Problems solved by technology

However, the existing anti-corrosion coatings used in other technical fields have obvious deficiencies in performance when they are applied to facilities and equipment such as waterway amphibious vehicles and aircraft, which are mainly reflected in the fatigue resistance, corrosion resistance, weather resistance, and corrosion resistance of the existing coatings. Insufficient performance such as impact, insufficient adhesion to metal substrates and insufficient vibration resistance, resulting in short anti-corrosion time and insufficient durability of anti-corrosion coatings, which cannot meet the needs of equipment that needs to serve in harsh working environments

Description

technical field [0001] The invention relates to the field of coatings, in particular to a special salt-spray-resistant impact-resistant anti-corrosion coating. Background technique [0002] At this stage, facilities and equipment such as amphibious vehicles and aircraft have gradually become a development trend. They are mainly used for maritime patrol, anti-submarine, rescue, tourism, aerial photography and so on. However, because such cars and aircraft need to be in humid working environments such as the ocean for a long time, they will be affected by high salt spray, high humidity and heat, monsoons, rain and sea waves, and frequent water collisions, which are very easy to Lead to severe corrosion of amphibious vehicles, aircraft bottom structures and systems. Corrosion of structures and systems of amphibious vehicles and aircraft can cause structural damage and functional system failure, thereby increasing maintenance costs, reducing equipment life, and even endangering...
