Abstract:Corrosion has become one of the main culprits that harm the world economy and constitute a major accident, so how to solve the problem of corrosion is the difficulty we must overcome at present. As a kind of anti-corrosion material, waterborne polyurethane coating is non-toxic, tasteless, safe and environmentally friendly, but the anti-corrosion performance still needs to be improved. In order to further improve the anti-corrosion performance of products, researchers use different modification methods to prepare waterborne polyurethane anti-corrosion coatings with different functions. This paper mainly introduces the modification of Waterborne Polyurethane Coatings by several commonly used modification methods such as nano materials and self-healing, and prospects the future research direction and development trend.
