につき種々研究がなされている。Conventional technology There are extremely few pieces of pine wood that have good grain contrast and are called fine wood, and generally have some kind of defect, large or small, and the wood grain contrast is not sharp. For this reason, various studies have been conducted on methods of making materials similar to precious wood by using such general, inexpensive materials and subjecting them to some kind of processing.

粧板が知られている。 One of the typical methods is to
A relatively low-grade softwood veneer such as rice cedar is used, and its surface is ground by brushing to create a wood grain pattern with concave areas in the relatively soft spring wood and convex areas in the hard summer wood. A decorative board is known in which the surface is processed to have an uneven surface, and then the concave portions are painted with a spring wood color and the convex portions are painted with a summer wood color.

りいかにも２色刷のように見えるためである。Problems to be Solved by the Invention However, with this method, a relatively natural finish can be expected since the wood grains are narrow in the case of straight-grained wood, but there was a drawback in that it was not possible to express a natural appearance in the case of straight-grained wood. The reason for this is that the grain of the board is significantly wider than the straight-grained wood in both the spring wood and summer wood, so if you paint the spring wood and summer wood colors respectively,
Although the contrast becomes stronger, not only does it end up being monotonous, but the boundary between the spring wood color area and the summer wood color area is too sharp, making it look like a two-color printing.

と知見し得た。 In order to solve the above-mentioned problems, the present invention has made the following findings as a result of intensive research. In other words, if you observe this in detail, natural wood has a structure in which one side of the board, especially in the grain area, and at the boundary between the summer wood and the spring wood, slips under the other. Therefore, on one side of the summerwood area, the color tone changes gradually from the dark summerwood area to the light-colored springwood area, while on the other side, the color tone changes relatively rapidly. It was found that there were parts with clear boundaries.

により貼着して用いる。 First, the wood used for the decorative original board 5 may be any wood as long as it has wood grain, but there is a clear distinction between the soft spring wood part 3 and the hard summer wood part 1, and the relative density Tree species with large differences, for example, softwood materials such as cedar, pine, Japanese pine, Japanese cedar, and Japanese toga can be suitably used. Although it is possible to use such wood as it is as a board material, etc., it is most commonly used in wood with a thickness of 0.2 to 1.5 mm, as shown in Figure 2.
A thin plate 10 of approximately
It is used by pasting it.

In order to process the spring material portion 3 into the recessed portion 4, it is easiest to process the surface by brushing and grinding the surface with a roll-shaped metal brush, a nylon brush, etc., but the method is not limited to this. , for example, blasting with abrasive material,
Alternatively, the surface may be formed into an uneven shape by compressing wood through an elastic body and pressing the soft spring material into depressions. By forming the depth of the recess 4 to be approximately 0.1 to 0.5 mm, the desired effect can be expected to be excellent.

The coating means is not particularly limited, but for example, it is advantageous to use a sponge roll coater. Of course, this spring material color coating layer 6 only needs to be applied to at least the concave portions 4, and does not necessarily need to be applied to the convex portions 2. Therefore, after coating the entire surface in advance as described above, the paint on the convex portions 2 may be scraped off or removed using an iron roll or the like as a reverse roll. The coating amount of this spring wood color coating layer 6 is preferably about 35 to 45 g/m 2 when the entire surface is coated.

A plurality of unit coating layers 9a, 9b, 9
Divide into c and apply and form in stages.

Color coating is performed in stages by sequentially changing the coating width of 9c. . On the other hand, in the other side edge where a rapid change in color tone is desired, the stepwise change is made small, and at least one of the unit coating layers 9a, 9b, and 9c, particularly preferably the top layer. A thick coating part 9c' is formed on one side edge of the darkest unit coating layer 9c, thereby creating a dark colored band 11 on the board surface along one side edge of the wood grain. .

もつて足る。 The number of layers to be applied to the summer wood color coating layer 9 is arbitrary, but it is an important issue as it relates to the finish. The width of the summer wood part of the grain varies considerably depending on the tree species, individual logs, and cutting method, so it must be determined based on the average grain condition of the decorative base board used. In general, if the width of the summerwood is narrow, or if the wood grain is so-called bamboo heather, it is sufficient to use two stages, and if the grain is coarse, it is better to use four stages. This is related to the concentration of the coloring material and cannot be generalized, but it is preferable to minimize the difference in color when applied, as this will result in smoother color tone changes at each stage. Each unit coating layer 9a, 9b, 9c in the summer wood color coating layer 9
There is no particular limitation on the width, and the stepwise change width of the coating layer width on one side of the convex portion 2 may be at equal intervals or may be at irregular intervals. Furthermore, the formation of the portions in which the coating layer widths of the unit coating layers 9a, 9b, and 9c are changed in stages as described above does not necessarily need to be formed on the entire decorative board, but at least on the main grain of the board. It is sufficient that the convex portion 2 is formed only on one side thereof.

の夏部材色になつていればよい。 The stepwise painting of the summer wood color coating layer 9 as described above is as follows:
It is not necessarily necessary that the color applied later be darker, and it is not necessarily necessary that the unit coating layer applied later be narrower than the unit coating layer applied first. In short, if the unit coating layers 9a, 9b, 9c overlap more and more as you go to the top of the layered coating, it will appear darker, and if it becomes the predetermined summer color. good.

一部逆にすることもある。 The coating method for the summer material color coating layer 9 is not particularly limited, but may require a roll coater, a gravure offset printing machine, etc. In either case, the desired coating can be achieved by adjusting the rubber hardness, printing pressure, and coating amount. can be administered. Specifically, when applying the summer wood color coating layer 9 in two stages, first the top and slopes are coated with a rubber roll with a rubber hardness of 60 to 70 degrees, and then the rubber hardness is 60 to 70 degrees.
Apply the paint to the top using a rubber roll at 80-90 degrees with less printing pressure. When the color coating layer 9 of the summer wood part is in three stages, a rubber hardness of 60 to 70 is applied between the two rubber rolls.
Apply the paint from the top of the slope to the top using medium pressure. The coating amount by these roll coaters is 8 to 12 g/m 2
It is. Note that, depending on the case, the order of these coatings may be partially reversed.

のである。 These spring wood color coating layer 6 and summer wood color coating layer 9 are formed of transparent or translucent paint as described above. The coloring agent used for this purpose is a transparent pigment or dye. Other pearl pigments may be added as appropriate. This is an attempt to express the luster of natural wood using the pearlescent luster of pearl pigments.

状濃色部が形成される。 To form this band-like dark colored part, the rubber hardness is usually
This can be easily achieved by using a coating machine, ie, a natural or reverse type roll coater, using a rubber roll with an angle of 70 to 90 degrees and in which the circumferential speed of the coating roll is relatively faster or slower than the feed speed. With this coating machine, the colored paint adhering to the coating roll is scraped off by the convex parts of the decorative base plate, so more colored paint is applied near the top than the top, resulting in a dark band-like color that is darker than the top. part is formed.

Each can have different finishes. Note that it is not necessary to form this band-shaped dark colored portion over the entire wood grain, and it may be formed only on a portion. It is desirable to vary the width as much as possible.

ある。 It is preferable to further apply a color clear coating on these colored coating layers 6 and 9 to adjust the overall color, and this color clear is used as a sealer to form the overall surface protective film 15. Good too. The type of overall protective coating 15 is selected depending on the purpose of the decorative board. For example, if it is a flooring material, it should have a certain degree of smoothness, abrasion resistance, and weather resistance. In view of this requirement, the recesses are filled to some extent with polyester resin or the like to give the surface a smooth or nearly smooth surface, or a sheet impregnated with a transparent resin such as diallyl phthalate is hot-press-molded to give the surface a smooth finish. shall be. In addition, when used as a wall material, surface smoothness is not particularly required, so it may be coated with aminoalkyd or polyurethane resin paint two or three times using a flow coater or spray coating method. In this case, the coating amount is usually about 60 to 70 g/m 2 .

つた。Effects of the invention The effects of this invention are as follows. First of all,
Since the original spring material color coating layer is applied to the concave portions of the decorative base board, it is possible to hide the defects that often occur in the spring material to some extent, and it is also possible to match the colors of a large number of products. Lot sorting by different colors,
Eliminates the need for lot sales. In addition, the color coating layer for the summer wood area, which is determined from the slope on one side of the convex part of the summer wood area of the decorative base board to the top, is applied in stages by changing the coating layer width of each unit coating layer so that it becomes darker toward the top. Since the wood has been applied in a targeted manner, when you look away, the color appears to change seamlessly at the boundary between the spring wood and summer wood, giving the appearance of a blur similar to that of natural wood. On the other hand, on the other side edge of the convex part, a band-shaped dark colored area is formed by the thick painted part of the unit coating layer of the summer wood color coating layer, so the border with the spring wood area is formed at the side edge. This emphasizes the wood grain and creates a contrasting decorative surface that makes the wood grain appear three-dimensional. This eliminates the disadvantages of conventional methods of coloring the wood grains, such as the monotony and appearance of two-color printing, and allows even wide wood grains to produce the same color change as natural wood grains. It is now possible to provide decorative panels that

とができる。 Further, according to this invention, the summer wood part can be made any dark color by taking into account the relative relationship between the color of the spring wood part and the color of the summer wood part, and the contrast between them can be increased and the high-quality wood is used. It can be made to have a deep and beautiful appearance with a wood grain that is similar to that of a wood grain. Moreover, although it is colored based on both the spring wood and summer wood parts, since it is painted using transparent or semi-transparent paint, it is possible to avoid imperfections in the wood fabric and color tone. The color of the summer wood part can be seen through to some extent, especially in the sloped part, and the beautiful luster of the wood is not lost, making it possible to make the fabric look fresh.

のとすることができる。 Furthermore, since the wood decorative board of the present invention uses natural wood as it is as a decorative base board, the wood grain is extremely varied, rather than having a monotonous, repetitive pattern like printed plywood. Furthermore, since the decorative base plate is textured through processes such as brushing, even when it is colored and painted, even if it appears to be the same color tone, complex shading is formed due to minute irregularities, and as mentioned above, Since the coating is applied to make use of the fabric, the product of the present invention has subtle changes that cannot be obtained with printed plywood or simply painted decorative boards, and has a beautiful appearance that closely resembles that of natural precious wood. can be presented.
