Example Embodiment

[0046] The accompanying drawing is a specific embodiment of the present invention.

[0047] The metal foil preparation method of the present invention is composed of the following steps in sequence:

[0048] a. Electrodeposition: take the industrial pure metal as the anode and the aqueous solution of the metal sulfamate or sulfate as the plating solution, so that the metal ions are deposited on the continuously rotating cathode roller, and the continuous growth and continuous peeling; electrodeposition in the plating tank By adjusting the current size and the rotation speed of the cathode roller, metal coatings of different thicknesses can be prepared, and by changing the plating solution formula and anode material, metal foils of different materials can be prepared;

[0049] b. Peeling: Using the tension generated by the rotation of the cathode roll and the winding system, the metal coating deposited on the cathode roll is continuously peeled off. Due to the rotation of the c...

Abstract

The invention discloses a manufacturing method of a metal foil, comprising the steps of electrolytic deposition, stripping, cleaning and rolling. The invention further relates to a metal foil and a manufacturing device thereof. The device comprises a coating bath, a cleaning groove and a rolling system which are sequentially arranged on a stand from a front part to a back part, a towing strippingdevice is arranged at the front upper part and the back upper part of the cleaning groove, a profiling titanium basket and a rotary cathode roller are arranged in the coating bath, and the profiling titanium basket is in a semi-arc shape and is arranged under the cathode electrode roller. The invention has advantages that a nano nickel (copper) foil with the thickness of 5-50 microns can be successfully obtained by the method and the device; the metal foil is bright and smooth, and has small stress, uniform thickness, compact crystal lattice, excellent toughness and corrosion resistance. The manufacturing method is simple, and the manufacturing device has small amount, small volume and low energy consumption.

Description

(1) Technical field [0001] The present invention relates to a metal foil and its preparation method and preparation equipment. (2) Background technology [0002] In the past, the manufacture of nickel (copper) foil was mostly a rolling process. From ingot rolling to thick plate and thin plate, many processes are required to roll nickel (copper) foil, which requires a large number of equipment, huge volume, and high energy consumption. After the final cold rolling process, recrystallization is required. Annealed. For example: an integrated multi-roll mill, its roll system has 8, 16, 32 rolls to be replaced repeatedly. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a metal foil, a preparation method and preparation equipment thereof, and the metal foil has good quality, simple preparation method, small number of preparation equipment, small volume and low energy consumption. [0004] The pre...
