According to the estimates of the Chinese Academy of Engineering
the loss caused by corrosion in China is more than trillions of RMB every year Chinese Academy of Engineering. Corrosion damage is a common problem all over the world. Polyurethane coating plays an important role in the coating industry due to its excellent properties and is widely used in corrosion protection of materials. In order to further improve the corrosion resistance of the products
the researchers used different modification methods to prepare polyurethane anti-corrosive coatings with different functions. This article generalizes and introduces modification methods of polyurethane anti-corrosive coatings
which include Organic resin modification
nano material modification
corrosion inhibitor modification and microcapsule self-repairing modification. Meanwhile
the research progress of polyurethane coating in the field of anti-corrosion is introduced
and the future research direction and development trend are prospected.
