[産業上の利用分野]
本発明は、鉄鋼材料の表面処理に適用され、鉄鋼表面を
黒色化するリン酸塩皮膜処理液に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a phosphate film treatment liquid that is applied to surface treatment of steel materials and blackens the surface of steel.
[従来例]
従来、鉄鋼材料の表面を黒色化する方法としては、黒染
、リン酸マンガン系皮膜、リン酸亜鉛系皮膜剤及び、塗
装を行うことは公知の技術である。[Conventional Example] Conventionally, methods for blackening the surface of steel materials include black dyeing, manganese phosphate coating, zinc phosphate coating, and painting.
まず黒染はアルカリ性溶液で140〜150℃で20〜
50分浸漬処理して酸化鉄皮膜を作るものである。これ
は、外観は青黒色〜茶褐色〜黒色まで色々あり、表面が
滑らかで光沢があるけれども耐蝕性及び作業性が悪い。First, black dyeing is done with an alkaline solution at 140-150℃ for 20~
An iron oxide film is created by immersion treatment for 50 minutes. The appearance varies from blue-black to brownish-brown to black, and although the surface is smooth and glossy, corrosion resistance and workability are poor.
リン酸マンガン系皮膜は95〜沸騰状態で20〜30分
処理してリン酸マンガン皮膜を作る。これは外観は灰黒
色〜黒色であり、耐摩耗性及び耐蝕性は良いが、皮膜が
粗く作業性も悪い。リン酸亜鉛系皮膜は90〜沸騰状態
で20〜30分間処理づることによりリン酸亜鉛鉄皮膜
を作る。これは外観は灰黒色〜黒色であり、耐蝕性は良
いが、皮膜が粗い。又処理液中には酸化剤としてNox
を含んでいる。塗装は外観は良好であるが、密着性や作
業性に問題がある。A manganese phosphate film is formed by processing at a boiling temperature of 95°C for 20 to 30 minutes. This has a grayish-black to black appearance and has good wear resistance and corrosion resistance, but the coating is rough and has poor workability. Zinc phosphate-based coatings are treated at 90 to boiling temperature for 20 to 30 minutes to form zinc iron phosphate coatings. This has a grayish-black to black appearance and has good corrosion resistance, but the film is rough. In addition, the processing liquid contains Nox as an oxidizing agent.
Contains. Although the paint looks good, there are problems with adhesion and workability.
特に塗装及び乾燥等の作業性並びに各種性能を十分満足
することができないのが現、状である。In particular, the current situation is that workability such as painting and drying, as well as various performances, cannot be fully satisfied.
[発明の目的]
本発明は従来例における欠点を除去し、作業性が良好で
あると共に、皮膜の外観は黒色緻密で耐蝕性に優れたリ
ン酸塩皮膜を鉄鋼材料表面に形成させることができるリ
ン酸塩処理液を提供することを目的とするものである。[Object of the invention] The present invention eliminates the drawbacks of the conventional method, and can form a phosphate film on the surface of a steel material that has good workability, has a dense black appearance, and has excellent corrosion resistance. The purpose is to provide a phosphate treatment solution.
[発明の構成]
上記目的を達成させるためになされた本発明は、硝酸イ
オン及び亜硝酸イオンを含まないリン酸亜鉛処理液に、
ニッケルイオン0.05〜!M#。[Structure of the Invention] The present invention, which has been made to achieve the above object, includes a zinc phosphate treatment solution that does not contain nitrate ions and nitrite ions.
Nickel ion 0.05 ~! M#.
塩素酸イオン0.5〜8g/l及び鉄イオン0.02〜
4g/9を含むと共に、前記リン酸亜鉛処理液中の亜鉛
イオン/リン酸イオンの重量比が0.07〜0.25で
あり、更に少量のキレート剤を添加した鉄鋼材料の黒色
化リン酸塩皮膜処理液である。Chlorate ion 0.5~8g/l and iron ion 0.02~
4g/9, the weight ratio of zinc ions/phosphate ions in the zinc phosphate treatment solution is 0.07 to 0.25, and a small amount of chelating agent is added. This is a salt film treatment liquid.
本発明の処理液においては、リン酸亜鉛処理液にニッケ
ルイオン、塩素酸イオン及び鉄イオンを共存させたもの
であって、被処理物から溶出してくる鉄分をすばやく3
価鉄イオンにして沈澱させ反応系外の成分にしてしまう
硝酸イオン及び亜硝酸イオンを実質的に含有させない点
に特徴が存するのである。そして、リン酸亜鉛処理液中
の亜鉛イオン/リン酸イオンの重量比を限定することに
よって黒色化を一段と助長させ黒色化の優れた皮膜が得
られるのである。In the treatment solution of the present invention, nickel ions, chlorate ions, and iron ions are made to coexist in the zinc phosphate treatment solution, and the iron content eluted from the object to be treated can be quickly removed.
It is characterized in that it does not substantially contain nitrate ions and nitrite ions, which are converted into valent iron ions and precipitated and become components outside the reaction system. By limiting the weight ratio of zinc ions/phosphate ions in the zinc phosphate treatment solution, blackening is further promoted and a film with excellent blackening can be obtained.
次に各イオン濃度の限定理由を述べる。Next, the reason for limiting each ion concentration will be described.
ニッケルイオンが、0.059/I以下になるとリン酸
塩皮膜の黒色化が不充分となり、57/」以上になると
経済的に不利である。If the nickel ion content is less than 0.059/I, the blackening of the phosphate film will be insufficient, and if it is more than 57/I, it will be economically disadvantageous.
塩素酸イオンが、0.5g/fJ以下になるとリン酸塩
皮膜の化成性および黒色化が不充分であり、81勺以上
になると酸化力が強すぎて処理液中に鉄イオンを維持さ
せるのが困難になる。If the chlorate ion is less than 0.5 g/fJ, the chemical formation and blackening of the phosphate film will be insufficient, and if it is more than 81 g/fJ, the oxidizing power will be too strong and it will be difficult to maintain iron ions in the processing solution. becomes difficult.
鉄イオンが、0.02g/41以下になると、リン酸塩
皮膜の黒色化が不充分となり、4g/、l1以上になる
とリン酸塩皮膜結晶が粗くなり耐蝕性が劣化する。If the iron ion content is less than 0.02 g/41, the blackening of the phosphate film will be insufficient, and if it is more than 4 g/11, the phosphate film crystals will become coarse and the corrosion resistance will deteriorate.
リン酸亜鉛処理液中の亜鉛イオン/リン酸イオンの重量
比が、0.07以下にな、ると化成されるリン酸塩皮膜
中の鉄分が多くなり耐蝕性が悪くなり、反対に0.25
以上になるとリン酸塩皮膜の黒色化が不充分となる。If the weight ratio of zinc ions/phosphate ions in the zinc phosphate treatment solution is less than 0.07, the iron content in the phosphate film that is chemically formed will increase, resulting in poor corrosion resistance; 25
If it is more than that, the blackening of the phosphate film will be insufficient.
本発明の黒色化リン酸塩皮膜処理液の好ましい成分範囲
は、亜鉛イオン2〜5グ/ρ、リン酸イオン20〜30
g/lニッケルイオン0.5〜2、(1/41、塩素酸

(1/fJである。The preferable component range of the blackening phosphate film treatment solution of the present invention is 2 to 5 g/ρ of zinc ion, 20 to 30 g/ρ of phosphate ion,
g/l nickel ions 0.5-2, (1/41, chlorate ions 1.5-5 g/l, 0 and iron ions 0.05-2.

被処理物が焼入材等で表面硬度か高いものについては、
処理液にエツチング剤を添加すると良い。If the object to be treated has a high surface hardness such as quenched material,
It is recommended to add an etching agent to the processing solution.
