Problems solved by technology

However, it mainly relies on axial flow fans to blow heat, and also requires batteries, temperature sensors and other equipment, and the preparation process is complicated.
Patent CN202908053U discloses a method for cooling electronic products using a cooling bag made of phase-change cooling material or metal material. It mainly uses the heat of dissolution of inorganic substances or metal cooling. The main problems are: 1) the dissolution process of inorganic substances 2) The use of metal materials for cooling will increase the weight of mobile phones, which is contrary to the development trend of light and thin mobile phones
[0006] The impact of high temperature on mobile phones is obvious, and it will also attract people's attention, but the damage caused by low temperature to mobile phones cannot be ignored. For example, in some northern areas, the outdoor temperature will drop to -20 to -30°C in winter. When the temperature is too low, mobile phones Will run slower, use more power, and have poorer battery performance
However, the method of heating the mobile phone has not been reported yet.

Embodiment 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 paint 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 a film on the screen of a mobile phone, first wipe the screen clean to remove oil or moisture on the surface, and then remove the first release layer, such as figure 2 As shown, paste from the corner of the mobile phone, slowly compact the protective film with a thin plate, etc. to expel air bubbles, and finally peel off the second release layer on the upper layer from the second adhesive layer, and the film is completed.

[0053] The mob...

Embodiment 2

[0055] The shape of the mobile phone protective film is the same as that of Embodiment 1. The thickness of the first release layer is 10 μm, the thickness of the temperature-sensitive paint 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 film sticking 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 phones in the experimental group is 44°C, the average temperature of the mobile phones in the control group is 51°C, and the average temperature of the blank group is 50°C. The test shows that the mobile phone protective film of the present invention can effectively Absorb the heat generated during the operation of the mobile phone.

Embodiment 3

[0059] The shape of the protective film of the mobile phone is the same as in Example 1. The thickness of the first release layer is 80 μm, the thickness of the temperature-sensitive paint 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 film sticking method is the same as in Example 1.

[0061] Set the temperature of the refrigerator to 0°C. After 1 hour of stabilization, place the mobile phone in the refrigerator, detect the temperature of the core of the mobile phone in real time, and take it out after 3 hours. The average temperature of the assembled mobile phone is 10°C. The test shows that the mobile phone protective film of the present invention can effectively absorb the heat generated during the operation of the mobile phone. It shows that the mobile phone protective film of the present invention can rel...

Abstract

The invention relates to a mobile phone protection film with overheat / overcold protection and warning functions. The mobile phone protection film comprises a first release layer, a first adhesive layer, a transparent substrate layer, an overheat / overcold protection layer and a temperature-sensitive dope layer which are arranged in sequence, wherein two adjacent layers directly contact with each other. According to the invention, when the temperature of a mobile phone is too high or too low, the overheat / overcold protection layer may undergo solid-solid phase change so as to absorb or release heat accordingly, so the temperature of the mobile phone is prevented from too high or too low; and the temperature-sensitive dope layer can present different colors in a certain temperature range so as to warn a user of the mobile phone, and thus, a better protection effect is exerted on the mobile phone.

Description

technical field [0001] The invention relates to a mobile phone protective film, in particular to a mobile phone protective film capable of providing overheat / overcool protection and warning functions. Background technique [0002] For more and more smart phones, touch screen has become a very common operation mode. For this type of product, the tactility and protection of the touch screen are the parts that users are very concerned about. As far as the mobile phone itself is concerned, the touch of the screen can already realize single-point touch very well, and the sensitivity is high, but the protection of the screen has not yet reached a perfect state, and it will still be damaged in daily use. In this case, most users will buy a mobile phone protective film to further protect the mobile phone. [0003] The protective films for mobile phones on the market are classified according to their functions, mainly including high-transparency films, frosted films, anti-peeping f...
