Description

technical field [0001] The invention belongs to the field of metal material maintenance of steel structures, in particular to an ultraviolet-excited fluorescent normal temperature curing phosphate anti-corrosion coating and a preparation method thereof. Background technique [0002] It is the most common electrochemical corrosion phenomenon of metals that the metal contacts the medium in the surrounding environment and undergoes chemical reaction. Since the metal surface is in contact with the surrounding medium (such as moist air, electrolyte solution, etc.), the metal anodic dissolution process will occur at the contact interface. At the same time, there is also a corresponding cathodic process, which constitutes a spontaneous corrosion battery, which makes the metal anode dissolve continuously, thereby causing metal corrosion. According to the survey, the global economic loss caused by metal corrosion accounts for about 4% of the total GDP each year, and the annual loss o...
