Graphene fluoro-carbon metal paint and preparation method thereof

Abstract

The invention relates to a graphene fluoro-carbon metal paint and a preparation method thereof. The metal paint comprises a component A and a component B, wherein the component A comprises the following raw materials: 60-70 parts of fluoro-carbon resin, 5-10 parts of aluminum paste, 20-25 parts of a solvent, 0.1-1 part of graphene, 0.1-1 part of a dispersant, 0.5-1 part of an orientation agent, and 0.1-1 part of an anti-settling agent; and the component B is a curing agent with mass part of 6-7 parts. The method for preparing the metal paint comprises the following steps: weighing the raw materials according to the ratio, mixing graphene, fluoro-carbon resin and a part of the solvent, performing ultrasonic dispersion, adding the orientation agent, then performing mechanical stirring and dispersion; mixing the aluminum paste and the residual solvent, adding the dispersant, performing mechanical stirring and dispersion; then adding the dispersed aluminum paste in the dispersed graphene fluoro-carbon resin liquid, adding the anti-settling agent, and performing mechanical stirring and dispersion to obtain the component A of the metal paint, and taking the curing agent as the component B of the metal paint, and uniformly mixing the component A and the component B while in use. The metal paint has the advantages that 1) a coating has excellent anti-corrosive property; and 2) the coating conductivity is good, and the coating can be used for the occasions with electric conduction and heat radiation requirements.

Description

technical field [0001] The invention relates to a graphene fluorocarbon metallic paint and a preparation method thereof, belonging to the technical field of paint and preparation. Background technique [0002] Compared with traditional coatings, fluorocarbon metallic paint has better weather resistance due to the large number of high bond energy C-F bonds in the fluorocarbon molecular chain; Low, resulting in general anti-corrosion performance, and at the same time, the electrical and thermal conductivity of the coating is insufficient. In order to better exert the excellent properties of fluorocarbon resins and expand the application range of fluorocarbon resins, it is necessary to modify them. [0003] Graphene is a new type of two-dimensional material with a single-layer sheet structure composed of carbon atoms, and its excellent electrical, thermal and mechanical properties have attracted widespread attention. The graphene of the lamella structure has a good shielding ...
