AI Technical Summary
Technical Problem
Graphene is difficult to disperse in coatings, which reduces the water resistance of the paint film and affects the anti-corrosion effect.
Method used
By using grafted and modified graphene and modified fillers, epoxy resin slurry is prepared through a specific process to form a dense coating, thereby improving adhesion and corrosion resistance.
Benefits of technology
The prepared coating has excellent anti-corrosion properties, good component compatibility, forms a dense coating, improves adhesion, and significantly enhances the anti-corrosion effect.
