The present invention relates to the technical field of solar back plates, and in particular to a fluorocarbon coating, a fluorocarbon coating solution and a transparent solar back plate. In order to solve the problem in which existing transparent solar back plates have high water vapor transmittance, provided in the present invention is a transparent solar back plate. According to weight percentage, the fluorocarbon coating comprises 20%-40% fluorocarbon resin, 20-40% titanium dioxide, 2%-5% matting powder, 0.3%-0.6% of an additive, 30%-50% of an adhesion promoter and 5%-8% isocyanate. The transparent solar back plate comprises in sequence from top to bottom: a white grid fluorocarbon coating, a transparent PO film, a first adhesive layer, a substrate, a second adhesive layer and a fluorine film layer. The transparent solar back plate provided by the present invention may effectively reduce the water permeability index of the entire back plate. |
