Abstract
A capsule type gas phase rust-proof powder belongs to the technical field of rust-proof powder. The capsule wall film is 50-100 μm thick, and the gas phase rust-proof powder is composed of the following raw materials in parts by weight: 5-8 parts of o-phenylenediamine, 15-25 parts of sodium carbonate, 3-6 parts of hexamethylenetetramine, 15-35 parts of absolute ethyl alcohol, 20-30 parts of molybdate, 6-12 parts of sulfosalicylic acid, 25-35 parts of molybdate, 3-6 parts of triethanolamine and 10-20 parts of distilled water. The gas-phase rust-proof powder is wrapped by the water-soluble capsule wall, so that volatilization and loss of the gas-phase rust-proof powder caused by the influence of the external environment in the process of storage or use are avoided. When the relative humidity in the air gradually reaches 70%, the water-soluble capsule wall is degraded and destroyed by the water vapor in the air, and the gas-phase rust-proof particles of the gas-phase rust-proof powder can be volatilized to immediately play a rust-proof role, so that the method has the characteristic of quick reaction. When the capsule walls with different film thicknesses are degraded by water vapor, the required time is different, and the capsule type gas phase rust-preventive powder with different film thicknesses can be placed together to realize the continuous protection of an overlong period.
