The invention relates to the technical field of multi-layer solar film preparation, in particular to a nano
titanium nitride solar film and a preparation method thereof.The nano
titanium nitride solar film comprises a release film layer, an
adhesive layer, a substrate layer, a functional core layer, an
ultraviolet-proof layer and a wear-resistant explosion-proof layer which are sequentially compounded from bottom to top; the release film layer is a
polyethylene glycol terephthalate release film with the thickness of 25-30 [mu] m, and the surface of the release film layer is coated with an organic
silicon release agent with the thickness of 3-5 [mu] m. According to the nano
titanium nitride solar film, a nano
titanium nitride and
indium tin oxide composite
system is adopted, a double-target synchronous
sputtering process is combined, high
infrared reflection efficiency is guaranteed, nano
titanium nitride dispersion liquid and an anti-aging compound are further introduced, aging of an
adhesive layer is remarkably delayed, degumming and color
fading are avoided, meanwhile, the rheological property and
bonding strength are optimized, and the service life of the solar film is prolonged. The
coating is suitable for large-area spraying to be attached to curved glass, the construction hollowing rate is lower than 0.3%, the edge warping risk is remarkably reduced, and dependence on manual operation is reduced.
