Description
本発明は、レーザー加飾方法に関するものである。 The present invention relates to a laser decoration method.
表面に塗膜が形成された金属基材に対して、レーザー光を照射してマーキング等の加飾を行うことが、各種の製品に対して行われており、一つの従来技術としては、金属基材の表面に形成される膜を厚膜として、レーザー光を照射した場合に、厚膜を金属基材の表面に達しない深さまで除去してマーキングを行う技術が知られている（下記特許文献１参照）。 Various products are decorated by irradiating a metal substrate having a coating film formed on the surface with laser light for marking and the like. A technique is known in which a film formed on the surface of a base material is used as a thick film, and when laser light is irradiated, the thick film is removed to a depth that does not reach the surface of the metal base material for marking (the following patent). See Document 1).
また、他の従来技術としては、表面処理が行われた金属基材の上に光を透過し得る塗膜を形成し、塗膜上にレーザー光を照射して、塗膜と金属基材との対向部分に変色層を形成する技術が知られている（下記特許文献２参照）。 Further, as another conventional technique, a coating film capable of transmitting light is formed on a surface-treated metal substrate, and a laser beam is irradiated on the coating film to form a coating film and the metal substrate. A technique for forming a discoloration layer on the opposite portion of the light is known (see Patent Document 2 below).
前述した前者の従来技術は、塗膜の膜厚を厚くする必要があり、照射するレーザー光の強度を微妙に調整する必要があるので、缶容器の外表面に形成された塗膜層への加飾などには適用し難い。また、前述した後者の従来技術は、塗膜が透明層に限られるので、様々な色で着色された塗膜層に対しての加飾には適用できない。 In the former prior art described above, it is necessary to increase the film thickness of the coating film, and it is necessary to finely adjust the intensity of the laser beam to be irradiated. Therefore, the coating film layer formed on the outer surface of the can container is applied. It is difficult to apply to decorations. Further, the latter conventional technique described above cannot be applied to decoration of a coating film layer colored with various colors because the coating film is limited to a transparent layer.
また、缶容器等の金属製品における金属基材はアルミニウム基材であり、表面処理層を形成した上に塗膜層が形成されている。この塗膜層にレーザー光を照射してマーキング等の加飾を行った場合、レーザー光の照射位置で塗膜層が除去され、更に、表面処理層が除去されてアルミニウム基材が表面に露出するケースが多い。このような状態になると、その後に熱水殺菌処理などを行った場合に、露出したアルミニウム基材の表面が黒色に変色（以下、黒変）することが確認されており、これによって加飾の視認性が低下することが問題になっていた。 Further, the metal base material in a metal product such as a can container is an aluminum base material, and a coating film layer is formed on the surface treatment layer. When this coating film layer is irradiated with laser light to decorate it with markings or the like, the coating film layer is removed at the irradiation position of the laser light, and further, the surface treatment layer is removed to expose the aluminum base material to the surface. In many cases. In such a state, it has been confirmed that the surface of the exposed aluminum base material turns black (hereinafter referred to as blackening) when hot water sterilization treatment is performed thereafter, and this causes decoration. The problem was that visibility was reduced.
本発明は、このような問題に対処することを課題としている。すなわち、缶容器等のアルミニウム基材の表面に、表面処理層を介して塗膜層を形成し、塗膜層にレーザー光を照射して加飾を施すレーザー加飾方法において、露出したアルミニウム基材の黒変を抑止することで、加飾の視認性を高めること、などが本発明の課題である。 An object of the present invention is to deal with such a problem. That is, in a laser decoration method in which a coating film layer is formed on the surface of an aluminum base material such as a can container via a surface treatment layer and the coating film layer is irradiated with laser light to decorate the coating film layer, the exposed aluminum group is used. It is an object of the present invention to improve the visibility of decoration by suppressing blackening of the material.
このような課題を解決するために、本発明は、以下の構成を具備する。
アルミニウム基材の表面に、表面処理層を介して塗膜層を形成し、前記塗膜層にレーザー光を照射して加飾を施すレーザー加飾方法において、前記レーザー光の照射位置における前記塗膜層の色を、前記レーザー光の波長の吸収率が高い色に設定することを特徴とするレーザー加飾方法。
In order to solve such a problem, the present invention includes the following configurations.
In a laser decoration method in which a coating film layer is formed on the surface of an aluminum base material via a surface treatment layer and the coating film layer is irradiated with laser light to decorate the surface, the coating at the irradiation position of the laser beam is performed. A laser decoration method characterized in that the color of the film layer is set to a color having a high absorption rate of the wavelength of the laser light.
このような特徴を有する本発明のレーザー加飾方法によると、レーザー光の照射によって加飾された部分の黒変を抑止することができ、加飾の視認性を高めることができる。 According to the laser decoration method of the present invention having such characteristics, it is possible to suppress blackening of the decorated portion by irradiation with laser light, and it is possible to improve the visibility of the decoration.
以下、図面を参照して本発明の実施形態を説明する。本発明の実施形態は、図１に示すように、アルミニウム基材Ｌ３の表面に表面処理層Ｌ２を形成し、更にその上に塗膜層Ｌ１を形成した金属製品の被加飾材を対象にして、塗膜層Ｌ１にレーザー光を照射することで文字や絵柄などの加飾（マーキング）を行うことを前提にしている。ここでは、レーザー光の照射で、塗膜層Ｌ１を部分的に除去して、表面処理層Ｌ２とアルミニウム基材Ｌ３の一方又は両方の金属表面を見せることで、塗膜層Ｌ１と金属表面とのコントラストで加飾パターンを視認させる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the embodiment of the present invention targets a decorative material for a metal product in which a surface treatment layer L2 is formed on the surface of an aluminum base material L3 and a coating film layer L1 is further formed on the surface treatment layer L2. Therefore, it is premised that the coating film layer L1 is irradiated with a laser beam to decorate (marking) characters, patterns, and the like. Here, the coating film layer L1 is partially removed by irradiation with a laser beam to show the metal surface of one or both of the surface treatment layer L2 and the aluminum base material L3, thereby forming the coating film layer L1 and the metal surface. Make the decorative pattern visible with the contrast of.
この際、レーザー光照射による加飾を行った後、熱水殺菌処理などを施した場合には、加飾パターンの中に黒変部位が生じ、図１（ａ）に示すように、加飾パターン中の大きな範囲に黒変部位が生じた場合には、加飾パターンの視認性（コントラスト）が低下することになる。黒変の発生は、アルミニウム基材の素地に酸化膜が成長する際に、殺菌水などに含まれる金属イオン（Ｃａ，Ｍｇ，Ｓｉ等）が酸化膜に取り込まれて変色することによると考えられている。 At this time, if the decoration is performed by laser light irradiation and then subjected to hot water sterilization treatment or the like, a blackened portion is generated in the decoration pattern, and as shown in FIG. 1 (a), the decoration is performed. When a blackened portion occurs in a large area in the pattern, the visibility (contrast) of the decorative pattern is lowered. It is considered that the blackening occurs because the metal ions (Ca, Mg, Si, etc.) contained in the sterilizing water are taken into the oxide film and discolored when the oxide film grows on the base material of the aluminum base material. ing.
ここで、同様のレーザー光の強度でレーザー加飾を行って、その後に同様の処理を行った場合であっても、図１（ａ）に示すように、加飾パターンの中での黒変部位の範囲が大きい場合と、図１（ｂ）に示すように、加飾パターンの中での黒変部位の範囲が小さい場合があることを発見し、この原因を追求したところ、加飾パターンの中での表面処理層の残存面積を多くすることができれば、その後の黒変部位の範囲を小さくすることができることが分かった。 Here, even when laser decoration is performed with the same intensity of laser light and then the same processing is performed, blackening in the decoration pattern is performed as shown in FIG. 1 (a). We discovered that there are cases where the range of the blackened part is large and cases where the range of the blackened part in the decorative pattern is small, and when we pursued this cause, we found that the decorative pattern. It was found that if the remaining area of the surface-treated layer in the above can be increased, the range of the blackened portion after that can be reduced.
図１（ａ）に示すように、レーザー光照射時に加飾パターンの中で表面処理層の残存面積が少なくなっている場合には、その後の処理で、加飾パターン中の黒変部位の範囲が大きくなり、図１（ｂ）に示すように、レーザー光照射時に加飾パターンの中で表面処理層の残存面積が多い場合には、その後の処理で、加飾パターン中の黒変部位の範囲が小さくなる。 As shown in FIG. 1 (a), when the remaining area of the surface treatment layer in the decoration pattern is small during laser light irradiation, the range of the blackened portion in the decoration pattern in the subsequent treatment. As shown in FIG. 1 (b), when the remaining area of the surface treatment layer in the decoration pattern is large during laser light irradiation, the blackened portion in the decoration pattern is affected by the subsequent treatment. The range becomes smaller.
そして、図１（ａ）と図１（ｂ）の違いを積極的に生じさせることができれば、図１（ｂ）に示すように、加飾パターンの中の黒変部位を小さくして、加飾パターンの視認性を向上させることができると考え、鋭意研究した結果、図１（ａ）と図１（ｂ）の違いが、塗膜層Ｌ１の「色」と照射するレーザー光の「波長」との関係で生じることを見出した。 Then, if the difference between FIG. 1 (a) and FIG. 1 (b) can be positively generated, as shown in FIG. 1 (b), the blackened portion in the decorative pattern is reduced and added. As a result of diligent research, considering that the visibility of the decorative pattern can be improved, the difference between FIGS. 1 (a) and 1 (b) is the "color" of the coating film layer L1 and the "wavelength" of the laser light to irradiate. I found that it occurs in relation to.
図１（ａ）に示すように、レーザー光の照射によって形成される加飾パターン中にて、表面処理層Ｌ２の残存面積が少なくなる理由は、レーザー光が塗膜層Ｌ１を透過して表面処理層Ｌ２及びアルミニウム基材Ｌ３にダメージを与えるためであると考えられる。これに対して、図１（ｂ）に示すように、レーザー光の照射によって形成される加飾パターン中にて、表面処理層Ｌ２の残存面積が多くなる理由は、レーザー光の一部が塗膜層Ｌ１にて吸収されて、表面処理層Ｌ２及びアルミニウム基材Ｌ３にダメージを与え難くなったためであると考えられる。 As shown in FIG. 1 (a), the reason why the remaining area of the surface treatment layer L2 is small in the decorative pattern formed by the irradiation of the laser light is that the laser light passes through the coating film layer L1 to the surface. It is considered that this is because the treatment layer L2 and the aluminum base material L3 are damaged. On the other hand, as shown in FIG. 1 (b), the reason why the remaining area of the surface treatment layer L2 is large in the decorative pattern formed by the irradiation of the laser light is that a part of the laser light is applied. It is considered that this is because it is absorbed by the film layer L1 and it becomes difficult to damage the surface treatment layer L2 and the aluminum base material L3.
塗膜層Ｌ１におけるレーザー光の吸収度合いは、塗膜層Ｌ１の「色」によって異なる。図２は、塗膜層Ｌ１の色毎の分光反射率を示している。ここでの反射率が低い方が吸収率は高くなる。使用するレーザー光として、波長１０６４ｎｍのファイバーレーザーを用いる場合、「黒色」が最も吸収率が高く、その他の色（赤色、青色、緑色、黄色、クリア（透明））は吸収率が低い。 The degree of absorption of laser light in the coating film layer L1 differs depending on the "color" of the coating film layer L1. FIG. 2 shows the spectral reflectance of the coating film layer L1 for each color. The lower the reflectance here, the higher the absorption rate. When a fiber laser having a wavelength of 1064 nm is used as the laser light, "black" has the highest absorption rate, and other colors (red, blue, green, yellow, clear (transparent)) have the lowest absorption rate.
そこで、実際に、使用するレーザー光として、波長１０６４ｎｍのファイバーレーザーを用い、塗膜層Ｌ１の「色」を黒色にしてレーザー加飾を行ってみると、図１（ｂ）に示すように、その後に熱水殺菌処理を行った場合に、加飾パターン中の黒変部位の範囲が小さくなる。これに対して、塗膜層Ｌ１の「色」を赤色などにして同様のレーザー加飾を行い、その後に熱水殺菌処理を行うと、図１（ａ）に示すように、加飾パターン中の黒変部位の範囲は大きくなった。 Therefore, when a fiber laser having a wavelength of 1064 nm is actually used as the laser light to be used and the "color" of the coating film layer L1 is changed to black to perform laser decoration, as shown in FIG. 1 (b). When the hot water sterilization treatment is subsequently performed, the range of the blackened portion in the decorative pattern becomes smaller. On the other hand, when the "color" of the coating film layer L1 is changed to red or the like and the same laser decoration is performed, and then the hot water sterilization treatment is performed, as shown in FIG. 1A, the decoration pattern The range of the blackened part of was increased.
このような検討結果を纏めると、アルミニウム基材Ｌ３の表面に、表面処理層Ｌ２を介して塗膜層Ｌ１を形成し、塗膜層Ｌ１にレーザー光を照射して加飾を施すレーザー加飾方法においては、レーザー光の照射位置における塗膜層Ｌ１の色を、レーザー光の波長の吸収率が高い色に設定することで、その後に、加飾パターン中に大きな黒変部位が生じて、加飾パターンの視認性が低下することを抑止することができる。特に、レーザー光が波長１０６４ｎｍのファイバーレーザーのような近赤外域の場合には、塗膜層Ｌ１の「色」を「黒色」にすることで、加飾パターン中の黒変を効果的に抑止することができる。 Summarizing the results of such studies, laser decoration is performed by forming a coating layer L1 on the surface of the aluminum base material L3 via the surface treatment layer L2 and irradiating the coating layer L1 with laser light to decorate the coating layer L1. In the method, the color of the coating film layer L1 at the irradiation position of the laser light is set to a color having a high absorption rate of the wavelength of the laser light, and thereafter, a large blackening portion is generated in the decoration pattern. It is possible to prevent the visibility of the decorative pattern from being lowered. In particular, when the laser light is in the near infrared region such as a fiber laser having a wavelength of 1064 nm, blackening in the decorative pattern is effectively suppressed by changing the "color" of the coating film layer L1 to "black". can do.
図３は、紫外域から可視光域における塗膜層の色毎の分光反射率を示している。ここで注目すべきは、紫外光域での各色の吸収率（反射率）である。紫外域においては、クリア（透明）を除けば、殆どの色で吸収率が高くなる。このため、レーザー光として、ＵＶレーザー（例えば、波長３５５ｎｍ）を用いることで、塗膜層Ｌ１の「色」は、クリアを除く各色（黒色、赤色、青色、緑色、黄色など）で、加飾パターン中の黒変を効果的に抑止することができる。 FIG. 3 shows the spectral reflectance of each color of the coating film layer from the ultraviolet region to the visible light region. What should be noted here is the absorptance (reflectance) of each color in the ultraviolet light region. In the ultraviolet region, the absorption rate is high for most colors except clear (transparent). Therefore, by using a UV laser (for example, a wavelength of 355 nm) as the laser light, the "color" of the coating film layer L1 is decorated with each color (black, red, blue, green, yellow, etc.) except clear. Blackening in the pattern can be effectively suppressed.
上記の表１は、黒変抑止効果を示した実施例である。表面処理層Ｌ２を形成したアルミニウム基材Ｌ３に各色の塗膜層Ｌ１を形成し、ファイバーレーザー（波長：１０６４ｎｍ）とＵＶレーザー（波長：３５５ｎｍ）を用いてレーザ刻印を行った後、１２５℃で３０分間の熱水殺菌処理を行い、その後のレーザー刻印部の黒変状態を目視で確認した。ファイバーレーザーによるレーザー刻印では、黒色の塗膜層Ｌ１において、熱水殺菌処理後の黒変抑止効果が確認でき、ＵＶレーザーによるレーザー刻印では、黒色、赤色、青色、緑色、黄色の塗膜層Ｌ１において、熱水殺菌処理後の黒変抑止効果が確認できた。 Table 1 above is an example showing the effect of suppressing blackening. A coating layer L1 of each color is formed on the aluminum base material L3 on which the surface treatment layer L2 is formed, laser engraving is performed using a fiber laser (wavelength: 1064 nm) and a UV laser (wavelength: 355 nm), and then the temperature is 125 ° C. The hot water sterilization treatment was performed for 30 minutes, and then the blackening state of the laser engraved portion was visually confirmed. Laser engraving with a fiber laser confirms the blackening suppression effect after hot water sterilization in the black coating layer L1, and laser engraving with a UV laser confirms the black, red, blue, green, and yellow coating layers L1. In, the effect of suppressing blackening after the hot water sterilization treatment was confirmed.
以上説明したように、本発明の実施形態に係るレーザー加飾方法は、使用するレーザー光の波長と塗膜層Ｌ１の「色」との関係を適正に選択することで、視認性の高いレーザー加飾を行うことが可能になる。このレーザー加飾方法は、塗膜層が形成された缶容器の表面にレーザー加飾を行う場合に効果的であり、その後に、熱水殺菌処理を行った場合にも、加飾パターン中の黒変部位を小さく抑えることができ、視認性の高い加飾パターンを維持することができる。 As described above, in the laser decoration method according to the embodiment of the present invention, a laser having high visibility is obtained by appropriately selecting the relationship between the wavelength of the laser light to be used and the "color" of the coating film layer L1. It becomes possible to decorate. This laser decoration method is effective when the surface of the can container on which the coating film layer is formed is laser-decorated, and even when the hot water sterilization treatment is subsequently performed, the decoration pattern is included. The blackened part can be kept small, and a highly visible decorative pattern can be maintained.
