example

[0102] The present invention will be described in more detail below based on examples. However, the example is only illustrative, and the drum electrode and the like of the present invention are not limited thereto. The scope of the present invention is determined by the appended claims, and encompasses all modifications equivalent to the meaning and scope of the claims.

example 1

[0104]

[0105] 24 discs made of aluminum with a thickness of 1 mm and a diameter of 200 mm were prepared, and a through hole with a diameter of 40 mm was formed in the center of each disc.

[0106] Twenty-five insulating discs made of vinyl chloride having a thickness of 4 mm and a diameter of 199 mm were prepared, and each disc was formed with a through-hole having a diameter of 40 mm in the center.

[0107] Insulating discs and discs made of aluminum alternate and are securely bolted. A power supply layer made of titanium having a diameter of 39 mm and a length of 250 mm was inserted into the through-hole portion located at the center, and was firmly fixed by a jig. Thus, a drum-shaped electrode 1 was obtained in which linear protruding electrodes having a width of 1 mm and continuously extending in the circumferential direction were formed at intervals of 4 mm.

[0108] The protruding electrodes of the drum electrode 1 thus obtained were subjected to an aluminum plating...

example 2

[0119]

[0120] A drum made of aluminum with a diameter of 200 mm was prepared, and 24 linear projections extending continuously in the circumferential direction were formed at intervals of 4 mm. The width of the protrusion was set to 1 mm, and the height of the protrusion was set to 1.5 mm.

[0121] The entire surface of the aluminum drum was coated with fluororesin (ETFE) with a thickness of 0.6 mm. Since the fluororesin layer was also formed on the surface of the protrusion, the surface coated with the fluororesin was scraped off until the surface of the protrusion was exposed. An aluminum plating layer with a thickness of 0.5 mm was grown on the surface of the protrusion (aluminum) exposed from the surface of the fluororesin. Thus, the drum-shaped electrode 2 in which the linear protruding electrodes 63 having a width of 1 mm and extending continuously in the circumferential direction were formed at intervals of 4 mm was obtained.

Abstract

A drum-shaped electrode for use in a device capable of electroplating metal on a surface having conductivity of a long substrate, the drum-shaped electrode comprising: a power supply layer; an insulating layer covering the surface of the power supply layer; and protruding electrodes , which protrude from the surface of the insulating layer and are electrically connected to the power supply layer, wherein the protruding electrodes are arranged linearly along the circumferential direction of the drum-shaped electrode.

Description

technical field [0001] The present invention relates to a drum-shaped electrode for electroplating the surface of a resin molded body having a three-dimensional network structure with metal in a plating tank. The present invention also relates to a method of producing a drum electrode, a plating apparatus each using the drum electrode, a method of producing a resin molded body, and a method of producing a porous metal body. Background technique [0002] In recent years, metal porous bodies having a three-dimensional network structure have been widely used in electrodes of batteries, various filters, catalyst supports, and the like. The metal is usually obtained by imparting electrical conductivity to the surface of a resin molded body having a three-dimensional network structure (for example, foamed urethane or foamed melamine), plating the surface of the resin molded body with metal, and then removing the resin molded body by means of heat treatment or the like porous body...
