Field of the Invention The present invention relates to a drum used as a cathode when a metal foil having a large number of small holes formed in a predetermined pattern (hereinafter referred to as a porous metal foil) is manufactured by an electrolytic deposition method ( Here, referred to as an electrodeposition drum or simply a drum).

For example, as a nickel-hydrogen battery electrode, a nickel-plated foil (a thin steel plate plated with nickel) with a thickness of about 60 μm having small holes with a diameter of about 1 to 3 mm is used. It is desired to make the thickness as thin as possible, and recently, an extremely thin foil of about 35 μm has been put to practical use.

するとドラム１の表面にニッケルが薄く電着するので、
それを剥ぎ取ってニッケル箔４として採取する。FIG. 1 is a schematic diagram for explaining the principle of the electrolytic deposition method. Hereinafter, production of nickel foil will be described as an example. In this method, a drum 1 to be a cathode and an anode 2 made of nickel are arranged at a predetermined interval, and an electrolytic solution 3 (a solution of nickel sulfate, nickel chloride or the like in the case of producing a nickel foil) is flown between the drum 1 and the drum. Energize while rotating. Then, since nickel is thinly electrodeposited on the surface of the drum 1,
It is stripped off and collected as nickel foil 4.

ル箔は多孔の箔となる。The drum 1 is made of a material such as titanium which is insoluble in the electrolytic solution, and is shown in FIG. 2 (partially developed view of the drum surface).
As shown in (1), the base material (titanium plate) 1-1 is provided with a large number of holes 1-2 corresponding to the holes of the metal foil to be the product. Then, the hole is filled with an insulating resin 5, as shown in FIG. By doing so, nickel is not electrodeposited on the holes 1-2 on the surface of the drum 1, and the obtained nickel foil becomes a porous foil.

不可能になる。According to the above method, in principle, a porous metal foil can be continuously produced, but there is a big problem to be solved before putting the technique into practical use. . One of them is that, when the deposited metal foil 4 is peeled off from the drum 3 as shown in FIG. 1, the resin 5 filled in the holes of the drum adheres to the metal foil and escapes. If so, electrodeposition also occurs in the holes (the inner surface thereof) where the metal should not be electrodeposited, making it impossible to manufacture the intended porous metal foil.
【０００７】もう一つの問題は、同じく金属箔の剥離の
際に、箔が破損しがちなことである。特に、極薄箔ある
いは空孔率の大きな箔では、ドラムからの剥離作業がう
まくいかずに箔が破れてしまうことが多い。Another problem is that the foil is apt to be damaged when the metal foil is peeled off. In particular, with an extremely thin foil or a foil having a large porosity, the peeling operation from the drum is often unsuccessful and the foil is often torn.

という難点がある。Regarding the escape of the above resin, one solution is disclosed in Japanese Patent Laid-Open No. 8-100288. The method is to cool the surface of the drum immediately after it comes out of the electrolytic solution by cooling with cold water to reduce the adhesion between the metal foil and the drum (resin), but its effect is doubtful.
Even if it is effective, there is a problem that the composition of the electrolytic solution and the temperature change due to the cooling water, and the conditions for electrolytic deposition fluctuate.

明に到った。The inventor has found that the problems of resin escape from the holes of the cathode drum and damage to the metal foil are due to the cathode drum used for electrolytic deposition. Therefore, the structure of the holes provided on the surface of the drum and the resin to be filled in the holes were studied in detail, and the present invention was completed.

うに、金属４は隙間にも入り込んで、あたかもくさびを
打ち込んだように析出する。As shown in FIG. 3A, the holes of the drum 1 are filled with an insulating resin 5. However, when the upper end portion is closely observed, there is a gap 6 between the inner surface of the hole and the resin, as shown in (b). When electrolytic deposition is performed using such a drum as a cathode, the metal 4 enters into the gap as shown in FIGS. 7C and 7D, and deposits as if a wedge had been driven.

る。When the metal foil deposited as described above is to be peeled off from the drum, the portion that has entered the gap acts like a lever and the resin 5 is pulled out from the hole, or the metal foil is peeled off. It becomes resistance and causes damage to the foil itself. Even if the resin can be peeled off without escaping and the foil is not damaged, the pores of the obtained foil are not uniform, which is not preferable as a porous metal foil product.

記の隙間６が生じるのである。The gap at the upper edge of the hole as described above is caused by the volume contraction of the resin filled in the hole. As the resin, a thermoplastic resin such as polyethylene or polypropylene is usually used, which is melted by heating, filled in the holes, and cooled and solidified. Volume shrinkage occurs in the process of solidification, and the gap 6 is generated.

Is a state where metal 4 is deposited on the drum surface, and (d) is an enlarged view of the C portion. At the upper edge of the hole of this drum, there is no gap 6 as shown in FIG. Therefore, the phenomenon that the deposited metal bites like a wedge does not occur.

い。樹脂表面のくぼみは、電析に何の障害にもならな
い。In order to obtain the shape of the upper edge of the hole as shown in FIG. 4, it is necessary that the resin does not separate from the inner surface of the hole when it solidifies and shrinks. In other words, it is sufficient that the adhesive force between the resin and the inner surface of the hole is larger than the peeling stress from the inner peripheral wall due to the contraction of the resin. In that case, even if the resin shrinks in volume when it solidifies, the surface only dents as shown in FIG. 4, and no gap is formed between it and the inner peripheral wall of the hole. The depressions on the resin surface do not hinder electrodeposition.

めて好適である。As the resin to be filled in the hole of the drum of the present invention, there are epoxy resin, silicone resin and the like. Among them, the silicone resin is preferable. Silicone resin is electrically insulating and has a large adhesive force with metal. Further, since the volume shrinkage upon curing is small, it is very suitable for use for the above purpose.

る。The silicon resin can be filled, for example, by pushing it into the hole using a roller or a spatula, or by housing the drum and the resin in a container and depressurizing the container to inject the resin into the hole. Can be done at. The silicone resin is soft and plastic at room temperature, and after filling as described above, it absorbs moisture in the air and hardens. You may heat to accelerate | stimulate hardening. Next, the shape (relationship between diameter and depth) of the holes provided on the surface of the drum of the present invention will be described.

る。その理由は下記のとおりである。FIG. 5 is a diagram showing some examples of the shapes of the holes. The hole may penetrate the drum body (titanium plate) 1-1 as shown in (a), or may have a bottom as shown in (b) and (c). However, in any case, the ratio (L / D) between the depth L and the diameter D is 1 or more. The reason is as follows.

る。As shown in FIG. 4, in the drum of the present invention, the phenomenon that the deposited metal bites between the resin and the inner wall of the hole does not substantially occur. However, since the metal deposition occurs in the three-dimensional direction, some of the metal is overlaid on the resin, and after some long-term deposition work, microscopically, the resin and pores are not visible. There may be a minute gap between the inner walls of the. In such a case, when peeling off the deposited metal foil, the resin may adhere to the foil and escape.

る必要はなく、上限は５程度にとどめてよい。In order to prevent the above resin from coming off,
The adhesive force between the resin and the inner surface of the hole may be made larger than the adhesive force between the resin and the metal foil. As a result of conducting a number of experiments based on such consideration, when the L / D is set to 1 or more, the adhesive force between the resin and the inner surface of the hole becomes sufficiently large, and the resin is almost completely prevented from coming out. It turns out that it can be prevented. It should be noted that the larger the L / D is, the more preferable it is for preventing slipping out, but since it takes time to process the holes, it is not necessary to increase it unnecessarily, and the upper limit may be limited to about 5.

る。In order to increase the adhesive force between the resin and the inner surface of the hole, it is effective to subject the drum surface to a surface treatment such as a chromate treatment, a silane coupling treatment, a titanate treatment or the like. Further, as shown in FIG. 6, the vertical cross-sectional shape of the hole may be a drum shape or an upper trapezoid. However, even if these methods are used together, the L / D should be 1 or more.

The drum 1 is a hollow cylinder made of pure titanium having a diameter of 400 mm, a width of 200 mm and a thickness of 10 mm. The hole is a straight bottomed hole,
The diameters were 1.0 mm, 1.5 mm and 2.0 mm, and the depth was changed as shown in Table 1. The holes were arranged in a staggered shape as shown in FIG. 2, and the holes were filled with the resin shown in Table 1.

記する。The rotating speed of the drum was 0.13 m / min, and the deposited nickel foil was continuously peeled off. The performance of the drum was evaluated based on the length at which the continuous peeling was possible (the length before the foil was broken) and the quality of the foil shape. The results are also shown in Table 1.

The foil had a regular shape of the holes and was very good as a product. When the drum was inspected, it was found that the resin packed in the hole did not fall out, and there was almost no gap between the resin and the inner surface of the hole.

This is because, in these drums, a considerably large gap is formed between the resin and the inner surface of the hole, and nickel electrodeposition occurs in the gap.

In Test No. 3 which is less than the above, the resin fell off and the continuous production of the foil having a good shape was less than 20 m. Example using polyethylene or polypropylene (No.3, 4)
In the case of L / D, even if L / D is 1 or more, the resin falls off. This is because the adhesive strength of the resin itself is weak.
