Base material is rushed at, so that occurring low-temperature sintering to make on base material between the metallic particles in the electrocondution slurry of spraying under the acceleration of high pressure
With so that metallic particles forms continuous print film layer structure, so that the electric conductivity of the conducting film prepared is higher.Further preferably
Ground, electrocondution slurry selects nanometer silver paste.Specialty, under corona effect, the polyvinylpyrrolidone on nano-silver thread surface is removed, with
Time nano-silver thread between occur low-temperature sintering effect, so can improve the electric conductivity of conducting film.
In the electrostatic spraying apparatus of this detailed description of the invention, electrocondution slurry is uniformly to fall at base by the way of electrostatic spraying
On material, it is only necessary to the amount of the electrocondution slurry that control is sprayed on base material just can control thickness, and the amount regulating electrocondution slurry can
With easily by the flow velocity of liquid, the walking speed of unwinding and rewinding system when the concentration of regulation electrocondution slurry dispersion liquid, spraying
Regulating, therefore the electrostatic spraying apparatus processing nesa coating of this detailed description of the invention comes real not against accurate machining accuracy
Existing specific thicknesses, the coating of enough accuracy, because without regard to processing component accurate especially, therefore equipment cost is greatly reduced.
The device selecting this detailed description of the invention is processed, and general cost is below 500,000.And existing accurate coating relies on precision
Coating head can be coated with out the coating of enough accuracy, therefore apparatus expensive, substantially 150～3,000,000.It is coated with additionally, accurate
During cloth electrocondution slurry, such as nano-silver thread, it has the draw ratio of superelevation, readily along the direction orientations of coating, causes
Being overlapped to form the inefficient of conductive network, electric conductivity is poor.The device of this detailed description of the invention is by electrostatic spraying mode then
Nano-silver thread as much as possible fully random distribution can be made on a transparent substrate, thus be overlapped to form conductive network efficiently, prepared
Nesa coating electric conductivity is more preferably.It addition, the device of this detailed description of the invention is also beneficial to improve the yield of product, prepared
The light transmission of product is also preferable, also can adapt to various complex surface, can realize long wide cut, volume to volume ground large-scale production.
As shown in Figure 6, for the nano-silver thread nesa coating using the electrostatic spraying device of this detailed description of the invention to prepare
Sample.It is seen that nano-silver thread is a kind of random distribution state spatially on a transparent substrate.Nano-silver thread is random
The overlap joint state of distribution so that the electric conductivity of prepared conducting film is relatively good.After tested, use four probe machines to record its sheet resistance to be
