Fruit is poor, is easy to appear the phenomenon that rebound falls off.
Utility model content
In view of the above deficiencies, the utility model aim is to provide a kind of reasonable in design, using composite construction, reduces
The stiffness of material entirety promotes pliability, guarantees the PC hot bending protective film for pasting effect.
To achieve the above object, provided technical solution is the utility model: a kind of PC hot bending protective film comprising
PET protective layer, protection layer of silica gel, HC coating, PET use layer and release film layer using layer, silica gel using layer, OCA glue-line, PC,
The PET protective layer, protection layer of silica gel, HC coating, PET use layer and release film using layer, silica gel using layer, OCA glue-line, PC
Layer is successively bonded according to sequence from top to bottom.
As a kind of improvement of the utility model, the PET is using layer with a thickness of 20~100 microns.
As a kind of improvement of the utility model, the HC coating with a thickness of 2~5 microns.
As a kind of improvement of the utility model, the OCA glue-line with a thickness of 5~30 microns.
As a kind of improvement of the utility model, the PC is using layer with a thickness of 20~200 microns.
As a kind of improvement of the utility model, it is described protection layer of silica gel with a thickness of 20~60 microns.
As a kind of improvement of the utility model, the PET is using layer with a thickness of 20~60 microns.
As a kind of improvement of the utility model, the silica gel is using layer with a thickness of 20~40 microns.
As a kind of improvement of the utility model, the release film layer is fluorine element release film.
The utility model has the following beneficial effects: the utility model is reasonable in design, using PET and PC compound phase knot
Structure can reduce the stiffness of material entirety, enhance the pliability of film, and compared with traditional double-layer PET structure, whole flexibility is more
It is good, it is easier to it is hot-forming, it does not rebound, can preferably be adsorbed on the surface of 3D Curved screen；And with PET and TPU composite construction phase
Than the light transmittance of PC ratio TPU is higher, and mist degree is low, and flatness is good, can more be promoted and paste effect, and in addition overall structure is simple, light
It is thin, facilitate operation, patch viscous, is brought convenience to using, it is practical, it is conducive to wide popularization and application.
Detailed description of the invention
Fig. 1 is the cross section structure schematic diagram of the utility model.
Specific embodiment
Embodiment: referring to Fig. 1, the utility model embodiment provides a kind of PC hot bending protective film comprising PET protective layer 1,
Layer of silica gel 2, HC coating 3, PET is protected to use layer 7 and release film layer 8 using layer 6, silica gel using layer 4, OCA glue-line 5, PC, it is described
PET protective layer 1, protection layer of silica gel 2, HC coating 3, PET using layer 4, OCA glue-line 5, PC using layer 6, silica gel using layer 7 and from
Type film layer 8 is successively bonded according to sequence from top to bottom.Preferably, OCA sticker can also be passed through using the upper surface of layer 6 in PC
Conjunction has anti-blue light PET film layer (not regarding in figure), not only has anti-blue light effect, moreover it is possible to effectively promotion explosion-proof effect.
The PET using layer 4 with a thickness of 20~100 microns, preferably 35 microns.The PC using layer 6 with a thickness of
20~200 microns.Preferably 40 microns.The PET using a surface of layer 4 by the OCA glue-line 5 come with PET using layer 4 come
It matches to form composite construction, the stiffness of material entirety can be effectively reduced, enhance the pliability of film, it is easier to it is hot-forming,
It does not rebound.The OCA glue-line 5 with a thickness of 5~30 microns, preferably 15 microns.
The HC coating 3 with a thickness of 2~5 microns, preferably 3 microns.HC coating 3 uses the nanometer of model HC400
Hard paint solidification forms, and the hard coating of nanometer is coated in PET particular by dimple applicator roll and is used on another surface of layer 4,
The HC coating 3 is formed after film forming to be solidified.It is with excellent wear-resisting and Scratch Resistance energy.The hard coating of nanometer can be in city
It directly buys on face, can such as be purchased to Shanghai RaySee plastics Co., Ltd.Preferably, carrying out electricity using the upper surface of layer 4 to PET
Dizzy processing, forms corona processing layer, makes its surface tension at 56 dynes or more, and the hard coating of nanometer is coated in corona processing layer
On, it is correspondingly formed HC coating 3 after cured, can more promote HC coating 3 and PET and use the laminating effect between layer 4.
The release film layer 8 is fitted in PC using layer 7 by silica gel and uses on layer 6.The silica gel using layer 7 with a thickness of
20~60 microns, preferably 30 microns.The release film layer 8 with a thickness of 50 microns.Fluorine element release film is able to maintain protection silica gel
The surface of layer 2 is clean, avoids being stained with other sundries, and be easily peeled off, bring convenience to using, practical.
It is not scratched or is damaged by external force using preceding before use, can ensure that by PET protective layer 1 and release film layer 8,
Guarantee product quality.When stickup, release film layer 8 is removed, can preferably be adsorbed on the surface of 3D Curved screen using layer 7 by silica gel
On, and can be vented automatically, it is easy to operate.Then PET protective layer 1 is removed again.In use, due in PET using being coated on layer 4
HC coating 3, wear-resisting, anti scuffing, using effect and consistency of performance are stablized, and are mutually answered with PC using layer 6 using PET using layer 4
Conjunction forms composite construction, and compared with traditional double-layer PET structure, whole flexibility is more preferable, it is easier to and it is hot-forming, it does not rebound,
It is good that absorption pastes effect；And with PET compared with TPU composite construction, the light transmittance of PC ratio TPU is higher, and mist degree is low, and flatness is good,
