Embodiment Construction
[0014] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0015] like figure 1 As shown, a scratch-resistant solar backsheet includes a PET substrate 3, one side of the PET substrate 3 is connected to the weather-resistant layer 1 through the adhesive layer 2, and a scratch-resistant and wear-resistant coating 5 is arranged on the upper surface of the weather-resistant layer. The other end of the PET substrate 3 is connected to the weather-resistant adhesive layer 4 through the adhesive layer 2; the scratch-resistant and wear-resistant coating 5 is a fluororesin coating modified by a highly dispersed nanoporous gas phase SIO2 material, and the fluororesin coating is poly Vinylidene fluoride, polychlorotrifluoroethylene, polytetrafluoroethylene or copolymers of tetrafluoroethylene and ethylene. The above-mentioned anti-scratch and wear-resistant coating 5 has a thickness of 1-30 μm. The thicknes...
