発明の具体的説明 本発明で用いる亜鉛とは、蒸留亜鉛他金１種（純度98.5
％以上）、最純亜鉛地金（純度99.995％以上）並びに電
気亜鉛地金（純度99.99％以上）が使用され、例えば、
上記蒸留亜鉛地金１種では、Pb1.5重量％以下、Cd0.1重
量％以下、そしてFe0.02重量％以下である。DETAILED DESCRIPTION OF THE INVENTION Zinc used in the present invention includes distilled zinc and one kind of gold (purity 98.5).
%), Pure zinc metal (purity 99.995% or more) and electric zinc metal (purity 99.99% or more) are used.
The above-mentioned one kind of distilled zinc metal has Pb of 1.5% by weight or less, Cd of 0.1% by weight or less, and Fe of 0.02% by weight or less.
Pb及び／またはCdを意図的に含めない場合には、こうし
た不純物の合計が1.5重量％以下の亜鉛地金を用いるこ
とが好ましい。If Pb and / or Cd are not intentionally included, it is preferred to use zinc ingots with a total of 1.5 wt% or less of these impurities.
不純物を極力排除したい場合には、Pb含有量が0.005重
量％以下の最純亜鉛地金及び電気亜鉛地金の使用が好ま
しい。When it is desired to remove impurities as much as possible, it is preferable to use pure zinc ingots having a Pb content of 0.005% by weight or less and electrolytic zinc ingots.
また、本発明で用いる着色用亜鉛合金とは、上記亜鉛に
発色元素であるTi、Mn、Ｖ等を添加したものである。The coloring zinc alloy used in the present invention is the above zinc to which coloring elements such as Ti, Mn and V are added.
着色用亜鉛合金は、該粉を溶融亜鉛上に散布する場合
は、上記亜鉛の融点以上、亜鉛の蒸発の少ない温度範囲
であることが望ましい。即ち、420℃前後であることが
望ましい。When the powder is dispersed on molten zinc, the zinc alloy for coloring is preferably in a temperature range equal to or higher than the melting point of zinc and less in evaporation of zinc. That is, it is desirable that the temperature is around 420 ° C.
例えば、発色元素をTiとするとすれば、0.1〜10wt％で
あるが望ましくは0.2〜5wt％である。融点が420℃前後
であるためである。For example, if the coloring element is Ti, the content is 0.1-10 wt%, but preferably 0.2-5 wt%. This is because the melting point is around 420 ° C.
溶融亜鉛への上記粉の溶け込みが良いためである。This is because the powder is well melted into the molten zinc.
また、前記粉を得るためには、例えば噴霧ノズルを用い
た方法により製造することが望ましい。粉砕は、し難い
ためである。In order to obtain the powder, it is desirable to manufacture the powder by a method using a spray nozzle, for example. This is because crushing is difficult.
また、他の付着法としては、溶射、PVD（蒸着、イオン
プレーティング、スパッタリング等）等である。Other deposition methods include thermal spraying, PVD (vapor deposition, ion plating, sputtering, etc.).
この場合であれば、発色元素の添加量が多いために融点
が上昇したとしても問題はない。In this case, there is no problem even if the melting point rises because the amount of coloring element added is large.
溶融亜鉛への溶け込みは容易なためである。This is because it is easy to melt into molten zinc.
上記の処理により、着色亜鉛材料の製造が容易となるも
のである。The above treatment facilitates the production of the colored zinc material.
上記の一連の処理は、着色用亜鉛合金が溶解するまで極
力非酸化性雰囲気とすることが望ましい。着色前に亜鉛
の酸化膜のみで表面が覆われ、発色が難しくなるためで
ある。It is desirable that the above series of treatments be performed in a non-oxidizing atmosphere as much as possible until the coloring zinc alloy is dissolved. This is because the surface is covered only with the zinc oxide film before coloring, which makes coloring difficult.
発色元素溶解後、酸化雰囲気、0.01〜21％O2である。望
ましくは、１〜５％酸素である。酸化が緩かに進み、発
色が鮮明となるためである。この際の温度は、溶融金属
の溶融点前後で、保持する。After the coloring element is dissolved, the oxidizing atmosphere is 0.01 to 21% O 2 . Desirably, it is 1 to 5% oxygen. This is because the oxidation proceeds slowly and the color becomes clear. The temperature at this time is maintained around the melting point of the molten metal.
Ti0.1〜0.6％wt％の着色用亜鉛合金を付着した場合で
は、450〜550℃前後に表面部が少なくとも保持される。
保持時間は、１秒〜15分間程度である。When a coloring zinc alloy with Ti of 0.1 to 0.6% wt% is attached, at least the surface portion is retained at around 450 to 550 ° C.
The holding time is about 1 second to 15 minutes.
さらに、鉄又は鉄鋼材料に溶融亜鉛メッキをした後に、
着色用亜鉛合金を前記溶融亜鉛メッキ物に付着した場合
も前記と同様に行われる。Furthermore, after hot-dip galvanizing iron or steel material,
The same applies to the case where the coloring zinc alloy is attached to the hot-dip galvanized product.
実施例１ 溶融亜鉛（蒸留亜鉛（98.5wt％Zn））を一定の容器内で
溶融し（500℃）板上の溶融亜鉛を形成し、その上にTi
0.6wt％を含む着色用亜鉛合金粉（50μ）を、前記溶融
亜鉛上に散布した。この際の雰囲気はAr雰囲気とし、溶
解完了後、空気を導入し酸化を行った。Example 1 Molten zinc (distilled zinc (98.5 wt% Zn)) was melted in a constant vessel (500 ° C.) to form molten zinc on a plate, and Ti was formed thereon.
Zinc alloy powder (50μ) for coloring containing 0.6 wt% was sprinkled on the molten zinc. At this time, the atmosphere was Ar atmosphere, and after the completion of melting, air was introduced to oxidize.
溶体は、500℃に保持し、酸化を進行させた。The solution was kept at 500 ° C. to promote oxidation.
酸化は、２分間行った。その後冷却し表面が青色の着色
亜鉛板が得られた。The oxidation was performed for 2 minutes. After that, it was cooled to obtain a colored zinc plate having a blue surface.
実施例２ 溶融亜鉛（蒸留亜鉛（98.5wt％Zn））を一定の条件で鉄
板にメッキし、その上にTi0.6wt％を含む着色用亜鉛合
金粉（50μ）を、散布した。Example 2 Molten zinc (distilled zinc (98.5 wt% Zn)) was plated on an iron plate under constant conditions, and a zinc alloy powder for coloring (50 μm) containing 0.6 wt% of Ti was sprinkled thereon.
この際の雰囲気はAr雰囲気とし、前記粉が溶解後、空気
を浸入させ酸化を行った。The atmosphere at this time was an Ar atmosphere, and after the powder was dissolved, air was introduced to oxidize the powder.
酸化は、３分間行った。表面が茶色の着色亜鉛メッキさ
れた鉄板が得られた。The oxidation was performed for 3 minutes. A colored galvanized iron plate with a brown surface was obtained.
発明の効果 （１）溶融亜鉛メッキ法により着色用亜鉛合金をメッキ
する方法に比べ、メッキ槽内での亜鉛の酸化によりメタ
ルロス量が減少できる。EFFECTS OF THE INVENTION (1) Compared with a method of plating a coloring zinc alloy by a hot dip galvanizing method, the amount of metal loss can be reduced by the oxidation of zinc in a plating tank.
