[0003] Existing UV film tapes have significant defects in performance and function:
[0004] First, it is difficult to balance toughness and strength. The substrate and adhesive layer of traditional UV film tape are mostly single material systems, which are prone to breakage when subjected to external force stretching or bending. Especially in the process of bonding flexible electronic components, tape damage may cause components to fall off or become contaminated.
[0005] Secondly, most existing UV film tapes only have basic adhesion control functions and lack additional properties such as antistatic and antibacterial properties, making them difficult to adapt to the complex environment of high-end electronic manufacturing.
[0006] To address this, a high-toughness UV film tape based on nanomaterial reinforcement is proposed. Utility Model Content

Especially in the process of bonding flexible electronic components, tape damage may lead to component detachment or contamination; existing UV film tapes mostly only have basic adhesion control functions and lack additional properties such as antistatic and antibacterial properties, making it difficult to adapt to the complex environment of high-end electronic manufacturing.

[0017] 1. This application utilizes the dispersion and strengthening effect of nanomaterials through the synergistic design of the nano-reinforced substrate layer and the UV-sensitive adhesive layer. While ensuring the basic strength of the tape, it significantly improves its tear resistance and bending resistance, avoiding damage during frequent operation. It is suitable for scenarios with high toughness requirements, such as flexible electronic components. Furthermore, the interface transition layer enhances the bonding force between the nano-reinforced substrate layer and the UV-sensitive adhesive layer, reducing the risk of delamination.

Detailed Implementation
[0024] 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.
[0025] Please see Figure 1-4 The present invention provides the following technical solution:
[0026] A high-toughness UV film tape based on nanomaterial reinforcement includes a tape body 1. The tape body 1 includes a release layer 2, a UV-sensitive adhesive layer 3, a nano-reinforced substrate layer 4, and a functional auxiliary layer 5. The edges of the tape body 1 are provided with nano-sealing edges 6. The release layer 2, UV-sensitive adhesive layer 3, nano-reinforced substrate layer 4, and functional auxiliary layer 5 are arranged sequentially from bottom to top.
[0027] In this embodiment, the tape body 1 adopts a layered structure consisting of a release layer 2, a UV-sensitive adhesive layer 3, a nano-reinforced substrate layer 4, and a functional auxiliary layer 5, combined with a nano-sealing edge 6, to achieve synergistic effects of enhanced toughness, functional integration, and structural protection. The layered design allows each layer to focus on specific functions (such as nano-reinforcement, antibacterial and antistatic properties), resulting in a systematic improvement. The nano-sealing edge 6 specifically addresses the problem of easily damaged edges and prevents environmental erosion at the interlayer interfaces. The overall structure overcomes the shortcomings of traditional UV film tapes, such as insufficient toughness and limited functionality, making it suitable for complex scenarios such as high-end electronic manufacturing.
[0028] Specifically, such as Figure 2 As shown, release layer 2 is composed of a fluorine release film and its surface is coated with a release agent coating containing nano-silica.
[0029] Specifically, such as Figure 2 As shown, the UV-sensitive adhesive layer 3 is composed of an organosilicon-modified acrylate system.
[0030] Specifically, such as Figure 2 As shown, the nano-reinforced substrate layer 4 is composed of a modified PET film.
[0031] In this embodiment: the release layer 2 uses a fluorinated release film coated with a release agent coating containing nano-silica. The fluorinated release film itself has low surface energy and weather resistance, while the nano-silica enhances the wear resistance and stability of the release agent, ensuring uniform release effect during storage and use of the tape. This avoids adhesive residue or peeling difficulties caused by wear of the release layer 2, improving ease of operation. The UV-sensitive adhesive layer 3 uses an organosilicon-modified acrylate system. The organosilicon component gives the adhesive layer excellent flexibility, while the acrylate component ensures its sensitivity to ultraviolet light. The combination of the two gives the adhesive layer good adhesion in the initial state, and the adhesion can be precisely controlled after UV irradiation, while maintaining appropriate toughness to avoid tearing during peeling, thus balancing functionality and durability. The nano-reinforced substrate layer 4 uses a modified PET film. The modification treatment improves the impact resistance and flexibility of PET. As the basic load-bearing layer of the tape, it can provide stable structural support and is not easily broken when stretched or bent, solving the problem of insufficient toughness of traditional PET substrates and laying the foundation for improving the overall toughness of the tape.
[0032] Specifically, such as Figure 3 As shown, the functional auxiliary layer 5 includes a nano-silver antibacterial layer 51 and an antistatic coating 52, which are arranged sequentially from bottom to top at the bottom of the nano-reinforced substrate layer 4.
[0033] Specifically, such as Figure 3 As shown, the antistatic coating 52 contains nano-conductive powder, and the nano-conductive powder is graphene or carbon nanotubes.
[0034] In this embodiment: the functional auxiliary layer 5 is composed of a nano-silver antibacterial layer 51 and an antistatic coating 52, and is layered at the bottom of the nano-reinforced substrate layer 4. The nano-silver antibacterial layer 51 can inhibit bacterial growth and is suitable for hygiene-sensitive scenarios such as medical electronics. The antistatic coating 52 can release accumulated static electricity and prevent static electricity from damaging precision electronic components. The two layers work together to give the tape protective properties in addition to its basic adhesive function, which can meet diverse needs.
[0035] Specifically, such as Figure 2 As shown, the nano-sealing edge 6 is made of nano-silicone rubber and wraps the interlayer interface of the edge of the tape body 1.
[0036] Specifically, such as Figure 4 As shown, an interface transition layer 7 is provided between the nano-reinforced substrate layer 4 and the UV-sensitive adhesive layer 3. The interface transition layer 7 is a nano-silane coupling agent adhesive layer.
[0037] In this embodiment: the nano-sealing edge 6 is made of nano-silicone rubber and wraps the interlayer interface. The nano-silicone rubber has excellent flexibility and sealing properties, which can closely fit the edge of the tape to prevent moisture and dust from entering from the interlayer gaps. At the same time, it can alleviate stress concentration at the edge when bending, avoid edge cracking, and extend the overall service life of the tape. A nano-silane coupling agent interface transition layer 7 is provided between the nano-reinforced substrate layer 4 and the UV-sensitive adhesive layer 3. The silane coupling agent can improve the interfacial compatibility of the two materials, enhance the interlayer bonding force, reduce the delamination phenomenon caused by temperature changes or external forces, ensure that the layers of the tape work together, and maintain the overall performance stability.
[0038] Working principle: When using the tape body 1, the release layer 2 is first peeled off from the surface of the UV-sensitive adhesive layer 3. The nano-silica-reinforced release agent coating ensures a smooth peeling process with no adhesive residue. The exposed UV-sensitive adhesive layer 3, thanks to the initial tack of the silicone-modified acrylate system, can quickly adhere to the surface of the object to be bonded (such as electronic components, precision parts, etc.). During the bonding process, the modified PET film of the nano-reinforced substrate layer 4 provides structural support, preventing the tape from breaking due to stretching or bending. The antistatic coating 52 of the functional auxiliary layer 5 immediately releases the static electricity generated during the operation, preventing static electricity from damaging electronic components. After bonding, the tape enters a long-term use state: the modified PET film in the nano-reinforced substrate layer 4 works synergistically with the nano-reinforcement material, giving the tape excellent tear resistance and bending resistance. Even under frequent vibration or external force, it can still maintain structural integrity, preventing the object to be bonded from falling off or becoming contaminated due to tape damage. Furthermore, the nano-reinforced substrate layer 5... The antibacterial layer 51 continuously inhibits the growth of bacteria on the surface, making it particularly suitable for applications with high hygiene requirements, such as medical electronics. The nano-sealing edge 6 tightly wraps the interlayer interface of the tape edge, preventing the intrusion of contaminants such as moisture and dust, avoiding interlayer delamination, and relieving edge stress concentration, thus extending the tape's lifespan. The nano-silane coupling agent in the interface transition layer 7 ensures a tight bond between the nano-reinforced substrate layer 4 and the UV-sensitive adhesive layer 3, preventing delamination caused by changes in ambient temperature and humidity and maintaining overall performance stability. When the tape needs to be removed, the UV-sensitive adhesive layer 3 is irradiated with ultraviolet light: the organosilicon-modified acrylate system undergoes a cross-linking reaction under ultraviolet light, precisely reducing its adhesion. At this time, the UV-sensitive adhesive layer 3 still maintains moderate toughness, and combined with the tear resistance of the nano-reinforced substrate layer 4, there will be no tape breakage or adhesive residue during the peeling process. After peeling, the antibacterial and antistatic functions of the functional auxiliary layer 5 are removed along with the entire tape, avoiding secondary contamination of the pasted surface.
[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
