Example Embodiment
[0014] Example 1
[0015] (1) Place the PET material in a stamping machine for stamping and forming to obtain an unprinted PET layer;
[0016] (2) Print a layer on one surface of the unprinted PET layer to obtain a printed PET layer;
[0017] (3) Put the printed PET layer in a dryer for baking, where the baking temperature is 80°C and the baking time is 60 minutes;
[0018] (4) Put the printed PET layer of the baking shield in the forming production mold, and then apply the liquid silicone on the printed PET layer, and connect the printed PET layer and the liquid silicone by thermocompression molding to obtain a composite type Protective film, among which, the temperature of hot pressing is 120℃ and the pressure is 80kg / cm 2 , The time is 80 seconds;
[0019] (5) Cool the composite protective film at room temperature to obtain the finished composite PET protective film.
