Abstract

The present invention discloses a graphene-modified Dacromet coating material, which comprises, by weight, 15-30% of zinc powder, 1-10% of aluminum powder, 2-20% of a film forming agent, 27-50% of a solvent, 1-5% of an auxiliary agent, 0.001-20% of graphene, and 1-5% of a filler. According to the present invention, compared with the traditional Dacromet coating material, the graphene-modified Dacromet coating material of the present invention provides substantially-increased hardness and substantially-increased adhesion, wherein the hardness of the coating of the present invention can be 7H so as to make the coating have good wear performance; and the energy consumption is reduced, the conductivity of the coating is increased, and the corrosion resistance of the Dacromet coating material is further increased.

Description

technical field [0001] The invention belongs to the technical field of metal anticorrosion, and relates to a dacromet paint, in particular to a graphene-modified dacromet paint which improves the friction resistance and corrosion resistance of the coating. Background technique [0002] Corrosion of metals is very common, and the loss to the national economy is very huge. Dacromet technology is a new metal surface anti-corrosion technology developed in recent years. It was invented by the American DIAMONDSHAMROCK company in the late 1960s. The biggest advantage of Dacromet coating is that it has excellent corrosion resistance, and its corrosion resistance can be improved by 7-10 times compared with the traditional galvanized surface treatment process; the coating has no hydrogen embrittlement, especially suitable for high-strength Stressed parts; the coating has high heat resistance, and the heat resistance temperature can reach 450°C, especially suitable for high-strength c...
