Corrosion-resistant gas-phase rust inhibitor, preparation method thereof and gas-phase rust-resistant diaphragm capsule

The invention belongs to the technical field of metal corrosion-resistant materials, and particularly relates to a corrosion-resistant gas-phase corrosion inhibitor, a preparation method thereof and a gas-phase corrosion-resistant film box. The corrosion-resistant gas-phase corrosion inhibitor comprises the following raw materials: organic amine, an azole derivative, molybdate and an alcohol-water mixed solvent, the structural formula of the azole derivative is shown in the claims, and the high-corrosion-resistant gas-phase corrosion inhibitor is a solution of a compound of three corrosion inhibitors including the organic amine, the azole derivative and the molybdate. Wherein the nitrogen azole derivative is a volatile liquid macromolecule containing fragrance, a nitrogen azole ring structure with large steric hindrance and amido are arranged on the nitrogen azole derivative, an efficient anti-corrosion effect can be obtained when the nitrogen azole derivative is compounded with organic amine and a molybdate
