Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a surface wood material by using an unsuitable wood which is not suitable for use as a surface wood material such as a laminated wood.

[0002]

2. Description of the Related Art Wood is used in a wide range of applications as a structural material for home construction, a decorative material, a member for furniture, and the like. For example, for pillars, lintels, and Nagasushi between houses in Japan, in order to make the most of the beauty of the material of the wood, wood with few knots that can be used with the surface as it is is used. Also in the western world, warm wood is preferred for the floor, and a material with a uniform color tone and uniform grain is used. Also for furniture, wood with a uniform texture and good workability is used.

[0003]

[Problems to be Solved] However, when used as a surface wood material such as a decorative material, all woods must satisfy the conditions that the ground surface is uniform and the wood grain is uniform. Inappropriate use of nonstandard wood that is out of the conditions has variations in color tone and grain, and the water absorption rate differs depending on the tree species.

Therefore, is inappropriate wood such as non-standard wood used for parts that are not directly visible, such as core material and base material?
Alternatively, the range of use is limited, such as being processed into laminated wood and used as a structural material. In addition, in order to protect the environment and prevent the depletion of wood resources, it is becoming more difficult to obtain good quality wood.

In view of the above conventional problems, the present invention can easily produce a high-grade surface wood material using unsuitable wood which is not suitable for use as a surface wood material such as laminated wood or surface fiber material. The present invention is intended to provide a method for producing a surface wood material.

[0006]

According to the present invention, unsuitable wood which is unsuitable as a surface wood material such as laminated lumber and surface fiberboard is used, and the surface of the unsuitable wood is embossed to obtain a surface pattern to be obtained. To form a concavo-convex pattern, then apply a concealing paint with a tone that erases the background color of unsuitable wood, dry it, and then apply a dark paint on the concealing paint and then wipe the surface, Then, there is a method for manufacturing a surface wood material, which is characterized by applying a top coat paint and drying.

What is most noticeable in the present invention is that the surface of unsuitable wood, which is unsuitable as a surface wood material, is embossed, and then a concealing paint having a color tone that erases the ground color of the unsuitable wood is applied. That is, painting, wiping treatment, and painting of topcoat paint.

In the present invention, the unsuitable wood is wood that is unsuitable for use as a surface wood material due to the surface appearance, physical properties, dimensions, etc. of each use site. Such wood that is invincible to use includes so-called low-grade wood such as wood fiberboard. Examples of unsuitable wood include laminated wood,
Wood fiberboard, unobtrusive wood, knotty wood,
There are veneer and plywood. Examples of the wood that does not have a noticeable grain of wood include Southern seawood such as agatis, alder, and rubber.

The surface of the unsuitable wood is first embossed to form an uneven pattern corresponding to the surface pattern to be obtained. Next, a masking paint is applied to the unsuitable wood and dried. The concealment paint has a color tone that erases the ground color of unsuitable wood. The color of the hiding paint is non-transparent,
And a light color will do. Specifically, although the bright color tone of the overcoating color system is good, it is preferable to paint in white in order to make the contrast between the dark color paint in the recesses and the overcoat paint that will be applied in the subsequent step clear. As the hiding paint, for example, a two-component polyurethane-based synthetic resin paint can be used.

The hiding paint is applied so that the embossed recess remains. In a later step, this recess is filled with dark color paint to form an embossed pattern. After coating and drying the above-mentioned concealing paint, it is preferable to polish the convex portion of the coated surface of the wood material. As a result, the surface of the concealing paint is made smooth, and when the wiping process is performed after the dark color paint is applied in the subsequent process, only the dark color paint in the recess can be left clearly.

Next, a dark paint is applied to the surface of the above-mentioned concealing paint. Use darker color paints such as black and brown. Next, a wiping process is applied to the coated surface of the unsuitable wood coated with the dark color paint. The wiping process is a process of scraping off the dark-colored paint on the convex portions of the irregularities on the surface formed by embossing and leaving the dark-colored paint in the concave portions as it is. The wiping process can be performed using, for example, a doctor knife. By applying the above-mentioned dark color paint and wiping treatment, the appearance defects of the surface of the unsuitable wood are made more inconspicuous, and the surface wood material in which the embossed pattern is emphasized can be obtained.

After the wiping treatment, a topcoat paint is applied to the surface of the unsuitable wood subjected to the wiping treatment and dried. The topcoat paint is preferably a paint having properties such as abrasion resistance, weather resistance, and adhesion. As such an overcoating material, for example, a two-component polyurethane coating material to which a pigment-based coloring material is added can be used.

Further, it is preferable that after the wiping treatment, a transparent sealer is applied, the surface is lightly sanded, and then the above-mentioned top-coat paint is applied. By this,
Similar to the process after the coating of the cover-up paint, the finish of the overcoat paint after coating can be improved. For the transparent sealer, for example, a two-component polyurethane sealer is used.

[0014]

In the method for producing a surface wood material according to the present invention, the surface of unsuitable wood is embossed, and a concealing paint having a color tone that erases the ground color of unsuitable wood is applied. Therefore, even if the unsuitable wood is a laminated wood made up of a plurality of scraps, it is possible to hide the difference in the ground color of each scrap. Therefore, the laminated wood looks as if it is composed of one continuous member, and can have a uniform surface color tone. Furthermore, even with unsuitable wood having a knot on the surface, the knot can be hidden by applying the above-mentioned hiding paint.

The surface of the unsuitable wood is embossed to form an uneven pattern. A concealing paint and a dark color paint are sequentially applied to the surface on which the uneven pattern is formed, and then the dark color paint on the convex part is scraped off by wiping treatment while leaving the dark color paint in the concave part of the uneven pattern. . Therefore, the concave and convex portions of the uneven pattern are dark and the convex portions are light colored, and the uneven pattern looks like a tissue appearing on the cross section of the wood.
There is a sense of quality.

Therefore, according to the present invention, it is possible to easily manufacture a surface wood material having a desired pattern by using an unsuitable wood as the surface wood material. Further, since an unsuitable wood, which is an inexpensive material, is used, it is possible to inexpensively produce a high-quality woody surface wood material.

According to the present invention, it is possible to easily produce a high-grade surface wood material using unsuitable wood such as laminated wood and surface fiberboard that is not suitable for use as the surface wood material.
A method for manufacturing a surface wood material can be provided.
