Description
Technical field
The utility model is related to screen with protection technical field of membrane more particularly to a kind of antiradar reflectivity of TAC base materials without coloured silk
Rainbow line hardens protective film.
Background technology
With the continuous upgrading of liquid crystal display resolution ratio, screen requires high transmittance, antiradar reflectivity with protective film, with full
The better visual experience of foot.And the protective film of current market, still based on PET base material, PET base material does cure process and the back of the body
During glue, since refractive index and the hardening bath and glue of own material cannot reach optical match, rainbow line phenomenon is serious, instead
The rate of penetrating reaches 12% or more, generates many dazzles, influences visual experience.
Utility model content
Technical problem to be solved in the utility model is in view of the above-mentioned deficiencies and provides a kind of high transmittance and low anti-
Penetrate protective film of the rate without rainbow line.
In order to solve the above technical problems, the technical solution adopted in the utility model is：It is a kind of using TAC as the low reflection of base material
Rate hardens protective film, including TAC base materials without rainbow line, clear in the coated on one side polyurethane acrylic resin of the TAC base materials
Paint forms one layer of anti-scraping coating, and the another side of the anti-scraping coating is bonded protective film, and the second face coating of the TAC base materials is high
Saturating OCA glue, forms OCA glue-lines after solidification, silicon release film is bonded in the another side of the OCA glue-lines, the anti-scraping coating
Refractive index is 1.47.
Preferably, the thickness of the TAC base materials is 40-80 μm, and the thickness of the anti-scraping coating is 3-6 μm, the OCA glue
The thickness of layer is 30-50 μm.
Preferably, the thickness of the protective film is 30-60 μm, and the thickness of the silicon release film is 25-50 μm.
The utility model additionally provides a kind of preparation side for hardening protective film without rainbow line using TAC as the antiradar reflectivity of base material
Method includes the following steps：
A, its material of TAC pre-processes：
Corona：The pretreatment that TAC base materials are passed through to 500Wmin/m2, increases its surface dynes value, facilitates coating coating；
B, it is coated with hardened layer：
Anilox roll coating method is selected, the polyurethane acrylic resin varnish paint that refractive index is 1.47 is coated on electric
On the TAC materials of dizzy processing, scratch resistant TAC materials are made；
C, OCA glue-lines are coated with
In the high OCA glue thoroughly of TAC base material another sides coating, using scraper or slot coated head, 30-50 μm of bondline thickness,
Through baking oven for drying solidification, finished product is made in the silicon release film of 25-50 μm of fitting.
Preferably, further include the another side fitting protective film in polyurethane acrylic resin coating in step B.
Preferably, the thickness of the TAC base materials is 40-80 μm；The thickness of the anti-scraping coating is 3-6 μm, protective film
Thickness is 30-60 μm.
The refractive index of PET base material is 1.63, the light-cured acrylic hardening of resin liquid or OCA in either present market
Glue is all difficult to reach, and TAC materials are 1.47-1.48, the refractive index with acrylic resin hardening bath and OCA currently on the market
It is close, it effectively reduces because of rainbow line and dazzle caused by refractive index difference.Therefore the utility model uses TAC materials,
The UV curing acrylic resins of matching refractive index close with its do hardened layer, then the low reflection of high transmittance is made in backsize OCA
Without rainbow line protective film.
In conclusion with the technical solution of the utility model, have the advantages that：1, the saturating of protective film is improved
Light rate；2, reflectivity is reduced, rainbow line is eliminated, effectively promotes visual experience.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model protective film.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, but does not constitute the limitation to scope of protection of the utility model.
