▎ 摘　　要

NOVELTY - Electrolytic copper foil oxidation-proof liquid comprises organic polymer, inorganic film-forming auxiliary agent and organic/inorganic acid additive. USE - The liquid is useful in electrolytic copper foil (claimed). ADVANTAGE - The oxidation-proof liquid does not contain heavy metal without water washing and electrifying. The method is simple; belongs to polymer organic-inorganic composite anti-oxidation liquid and improves the performance of electrolytic copper foil high temperature resistance and oxidation resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing electrolytic copper foil oxidation-proof liquid.
