Description

technical field [0001] The invention relates to a coating, in particular to a graphene-modified fluororesin coating which improves the strength of the fluororesin coating, the adhesion to the base material, the friction resistance, the impact resistance, the corrosion resistance, and the thermal conductivity. [0002] Background technique [0003] Fluorine resin coating refers to the coating with fluorine resin as the main film-forming substance, also known as fluorocarbon paint, fluorine coating, etc. Among all kinds of coatings, fluororesin coatings have greater electronegativity and strong carbon-fluorine bond energy due to the introduction of fluorine elements, and their weather resistance, heat resistance, low temperature resistance, and chemical resistance are greatly improved compared with traditional coatings. After decades of development, fluorine coatings have been widely used in various fields such as construction, chemical industry, electrical and electronic ind...
