Description

technical field

[0001] The invention belongs to the technical field of graphene anticorrosion coatings, in particular to a preparation method of graphene zinc-containing epoxy anticorrosion coatings. Background technique

[0002] Corrosion causes huge economic losses every year all over the world. Among many anti-corrosion measures, anti-corrosion coating is one of the most economical and effective methods. At present, the anticorrosion coatings used in the field of heavy anticorrosion are mostly epoxy zinc-rich primers. In practical applications, epoxy zinc-rich primers with a zinc content of more than 80% are mostly used. However, excessive zinc content will damage the health of users and is not friendly to the environment. Therefore, researchers are also working hard to find ways to reduce the zinc content while ensuring anti-corrosion properties.
