JPS6064885A - Wooden dressed plate - Google Patents

Abstract

PURPOSE:To obtain a dressed plate which has an external appearance similar to natural wood which is not seen as 2-color printing even in a wide grain of wood by coating color to produce stepwise color halftone in the boundary between a spring metarial portion and summer material portion. CONSTITUTION:A spring material portion coloring layer 6 with transparent or translucent spring material color coating material colored with spring material color is formed on the entire irregular surface of a prime decoration plate machined so that the summer material portion becomes raised portion 2 and the spring material portion 3 becomes recess 4. Then, a summer material coloring layer 9 with transparent or translucent summer material color coating paint from the oblique portion 7 to the top 8 of both sides of the raised portion 2 is stepwisely coated over a plurality of unit coating layers 9a-9c so that the portion becomes dense toward the top 8. The portion for stepwisely varying the width of the coating layer of the layers 9a-9c is formed at least on the essential portion of the grain of the wood.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wood decorative board that is colored to have a clear contrast wood grain pattern, giving it the appearance of a high-quality board.

In pine vJ, etc., there are very few pieces of wood that are called precious woods with good grain contrast and no peculiarities, and generally they have some kind of defect, large or small, and the contrast of the wood grains often cannot be spliced. For this reason, various studies have been conducted on methods of making materials similar to precious wood by using such common inexpensive materials and subjecting them to some kind of processing.

One typical method is to use a relatively low-grade softwood veneer such as Japanese pine or Japanese cedar, and grind the surface by brushing, etc., to create recesses in the relatively soft spring wood. Decorative boards are known in which the hard summer wood is processed into an uneven surface that follows the wood grain pattern as convex parts, and then the concave parts are painted with the color of the spring wood and the convex parts are painted with the color of the summer wood. .

However, with this method, a relatively natural finish can be expected with straight-grained wood because the grain is thin, but there was a drawback that it was impossible to achieve a natural appearance with board-grained wood. The reason for this is that the width of the spring wood part and summer wood part of the grain of the board is significantly wider than that of the straight grain, so if you paint the spring wood part color and the summer wood part color respectively, the contrast will be strong, Not only does it end up being monotonous, but the boundaries between the colored parts of the spring wood and the colored parts of the summer wood are too clear.

This invention is an attempt to solve the above-mentioned problems, and as a result of intensive research, the present inventor has found that in natural wood, at the boundary between the summer wood and spring wood, one is under the other. Since the structure is such that it sinks into J5, the color tone change is gradual, resulting in so-called blurring. The present invention was completed by discovering that a decorative board with an appearance similar to natural wood could be obtained by applying a colored coating to prevent the formation of wood.

The present invention provides a decorative original board (
In 5), the four parts (4) are coated with a spring wood color coating layer (6) using transparent or translucent spring wood color paint, and the convex part (2>) has slopes on both sides. From the surface (7) to the top (8
) The summer wood color coating layer (9), which is applied to a transparent or translucent summer wood color paint, has a plurality of unit coating layers (9a) (9b) (
The summer wood color coating layer (9) is formed in the layered manner of 9c), and the summer wood color coating layer (9) is such that the summer wood color becomes darker as it goes from the slope (7) to the top (8). The convex portion (
Unit coating layer (9a) (9
1)) This is an essentially decorative board characterized by the coating layer width of (9C) being varied.

Hereinafter, embodiments of the present invention will be described with reference to illustrated embodiments.
And for convenience of explanation, l! ! ! This will be explained in accordance with the order of the I-making process.

First, the wood used for the decorative base board (5) may be of any type 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). Therefore, tree species having relatively different densities, such as softwood materials such as cedar, pine, Japanese pine, Japanese cedar, and Japanese toga, can be suitably used.

Although such wood can be used as it is as board material, etc., it is most commonly used with a thickness of 0.2 to 1.5 mm Pi!, as shown in Figure 2. Process the thin plate (10) into a thin plate (10), and use it as an appropriate base material (11) such as plywood, hardboard, partiflubonide, laminated board, inorganic plate, metal plate, etc.
It is used by adhering it to the surface using a known adhesive (12).

The surface of this decorative original plate (5) is covered with a summer wood part (1) and a convex part (2).
), processing the spring material part (3) to become the fourth part (4) can be done most simply by brushing and grinding the surface with a roll-shaped metal brush or nylon brush. The surface is not limited to this, but may be formed into an uneven surface by, for example, blasting by spraying an abrasive material, or pressing by compressing the wood through an elastic body and causing the soft spring material to cave in. The desired effect can be expected by forming the fourth part (4) to a depth of 0.1 to 0.5 mm as a VI mark.

Next, as shown in Fig. 3.4, the entire uneven surface of the decorative original plate (5) is coated with a transparent or semi-transparent spring wood coating agent '31 colored in the spring wood color. Apply a partial color coating layer (6). This coating method is not particularly limited, but
For example, sponge roll coater C painting is the most convenient method. Of course, this spring material color coating layer (6) only needs to be applied to at least the concave portions (4), and not necessarily to the convex portions (2).
) need not be painted.

Therefore, after painting the entire surface in advance as described above, the convex portions (
2) The paint on the surface may be scraped off or wiped off using an iron roll or the like as a reverse roll. The application amount of this spring wood part color coating IZ (6) is preferably about 35 to 45 g/TIL when the entire surface is coated.

Incidentally, prior to forming the spring material color coating layer, a low-viscosity transparent paint may be applied to form a suction prevention layer.

Next, a transparent or semi-transparent summer wood color coating 1 is applied to the summer wood color (layer ( 9), the top (8
), multiple unit coats H(9a) (9
b) (9c) Form the coating in stages for k-minutes G:J.

The number of summer color coating layers (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, the individual logs, and the 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 summer wood is narrow, so-called bamboo-grained wood, it is better to use two steps, and if the wood is coarse, it is better to use about four steps. Although it is not possible to make a general statement because it is related to the amount, it is preferable to make the difference very small when it is painted, as this will result in a smooth color tone change at each stage. There is no particular limitation on the width of each unit coating layer (9a> (9b) (9c) in the summer wood color coating layer (9), and even if the stepwise change width of the coating layer width is equal intervals, , may be irregularly spaced. Also, the above J:
Unit coating layer (9a) (9b) (!lc) (D) The formation of the portion in which the coating layer width is changed in stages does not necessarily have to be formed on the entire decorative board, but at least on the grain of the board. It is sufficient that it is formed only in the main part.

In the stepwise painting of the summer wood color coating layer (9) as described above, it is not necessarily necessary to cover the color applied later with a darker one, and the unit coating layer applied later is not necessarily higher than the unit coating layer applied earlier. There is no need to call it narrow width. To cover the entire area, apply multiple coats, and finally apply unit coats toward the top (9a> (9b)
It is sufficient that the overlap of < 9c) increases, thereby making it appear darker, and that it has a predetermined summerwood color.

The coating method for the summer wood color coating layer (9) is not particularly limited, but
A roll coater, a gravure offset printing machine, etc. can be used, and J: Rimeru coating can be applied by adjusting the rubber hardness, printing pressure, and coating amount. Specifically, when applying the summer wood color coating layer (9) in two stages, the top and slopes are first painted with a rubber roll with a rubber hardness of 60 to 70 degrees, and then the top and slopes are painted with a rubber roll with a rubber hardness of 80 to 90 degrees. Paint the top part with less printing pressure.

When the summer moon color coating layer <9) is to have three stages, the above-mentioned 2.
Insert a rubber roll with a rubber hardness of 60 to 70 degrees between each call of real rubber, and use intermediate Ig and t' printing pressures to cover the slope from the top to the top.

The coating ml with these roll coaters is 8 to 129
/ml. In addition, depending on the case, the order of these coatings may be partially reversed.
It is preferable to use a gravure off-printing machine for printing, as this makes it possible to express partial dimness.
, J: It is possible to create a product that approximates the appearance of natural wood.

These spring wood color coating layer (6) and summer wood color coating layer (9) are formed by the transparent or translucent coating 1 as described above. The coloring agent used for this purpose is a transparent pigment or dye. Other pearl emulsifiers may be added as appropriate.

This is an attempt to express the luster of natural wood using the pearly luster of pearl pigments.

It is preferable to further apply a color clear coating on top of these colored coating layers (6) and (9) to adjust the overall color.
) may be used as a sealer to form. The type of overall retaining film (13) is selected depending on the purpose of the decorative board. For example, if it is a floor material, it should have a certain level of smoothness, abrasion resistance, and weather resistance. In view of this requirement, the four parts are filled to a certain extent with polystellate resin or the like to give the C surface a smooth or nearly smooth surface, or the sheet is impregnated with resin that can be made transparent such as diallyl phthalate by hot pressure molding. The surface shall be finished smooth. In addition, when used as a wall material, surface smoothness is not particularly required. C: If the material is coated with amino alkyd or polyurethane resin 1, it is coated 2 to 3 times using a flow coater or spray coating method. Also good. In this case, coating (6) is 60-70g/T
It Pi! It is normal to take it as a degree.

The effects of this invention are as follows. First of all, since the original spring wood color coating layer is applied to the four parts of the decorative base board that consist of the spring wood parts, it is possible to hide the defects that often occur in the spring wood parts to a certain extent, and it is also possible to have a wide variety of colors available for products. This eliminates the need for lot sorting and lot sales based on different colors. In addition, the summer wood color coating layer, which is applied from the slope to the top of the convex part of the summer wood part of the decorative base board, becomes warmer as it goes toward the top. Since it is applied to the wood, if you look away, you can see that the color is changing seamlessly at the boundary between the spring wood and summer wood, and this looks like a blur similar to natural wood. This eliminates the disadvantages of conventional methods of coloring the wood grain, which can be monotonous or have too clear boundaries, making it look like two-color printing, and even with wide grains, it can be applied to natural wood grains. It is now possible to create a similar color change. Furthermore, considering the relative relationship between the color of the spring wood and the color of the summer wood, the summer wood can be made into any dark color, increasing the contrast between them and making the wood grain similar to that of high-quality precious wood. The clear, deep, and beautiful appearance can be identified as the right one. Moreover, even though both the spring and summer wood parts are colored and painted, transparent or semi-transparent paint is used to prevent defects in the wood fabric and changes in color, especially The color of the summer wood part can be seen through the sloping part to some extent, and the beautiful luster of the wood is not lost, making it possible to make the material look natural.

Furthermore, since the wood decorative board of the present invention uses natural wood as it is as a decorative base board, there is no monotonous, repetitive pattern C like printed plywood, and the wood grain is extremely varied. Furthermore, since the decorative original board is textured by processes such as brushing, even if it appears to be the same color tone, complex shading is formed due to the minute unevenness, and furthermore, :Since the coating takes advantage of the sea urchin fabric, the product of the present invention is
It has subtle changes that cannot be obtained with printed plywood or simply painted rough board, and can exhibit a beautiful appearance that closely resembles natural precious wood.

Although the present invention is particularly effective for board grain, it goes without saying that even when applied to straight grain or continuous board, it is possible to obtain a finish that is superior to conventional painted decorative boards.
