Example Embodiment
[0050] Example 1
[0051] Such as figure 1 The mobile phone protective film shown is directly connected between two adjacent layers. The size and shape of the mobile phone protective film are determined according to the mobile phone model and screen size. The thickness of the first release layer is 30 μm, the thickness of the overheat protection layer is 20 μm, the thickness of the temperature-sensitive coating layer is 2 μm, the thickness of the transparent substrate layer is 50 μm, and the thickness of the second release layer is 30 μm.
[0052] When sticking the film on the mobile phone screen, first wipe the screen clean to remove the oil or moisture on the surface, and then peel off the first release layer, such as figure 2 As shown, start pasting from one corner of the mobile phone, use a thin plate or the like to slowly compact the protective film, expel the air bubbles, and finally peel off the upper second release layer from the second adhesive layer to complete the pasti...
Example Embodiment
[0054] Example 2
[0055] The shape of the mobile phone protective film is the same as in Example 1. The thickness of the first release layer is 10 μm, the thickness of the temperature-sensitive coating layer is 10 μm, the thickness of the overheat protection layer is 50 μm, the thickness of the transparent substrate layer is 20 μm, and the thickness of the second release layer is 60 μm.
[0056] The mobile phone filming method is the same as in Example 1.
[0057] The experimental method is the same as in Example 1. After running for 6 hours, the average temperature of the mobile phone in the experimental group is 44℃, the average temperature of the control group is 51℃, and the average temperature of the blank group is 50℃. The test shows that the mobile phone protective film of the present invention can be effective Absorb the heat generated during the operation of the mobile phone.
Example Embodiment
[0058] Example 3
[0059] The shape of the mobile phone protective film is the same as in Example 1. The thickness of the first release layer is 80 μm, the thickness of the temperature-sensitive coating layer is 30 μm, the thickness of the overheat protection layer is 10 μm, the thickness of the transparent substrate layer is 200 μm, and the thickness of the second release layer is 20 μm.
[0060] The mobile phone filming method is the same as in Example 1.
[0061] Set the refrigerator temperature to 0°C. After 1h of stability, place the mobile phone in the refrigerator to detect the temperature of the mobile phone core in real time. After 3h, take it out. The average temperature of the mobile phone in the experimental group is 20°C, and the average temperature of the mobile phone in the control group is 10°C. The average temperature of the group of mobile phones is 10°C, and experiments show that the mobile phone protective film of the present invention can effectively absorb the...
