Abstract

PURPOSE:To obtain the wooden sheet which is usable as the object to be printed and moreover is not easily cracked by sticking a wooden veneer to at least one surface of the sheet base material such as paper, an unwoven cloth and a synthetic resin sheet, etc. CONSTITUTION:A wooden sheet is made by integrally sticking wooden veneers 2, 2 to both surfaces of the sheet base material 1 such as paper, an unwoven cloth or a synthetic resin sheet. For this wooden veneer 2, a natural decorative veneer made by slicing a log, or an aggregated decorative veneer may be used. In the aggregated decorative veneer, the color tone and the grain on the surface may be freely set so as to match the purpose and the letter or the figure to be printed. The stock veneer obtained by slicing a natural log is decolored, and after the dyeing in a prescribed color and the regulation of humidity, a plurality of the stock veneers 3 are laminated through an adhesive, and are mutually stuck by clamping, thereby forming an aggregates flitch 4. By slicing the flitch from the direction crossing a laminated surface, the aggregated decorative veneer 5 in which the pattern of straight grain is shown on the sheet surface is obtained. Accordingly, the strength of the wooden veneer is improved, and the cracks etc., can be prevented. Letters or graphics may be printed on the surface of the wooden veneer as the object to be printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a wood-based sheet that can be used as business cards, calendars, postcards, and other printed matter.

[Background technology]

Recently, the soft texture and feel of wood has been reconsidered, and more and more people are preferring to use wood-based materials in their daily lives. This trend is not limited to building materials such as flooring materials, but it has even been proposed to use wood-based materials as a substitute for paper for indoor interior items as well as printed materials such as business cards, calendars, postcards, and poetry collections.

However, even if a wood-based sheet made by simply slicing a natural material into thin slices is used as a printing material, it has the drawback of being weak against bending and easily cracking, resulting in poor handling properties.

[Purpose of the invention]

An object of the present invention is to provide a wood-based sheet that can be used as a printing material and does not break easily.

[Disclosure of the invention]

The wood-based sheet of the present invention is characterized by having a wood veneer adhered to at least one side of a sheet base material such as paper, nonwoven fabric, or synthetic resin sheet.

According to this invention, since the wooden veneer is attached to the sheet base material, the strength of the wooden veneer is improved and cracking can be prevented, making it easy to handle. It becomes possible to print and use characters, figures, etc. on the surface of the board.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 3. Figure 1 is an enlarged cross-sectional view of the wood-based sheet of this example.
FIG. 2 is a plan view thereof.

The wood-based sheet shown in Figure 1 is used as a mount for business cards, and wood veneers 2゜2 are integrally pasted on both sides of a sheet base material 1 such as paper, nonwoven fabric, or synthetic resin sheet. This is what I did. As shown in FIG. 2, the wooden veneer 2.degree. 2 has a straight grain pattern formed on its surface, and letters, figures, etc. are printed on the surface of the board.

It is appropriate to use a sheet base material l having a thickness of about 5 to 300 Ij.

The wood grain of the wood veneers 2 and 2 attached to both sides of the sheet base material l (
The fiber direction may be the same on both sides (or the front and back sides may be crossed (perpendicular)). If the grains are in the same direction, the wood will be easy to bend horizontally and strong vertically.
If they cross each other, they will be stiff both vertically and horizontally. Therefore, the direction of the wood grain can be selected depending on the use of the wood-based sheet.

It is appropriate that the wood veneer 2 has a thickness of about 0.1 to 1+em. The wooden veneer 2 can be a natural decorative veneer made by slicing raw wood or a laminated decorative veneer. Among these, laminated decorative veneer has the advantage that the color tone and grain of the surface can be freely set to suit the intended use and the characters and figures to be printed.

The laminated decorative veneer is manufactured as follows.

First, the raw material veneer 3 obtained by slicing natural wood is bleached, dyed in a predetermined color, and humidity controlled. As shown in Fig. 3, multiple pieces of raw material veneer 3 are laminated with adhesive. By compressing and bonding to form a laminated flitch 4 and slicing it in a direction intersecting the laminated surface (the slicing direction is indicated by a dashed line), a laminated decorative veneer 5 with a straight-grain pattern expressed on the board surface is obtained. is obtained.

In manufacturing such laminated decorative veneer 5, the material veneer 3 is impregnated with a water repellent to prevent ink from bleeding, or
Alternatively, the wood sheet may be made to bleed to an appropriate degree, or it may be impregnated with a fragrance to obtain a wood-based sheet with a pleasant fragrance. Impregnation with such a water repellent or fragrance can also be carried out easily.

Further, by adjusting the grain of the laminated decorative veneer 5 and the lamination angle, any beautiful "watermark pattern" can be imparted. Furthermore, since the laminated decorative veneer 5 is laminated and bonded with an adhesive, it can be manufactured to be less likely to break or break than natural wood materials. Moreover, it does not lose the texture and feel of wood.

In this example, the wooden veneer 2.2 was pasted on both sides, but the wooden veneer 2 may be pasted on only one side. In addition to the straight-grained pattern, any wood grain such as the board-grained pattern can be used.

〔Effect of the invention〕

According to this invention, since the wood veneer is attached to the sheet base material, the strength of the wood veneer is improved and cracking can be prevented, making it easier to handle. It becomes possible to print letters, figures, etc. on the surface and use it for business cards, calendars, etc.
