Description

The present invention relates to a design coating film, a method for forming the same, and a coated article.

A coating film is formed on the surface of many articles such as various industrial products, building materials, and large structures for the purpose of surface protection and design. When imparting design properties to the surface of an article with such a coating film, in addition to blending various components in the paint, many attempts have been made to obtain a unique appearance by processing the coating film itself. .

One example of such a design coating film is a coating film having irregularities formed on the coating film surface. As such a coating film, for example, a film in which a concavo-convex pattern is formed on the coating film surface by pressing a design roller on which the concavo-convex pattern is formed is known (for example, see Patent Document 1). .

Such a concavo-convex pattern has a three-dimensional design that cannot be obtained with a smooth coating film by forming concavo-convex patterns with large pitches on the coating film surface and visually recognizing the concavo-convex pattern generated by the concavo-convex pattern. It is what.

However, in recent years, with the diversification of consumer preferences, the importance of designs for consumers to select products is increasing. For this reason, the coating film which has a new external appearance different from such a simple uneven | corrugated pattern is desired. Patent Document 1 does not describe a coating film forming method for obtaining a coating film having a design different from such a simple uneven pattern.
JP 2000-33332 A

In view of the above-mentioned present situation, the present invention provides a design coating film having a unique appearance that has not been able to be formed by painting until now and having excellent design properties, a method for forming the same, and a coated article. It is for the purpose.

The present invention is a design coating film characterized by having a coating layer having a metallic luster and an embossed surface that causes anisotropy of light reflection.
The embossed surface preferably has a concavo-convex structure with an emboss width of 20 to 1000 (line / inch).

The present invention includes a step (1) of applying a paint containing a metal pigment to an article to be coated, a step (2) of partially curing the coating film formed by the above step (1), and the above step A step (3) of performing an embossing process for causing light reflection anisotropy in the semi-cured coating film formed in the step (2), and a coating film having the embossing formed in the step (3) are cured. It is also a method for forming the above-described designable coating film characterized by comprising the step (4).

In the above-described method for forming a design coating film, it is formed by the step (5-1) for forming a clear coating film on the coating film formed by the step (4) and the step (5-1). It may have a step (5-2) of curing the coated film.

The present invention includes a step (1-1) of applying a paint containing a metal pigment to an object to be coated, a step (1-2) of curing a coating film formed by the above step (1-1), and the above step ( The step (1-3) of forming a clear coating film on the coating film formed by 1-2), and the step of partially curing the coating film formed by the above step (1-3) to form a semi-cured coating film (2) The step (3) of performing an embossing process that causes the light-reflective anisotropy to the semi-cured coating film formed by the step (2), and the coating film formed by the step (3) It is also a method for forming the above-described design coating film characterized by comprising a curing step (4).

The embossing is preferably performed by a roll having an embossing mold.
The step (1) or the step (1-1) may be performed on an object to be coated with primer.
The paint containing the metal pigment is preferably a thermosetting paint.
The object to be coated is preferably a metal plate.

The present invention is also a coated article characterized by having the above-described designable coating film.
Hereinafter, the present invention will be described in detail.

The object of the present invention is to form a coating film having a new design that has never been achieved by the action of a coating layer having a metallic luster and an embossed surface that causes anisotropy of light reflection. is there. That is, a new design that has never been achieved can be obtained by the light reflection performance of the coating layer having a metallic luster and the anisotropy of light reflection caused by the embossed surface.

As will be described below with reference to the drawings, an embossed surface that causes anisotropy of light reflection has a property of causing characteristic light reflection on the surface. On the other hand, a coating film having a metallic luster has a unique appearance that causes metallic light reflection. By the interaction of these special properties relating to light reflection, light reflection becomes more and more complex, and the coating film of the present invention has an unprecedented and beautiful appearance. That is, the coating film which has the new design which is not in the past based on the effect | action which combined these two elements is obtained.

The effect | action which the designable coating film of this invention has such a new designability is demonstrated still in detail based on FIGS. FIG. 1 shows an example of a coating film on which embossing is formed. In FIG. 1, continuous and linear embossing is formed in the vertical direction in the drawing. Although FIG. 1 is an enlarged view and the emboss is described so that it can be visually recognized, in reality, this emboss is a fine unevenness, and each unevenness is recognized as a line drawing. As a result, designability is not obtained. As shown in FIGS. 8 and 9, the surface of the coating film of the present invention obtained by Examples was scanned with a scanner. Although the actual size shown in FIG. 8 cannot visually recognize the unevenness, it can be seen that the unevenness can be recognized in FIG.

And when light is applied to the coating film from the light source 1 and the coating film is viewed from the observation point 1, and when the coating film is irradiated from the light source 2 to the coating film and viewed from the observation point 2 Compare. In these two cases, there is no difference except that the position of the light source and the position of the observation point are the vertical direction or the horizontal direction with respect to the continuous direction of the emboss.

2 and 3 are cross-sectional views of the cross-section 1 and the cross-section 2 of FIG. 1, and the case where light is incident in this direction is illustrated.

Since the coating film of the present invention has a coating layer having a metallic luster, the coating layer has a property of reflecting light. This reflection is greatly affected by the uneven shape formed on the surface of the coating film. However, there are reflection elements as shown in FIG. 2 and reflection elements as shown in FIG. So there is a total reflection. When light is emitted from the light source 1 and the coating surface is observed from the observation point 1, the reflection element as shown in FIG. 2 is recognized as a reflection element in the vertical direction, and the reflection element as shown in FIG. Is recognized as a reflective element in the horizontal direction. On the other hand, when irradiating light from the light source 2 and observing from the observation point 2, the vertical and horizontal sides of each element are recognized in reverse.

For this reason, in these two cases, the reflection state of light is completely different, and it is recognized as a visually completely different appearance. Thus, in this specification, embossing that provides a state that can be recognized as a visually different appearance due to the difference between the light source position and the observation point is referred to as “anisotropy of light reflection”. "Embossing to be generated". In addition, if the uneven | corrugated width is too large, it will be visually observed as a mere unevenness | corrugation and will not be observed as anisotropy of light reflection. If the width of the unevenness is too small, a light diffraction phenomenon occurs, and the pattern is observed as a rainbow-colored design, which may be different from the object of the present invention.

A picture, a continuous pattern, or the like can be formed on the coating film by using an emboss that causes such light reflection anisotropy. The pictures and continuous patterns formed in this way are completely different from those drawn by simple uneven patterns or color painting, and have a unique appearance due to the reflection state of the surface being different depending on the viewing direction. is there.

An example of such a coating film of the present invention is shown in FIG. In the coating film shown in FIG. 4, it is cut into nine rectangular portions, each having a continuous embossment with irregularities in different directions. Since these all have anisotropy of light reflection, the light reflection state is recognized differently depending on the viewing direction. Since the nine portions have different embossing directions, the respective portions are recognized as visually different. And, as the viewing angle changes, it has a unique design property that the visual effect changes.

The embossing that causes the light reflection anisotropy may be a straight line or a curve formed substantially in parallel with a certain width, or a point group arranged to cause the light reflection anisotropy. preferable. Here, the point group arranged so as to cause anisotropy of light reflection is, for example, a point group, but is not a point arranged in a completely uniform state, but the points are substantially parallel to each other. Examples thereof include those arranged so as to have the same properties as the formed straight lines or curves. More specifically, a straight line or a curved line formed with a constant width and substantially parallel may be formed by a broken line.

The embossing is preferably formed with an embossing width of 20 to 1000 line / inch. By being formed with the emboss width, it is possible to obtain good light reflection anisotropy. If it is less than 20 lines / inch, a rough concavo-convex pattern is formed, so that sufficient light reflection anisotropy may not be obtained. If it exceeds 1000 lines / inch, fine processing becomes extremely difficult, and it may be difficult to produce stably. The embossing is preferably 40 to 800 line / inch, and more preferably 60 to 600 line / inch. Here, “line / inch” is the number of lines formed by the formation of irregularities per inch, and can be counted by a method such as enlarging the surface of the coating film with a magnifying glass or the like. For example, when the surface of the coating film is magnified 6 times, it becomes as shown in FIG. 9 and thus can be directly counted.

The embossing preferably has a depth of 1 to 100 μm. If it is less than 1 μm, the anisotropy of light reflection becomes weak, and an excellent design property may not be obtained. If it exceeds 100 μm, there may be a problem that workability is difficult. The depth is more preferably in the range of 1 to 30 μm, and still more preferably in the range of 3 to 10 μm.

The present invention has a coating layer having a metallic luster. As the coating film having a metallic luster, a known coating having a metallic appearance can be used, and can be formed by a paint containing a pigment. Any pigment may be used as the pigment as long as it can exhibit a metallic luster. Among these, metal pigments can be mentioned as preferable pigments. In the present specification, the “metal pigment” refers to a pigment having high reflectivity and having a metallic luster, and is not limited to a pigment formed of a metal, such as glass flakes. It also includes a pigment coated with a metal by a method such as vapor deposition on a substrate.

The metal pigment is not particularly limited. For example, aluminum flake pigment, metal oxide-coated alumina flake pigment, metal oxide-coated silica flake pigment, graphite pigment, bronze powder, tin foil, gold foil, plastic-coated metal pigment, phthalocyanine flake Pigment, interference mica pigment, colored mica pigment, metallic titanium flake pigment, stainless steel flake pigment, plate-like iron oxide pigment, metal-plated glass flake pigment, metal oxide-coated plated glass flake pigment, hologram pigment, multilayer thin film structure of metal reflective layer And flake pigments made of cholesteric liquid crystal polymer. Two or more of these may be used simultaneously. Among these, a pigment made of aluminum metal is preferable because it can be easily blended in the paint.

The pigment made of the aluminum metal is not particularly limited, and examples thereof include aluminum powder and aluminum foil. As said aluminum, what becomes an average particle diameter in the range of 3-50 micrometers is preferable. When the average particle diameter is less than the lower limit, the dispersion state in the coating film is deteriorated and the function expression is reduced. If the average particle diameter exceeds the upper limit, it is not preferable because it is necessary to increase the aluminum content.

It does not specifically limit as said aluminum, Commercial products, such as Asahi Kasei Co., Ltd. aluminum paste, Toyo Aluminum Co., Ltd. Alpaste (brand name), can also be used.

The stainless steel is not particularly limited, and examples thereof include flakes and spheres. It does not specifically limit as said flaky stainless steel, For example, commercial products, such as Toyo Aluminum Co., Ltd. stainless steel paste (brand name), can be used.

It is preferable that content of the said metal pigment exists in the range of 0.1-30 mass% with respect to coating-film solid content. If the content is less than 0.1% by mass, the coating film may be squeezed and sufficient reflectivity may not be obtained, and the intended designability may not be obtained. When the content exceeds 30% by mass, it is difficult to form a paint and the metal pigment may not be retained in the coating film. The content is more preferably in the range of 1 to 10% by mass.

The coating film containing the metal pigment is an organic resin, pigment, curing agent, antifoaming agent, anti-settling agent, ultraviolet absorber, antioxidant, leveling agent, surface conditioner, anti-sagging agent in addition to the metal pigment. Ingredients usually used for forming a coating film, such as a thickener, a lubricant, and a crosslinkable polymer particle, can be used. The resin is not particularly limited, and examples thereof include acrylic resins, alkyd resins, polyester resins, epoxy resins, urethane resins, polycarbonate resins, fluororesins, silicate resins, chlorinated resins, polyolefin resins, and modified resins thereof. be able to.

The pigment is not particularly limited, and examples thereof include organic azo lake pigments, insoluble azo pigments, condensed azo pigments, phthalocyanine pigments, indigo pigments, perinone pigments, perylene pigments, quinophthalone pigments, dioxazines. Pigments, quinacridone pigments, isoindolinone pigments, metal complex pigments, inorganic chrome yellow, yellow iron oxide, red iron oxide, titanium dioxide, carbon black, etc., and as extender pigments, calcium carbonate, barium sulfate, Examples include clay and talc.

More specifically, the specific embodiment of the coating film having a metallic luster as described above and an embossed surface that causes anisotropy of light reflection is, for example, the following 2 Examples of types can be mentioned. In the first aspect, the surface of the coating film having a metallic luster has an embossed surface that causes light reflection anisotropy, as shown in FIGS. 5 and 6. In this case, since the coating film having a metallic luster has embossing, complicated light reflection occurs, and specific design properties can be obtained. As shown in FIG. 6, even if a clear coating layer is further provided, the same complicated light reflection occurs and a specific design is obtained.

In the second embodiment, the embossed surface causing the light reflection anisotropy is formed in a coating film different from the coating film having a metallic luster. More specifically, as shown in FIG. 7, a metallic coating having a clear coating layer having an embossed surface that causes anisotropy of light reflection on the coating layer can be mentioned. Even in such an embodiment, it has a specific design by the combination of metallic luster and light reflection anisotropy. The coating film according to the first aspect and the coating film according to the second aspect have slightly different appearances, and these can be properly used according to the intended application.

The design coating film as described above can be formed, for example, by the following method. The method for forming a designable coating film shown below is also a part of the present invention.

The design coating film according to the first aspect includes a step (1) of applying a paint containing a metal pigment to an object to be coated, a partially cured coating film formed by the step (1), and a semi-cured coating film. Formed by the step (2), the step (3) of embossing the semi-cured coating film formed by the step (2) to cause light reflection anisotropy, and the step (3). It can form by the process (4) of hardening the coating film which has emboss (Hereafter, this is described as the 1st coating-film formation method).

Step (1) in the first coating film forming method is a step of applying a paint containing a metal pigment to an object to be coated. As the paint for forming the coating film, for example, a known paint containing the binder resin as described above can be used, and any form of paint such as water-based paint, solvent-based paint, and powder paint can be used. Can be used.

The coating material containing the metal pigment needs to have curability. Sufficient coating film properties can be obtained by having curability. The curability may be room temperature curable, thermosetting, energy ray curable (for example, ultraviolet curable, etc.), or a paint having these properties. From the viewpoint of ease of process control, etc., a thermosetting paint is preferred.

The curing system for the paint containing the metal pigment is not particularly limited, and any curing system such as a melamine curing system or an isocyanate curing system can be used.

The paint containing the metal pigment may be a commercially available one. For example, Nippe Super Coat 360HQ (manufactured by Nippon Fine Coatings Co., Ltd.) can be used.

The paint containing the metal pigment is preferably applied at a coating amount of 3 to 300 g / m ² (in terms of solid content). If it is 3 g / m ² or less, the concealing effect by the metal pigment may be insufficient, or embossing may not be formed satisfactorily. Even if the coating is performed at a coating amount exceeding 300 g / m ² , the effect is not good, which is economically disadvantageous.

The paint containing the metal pigment may be applied in the form of an object to which a primer is applied depending on the properties of the object to be coated. The primer coating is not particularly limited, and examples thereof include coating with known primers such as acrylic, acrylic emulsion, epoxy, urethane, polyisocyanate, sodium silicate, and the like. Either may be sufficient.

Step (2) is a step of partially curing the coating film formed in the above step (1) to form a semi-cured coating film. That is, it is a step in which the surface of the coating film is partially cured by performing heat, energy ray irradiation, or the like, so that the embossing that causes the above-described light reflection anisotropy can be performed.

When embossing is applied to an uncured coating film, it will be embossed in a state where the resin fluidity has not completely disappeared. Cannot be maintained, and a coating film having good design properties cannot be formed. Moreover, since the coating film in a completely cured state does not have processability, it is extremely difficult to perform emboss formation. Therefore, good embossing can be performed by partially curing the coating film in the step (2) to make it a semi-cured state and then performing embossing.

The semi-cured coating film refers to a coating film in a state where the curing reaction has progressed to such an extent that the coating film surface can form embossing, and the composition, properties, method of embossing, and embossing conditions of the coating It is preferable to carry out by finding the curing conditions while adjusting the curing conditions as necessary. In particular, in the case of curing by thermosetting, when the resin is heated again by the following step (4), the fluidity of the resin is temporarily increased, so that the uneven shape formed by the step (3) may not be maintained. is there. Therefore, in this case, the partial curing in the above step (2) indicates a cured state that does not cause such a problem.

That is, the coating material to be used is semi-cured under various conditions, and then the steps (3) and (4) described in detail below are performed to find and observe the conditions under which a good embossed surface is formed. Suitable processing conditions of the step (2) can be found based on the applied coating conditions.

For example, as a coating film on which an embossed surface is applied, a polyester resin / melamine resin as described in the examples is applied at 20 g / m ² and a confirmation test of curing conditions is actually performed when embossing is performed by metal roll pressing. The results obtained in FIG. FIG. 10 shows that good curing can be performed within a range sandwiched between two graphs with time as the horizontal axis and curing temperature as the vertical axis. If such a graph is created for the paint that forms the coating film that forms the embossed surface, curing conditions can be set according to the graph to form a suitable emboss.

For example, when the colored coating layer on which the embossed surface is applied is 20 g / m ² and embossing by metal roll pressing is performed, the processing conditions of step (2) were determined by the above experiment. It became clear that the condition of seconds was appropriate.

The step (3) is a step of embossing that causes the light-reflective anisotropy to occur in the semi-cured coating film formed in the step (2). That is, it is a process for forming an embossed shape that is essential for obtaining the effect in the designable coating film of the present invention as described above.

The embossing method is not particularly limited, and a method of forming a desired uneven shape on the surface by pressing a roll having the desired uneven shape on the surface onto the semi-cured coating film. The method etc. which are formed by pressure bonding, such as a press, on the semi-cured coating film can be mentioned.

The roll having the irregularities formed on the surface can be made of any material such as metal, rubber or resin, and the irregularities can be formed on the roll by a known processing method. .

Specifically, as the method of the above step (3), for example, when the object to be coated has a continuous shape such as a metal plate, a processing step using an embossing roll is provided on the line. It is preferable in that it can be continuously produced.

A process (4) is a process of hardening the coating film which performed the said process (3). That is, since the step (2) is a step of partial curing to such a degree that the step (3) can be performed, in order to obtain good coating film properties, by performing the curing again after forming the emboss. It is necessary to cure the coating film. The curing method is not particularly limited, and examples thereof include heat irradiation and energy ray irradiation.

The first coating film forming method may include a step of forming a clear coating film layer by applying the clear coating composition after performing the step (4). By forming the clear coating layer, it is possible to prevent the embossed unevenness from being worn and to obtain a coating having excellent durability. Such a coating film is formed by the step (5-1) of forming a clear coating film and the step (5-2) of curing the coating film formed by the above step (5-1). It is preferable.

The clear coating that can be used in the step (5-1) is not particularly limited, and examples thereof include acrylic resins, alkyd resins, polyester resins, epoxy resins, urethane resins, polycarbonate resins, fluororesins, silicate resins, and chlorine-based resins. Examples thereof include clear paints containing resins, polyolefin resins, and modified resins thereof. In addition, any form of paint such as water-based paint, solvent-based paint, and powder paint can be used.

The curing conditions in the above step (5-2) are not particularly limited, and can be carried out by selecting suitable conditions according to the type of clear paint to be used.

The design coating film of the second aspect includes a step (1-1) of applying a paint containing a metal pigment to an object to be coated, and a step of curing the coating film formed by the step (1-1) ( 1-2), the step (1-3) of forming a clear coating film on the coating film formed in the step (1-2), and the coating film formed in the step (1-3) is partially cured. A step (2) for forming a semi-cured coating film, a step (3) for embossing the semi-cured coating film formed by the step (2) to cause anisotropy of light reflection, and the step (3) ) Can be formed by the step (4) of curing the coating film formed (hereinafter referred to as a second coating film forming method).

In the second coating film forming method, steps (1-1) and steps (2) to (4) are performed in the same manner as steps (1) to (4) in the first coating film forming method. The same paint can be used.

The said process (1-2) is a process of hardening the coating film containing the metal pigment formed by the process (1-1), and can be performed on desired hardening conditions according to the kind of coating material to be used. When the step (1-3) of applying the clear paint is performed without performing the above step (1-2), the metallic luster deteriorates due to the disorder of the arrangement of the metal pigment in the coating film containing the metal pigment. There is a fear.

The step (1-3) is a step of forming a clear coating film, and can be performed by applying a normal clear coating. The clear paint that can be used is not particularly limited. For example, acrylic resin, alkyd resin, polyester resin, epoxy resin, urethane resin, polycarbonate resin, fluororesin, silicate resin, chlorine resin, polyolefin resin, and Examples thereof include clear paints containing these modified resins. In addition, any form of paint such as water-based paint, solvent-based paint, and powder paint can be used.

The method for forming a design coating film according to the present invention includes a galvanized steel plate, a zinc / aluminum alloy plated steel plate, an aluminum / zinc alloy plated steel plate, a zinc / iron alloy plated steel plate, an aluminum plated steel plate, an aluminum plate, or a stainless steel plate. Board; ceramics base material such as slate, cement, calcium silicate board, wood piece cement board; ceramics, glass, plastic, wood, stone, concrete, fiber, fabric, paper, those consisting of a plurality of base materials among these, The present invention can be applied to coating of any material such as a laminate, an elastic waterproof film, or a seal. Especially, the raw material which has planarity like a metal plate, a plastics etc. is preferable from the point which can form a fine unevenness | corrugation suitably with a roll.

A coated article formed with the above-described designable coating film is also one aspect of the present invention. The coated article is not particularly limited, and examples thereof include building materials, interior goods, electrical products, and automobile parts.

According to the present invention, a coating film having a new design that has never been obtained can be obtained by the action of a coating layer having a metallic luster and an embossed surface that causes anisotropy of light reflection. That is, a new design that has never been obtained was obtained by the light reflection performance of the coating layer having a metallic luster and the anisotropy of light reflection caused by the embossed surface.

The embossed surface that causes anisotropy of light reflection has a property of causing characteristic light reflection on the surface. On the other hand, a coating film containing a metal pigment has a metal-like unique appearance due to reflection of light by the metal pigment. Due to the interaction of these special properties relating to light reflection, the coating film of the present invention has an unprecedented and beautiful appearance.
