Description

本発明は、アルミニウム陽極酸化染色処理品の耐光性向上用組成物に関する。   The present invention relates to a composition for improving light resistance of an anodized aluminum dyed product.

従来、アルミニウム又はその合金に耐食性を付与するために、硫酸水溶液などの電解液中でアルミニウム又はその合金を陽極として通電し、アルミニウム表面に多孔質の酸化アルミニウム皮膜を形成することが行われる(以下、陽極酸化処理という)。   Conventionally, in order to impart corrosion resistance to aluminum or an alloy thereof, it has been performed that an aluminum or an alloy thereof is energized in an electrolytic solution such as an aqueous sulfuric acid solution to form a porous aluminum oxide film on the aluminum surface (hereinafter referred to as “aluminum” or an alloy thereof). Is called anodizing).

更に、意匠性向上のため、アゾ染料、金属錯塩型アゾ染料、アントラキノン染料、フタロシアニン染料、キサンテン染料などの水溶性有機染料を含む染料水溶液に陽極酸化処理を施したアルミニウム又はその合金を浸漬し、プラスの電荷を持つ直径数十nmの通電孔内部にマイナスの電荷を持つ染料分子を静電気的に吸着させることで、アルミニウム又はその合金に着色する処理が行われている(以下、染色処理という)。これは、陽極酸化処理によって得られた酸化アルミニウム皮膜の多孔性を利用したものである。   Furthermore, in order to improve the design, anodic aluminum or its alloy is immersed in an aqueous dye solution containing a water-soluble organic dye such as an azo dye, a metal complex salt type azo dye, an anthraquinone dye, a phthalocyanine dye, or a xanthene dye, A process of coloring aluminum or an alloy thereof by electrostatically adsorbing a dye molecule having a negative charge inside a current-carrying hole having a positive charge of several tens of nm in diameter (hereinafter referred to as a dyeing process). . This utilizes the porosity of the aluminum oxide film obtained by anodizing treatment.

また、染色処理の後、多孔質の酸化アルミニウム皮膜の微細孔を閉じる処理である沸騰水法や酢酸ニッケル法などの封孔処理が一般的に行われている。   Further, after the dyeing process, a sealing process such as a boiling water process or a nickel acetate process, which is a process of closing the micropores of the porous aluminum oxide film, is generally performed.

アルミニウム又はその合金は、軽量で強度が強く、酸化アルミニウム皮膜は耐食性に優れるため、建材・車両などに利用され、また、以上のように染色処理によってさまざまな色調に仕上げることができることから、携帯電話やデジタルカメラなどモバイル機器にも利用されている。   Aluminum or its alloys are lightweight and strong, and the aluminum oxide film has excellent corrosion resistance, so it is used in building materials and vehicles, and can be finished in various colors by dyeing treatment as described above. It is also used for mobile devices such as digital cameras.

しかしながら、以上の陽極酸化処理及び染色処理(陽極酸化染色処理ということがある)によって、アルミニウム又はその合金を多彩な色調に仕上げることができる反面、従来の染色処理では有機染料を使用しているため、光に当たると退色し、耐光性が悪いという問題点がある。このため、アルミニウム又はその合金に陽極酸化処理及び染色処理を施して得られる処理品(アルミニウム陽極酸化染色処理品ということがある)の耐光性向上用組成物が求められ、種々検討されている。   However, the above anodizing treatment and dyeing treatment (sometimes referred to as anodizing dyeing treatment) can finish aluminum or its alloys in various colors, but conventional dyeing treatment uses organic dyes. When exposed to light, there is a problem of fading and poor light resistance. For this reason, a composition for improving light resistance of a treated product (sometimes referred to as an aluminum anodized dyed product) obtained by subjecting aluminum or an alloy thereof to anodizing treatment and dyeing treatment has been demanded and variously studied.

例えば、特許文献1には、染色処理を行った後、耐候性付与剤を含有するクリヤー系塗料を塗布し染色表面をコーティングすることを特徴とする染色アルマイト塗装物が開示されている。また、特許文献2には、耐候性向上用組成物として、水、乳化剤、光安定剤及び/又は紫外線吸収剤を含有する成分平均粒子径が150nm以下であることを特徴とする光安定剤乳化組成物が開示されている。   For example, Patent Document 1 discloses a dyed alumite coated product characterized by coating a dyed surface by applying a clear paint containing a weather resistance imparting agent after dyeing treatment. Patent Document 2 discloses a light stabilizer emulsification characterized in that a component average particle diameter containing water, an emulsifier, a light stabilizer and / or an ultraviolet absorber is 150 nm or less as a weather resistance improving composition. A composition is disclosed.

しかしながら、特許文献1の方法は、クリヤー系塗料を塗布するため、コーティング膜を形成する必要がある。また、特許文献2の方法は、粒子径の大きい乳化組成物を使用するため、直径数十nmの陽極酸化皮膜の通電孔内部に光安定剤を定着することができない。
特開2003−55794号公報 特開2006−249410号公報
However, since the method of Patent Document 1 applies a clear paint, it is necessary to form a coating film. Moreover, since the method of patent document 2 uses an emulsified composition with a large particle diameter, a light stabilizer cannot be fixed inside the current-carrying hole of an anodic oxide film having a diameter of several tens of nm.

本発明のアルミニウム陽極酸化染色処理品の耐光性向上用組成物の処理対象は、アルミニウム又はその合金を陽極酸化し、さらに染色処理を施したものである。   The object of treatment of the composition for improving light resistance of an aluminum anodized dyed product of the present invention is obtained by anodizing aluminum or an alloy thereof and further performing a dyeing treatment.

陽極酸化処理
アルミニウム又はその合金の陽極酸化処理は、従来公知の方法を適用すればよく、陽極酸化処理液中に被処理物であるアルミニウム又はその合金を浸漬して陽極酸化を行う。
A conventionally known method may be applied to the anodizing treatment of the anodized aluminum or its alloy, and the anodized aluminum or its alloy is immersed in the anodizing solution and anodized.

陽極酸化処理に使用する電解液としては、特に限定されず、例えば、硫酸水溶液系、シュウ酸水溶液系、クロム酸水溶液系、スルホン酸水溶液系等の電解液を使用すればよい。
処理液の液温は、例えば、0〜80℃程度、好ましくは10〜40℃程度である。
The electrolytic solution used for the anodizing treatment is not particularly limited. For example, an electrolytic solution such as a sulfuric acid aqueous solution system, an oxalic acid aqueous solution system, a chromic acid aqueous solution system, or a sulfonic acid aqueous solution system may be used.
The liquid temperature of a process liquid is about 0-80 degreeC, for example, Preferably it is about 10-40 degreeC.

電解方法は交流電解及び直流電解のいずれでも良いが、皮膜成長が早く、厚膜を容易に得ることができる点で直流電解が好ましい。   The electrolysis method may be either AC electrolysis or DC electrolysis, but DC electrolysis is preferred in that the film growth is fast and a thick film can be easily obtained.

電流密度は、例えば、0.1〜10A/dm程度、好ましくは0.5〜3A/dm程度である。
通電時間は、通常、10分〜100分間程度とすればよい。
The current density is, for example, about 0.1 to 10 A / dm 2 , preferably about 0.5 to 3 A / dm 2 .
The energization time may normally be about 10 minutes to 100 minutes.

陽極酸化によって形成される皮膜の厚みは、例えば、2〜50μm程度、好ましくは5〜20μm程度であり、用途に応じて任意に設定すればよい。   The thickness of the film formed by anodization is, for example, about 2 to 50 μm, preferably about 5 to 20 μm, and may be arbitrarily set depending on the application.

なお、陽極酸化処理を行う前に、まず、処理対象のアルミニウム又はその合金に対して、必要に応じて、付着物などを除去するための前処理を行う。前処理方法については、特に限定的ではなく、素材の種類、付着物の状態などに応じて、溶剤洗浄、酸洗浄、弱アルカリ洗浄、酸エッチング、アルカリエッチング、デスマット、化学研磨等の公知の処理方法を適宜適用すればよい。   In addition, before performing an anodizing process, first, the pre-process for removing a deposit etc. is performed with respect to the aluminum or its alloy to be processed as needed. The pretreatment method is not particularly limited, and known treatments such as solvent cleaning, acid cleaning, weak alkali cleaning, acid etching, alkali etching, desmutting, chemical polishing, etc., depending on the type of material and the state of deposits, etc. The method may be applied as appropriate.

上記アルミニウム又はその合金の陽極酸化処理を施した後、処理表面に染色処理を施す。   After the anodizing treatment of the aluminum or its alloy, the treated surface is dyed.

染色処理
染色処理は、従来公知の方法を適用すればよく、陽極酸化皮膜形成後のアルミニウム又はその合金に、染色法を使用して着色を施す。陽極酸化皮膜には、表面に直径数十nmの微細孔が形成されているため、染料が微細孔内に吸着され、染色が可能となる。
Dyeing treatment For the dyeing treatment, a conventionally known method may be applied, and the aluminum or its alloy after the formation of the anodized film is colored using a dyeing method. Since the anodic oxide film has micropores with a diameter of several tens of nm on the surface, the dye is adsorbed in the micropores and can be dyed.

染色処理の方法としては、例えば、染色液に処理物を浸せきして染色する浸せき染色(dip dyeing)、染色液を処理物に吹き付けて染色する吹付け染色(spray dyeing)、はけ、布等を使用して染色液を処理物に塗りつけて染色する塗布染色(daub dyeing)、スクリーン印刷、オフセット印刷などによって染料を含有したインキで直接印刷する印刷染色法(direct printing)等が挙げられる。   Examples of the dyeing method include immersion dyeing (dip dyeing) in which a treated product is immersed in a dyeing solution, dyeing by spraying the dyeing solution onto the treated material (spray dyeing), brushing, cloth, etc. And dyeing by applying a dyeing solution to a treated product using a dye (daub dyeing), screen printing, offset printing, direct printing with a dye-containing ink (direct printing), and the like.

使用する染料は特に限定されず、例えば、クロム酸塩アゾ染料(赤色)、アゾ染料(赤色)、キサンテン染料(ピンク色)、クロム錯塩アゾ染料(紫色)、銅フタロシアニン染料(青色)、アントラキノン染料(青色)、アゾ染料(黄色)、クロム錯塩アゾ染料(黄色)、クロム錯塩アゾ染料(黒色)等、従来公知の染料を使用すればよい。これらの染料は、1種単独で使用しても良いし、2種以上混合して使用しても良い。   The dye used is not particularly limited. For example, chromate azo dye (red), azo dye (red), xanthene dye (pink), chromium complex azo dye (purple), copper phthalocyanine dye (blue), anthraquinone dye Conventionally known dyes such as (blue), azo dye (yellow), chromium complex salt azo dye (yellow), chromium complex salt azo dye (black) may be used. These dyes may be used alone or in combination of two or more.

耐光性向上処理
耐光性向上処理は、前記の陽極酸化処理及び染色処理によって得られたアルミニウム陽極酸化染色処理品を、本発明の耐光性向上用組成物に接触させるものである。アルミニウム陽極酸化染色処理品を本発明の耐光性向上用組成物と接触させることにより、アルミニウム陽極酸化染色処理品の表面に効率よく耐光性を付与できる。
Light Resistance Improvement Treatment The light resistance improvement treatment is to bring the aluminum anodized dyed product obtained by the anodizing treatment and dyeing treatment into contact with the composition for improving light resistance of the present invention.

本発明で使用するヒンダードアミン系光安定剤は、1種単独で使用しても良いし、2種以上を混合して使用しても良い。   The hindered amine light stabilizer used in the present invention may be used alone or in combination of two or more.

通常、ヒンダードアミン系光安定剤は水に溶けにくく、水と混合して使用する場合には、特許文献2に記載のように、乳化剤を添加して水にヒンダードアミン系光安定剤を乳化させる。水中で乳化したヒンダードアミン系光安定剤は、そのサイズが大きいために直径数十nmの陽極酸化皮膜の通電孔内部に定着できない。   Usually, a hindered amine light stabilizer is hardly soluble in water, and when used by mixing with water, as described in Patent Document 2, an emulsifier is added to emulsify the hindered amine light stabilizer in water. The hindered amine light stabilizer emulsified in water cannot be fixed inside the current-carrying hole of the anodic oxide film having a diameter of several tens of nm because of its large size.

本発明においては、例えば、以下の(1)〜(3)に示すように、ヒンダードアミン系光安定剤を含有するpH3以下の水溶液を調製してヒンダードアミン系光安定剤を水に溶解することにより、ヒンダードアミン系光安定剤が水に溶解した澄明な水溶液が得られる。   In the present invention, for example, as shown in the following (1) to (3), by preparing an aqueous solution having a pH of 3 or less containing a hindered amine light stabilizer and dissolving the hindered amine light stabilizer in water, A clear aqueous solution in which the hindered amine light stabilizer is dissolved in water is obtained.

(1)まず、水にヒンダードアミン系光安定剤を加えて、水とヒンダードアミン系光安定剤を混合させる。この時点では、ヒンダードアミン系光安定剤は水に溶解せずに分離している。   (1) First, a hindered amine light stabilizer is added to water, and water and a hindered amine light stabilizer are mixed. At this point, the hindered amine light stabilizer is separated without dissolving in water.

(2)次に、酸を添加し、pHを3以下に調整する。この時点で、ヒンダードアミン系光安定剤は水に溶解し、澄明な水溶液となる。   (2) Next, an acid is added to adjust the pH to 3 or less. At this point, the hindered amine light stabilizer dissolves in water and becomes a clear aqueous solution.

上記(1)及び(2)の代わりに、水に酸を加えてpH3以下に調整した水溶液に、ヒンダードアミン系光安定剤を加える方法によっても、同様にヒンダードアミン系光安定剤が水に溶解した澄明な水溶液が得られる。   Instead of the above (1) and (2), the method of adding a hindered amine light stabilizer to an aqueous solution adjusted to pH 3 or less by adding an acid to water, similarly, the hindered amine light stabilizer is dissolved in water.

It is.

(3)上記(1)及び(2)のような方法によって得られる水溶液は、pH3以下なので、pH3を超える耐光性向上用組成物を得るためには、アンモニア、水酸化ナトリウム、水酸化カリウム、炭酸ナトリウム等のアルカリ成分を添加してpHを調整すればよい。pHを3以下に調整することにより澄明な水溶液になった耐光性向上用組成物にアルカリ成分を加えてpHを1〜9程度にしても、耐光性向上用組成物は澄明な水溶液のままである。   (3) Since the aqueous solution obtained by the methods (1) and (2) above has a pH of 3 or less, in order to obtain a composition for improving light resistance exceeding pH 3, ammonia, sodium hydroxide, potassium hydroxide, What is necessary is just to adjust pH by adding alkali components, such as sodium carbonate. Even if the pH is adjusted to about 1 to 9 by adding an alkali component to the composition for improving light resistance that has become a clear aqueous solution by adjusting the pH to 3 or less, the composition for improving light resistance remains a clear aqueous solution. is there.

本発明の耐光性向上用組成物中のヒンダードアミン系光安定剤は水に溶解しているので、ヒンダードアミン系光安定剤が直径数十nmの陽極酸化皮膜の通電孔内部に定着し、アルミニウム陽極酸化染色処理品の表面に効率よく耐光性を付与することができる。   Since the hindered amine light stabilizer in the composition for improving light resistance of the present invention is dissolved in water, the hindered amine light stabilizer is fixed inside the current-carrying hole of the anodic oxide film having a diameter of several tens of nm, and anodized aluminum. Light resistance can be efficiently imparted to the surface of the dyed product.

酸の添加量は、耐光性向上用組成物のpHが上記範囲になるように適宜調節すればよい。   What is necessary is just to adjust the addition amount of an acid suitably so that pH of the composition for light resistance improvement may become the said range.

酸としては、硫酸、硝酸、リン酸、塩酸、炭酸等の無機酸、リンゴ酸、クエン酸、シュウ酸、コハク酸、酢酸等の有機酸を使用すれば良く、これらの中でも硫酸、硝酸、リンゴ酸及びクエン酸が好ましい。これらの酸は、1種単独で使用しても良いし、2種以上を混合して使用しても良い。   As the acid, inorganic acids such as sulfuric acid, nitric acid, phosphoric acid, hydrochloric acid and carbonic acid, and organic acids such as malic acid, citric acid, oxalic acid, succinic acid and acetic acid may be used. Among these, sulfuric acid, nitric acid and apple Acid and citric acid are preferred. These acids may be used alone or in combination of two or more.

実施例1〜13で使用した耐光性向上用組成物は、下記の工程により作製した。   The composition for improving light resistance used in Examples 1 to 13 was prepared by the following steps.

耐光性向上用組成物の作製
ガラスビーカーに純水800mlを入れ撹拌し、ヒンダードアミン系光安定剤を0.1〜20g添加した。ヒンダードアミン系光安定剤は水に不溶であるため、この時点では、溶解せず、ヒンダードアミン系光安定剤と水は完全に分離していた。この液に、98%硫酸を10g添加して、pHを3以下にすることによって、ヒンダードアミン系光安定剤が水に完全に溶解し、ヒンダードアミン系光安定剤を含有する澄明な水溶液が得られた。得られた水溶液にアンモニア水を添加してpHを3〜7に調整し、さらに純水を添加して1Lの液量に調整し、実施例1〜13の耐光性向上用組成物を得た。

判定基準は、耐光性処理を施していない陽極酸化染色処理品の判定を各染料それぞれ△とし、各染料において耐光性処理を施していない陽極酸化染色処理品より色差が小さい場合を○、色差が大きい場合を×とした。   Judgment criteria are as follows: each dye has a △ anodic oxidation dyed product that has not been subjected to light resistance treatment, and the color difference is less than the anodic oxidation dyed product that has not been subjected to light resistance treatment in each dye. When it was large, it was set as x.

以上の試験結果を下記表3、4に示す。例えば、赤色の染料(TAC RED-GD(レッド・101))を使用した実施例1〜9と比較例1とを比較すると、耐光性試験前後の処理品の色差は、実施例1〜9の方が小さかった。同様に、例えば、青色の染料(TAC BLUE-SLH(ブルー・503))を使用した実施例11と比較例3とを比較すると、耐光性試験前後の処理品の色差は、実施例11の方が小さかった。   The above test results are shown in Tables 3 and 4 below. For example, when Examples 1 to 9 using a red dye (TAC RED-GD (Red 101)) are compared with Comparative Example 1, the color difference between the processed products before and after the light resistance test is that of Examples 1 to 9. It was smaller. Similarly, for example, when Example 11 using a blue dye (TAC BLUE-SLH (Blue 503)) is compared with Comparative Example 3, the color difference of the processed product before and after the light resistance test is that of Example 11 Was small.
