[0002] Nano coating refers to the advanced technology of nano non-toxic coating and nano coating technology with high scientific and technological content. This high-tech nano coating is not only non-toxic and harmless, but also can slowly release a substance to degrade harmful substances such as indoor formaldehyde and xylene. All traditional surface coating technologies can be used or slightly modified to achieve nano material composite coatings. The easy-to-clean, anti-fouling and wear-resistant nano protective coating for the surface of metal substrates is applied to the surface of metal substrates. However, the service life of metals can be easily reduced when exposed to sunlight, and because of the thermal conductivity of metals, it is easy to cause the temperature inside the metal to be higher. After the improvement of the utility model, a graphene layer is arranged at the inner position of the nano outer coating, a spectral reflection aluminum foil layer is arranged at the inner position of the graphene layer, and a cured adhesive layer is arranged at the inner position of the spectral reflection aluminum foil layer. The spectral reflection aluminum foil layer is bonded to the metal substrate through the cured adhesive layer, and the light passing through the nano outer coating will be mostly reflected by the spectral reflection aluminum foil layer, and the transmitted heat can also be quickly conducted to the surrounding environment due to the ultra-high thermal conductivity of the graphene layer. The improvement of the utility model can effectively reduce exposure to sunlight and accelerate heat loss, thereby effectively improving the service life of the metal base layer.
