Description

Technical Field

[0001] The utility model relates to the technical field of screen protective films, in particular to a screen protective film which can improve the connection stability with the screen of an electronic device, is reusable, and can effectively attenuate electromagnetic radiation. Background Art

[0002] Screen protector, also known as screen beauty film, is a cold-mounted film used to be mounted on the surface of the screen of electronic equipment. It can generally effectively protect the screen surface from damage from external forces and prevent fingerprints and dirt from appearing on the screen surface. Some protective films also have the effect of protecting eyesight and reducing the occurrence of vision problems. These screen protectors are attached to the screen of electronic equipment, generally using adhesive backing, static electricity or magnetic attraction, and currently, screen protectors using static electricity or magnetic attraction are more common.

[0003] As for the protective film connected by electrostatic means, it is completely adsorbed on the notebook screen by the static electricity of the protective film, and the adhesion is limited. When the notebook screen is opened from a closed state, the protective film may be detached from the screen due to insufficient adhesion or static electricity on the keyboard side of the notebook, affecting the user experience.

[0004] As for the protective film connected by magnetic attraction, the traditional protective film of this type is formed by setting a manganese steel sheet as a component for magnetic attraction, using a PC sheet to dig a groove, embedding the manganese steel sheet in the groove, and then fixing it with decorative parts. For products with this structure, although the manganese steel sheet can be cut by laser, the overall thickness is relatively large after assembly. If used for a notebook screen, when the notebook is closed, a large gap will be formed between the notebook screen and the keyboard, affecting the normal closure of the notebook screen, so that the notebook cannot enter the standby mode normally; moreover, the manganese steel sheet is hard in texture. If the user accidentally bends the protective film, it is easy for the manganese steel sheet to pierce the decorative parts, affecting the normal use of the protective film.

[0005] Furthermore, the protective film connected by magnetic attraction, and the components using 304 stainless steel as magnetic attraction, although they can also achieve a certain "magnetic attraction" effect, this material cannot be cut by laser, and is usually cut by a die cutter. However, this material causes great loss to the die cutter. To ensure normal processing progress, the die cutter needs to be replaced frequently. Moreover, the processing accuracy of the die cutter is low, so that the processed magnetic attraction components are prone to abnormal assembly, and the product defect rate is high.

[0006] In addition, with the development of society and the advancement of science and technology, communication electronic devices such as mobile phones, laptops, and tablets are increasingly inseparable from people's lives. As we all know, these communication electronic devices are one of the sources of electromagnetic radiation that people can be exposed to in daily life. Common electromagnetic radiation frequency bands in communication electronic devices include: radio frequency radiation (RF) and extremely low frequency radiation (ELF), both of which are non-ionizing radiation; such as Wi-Fi and Bluetooth, which work in the 2.4GHz and 5GHz frequency bands, and the electromagnetic radiation is below 6GHz, which belongs to radio frequency radiation (RF). When the measurement distance is about 1 meter, using Wi-Fi, the electromagnetic radiation is less than 6GHz, which belongs to radio frequency radiation. When Fi is transmitting data, the RF radiation intensity is usually between 30 and 50dBμV / m. When Bluetooth is used normally, the RF radiation intensity is usually between 20 and 40dBμV / m. The extremely low frequency radiation (ELF) mainly comes from the electromagnetic field generated by the power converter, processor and other electronic components inside the device when they are working. The extremely low frequency radiation generated is also far below 6GHz, and the extremely low frequency radiation intensity is usually between 10 and 25dBμV / m. However, the current screen protectors, whether they are adhesive-backed, electrostatic or magnetic, do not have the function of shielding these non-ionizing radiations. Summary of the invention

DETAILED DESCRIPTION

[0051] The present invention is further described below through various specific embodiments and in conjunction with the accompanying drawings: Specific embodiment 1:

[0053] like Figure 1-20 As shown, the utility model relates to a screen protection film for attenuating electromagnetic radiation, comprising a film body 1 and at least one adsorbed part 2, wherein the adsorbed part 2 is used to connect the film body 1 to the screen of an electronic device, the film body 1 comprises at least one anti-glare sheet 11 and at least one functional film material 13 arranged on one side of the anti-glare sheet 11 through a main adhesive layer 12, the adsorbed part 2 comprises at least one shielding layer 21, at least one auxiliary attachment part 22 connected to one side of the shielding layer 21 and a first connecting adhesive part 23 arranged on the other side of the shielding layer 21, the shielding layer 21 is used to cooperate with the film body 1 to be connected to the screen of an electronic device and attenuate the electromagnetic wave intensity of the electronic device, and the adsorbed part 2 is connected to at least one edge of the anti-glare sheet 11 through the first connecting adhesive part 23.

[0054] like Figure 12-16As shown, the anti-glare sheet 11 is composed of a first anti-glare base layer 111 and a first anti-glare coating layer 112 coated on one side of the first anti-glare base layer 111. The other side of the first anti-glare base layer 111 is connected to the main adhesive layer 12. The first anti-glare base layer 111 is a PET transparent substrate, and the thickness of the first anti-glare base layer 111 is 125±1μm; the first anti-glare coating layer 112 is a structural layer coated with AG anti-glare paint, and the thickness of the first anti-glare coating layer 112 is 3-5um; when the utility model is connected to the screen of an electronic device, the anti-glare sheet 11 can better contact with the screen of the electronic device through the first anti-glare coating layer 112, and effectively prevent the generation of Newton rings.

[0055] like Figure 12-16 As shown, one side of the functional film material 13 is provided with at least one functional coating 14, and the other side of the functional film material 13 is connected to the main adhesive layer 12. When the functional film material 13 is an anti-peeping substrate 131, the anti-peeping substrate 131 is used to prevent people other than the user from peeping at the content displayed on the screen of the electronic device. The thickness of the anti-peeping substrate 131 is 100 to 350 μm.

[0056] Furthermore, if Figure 12-16 As shown, the functional coating 14 is a third anti-glare coating 141 coated on the anti-peeping substrate 131. The third anti-glare coating 141 is a structural layer formed by coating the anti-peeping substrate 131 with AG anti-glare paint. The thickness of the third anti-glare coating 141 is 3 to 5 um, and its haze is 30%. The third anti-glare coating 141 has excellent friction resistance and fine particle size, no obvious flash point, and excellent anti-glare effect.

[0057] Furthermore, the functional coating 14 is a structural layer coated with silver ion paint, and the functional coating is used to increase the antibacterial effect of the screen; specifically, when the functional coating 14 is the third anti-glare coating 141, the silver ion paint is an AG anti-glare paint with 0.5-10% silver ions added. The addition of silver ions makes the functional coating 14 also have an antibacterial effect, because silver ions are an inorganic antibacterial substance, which is firmly adsorbed on the cell membrane by Coulomb attraction and penetrates the cell wall into the cell to coagulate the cell protein, and the cell will die due to the loss of division and proliferation ability; in addition, silver ions can also destroy the microbial electron transmission system, respiratory system, and material transmission system. When the bacteria lose their activity, the silver ions are freed from the bacteria and repeat the sterilization. Therefore, silver ions have a lasting antibacterial effect.

[0058] like Figure 12-16As shown, the main adhesive layer 12 is an optical adhesive layer, the thickness of the main adhesive layer 12 is 10μm to 60μm, the transmittance is more than 90%, and the adhesion is greater than 1000g / inch; specifically, the main adhesive layer 12 is a structural layer coated on the anti-glare sheet 11 with OCA acrylic glue (acrylic adhesive), and when the anti-peeping substrate 131, the main adhesive layer 12 and the anti-glare sheet 11 are composited, the main adhesive layer 12 can effectively fill the diamond structural layer in the anti-peeping substrate 131, thereby effectively improving the composite effect between the anti-peeping substrate 131 and the anti-glare sheet 11, and making the composite structure between the anti-peeping substrate 131 and the anti-glare sheet 11 more stable.

[0059] like Figure 1-12 As shown in , 17 and 18, when there is only one adsorbed part 2 and the adsorbed part 2 is a straight line structure, the adsorbed part 2 is connected to one edge of the anti-glare sheet 11 through the first connecting adhesive portion 23; or, when there is only one adsorbed part 2 and the adsorbed part 2 is a ring structure, the adsorbed part 2 is arranged on the four edges of the anti-glare sheet 11; or, when there are two adsorbed parts 2, each of the adsorbed parts 2 is respectively arranged on two opposite edges of the anti-glare sheet 11; or, when there are more than two adsorbed parts 2, each of the adsorbed parts 2 is respectively arranged at a distance from one edge of the anti-glare sheet 11 through the first connecting adhesive portion 23.

[0060] Furthermore, if Figure 1-11 As shown, the membrane main body 1 is provided with a membrane through hole 1a or a membrane incision 1b at the setting position of the camera of the electronic device screen. When there is only one adsorbed component 2, the adsorbed component 2 is provided with a first through hole 2a or a first incision 2b corresponding to the membrane through hole 1a or the membrane incision 1b; when there are more than two adsorbed components 2, each of the adsorbed components 2 is at least distributed on both sides of the membrane through hole 1a or the membrane incision 1b.

[0061] like Fig.12 , 17As shown in 18, the shielding layer 21 is a structural layer formed by pressing an iron-containing polymer, and the thickness of the shielding layer 21 is 10μm to 200μm; wherein, the shielding layer 21 is a sheet structure made by mixing two-dimensional magnetic powder (such as ferrite or magnetic iron nanomaterials, etc.) with chloroprene rubber, foam plastics, etc., and the iron content in the shielding layer 21 is 65-85%; generally speaking, the main electromagnetic radiation frequency of electronic devices such as laptops or tablets is below 6GHz, and the electromagnetic radiation intensity is 20-50dBμV / m. According to the current experimental test results, the two-dimensional magnetic powder and 3 0% silicone is used as a connector and pressed into a 0.1mm thick shielding sheet. The shielding effectiveness of the shielding sheet is between 20 and 40dB for the 1 to 6GHz frequency band. It can be seen that the ferrite or magnetic iron nanomaterial used in the shielding layer 21 can provide a higher electromagnetic wave attenuation efficiency in the frequency range below 6GHz. However, the screens of electronic devices such as laptops or tablets generally have magnetic elements, such as magnetic switches, which have a magnetic attraction with the shielding layer 21 of the adsorbed part 2 of the utility model, and magnetically connect the membrane body 1 to the screen of the electronic device.

[0062] like Fig.12 , 17 As shown, the auxiliary attachment part 22 includes a first attachment substrate 221 and a first self-repairing material layer 222 coated on one side of the first attachment substrate 221, and the other side of the first attachment substrate 221 is connected to the shielding layer 21 through a composite adhesive part 223; wherein, the first attachment substrate 221 is a transparent PET substrate with a thickness of 10μm to 50μm, and the first attachment substrate 221 serves as a base material for the first self-repairing material layer 222. The thickness of the first self-repairing material layer 222 is 10μm to 50μm, and the adhesion of the first self-repairing material layer 222 is 10 to 30g / inch. The main component of the first self-repairing material layer 222 is polyurethane. As a polymer with self-repairing properties, polyurethane can achieve self-healing at the molecular level when it is damaged; the first self-repairing material layer 222 of the auxiliary attachment part 22 has a certain adhesion, which can effectively cooperate with the shielding layer 21 to improve the stability of the connection between the membrane body 1 and the screen of the electronic device; and the polyurethane is washable, making the utility model more convenient to clean.

[0063] like Fig.12 , 17As shown, the composite adhesive portion 223 is a composite base layer 223b coated with at least one first glue layer 223a on both sides, wherein one first glue layer 223a is connected to the shielding layer 21, and the other first glue layer 223a is connected to the first attachment substrate 221. The thickness of the composite adhesive portion 223 is 10μm to 50μm, and the composite base layer 223b is a black PE substrate, and the thickness of the composite base layer 223b is 12±1μm; the main component of the first glue layer 223a is acrylic polymer, the thickness of the first glue layer 223a is 9±1μm, and the adhesion of the first glue layer 223a is greater than 800g / inch.

[0064] or, as Fig.18 As shown, the auxiliary attachment part 22 is composed of a second attachment substrate 22a, a fourth glue layer 22b respectively arranged on both sides of the second attachment substrate 22a, and a foam adsorption layer 22c connected to one of the fourth glue layers 22b, the other fourth glue layer 22b is connected to the shielding layer 21, and the total thickness of the auxiliary attachment part 22 is 10 to 300 μm, wherein the thickness of the second attachment substrate 22a is 50 μm ± 1 μm, the thickness of the fourth glue layer 22b is 25 μm ± 1 μm, the adhesion of the fourth glue layer 22b is greater than 800 g / inch, the thickness of the foam adsorption layer 22c is 100 μm to 200 μm, and the same material has been repeatedly tested for many times, and the average adsorption force of the foam adsorption layer 22c is 1.93 N / 25 mm, which can effectively enhance the adhesion between the adsorbed part 2 and the electric Specifically, the foam adsorption layer 22c is preferably acrylic foam, which has good adsorption properties and can be stably fixed on smooth surfaces such as glass; specifically, when the foam adsorption layer 22c is pressed by an external force, the air in the foam adsorption layer 22c can be discharged, so that the foam adsorption layer 22c has an adsorption effect similar to a suction cup on the screen of the electronic device, especially for the plastic frame set on the screen of some electronic devices, the foam adsorption layer 22c can be embedded in the surface of the plastic part when pressed by an external force. Therefore, the foam adsorption layer 22c of the auxiliary attachment part 22 can effectively cooperate with the shielding layer 21 to improve the stability of the connection between the membrane body 1 and the screen of the electronic device; in addition, the acrylic foam can be washed with water, which makes the cleaning of the utility model more convenient.

[0065] Furthermore, when applied to electronic devices that are partially or entirely free of magnetic elements, the utility model with a foam adsorption layer 22c is preferably used. When in use, it is only necessary to align the edge of the membrane body 1 with the edge of the screen of the electronic device, press the setting position of the foam adsorption layer 22c to squeeze out the air in the foam adsorption layer 22c, and the utility model can be effectively and stably connected to the screen / screen frame of the electronic device.

[0066] like Fig.12, 17 As shown in , 18, the first connecting glue part 23 is a connecting base layer 233 coated with at least one second glue layer 231 and a third glue layer 232 on both sides, the connecting base layer 233 is a black PET substrate, the thickness of the connecting base layer 233 is 10μm~50μm, the second glue layer 231 is connected to the shielding layer 21, and the third glue layer 232 is connected to the anti-glare sheet 11; wherein, the main component of the second glue layer 231 is an acrylic polymer, the thickness is 16±1μm, and the adhesion is 1700g / inch; the main component of the third glue layer 232 is an acrylic polymer, the thickness is 19±1μm, and the adhesion is 1900g / inch.

[0067] Before use, it is necessary to select the utility model that matches the size of the screen of the electronic device. When in use, it is only necessary to place the upper edge of the film body 1 of the utility model close to the upper edge of the screen of the electronic device so that the adsorbed part 2 and the magnetic elements in the screen of the electronic device are magnetically attracted to each other.
