Abstract
The utility model provides a kind of flexible explosion-proof protective film, its surface is flexible material, while can ensure that the beauty of mobile phone screen, and it ensure that the safety of user with explosion-proof performance with the tiny cut of self-healing.It includes from top to bottom the upper protective film of sequentially superimposition, H/C, TPU, layer of silica gel, release film, and the H/C is specially hardened layer/protective layer, and the TPU is thermoplastic polyurethane elastomer.
Description
Technical field
The technical field of safeguard film for cellular phone is the utility model is related to, is specially a kind of flexible explosion-proof protective film.
Background technology
The structure of existing safeguard film for cellular phone, otherwise be partially hard tempering film, or be easily by the flexible membrane of surface tear,
Its in use, tempering film is too hard and thick, does not utilize the beautiful and practical of mobile phone screen, and existing flexible membrane, its table
Face is also easy to produce tiny cut, and then influences the beauty of mobile phone screen.
The content of the invention
In view of the above-mentioned problems, the utility model provides a kind of flexible explosion-proof protective film, its surface is flexible material, at the same time
The beauty of mobile phone screen can be ensure that, and it ensure that the peace of user with explosion-proof performance with the tiny cut of self-healing
Entirely.
A kind of flexible explosion-proof protective film, it is characterised in that：It include from top to bottom the upper protective film of sequentially superimposition, H/C,
TPU, layer of silica gel, release film, the H/C are specially hardened layer/protective layer, and the TPU is thermoplastic polyurethane elastomer.
It is further characterized by：The 2.5D arcs side position that the boundary of protective film after superimposition shaping corresponds to screen is
The arc side of the receipts interior from bottom to top of corresponding radian, the protection membrane structure can meet the full fitting all over the screen of common 2.5D screens；
The thickness of the upper protective film is 5 μm；
The H/C thickness is 2 μm~3 μm；
The TPU has remarkable high-tension, high-tensile strength, obdurability and anti-aging characteristic, its thickness is 100 μm~150 μ
m；
The thickness of the layer of silica gel is specially 20 μm~25 μm；
The thickness of the release film is specially 50 μm.
After the structure of the utility model, after five-layer structure is compounded to form integral membrane, without hot pressing, that is, plastic right
The protective film answered, when there is tiny cut, H/C liquid turns to be coated onto on TPU materials, with reference to the flexibility of TPU materials, tiny cut
Can repair automatically it is smooth, and five-layer structure combination after generate good explosion-proof performance；To sum up, its surface is flexible material,
The beauty of mobile phone screen can be ensure that, and it ensure that user's with explosion-proof performance with the tiny cut of self-healing at the same time
Safety.
Brief description of the drawings
Fig. 1 is the membrane structure simplified schematic diagram of the utility model；
Fig. 2 is the main view schematic diagram of specific embodiment of the utility model；
Title in figure corresponding to sequence number is as follows：
Arc side 1.
Embodiment
A kind of flexible explosion-proof protective film, is shown in Fig. 1：It includes from top to bottom the upper protective film of sequentially superimposition, H/C, TPU, silicon
Glue-line, release film, H/C are specially hardened layer/protective layer, and TPU is thermoplastic polyurethane elastomer.
The thickness of upper protective film is 5 μm；
H/C thickness is 2 μm~3 μm；
TPU has remarkable high-tension, high-tensile strength, obdurability and anti-aging characteristic, its thickness is 100 μm~150 μm；
The thickness of layer of silica gel is specially 20 μm~25 μm；
The thickness of release film is specially 50 μm.
Specific embodiment, is shown in Fig. 2：The 2.5D arcs side position that the boundary of protective film after superimposition shaping corresponds to screen is
The arc side 1 of the receipts interior from bottom to top of corresponding radian, the protection membrane structure can meet the full fitting all over the screen of common 2.5D screens
After five-layer structure is compounded to form integral membrane, without hot pressing, that is, plastic corresponding protective film, when there is tiny cut
When, H/C liquid turns to be coated onto on TPU materials, with reference to the flexibility of TPU materials, tiny cut can repair automatically it is smooth, and five layers
Good explosion-proof performance is generated after structure combination.
Specific embodiment of the utility model is described in detail above, but content is only what the utility model was created
Preferred embodiment, it is impossible to be construed as limiting the practical range of the utility model creation.All created according to the utility model is applied
All the changes and improvements that scope is made etc., should all still belong within this patent covering scope.
