Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an anticorrosion liquid for environment-friendly metals. Background technique [0002] Metal anti-corrosion is to protect the metal surface that is easy to rust and prolong its service life. The commonly used methods are physical anti-corrosion, electrochemical anti-corrosion and chemical anti-corrosion. However, traditional anti-corrosion products have different problems, especially the anti-corrosion time of black iron oxide film. Not long enough, not ideal enough. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly metal anticorrosion solution aiming at the deficiencies of the prior art. [0004] The technical scheme adopted in the present invention is as follows: a kind of environment-friendly anticorrosion liquid for metal is made of the following raw materials in parts by weight: 50 parts of silane coupli...
