The direction that field technique personnel make great efforts.
Summary of the invention
The utility model aim is to provide rupture pressure disc in a kind of easy heavy industry for Curved screen, which fits in
Curved surface screen surfaces have the characteristic that heavy industry is easy initial stage, docile was bad to achieve the effect that protect Curved screen.
In order to achieve the above objectives, the technical solution adopted in the utility model is: preventing in a kind of easy heavy industry for Curved screen
Quick-fried film, it is characterised in that: including the first PE film protective layer, the UV light solidifying coating, pet layer, optics being successively bonded from top to bottom
Glue-line, release film separation layer and the 2nd PE film protective layer；
The UV light solidifying coating is coated on the surface of pet layer, and the first PE film protective layer is set to the painting of UV photocuring
Layer is opposite to each other in the one side of pet layer, and the release film separation layer is fitted by optical adhesive layer and pet layer another side, the optics
The surface that glue-line is contacted with release film separation layer is provided with the vent grooves of supplied gas discharge, the 2nd PE film protective layer setting
In release film separation layer opposite to each other in the one side of optical adhesive layer.
Further improved technical solution is as follows in above-mentioned technical proposal:
1. in above scheme, the optical adhesive layer with a thickness of 20 μm ~ 30 μm.
2. in above scheme, the release film separation layer is that fluorine moulds release film or non-silicon release film.
3. in above scheme, the depth of the vent grooves and the thickness proportion of optical adhesive layer are 1:(1 ~ 5)；It is described logical
Gas groove arrangement mode is array.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
1. the utility model has preferable for rupture pressure disc in the easy heavy industry of Curved screen, surface UV light solidifying coating
High temperature resistance and flexibility, the rupture pressure disc for being coated with above-mentioned UV light solidifying coating are not susceptible to crack or melt after thermocompression forming
The case where change, product yield are high；And the coating and ink compatibility are good, with ink solidification layer excellent adhesion, can be made into
The material of various colors or gradient color meets various customer demands.
2. utility model, for rupture pressure disc in the easy heavy industry of Curved screen, the initial stage of optical cement and camber display screen used is viscous
It is low to tie power, 500gf/in or so is sticked to the first of glass, even if contraposition patch is uneven when pasting with screen glass, after can also taking off
Re-posted rupture pressure disc, while also avoiding bonding too strong the problem of leading to glass breaking due to initial stage, viscosity is got higher after placing for 24 hours,
To glass test viscosity in 1800gf/in or more, can be firmly bonded with camber display screen；In addition, optical adhesive layer with it is release
The vent grooves that the surface setting supplied gas of film separation layer contact is discharged, have automatic ventilating function, so that the interior rupture pressure disc pastes
More docile simplicity.
Detailed description of the invention
Attached drawing 1 is the utility model for explosion-proof membrane structure diagram in the easy heavy industry of Curved screen.
In the figures above: 1, the first PE film protective layer；2, UV light solidifying coating；3, pet layer；4, optical adhesive layer；41, it ventilates
Groove；5, release film separation layer；6, the 2nd PE film protective layer.
Specific embodiment
The utility model is further described below with reference to embodiment:
Embodiment 1: rupture pressure disc in a kind of easy heavy industry for Curved screen, including the first PE film being successively bonded from top to bottom
Protective layer 1, UV light solidifying coating 2, pet layer 3, optical adhesive layer 4, release film separation layer 5 and the 2nd PE film protective layer 6；
