Embodiment 1
[0052] see Figure 1-4 As shown, the present invention achieves the above object through the following technical scheme, a preparation device of 4.5um ultra-thin electrolytic copper foil, comprising an anode tank base platform 1, the top of the anode tank base platform 1 is connected with a support seat 2, and supports A cathode roller 3 is rotatably connected to the seat 2, and an anode tank mechanism 4 is arranged between the cathode roller 3 and the supporting seat 2.
[0053] The top of the support base 2 is provided with a second-layer table top 5, and the second-layer table top 5 is respectively provided with a brushing mechanism 6, a peeling and trimming mechanism 7, an anti-oxidation mechanism 8, a drying fan cooling mechanism 9, a water washing mechanism 10 and a winding mechanism 11.
[0054] The top of the second-floor platform 5 is connected with a first support frame 601 , on which a support block 603 is slidably connected by a reciprocating drive motor 602 , and...
Embodiment 2
[0063] A preparation process of 4.5um ultra-thin electrolytic copper foil, which adopts the preparation device of embodiment 1, comprising the following steps:
[0064] S1, cutting the electrolytic copper into strips or blocks before loading into the copper melting tank;
[0065] S2, put the copper material into a copper-dissolving tank with high solvency, add sulfuric acid and pure water to prepare a sulfuric acid solution, and then blow air into the copper-dissolving tank;
[0066] S3, performing multi-stage filtration to the copper sulfate solution configured in step S2;
[0067] S4, the prepared copper sulfate solution is pumped from the supply liquid to a fully-sealed high-level tank and cooled by a heat exchanger for standby. The copper sulfate solution is transported by a pipeline, and the flow of the electrolyte is adjusted through a valve;
[0068] S5, electrolyzing the copper foil, and adding additives in the electrodeposition tank during electrolysis;
[0069] S6,...
