Problems solved by technology

[0004] Although polyaniline has excellent anti-corrosion properties, its mechanical processing properties and compatibility with resins are poor, which limits its use.
Now the conventional methods of combining polyaniline with resin mainly include: ①Dissolution method: use a special solvent to dissolve and add it to the resin. This method will cause environmental pollution, poor construction conditions, and the expensive solvent will increase the cost shar

Description

technical field [0001] The invention relates to an environment-friendly polyaniline anticorrosion coating and a preparation method thereof. Background technique [0002] The loss caused by metal corrosion to human beings is staggering. According to statistics, the annual metal loss caused by corrosion in the world is as high as 20%-40% of the global metal production, and the economic loss is about 1 trillion US dollars. Practice has proved that the use of coatings for corrosion protection of metals is the most economical, practical and effective method. However, the current commonly used anti-corrosion coatings contain a large amount of organic solvents, which cause great pollution to the environment during the construction process and pose a huge threat to the health of workers; at the same time, commonly used anti-corrosion coatings are also rich in zinc, which not only consumes a lot of zinc resources, but also affects the health of workers. The environment is seriously ...
