Feature.
Description of the drawings
Fig. 1 is the process flow chart of the application.
Fig. 2 is the final finished structural schematic diagram of the application.
In figure label for：Electrostatic film 1, glue-line 2.
Specific implementation mode
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the production method of Curved screen safeguard film for cellular phone, includes the electrostatic film 1 as base material, the light transmission of PET
Rate is good, hardness is moderate, and electrostatic film 1, to achieve the purpose that fitting, is carried compared to using by Electrostatic Absorption mobile phone screen protection
The PET of glue surface, the fitting mobile phone heel row bubble performance of electrostatic film 1 is more preferable, and it is 0.1mm to 1.0mm to make the thickness of the electrostatic film 1, also
Include the following steps：
E, it is sliced, is specifically, slicing treatment is carried out to 1 base material of electrostatic film, electrostatic film 1 is cut to film of the same size
Piece, the diaphragm size are suitable in the hot press of subsequent technique,
F, hot pressing is specifically to carry out hot-pressing processing to the electrostatic film 1 being sliced, the mold used in hot pressing is Curved screen
It is adapted to mold, the hot pressing temperature is 80 DEG C to 90 DEG C, and the electrostatic film 1 being sliced is placed on hot press, and control mold carries out
Hot pressing, since in the application, base material is electrostatic film 1, therefore is not in that glue surface is destroyed by high temperature in hot pressing
The case where, another aspect base material thickness controls between 0.1mm and 0.8mm, when thickness is less than 0.1mm, excessively thin electrostatic film 1 warp
It crosses high temperature and is easy to happen fold, when thickness is more than 0.8mm, the translucency of electrostatic film 1 is poor, and cost is higher,
G, profiling is die cut, and is specifically, and the shape that the good electrostatic film 1 of hot pressing is had more to the Curved screen being adapted to carries out profile mould
