Description

Technical Field

[0001] The utility model relates to the technical field of silica gel protective films, in particular to a low-temperature curing silica gel protective film. Background Technique

[0002] The silica gel protection film is a screen protection film mainly used to protect electronic products. The current mainstream silica gel protection film is the PET silica gel screen protection film, and the silica gel protection film can be divided into: digital product silica gel protection film, automotive silica gel protection film, household silica gel protection film, etc.

[0003] When the existing silica gel protection film protects the screen of an electronic product, during long-term use, it is easily affected by external impacts, making the protection film become more and more loose, especially at the edges of the protection film. Currently, the main method is to increase the adhesion effect at the edges, but the method is relatively single, and the adhesion effect of the adhesive is also prone to slow dilution. The overall fastening stability is still poor, which also reduces the overall durability of the protection film. Moreover, the edges of the protection film are generally impacted most frequently, and the single-frame protection has a low effect, affecting the overall use effect of the protection film.

[0004] Therefore, we propose a low-temperature curing silica gel protection film to solve the above problems. Content of the Utility Model

[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0030] The following describes a low-temperature curing silicone protective film provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] Combined with Figures 1-3 As shown, a low-temperature curing silicone protective film provided by the present utility model

[0033] Specifically, it includes a main film body 1 and a protective frame 2 sleeved on the outer four edges of the main film body 1. The main film body 1 includes an upper transparent protective layer 101, two groups of base material layers 102, an inner filling capsule layer 103, a film sticking layer 104 and two groups of adhesive layers 105. Installation through holes 6 are provided on the inner side of the protective frame 2. The installation through holes 6 are mainly for facilitating the installation of the compression air bags 3, and at the same time for facilitating the clamping of both sides of the two groups of adhesive layers 105 and the inner filling capsule layer 103. A plurality of groups of compression air bags 3 are symmetrically arranged up and down inside the installation through holes 6. Communication rubber tubes 5 are installed through the bonding parts of the two groups of adhesive layers 105 and the inner filling capsule layer 103 and the abutting parts of one ends of the plurality of groups of compression air bags 3. The other ends of the plurality of groups of compression air bags 3 are all connected with elastic pressing sheets 4. The outer sides of the film sticking layer 104 at the bottom are located at the bottom of the protective frame 2 and are all connected with adsorption gaskets 7. A sealing rubber layer 8 is embedded and clamped inside the bottom of the adsorption gasket 7. The bonding effect of the sealing rubber layer 8 is stronger than that of the film sticking layer 104 and has a certain sealing property to prevent gas from infiltrating. The two groups of adhesive layers 105 are bonded to the upper and lower ends of the inner filling capsule layer 103. The four sides of the two groups of adhesive layers 105 and the inner filling capsule layer 103 are all embedded inside the protective frame 2. The two groups of base material layers 102 are bonded to the outer sides of the two groups of adhesive layers 105 and are attached and connected to the upper and lower inner side surfaces of the protective frame 2. The upper transparent protective layer 101 is bonded to one side of the two groups of base material layers 102 and the top surface of the protective frame 2. The film sticking layer 104 is bonded to the other side of the two groups of base material layers 102. One ends of the elastic pressing sheets 4 are respectively connected through the upper and lower end surfaces of the protective frame 2 and are respectively connected to the upper transparent protective layer 101 and the adsorption gasket 7. The inner filling capsule layer 103 is interconnected with the plurality of groups of compression air bags 3 through the communication rubber tubes 5. When the above-mentioned components are used, an external force causes the elastic pressing sheets 4 to forcefully squeeze the compression air bags 3, and the gas is injected into the inner filling capsule layer 103 through the communication rubber tubes 5, making it expand and squeeze the base material layer 102 and the film sticking layer 104, enhancing the squeezing tightness with the bonded object, preventing loosening, and improving the use stability and durability of the protection film.

[0034] Embodiment Two:

[0035] As shown in the figure and based on Embodiment One,

[0036] Specifically, a trapezoidal adsorption rubber tube 9 is installed through the middle of the connection part between the bottom end of the adsorption gasket 7 and the sealing rubber layer 8. The trapezoidal adsorption rubber tube 9 is designed with a smaller upper part and a larger lower part, which can enhance the adsorption property of the adsorption gasket 7. When the above-mentioned components and the components in Embodiment One are used, especially the elastic effect of the elastic pressing sheet 4 and the compression air bag 3, the adsorption gasket 7 outside the film sticking layer 104 is more stable in bonding to the bonded object through the adsorption effect of the trapezoidal adsorption rubber tube 9 and the bonding of the sealing rubber layer 8, improving the protection effect of the protective frame and also improving the use effect.

[0037] Working principle and usage process of the present utility model: First, during use, after the protective film is integrally pasted to the protected object, the bottom of the film layer 104 is made to fit the surface of the object. When impacted by an external force or when the user squeezes the protective film during use, the force causes the elastic pressing piece 4 to squeeze the compression airbag 3, and the gas is continuously injected into the inner filling capsule layer 103 through the connecting rubber tube 5. It continuously expands and squeezes the base material layer 102 and the film layer 104, enhancing the squeezing fastness with the adhered object, preventing loosening, and improving the use stability and durability of the protective film. Secondly, during use, in the use of the above-mentioned various components, especially the elastic action of the elastic pressing piece 4 and the compression airbag 3, the adsorption gasket 7 outside the film layer 104 is more stable in adhering to the adhered object through the adsorption action of the trapezoidal adsorption rubber tube 9 and the adhesive layer 8, slowing down the vibration force, improving the protection effect of the protective frame, and also improving the use effect of the protective film.

[0038] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
