Problems solved by technology

At present, many buried metal pipelines are corroded due to microorganisms. Adding microbial inhibitors to the coating can reduce the metal corrosion caused by microorganisms. However, if the microbial inhibitors are not coated, they can be directly added to the coating. layer, the antibacterial effect of the coating will not be effective for a long time

Description

technical field [0001] The invention relates to a polyaniline / manganese trioxide / epoxy resin ternary composite double anticorrosion coating and a preparation method thereof, belonging to the technical field of anticorrosion coating preparation. Background technique [0002] The economic losses caused by metal corrosion every year in the world are immeasurable, especially high-risk metal pipelines are facing serious corrosion and safety problems. For high-risk metal pipelines, anti-corrosion coating combined with cathodic protection is mainly used for anti-corrosion protection, and pipeline anti-corrosion coating is one of the key technologies for pipeline protection. Impact resistance and other properties prevent the entry of moisture, oxygen and corrosive media in the surrounding environment, so as to achieve the purpose of anti-corrosion. In addition, since most high-risk pipelines are buried pipelines, in addition to the moisture and oxygen in the soil, microorganisms in...
