Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variety of building materials, such as veneer plywood, which are used for building and furniture with a natural wood grain pattern that resembles the warm and soft feeling of high quality natural wood. Natural wood grain pattern on materials that liquid does not soak into, such as wood, mortar, cement (concrete), gypsum and board, and materials that do not soak into liquid, such as metal, plastic and glass "Natural wood grain pattern forming device" for obtaining decorative materials
It is about.

[0002]

2. Description of the Related Art For example, high-grade wood represented by cypress and cedar wood, and high-grade wood for furniture represented by paulownia wood and mahogany, are used for buildings and furniture in a raw state. If so, the price will be extremely high. Therefore, if the beautiful wood grain of these high-grade wood is thinly peeled off from the raw wood in a form that clearly remains, and it is attached to the surface of other wood, whether the high-grade wood is still used in the raw form. The method of pretending to be like this has been widely used from the past.

[0003] However, in order to obtain a stripping material in such a manner that the grain is clearly left from a single high-quality log like this,
A large amount of useless portions are generated in the raw wood, and a phenomenon occurs in which the amount of the stripping material obtained from one raw wood becomes extremely small. On the other hand, as the desire for these high quality timbers has increased, the demand for these high quality timbers has continued to increase, so that these high quality timbers have been remarkably decreasing on a global scale. Therefore, on the one hand, to prevent environmental damage on a global scale by minimizing the felling of these high-grade raw trees, and on the other hand, in order to cope with the decrease of high-grade raw trees, use painting methods and printing methods, It is conceivable to draw a pattern simulating the grain of high-grade natural wood on the surface of another suitable wood, and many methods have already been provided for that purpose.

The inventor of the present application invented a decorative material showing a high-grade natural wood grain pattern very similar to the case of using high-grade natural wood and a method for producing the same, and applied for a patent on July 30, 1993. The application was filed as Japanese Patent Application No. 5-208453 (hereinafter, the invention related to this application is referred to as "prior invention"). The formation of the natural wood grain pattern in Invention 1 of the prior application is performed as follows.

That is, first, an emulsion layer is formed on the surface of a base material of a decorative material used for construction, furniture, etc., with a coating agent representing one of the constituent colors forming a desired natural wood grain pattern shade. On the surface of this emulsion layer, an oil color layer is formed with an oil color containing a dye and a suitable pigment, the dye representing the other constituent color forming the desired natural wood grain shade, and then the substrate. Using a plurality of brush members provided over the widthwise area of the material, the surface of the oil color layer is brushed in the direction in which the natural wood grain pattern is formed to reveal the natural wood grain pattern.

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 layer with the oil color layer, and the presence of the contained pigment of the oil color layer attached on the emulsion layer causes a three-dimensional effect. At this time, the light and shade stripe pattern of the contained pigment appears on one side as a light and shade stripe pattern of the color represented by the oil color layer, and the color represented by the emulsion layer is mixed with the light and shade stripe pattern of the color represented by this oil color layer. It will appear in the state.

That is, the color represented by the dark and light stripe pattern and the color represented by the emulsion layer appear in a composite state. In addition, the color represented by the oil color layer may seep into the emulsion layer. In this case, the tilted posture of the plurality of brush members with respect to the surface of the emulsion layer with the oil color layer and / or the inclination angle of the plurality of brush members with respect to the direction in which the natural wood grain is formed is determined by the relative displacement speed between the brush member and the base material. Set it appropriately in relation to and form 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 layer with the oil color layer after the natural wood grain pattern is formed.
Is formed to fix this natural grain pattern. By the way, since the decorative material for construction is used for a long period of time in the environment exposed to the living space, it was exposed to sunlight or illuminating light when manufacturing the decorative material. At times, it is necessary to take into consideration that discoloration or fading that does not spoil the appearance of the wood grain pattern will occur, and it is necessary to devise measures for that.

On the basis of this consideration, the inventor and applicant of the present invention invented a decorative material showing a high-grade natural wood grain pattern very similar to the case of using high-grade natural wood, and a method for producing the same.
The application was filed as Japanese Patent Application No. 6-337492 filed on Dec. 28, 1995 (hereinafter referred to as "prior invention 2"). In the prior invention 2, the following steps 1 to 7 are performed to form a natural wood grain pattern. That is, architecture,
A decorative material with a natural wood grain pattern used for furniture and the like is first prepared by using sandpaper to finish the surface of the base member, which is the base portion of the decorative material used for architecture, furniture, etc., into a flat and rough surface. Carry out work (step 1).

Next, in order to form a basic color tone coating film on the surface of the substrate member formed as a flat and rough surface, a desired natural wood grain pattern that closely resembles the wood grain of high-grade natural wood is formed in accordance with the desired color. After applying the basic color paint obtained by mixing the main agent liquid and the toning liquid, the surface is covered with paper using sandpaper (step 2). Next, in order to form a desired natural wood grain pattern paint layer, a composite pigment of a desired color obtained by mixing black, red, and yellow pigments as needed was used as a rough coating of the basic color tone coating layer. Apply evenly on the surface (step 3).

Next, in order to form a desired natural wood grain pattern, the wood grain pattern putting paint layer is rubbed in a predetermined direction with a hand pad before the wood grain pattern putting paint layer is dried. 1 A rubbing line is formed (step 4). Further, a second rubbing line is formed by rubbing the surface on which the first rubbing line is formed in a predetermined direction with a brush member,
With these two types of rubbing lines, a large number of fine concave-convex rubbing lines are formed as a whole in a predetermined direction (step 5). Thereafter, for example, a drying operation is performed at room temperature for a predetermined time (step 6). Then, finally, in order to form the surface finishing layer, the above steps 1 to 6 are performed to form a natural wood grain coating on the surface of the decorative material, and then the surface is substantially transparent and colorless. Alternatively, a colored paint layer is formed (step 7).

Accordingly, the prior invention 2 does not use precious high-grade natural wood at all by performing the above steps 1 to 7 in sequence, and further, it is not necessary to use a paint having a special composition. Moreover, it is possible to obtain a decorative material having a natural wood grain pattern for use in construction and furniture, which can prevent discoloration or fading due to sunlight or illumination light while significantly reducing the manufacturing cost. In addition, among the many steps for obtaining a decorative material having a natural wood grain pattern (details will be described later), a coating film forming step for forming a coating film for putting a wood grain pattern, and the applied wood grain There has been a demand for the appearance of a "natural grain pattern forming device" that performs two steps, namely, a rubbing line forming step for applying a rubbing line to a pattern-containing coating film.

This is for removing foreign substances and the like attached to the brush tip portion 78 and the second brush tip portion 80 ". In order to obtain a decorative material by using the "natural grain pattern forming apparatus" according to the first embodiment of the present invention configured as described above, the following steps should be taken before the coating film is formed by the coating film forming means 68. Such pretreatment is necessary.

[I] Formation of "Basic Constituent Layer" Using Pigment Paint Regarding the formation of the "basic constituent layer", a case of forming it on a base member (including plywood) made of wood will be described as a typical example. FIG. 5 is a perspective view schematically showing a configuration of a first example of “a decorative material having a natural wood grain pattern” manufactured by using the natural wood grain pattern forming device 88 according to the first embodiment of the present invention. In order to clearly show the layer structure, the coating layers formed on the base member are sequentially exposed.

FIG. 6 is a sectional view showing the structure of a section taken along line AA in FIG. In this example, first
A base member 1 made of an appropriate wood material is prepared, and as the base member 1, for example, a veneer plywood (for example, ""Rawanveneer","Sinaveneer", etc.) will be selected [step S1]. In this case, for example, a paper hanging operation (sander) using, for example, No. 180 sandpaper is performed on the surface 1a of the base member 1 (the surface on the side that becomes the surface of the decorative material. Finish with a flat, rough surface that allows the grain of the material to appear as it is.

However, when the surface 1a is previously flattened, the paper-hanging operation may be omitted. If the surface 1a of the base member 1 has a bend or unevenness, the surface 1a is first cut almost flat with, for example, an electric plane (canna), and then a paper hanging operation using a No. 180 sandpaper is performed. To make a flat rough surface. In any case, the direction of paper hanging in the paper hanging operation does not matter.

Next, as shown in FIGS. 6 and 7, on the surface 1a of the base member 1, a predetermined paint prepared according to the color of the desired (desired) natural wood grain pattern M is applied. For example, a spraying method known per se is applied several times (for example, twice) to form the polyurethane surfacer layer 2 which is the basic color tone coating layer of the "basic constituent layer" [Step S
2].

In the illustrated example, the paint used for forming the polyurethane surfacer layer 2 is prepared by mixing one or a plurality of A liquids selected from the following A liquid group to prepare a main liquid. A toning solution selected from the following toning solution group is blended to prepare a basic toning mixed solution (a plurality of solutions A + toning solution) according to the type of the natural woodgrain pattern M, and this mixed solution is prepared. The following liquid B (a type of curing agent) is added at a mixing ratio of 4: 1 with the basic color mixture.

The liquid is diluted by adding a necessary amount (for example, 10%) of an appropriate diluting liquid such as urethane thinner according to the material of the base member and the temperature at that time. If it is a suitable material, it should be diluted (prepared) with a hard material.

Other paints can be used as the paint for the polyurethane surfacer layer 2. For example, acrylic lacquer or phthalic paint (oil paint) can be used. After the polyurethane surfacer layer 2 is applied in this way, on the coating layer 2, in the illustrated example, sandpaper No. 180 to
A paper hanging operation is performed by a sander using No. 240 to form a predetermined paper rough surface 3 [Step S3]. Then, after the work of forming the predetermined rough surface 3 of the paper is finished, the predetermined grain-finishing paint is evenly applied on the rough surface 3 of the paper to form the grain-finishing coating layer 4 as a grain-patterned coating film, which will be described later. As described above, it is formed by the natural grain pattern forming device 88 [Step S
4].

The wood graining paint used for forming the wood grain coating film layer 4 is a "composite pigment" for realizing the intended color tone of the natural wood grain pattern M and a "water-based" which plays the role of an adhesive (glue). Sheila will be mixed and made. In this case, the "composite pigment" is prepared by mixing 2 to 3 kinds of "black", "red", and "yellow" pigments at a predetermined ratio, and the mixed pigment is mixed with an AS aqueous sealer (or, It is converted into a "composite pigment" composed of a powder of small particles by crushing in the mixing process with an aqueous clear sealer.

The "water-based sealer" is originally used as an adhesive or an undercoating agent for a base material or base layer, and is diluted with an appropriate amount of water.
In this case, a material such as a wood material, a mortar material, a cement material, a board material, or the like into which a liquid permeates is selected as the base material. Below, "composite pigment" used for the wood grain coating layer 4
Although specific examples of "water-based sealer" will be described, the kind of color tone of [composite pigment], manufacturer, etc., and components, manufacturer, etc. of [water-based sealer] are not limited to these specific examples.

[0070]

[Table 2]

[0071]

In the coating process performed using the "composite pigment" and the "aqueous sealer" as described above, first, the coating material P selected as described above is put into the solution tank 69 of the coating film forming means 68 and loaded. The pre-processed base member 1 is placed on the plate 61a, and the loading plate 61a is lifted upward to move the moving frame 6
When 4 is moved in the direction of arrow a, the coating brush 70 does not rotate until the brush 70c of the coating brush 70 comes into contact with the edge portion of the base member 1, and when the brush 70c comes into contact with the brush 70c, the coating material P is crushed. Application is started on the edge of the member 1.

Further, when the moving frame 64 is moved in the direction of the arrow a, the entire coating brush 70 is rotated in the direction of the arrow b while being crushed by the upper surface of the base member 1, and further brushed by the brush 70c soaked with the paint P. The paint P is applied to the upper surface of the base member 1. The coating speed of the paint P, that is, the moving speed of the moving frame 64, which has been applied in this manner, has been applied in the distance from the application by the brush 70c to the formation of the first rubbing line by the first hand pad 73 in the next stage. It is necessary to set the value such that the time period in which the coating material P does not completely dry elapses.

If the coating speed is too fast, the first rubbing line by the first hand pad 73 in the next stage will not be formed because it is a liquid paint that has not dried, and if the coating speed is too slow, it will be completely lost. It becomes dry and the first rubbing line cannot be formed. Therefore, it is desirable that the application speed is such that it is in a semi-dry state when the applied coating material reaches the first hand pad 73. When the coating film in such a semi-dried state reaches the first hand pad 73, the first hand pad 73
The paint is rubbed with the moving frame 64, and the moving frame 64 is further moved in the direction of the arrow a.
By this, the paint is rubbed again, and the first rub line is formed by the combined action with the second hand pad 75 described later.

For the first rubbing line, each factor such as size, shape, hardness, contact pressure, and number of uses of the first handpad 73 and the second handpad 75 should be appropriately set as described above. It is possible to obtain a desired first rubbing line shape. In addition, the contact pressure in each of the first hand pad 73 and the second hand pad 75 is
The contact pressure can be increased by adjusting the loading plate 61a to a higher position by making some adjustments depending on the position above a.

Since the contact pressure between the coating brush 70 and the upper surface of the base member 1 is also changed by setting the loading plate 61a higher as described above, the dimensions of each part are adjusted so that the pressures of the two become appropriate. It is necessary to set.
In addition, the pressing plates 74 and 7 supporting the hand pads 73 and 75
The position of 6 may be changed. And
Further, when the moving frame 64 is moved in the direction of the arrow a, the rubbing line formed by the first hand pad 73 is further rubbed by the second hand pad 75 to form a composite by the first hand pad 73 and the second hand pad 75. The first rubbing line is formed.

Further, when the moving frame 64 is moved in the direction of the arrow a, the first rubbing line forming means 72 forms the first rubbing line.
Fine irregularities are formed by the first brush tip portion 78 on the surface of the relatively large irregular portion of the rubbing line, and when the moving frame 64 is moved in the direction of the arrow a, the second brush tip portion 80 compositely forms. Fine irregularities are formed, and the second rubbing line is formed by the second rubbing line forming means 77. The rubbing line formed by the second rubbing line and the first rubbing line in combination is, as described above, the size, shape, hardness, contact pressure, and contact force of the first hand pad 73 and the second hand pad 75, respectively. Each factor such as the number of uses, the first brush tip portion 78 and the second brush tip portion 8
0 hair length, hardness, density, contact pressure, number of installations (number of uses)
The desired rubbing line shape can be obtained by appropriately setting factors such as the degree of inclination (tilt) with respect to the surface of the wood grain coating and the angle between the line of hair and the rubbing direction (predetermined direction). be able to.

When the application and the rubbing line formation are completed on the upper surface of the pretreated base member 1 in this manner, the coating film forming means 68 is lowered by lowering the loading plate 61a (or by raising the moving frame 64). First rubbing line forming means 7
2. The base member 1 is separated from the formation portion of the second rubbing line forming means 77, and the coating and rubbing line forming steps are completed. Then, when the moving frame 64 is moved in the direction opposite to the arrow a, the first brush tip portion 78 and the second brush tip portion 80 forming the second rubbing line forming means 77 are in an inverted state at the artificial grass 82 portion. The water and foreign substances are removed by being handled, and the first brush tip portion 78 in the inverted state is moved by moving it further in the direction opposite to the arrow a from the normal intended position and then in the direction of the arrow a. Therefore, the second brush tip portion 80 is changed to the normal state at the artificial grass 82 so that the next coating step and rubbing step can be performed without any trouble.

Therefore, the first and second rubbing lines are composed of a large number of fine fine uneven rubbing lines that are oriented in a predetermined direction as a whole, and thus the first rubbing line pattern and the second rubbing line pattern are varied. Desired natural wood grain pattern M by synthesizing instead of
It is possible to form an uneven rubbing line that realizes After the work of forming the uneven rubbing line is completed, for example, at room temperature.
A desired natural wood grain pattern M is formed by performing a drying operation for about 5 to 30 minutes.

When the natural wood grain pattern M is formed on the back surface of the base member which is made of glass or transparent plastic material and at least the back surface of which is a smooth surface, first the lower surface of the wood grain coating layer 4 is formed. The first rubbing line is formed on the first rubbing line, and then the second rubbing line is formed on the lower side surface of the first rubbing line surface. Will be formed. Further, the time of the above-mentioned drying work is changed depending on the environmental temperature at that time.

As described above, the polyurethane surfacer layer 2, the paper rough surface 3, the wood grain coating layer 4, and the natural wood grain on the wood grain coating layer 4 formed in the processes of [Step S2] to [Step S4]. With the pattern M, the “basic constituent layers” 2 to 4 · M when the pigment paint is used are constituted. In the above description, the surface 1a of the base member 1 is
Is made to be a flat rough surface, or the paper rough surface 3 is formed.
It is additionally noted that this is not an essential condition of the present invention. Next, the surface finish formed on the “basic constituent layers” 2 to 4 · M using the pigment paint will be described. [II] Formation of "Surface Finish Layer of Decorative Material" by Clear Lacquer The second example of the decorative material manufactured by the natural grain pattern forming device according to the first embodiment of the present invention is made of wood material. In the case of forming a "surface finish layer of a cosmetic material" (hereinafter also referred to as "surface finish addition film layer") by clear lacquer on the surface of "basic constituent layers" 2 to 4 · M formed on the base member 1 Will be described as a representative example with reference to FIGS. First, on the wood grain insert coating layer 4 (the natural wood grain pattern M is already formed) which is the uppermost layer of the “basic constituent layers” 2 to 4 · M,
Wood sealer layer 5 as "first coating layer for surface finishing"
Are formed [step S5].

One of the reasons for forming this wood sealer layer 5
One is to make the natural wood grain pattern M stand out while maintaining the color tone, and the other reason is the change over time (used for many years).
This is to prevent "cracking" from occurring in the wood material that has the possibility of "cracking". The wood sealer layer 5 is formed by diluting a paint having a predetermined component with an appropriate solvent, applying it once by spraying, and then drying it at room temperature for 5 minutes or more. The coating layer thus formed is a colorless and transparent coating layer having a hardness that sandpaper cannot be applied. In this case, the paint used for the wood sealer layer 5 is preferably, for example, one having the following components.

Union Paint Co., Ltd. Product No. 14-12 Product name Wood sealer Ingredient name Ingredient amount (wt%) Nitrogen 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%

On this wood sealer layer 5, a sanding sealer layer (lacquer coating layer for surface finishing) 6 is formed for eliminating unevenness of the surface of the layer 5 and making the coating unevenness inconspicuous to improve the appearance. Will be done [Step S
6]. The sanding sealer layer 6 is also provided for the purpose of improving the adhesiveness of the overcoat finishing layer 7 formed on itself, and is formed as a colorless and transparent coating layer. , A prescribed paint containing an abrasive,
For example, after using a lacquer thinner to dilute it to an extent that it is easy to apply, for example, once to 2 times by spraying
It is formed by being applied by recoating.

Then, after predetermined drying (drying time: 5 minutes or more), 320 is put on the surface of the sanding sealer layer 6.
A paper hanging operation using a sandpaper of No. to No. 400 is performed, for example, in a direction along the direction in which the natural wood pattern is formed to finish the flat surface. In this case, the sanding sealer layer 6 has an advantage that the paper application work is easy because the coating film is thick and soft. This sanding sheer layer 6
An overcoat finishing layer (topcoat finishing coating layer) 7 as a final finishing layer is formed thereon [step S7]. This topcoat finishing layer 7 is for finishing as a surface on which the natural wood grain pattern M appears naturally, and for example, using a clear lacquer having the following composition, for example, a single coating by a spraying method. It is preferably formed as a coating layer.

Regarding the clear lacquer, what is called "flat clear" (a name common to all companies),
Some are called "Pearl Flat" (the name of Wakoshin Chemical Industry Co., Ltd.). "Surface finish addition film layer" 5-7 by clear lacquer is formed through such steps, but the surface finish by this clear lacquer has a strong coating film and a thin film thickness, and has a beautiful matte appearance. Since it is finished as a layer that presents, and it is easy to repair and the cost is low, for example, various works and walls of rooms that are not so expensive but look higher than ordinary rooms (for example, general executive rooms) Suitable as a surface finish for decorative materials used for doors and the like. [III] "Surface finishing additional film layer" made of polyurethane
Regarding the formation of the above, in the third example of the decorative material manufactured by using the natural wood pattern forming apparatus according to the first embodiment of the present invention,
As in the case of the example, as a typical example, a case where a "surface finish addition film layer" made of polyurethane is formed on the surfaces of the "basic constituent layers" 2 to 4 · M formed on the base member 1 made of wood , FIG. 7 will be described. First, the first polyurethane clear layer (the first polyurethane coating film for surface finishing) is provided on the surface of the wood grain coating film layer 4 (the natural wood grain pattern M is already formed) which is the uppermost layer of the "basic constituent layers" 2 to 4 · M. Layer) 5'is formed [step S5 ']. The first polyurethane clear layer 5 'is for finishing to a mirror surface. For example, using a "mixed coating material" obtained by mixing a polyurethane resin-based base material having the following composition and a curing agent, by a spraying method, For example, it is preferably formed as a single coating layer.

On the surface of the first polyurethane clear layer 5 ', as a coating layer for improving the adhesiveness of the second polyurethane clear layer 7'which is an overcoat finishing layer (final finishing layer) described later, A polyurethane sanding sealer layer (intermediate coating layer for surface finishing) 6'is formed [step S6 ']. This polyurethane sanding sealer layer 6 ′ improves the adhesion of the final finishing layer, eliminates unevenness, makes the paint unevenness inconspicuous and improves the appearance, and as with the case of the wood sealer layer 5 described above, Formed as a coating layer that has the effect of not causing "cracking" in wood materials that have the possibility of "cracking",
A paint having the following composition is diluted with, for example, urethane thinner or lacquer thinner (preferably urethane thinner) to such an extent that it can be easily applied, and then, for example, by spraying.
By coating once or several times, a relatively soft and colorless and transparent coating layer is formed.

In this case, the number of times of application (film thickness) is determined in accordance with the user's desire or preference for the intended finished surface of the decorative material, and the thinner used for dilution is the urethane thinner as shown below. Of the lacquer thinner or the lacquer thinner of the first and second examples is preferable.

After the polyurethane sanding sealer layer 6'is dried, the surface thereof is, for example, 400
A paper-hanging operation using No. # 600 sandpaper is carried out, for example, in the direction along the grain forming direction to finish a flat surface. Thereafter, a second polyurethane clear layer (a second polyurethane coating layer for surface finishing) is formed on the surface of the polyurethane sanding sealer layer 6 ′ on which the paper has been hung.
7 'is formed [Step S7'].

The coating material used for the second polyurethane clear layer 7'and the forming method are, for example, a combination of a main agent and a curing agent having the same composition as the "mixed coating material" used for the first polyurethane clear layer 5 '. It is preferable that the above-mentioned "mixed paint" is used to form a coating layer of, for example, one coating or several coatings by a spraying method. The number of coatings (film thickness) in this case is also determined according to the user's request or preference for the finished surface of the intended decorative material, as in the case of the first polyurethane clear layer 5 '.

Through these steps, the "surface finish addition film layer"5'to7'of polyurethane is formed, but the surface finish of this polyurethane is higher in cost than the surface finish of clear lacquer, Although it is difficult to repair, it is finished as a layer with a luxurious and luxurious appearance, and because the coating layer is hard and resistant to moisture, it can be used in high-end furniture, building columns, etc. Suitable for surface finishing of decorative materials used for. [IV] Materials that allow liquids to permeate (excluding wood materials)
Manufacturing of a decorative material using pigment paint when using as a base member, for example, mortar material, cement material (concrete material), gypsum board material, etc. When a material that causes "mold" or "acne" on its surface over time is used for the base member, the pigment paint formed on the surface of the base member is used for the "mold" or "acne" that occurs. The "basic constituent layer" and the "surface finishing additional film layer" may have irregularities or the like and the natural wood grain pattern M may be deformed.

Therefore, as shown in FIG. 8, the surface 1 of the base member 11 (hereinafter referred to as “mold member for preventing mildew”) 11 using a material that easily causes such “mold” or “actuate”.
When the "basic constituent layer" is formed on 1a, its surface 1

Product No. 033-1150 Product name Emulsion clear sealer Standard JIS A 6910 Multi-layer finish coating material (The component name and the amount of components have been omitted since they were mentioned above.) In the fourth example of 1A, even when the base member is made of a material that easily causes "mold" or "acne", it becomes possible to prevent "mold" or "acne", and a beautiful natural wood grain pattern is obtained. Obtainable. Thereafter, the "surface finishing additional film layer" 5 to 7 or 5 'to 7' is formed on the "basic constituent layer" 2 to 4 · M using a pigment paint to produce a desired decorative material. [V] Manufacturing of a decorative material using a pigment paint when an opaque material that does not allow liquid to permeate is used as a base member A material such as a metal material or an opaque plastic material that does not allow liquid to permeate (hereinafter referred to as “opaque material”). Substrate member for smooth surface required "
Or a material such as a glass material or a transparent plastic material that does not allow liquids to permeate (hereinafter referred to as "a transparent base member for smooth surface-requiring measures") has a smooth surface or back surface. Therefore, the "basic constituent layer" 2 is provided on the front surface or the back surface (both smooth surfaces) of the base member requiring smooth surface measures.
If the lowest coating layer of 4 to M is directly applied, there is a risk that the applied coating layer may have a problem such as peeling.

In this case, in the case where the smooth surface measure base member is an opaque smooth surface measure base member such as a metal material or an opaque plastic material, the opaque smooth surface measure base member surface and the "basic structure" are used. Layer 2 to 4 · M, an “adhesion-improving base treatment layer” (also referred to as “adhesion-improving base addition film layer”) is formed, and a “basic constituent layer” 2 to which a pigment coating is used
It is necessary to keep good adhesion performance of 4 · M. In addition, the fifth example of the decorative material 1A is such that the "adhesion-improving underlying additional film layer" is applied. Naturally, the configurations of the “basic constituent layers” 2 to 4 · M themselves using the pigment paint are the same as those in the case of the first example of the decorative material 1A.

As shown by the reference numerals in parentheses in FIG. 8, reference numeral 21 is an opaque smooth surface-necessary substrate member 21 made of a metal material or opaque plastic material, and 22 is an opaque smooth surface-necessary substrate member 21. Surface 21a and "basic constituent layer" 2
This is the “adhesion-improving undercoating film layer” formed between the polyurethane surfacer layer 2 and the polyurethane surfacer layer 2 .about.4 · M. The "adhesion-improving underlying additional film layer" 22 is formed as an underlying adhesive layer using, for example, the following coating material and applied by coating once or twice by, for example, a spraying method [step S21].

As a result, in the fifth example (see FIG. 8) of the decorative material manufactured by using the apparatus for forming a natural wood pattern according to the first embodiment of the present invention, even if the "basic constitution Even when the layers “2 to 4 · M are formed, it is possible to ensure good adhesion between the surface 21a of the smooth surface-necessary countermeasure base member 21 and the polyurethane surfacer layer 2,
It is possible to obtain a beautiful natural wood grain pattern without a phenomenon such as peeling of the coating layer. After this, the "basic constituent layer" 2-4.M using the pigment coating, and the "surface finishing additional film layer" 5-7
Alternatively, 5 ′ to 7 ′ are formed to manufacture a desired decorative material. [VI] Manufacturing of a decorative material using a pigment paint when a transparent material having a smooth surface at least on the back surface is used as a material that does not allow liquid to permeate. On the other hand, a glass material or a transparent plastic material. A material such as a material that does not allow liquid to permeate therethrough, and at least the back surface is formed as a smooth surface. A "basic constituent layer for transparent underlayer" (a constituent layer corresponding to "basic constituent layers" 2 to 4 · M) is formed on the back surface (smooth surface) 31a of the base member 31, and a transparent smooth surface-requiring base member 31 The natural wood grain pattern M is seen through from the front side of the plastic material through the glass material.

Therefore, the layer arrangement of the "basic constituent layer for transparent underlayer" when viewed from the transparent base material for a smooth surface-requiring base member is the "basic constituent layers" 2 to 4 · M in the first embodiment. The arrangement is the reverse of the arrangement. Further, the back surface finish of the decorative material to be combined with the "basic constituent layer for transparent base" (corresponding to the surface finish for the first example of the decorative material 1A) is a mirror finish method using polyurethane. The layer structure of the layers is also opposite to the layer structure in the case of the polyurethane surface finishing method in the first example of the decorative material 1A.

FIG. 9 shows an example of forming a "basic constituent layer for transparent underlayer" on the back surface of the transparent base member 31 for smooth surface-requiring measures, which is the first embodiment of the present invention. It is a 6th example of the decorative material 1A produced using the forming apparatus of the natural wood pattern concerning this. In FIG. 9, reference numeral 31 denotes a transparent smoothness-necessary surface-preventing base member 31 made of a glass material or transparent plastic material, and reference numeral 32 denotes an “adhesiveness” formed on the back surface 31a of the smoothness-necessary surface-preventing base member 31. "Improved undercoat layer" (also referred to as "adhesion-improved adhesion layer").

The paint used for the "adhesion improving adhesion layer" 32 has, for example, the same properties as the paint used for the "adhesion improving base treatment layer" 22 of the fifth example (FIG. 4) of the decorative material 1A. The following coating material to be possessed is selected, and is formed by coating once or twice by spraying, for example [Step S31]. The adhesion performance (peeling resistance) of the "adhesion-improving adhesion layer" 32 is not particularly excellent, but of the plastic material or glass material where the coating film layer is not damaged by external force. Since it is the back side, it does not matter. Incidentally, when the back surface of the transparent base member 31 requiring smooth surface is rubbed to make it rough, the adhesiveness of the coating layer is naturally improved. In such a case, the "adhesion improving adhesion layer" is used. It is not necessary to form "32".

As described above, the layer structure of the back surface finishing layer in the sixth example is opposite to the layer structure in the case of the polyurethane surface finishing method of the sixth example for the first example of the decorative material 1A.

Through these steps, a "back surface finishing layer of a decorative material"("back surface finishing additional film layer of polyurethane") having a hard coating film and strong against moisture is formed. In 6 examples, the desired natural wood grain pattern M is viewed through the glass material or the plastic material from the surface side of the glass material or the transparent plastic material, so that it is a decorative material having a luxurious and expensive appearance. It will be suitable for the surface finish of the used decorative material.

[VII] In the case of using oil-based paint (oil paint) By the way, among the decorative materials used for the outer wall of a building, etc.
For example, a decorative material for exterior using a non-metal material such as mortar material, cement material, board, wood for wooden building for the base member (base material) 1 and an external decorative material using metal for the base member 1 are: However, it is not a cosmetic material that is required to be as beautiful as interior decoration materials. Therefore, it is necessary to apply a finish using an oil paint oil paint (hereinafter, abbreviated as “OP paint finish”) to such exterior decorative materials and interior decorative materials that are not so required to be beautiful. It will be possible. The present invention relates to the seventh and eighth examples of the decorative material 1A shown below.

[0124] Compared with the above-mentioned decorative material using the paint based on the "pigment", the decorative material with the OP paint finish has a practical advantage that it is cost effective and has good workability. And has the advantage of being resistant to moisture and heat. The seventh example of decorative material is mortar

Degree (tilt), line of hair and rubbing direction (predetermined direction)
Similar to the above example, the desired shape of the second rubbing line can be obtained by appropriately setting the respective factors such as the angle between and.

Since the first and second rubbing lines as described above are a large number of fine fine uneven rubbing lines that are combined in a predetermined direction as a whole, the first rubbing line pattern and the second rubbing line pattern are combined. By changing and synthesizing variously, it is possible to form an uneven rubbing line that realizes a desired natural wood grain pattern M. When the specific example of forming the second rubbing line is “Hechima”, the size (density), shape, hardness, contact pressure, number of uses, the degree of inclination with respect to the surface of the wood grain coating, or A desired pattern can be realized by variously changing each factor such as the relation of the angle with the predetermined direction according to the purpose.

In order to obtain a decorative material using the "natural grain pattern forming device" according to the second embodiment of the present invention configured as described above, prior to the coating film formation by the coating film forming means 96. The same pretreatment as described above is required, and the base member 1 on which the pretreatment is completed is placed on the first belt conveyor 91 to drive the first belt conveyor 91 in the direction of arrow d, and the second belt conveyor 93 also It is driven in the direction of arrow d. Prior to this, the same "composite pigment" and "aqueous sealer" as described above are applied to the solution tank 9 of the coating film forming means 96.
7 is filled with the paint P selected as described above.

Then, the coating brush 98 does not rotate until the brush 98c of the coating brush 98 comes into contact with the end edge of the substrate member 1 due to the movement of the substrate member 1, and when the brush 98c comes into contact with the brush 98c, the paint P is crushed. Is applied to the edge of the base member 1. Further, when the base member 1 is moved in the direction of the arrow d, the entire coating brush 98 is rotated in the direction of the arrow f while being crushed by the upper surface of the base member 1, and the brush 98c soaked with the paint P is further used as the base member. 1. The paint P is applied on the upper surface.

The coating speed of the coating material P thus made, in other words, the moving speeds of the first belt conveyor 91 and the second belt conveyor 93 are the same as the first rubbing by the first hand pad 101 at the next stage from the coating by the brush 98c. It is necessary to set a value such that a time is elapsed such that the applied paint P is not completely dried in the distance until the line is formed. If the coating speed is too fast, the liquid coating is not dried, so the first hand pad 01 in the next stage
Therefore, the first rubbing line is not formed, and if the coating speed is too slow, it becomes completely dry and the first rubbing line cannot be formed.

Therefore, it is desirable that the application speed is such that the first hand pad 101 is in a semi-dry state when the applied coating material reaches the first hand pad 101. When the coating film in such a semi-dry state reaches the first hand pad 101, the coating material is rubbed by the first hand pad 101, and when the base member 1 is further moved in the direction of arrow e, the second hand of the next stage is moved. The paint is rubbed again by the pad 103, and the first rubbing line is formed by the combined action with the second hand pad 103 described later. This first rubbing line is
As described above, by appropriately setting the respective factors such as the size, shape, hardness, contact pressure, and number of uses of the first handpad 101 and the second handpad 103, the desired shape of the first rubbing line can be obtained. can do.

The contact pressure of each of the first hand pad 101 and the second hand pad 103 can be adjusted by moving the pressure roller 111 and the shaft 113 in the vertical direction.
For example, the pressing force can be increased by moving each of the pressure roller 111 and the shaft 113 in the upward direction, and can be decreased by moving the pressing roller 111 and the shaft 113 in the downward direction. Then, when the moving frame 64 is further moved in the direction of arrow a, the rubbing line formed by the first handpad 101 is further rubbed by the second handpad 103, and the first handpad 101 and the second handpad 103 form a composite line. The first rubbing line to be formed in the above will be formed.

Further, when the base member 1 is moved in the direction of the arrow e, the first brush tip portion 106 finely forms on the surface of the relatively large uneven portion of the first rubbing line formed by the first rubbing line forming means 100. When the moving frame 64 is further moved in the direction of arrow a, the second brush tip 10 is formed.
Fine unevenness is formed in a complex manner by 8 and the second rubbing line is formed by the second rubbing line forming means 105. As described above, the rubbing line formed by the second rubbing line and the first rubbing line is the size / shape / hardness / contact pressure / Factors such as the number of uses, the length of the brush, the hardness, the density, the contact pressure, the number of installations (the number of uses), and the surface of the wood grain coating for each of the first brush tip 106 and the second brush tip 108. The desired shape of the rubbing line can be obtained by appropriately setting each factor such as the degree of inclination (tilt) with respect to the angle, and the angle between the line of hair and the rubbing direction (predetermined direction).

The base member 1 on which the application and rubbing lines have been formed on the upper surface of the pretreated base member 1 in this manner is guided by a plurality of rollers 116 provided on the pedestal 115 and taken out. Therefore, since the first and second rubbing lines are a large number of fine fine uneven rubbing lines that are combined in a predetermined direction as a whole, the pattern of the first rubbing line and the pattern of the second rubbing line can be variously changed. By synthesizing, it is possible to form the uneven rubbing lines that realize the desired natural wood grain pattern M. After the work of forming the uneven rubbing lines is completed, a desired natural wood grain pattern M is formed, for example, by performing a drying work at room temperature for about 5 to 30 minutes.

When the natural wood grain pattern M is formed on the back surface of the base member which is made of glass or transparent plastic material and at least the back surface of which is a smooth surface, first, on the lower surface of the wood grain coating layer 4. The first rubbing line is formed on the first rubbing line, and then the second rubbing line is formed on the lower side surface of the first rubbing line surface. Will be formed. Further, the time of the above-mentioned drying operation may be changed depending on the environmental temperature at that time.

As described above, the natural grain pattern forming apparatus 118 according to the second embodiment of the present invention has the following effects.

The second color portion 172 is formed by overlapping the color portions 172.
It is possible to know the actual state of the finished product when the pattern of the third pattern portion 169 is created in the case of the background color.

Further, the first to fifth parts of the base member sample plate 170
By superimposing the first to third color portions 162 to 164 of the grain-filled color reference plate 160 on any one of the color portions 171 to 175, it is possible to obtain an actual finished product having a constant grain pattern and different colors. You can know the condition. Therefore, the state of the actual finished product can be known by superimposing the grain-filled color reference plate 160 or the grain-filled pattern reference plate 165 and the base member sample plate 170, and a finished sample was prepared and confirmed. There is a great advantage that it is not necessary to formally create a decorative material later.

The present invention is not limited to the natural grain pattern forming devices according to the various embodiments described so far, and various modifications can be made without departing from the scope of the invention. . For example, the first and second aspects of the present invention
