Abstract

The invention discloses a graphene super anticorrosive powdery paint, and a preparation method thereof. The graphene super anticorrosive powdery paint is prepared from 35 to 45 parts of polyphenol type glycidyl ether epoxy resin, 25 to 35 parts of hydantoin epoxy resin, 10 to 12 parts of graphene particle, 15 to 18 parts of glass bead, 2 to 3 parts of 2-methylimidazole, 8 to 10 parts of mica powder, 2 parts of a levelling agent, 5 to 8 parts of iron red, and 0.5 part of benzoin. The preparation method is capable of dispersing graphene in the graphene super anticorrosive powdery paint to be uniform, and the obtained graphene super anticorrosive powdery paint is excellent in effects.

Description

technical field [0001] The invention belongs to the technical field of powder coatings, in particular to a graphene super anti-corrosion powder coating and a preparation method thereof. Background technique [0002] Super anti-corrosion coatings have always been one of the important branches of coatings and are widely used in industrial production. In the production of the national economy, the use of a large number of metal products makes the anti-corrosion requirements of equipment very high, and the market demand for anti-corrosion coatings continues to rise. Most of the existing anti-corrosion coatings are liquid coatings, and liquid coatings often contain harmful and toxic solvents. polluted environment. [0003] Powder coating is a new, solvent-free, easy-to-operate, 100% solid powder-like environmentally friendly coating. Powder coating has high utilization efficiency, less waste, energy saving and environmental protection; graphene is a two-dimensional crystal forme...
