Description
Technical field
The utility model relates to mobile phone waterproof membranes, more specifically to a kind of mobile phone breathable waterproof membrane.
Background technique
With the continuous development of electronics techniques, smart phone, laptop, intercom, bluetooth headset, outdoor prison
It is more more and more universal to control the electronic equipments such as device, electronics is set in order to reduce aquatic sports, outdoor environment and daily life with when water
It is damaged caused by standby, usually assembles waterproof sound passing membrane in the loudspeaker of electronic equipment, microphone or headphone.
Currently, general waterproof sound passing membrane can satisfy the waterproofing grade requirement of IPX7, but be not able to satisfy IPX5 or
The requirement of IPX6 waterproofing grade.Because water is directly flushed on waterproof sound passing membrane when being IPX5 or IPX6 and testing, film will be layered or
Water, which can enter cavity through film, leads to test crash.Therefore, how can make the waterproofing grade of waterproof sound passing membrane reach IPX5,
IPX6, IPX7 waterproofing grade, but can reduce to the influence of sound translative performance is those skilled in the art's technical problem urgently to be resolved.
Utility model content
In view of the above defects of the prior art, the purpose of the utility model is to provide a kind of mobile phone air permeable waterproofs
Film, to solve problems of the prior art.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of mobile phone breathable waterproof membrane, comprising: by upper protective layer, waterproof layer and the supporting layer being sequentially connected under；
The protective layer is release paper, is bonded by viscose glue and waterproof layer；
The waterproof layer is PTFE film, and porosity >=80% of PTFE film contains conductive material in PTFE film；
Also contain conductive material in the supporting layer；
The waterproof membrane whole installation is rounded or rectangle.
The viscose glue is acrylic acid.
The waterproofing layer thickness is 0.5~2um.
The supporting layer is PET, polyester or non-woven fabrics, with a thickness of 0.1~0.2mm.
The conductive material is carbon black conductive material or conductive polymer material.
On the other hand, a kind of mobile phone breathable waterproof membrane preparation process, comprising: by the PET, polyester or non-woven fabrics raw material
In be mixed into the carbon black conductive material or conductive polymer material, the charcoal unlicensed tour guide is also mixed into the PTFE raw material
Electric material or conductive polymer material, be supported layer and waterproof layer；
The mixed volume of the conductive polymer material is 1%~5%.
The conductive polymer material is poly- thiophene sulfone class.
In the above technical solution, a kind of mobile phone breathable waterproof membrane provided by the utility model, can directly paste in
In on mobile phone component, there is good dust-proof effect, dust-proof efficiency can reach 99.5% or more, and waterproof efficiency can reach 3 meters
Water pressure resistance, and 24 hours are water-tight, have good gas permeability, to keep internal and external pressure balance, equalized temperature, and guarantee sound
Sound transmission is undistorted.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model mobile phone breathable waterproof membrane；
Fig. 2 is a kind of schematic diagram of embodiment of the utility model mobile phone breathable waterproof membrane；
Fig. 3 is the schematic diagram of another embodiment of the utility model mobile phone breathable waterproof membrane.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1 to Fig. 3, a kind of mobile phone breathable waterproof membrane provided by the utility model, comprising: by upper under
Protective layer 1, waterproof layer 2 and the supporting layer 3 being sequentially connected, protective layer 1 is covered on the upper surface of waterproof layer 2, to protect waterproof
Layer 2 is being not used by the defects of front surface is scratched or pokes, since waterproof layer 2 is than relatively thin, also need by supporting layer 3 to its into
Row Auxiliary support.
Preferably, the protective layer 1 is release paper, bonded by viscose glue 4 and waterproof layer 2, viscose glue 4 selects acrylic acid material
Matter, before use, protective layer 1 is bonded by viscose glue 4 with waterproof layer 2, and in use, first opening protective layer 1, due to protective layer 1
Using release paper, therefore, viscose glue 4 is all attached to the surface of 2 periphery of waterproof layer, and waterproof layer 2 can be covered on electronic component, prevents
The periphery of water layer 2 passes through viscose glue 4 again and is fitted in around electronic component.And on the another side of waterproof layer 2, supporting layer can be passed through
3 carry out reinforcing support, prevent waterproof layer 2 from falling off on electronic component.
Preferably, the PTFE film that the waterproof layer 2 is selected with a thickness of 0.5~2um, porosity >=80% of PTFE film,
Conductive material is mixed into PTFE film.
Preferably, being also mixed into conductive material in the supporting layer 3.Conductive material master is mixed into waterproof layer 2, supporting layer 3
If avoiding damage electronic component to play anti-static electrification.
Preferably, the supporting layer 2 selects PET, polyester or non-woven fabrics, with a thickness of 0.1~0.2mm.
Preferably, the waterproof membrane whole installation is rounded or rectangle, shape setting can be carried out according to actual needs,
It is not limited to round or rectangle.
Preferably, the conductive material is carbon black conductive material or conductive polymer material, electric conductivity is preferable, is also easy to
It is mixed into.
The preparation process of a kind of mobile phone breathable waterproof membrane provided by the utility model, comprising: by the PET, polyester
Or the carbon black conductive material or conductive polymer material are mixed into non-woven fabrics raw material, the layer that is supported is made, described
Also it is mixed into the carbon black conductive material or conductive polymer material in PTFE raw material, is made to obtain waterproof layer.
Preferably, the mixed volume of the conductive polymer material is 1%~5%.
Preferably, the conductive polymer material is poly- thiophene sulfone class.
In addition, the utility model additionally provides another mobile phone breathable waterproof membrane preparation process, comprising: by supporting layer and prevent
After water layer carries out composite molding using hot composition process, spraying conductive material process is carried out on the surface of supporting layer and waterproof layer.
Preferably, the conductive material is conductive polymer solution or conductive ink.
In conclusion the utility model can be directly adhered on mobile phone component, there is good dust-proof effect, dust-proof effect
Rate can reach 99.5% or more, and waterproof efficiency can reach 3 meters of water pressure resistances, and 24 hours are water-tight, have good gas permeability, from
And internal and external pressure balance, equalized temperature are kept, and guarantee that voice transmission is undistorted.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
