Abstract

The invention relates to a production process of nano-silver wire transparent conductive film, comprising the following steps: (1) base material preparation: the selected base material is a PET base, and the prepared PET base is hardened; (2) coating Cloth the configured coating nano-silver wire coating solution and protective glue coating solution: apply the configured nano-silver wire coating solution and protective glue coating solution to the PET film base through coating equipment respectively; (3 ) Drying: drying the coated film; (4) Winding: winding the finished product. The process of the invention can effectively improve the good rate of the nano-silver wire conductive film, and accelerate the substitution of the nano-silver wire conductive film for ITO.

Description

technical field [0001] The invention belongs to the technical field of producing transparent conductive films, and in particular relates to a production process of nano-silver wire transparent conductive films. Background technique [0002] With the shipment area of ​​domestic capacitive screens exceeding 4 million square meters in 2013, the demand for ITO conductive glass exceeded 3.6 million square meters, and the demand for ITO PET conductive film exceeded 1.4 million square meters. From the cost analysis of upstream materials in the touch screen industry, ITO materials account for about 40%. And with the development of the touch screen industry, the demand for ITO materials will increase. As the rare metal indium required for ITO materials, not only the price will continue to rise, but there will be a danger of running out. [0003] Nano-silver wire (SNW, silvernanowire) technology is to smear nano-silver wire ink material on PET substrate or glass substrate, and then u...
