The graphene fluorocarbon energy-saving coating comprises the following raw materials in parts byweight: water-based fluorocarbon emulsion, graphene, a film-forming aid, an ultraviolet absorbent, a leveling agent, algaecide and deionized water; and during preparation, the raw materials are addedinto a stirring machine sequentially and are dispersed while being stirred uniformly. The graphene and the fluorocarbon are combined, so that better heat-dissipating effect and adhesive force are achieved; the mass proportion of the mixed solvent and the aid is reasonable, so that the coating has high heat-conducting coefficient, high radiation heat-dissipating coefficient and good heat-dissipating effect; in addition, the coating has the advantages of high weather resistance, anti-pollution capacity, heat-insulating property, high heat reflecting property, high strength, flexibility, anti-mildew and anti-alga properties, fluent construction process, good construction effect and beautiful wall surface.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a graphene fluorocarbon energy-saving coating and a preparation method thereof. Background technique [0002] Graphene is a newly discovered nano-carbon material with only one carbon atomic layer in recent years. It has low density, weak chemical activity, fast heat conduction speed, high specific surface area and large infrared radiation rate. It has an important application prospect as a heat dissipation coating. However, the easy stacking of graphene leads to poor dispersion and increased difficulty in post-processing, so that it cannot show the intrinsic excellent characteristics of graphene.

However, the easy stacking characteristics of graphene lead to poor dispersion and increased difficulty in post-processing, thus failing to show the intrinsic excellent characteristics of graphene.

[0003] The prior art with the Chinese patent announcement number "103131274" disclosed a fluororesin heat-dissipating coating and its preparation method on June 5, 2013. Although the method uses carbon nanotubes to improve the problem of poor mixing of heat-conducting materials, it uses electronic Transfer-type organic compounds greatly increase the thermal radiation rate, but ignore the thermal conductivity of the material, which is not conducive to the heat exchange between the radiator substrate and the coating, thereby reducing the heat dissipation effect

[0004] The existing technology with the Chinese patent announcement number "102964972" disclosed a composite enhanced heat dissipation coating containing graphene or graphene oxide and its preparation method on March 13, 2013. The heat dissipation coating prepared by this method has a high infrared emission rate. , up to 0.96, but the heat-dissipating coating prepared by this method is complicated in process, with many processes, it is difficult to implement industrialization, and the cost is high
