Layer, substrate layer, the second layer of silica gel and release film layer are successively bonded according to sequence from top to bottom, the substrate layer be PMMA, PP,
One of PE.
As a kind of improvement of the utility model, the substrate layer with a thickness of 20~100 microns.
As a kind of improvement of the utility model, first layer of silica gel with a thickness of 20~60 microns.
As a kind of improvement of the utility model, second layer of silica gel with a thickness of 20~60 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 HC coating with a thickness of 2~5 microns.HC coating is that nanometer applies firmly
Layer.
As a kind of improvement of the utility model, the release film layer is fluorine element release film.Fluorine element release film is able to maintain
The surface of second silica gel layer is clean, avoids being stained with other sundries, and be easily peeled off, bring convenience to using, practical.
As a kind of improvement of the utility model, the PET is using layer with a thickness of 20~100 microns.
The utility model has the following beneficial effects: the utility model is reasonable in design, using composite construction, PET is made
It is mutually compound with layer and the substrate layer of other materials such as PMMA, PP, PE, the stiffness of material entirety can be reduced, the softness of film is enhanced
Degree, it is easier to it is hot-forming, it does not rebound, can preferably be adsorbed on the surface of 3D Curved screen；In addition overall structure is simple, frivolous,
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 3D hot bending protective film comprising PET protective layer 1,
First layer of silica gel 2, HC coating 3, PET use layer 4, OCA glue-line 5, substrate layer 6, the second layer of silica gel 7 and release film layer 8, described
PET protective layer 1, the first layer of silica gel 2, HC coating 3, PET use layer 4, OCA glue-line 5, substrate layer 6, the second layer of silica gel 7 and release
Film layer 8 is successively bonded according to sequence from top to bottom, and the substrate layer 6 is one of PMMA, PP, PE.The substrate layer 6
With a thickness of 20~100 microns, preferably 30 microns.It adopts and uses it to carry out Xiang Fuhe using layer 4 with PET, material entirety can be reduced
Stiffness, enhance the pliability of film, it is easier to it is hot-forming, do not rebound.Preferably, the upper surface of layer 4 can also be used in PET
There is anti-blue light PET film layer (not regarding in figure) by OCA glue laminating, not only there is anti-blue light effect, moreover it is possible to effectively promote explosion-proof effect
Fruit.
First layer of silica gel 2 with a thickness of 20~60 microns, preferably 40 microns.The thickness of second layer of silica gel 7
It is 20~60 microns, preferably 40 microns.The OCA glue-line 5 with a thickness of 5~30 microns, preferably 10 microns.The PET
Using layer 4 with a thickness of 20~100 microns, preferably 50 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 layer 4, film forming to be solidified
The HC coating 3 is formed afterwards.It is with excellent wear-resisting and Scratch Resistance energy.The hard coating of nanometer can be purchased directly in the market
, it can such as be purchased to Shanghai RaySee plastics Co., Ltd.Preferably, carrying out sided corona treatment, shape using the upper surface of layer 4 to PET
At corona processing layer, make its surface tension at 56 dynes or more, the hard coating of nanometer is coated in corona processing layer, after cured
It is correspondingly formed HC coating 3, HC coating 3 and PET can be more promoted and use the laminating effect between layer 4.
