Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically to an antistatic light-shielding adhesive tape. Background Technology

[0002] Light-shielding tape can be used to fix the LCD and backlight modules of electronic devices. For electronic devices, fixing the LCD panel and backlight module is crucial; only by properly fixing these components can the normal operation of the electronic device be ensured. Light-shielding tape can be used to block light. During the use of electronic devices, it is essential to use light-shielding tape to shield them from light. Generally, light-shielding tape has a matte black surface. This matte black surface also offers several advantages, such as scratch resistance. Good scratch resistance not only makes the tape aesthetically pleasing and doesn't affect the user experience, but also provides some protection for the electronic device. The matte black surface of the light-shielding tape also has a certain fingerprint-resistant function, meaning that fingerprints will not be left on the electronic device during use.

[0003] Currently, operators use tape in the production, assembly, and packaging of electronic devices. However, minute electrostatic discharges during use may damage sensitive electronic components. Furthermore, some items adhered with tape may be sensitive to light, and exposure to light may cause these items to undergo chemical reactions, deteriorate, or experience performance degradation. Utility Model Content

[0004] The purpose of this invention is to provide an antistatic light-shielding tape to solve the problems mentioned in the background art. Currently, operators use tape in the production, assembly and packaging of electronic devices, but small electrostatic discharges during use may damage sensitive electronic components. In addition, some items attached to the tape may be sensitive to light, and light exposure may cause these items to undergo chemical reactions, deteriorate or degrade in performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an antistatic light-shielding tape, comprising an adhesive layer, a conductive layer fixedly installed on the top of the adhesive layer, an antistatic agent disposed inside the conductive layer, an antistatic isolation layer fixedly installed on the top of the conductive layer, an antistatic coating fixedly installed on the top of the antistatic isolation layer, a light-shielding layer fixedly installed on the top of the antistatic coating, a lower film layer fixedly installed on the top of the light-shielding layer, a light-shielding paper fixedly installed on the top of the lower film layer, and an upper film layer fixedly installed on the top of the light-shielding paper.

[0006] Preferably, a high-temperature resistant layer is fixedly installed on the top of the upper thin film layer, and the material of the high-temperature resistant layer can be Teflon.

[0007] Preferably, a substrate layer is fixedly installed on the top of the high-temperature resistant layer, and the substrate layer may be made of polyvinyl chloride.

[0008] Preferably, a coating layer is fixedly installed on the top of the substrate layer, and the coating layer is made of aluminum.

[0009] Preferably, a protective layer is fixedly installed on the top of the coating layer, and the material of the protective layer can be a polypropylene film.

[0010] Preferably, the lower film layer and the upper film layer have the same size, and the material of the lower film layer and the upper film layer can be polystyrene.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This type of antistatic light-shielding tape incorporates an antistatic agent in its adhesive layer during daily use. This agent forms a conductive layer on the tape surface, guiding static electricity to the ground and preventing its accumulation. The antistatic agent in the conductive layer reduces the tape's surface resistance, allowing charges to flow rapidly and preventing static buildup. Simultaneously, the antistatic isolation layer isolates the tape from external objects, reducing the chance of static electricity generation. Its own antistatic properties also help prevent static accumulation. The antistatic coating forms a uniform conductive network on the tape surface, quickly dissipating generated static electricity. This multi-layered design enhances the antistatic effect.

[0013] This antistatic light-shielding tape, during daily use, utilizes metal oxide components within the light-shielding layer to absorb and scatter light, converting it into heat energy or causing multiple reflections within the light-shielding layer, thereby preventing light from passing through the tape and achieving a light-shielding effect. An appropriate amount of light-shielding agent is added to the adhesive layer, ensuring thorough mixing with the adhesive. The coating layer reflects light, thus achieving excellent light-shielding performance. Furthermore, the synergistic effect of the multi-layered structure—the lower film layer, the light-shielding paper, and the upper film layer—further enhances the tape's light-shielding performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: an antistatic light-shielding tape, comprising an adhesive layer 1, in which a light-shielding agent and an antistatic agent are added; a conductive layer 2 is fixedly installed on the top of the adhesive layer 1, and an antistatic agent is disposed inside the conductive layer 2. By adding the antistatic agent to the conductive layer 2, the surface resistance of the tape is reduced, allowing charges to flow rapidly on the tape surface and preventing static electricity accumulation. When the tape comes into contact with other objects and generates static electricity through friction, the conductive layer 2 can conduct the static electricity away, preventing damage to sensitive equipment or items. An antistatic isolation layer 3 is fixedly installed on the top of the conductive layer 2. The antistatic isolation layer 3 can be made of a thin film material with antistatic properties, such as a metal-plated polyester film, as the isolation layer. It can isolate the tape from external objects, reducing the chance of frictional charging, and its own antistatic properties also help prevent static electricity accumulation. An antistatic coating 4 is fixedly installed on the top of the antistatic isolation layer 3. The antistatic coating 4 contains conductive polymer materials or nano-sized conductive particles, which can... A uniform conductive network is formed on the surface, which can quickly dissipate static electricity and protect the tape, improving its weather resistance and abrasion resistance. A light-shielding layer 5 is fixedly installed on the top of the antistatic coating 4. The interior of the light-shielding layer 5 contains metal oxides. The carbon black, metal oxides and other components in the light-shielding layer 5 can absorb and scatter light, converting the light into heat energy or causing the light to be reflected multiple times inside the light-shielding layer 5, thereby preventing light from passing through the tape and achieving a light-shielding effect. A lower film layer 6 is fixedly installed on the top of the light-shielding layer 5, a light-shielding paper 7 is fixedly installed on the top of the lower film layer 6, and an upper film layer 8 is fixedly installed on the top of the light-shielding paper 7. The polystyrene in the lower film layer 6 and the upper film layer 8 has good rigidity and insulation. The synergistic effect of the multi-layer structure of the lower film layer 6, the light-shielding paper 7 and the upper film layer 8 further improves the light-shielding performance of the tape through the light-shielding paper 7. A high-temperature resistant layer 9 is fixedly installed on the top of the upper film layer 8. The material of the high-temperature resistant layer 9 can be Teflon. The Teflon material improves the high-temperature resistance and thus improves its functionality.

[0021] A substrate layer 10 is fixedly installed on top of the high-temperature resistant layer 9. The substrate layer 10 can be made of polyvinyl chloride (PVC). The PVC in the substrate layer 10 can provide the basic strength and toughness of the tape. A coating layer 11 is fixedly installed on top of the substrate layer 10. The coating layer 11 is made of aluminum. The coating layer 11 uses vacuum coating technology to coat a metal film on the surface of the tape. The metal film can reflect light, thereby achieving good light-blocking performance. A protective layer 12 is fixedly installed on top of the coating layer 11. The protective layer 12 can be made of polypropylene film. It is used to protect the adhesive layer 1 and prevent it from being contaminated or damaged before storage and use. The lower film layer 6 has the same size as the upper film layer 8. The lower film layer 6 and the upper film layer 8 can be made of polystyrene. They are generally colorless and transparent and have good rigidity and insulation.

[0022] Working principle: The adhesive layer 1 contains a light-blocking agent and an antistatic agent, which can conduct static electricity to the ground, thus preventing static accumulation and providing a certain degree of light blocking. Subsequently, the antistatic agent added to the conductive layer 2 reduces the surface resistance of the tape. Then, the antistatic isolation layer 3 isolates the tape from external objects, reducing the chance of frictional charging, while its own antistatic properties also help prevent static accumulation. The antistatic coating 4 forms a uniform conductive network on the tape surface, quickly dissipating generated static electricity. Furthermore, the metal oxide components inside the light-blocking layer 5... The adhesive layer 1 absorbs and scatters light, thereby preventing light from passing through the tape and achieving a light-blocking effect. The light-blocking agent in the adhesive layer 1 can be fully mixed with the adhesive to achieve light blocking. At the same time, the synergistic effect of the multi-layer structure of the lower film layer 6, the light-blocking paper 7 and the upper film layer 8 improves the light-blocking performance of the tape. The upper film layer 8 can also improve the high-temperature resistance. The substrate layer 10 provides the basic strength and toughness of the tape. The coating layer 11 can reflect light, thereby achieving good light-blocking performance. The protective layer 12 is used to protect the adhesive layer 1 and prevent it from being contaminated or damaged before storage and use.
