Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base material used for buildings, furniture, etc., such as veneer plywood or mortar board, with a natural wood grain pattern that resembles the beautiful, warm and soft wood grain of high quality natural wood. It relates to the applied decorative material.

[0002]

2. Description of the Related Art High-quality wood for construction represented by, for example, Japanese cypress and cedar wood, and high-grade wood for furniture, represented by paulownia wood, teak wood, rosewood wood, teak wood and mahogany. If you try to use it as it is for buildings and furniture, the price will be extremely high.

Therefore, a stripping material (so-called wood board) is produced by thinly peeling from the raw wood in a form in which the beautiful wood grain of these high-grade wood remains clearly, and sticking it on the surface of other wood. The technique of pretending to be using raw wood in a raw form has been widely used.

However, when an attempt is made to obtain a stripping material from a piece of high-grade raw wood in such a manner that the grain of wood is clearly left,
A large amount of wasted parts are generated in the raw wood, which causes a phenomenon that the amount of the stripping material obtained from one raw wood becomes extremely small.

On the other hand, the demand for these high-quality timbers has been increasing along with the growing sense of admiration for these high-grade woods, and therefore, the high-grade raw woods are remarkably decreasing in global scale. Therefore, on the one hand, the cutting of these high-grade logs is minimized to prevent global environmental damage, and on the other hand, in order to cope with the decrease of high-grade logs, the painting and printing methods are used to It is conceivable to draw a pattern simulating the grain of high-quality natural wood on the surface of an appropriate wood, and many methods have already been proposed.

For example, in the method disclosed in Japanese Examined Patent Publication No. 49-46135, first, for example, titanium oxide, carbon black, iron oxide, alkyd resin solution or the like is applied to the surface of a base member made of appropriate wood or the like. An undercoat layer is formed by performing an arbitrary flat coating using the undercoat paint, and a silicon resin paint with a small surface tension is used on the dried undercoat layer, for example, an arbitrary striped pattern forming a wood pattern. Draw.

Thereafter, a transparent, semi-transparent or opaque coating material made of, for example, carbon black, iron oxide, an alkyd resin solution or the like is applied over the entire surface of the silicon resin coating layer having the striped pattern. To form an overcoat layer.

At this time, in the step of forming the overcoat layer, the coating material of the overcoat layer where the silicon resin coating layer formed on the undercoat layer is present is repelled and squeezed around the area where the silicon resin coating is present. Since the action (so-called water repellent action, eye-repelling action) occurs, this action is used to reveal an arbitrary wood grain pattern.

In this case, the striped pattern drawn with the silicone resin coating is drawn in parallel as a plurality of linear stripes having a predetermined width by using a pattern roll or a brush having a structure in which bristles are appropriately thinned. It will be.

Further, Japanese Patent Publication No. 58-44036 (Japanese Patent Laid-Open No.
52-96715), first, an acrylic emulsion-based water-based filler is applied on the surface of a base member made of lauan plywood, and after this coating layer is dry-polished, a light-colored acrylic is used. A lacquer surfacer is applied over the entire surface to form an intermediate coating layer.

Thereafter, acrylic lacquer clear is applied to the surface of the surfacer other than the surface on which the desired pattern such as wood grain or conduit is to be printed, and then a printing agent containing a predetermined amount of a foaming agent is applied. At this time, the printing agent remains in a wet state only on the surfacer surface other than the acrylic lacquer clear coated surface. Then, while the printing agent is in an undried state or a touch-dried state, ordinary ink is used to perform blurring on the desired wood grain, the pattern portion such as the conduit, and the same formulation as the printing agent containing the foaming agent. The skeleton is printed with a matte ink.

Thereafter, a coating film containing an acid component for decomposing the acid-decomposable foaming agent is applied to the entire surface to form a coating film, and further, in a heating environment or room temperature, a pattern portion such as wood grain or a conduit is formed. The other part is dried at the same time. At this time, in the drying process, the surface on which the pattern portion such as wood grain or conduit is printed becomes a fine non-uniform surface due to foaming, and the gloss of the top coating film on the printing surface is reduced. There is a difference in gloss between the smooth surface. As a result, an elegant finish and a three-dimensional appearance of high-quality natural wood can be obtained.

By the way, the method disclosed in Japanese Patent Laid-Open No. 5-115837 is a technique for coloring when forming the surface of a wooden decorative veneer into a floating structure, and particularly for the purpose of forming a wood grain pattern. Although it is not a technique, a floating structure also results in the formation of a wood grain pattern, and is considered to be a prior art of the present invention.

In this method, first, a wood decorative veneer is bonded to the surface of a base member made of an appropriate plywood, and the surface of the decorative veneer is brushed.

At this time, of the spring wood part and the autumn wood part forming the wood grain of the surface of the decorative veneer, the soft spring wood part is deeply cut into a concave shape, and the hard autumn wood part is not cut so much. It becomes a convex shape and becomes a floating structure.

After that, a sealer layer is applied to the surface of the decorative veneer formed in such a floating structure, and a coloring agent is further applied thereon. In this case, the presence of the sealer layer suppresses the penetrating action of the coloring agent, and the contrast of coloring between the spring material portion and the autumn material portion is reduced.

As a result, the wood decorative veneer can be colored while maintaining a soft appearance without "color unevenness".

[0018]

[Problems to be Solved by the Invention]
Since the method disclosed in Japanese Patent Publication No. 49-46135 is suitable for mass production, the drawn stripes of the silicon resin coating are uniform. Moreover, the drawn stripes are expressed as straight lines, and the boundary line between the area where the stripes are drawn and the other area appears in a fairly clear form, and the obtained stripe pattern is It will appear as stiff stripes to the eye. As a result, there is a problem in that the wood grain pattern is sensuously different from the beautiful, deep and soft wood grain of high-grade natural wood.

Further, according to the method of Japanese Patent Publication No. 58-44036, blurring printing is performed to prevent the skeleton portion 7'of the pattern portion such as wood grain or conduit formed by the printing method from appearing as a hard pattern. It becomes necessary, and there arises a problem that the manufacturing process becomes complicated accordingly.

Moreover, since an acid-decomposable foaming agent is used, a special paint such as a paint containing an acid-decomposable foaming agent or a paint containing an acid component that decomposes the acid-decomposable foaming agent is required. A big problem in production will also occur.

Further, the method disclosed in Japanese Patent Laid-Open No. 5-115837 utilizes the difference in hardness between the spring wood part and the autumn wood part of the wooden decorative veneer to make the surface of the wooden decorative veneer uneven. Since the pattern is formed, in order to obtain the beautiful, deep and soft wood grain of high-quality natural wood, it is necessary to make a thin wood of high-quality natural wood on the wood decorative veneer. This is a major drawback of this conventional method because it does not meet the purpose of obtaining the beautiful, deep and soft wood grain of high-grade natural wood without using high-grade natural wood.

The present invention has been made in view of the above circumstances, and its object is to use a paint of a special composition without using any precious high-quality natural wood (so-called wood board). It is not necessary to use it, and moreover, it can be manufactured in a simple process by using most of the coating equipment used in the conventional manufacturing process as it is, and it has a natural wood grain pattern that can significantly reduce the manufacturing cost. It is to provide a decorative material and a manufacturing method thereof.

[0027]

The decorative material having the natural wood grain pattern constructed as described above is formed by first applying the desired natural grain pattern on the surface of the base member which is the basic material of the decorative material used for buildings, furniture and the like. The emulsion paint layer is formed with an emulsion paint that represents one of the constituent colors forming the shade.

Then, an oil color layer is formed on the surface of the emulsion paint layer with an oil color containing a dye and a suitable pigment, the dye representing the other constituent color forming the desired natural pattern shade, and thereafter. The surface of the oil color layer is brushed in the direction in which the natural wood grain pattern is formed by using a plurality of brush members provided over the entire widthwise area of the base member.

As a result, the pigments contained in the oil color layer, to which the dye is attached (including infiltration), are unevenly distributed along the direction of forming the natural wood grain pattern,
By this action, a dark and light stripe pattern of the contained pigment is formed on the emulsion paint layer with the oil color layer, and the presence of the contained pigment of the oil color layer attached on the emulsion paint layer gives a three-dimensional effect.

At this time, the light and shade striped pattern of the contained pigment appears on one side as a light and shade striped pattern of the color represented by the oil color layer, and the color represented by the emulsion paint layer is the shade of the color represented by this oil color layer. It will appear in a mixed state with the striped pattern. That is, although the color represented by the dark and light stripe pattern and the color represented by the emulsion paint layer appear in a composite state, the color represented by the oil color layer also exudes in the emulsion paint layer.

Therefore, the tilted posture of the brush members with respect to the surface of the emulsion paint layer with the oil color layer and / or the inclination angle of the brush members with respect to the direction in which the natural wood grain is formed are determined by the brush member and the base member. If set appropriately in relation to the relative displacement speed, it becomes possible to obtain the desired natural wood grain pattern.

Then, a substantially transparent colorless or colored additional film layer (which is also a protective layer) is formed on the surface of the emulsion paint layer with the oil color layer after the natural wood grain pattern is formed, and the natural color is formed. Fix the grain pattern.

[0033]

EXAMPLES Hereinafter, for example, 3 using an appropriate wood material
A commercially available veneer plywood having a single-layer structure (for example, lauan veneer, cina veneer, etc.) is used as a base member of a decorative material, and the plurality of examples of the decorative material having a natural wood pattern according to the present invention are used. The configuration and the manufacturing method thereof will be described.

FIG. 1 is a schematic perspective view showing a first embodiment of a decorative material having a natural wood grain pattern used for construction, in which the coating layers sequentially formed on the base member are exposed and are easily understood. FIG. 2 is a cross-sectional structure showing a cross-sectional structure taken along the line AA in FIG. In FIG. 1, reference numeral 1 is the base member of the above-mentioned decorative material made of, for example, plywood. If the base member 1 has been previously formed into a flat surface, the surface 1a is finished with a flat rough surface by performing paper hanging using, for example, No. 180 sand paper, with the grain of veneer plywood appearing as it is. ing.

If the base member 1 is bent or uneven, first, for example, an electric plane (planer) is used to cut the surface substantially flat, and then paper 180 is used to make a flat rough surface. Finish. In this case, the direction of paper application does not matter in either case.

Reference numeral 2 denotes, for example, an aqueous emulsion paint layer applied on the surface 1a of the base member 1, which is a natural wood grain pattern to be sought (hereinafter referred to as "target natural wood grain pattern").
(1) is used to form one of the constituent colors, and is applied once or several times by a known application method such as roller application, brush application, or spray application. It is formed as a coating layer having a thickness.

In this case, as a general rule, the thickness of the emulsion paint layer 2 is set to a total thickness capable of covering the surface wood grain of the base member 1, but the surface of the base member 1 has good and beautiful wood grain. In some cases, it is possible to apply the emulsion paint layer 2 thinly so that the grain and color of the base member 1 can be utilized. When the emulsion coating layer 2 is formed by coating several times, the coating film applied to the uppermost layer should be applied in such a state that the coating film can flatten the surface of the emulsion coating layer 2. preferable.

After the emulsion paint layer 2 is dried, the surface 2a is subjected to a paper hanging operation using, for example, No. 280 sand paper, in the direction of forming a desired natural grain pattern (hereinafter referred to as grain forming direction). Carry out in the direction along to finish a flat surface (smooth surface). As the paint for forming the emulsion paint layer 2, for example, the following paints are preferable.

[First Example] Manufacturer Rock Paint Co., Ltd. Product No. 032-D100 Product name Vinyloc acrylic External white standard JIS K 5663 Class 1 composition Pigment content 44% (weight percentage.
Same below) Acrylic emulsion paint resin 17% Water 35% Additives 4%

[Second example] Manufacturer manufactured by Kansai Paint Co., Ltd. Product name VINYDELUX 500 standard JIS K 5663 -1987 Synthetic resin emulsion paint 2 types (for internal use) Composition coloring / extensive pigment 42% Acrylic resin emulsion 10% Additive 7% Water supply 41%

[Third example] Manufacturer manufactured by Union Paint Co., Ltd. Product No. 14-21 Product name Wood surfacer White Composition Titanium White 20.0% Body pigment 13.5% Alkyd resin 11.0% Nitrified cotton 6.0% Aromatic hydrocarbon solvent 26.5% Ester solvent 6.0% Ketone solvent 5.0% Alcohol solvent 5.0% Glycol solvent 2.0%

Reference numeral 3 is a first oil color layer applied on the surface 2a of the emulsion paint layer 2 and, in combination with one of the constituent colors of the emulsion paint layer 2, forms the desired natural wood grain shade. It is formed as a coating layer of an aqueous solution containing a powdery substance such as a pigment showing the constituent color.

In this case, the pigment is composed of a mixture of the color composition and necessary additives, and the mixture is dissolved by an appropriate amount of water to form an aqueous solution, which is then placed on the emulsion paint layer 2. Is applied to form the first oil color layer 3, and the concentration of the aqueous solution and the application thickness of the first oil color layer 3 at this time are, for example, this layer 3
Is formed on the emulsion paint layer 2,
The thickness and coating thickness are set such that the other constituent color of the first oil color layer 3 covers one constituent color of the emulsion paint layer 2.

By the way, the color composition for expressing the other constituent color of the pigment and other powdery materials is selected according to the intended color tone of the natural wood pattern. In addition, additives in the powder form should be mixed in order to give the necessary darkness to the shade represented by the combination of color compositions, or to give a natural feeling with a three-dimensional effect. become.

For example, when the finish is rosewood, it is preferable to use a pigment having the following color composition and additive composition.

[First example] Color composition Brown 2.21% 5g (weight ratio) Red 11.06% 25g (weight ratio) Green 25.66% 58g (weight ratio) Blue 21.23% 48g (weight ratio) Additive composition Pearl 30.97% 70g ( Weight ratio) Gold powder 6.63% 15g (weight ratio) Silver powder 2.21% 5g (weight ratio)

[Second Example] Color composition Brown 2.84% 5g (weight ratio) Red 14.2% 25g (weight ratio) Green 32.95% 58g (weight ratio) Blue 27.27% 48g (weight ratio) Additive composition Pearl 11.36% 20g ( Weight ratio) Gold powder 8.52% 15g (weight ratio) Silver powder 2.84% 5g (weight ratio)

In the first embodiment, these [first examples]
In addition, the color compositions in the table of [Second Example] are generally commercially available, for example, "BROWN 416", "RED5B", and "GR" manufactured by Orient Chemical Industry Co., Ltd.
EEN BG "and" BLUEBOS "are used.

As for the additive composition of pearl, gold powder and silver powder, it is preferable to use those which are generally commercially available, for example, those having the following compositions.

Pearl Nihon Koken Kogyo Co., Ltd. Titanium oxide powder about 28% Mica powder about 72%

Gold powder (Akaguchi) made by Nakajima Metal Foil & Powder Co., Ltd. Cu powder 86.4% or more Zn powder 12.8% or more Fe powder 0.2% or less Pb powder Trace level Sn powder Trace level

Gold powder (blue mouth) Made by Nakajima Metal Foil & Powder Co., Ltd. Cu powder 75.6% powder or more Zn powder 23.6% or more Fe powder 0.2% or less Pb powder Trace level Sn powder Trace level

Silver powder Nakajima Metal Foil & Powder Co., Ltd. Al powder 98.6% Cu powder 0.2% Fe powder 0.9% Si powder 0.3%

In the case of these two examples, the other shade of the natural wood pattern is produced by the combination of the color compositions in each table, and the hue (color tone) by the color composition is obtained by the additive composition of gold powder and silver powder. The darkness is emphasized without changing the color, and the additive composition of pearls gives a natural three-dimensional feeling without changing the hue of the color composition.

In this example, gold powder and silver powder are used as additives for emphasizing the darkness. This is because silver powder, which has a relatively light weight when the pigment is made into an aqueous solution, is the first oil color. This is to disperse the gold powder having a relatively heavy weight in the upper region of the aqueous solution and to disperse the relatively heavy gold powder in the lower region of the aqueous solution so that the dispersion in the aqueous solution becomes uniform as a whole.

Reference numeral 4 is a fine uneven surface formed on the surfaces of the emulsion paint layer 2 and the first oil color layer 3 in order to obtain the desired underlying pattern of the natural wood pattern, and the first oil color layer 3 is in a wet state. At some time, the first oil color layer 3 may be held, for example, by using an appropriate fine unevenness forming member (not shown).
It will be formed by lightly rubbing from above.

For example, while lightly rubbing the fine concavo-convex forming member in small grain areas in the grain forming direction with a relatively short stroke,
By moving in the wood grain forming direction sequentially and over the entire area, a large number of minute rubbing lines are formed on the surfaces of the first oil color layer 3 and the emulsion paint layer 2, and
A large number of these minute rubbing lines are formed so as to face the grain forming direction as a whole.

In this case, it is preferable to use, for example, a lump of steel wool or a lump of sandpaper strip that is cut into a thread shape as the fine concavo-convex forming member.
The rubbing by the fine concavo-convex forming member may be, for example, reciprocal rubbing in the grain forming direction, or rubbing in only one direction in the grain forming direction.

Which method is adopted will be determined depending on the intended state of the natural wood grain pattern or how to represent it. As a result, a large number of minute rubbing lines are intermittently formed on the surface of the emulsion paint layer 2 via the first oil color layer 3, and these rubbing lines form a shape / structure that generally faces the grain formation direction. That is, a large number of minute uneven portions are completed.

Then, when the first oil color layer 3 is semi-dried or the water in the first oil color layer 3 is evaporated, the surface of each of the large number of minute irregularities is irregularly formed. 1 The pigment of the oil color layer 3 is attached.

Therefore, in the state where the minute uneven surface 4 is formed, due to the unevenness of the minute uneven portions formed on the surface of the emulsion paint layer 2 and the irregularity of the pigment adhesion amount of the first oil color layer 3, One of the constituent colors forming one of the shades of the natural wood pattern and the other constituent color are mixed in a state of having a natural feeling with a three-dimensional effect.

Reference numeral 5 designates a fine uneven surface 4 cleaned by an appropriate method.
A second oil color layer applied on top of the first oil color layer
It is formed as a coating layer of an aqueous solution containing a pigment having the same composition as the pigment of the oil color layer 3. In this case, the concentration of the aqueous solution that becomes the second oil color layer 5 and the thickness of the second oil color layer 5 are determined depending on the desired state of the natural wood grain pattern or how to express it. .

Reference numeral 6 denotes a final wood grain pattern surface formed on the second oil color layer 5, and when the second oil color layer 5 is in a wet state, the second oil color layer 5 is appropriately brushed. From above, the second oil color layer 5 (base member 1
And also the emulsion paint layer 2) and by lightly printing once or several times in the grain forming direction.

In this case, the brush means has a wood grain forming brush means 43 having a structure described later, for example, a plurality of independent brush means 44, 47, 50 which are independent from each other in several rows (for example, three rows) along the grain forming direction. And a plurality of unit brush members 46a to 46d, 49a to 49c, 52a to 52c are arranged in the direction (width direction) orthogonal to the grain forming direction as the brush means of the structure. The hardness of the bristles provided on the brush member is set to various hardnesses.

Furthermore, the angle of the arrangement position of the unit brush members with respect to the grain forming direction, the inclination of the bristles with respect to the surface of the second oil color layer 5, etc. are appropriately set to obtain the desired natural grain pattern. To do so. The work of forming the final woodgrain pattern 6 will be described in detail in the section of the manufacturing method described later.

After the final wood grain pattern surface 6 is formed and dried, the additional film layers 7 to 11 are formed as described below. Reference numeral 7 is a first sanding sealer layer formed on the dried final wood grain surface 6 and is formed as a relatively soft colorless and transparent coating layer. This layer 7 will be formed as an intermediate coat layer for improving the adhesion of the overcoat layer applied on the first sanding sealer layer 7, for example, by spraying once or several times. .

In this case, the first sanding sealer layer 7
Will be applied to the final wood grain pattern surface 6 in a state in which a paint having a predetermined composition is diluted with, for example, a lacquer thinner so as to be easily applied. Also, the number of times of coating (film thickness)
Is determined according to the user's desire or preference for the intended finished surface of the decorative material.

That is, when the user requests a finished surface having a more natural appearance, it is applied once, and when a mirror-finished surface is requested, it is applied several times. To do.

After the first sanding sealer layer 7 is dried, the surface 7a is subjected to a paper hanging operation using, for example, No. 320 sand paper, for example, in the direction along the grain forming direction to finish it into a flat surface. In addition, as a coating material for forming the first sanding sealer layer 7,
For example, the following compositions are preferable.

Product No. 14-02 manufactured by Union Paint Co., Ltd. Product name Sanding Sealer

Composition Nitrified cotton 13% Alkyd resin 15% Abrasive 3% Plasticizer 3% Aromatic hydrocarbon solvent 36% Ester solvent 22% Alcohol solvent 5% Glycol solvent 3%

Further, as the lacquer thinner, one having the following composition is preferable.

[First Example] Rock Paint Co., Ltd. Product No. 016-o123 Product name Lacquer thinner Standard JIS K 5538 Composition ester solvent 29% by weight Aromatic hydrocarbon solvent 63% by weight Alcohol solvent 8% by weight

[Second Example] Kansai Paint Co., Ltd. Product number Selva 151 Product name Lacquer thinner composition Ester solvent 29% by weight Alcohol solvent 8% by weight Hydrocarbon solvent 63% by weight

Reference numeral 8 is a wood sealer layer formed on the first sanding sealer layer 7 after the paper application work, and is formed as a colorless and transparent coating film layer having a hardness that sandpaper cannot be applied. This layer 8 plays the role of emphasizing the final wood grain pattern surface 6 while providing the shade from the underlying emulsion paint layer 2 to the first sanding sealer layer 7.

The wood sealer layer 8 is formed by diluting a paint having a predetermined composition with an appropriate solvent and applying the paint once by, for example, a spraying method. As the paint, the following compositions are preferable.

Union Paint Co., Ltd. Product No. 14-12 Product name Wood sealer Composition Nitrified cotton 10.5% Alkyd resin 21.5% Plasticizer 2.0% Aromatic hydrocarbon solvent 38.5% Ester solvent 17.0% Glycol solvent 8.5% Alcohol solvent 2.0 %

Reference numeral 9 denotes a transparent color adjusting layer (coloring layer) formed on the dried wood sealer layer 8 for finally adjusting the color tone of the surface of the decorative material. The color adjusting layer 9 is formed by applying a paint having the following composition by mixing a thinner and a wood sealer.

Reference numeral 40 denotes a brushing device installed in the area of the next step of the uneven surface forming apparatus 30, which is arranged in the area 41 of the next step of the delivery roller device 20 on the belt conveyor pedestal 31 of the uneven surface forming apparatus 30. ing.

This brushing device 40 has a second oil color applying means 42 having the same structure as the above-mentioned first oil color applying means 32 in the front area, and a grain forming brush means 43 in the next process area. It is configured as a device.

In this case, the second oil color applying means 42
Is provided with a supply container 42a and a coating roller 42b, and is configured to be supported by the belt conveyor pedestal 31 by a suitable supporting means known per se.

On the other hand, the wood grain forming brush means 43 is constituted by means of the first to third rows of independent brush means 44, 47, 50 which are arranged in series at a predetermined interval (for example, 400 cm). ing.

In this case, the independent brush means 44 in the first row is
For example, five unit brush members 46a to 46e supported by an appropriate support member 45 are arranged to extend over the width of the belt conveyor pedestal 31.

The independent brush means 47 in the second row is composed of three unit brush members 4 supported by appropriate supporting members 48.

The inclinations of a to 52c with respect to the wood grain forming direction in the horizontal plane, and the vertical postures of the emulsion paint layer 2 with respect to the surface 2a are also appropriately set so as to obtain a desired natural wood grain pattern. There is.

For example, when the inclination of one unit brush member 46a or the like with respect to the grain forming direction in the horizontal plane is changed, the thickness and softness of the flocked delicately changes.

On the other hand, for example, one unit brush member 46a or the like is attached to the surface 2a of the emulsion paint layer 2 as shown in FIG.
On the other hand, when the posture is set to be upright, the striped pattern becomes thick and blurred, and when the posture is set to lie on the surface 2a of the emulsion paint layer 2 as shown in FIG. The striped pattern becomes clear. Therefore, in consideration of these situations, each unit brush member 46
By appropriately setting the inclination and posture of a, the target natural wood grain pattern can be obtained.

In the illustrated embodiment, the uneven surface forming device 3 is used.
Brushing device 40 on pedestal 31 of belt conveyor 0
The belt conveyor pedestal 3
It is also possible to configure the area 41 of the next step of the delivery roller device 20 on 1 as an independently separated belt conveyor pedestal.

By the way, the manufacturing work of the decorative materials 1 to 11 is as follows.
After the emulsion paint layer 2 is formed on the surface 1a of the base member 1 formed in predetermined vertical and horizontal dimensions (standard size) by using a method or an apparatus known per se, after the emulsion paint layer 2 is dried. The base member 1 of FIG. 3 is delivered in a state in which its longitudinal direction coincides with the direction from right to left in FIG.
It starts from placing on top.

The base member 1 with the emulsion paint layer 2 placed on the delivery roller device 20 in this way is
It is moved to the uneven surface forming device 30 for forming the fine uneven surface 4 by the carrying roller means 22, and is further carried at a predetermined speed in the grain forming direction by the belt conveyor pedestal 31 of the uneven surface forming device 30.

At this time, the pigment or colored powdery aqueous solution of the first oil color layer 3 injected into the supply container 32a is nonuniformly dropped onto the emulsion coating layer 2 via the coating roller 32b to form an emulsion. The irregular first dark and light first oil color layer 3 is formed (applied) on the paint layer 2.

Thereafter, as the base member 1 moves, the first
The fine unevenness forming member (mass of sandpaper strips) 34 of the fine unevenness forming means 33 comes into contact with the emulsion paint layer 2 in a state of being infiltrated by the pigment aqueous solution of the oil color layer 3, and the emulsion paint layer 2 is covered with a large number of fine particles. A rubbing line will be formed.

At this time, the contact pressure of the fine unevenness forming member 34 to the emulsion paint layer 2 is changed through the holding box 33a by rotating the drive shaft 33c of the fine unevenness forming means 33 irregularly in the reciprocating direction. Since it is controlled, the large number of fine irregularities formed on the emulsion paint layer 2 become irregular and become the fine irregularity surface 4.

At the same time, one constituent color of the emulsion paint layer 2 and the other constituent color of the first oil color layer 3 are intermingled in the grain formation direction and the width direction to form a complicated color.

As a result, the surface of the emulsion paint layer 2 after being coated with the aqueous pigment solution forming the first oil color layer 3 becomes a finished surface having a natural feeling closer to the desired natural wood grain pattern. Then, the base member 1 with the emulsion paint layer 2 on which the fine uneven surface 4 is formed continues to move by the belt conveyor pedestal 31.

Now, when the base member 1 moves, in the process, as in the case of the first oil color applying means 32 described above, the supply container 4 of the second oil color applying means 42.
The pigment aqueous solution of the second oil color layer 5 is nonuniformly dropped from the inside of 2a onto the emulsion layer 2 after the formation of the fine uneven surface 4 through the coating roller 42b, and the emulsion layer 2 is irregularly shaded. 2 The oil color layer 5 is formed (applied).

Then, subsequently, the grain forming brush means 4
3 rows of independent brush means 44 to 50 brush the entire surface of the fine concavo-convex surface 4 from above the second oil color layer 5.

First, the unit brush members 46a to 46e of the independent brush means 44 of the first row sweep the surface of the fine uneven surface 4 softly, and then the unit brush members 49a to 49c of the independent brush means 47 of the second row are For example, in a state where the boundaries between the unit brush members 46a to 46e in the first row are eliminated, the fine uneven surface 4 is swept softly in the grain forming direction, and further, the third
The unit brush members 52a to 52c of the independent brush means 50 in the row are swept gently above the unit brush members 49a to 49c in the second row, for example, to eliminate the boundaries, and finally the surface of the fine uneven surface 4 is formed. A synthetic imprint pattern (striped pattern) composed of irregular dark and light patterns of the second oil color layer 5 is formed thereon.

The brush pattern thus formed is
The pattern has a three-dimensional effect that is very similar to the natural wood grain, and this is the final wood grain pattern surface 6. As mentioned above,
The unit brush members 46a to 46e, 4 with respect to the grain formation direction
9a-49c, 52a-52c array position angle and the second
The inclination or the like of the flocked with respect to the surface of the oil color layer 5 is appropriately set by conducting experiments or tests in advance so that the desired natural wood grain pattern can be obtained.

After the final grain pattern surface 6 is in a dry state, the additional film layers 7 to 11 are formed thereon. In this case, the work of forming each coating film forming the additional film layers 7 to 11 while moving the base member 1 after the final wood grain pattern surface 6 is formed in the wood grain forming direction by a conveying means such as a belt conveyor. Then, the cleaning work, the forced drying work and the like are appropriately performed to form the intended decorative material.

However, since the forming work and the like relating to the additional film layers 7 to 11 are carried out by a known method by means known per se, detailed description thereof will be omitted.

The second embodiment of the present invention is the same as the first embodiment described above except that the first oil color applying means 32 (or
Second oil color applying means 42), fine unevenness forming means 3
3. The cleaning means 35 is removed.

That is, the brushing operation by the wood grain forming brush means 43 is performed directly on the emulsion paint layer 2 on which the first or second oil color layer 3 or 5 is applied. The desired natural wood grain pattern can be obtained although the natural feeling is lower than that of the first embodiment.

Although the illustrated embodiment has been described above, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention. For example, the additional film layer after the final wood grain surface 6 is formed does not need to have a five-layer structure as in the first embodiment, and may be appropriately formed depending on the required degree of the decorative materials 1 to 11. It can be formed into a layer structure.

Also, regarding the grain forming brush means 43,
It is also possible to configure with independent brush means other than three rows.
Further, the final grain pattern surface 6 can be formed by intermittently reciprocating the grain forming brush means 43 in the direction opposite to the grain forming direction with respect to the transported base member 1.

Further, the base member 1 is not limited to the veneer material, but may be a single wood (single plate), concrete or mortar block, a synthetic resin material, a metal material (for example, aluminum, stainless steel) or the like. Further, the material form can be widely applied to a plate material, a square material, a draw board, an empty material, and the like. Furthermore, for the target surface forming the natural wood pattern, a flat surface, a curved surface,
It can be a cylindrical surface, a spherical surface, an aspherical surface, or the like.

[0136]

As described above, when the present invention is used, precious high-quality natural wood is not used at all, and it is not necessary to use a paint having a special composition, and it is used in the conventional manufacturing process. It is possible to manufacture almost all of the applied coating devices as they are in an additional process, and it is possible to realize a decorative material with a natural wood grain pattern and its manufacturing method that can significantly reduce the manufacturing cost. Moreover, it will be possible to prevent global destruction of nature due to overcutting.

For example, in the case of an interior material or a furniture material in which a peeling plate (about 0.3 mm) as a so-called wood board with the wood grain of rosewood material left is stuck on an appropriate plywood,
It is a commercial price of 30,000 yen to 100,000 yen / m ² , and even a popular product with no joints is about 36,000 yen. / M ² ) is used, the final price including the coating cost is as low as 6000 yen to 7,000 yen / m ² and the same appearance and strength as the stripping plate product can be obtained, and Even if you use China veneer (1000 yen / m ² ), you only have to add the difference from Lauan veneer.
