Since the transportation cost of the whole glass cover is high, the production cost is high, and then the coating on the surface of the color steel tile 3 is protected in the glass protective cover 4 by using the raised sealing blocks 415, so that the coating is in a sealed state in the glass protective cover 4, and the single glass tile 41 is higher on the left and right sides than the arc-shaped flat glass sheet 413, so that the upper end of the whole color steel tile 3 is undulating, the rainwater can slide off without dead angle in rainy weather, the cleaning effect is good, and the undulating reflection and refraction surface is more, the reflectivity is higher, and the temperature difference between the inside and outside of the factory is larger, so that the color steel tile works well in the long-sun environment.

[0047] Further, the glass protective cover 4 is arranged on the upper end of the color steel tile 3, and the glass protective cover 4 does not contact the coating on the upper end of the color steel tile 3. Therefore, even in the case of high temperature and long sunshine, the coating will not contact the glass protective cover 4 when it softens due to high temperature, and the influence of external impurities, dust and rainwater erosion on the coating can be prevented.

[0048] Further, the gelation temperature of the coating is controlled to be 200°C, the gelation time is 180s-280s, the specific gravity of the coating is 1.2-1.7kg / m3, and the specific gravity of the coating changes within 1.2-1.7kg / m3 with the color, the particle size distribution D50 of the coating is controlled to be 37-41, the gelation temperature, time and specific gravity of the coating are limited, the yield rate of the coating in the coating process can be effectively improved, the requirements for environmental protection and energy utilization are higher and higher in China at present, paint is replaced by powder for environmental protection, energy saving and emission reduction, and the like is a trend, the graphene heat conduction layer 32 and the high reflection layer 33 are the coating of the color steel tile 3, the energy consumption of the manufacturer is reduced, environmental protection and no VOC emission are considered, and with the development of society and the advocacy of the government, the prospect is more and more broad.

[0049] Further, the graphene heat-conducting layer 32 uses, but is not limited to, titanium nickel yellow paint.

[0050] Working process: first, install the load-bearing base stone 1 at the required position, then fix the frame 2 on the upper end of the load-bearing base stone 1, then fix the color steel tile 3 on the frame 2, and set the glass protective cover 4 on the color steel tile 3. During installation, first, the installation protrusions are adaptively connected with the grooves 411 on the bracket 36, then the connecting slots 341 are adaptively connected with the buckles 414 for installation, the single glass tile 41 is spliced into a whole glass protective cover 4, and finally, the installation recesses are adaptively connected with the protrusions 412 at the closing position to ensure that the whole glass protective cover 4 is stably installed on the coating layer of the color steel tile 3 and does not contact the layer;

[0051] It is worth noting that the bottom layer of the coating on the color steel tile 3 is coated with a long glue layer 31. The long glue layer 31 has a longer particle diameter than length, has the effect of increasing adhesion of the bottom coating and increasing weather resistance of the surface coating, and can float up to improve the reflection efficiency of the glass crystal; then the graphene heat-conducting layer 32 is set. The graphene heat-conducting layer is a black body material that can avoid light transmission, heat absorption, and heat conduction, absorb wavelengths, and does not contain volatile compounds (VOC), reducing harm to the human body, ensuring that the interior temperature of the whole color steel tile 3 is more effective, saving energy, and suitable for placing in countries and weather with long sun exposure;

[0053] Finally, the glass protective cover 4 is arranged to protect the coating surface, because in the long sun area, the coating temperature in the glass protective cover 4 may rise to more than 80 DEG C, and the coating temperature is more than 80 DEG C, which may appear softening, if the coating is directly exposed to the outside at this time, the macromolecular structure in the whole coating is easily affected by the external interference, and the reflection efficiency of the coating is affected, so the glass protective cover 4 is arranged, which can not only reduce the contact between the coating and the outside, improve the weather resistance, but also the glass protective cover 4 adopts the transparent glass material, which can not only reduce the infrared reflection efficiency of the coating, but also improve the heat insulation performance of the whole color steel tile, and conveniently play the role of adjusting the internal temperature of the factory.

[0054] The whole glass protective cover 4 has no dead angle, is convenient to clean, and ensures high refraction and reflection efficiency, the installation of ups and downs increases the compression resistance, and the whole is formed by piece by piece splicing, the transportation cost is low, the coating of the whole color steel tile 3 is green and convenient to use, the investment cost is low, the weather resistance is excellent, the coating performance is excellent, the demand for product or coating replacement is reduced, the carbon emission is reduced, the recycling is used, the waste is little, the utilization rate is high, no waste residue, waste water and waste gas are produced.
