of about 0.1 to 1.0 mm, preferably about 0.1 to 0.3 mm is used.

It is convenient to line the back side with a non-woven fabric or cloth, as it makes it easier to apply the veneer of the product to a table, ceiling, wall, etc.

As the colorless transparent plastic film, films of ethylene-vinyl alcohol copolymer and ethylene-vinyl acetate copolymer are suitable. These films are
It has moderate heat resistance, excellent workability, and hygroscopicity.
Since it does not generate static electricity, it is suitable for housing materials. In addition, polyethylene, polypropylene, polyvinyl chloride,
Films such as polyvinylidene chloride, polyethylene terephthalate, polycarbonate, nylon, polystyrene, and polyvinyl alcohol can be used. The thickness is 0.
03-llll111 preferably 0.2-0.5aua
That's about it.

The adhesive layer is formed by applying a true melt adhesive such as ethylene-vinyl acetate copolymer, polyvinyl acetate, vinylidene chloride copolymer, polyvinyl acecool, polyvinyl butyral, etc. by any means such as extrusion coating method. .

If necessary, an anchor coat may be applied on the adhesive layer.

As a method for laminating the veneer material and the plastic film, hot press lamination and hot roll lamination are suitable. When thermally laminated using these methods, the adhesive layer melts and fills the recesses on the surface of the conduit and non-conduit parts of the veneer material, so there are no air bubbles left between the veneer material and the adhesive layer, and the adhesive layer is tightly bonded. Improves sex. Other lamination methods such as dry lamination, wet lamination, and semi-dry lamination can be used.

As the coloring agent for the adhesive layer and the transparent plastic film, commonly used pigments and dyes may be used.

The pattern printing layer and the transparent colored printing layer can be formed by any printing method such as gravure, offset, letterpress, etc.

[Effect]

Due to the presence of the colorless transparent plastic film, the painted veneer of the present invention can give the impression of being painted even though it is not painted. Using a thick colorless transparent plastic film,
Laminating multiple layers creates a deep coating effect.

With conventional painted veneers, it is difficult to perform bending processes such as cutting or wrapping because cracks appear on the painted surface, but the veneer of the present invention has a colorless transparent plastic film that can withstand bending. Therefore, bending processes such as cutting and wrapping can be easily performed.

Embodiments in which a pattern printing layer and/or a transparent colored printing layer are provided are even more attractive in terms of design.

Products in which the other side of the veneer material is lined with non-woven fabric or cloth are convenient for adhesive application.

[Example 1] A veneer having the configuration shown in FIG. 2 was manufactured as follows.

The transparent plastic film 3B is an ethylene-vinyl alcohol copolymer film "Eval"(Kuraray') lfllL with a thickness of 25 μm, and on top of that, a printing layer with a wood grain pattern is printed using gravure ink "Dye Ink" (Moroboshi Ink). , and was provided by a gravure stamp to form a pattern printing layer 6.

Subsequently, a transparent colored printing layer 5 was provided thereon.

On this transparent colored print N5, an ethylene-vinyl acetate copolymer hot melt adhesive was extrusion coated to a thickness of 50 μm via a urethane anchor coat to form an adhesive IJ2B.

Next, the surface of the oak veneer material 1 with a thickness of 0.15o+m lined with the nonwoven fabric 7 "Axter" (manufactured by Toshi ■) with a basis weight of 4αg/rd, and the surface of the adhesive layer 2B of the above laminate. were overlapped and heat press laminated to obtain a veneer.

The obtained veneer had a deep painted feel and could be easily bent.

[Example 2] A veneer having the configuration shown in FIG. 3 was manufactured according to the following steps.

A film similar to that in Example 1 was prepared as the transparent plastic film 3B. On top of that, gravure ink rS
A wood grain pattern was printed by gravure printing using "A Ink" (Showa Ink Kogyosho) to form a printed layer 6 of the pattern.

The surface of this printed layer and a 12 μm thick polyester film "Lumirror" (manufactured by Toshi O1), which is a transparent plus film, are bonded together using an adhesive "Fukerank Takenate".
(manufactured by Narita Pharmaceutical Industry i1i+) through an adhesive layer 2A formed using dry lamination. On the polyester film surface of the above-mentioned laminate, the same adhesive as in Example 1 was extrusion coated to a thickness of 30 μm via a urethane anchor coat 4 to form an adhesive layer 2B.

Next, the surface of the oak veneer material 1 lined with the same nonwoven fabric as in Example 1 and the surface of the adhesive layer 2B of the film were superimposed and hot press laminated to obtain a veneer.

The obtained veneer had the same performance as Example 1.

〔Effect of the invention〕

Although the painted veneer of the present invention is not painted, it has a deep painted feeling that gives the impression that it has been painted many times. Even if a low-grade veneer material is used, the product has a high design quality, and if a high-grade veneer material is used, a product with an even higher design quality can be obtained.

■This veneer can be easily bent, such as cutting and wrapping, so it can be used in a wide range of applications.
