A gas phase antirust paper for multiple metals and a preparation method thereof. The composite gas-phase slow-release layer comprises the following components in percentage by mass: 10-30% of sodium benzoate; 10-30% of 2, 6-dimethoxy 1, 4-benzoquinone; 10-25% of benzotriazole; 5-20% of 2, 4-di-tert-butyl-4-methylphenol; 10-20% of methyl phenyl carbamate; 5-15% of 2-methylpyrimidine; 10-30% of abietic acid amide borate compound; 10-30% fumed silica. The compound vapor phase corrosion inhibitor is fully fused and interacted under the regulation of a nonionic surfactant, namely abietic acid amide borate; the fumed silica can be used as a support body of the vapor composite corrosion inhibitor, so that the specific surface area of the fumed silica is greatly improved, the fumed silica can be fully volatilized to the metal surface to form a protective film, and the vapor antirust performance can be better exerted through the synergistic effect. |
