Antifouling property or easy wiping is required. As a resin having such characteristics, a polyolefin-based resin, particularly an ultra-high-molecular-weight polyethylene, may be applicable. However, since this resin has poor adhesiveness at the same time, it is difficult to coat the resin stably.

なされている。From the viewpoint of imparting insulating properties to a metal surface, a partial insulating coating of a metal plate for metal electrolytic refining is mentioned. For electrolytic refining, a refining method is widely used in which a plate-shaped cast coarse metal plate is used as an anode in an aqueous electrolytic solution and electricity is passed between the cathode and a pure metal is deposited and collected on the cathode plate. Is
BACKGROUND ART A metal plate having good electrodeposition properties and removability with respect to an electrodeposited metal, for example, an aluminum plate is used in copper refining.
In this case, after energization in the electrolytic solution for a certain period of time, the electrodeposited cathode plate is pulled up from the electrolytic cell, the electrodeposited metal is peeled off from the surface of the aluminum plate, and the electrodeposited metal is collected and the aluminum plate is removed. It has been repeatedly used for cathode plates.

剥離するのを容易にしていた。[0004] The electrodeposited metal deposited on the aluminum plate during electrolysis is deposited along the surface of the aluminum plate and around the periphery thereof, so that it is difficult to remove the electrodeposited metal after the electrolysis. With respect to the metal plate for electrolysis, the conventional technology is that an aluminum plate used for the cathode is coated with a band-shaped insulator over the periphery thereof to prevent electrodeposition on the periphery thereof, It was easy to separate the electrodeposited metal from the plate from its edge.

５号公報明細書）。[0005] As such an insulator, an ultra-high molecular weight polyethylene sheet is used as an insulating masking material because of its excellent insulating properties, chemical resistance and abrasion resistance. Attached to the periphery of the aluminum plate so as to wrap around from the front and back, a low molecular weight polyethylene-based sheet was interposed between this polyethylene sheet and the aluminum plate as an adhesive, and this was heated and melted to obtain an ultrahigh molecular weight An insulating coating method for bonding a polyethylene sheet is known (for example, Japanese Patent Publication No. 5-1579).

着力を発揮することができなかった。As described above, the peripheral portion of the aluminum plate for the cathode is masked. However, the portion of the aluminum plate surface where the electrolyte and the air come into contact, that is, the gas-liquid boundary is located at the liquid level of the electrolyte. It is likely to be corroded preferentially by the swing of the plate, and the plate thickness is easy to decrease, and since this part forms the upper end of the electrodeposited metal layer and adheres to the aluminum plate, it is difficult to peel off the electrodeposited metal after electrolysis. Yes, insulation masking is required. However, even if the gas-liquid boundary is covered by the above-mentioned conventional method using an ultra-high molecular weight polyethylene sheet, the adhesion to metal is not sufficient,
Since this portion has a large area in the plane portion, it was not possible to exert a sufficient adhesive force.
