Embodiment 1
[0034] A kind of production method of nano-silver wire transparent conductive film, comprises the following steps:
[0035](1) Substrate preparation: apply the prepared hardened coating solution on the PET film base. In terms of weight percentage, the main components of the hardened layer coating solution are: 7% pure acrylic resin, 11% ten-functional polyurethane resin %, 20% of difunctional polyurethane resin, 6% of lauric acid acrylate, 6% of methyl benzoylformate, 50% of methyl ethyl ketone; the film base is hardened; the hardness of the non-nano silver wire coated surface of the PET film base is More than 1H; light transmittance 92%, haze ≤ 0.7%, thickness of PET film base is 100μm, dyne value of coating surface ≥ 50, no cracks on the surface after hot pressing at 190°C and 5Mpa for 30 seconds; the prepared The PET film base is placed on the supply rack;
[0036] (2) Coating nano-silver wire coating solution and protective glue coating solution: the configured nano-silve...
