Description
Technical field
The present invention relates to a kind of optical thin film more particularly to coating system, a kind of nano-silver thread conductive film and its preparations
Method.The nano-silver thread conductive film shows for touch-control, big sun can the fields such as battery, LED illumination.
Background technology
Tin indium oxide ITO (ITO, Indium Tin Oxide) conductive film is current most widely used electrically conducting transparent membrane material
Material, but the brittleness of ITO materials and the high resistance of ito film make it be restricted in Flexible Displays and large touch application field.
In recent years, the substitute products of ITO conductive films continuously emerge, and wherein nano-silver thread conductive film is quickly grown, in some fields
It is applied.Nano-silver thread conductive film includes transparent base and covers nano-silver thread layer in substrate surface, nano-silver thread
It being distributed in nano-silver thread layer, each nano-silver thread mutually overlaps and conductive, and nano-silver thread highlights on the surface of nano-silver thread layer,
The surface of transparent base forms conductive layer.
There are many preparation methods of nano-silver thread conductive film, such as bat printing, transfer and direct coating method；Directly in basement membrane
Upper coating nano-silver thread conductive film is current main method, if Chinese invention patent application number is 201410188845.8,
Publication date is August in 2014 20, and patent name is " a kind of manufacturing method of high transmittance nano metal transparent conductive film "
Patent of invention shown in and Chinese invention patent application number be 201410229462.0, publication date is August in 2014 27,
Patent name is shown in the patent of invention of " a kind of production method of nano-silver thread transparent conductive film ".Buna is directly applied on basement membrane
The roll-to-roll coating method of rice silver wire conductive layer is formed by the processing steps such as unreeling, being coated with, dry and wind, production efficiency height,

On the other hand, nano-silver thread layer is coated with using aqueous masking liquid, is suitble to the hardness of the water-base resin used not
Height, directly using be easy is aoxidized by moisture and air, influence electric conductivity, thus nano-silver thread layer is applied again one layer it is ultraviolet
Photocuring protective coating.Conductive layer and protective layer are coated on the increasing that can cause surface scratches and point defect quantity in production at twice
Add, leads to production yield and quality decline.One the reason is that conductive layer not scratch resistance, because tension force is bad or film table when winding
Face absorption dust causes to scratch；Second is that although the environment of production conductive film is toilet, and even if grade reaches 100-1000 grades, sky
Between still have a certain amount of particle, when secondary coating, the dust of production environment can be adsorbed by unreeling the electrostatic of process generation, form point
Defect makes production yield and quality reduce.
