Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silica gel films, in particular to an impact-resistant silica gel film. Background Technique
[0002] The impact-resistant silica gel film is a material with excellent elasticity and impact resistance. It is usually made of silicone rubber. Silicone rubber has good elasticity and can absorb and disperse the impact force when being impacted. The impact-resistant silica gel film can maintain stable performance within a wide temperature range and can be used from extremely low temperatures to relatively high temperatures. It has good resistance to environmental factors such as ultraviolet rays, ozone, and oxygen and is suitable for outdoor use. Therefore, the impact-resistant silica gel film is widely used in various fields. It includes the mobile phone field. A layer of impact-resistant silica gel film can be attached to the mobile phone screen to protect the mobile phone screen from damage caused by dropping and impact.
[0003] Currently, when most users apply the film, they will purchase the silica gel film by themselves and apply the film by themselves. When users apply the film by themselves, they do not have the professional working equipment and environment in the mobile phone store. Therefore, the silica gel film manufacturer needs to simplify the design of the silica gel film to simplify the difficulty of applying the film. When applying the film, first, the mobile phone screen needs to be wiped to remove the oil and dust on the mobile phone to prevent dust from existing between the silica gel film and the mobile phone screen, which may cause bubbles in the silica gel film and thus reduce the film application effect. After wiping, after removing the bottom release film, the middle impact-resistant film is attached to the screen. However, when the screen is wiped, especially when using a dry cloth or tissue paper, static electricity will be generated. Static electricity will attract dust particles in the air because dust usually carries tiny charges, and these charges are attracted to the static electricity on the screen, resulting in the dust being adsorbed on the screen. The surface energy of the cleaned screen is relatively high, that is, the intermolecular interaction force on the surface is relatively strong, which makes the screen surface more likely to adsorb surrounding particles, including dust. As a result, the just-cleaned screen will be re-attached with dust during the process of removing the bottom release film, and when applying the film, it is generally pushed from one side to the other gradually. During the pushing process, dust may still fall on the mobile phone screen, thus reducing the visual effect after applying the film. Content of the Utility Model
[0004] The purpose of the utility model is to address the problems in the background technique and propose an impact-resistant silica gel film that can use the bottom release film separated from the middle impact-resistant film to adsorb dust on the screen.
[0005] The technical solution of the utility model: An impact-resistant silica gel film, including a middle impact-resistant film, a top protective film pasted on one side of the middle impact-resistant film, and a bottom release film pasted on the other side of the middle impact-resistant film, characterized in that it further includes:
[0006] An antistatic agent coating applied to the side of the bottom release film close to the middle impact-resistant film;
[0007] A fitting guiding mechanism connected to the bottom release film. The fitting guiding mechanism controls the bottom release film after detaching from the middle impact-resistant film to fit and move along the screen, and makes the antistatic agent coating face the side close to the screen.
[0008] Optionally, the fitting guiding mechanism includes a flexible sheet installed on the bottom release film. Sliders are fixedly connected to both sides of the flexible sheet. A slide bar is slidably installed on the two sliders. The slide bar penetrates through the two sliders. Tightening heads are threadedly connected to both sides of the slide bar. A connecting block is rotatably installed in the middle of the slide bar. A pull rope is fixedly installed on the connecting block.
[0009] Optionally, a flexible sliding sheet is fixedly installed on the slider, and a lubricant is coated on the flexible sliding sheet.
[0010] Optionally, the flexible sheet is U-shaped, and the bottom release film and the slider are located at both ends of the flexible sheet.
[0011] Optionally, two positioning stickers are installed on the top protective film, and the positioning stickers fix the position of the top protective film.
[0012] Optionally, the positioning sticker includes a positioning piece fixedly connected to the top protective film. An adhesive layer is coated on the positioning piece, and a release sheet is adhered to the adhesive layer.
[0013] Optionally, an adhesive is coated on one side of the middle impact-resistant film, and the adhesive is located on the side of the middle impact-resistant film close to the bottom release film.
[0014] Optionally, the middle impact-resistant film includes a silicone rubber base material, impact-resistant fillers, and a crosslinking agent.
[0015] In summary, the present application includes at least one of the following beneficial technical effects:
[0016] By coating an antistatic agent coating on the side of the bottom release film close to the middle impact-resistant film, after the bottom release film detaches from the middle impact-resistant film, the antistatic agent coating on the detached bottom release film will be exposed to the air and face the direction of the mobile phone screen, which can attract and capture charged dust particles in the air. Furthermore, it can make the bottom release film adsorb the dust on the mobile phone screen, and can further remove the dust on the mobile phone screen before the middle impact-resistant film is attached to the mobile phone screen, effectively improving the effect after the mobile phone screen is pasted with a film.
[0017] Further, by slidably connecting two sliders to the side of the mobile phone, pulling the pull rope can drive the sliders to slide along the mobile phone screen, and then drive the bottom release film to move, so that the bottom release film can be detached from the middle shock-resistant film. By guiding the bottom release film with the sliders, the bottom release film can always move along close to the mobile phone screen, and thus the electrostatic agent coating can effectively remove dust from the mobile phone screen.

SPECIFIC EMBODIMENTS
[0025] The technical solutions of the present utility model will be further described below with reference to the drawings and specific embodiments.
[0026] Embodiment
[0027] As Figures 1-6As shown in the figure, a silicone film with impact resistance proposed by the present utility model includes a middle impact-resistant film 1, a top protective film 2 pasted on one side of the middle impact-resistant film 1, and a bottom release film 3 pasted on the other side of the middle impact-resistant film 1. It further includes an electrostatic agent coating 4 coated on the side of the bottom release film 3 close to the middle impact-resistant film 1. When applying the film, first, one side of the bottom release film 3 is detached from the middle impact-resistant film 1, and then a squeegee 7 is used to apply pressure and thrust to the top protective film 2 from this side. At this time, the bottom release film 3 can be continuously detached from the middle impact-resistant film 1, and the electrostatic agent coating 4 on the detached bottom release film 3 will be exposed to the air and face the direction of the mobile phone screen 8. Coating the electrostatic agent on the bottom release film 3 can make the film adsorb dust. After coating the electrostatic agent, static charges will be generated on the surface of the bottom release film 3, and these static charges can attract and capture charged dust particles in the air. Furthermore, it can make the bottom release film 3 adsorb the dust on the mobile phone screen 8, and can perform further dust removal treatment on the mobile phone screen 8 before the middle impact-resistant film 1 is attached to the mobile phone screen 8, effectively improving the effect after the mobile phone screen 8 is pasted with the film.
[0028] A fitting guiding mechanism connected to the bottom release film 3 controls the bottom release film 3 that has detached from the middle impact-resistant film 1 to move while fitting to the screen, and makes the electrostatic agent coating 4 face the side close to the screen. The fitting guiding mechanism includes a flexible sheet 506 installed on the bottom release film 3. Sliders 5 are fixedly connected to both sides of the flexible sheet 506. A sliding rod 501 is slidably installed on the two sliders 5. The sliding rod 501 passes through the two sliders 5. Fastening heads 502 are threadedly connected to both sides of the sliding rod 501. A connecting block 503 is rotatably installed in the middle of the sliding rod 501, and a pulling rope 504 is fixedly installed on the connecting block 503. When applying the film, first, the two sliders 5 are placed on both sides of the mobile phone screen 8 and close to the end where the film application starts first, and then the fastening heads 502 are rotated to make the sliders 5 abut against the mobile phone screen 8. At this time, pulling the pulling rope 504 can drive the sliding rod 501 to move, and then drive the two sliders 5 to slide along the mobile phone screen 8, and then drive the bottom release film 3 to move. The bottom release film 3 can be detached from the middle impact-resistant film 1, and at the same time, the squeegee 7 is used to apply pressure and thrust to the top protective film 2 so that the middle impact-resistant film 1 adheres to the mobile phone screen 8 at the speed of the bottom release film 3 detaching from the middle impact-resistant film 1. And the bottom release film 3 is guided by the sliders 5, so that the bottom release film 3 can always move along the direction close to the mobile phone screen, and thus the electrostatic agent coating 4 can effectively remove dust from the mobile phone screen 8.
[0029] Further, a flexible sliding piece 505 is fixedly installed on the slider 5, and a lubricant is coated on the flexible sliding piece 505. The flexible deformation of the flexible sliding piece 505 can prevent the flexible sliding piece 505 from scratching the side of the mobile phone. The lubricant can reduce the friction between the flexible sliding piece 505 and the side of the mobile phone, further preventing the flexible sliding piece 505 from scratching the side of the mobile phone.
[0030] Among them, the flexible sheet 506 is U-shaped, and the bottom release film 3 and the slider 5 are located at both ends of the flexible sheet 506. Through the U-shaped setting of the flexible sheet 506, the bottom release film 3 can be more conveniently detached from the middle shock-resistant film 1.
[0031] Two positioning stickers are installed on the top protective film 2, and the positioning stickers fix the position of the top protective film 2. The positioning sticker includes a positioning piece 6 fixedly connected to the top protective film 2. An adhesive layer 601 is coated on the positioning piece 6, and a release piece 602 is adhered to the adhesive layer 601. Tear off the release piece 602 and stick the positioning piece 6 on the side of the mobile phone to position the top protective film 2, thereby positioning the middle shock-resistant film 1, which can prevent the middle shock-resistant film 1 from skewing during the film application. When the bottom release film 3 is completely detached from the middle shock-resistant film 1, that is, when the middle shock-resistant film 1 is completely attached to the mobile phone screen 8, the top protective film 2 can be detached from the middle shock-resistant film 1 by pulling the positioning piece 6. The top protective film 2 prevents the scraper 7 from scratching the middle shock-resistant film 1.
[0032] An adhesive is coated on one side of the middle shock-resistant film 1, and the adhesive is located on the side of the middle shock-resistant film 1 close to the bottom release film 3. Through the adhesive, the middle shock-resistant film 1 can be pasted on the mobile phone screen 8. The middle shock-resistant film 1 includes a silicone rubber base material, an impact-resistant filler, and a cross-linking agent. The silicone rubber base material is the main component of the silicone film and is usually composed of polysiloxane polymers. Silicone rubber has excellent heat resistance, cold resistance, electrical insulation, and chemical stability. The filler is used to improve the mechanical properties and impact resistance of the silicone film, and fillers are usually added. Commonly used fillers include fumed silica, diatomaceous earth, quartz powder, etc. The filler can enhance the strength and wear resistance of the silicone. The cross-linking agent is used to form chemical bonds between the silicone rubber molecular chains, thereby improving the physical and chemical properties of the silicone film. Common cross-linking agents include organic peroxides, silicon hydrides, etc.
[0033] Working principle: When applying the film, first place the two sliders 5 on both sides of the mobile phone screen 8 and close to one end where the film is first applied. Then rotate the fastening head 502 to make the slider 5 abut against the mobile phone screen 8. At this time, pulling the pull rope 504 can drive the slide bar 501 to move, thereby driving the two sliders 5 to slide along the mobile phone screen 8, and then driving the bottom release film 3 to move. This can make the bottom release film 3 separate from the middle impact-resistant film 1. At the same time, use the squeegee 7 to apply pressure and thrust to the top protective film 2, so that the middle impact-resistant film 1 adheres to the mobile phone screen 8 at the speed of the separation of the bottom release film 3 from the middle impact-resistant film 1. And through the sliders 5 to guide the bottom release film 3, so that the bottom release film 3 can always move along close to the mobile phone screen, and then the electrostatic agent coating 4 can effectively remove dust from the mobile phone screen 8.
[0034] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
