【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、黒色度のＬ値および外観とも良好な黒色
制振鋼板の製造方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for producing a black vibration-damping steel sheet having a good L value of blackness and an excellent appearance.
最近、事務機器や家電製品等には、黒色鋼板が使用さ
れている。これは、機器メーカーで黒色塗料を省略した
り、高級化のイメージを付与したりするために、加工
前、予め電解処理等によって黒色化したものである。Recently, black steel plates have been used for office equipment and home appliances. In order to omit the black paint or give a high-grade image to a device manufacturer, this is blackened by electrolytic treatment or the like before processing.
ところが、近年になって、これら事務機器や家電製品
に、騒音を低減させる目的で、制振性を付与した黒色鋼
板を要求されるようになってきた。However, in recent years, black steel sheets having vibration damping properties have been required for these office equipment and home electric appliances for the purpose of reducing noise.
この要求に対応するべく方法としては、２枚の黒色鋼
板を用いて制振用樹脂を挟装し、上下鋼板を圧着させる
方法が考えられる。As a method to meet this demand, a method of sandwiching a vibration-damping resin using two black steel plates and press-bonding the upper and lower steel plates can be considered.

て外観を損なうという問題があった。However, in the manufacturing method as described above, two steel plates are blackened on one side at a stage before the resin layer is sandwiched, so that it is not necessary to make one black damping steel plate. It is necessary to perform blackening treatment once, and when these two blackened steel plates on one side are pasted together via the resin layer, they are usually thermocompression-bonded at about 180 ° C. Since it is in strong contact with the roll, the black coating may be peeled off and damaged, and the L value of the blackness may be lowered to impair the appearance.

A layer, a chromate layer formed on the blackening layer, and a black damping steel plate having a clear resin film on the outermost layer, and a resin between the steel plates for producing the damping steel plate. A method for forming a vibration-damping steel sheet by sandwiching layers, and then forming a blackening layer by electrolytic treatment, performing chromate treatment on the blackening layer, and further applying a clear resin on the blackening layer It is a thing.

For example, a method of forming a blackened layer on the vibration-damping steel plate by electrolytic treatment after forming a vibration-damping steel plate by interposing a resin between, for example, cold-rolled steel plates and subjecting this to Zn-Ni plating Therefore, the blackening process only needs to be performed once. Therefore, since the pressure roll is not passed under heating after the blackening treatment, the L value of the blackening layer does not decrease, and the peeling damage of the black film does not occur. Further, after the chromate treatment is applied onto the blackened layer, a clear resin is applied, so that the corrosion resistance is increased and the blackened layer is protected.

膜を保護する。In the figure, S 1 and S 2 are cold-rolled steel plates called skin steel plates, and 2 is a viscoelastic resin sandwiched between the steel plates S 1 and S 2 . Various types of resin are used depending on the purpose of use as a vibration damping steel plate. 3, 3 are a pair of pressure rolls, which are steel plates in which resin 2 is sandwiched.
S 1 and S 2 are pressed under heat and pressure-bonded to be integrated to form one damping steel plate 1 a (FIG. 1 (a)). Next, Zn-Ni plating is applied to the surface of the vibration-damping steel plate 1 to form a Zn-Ni plating layer 4 (FIG. 2 (b)). Ni in the plating bath at this time
6 to 20% is contained, and the coating weight is 3 to 40 g / m 2
Is appropriate. Next, the Zn-Ni-plated damping steel plate 1b is immersed in a solution containing ammonium sulfate and nitric acid, and reverse electrolysis is performed with the steel plate side as a positive electrode to form a blackened film on the surface of the damping steel plate 1b. 5 is formed ((c) in the same figure). However, the surface to be blackened at this time is the damping steel plate 1c depending on the application.
There may be only one side. Next, the surface of the vibration-damping steel plate 1c on which the blackening film 5 has been formed is subjected to chromate treatment to form a chromate conversion film 6 (FIG. 7 (d)), and this film 6
The clear resin 7 is applied on top ((c) of the same figure) to impart corrosion resistance to the blackened film 5 and protect the film.
