Abstract

The present invention provides a heavy-duty graphene primer for ocean ships and a preparation method thereof. The primer is prepared by mixing a plurality of antirust pigments, fillers and solvents, such as modified epoxide resin, additives, nanoscale graphene, zinc powder and diphenyl guanidine chromate, with a modified amine and a polyamide, and has long-term corrosion resistance and also advantages unmatched by other graphene primers, including wide scope of application, convenience in construction, excellent electrical conductivity, and good self-repair performance and hydrophobic and oleophobic properties of the coating. In addition, the primer is air-dried at normal temperature, thereby saving energy and facilitating industrialization thereof.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to the field of industrial anti-corrosion coatings, in particular to a graphene heavy-duty anti-corrosion primer for marine ships and a preparation method thereof. Background technique [0002] Due to the high concentration of electrolytes, seawater has a stronger rusting and corrosion effect than freshwater. In the harsh marine environment, the hull steel is prone to corrosion or rust, which will seriously affect the overall performance, resulting in a decrease in the strength of the hull, local corrosion damage, and a decrease in navigation speed. In order to solve the above problems, the common way is to apply anti-corrosion coatings to marine ships. As a metal anti-corrosion coating, organic coatings are low in cost, easy to use, have low requirements on the substrate, and have a good protective effect. [0003] For anti-corrosion coatings, traditional protective coatings are...
