Description

technical field [0001] The invention relates to the field of antibacterial and anticorrosion coating products, in particular to a graphene-modified antibacterial and anticorrosion coating. Background technique [0002] The annual economic loss caused by corrosion in the world accounts for about 4% to 5% of GDP, of which marine corrosion accounts for 1 / 3, which hinders the development of marine economy. On average, large ships need to be docked for antibacterial and anticorrosive coating every 5 years It consumes a lot of anti-corrosion and antibacterial materials, which also delays the normal operation of ships, as do other marine facilities; there are also granaries closely related to our lives, most of which have special metal plates, pipes, It is composed of materials such as concrete structure, and has strict requirements for antibacterial and anti-corrosion. [0003] At present, many antibacterial and anticorrosive materials with excellent performance on the market con...
