Description

Technical Field

[0001] The utility model belongs to the technical field of anti-rust paper, and in particular relates to a slow-release anti-rust paper. Background Art

[0002] The carrier of rust-proof paper is rust-proof base paper. After being coated with VCI (vapor corrosion inhibitor) liquid, VCI will be continuously and slowly released from kraft paper in an appropriate space, forming a saturated gas layer in a relatively closed space, thereby forming rust-proof protection for metal materials in the environment. The varieties of rust-proof paper include bleached type, unbleached type; coated type, wrinkled type and coated wrinkled type, etc., and different VCI grades are used for different metals. The vapor phase rust-proof packaging technology of rust-proof paper is a technology that uses vapor phase corrosion inhibitor (volatile corrosion inhibitor) to treat metal products with rust in a sealed packaging container. Vapor phase corrosion inhibitor is a substance that can slow down or completely stop the destruction process of metal in corrosive media. It is volatile at room temperature. In a sealed packaging container, the slow-release gas volatilized or sublimated in a very short time can fill every corner and gap in the entire packaging container, and adsorb on the surface of metal products at the same time, thereby inhibiting atmospheric corrosion of metals. Metallurgical products, such as electronic appliances, auto parts, hot and cold rolled steel plates, coated and plated plates, rollers, metal wires, etc., are usually protected from rust by packaging paper containing corrosion inhibitors during storage and transportation to prevent corrosion from the natural environment.

[0003] At present, most of the existing slow-release anti-rust papers have simple structures and are easily damaged by external influences during long-term storage and use, such as being crushed or torn, which reduces the use effect. Utility Model Content
