Description
Technical field
The present invention relates to the technical field of safeguard film for cellular phone, specially a kind of flexible explosion-proof diaphragm.
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 attractive in appearance and practicality of mobile phone screen, and existing flexible membrane, its table
Face is also easy to produce tiny cut, and then influences the attractive in appearance of mobile phone screen.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of flexible explosion-proof diaphragm, its surface is flexible material, while can be with
The tiny cut of self-healing, it is ensured that mobile phone screen it is attractive in appearance, and it has explosion-proof performance, it is ensured that the safety of user.
A kind of flexible explosion-proof diaphragm, it is characterised in that：Its upper protective film for including from top to bottom sequentially superimposition, H/C,
TPU, layer of silica gel, mould release membrance, the H/C are specially hardened layer/protective layer, and the TPU is TPUE.
It is further characterized by：The 2.5D arcs side position that the boundary of diaphragm after superimposition shaping corresponds to screen is
The arc side of the receipts interior from bottom to top of correspondence radian, the protection membrane structure can meet the full laminating 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, and 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 mould release membrance is specially 50 μm.
After structure using the present invention, five-layer structure is compounded to form after integral membrane, is plastic corresponding without hot pressing
Diaphragm, when there is tiny cut, H/C liquid turns to be coated onto on TPU materials, with reference to the flexibility of TPU materials, and tiny cut can be with
Automatically repair smooth, and good explosion-proof performance is generated after five-layer structure combination；To sum up, its surface is flexible material, simultaneously
Can be with the tiny cut of self-healing, it is ensured that mobile phone screen it is attractive in appearance, and it has explosion-proof performance, it is ensured that the peace of user
Entirely.
Brief description of the drawings
Fig. 1 is membrane structure simplified schematic diagram of the invention；
Fig. 2 is the main view figure structure schematic representation of the specific embodiment of the present invention；
Title in figure corresponding to sequence number is as follows：
Arc side 1.
Embodiment
A kind of flexible explosion-proof diaphragm, is shown in Fig. 1：Its upper protective film for including from top to bottom sequentially superimposition, H/C, TPU, silicon
Glue-line, mould release membrance, H/C are specially hardened layer/protective layer, and TPU is TPUE.
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, and its thickness is 100 μm~150 μm；
The thickness of layer of silica gel is specially 20 μm~25 μm；
The thickness of mould release membrance is specially 50 μm.
Specific embodiment, is shown in Fig. 2：The 2.5D arcs side position that the boundary of diaphragm after superimposition shaping corresponds to screen is
The arc side 1 of the receipts interior from bottom to top of correspondence radian, the protection membrane structure can meet the full laminating all over the screen of common 2.5D screens
Five-layer structure is compounded to form after integral membrane, is plastic corresponding diaphragm without hot pressing, when there is tiny cut
When, H/C liquid turns to be coated onto on TPU materials, and with reference to the flexibility of TPU materials, tiny cut can repair smooth automatically, and five layers
Good explosion-proof performance is generated after structure combination.
The specific embodiment of the present invention is described in detail above, but content is only the preferable implementation of the invention
Example, it is impossible to be considered as the practical range for limiting the invention.All impartial changes made according to the invention application range
Change and improvement etc., all should still be belonged within this patent covering scope.
