Abstract

(57) [Summary] [Purpose] The surface of a decorative panel with a wooden pattern, which is printed directly on the base material or laminated with a plastic film with a printed wooden pattern, has a visible light reflection that is equivalent to that of a natural wood surface. Because there was no diffused reflection, it was not possible to fully reproduce the texture and depth that is unique to natural wood. [Structure] The back side of the lauan veneer (2) is lined with a non-woven fabric (1), and the surface is laminated with a transparent resin layer (3) made of a 0.5 mm thick polyvinyl chloride sheet with a light transmittance of 95%. A wooden pattern decorative panel made by laminating a 0.1 mm thick polyvinyl chloride sheet (5) with an eye-printed layer (4) on the surface with the printed side facing the back side.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention can be used for furniture, interiors of buildings, interiors of cars, surfaces of home appliances, etc. Regarding wood pattern decorative panels.

0002

[Conventional technology]

In recent years, natural wood has become scarce and therefore expensive. Also, natural wood Because it is a natural product, it is not possible to obtain stable and uniform quality, color tone, and pattern in large quantities. It is difficult to For this reason, natural wood with the desired quality, tone and pattern is generally used. The manuscript is made into plates, and printed on titanium paper, thin paper, or vinyl chloride paper using normal printing methods. This is printed on a sheet, etc., and then laminated or impregnated onto the base material. The company was manufacturing decorative panels with wooden patterns.

0003 However, these wood-patterned decorative panels cannot express the tones and patterns of natural wood. However, it is difficult to express the luster called texture and the sense of depth that are unique to natural wood. It was. Pearl is added to conventional ink to express the texture and depth unique to natural wood. There are ways to use pigments, metallic pigments, etc. to increase brightness, but they still have the unique characteristics of natural wood. Terri, I couldn't express the depth.

0004 Therefore, although it is possible to express the tones and patterns of natural wood using only printing methods, The idea that it is impossible to express the depth and depth of existence has become mainstream. In recent years, as an improvement on these, natural wood, veneer, plywood, etc. have been used as base materials to make natural wood special. I came up with the idea of expressing the depth of existence.

[0005] The color tone and pattern are expressed using printing methods, and the texture and depth are expressed using a natural wood base. The natural wood base material is natural wood veneer such as lauan. Alternatively, print directly onto the natural wood substrate using plywood, etc., or use a wood pattern. It is laminated with printed plastic film.

[0006]

[Problem that the idea aims to solve]

The texture and depth unique to natural wood are due to the unevenness of the natural wood surface that is overwhelmingly greater than the wavelength of visible light. The reflection of visible light on the natural wood surface is caused by turbulence with different angles of incidence and reflection. This is caused by reflection, but as mentioned above, lauan etc. are added to the base material. Uses natural wood veneer or plywood, etc., and prints directly on the base material or prints a wood pattern. Even if you laminate a plastic film etc. with However, since the reflection of visible light does not become as diffuse as on the surface of natural wood, It is impossible to fully express the texture and depth of wood, which is unique to natural wood. The quality decorative panel has been eagerly awaited by the industry and consumers. As mentioned above, the present invention To provide an inexpensive wood decorative panel that has the texture and depth unique to natural wood. With the goal.

[0007]

[Means to solve the problem]

The present invention solves the above problems by providing a surface with a thickness of 0.3 mm or more on the surface of the wooden base material, allowing light to pass through. A transparent resin layer with a coverage of 80% or more is provided, and a printed layer with a wooden pattern is provided on the transparent resin layer. By laminating transparent films such that the printed layer is on the transparent resin layer side. That's what was solved.

[0008] Here, as the transparent resin layer, polyvinyl chloride, polypropylene, polyvinyl chloride, Thermoplastic resins such as ethylene are suitable. Furthermore, the light transmittance of the transparent resin layer and , the light transmittance of the transparent film having a printed layer of a wooden pattern on the transparent resin layer is equal to It is desirable that the This is because the light transmittance of the transparent resin layer and the There is a difference in the light transmittance of transparent films that have a printed layer of wood patterns on a transparent resin layer. Then, the transparent resin layer and the transparent film having a printed layer of a wooden pattern on the transparent resin layer are formed. Visible light rays are refracted at the boundary of the frame, and the effect of the present invention, which will be described later, cannot be fully obtained. That's because there isn't. Due to the necessity of V-cut processing, bending processing, etc., the above-mentioned The transparent resin layer can be used with a preferable thickness of 0.3 mm or more and 1 mm or less. Ru.

[0009]

[Effect]

Transparent resin with a thickness of 0.3 mm or more and a light transmittance of 80% or more on the surface of the wood base material layer By creating a layer, the visible light that is diffusely reflected on the surface of the wood base material layer is As it passes through the transparent resin layer while being held, the transparent resin layer with a printed wooden pattern on the transparent resin layer is Diffuse reflection from the surface of the wood base material can be applied to the bright film.

【Example】

Hereinafter, the present invention will be explained in detail based on the drawings. Figure 1 shows the wooden pattern of this invention. FIG. 2 is a stacked cross-sectional view showing an example of a decorative panel. Non-woven fabric on the back side of the lauan veneer (2) (1), and the surface of the lauan veneer (2) is made of polyvinyl chloride. A transparent resin layer (3) with a diameter of 0.5 mm and a light transmittance of 95% is laminated. Polychloride with a thickness of 0.1 mm, with a cheek print layer (4) on the surface of the layer (3) Laminated so that the cheek print layer (4) of the vinyl layer (5) is on the transparent resin layer side. This is a decorative panel with a wooden pattern made of teak.

[0011] Here, as a comparison test, if the light transmittance of the transparent resin layer (3) is set to 75%, The desired texture becomes poor, and when the thickness of the transparent resin layer is set to 0.25 mm, the desired texture becomes poor. I couldn't get any depth.

0012

[Effect of the idea]

As explained above, the present invention has a surface of a wooden base material with a thickness of 0.3 mm or more and a light-emitting device. A transparent resin layer with a linear transmittance of 80% or more is provided, and a wooden pattern is printed on the transparent resin layer. Laminating transparent films having layers such that the printed layer is on the transparent resin layer side. It has the same texture and depth as natural wood. By using natural wood veneers such as wood veneers or plywood, costs can be reduced. It is possible to provide a decorative panel with a wooden pattern and a high design quality.
