Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features, and in the description of the invention, "a number" or "a number" means two or more unless explicitly specified otherwise.
The utility model provides a flexible OLED lighting panel's encapsulation protective layer, includes sets up in the cathode aluminium membrane 65 on OLED64 surface, inorganic zinc aluminium silicate coating 66 has been printed on cathode aluminium membrane 65, inorganic zinc aluminium silicate coating 66 has printed insulating layer 67 on.
As shown in fig. 1, the overall structure of the flexible OLED64 lighting panel in this embodiment is, from bottom to top, a flexible glass substrate 61, an anode 62, an insulating frame 63, an OLED64, a cathode aluminum film 65, an inorganic zinc aluminum silicate coating 66, and an insulating layer 67.
Preferably, the thickness of the cathode aluminum film 65 is more than 0.5um, and the thickness of the inorganic zinc aluminum silicate coating 66 is more than 10 um.
The inorganic zinc-aluminum silicate coating 66 in this embodiment is formed by printing an inorganic zinc-aluminum silicate coating, which is mainly formed by mixing an adhesive and zinc powder and aluminum powder.
The lithium silicate system binder can be self-cured at room temperature, so it has the best corrosion protection effect, its coating has waterproof performance after several hours, and it has little efflorescence and high adhesive strength, but because of the high price of lithium silicate, it is mainly used at present and is mixed with potassium silicate, and chinese patent 2013105854526 discloses a water-based inorganic silicate binder and its preparation method.
One of the main functions of the binder system is to suppress as much as possible the dissolution of zinc and the formation of white rust, wherein one possible solution is to add aluminium powder, which greatly suppresses the reduction of the cathodic oxygen during corrosion, and the reduction of the cathodic current leads to a corresponding reduction of the anodic 62 current, i.e. less dissolution of zinc, which explains why the addition of aluminium improves the white rust resistance.
The cathode aluminum film 65 with the thickness exceeding 0.5um can basically cover the particle dust on the OLED64 (the dust is removed by the organic light emitting diode)Particulate dust is generally less than 0.3um), dense Al is formed on the surface immediately after the surface aluminum contacts air2O3The film ensures that the lower aluminum is not oxidized, and the defects of the large cathode aluminum film 65 can be used as a packaging layer by coating the inorganic zinc aluminum silicate coating 66 to isolate water and oxygen.
The inorganic zinc aluminum silicate coating 66 is one of all corrosion resistant coatings with the longest durability, and the service life can be as long as 20 years to 50 years.
Interlayer protection is the primary mechanism for long-term corrosion protection of most zinc powder primers because its cathodic protection effect is extremely limited. In this case, it is conceivable that the protective mechanism is to block possible micro-pores or cover various damaged surface areas by the zinc corrosion products formed, thereby preventing water oxygen from contacting the surface of the workpiece 6.
In the preferred inorganic zinc aluminum silicate coating of this embodiment, zinc is a zinc sheet, the zinc sheet is used to replace zinc powder, there are gaps between zinc powders, moisture can easily enter vertically from the gaps, and due to the overlapping of zinc sheets, moisture can enter around many bends, so the anti-permeability is greatly improved, the diffusion path from the coating surface to the workpiece 6 becomes very long, and as a result, the anti-corrosion protection time of the workpiece 6 surface can be prolonged.
The inorganic zinc aluminum silicate coating 66 replaces the traditional organic-inorganic multilayer staggered film packaging structure, so that expensive low-temperature vacuum CVD coating equipment is omitted, and the equipment investment cost is greatly reduced.
