この発明は金属箔の電解製造方法に係り、詳しくは薄い
金属箔を製造するための技術に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for electrolytically manufacturing metal foil, and more particularly to a technique for manufacturing thin metal foil.

れている。(Prior art and problems to be solved by the invention) Conventionally, a cathode and an anode are immersed in an electrolytic solution and electricity is applied to deposit metal on the surface of the cathode. A metal foil is produced by peeling it off from the cathode. things are being done.

6 and an anode 108' opposite thereto, and while rotating the drum 104, these cathodes 106.
Electricity is passed between the anodes 108 to continuously deposit electrolytic metal on the drum surface, and the deposited metal film is peeled off from the drum surface to form a metal foil.

をより薄く製造することが要請されて来ている。This metal foil is, for example, a heat absorbing material, an electromagnetic shielding material,
It is used as a surface material for discs, but in recent years there has been a demand for such metal foil to be made thinner.

のである。However, in such an electrolytic manufacturing method, it has not been possible to manufacture a thin metal foil that satisfactorily satisfies this requirement. When the metal deposited on the cathode surface is peeled off from the cathode, if the film thickness is too thin, the metal film may not be peeled off at all from the cathode, or a portion may remain on the cathode surface and not be peeled off as a clean film. That's what I do.

Ｔｉ合金材を用いるようにしたことにある。(Means for Solving the Problems) As a result of intensive research and testing by the present inventors in order to obtain a thin metal foil that could not be obtained conventionally using such an electrolytic manufacturing method,
The present invention was completed based on the discovery that by using a specific material as the cathode material, even if the thickness of the metal electrodeposited on the surface of the cathode is extremely thin, it can be effectively peeled off from the cathode. The gist of this method is to deposit a metal film on the surface of the cathode by immersing a cathode and an anode in an electrolytic solution and applying electricity, and to separate the deposited metal film from the cathode surface. In manufacturing the foil, Ni − is used as the cathode material.
The reason is that a Ti alloy material is used.
即ち、従来の電解製造方法において陰極材料として一般
に用いられているＣｕ、ステンレス鋼。That is, Cu and stainless steel are commonly used as cathode materials in conventional electrolytic manufacturing methods.

のである０例えば上記従来の方法においては数ｌＯ蒔以
上の金属箔しか製造でさなかったのが、本発明によれば
１ＯＰＬ程度の厚さの金属箔でも製造できるようになる
。Instead of Ti, etc., we used an old-Ti alloy material, which made the release property of the metal deposited on the cathode surface extremely good, so even if the film thickness of the deposited metal was thin, The electrodeposited metal film can now be easily peeled off from the cathode, making it possible to manufacture extremely thin metal foils.For example, in the conventional method described above, only several liters of metal foil can be manufactured. However, according to the present invention, it becomes possible to manufacture metal foil with a thickness of about 1 OPL.

、 Ｎｏ。The reason why the peelability of the deposited metal improves when such a Ni-Ti alloy is used as a cathode material is thought to be related to the affinity of both metals at their interface, but the details are unknown. This invention was completed based on facts discovered in the process of conducting various experiments,
According to experiments, various compositions can be used as the old-Ti alloy, but when using one with a Ni content of 50 to 60i% and the balance being Ti, Further Fe, Co, Cu at 45 to 80% by weight
