A kind of anti-corrosion protective cover and preparation method thereof

Abstract

The invention relates to an anti-corrosion protective cover and a preparation method thereof. The structure of the protective cover sequentially includes a surface layer, a middle layer and an inner lining layer; the surface layer is a waterproof and breathable polyester fabric material, which blocks the entry of external moisture, and at the same time The air-permeable structure can allow the water vapor within the packaging range of the material to radiate outwards to reduce the condensation of internal water vapor, reflect the sun's rays, and block the damage of UV rays; the middle layer is a high-barrier gas-phase anti-rust film, which isolates the contact of corrosive substances and prevents corrosion. To achieve the effect of anti-corrosion, reduce the occurrence of corrosion of protective parts; the inner lining layer is made of vapor phase anti-rust non-woven fabric, which not only has good protection performance for the paint surface and high-gloss surface of the equipment, but also reduces the damage of the paint surface and electroplating surface , has a certain anti-skid function, and can further improve the corrosion resistance. Therefore, the anti-corrosion protective cover of the present invention is waterproof, breathable, environmentally friendly and pollution-free, light in weight, good in ultraviolet resistance, good in anti-corrosion performance, and high in strength.

Description

technical field [0001] The invention belongs to the technical field of protective packaging materials, and in particular relates to an anti-corrosion protective cover and a preparation method thereof. Background technique [0002] The corrosion problem of aircraft in active service in my country, especially aircraft that often fly in coastal areas, is more prominent. The reason is mainly due to the high humidity in the coastal areas, the sea fog, the high salt content in the atmosphere, and the corrosion aggravated by industrial pollution. For example, when the aircraft is parked, the lower walls of the fuselage and wings are closer to the ground, and water vapor on the ground evaporates and condenses on the lower walls, making the fuselage-wings in a humid environment for a long time, and water, condensation and water vapor enter the non-sealed Riveting gaps, resulting in severe corrosion. [0003] In the prior art, the local application of corrosion inhibitors on aircraf...

Problems solved by technology

[0005] When parked in the outfield and hangar, in order to further strengthen the anti-corrosion protection of aircraft landing gear, air intake and tail spray and other components, extend the maintenance cycle when the aircraft is parked in the outfield, and reduce the workload of corrosive maintenance, it is currently used in the navy The anti-corrosion protective cover materials of aircraft are mostly heavy-duty waterproof covers, such as waterproof canvas, etc., which have defects such as airtightness, heavy weight, non-softness and poor anti-corrosion effect
