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, used for the construction, furniture, etc. of natural wood grain patterns that are very similar to the beautiful, deep and soft wood grain of high quality natural wood. Natural materials such as wood materials, mortar materials, cement materials (concrete materials), gypsum materials, board materials, etc., into which liquid permeates, and metals, plastic materials, glass, etc., into which liquid does not permeate The present invention relates to a decorative material having a wood grain pattern.

2. Description of the Related Art Use of high-quality wood represented by, for example, Japanese cypress and cedar wood, and high-grade wood for furniture, represented by paulownia wood and mahogany, for buildings and furniture in a raw state. Then, the price becomes extremely expensive. For this reason, 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, so whether the high-grade wood is still used in its raw form. The method of pretending to be like this has been widely used from the past.

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, as the yearning for these high-grade timbers has increased, the demand for the high-grade timbers has continued to increase, and therefore these high-grade timbers have been remarkably decreasing on a global scale.

Therefore, on the one hand, the method of painting or printing is used in order to prevent the environmental destruction on a global scale by minimizing the felling of these high-grade raw trees, and on the other hand to cope with the decrease of the high-grade raw trees. Then, 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.

For example, in the method disclosed in Japanese Examined Patent Publication No. 49-46135, first, a surface of a base material (corresponding to the base member of the present invention) made of appropriate wood or the like is flattened by using an undercoat paint. The undercoat layer is formed by performing any desired coating, and an arbitrary striped pattern forming a wood pattern, for example, is drawn on the dried undercoat layer using a silicon resin coating agent having a small surface tension.

After that, an overcoat layer made of a transparent, semitransparent or opaque paint is formed over the entire surface of the silicon resin coating layer having the striped pattern. At this time, in the step of forming the overcoat layer, the effect that the paint of the overcoat layer where the silicon resin coating layer formed on the undercoat layer is present is repelled and squeezes to the periphery of the area where the silicon resin coating is present ( The so-called "water drainage effect" and "eye-repelling effect") occur, and this effect is used to bring out 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 using a flow coater (pattern roll) or a brush having a structure in which bristles are appropriately thinned. Will be done.

Further, Japanese Patent Publication No. 58-44036 (Japanese Patent Laid-Open No.
52-96715), firstly, for example, an acrylic emulsion-based water-based filler is applied to the surface of a base material made of lauan plywood or the like, and this coating layer is dried and polished, and then, for example, A light acrylic lacquer surfacer is applied over the entire surface to form an intermediate coating layer.

After that, a clear acrylic lacquer is applied to the surface of the facer 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 aid is applied. . At this time, the printing agent remains in a wet state only on the surfacer surface other than the clear coating surface. Then, while the printing agent is in an undried or contact-dried state, ordinary ink is used to blur the desired pattern of wood grain, conduit, etc., and the gloss of the same composition as the printing agent containing the foaming aid is applied. The skeleton is printed using eraser ink.

After that, 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. 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 adhered to the surface of a base material made of an appropriate plywood or the like, and the surface of the wood decorative veneer is brushed. At this time, of the spring wood part and the autumn wood part that make up the 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 that it becomes a convex shape. It 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, it is possible to color the wood decorative veneer while maintaining a soft appearance without "color unevenness".

[0013]

[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, in the method of Japanese Patent Publication No. 58-44036, it is necessary to carry out blurring printing for preventing the skeleton portion of the pattern portion such as wood grain and conduit formed by the printing method from appearing as a hard pattern. Therefore, 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. There will be major problems.

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 unevenness on the surface of the wooden decorative veneer. 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. Therefore, the applicant invented a cosmetic material that produced a high-quality natural wood grain pattern very similar to the case of using high-quality natural wood and a manufacturing method therefor, using a completely different principle from the conventional idea. The application was filed as Japanese Patent Application No. 5-208453, dated July 30, (hereinafter referred to as the “prior invention”).

According to the invention of this prior application, first, a coating material representing one of the constituent colors forming a desired shade of a natural wood pattern is provided on the surface of a base material of a decorative material used for construction, furniture and the like. Form an emulsion layer. Then, 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 base material Using a plurality of brush members provided over the entire area in the width direction, the surface of the oil color layer is brushed in the direction of forming the natural wood grain pattern 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 seeping in), 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 gives 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 the light and shade stripe of the color represented by this oil color layer. It will appear in a mixed state with the pattern. That is, the color represented by the light and shade 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 bleeds 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 natural wood grain is formed is determined by the brush member and the base material. If properly set in relation to the relative displacement speed, the target natural wood grain pattern can be obtained. And, on the surface of the emulsion layer with the oil color layer after this natural wood grain pattern is formed,
This is to form a substantially transparent colorless or colored additional film layer (which is also a protective layer) to fix the natural wood 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, when the decorative material is manufactured, it is exposed to sunlight or illuminating light. It is also necessary to take measures to prevent discoloration or fading that would impair the appearance of the wood grain pattern even when it is shot, and it is necessary to devise measures for that.

The present invention has been made in view of the above circumstances, and its purpose is to use no precious high-quality natural wood and to use a paint having a special composition. Moreover, while significantly reducing the manufacturing cost, it is possible to provide a decorative material having a natural wood grain pattern used for construction and furniture, which can prevent discoloration or fading due to sunlight or illumination light, and a manufacturing method thereof. is there.

Examples As described above, the present invention is applicable to materials such as wood materials including veneer plywood, mortar materials, cement materials (concrete materials), gypsum materials, board materials, etc., into which liquid can permeate, and metals. Material, such as transparent or non-transparent plastic material and glass material, which liquid does not permeate (hereinafter,
On top of the "base member" or "base material"), a natural wood grain pattern (hereinafter simply referred to as "natural wood grain pattern") that closely resembles the beautiful, deep and soft wood grain of high-quality natural wood A decorative material with a natural wood pattern used for construction and furniture (hereinafter abbreviated as "cosmetic material")
The purpose is to produce.

In this case, the decorative material has a wood grain pattern-containing coating layer (hereinafter abbreviated as "wood graining coating layer") formed as a coating layer for realizing a desired or desired natural grain pattern. It will be formed by applying various coating layers mainly on the base member, but in the present invention, for example, the desired natural wood grain pattern finish, such as teak pattern finish and rosewood pattern finish. , Several kinds of finishes such as walnut pattern finish are planned. Furthermore, as a paint for forming the wood grain coating layer, a paint containing a pigment as a main component (hereinafter referred to as "pigment paint"), oil paint, oil paint, We plan to use cashews.

Further, there are two planned methods of finishing the "surface finish layer of the decorative material" when forming a natural wood grain pattern using a pigment paint, for example, clear lacquer surface finish and polyurethane surface finish. Therefore, the types of decorative materials produced in the present invention are different in the base member used,
Due to the difference in the pattern finish of the natural wood grain pattern, the difference in the paint used for the wood grain coating layer, and the difference in the method of finishing the surface of the decorative material when using the pigment paint, it will be diverse and diverse. Thus, the layer structure of the coating layer formed on the base member also differs.

This necessitates a production method similar to a variety of small-volume production, which not only complicates process control, quality control, product control, etc., but also causes an increase in cost. There will be problems.

Therefore, in the present invention, in order to avoid such a situation, among all the coating layers formed on the base member, the first coating layer formed on the surface of the base member is used to form the wood grain coating film. Layer structure of a specific coating layer group up to the layer, and a predetermined grain patterning work to be applied to this grain coating layer (hereinafter,
The concept of "basic constituent layer" is set with the natural wood grain pattern formed by "the wood graining work"), and the type of base member, the type of natural wood grain pattern finish, the wood grain coating Regardless of the type of paint used for the film layer and the surface finish, this "basic constituent layer" is configured so that it can be used in common with most of the decorative materials to produce a wide variety of decorative materials. So that it can be done easily.

Therefore, in the following description, based on such an idea, first, a "basic constituent layer" for forming a wood grain coating layer using a pigment paint will be described as a representative example, and subsequently, The "surface-finishing additional film layer" formed during the surface finishing of the "basic constituent layer" will be described, and further, "base treatment" when the "basic constituent layer" is formed on each type of base member. "Layer" will be described.

Since the work of inserting a wood grain pattern when forming a natural wood grain pattern using a pigment paint is common to all the base members, it will be described later. In addition, in the case of transparent base materials such as transparent plastic materials and glass materials, "basic constituent layer for transparent base", "basic constituent layer for OP" when using oil paint oil paint, cashew (lacquer) paint The "basic constituent layer for cashew" when used will be described later. [I] Formation of "basic constituent layer" using pigment paint.

The formation of the "basic constituent layer" will be described by taking a case of forming the base member (including plywood) made of wood as a typical example. FIG. 1 is a perspective view schematically showing the constitution of a first embodiment of a decorative material having a natural wood grain pattern according to the present invention, and a coating film formed on a base member for easy understanding of the layer constitution. The layers are sequentially exposed.
FIG. 2 is a cross-sectional configuration diagram showing a configuration of a cross section taken along line AA in FIG.

In the first embodiment, first, the base member 1 of a decorative material made of an appropriate wood material is prepared. In the first embodiment, for example, a single plate or an appropriate material is used as the base member 1. Commercially-made veneer plywood composed of, for example, a three-piece structure (for example, "rawan veneer" or "cinna veneer")
Will be selected [step S1]. in this case,
The surface 1a of the base member 1 (the surface to be the surface of the decorative material; the same applies hereinafter) is subjected to a paper hanging operation (sander) using, for example, No. 180 sandpaper, to obtain a grain of wood for veneer or plywood. Finishes to a flat rough surface that appears as 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 is curved or uneven, first, the surface 1a is ground to a substantially flat surface with, for example, an electric plane (planer), and then a paper-hanging operation using sandpaper No. 180 is performed. And finish it to a flat rough surface. In either case, the paper hanging direction in the paper hanging operation does not matter.

Next, as shown in FIGS. 1 and 2, 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, the polyurethane surfacer layer 2 which is the basic color tone coating layer of the "basic constituent layer" is formed by applying several times (for example, two times) by a spraying method known per se [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 liquids A selected from the following liquids A into 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 wood grain 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.

Polyurethane Surfacer Red Rust Color 95% Liquid A (Part 2) Polyurethane Surfacer Black 5% Liquid A (Part 3) In any natural woodgrain pattern M, B
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 different material, dilute (mix) it into a hard material.

Other paints can be used as the paint for the polyurethane surfacer layer 2. For example, acrylic lacquer or phthalic acid paint (oil paint) can be used. After the polyurethane surfacer layer 2 is applied in this manner, the sandpaper 180-
Paper is hung on a sander using No. 240 to form a predetermined rough surface 3 of the paper [step S3].

After the work of forming the predetermined rough surface 3 of the paper is completed, the predetermined grain-finishing paint is uniformly applied to the rough surface 3 of the paper, and the grain-finishing coating layer 4 as the grain-finishing coating film 4 is applied. Are formed [step S4]. The wood grain coating paint used for forming the wood grain coating film layer 4 includes a "composite pigment" for realizing the intended color tone of the natural wood grain pattern M, and an "water-based sealer" which plays a role of an adhesive (paste). Will be prepared by mixing.

In this case, the "composite pigment" is "black".
Two to three types of "red" and "yellow" pigments are mixed at a predetermined ratio, and the mixed composite pigment is mixed in a process of blending with an AS aqueous sealer (or an aqueous clear sealer). By doing so, it is changed to a “composite pigment” composed of powder of small particles. The "water-based sealer" is originally used as an adhesive or an undercoating agent for a base material or a base layer, and is diluted with an appropriate amount of water before use. In this case, as the base material,
Materials such as wood materials, mortar materials, cement materials, board materials, etc., into which liquid can permeate are selected.

Specific examples of the "composite pigment" and the "aqueous sealer" used in the wood grain coating layer 4 will be described below.
The kind of the color tone of the [composite pigment], the manufacturer, etc. and the component, the manufacturer, etc. of the [water-based sealer] are not limited to these specific examples.

[0068]

[Table 2]

[0069]

Then, before the wood grain coating film layer 4 is not dried, the wood grain pattern filling work as outlined below is performed.
This wood grain patterning work is performed, for example, by using a hand pad as a first wood grain pattern coating member (for example, “Scotch Bright (manufactured by Sumitomo 3M Co., Ltd.) before the wood grain coating film layer 4 is dried. Product name): Product number 744
7) in a predetermined direction on the wood grain coating layer 4 (direction along the wood grain when the base member 1 is a wood material)
The first rubbing line is formed by rubbing the first rubbing line on the first rubbing line by using a brush member or a "hachima" (suitable for a chamfered portion) as the second wood grain pattern forming member. The operation of rubbing to form the second rubbing line is performed.

When this kind of work is performed, the two types of rubbing lines become a large number of fine fine uneven rubbing lines that are oriented in a predetermined direction as a whole, so the pattern of the first rubbing line and the second rubbing line are formed. And the pattern of No. 1 are variously combined to form the uneven rubbing line that realizes the desired natural wood grain pattern M.

That is, in the case of a handpad, factors such as size, shape, hardness, contact pressure, and number of uses, and in the case of a brush member, length, hardness, density, contact of the bristles. The factors such as the pressure, the number of installations (the number of uses), the degree of inclination (tilt) with respect to the surface of the wood grain coating film layer 4, and the angle between the line of hair and the rubbing direction (predetermined direction) are further described in “ In the case of "Hechima", each factor such as the size (density), shape, hardness, contact pressure, number of uses, the degree of inclination with respect to the surface of the wood grain coating layer 4, or the relationship with the angle with a predetermined direction By changing variously according to the purpose, it becomes possible to realize a desired natural wood grain pattern M.

At this time, the first rubbing line and the second rubbing line
The rubbing line may be formed by an appropriate manual (manual) rubbing motion or a mechanical rubbing motion. For example, in the case of mechanical rubbing motion, for example, the specification of 1993 patent application No. 208453 “Natural wood grain decorative material and its manufacturing method” filed by the applicant on July 30, 1993 It is also an example to use the apparatus and method shown in the drawings and drawings, or the apparatus and method according to them.

After the work of forming the uneven rubbing lines is completed, a desired natural wood grain pattern M is formed by performing a drying work at room temperature for about 5 to 30 minutes, for example. When the natural wood grain pattern M is formed on the back surface of the base member which is made of a glass material or a transparent plastic material and at least the back surface of which is a smooth surface, first, the first wood layer is formed on the lower surface of the wood grain coating layer 4. By forming rubbing lines and then forming second rubbing lines on the lower side surface of the first rubbing line surface, a large number of fine uneven rubbing line patterns corresponding to the desired natural wood grain pattern M are formed. It will be. Moreover, the time of the above-mentioned drying operation may be changed depending on the environmental temperature at that time.

In this way, 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 steps [Step S2] to [Step S4]. The pattern M constitutes the “basic constituent layers” 2 to 4 · M of the present invention when the pigment paint is used. In the above description, the surface 1a of the base member 1 is a flat rough surface, or the rough surface of the paper 3 is used.
However, it should be noted that forming these rough surfaces 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] About formation of "surface finish layer of cosmetic material" by clear lacquer.

In the second embodiment of the present invention, the surface of the "basic constituent layers" 2 to 4 · M formed on the base member 1 made of a wood material is coated with a "surface finishing layer of a cosmetic material" (clear lacquer). Hereinafter, a case of forming a “surface finishing additional film layer” will be described as a typical example with reference to FIGS. 1 and 2.

First, as a "first coating layer for surface finishing" on the wood grain coating layer 4 (the natural wood grain pattern M is already formed) which is the uppermost layer of the "basic constituent layers" 2 to 4M. The wood sealer layer 5 is formed [step S5]. One of the reasons for forming the wood sealer layer 5 is to make the natural wood grain pattern M stand out while maintaining the color tone, and the other reasons are:
This is to prevent "cracking" from occurring in the wood material that may "crack" due to aging (used for many years).

The wood sealer layer 5 is formed by diluting a paint having a predetermined component with an appropriate solvent, applying it once by a spraying method, and then drying it at room temperature for 5 minutes or more. However, the coating layer formed in this way becomes a colorless and transparent coating layer having a hardness that does not allow sandpaper to be applied. In this case, as the paint used for the wood sealer layer 5, for example, the following components are preferable.

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 irregularities on 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, use a lacquer thinner to make it diluted to an extent that is easy to apply, and then spray it once to 2 times.
It is formed by being applied once.

Then, after predetermined drying (drying time: 5 minutes or more), 320 is put on the surface of the sanding sealer layer 6.
The paper-hanging work using the No. to No. 400 sandpaper is carried out, for example, in the direction along the forming direction of the natural wood grain pattern to finish it into a flat surface. In this case, the sanding sealer layer 6 has the advantage that the coating operation is easy because the coating film is thick and soft.

On this sanding sealer layer 6, a top coat finish layer (top coat finish coat layer) 7 as a final finish layer.
Are formed [step S7]. This overcoat 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, by a spraying method, for example, 1
It is preferably formed as a coating layer of multiple coatings.

Union Paint Co., Ltd. Product No. 13-03 Product name Clear lacquer-Ingredient name Ingredient amount (wt%) Nitrogen cotton 13.5% Alkyd resin 14.5% Plasticizer 2.0% Aromatic hydrocarbon solvent 30.5% Ester-based Solvent 30.0% Alcohol solvent 9.5%

Regarding the clear lacquer, what is called "flat clear" (a name common to all companies),
There is also what is called "Pearl Flat" (Washin Chemical Industry Co., Ltd.) Through these steps, "surface finish addition film layers" 5 to 7 are formed by the clear lacquer. Is a layer with a strong coating film and a thin film thickness, and it is finished as a layer that has a beautiful matte appearance, and it is easy to repair and the cost is low. Is suitable as a surface finish for a decorative material used for walls or doors of a room that looks high-grade (for example, a general executive room).

By the way, as described in the section of "Prior Art", when manufacturing a decorative material, even when it is used for a long period of time in an environment exposed to a living space, discoloration due to sunlight or illumination light or It is required that no fading occurs. Therefore, the present inventor requested a public institution to carry out a test regarding discoloration and fading of the decorative material of the second example. The decorative material of the sample used in this test uses a 3 mm thick veneer plate as the base member 1 and has a "basic constituent layer" on the surface thereof.
2 to 4 · M and “surface finishing additional film layer” 5 to 7 by clear lacquer.

In this case, two samples each of which has three kinds of natural wood grain pattern M of teak pattern finish, rosewood pattern finish, and walnut pattern finish are prepared and provided to the Tokyo Metropolitan Industrial Technology Center which is a public institution. We asked for the "accelerated weathering test (100 hours)". Then, the Industrial Technology Center conducted a 100-hour accelerated weathering test with the JIS K 5400 (1990) General paint test method using the 9.8.1 sunshine carbon arc lamp system, and all 6 samples showed "abnormality". The result of visual evaluation was "No" (July 11, 1994).

This is because the decorative material for construction according to the present invention is
It eloquently demonstrates that it has excellent performance that does not cause discoloration or fading due to sunlight or illumination light even when used for a long period of time in an environment exposed to a living space. [III] "Surface finishing additional film layer" made of polyurethane
The formation of.

In the third embodiment of the present invention, as in the case of the second embodiment, the surface of the "basic constituent layers" 2-4.M formed on the base member 1 made of wood is made of polyurethane. As a typical example, the case of forming the “surface finishing additional film layer” will be described with reference to FIGS. 2 and 3.

First, the first polyurethane clear layer (first surface finishing layer) is formed on the surface of the wood grain coating layer 4 (the natural wood grain pattern M has been formed) which is the uppermost layer of the "basic constituent layers" 2 to 4 · M. Polyurethane coating layer) 5'is formed [Step S
5 ']. This first polyurethane clear layer 5'is for finishing a mirror surface, for example, by using a "mixed paint" in which a polyurethane resin-based main component having the following composition and a curing agent are mixed, by a spraying method, For example, it is preferably formed as a one-time coating layer.

[Main Agent] Union Paint Co., Ltd. Product No. 16-27 Product name Polyurethane sanding A liquid Ingredient name Ingredient amount (wt%) Polyester for polyurethane 41.5% Thickener 1.5% Polishing agent 5.0% Ester solvent 39.0 % Ketone-based solvent 7.0% Aromatic hydrocarbon-based solvent 6.0%

[Curing agent] Union Paint Co., Ltd. Product No. 16-271 Product name Polyurethane sanding B liquid Ingredient name Ingredient amount (wt%) Isocyanate for polyurethane 27.0% Ester solvent 61.0% Aromatic hydrocarbon solvent 12.0%

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 a finish layer (final finish 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. Like the case of the wood sealer layer 5 described above, there is a possibility of "cracking" due to aging. It is formed as a coating layer having the effect of not causing "cracking" in the wood material, and a paint having the following composition is diluted to an extent such that it can be easily applied with, for example, lacquer thinner, and then applied once by, for example, a spraying method or By coating 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 according to the user's desire or preference for the intended finished surface of the decorative material, and the lacquer thinner used for dilution is the following first and second examples. Those having a composition such as are preferable.

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

The coating material used for the second polyurethane clear layer 7'and the method for forming the same include, for example, a main agent and a curing agent having the same composition as that of the "mixed coating material" used for the first polyurethane clear layer 5'described above. 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 times of application (film thickness) in this case is also determined according to the user's desire or preference for the desired finished surface of the decorative material, as in the case of the first polyurethane clear layer 5 '.

Through these steps, the "surface finish addition film layers"5'to7'of polyurethane are formed, but the surface finish of this polyurethane is higher in cost than the surface finish of clear lacquer, Although there is a problem that it is difficult to repair, it is finished as a layer with a luxurious and luxurious appearance, and the coating layer is hard and resistant to moisture, so high-quality furniture, building columns, etc. It will be suitable for surface finishing of decorative materials used for. [IV] Manufacturing of decorative materials using pigment paint when materials (excluding wood materials) that allow liquid to permeate are used for the base member. Materials such as mortar materials, cement materials (concrete materials), gypsum board materials, etc. that allow liquids to seep into them and cause "mildew" or "acuity" on the surface after a long time has passed. When used as a base member, due to the "mold" or "acuity" that occurs, the "basic constituent layer" or "surface finish addition film layer" using the pigment coating formed on the surface of the base member has irregularities, etc. May occur and the natural wood grain pattern M may be deformed.

Therefore, such a "mold" or "acme"
When a "basic constituent layer" is formed on the surface 11a of a base member (hereinafter, referred to as "mold prevention base member") 11 using a material that easily causes the like, the surface 11a and the "basic constituent layer" 2 Forming a "mold prevention base treatment layer" (also called "mold prevention base addition film layer") between 4 and M
The need arises to prevent the occurrence of squeaks and "acne."

The fourth embodiment of the present invention is an embodiment in the case of producing a decorative material having this "antifungal base addition film layer". In addition, it goes without saying that "basic constituent layers" 2-4.
The configuration of M itself is the same as that of the first embodiment. In FIG. 4, reference numeral 12 denotes a “mold prevention underlayer addition film layer” formed between the surface 11a of the base member 11 for preventing mold and the “basic constituent layers” 2 to 4 · M, for example, “basic constituent layer”.
The same paint as the "water-based (AS) sealer" used in the wood grain coating layer 4 is used, and is formed by the same coating method [step S11].

[Water-based sealer] Rock Paint Co., Ltd. Product No. 033-1150 Product name Emulsion clear sealer Standard JIS A 6910 Multi-layer finish coating material (The component names and component amounts have been mentioned above, so it is omitted.)

As a result, in the decorative material of the fourth embodiment, even if the base member is made of a material that easily causes "mold" or "acne", it is possible to prevent "mold" or "acne". You can get beautiful natural wood grain pattern. After this,
A desired surface material is manufactured by forming the "surface finishing additional film layer" 5-7 or 5'-7 'on the "basic constituent layer" 2-4.M using the pigment paint. [V] Manufacturing of a decorative material using a pigment paint when an opaque material that does not allow liquid to permeate is used for the base member. Materials such as metal materials and opaque plastic materials that do not allow liquid to permeate (hereinafter referred to as "opaque smooth surface countermeasure substrate member").
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-requiring base material member is an opaque smooth surface-requiring base material member such as a metal material or an opaque plastic material, the surface of the opaque smooth surface-requiring base material member and the "basic structure" are used. Layer "2-4.M" to form an "adhesion-improving base treatment layer" (also referred to as "adhesion-improving base addition film layer"), and a "basic constituent layer" using a pigment coating
It is necessary to keep good adhesion performance of 4 · M.

The decorative material of the fifth embodiment of the present invention is an embodiment in the case of producing a decorative material provided with this "adhesion improving underlying additional film layer". Naturally, the constitutions of the "basic constituent layers" 2 to 4 · M itself using the pigment paint are the same as those in the case of the first embodiment.

As indicated by the reference numerals in parentheses in FIG. 4, reference numeral 21 denotes an opaque smooth surface-requiring base member 21 made of a metal material or opaque plastic material, and 22 denotes this opaque smooth surface-requiring base member 21. Surface 21a and "basic constituent layer" 2
It is an “adhesion-improving underlayer-added film layer” formed between the polyurethane surfacer layer 2 and the polyurethane surfacer layer 2 of 4 · M. The "adhesion-improving underlying additional film layer" 22 is formed as an underlying adhesion layer using, for example, the following coating material and applied by coating once or twice by, for example, a spraying method [step S21]. [First example] Union Paint Co., Ltd. Product No. 38-67 Product name Mitchaku agent Ingredient name Ingredient amount (wt%) Acrylic resin 10.0% Alcohol solvent 21.0% Ketone solvent 5.0% Ester solvent 13.0% Aromatic hydrocarbon Solvent 45.0% Additive 6.0%

[Second Example] Rock Paint Co., Ltd. Product No. 029-0121 Product name Rock lacquer Mitchachushila Ingredient name Ingredient amount (wt%) Acrylic resin and plasticizer 6.0% Ester and ketone solvent 38.0% Ether ester solvent 9.0% Aromatic hydrocarbon solvent 47.0%

As a result, in the decorative material of the fifth embodiment (FIG. 4), even if the “basic constituent layers” 2 to 4 · M are formed on the smooth surface, the surface 21a of the base member 21 against the smooth surface is required.
Adhesion between the polyurethane surfacer layer 2 and the polyurethane surfacer layer 2 can be ensured satisfactorily, and a beautiful natural wood grain pattern without a phenomenon such as peeling of the coating film layer can be obtained. After that, the "surface-finishing additional film layer" 5-7 or 5'-7 'is formed on the "basic constituent layer" 2-4.M using the pigment paint 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, in the case of applying a natural wood grain pattern M to a transparent smooth surface-necessary countermeasure base member 31 which is a material such as a glass material or a transparent plastic material into which a liquid does not permeate and at least the back surface of which is a smooth surface. Forms a "basic constituent layer for transparent base" (a constituent layer corresponding to "basic constituent layers 2 to 4M") on the back surface (smooth surface) 31a of the transparent base member 31 requiring smooth surface, and is transparent. The natural wood grain pattern M is seen through from the front surface side of the base member 31 which requires a smooth surface.

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" 2-4.M in the first embodiment. The arrangement is the reverse of the arrangement. Further, the back surface finish (corresponding to the surface finish for the first embodiment) of the decorative material to be combined with the "basic constituent layer for transparent substrate" is a mirror finish method using polyurethane. The layer of the back surface finish layer at this time The constitution is also the reverse of the layer constitution in the case of the polyurethane surface finishing method in the first embodiment.

FIG. 5 shows an embodiment in which a "basic constituent layer for transparent underlayer" is formed on the back surface of the transparent base member 31 requiring smooth surface, which is a sixth embodiment of the present invention. is there. In FIG. 5, reference numeral 31 is a transparent smoothness-necessary surface-preventing substrate member 31 made of a glass material or transparent plastic material, and 32 is a back surface 31a of the smoothness-requiring basic substrate member 31.
It is the “adhesion-improving base treatment layer” (also referred to as “adhesion-improving adhesion layer”) formed above.

The paint used for the "adhesion improving adhesion layer" 32 has the same properties as the paint used for the "adhesion improving undercoating layer" 22 of the fifth embodiment (FIG. 4). Paint is selected, for example once to 2 with spraying method
It will be formed by application of a single coating [Step S
31].

The "adhesion-improving adhesion layer" 32 is not particularly excellent in the adhesion performance (peeling resistance), but the location where the coating layer is formed is not damaged by external force. There is no problem because it is the backside of the glass material. It should be noted that the transparent base member 31 for smooth surface required
When the back surface of No. 3 is rubbed to make it rough, the adhesiveness of the coating layer is naturally improved, and in such a case, it is not necessary to particularly form the "adhesion improving adhesion layer" 32.

Reference numeral 33 denotes a polyurethane sanding sealer layer formed on the "adhesion improving adhesion layer" 32 (actually, on the lower side surface). For example, the composition shown in the first or second example below is used. The coating material is diluted with a lacquer thinner as shown below to an extent such that it can be easily applied, and is applied once or several times by, for example, a spraying method. In this case, the number of times of application (film thickness) is determined according to the user's desire or preference for the intended finished surface of the decorative material [step S32].
