Description

Technical Field

[0002] In the prior art, many environmental protection equipment are exposed to wind and rain for a long time, and the anti-corrosion performance of the equipment surface is required to be extremely high; there are many means to prevent the corrosion of metal materials, such as the use of corrosion-resistant metal materials, cathodic protection, corrosion inhibitors and metal protective coatings. Practice has proved that among the above metal anti-corrosion methods, the use of environmentally friendly anti-corrosion coatings to protect easily corroded metal materials is the most economical, effective and widely used anti-corrosion method. Conventional anti-corrosion coatings play an anti-corrosion role on metals under general conditions, thereby increasing the service life of non-ferrous metals; however, conventional anti-corrosion coatings cannot be used in relatively harsh corrosive environments, and it is difficult to meet the user's demand for the anti-corrosion ability of coatings.
