Description

  The present invention relates to a method for producing a patterned metal product having a colored pattern on the surface, and a patterned metal product obtained thereby.

  As shown in FIG. 6, a makeup brush such as a face brush is generally caulked by inserting the base portion of a brush needle 2 bundled with brushes 1 into a metal base 3 formed in a cylindrical shape. The base 3 is fixed and attached to the brush shaft 4 integrally.

  Such makeup brushes are required not only for practicality but also for design such as appearance and originality, compared to stationery brushes and paintbrushes. There are many decorative items on the market.

  For example, by providing a core material with a pattern on the inside of a transparent brush shaft 4, a color pattern that is hard to get dirty and rich in change has been proposed (see Patent Document 1).

  On the other hand, since the base 3 is made of metal such as aluminum or brass because the base 3 needs to be caulked and attached, there is not much variation in the decoration method. In general, after an alumite treatment or a chrome plating treatment, a color pattern is provided thereon by printing (baking) such as silk screen printing or hot stamping.

JP 2005-176863 A

  However, the color pattern imparted by printing such as silk screen printing or hot stamping has a problem that when this part is repeatedly touched over a long period of time, the pattern part is gradually peeled off and the pattern part disappears. Further, in the manufacturing process, when the brush head 2 is caulked to the base 3, there is also a problem that the pattern portion tends to be peeled off or damaged at the caulking portion or a portion where a tool or jig for caulking is applied.

  The present invention has been made in view of such circumstances, and it is possible to easily give a beautiful design, a fine design color pattern to the surface of a metal product such as aluminum or brass, and the color pattern is The object is to provide a method for producing an excellent patterned metal product that does not peel off over a long period of time, and to provide a patterned metal product obtained thereby.

  In order to achieve the above object, the present invention provides a step of preparing a base member made of a metal material, a step of forming a colored layer on the surface of the base member, and a metal vapor deposition layer on the surface of the colored layer. A step of partially removing the metal deposition layer by laser irradiation, exposing the colored layer from the removal trace, forming a color pattern, and forming a topcoat layer on the outermost surface. The manufacturing method of the metal product with a pattern is the first gist.

  The present invention also provides a step of preparing a base member made of a metal material, a step of forming a first colored layer on the surface of the base member, and a metal vapor deposition layer on the surface of the first colored layer. A step of forming a second colored layer on the surface of the metal vapor-deposited layer, and the second colored layer and the metal vapor-deposited layer are partially removed by laser irradiation, and the first color is determined from the removal trace. A second gist is a process for producing a patterned metal product comprising a step of exposing a layer to form a color pattern and a step of forming a topcoat layer on the outermost surface.

  Further, the present invention has, as a third gist, a method for producing a patterned metal product in which the metal vapor deposition layer is an indium vapor deposition layer, and the laser irradiation is any of a YAG laser, a YVO4 laser, or a semiconductor laser. The fourth gist is a method for producing a patterned metal product.

  And this invention is a metal product with a pattern obtained by the manufacturing method which is the said 1st summary, Comprising: A colored layer and a metal vapor deposition layer are formed in this order on the surface of the base member which consists of metal materials, The metal deposition layer is partially removed by laser irradiation, and the colored layer is exposed from the removal trace to form a color pattern, and a patterned metal product having a top coat layer formed on the outermost surface It is set as the summary of 5.

  Moreover, this invention is a metal product with a pattern obtained by the manufacturing method which is the said 2nd summary, Comprising: On the surface of the base member which consists of metal materials, a 1st colored layer, a metal vapor deposition layer, and a 2nd colored layer Are formed in this order, and the second colored layer and the metal vapor deposition layer are partially removed by laser irradiation, and the first colored layer is exposed from the removal trace to form a color pattern. The sixth aspect is a patterned metal product having a top coat layer formed on the outermost surface.

  Furthermore, the present invention has, in particular, a patterned metal product in which the metal vapor-deposited layer is an indium vapor-deposited layer as a seventh gist, and the patterned metal product comprises a brush with bundled brushes. An eighth aspect is a patterned metal product that is a base for attaching a metal plate.

  That is, according to the method for producing a patterned metal product which is the first gist of the present invention, a colored layer and a metal vapor deposition layer are formed on the surface of a base member made of a metal material, and then the metal vapor deposition layer is partially irradiated by laser irradiation. Since the color pattern is formed by removing the pattern, it is possible to easily give a beautiful and fine design color pattern only by programming the laser irradiation pattern in the laser apparatus. And since the color pattern is not what was printed, it has the advantage that it does not peel off over a long period of time.

  Moreover, according to the manufacturing method of the patterned metal product which is the second gist of the present invention, the first colored layer and the metal vapor deposition layer are formed in this order on the surface of the base member, and the surface of the metal vapor deposition layer is Further, after forming the second colored layer, the second colored layer and the metal vapor deposition layer are partially removed by laser irradiation to form a color pattern. By contrasting the color with the first colored layer exposed from the removal mark, as well as the above case, it is possible not only to easily give a beautiful design and a fine design color pattern, but also a richer variety of shades Design can be provided.

  Among them, particularly, when the metal vapor deposition layer is an indium vapor deposition layer, the spreadability of the indium vapor deposition layer is good, so that the metal material is caulked or bent after the vapor deposition layer is formed. Even in the case of having a step to perform, it is possible to provide a product having a beautiful color pattern without peeling or cracking in the deposited layer, which is more preferable.

  Further, when the laser irradiation is performed by any of YAG laser, YVO4 laser, or semiconductor laser, the metal vapor deposition layer or the second colored layer and the metal vapor deposition layer are partially removed efficiently and beautifully. This is preferable.

  In addition, in the patterned metal product obtained by the production method of the present invention, the color pattern on the metal surface is not imparted by transfer or printing, but the metal vapor deposition layer or the second colored layer and the metal vapor deposition layer partially. Because it is formed by the removal, it not only gives a beautiful and fine color pattern, but even if it touches and rubs repeatedly, the color pattern will not be lost or lost, It has the advantage of being well maintained.

  In particular, in the patterned metal product, when the metal vapor deposition layer is an indium vapor deposition layer, the spreadability of the indium vapor deposition layer is good. Even if it passes through the process to do, since the vapor deposition layer does not peel or crack and a beautiful color pattern is maintained, it is more suitable.

  Furthermore, in particular, when the metal product with a pattern is a base for attaching a brush needle bundled with brushes, the color pattern applied to the surface of the base is highly durable. It is not particularly damaged by the caulking process or worn by repeated use, and can maintain a beautiful state for a long time.

It is explanatory drawing of the base member used for the manufacturing method of the said nozzle | cap | die. (A)-(c) is explanatory drawing of the manufacturing method of the said nozzle | cap | die all. (A), (b) is explanatory drawing of the manufacturing method of the said nozzle | cap | die both. (A)-(d) is explanatory drawing of the manufacturing method of a nozzle | cap | die which is another Example of this invention. It is a perspective view which shows an example of a common makeup brush.

  Next, an embodiment for carrying out the present invention will be described.

  FIG. 1 shows a perspective view of a makeup brush using a base 10 according to an embodiment of the present invention. The surface of the base 10 has a metallic luster color with a pink background, and a black fine color pattern 11 is provided on a part thereof. The other configuration is the same as that of the makeup brush shown in FIG. 6, and the same parts are denoted by the same reference numerals and description thereof is omitted.

  The base 10 can be manufactured, for example, as follows. That is, first, a base member 10a as shown in FIG. 2 is prepared by shaping an aluminum material (thickness 0.2 mm) into a substantially cylindrical base shape. And as shown to Fig.3 (a), the black 1st colored layer 12 (thickness 20 micrometers) is formed in the whole outer peripheral surface by carrying out black alumite coating which serves as protection and coloring of aluminum cloth | dough. To do.

  Next, as shown in FIG. 3B, a metal vapor deposition layer 13 made of an indium layer having a thickness of 0.04 μm is formed on the entire surface of the first colored layer 12 by indium vapor deposition. The second colored layer 14 (thickness: 15 μm) is formed by applying a pink transparent coloring paint to form a cured film, as shown in FIG. Since the transparent colored paint is pink, the formation of the second colored layer 14 makes the inorganic metallic luster color of the metal vapor-deposited layer 13 appear to be a slightly pinkish luster color.

  Next, as shown in FIG. 4A, laser irradiation with a YAG laser is performed on a predetermined color pattern formation scheduled portion of the surface of the second colored layer 14, and the second portion of the irradiated portion is irradiated. The colored layer 14 and the metal vapor deposition layer 13 are removed, and the first colored layer 12 is exposed from the removal trace. The exposed portion 12a of the first colored layer 12 is black, and a color pattern 11 (see FIG. 1) appears by contrast with the surface color (pinkish metallic luster color) that has not been removed. .

  And as shown in FIG.4 (b), the target nozzle | cap | die is formed by forming the colorless and transparent urethane-type topcoat layer 15 in the outermost surface in which the said color pattern 11 was formed, and protecting the whole surface. 10 can be obtained.

  Therefore, the base part of the brush head 2 in which the brush 1 is bundled is fixed by inserting into the base 10 and caulking, and the base 10 is attached to the brush shaft 4 integrally, and the makeup brush shown in FIG. Can be obtained.

  According to the base 10 of the makeup brush, since the metal vapor deposition layer 13 is formed of an indium vapor deposition layer having excellent spreadability, the caulking process for fixing the brush ear 2 is performed after the vapor deposition layer is formed. However, the metal vapor deposition layer 13 is not peeled off or broken, and as a result, the color pattern 11 is maintained in a beautiful state. In addition, the portion of the base 10 is touched by fingers or in contact with other objects every time the use of the makeup brush is repeated, but since the durability of the color pattern 11 is excellent, it can be used repeatedly. Can maintain a beautiful state for a long time.

  In the manufacturing method of the base 10, the material of the base member 10 a is not limited to aluminum, and examples thereof include brass, stainless steel, nickel, and an aluminum-nickel alloy. However, it is preferable to use aluminum or brass from the viewpoint of lightness of material and ease of molding. And the thickness depends on the type and use of the product, but when applied to a makeup brush base, similar cosmetic accessories, portable accessories, etc., 0.1 to 2 mm from the viewpoint of weight reduction and handling strength. It is preferable to set.

  In addition, when the base member 10a is made of aluminum, the first colored layer 12 formed on the outer peripheral surface of the base member 10a has an extra coloring step if it is colored simultaneously with the alumite treatment as in the above example. The colored layer 12 may be separately formed by various plating processes, baking coating processes, or the like after the alumite process. And although the color and thickness of the colored layer 12 can be appropriately set according to the purpose, considering the weight reduction of the obtained product and the adhesiveness with the metal vapor deposition layer 13, the thickness is It is preferable that it is 20 μm or less.

  Further, in the above example, an indium vapor deposition layer is used as the metal vapor deposition layer 13 formed on the surface of the first colored layer 12, but other examples of the metal to be vapor deposited include tin and stainless steel. . However, when processing such as caulking or bending is performed after decoration, it is optimal to use indium from the viewpoint of processing followability.

  And the thickness of the said metal vapor deposition layer 13 can be suitably set according to the kind of the metal, the use of a metal product, a magnitude | size, etc., but weight reduction of the product obtained and said 1st colored layer In view of adhesiveness to No. 12, processing follow-up properties such as caulking, and the appearance of metallic luster, it is preferable to set to 0.001 to 0.08 μm. That is, if it is too thin than the above range, it is difficult to obtain a metallic luster color. Conversely, if it is too thick, the adhesion to the first colored layer 12 and the lightness are impaired, and the processing followability deteriorates. Because there is a fear.

  In the above example, as the second colored layer 14 formed on the surface of the metal vapor-deposited layer 13, a cured film made of a pink transparent colored paint is used. However, a colorant composition for forming the colored layer 14 is used. As the product, for example, various thermosetting coating compositions used for metal undercoating and intermediate coating are used. The paint can be blended with colorants for imparting various colors such as dyes and pigments, but dare to use a colorless and transparent paint composition that does not contain these colorants, and a metal vapor deposition layer. You may make it show 13 metallic luster colors as it is. Also in this case, the colorless and transparent coating layer becomes the colored layer 14.

  And although the thickness of the said 2nd colored layer 14 can also be set suitably, if the weight reduction of the product obtained and the adhesiveness with the metal vapor deposition layer 13 are considered, the thickness will be 5-5. It is suitable that it is 50 micrometers.

  Furthermore, in the above example, a YAG laser was used as the laser irradiation for removing the second colored layer 14 and the metal deposition layer 13, but instead, a carbon dioxide laser, a ruby laser, a YVO4 laser, Various laser devices such as a semiconductor laser can be used. Among these, in terms of controllability and finish, it is preferable to use any one of YAG laser, YVO4 laser, and semiconductor laser.

  In the above example, the outermost topcoat layer 15 is formed of a colorless and transparent urethane-based topcoat paint, but other topcoat paints can be used instead. The top coat layer 15 is intended to prevent the metal portion from rusting due to contact with moisture, and to protect the color pattern 11 formed by laser irradiation, so that the color pattern 11 can be clearly seen. Is preferably colorless and transparent, but may be slightly colored by a colorant as long as it is transparent (or translucent) so that the color pattern 11 can be seen through.

  The thickness of the top coat layer 15 can also be set as appropriate, but considering the weight reduction of the product to be obtained and the protective strength to the product surface, the thickness is preferably 10 to 50 μm. It is.

  In the above example, the second colored layer 14 is formed on the surface of the metal vapor-deposited layer 13 using a pink transparent colored paint, and the metallic gloss color of the metal vapor-deposited layer 13 is given a pink tone. The second colored layer 14 is not always necessary. In that case, for example, as shown in FIGS. 5A and 5B, the colored layer 12 and the metal vapor deposition layer 13 are formed in this order on the surface of the base member 10a in the same manner as in the above example. After that, as shown in FIG. 5C, the color pattern 11 is formed by performing laser irradiation from above. And the nozzle | cap | die 10 with the color pattern 11 can be obtained by forming the topcoat layer 15 in the outermost surface.

  In this, since the second colored layer 14 is not formed, the color pattern 11 seen through the top coat layer 15 is formed by a combination of the surface color of the metal vapor-deposited layer 13 and the first colored layer 12. However, the same effect as the above example can be obtained.

  In these examples, the present invention is applied to the base 10 of the makeup brush. However, the present invention is applied to various metal products having a color pattern 11 on the surface of a metal base member. Can do. In particular, since the color pattern 11 does not disappear even if it repeatedly touches the hand or receives friction, it is preferable to apply it to a metal product that easily touches or receives friction. And since the thing using an indium vapor deposition layer as the metal vapor deposition layer 13 is excellent in the spreading property of a vapor deposition layer, and is hard to be damaged even if it processes by crimping, a bending, etc. in a manufacturing process, it is especially after color pattern 11 formation. It is preferable to apply to a metal product having such a processing step. Therefore, the present invention can be applied to, for example, various brush caps, accessory products such as rings, metal containers such as glasses cases and tea tubes, interior products such as lighting covers, etc. It is preferable to use it.

  Next, examples of the present invention will be described together with comparative examples. However, the present invention is not limited to the following examples.

[Example 1]
In order to obtain a base for a makeup brush, an aluminum base member having a thickness of 0.2 mm and having a base shape was prepared. Next, black alumite coating was performed to form a first colored layer (black) having a thickness of 20 μm, and indium vapor deposition was further performed on the surface to form a metal vapor deposition layer having a thickness of 0.04 μm. Next, a transparent colored paint was applied to the surface to form a second colored layer (transparent pink color) having a thickness of 15 μm. Then, laser irradiation is performed by the YAG laser device from above, and only the second colored layer and the metal vapor deposition layer in the preset color pattern formation scheduled portion are removed, and the first trace below the removed trace is removed. The colored layer was exposed to reveal a black pattern portion. Then, a top coat layer (urethane-based top coat) having a thickness of 15 μm was formed thereon to obtain a target base with a color pattern.

[Example 2]
The second colored layer was not formed. Other than that was carried out similarly to the said Example 1, and obtained the nozzle | cap | die with the target color pattern.

[Comparative Example 1]
An aluminum base member similar to that in Example 1 was anodized without being colored. And the color pattern layer (thickness 30 micrometers) was formed by printing and baking a color pattern on the surface using a black coloring paint, and the die with the target color pattern was obtained.

  Using a rubbing tester (friction tester, manufactured by Daiei Kagaku Seisakusho Co., Ltd.) on the color pattern forming surfaces of Examples 1 and 2 and Comparative Example 1 above, a load of 0.5 N was applied from the top with wool felt. However, the sliding motion by 100,000 reciprocations was repeated, and the change in the color pattern portion was observed.

  As a result, the products of Examples 1 and 2 had no change in color pattern even after 100,000 sliding operations, but the product of Comparative Example 1 had an end to the color pattern after about 20,000 times. Most of the color pattern disappeared after 100,000 times of sliding operation. Therefore, it can be seen that Examples 1 and 2 have very high durability of the color pattern portion.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a method for producing a patterned metal product that gives a color pattern with excellent durability to the surface of a metal product that is repeatedly touched or subject to friction, and the patterned metal product obtained thereby. it can.
