A graphene-modified chromium-free coating Dacromet

The present invention discloses a graphite-modified chromium-free Dacromet coating comprising zinc powder, aluminum powder, film formers, solvents, adjuvants and the Dacromet coating with graphene fillers added, each group points Dacromet coating weight percentages are 10-20% zinc, 2-10% aluminum, 2-20% film forming agent, 40-60.8% solvent, 0.1 to 5% additives, graphene 0.001 0.1 to 5% -20% of the filler. Dacromet chromium-free coating of the present invention is a graphite-modified hardness, adhesion than conventional Dacromet have been greatly improved, the hardness of the coating up 7H, such that the coating has a better wear performance; reduce energy consumption and improve the conductivity of the coating, and further improve the corrosion resistance of chromium-free Dacromet corrosion resistance coatings; material of the present invention is free from the environment, harmful substances, fundamentally eliminate the source of contamination.
