Abstract

The invention discloses a copper foil anti-oxidation treating fluid, a preparation method of the copper foil anti-oxidation treating fluid and copper foil anti-oxidation treating equipment. The copper foil anti-oxidation treating fluid comprises the following raw material ingredients by weight: 0.05-0.1 g / L hydroxybenzotrizole (HBTA), 0.02-0.05 g / L 2-mercaptobenzothiazole (MBT), 0.1-0.5 g / L of silver nitrate, 0.1-0.5 g / L sodium molybdate, 0.05-0.1 g / L phosphoric acid, 0.5-3 g / L boric acid and the balance of pure water. The copper foil anti-oxidation treating fluid can prevent water washing, reduces the water treatment cost, does not contain such harmful substances to the environment as hexavalent chromium, and meets the demand for environmental protection; an anti-oxidation and anti-passivation film is stable under the high-temperature condition and does not contain zinc metal; and such unstable problems as resistance reduction of a copper foil are solved. A liquid inlet of an anti-oxidation treatment groove of the copper foil anti-oxidation treating equipment is positioned above one end of the feeding side of a copper foil roller, so that two surfaces of the copper foil can be subjected to full anti-oxidation treatment.

Description

Technical field [0001] The invention relates to an anti-oxidation treatment liquid, more specifically to a copper foil anti-oxidation treatment liquid and a preparation method and equipment. Background technique [0002] As the main electronic material of PCB and lithium battery, electrolytic copper foil affects the development direction of the electronic field to a certain extent. With the development of new energy vehicles, lithium batteries have become the main power of new energy vehicles and serve as the negative electrode of lithium batteries. The electrolytic copper foil of the carrier has also been greatly developed, and the thickness has been developed from the previous 12μm and 10μm to the current 8μm and 6μm. To increase the capacity of lithium batteries per unit volume and mass. [0003] The excellent electrical conductivity, tensile strength, surface roughness and other properties of battery copper foil are suitable as negative electrode carriers for lithium batteries...
