Description

Technical Field

[0001] This application relates to the technical field of aluminum foil materials, and in particular to a double-sided self-adhesive aluminum foil with a thickened layer. Background Technology

[0002] Aluminum foil is a hot stamping material made by directly rolling metallic aluminum into thin sheets. Its hot stamping effect is similar to that of pure silver foil, hence it is also called imitation silver foil. Because aluminum is soft, ductile, and has a silvery-white luster, the rolled sheets can be laminated onto offset paper with substances such as sodium silicate to create aluminum foil sheets, which can then be printed on. Currently, aluminum foil composite materials are increasingly widely used in the construction, industrial, and electronics fields, especially in heat insulation, thermal insulation, and electromagnetic shielding.

[0003] In related technologies, Chinese Patent Publication No. CN220887395U discloses a double-sided hot-melt self-adhesive aluminum foil, relating to the field of aluminum foil material technology. It includes an outer coating layer with a sound-insulating core inside. Two sets of hot-melt adhesive are bonded to the inner side of the outer coating layer, located at the upper and lower ends of the inner side. An aluminum foil layer is provided on one side of the hot-melt adhesive, and an absorbent layer is fixedly connected to the side of the aluminum foil layer away from the hot-melt adhesive. This invention utilizes an outer coating layer made of polytetrafluoroethylene (PTFE) with an interwoven fiber structure, providing good heat resistance. When a hot air gun heats both sides of the aluminum foil, the hot-melt adhesive on the inner side melts, penetrating the PTFE fiber material, thus enabling adhesion to walls and substrates. When not in use, the outer coating layer provides a barrier effect, preventing the hot-melt adhesive from sticking to the hands.

[0004] Regarding the aforementioned technologies, the inventors discovered that when in use, the aluminum foil layer is made of nylon, which is not conducive to improving its aging resistance and heat resistance. Utility Model Content

[0005] To address the issue of the inconvenience in achieving aging and heat resistance through aluminum foil layers, this application provides a double-sided self-adhesive aluminum foil with a thickened layer.

[0006] This application provides a double-sided self-adhesive aluminum foil with a thickened layer, using the following technical solution: A double-sided self-adhesive aluminum foil with a thickened layer includes a sound-insulating core, absorbent layers fixedly connected to both sides of the sound-insulating core, an aluminum foil layer body fixedly connected to the side of the aluminum foil layer body away from the sound-insulating core, a hot melt adhesive fixedly connected to the side of the aluminum foil layer body away from the absorbent layer, an outer cover body fixedly connected to the surface of the hot melt adhesive, the aluminum foil layer body including an aluminum foil layer substrate and a first reinforcing component, the surface of the aluminum foil layer substrate being provided with the first reinforcing component, and the outer cover body including an outer cover layer substrate and a second reinforcing component, the surface of the outer cover layer substrate being provided with the second reinforcing component.

[0007] Optionally, the strengthening component includes an anti-aging layer disposed on the surface of the aluminum foil substrate.

[0008] By adopting the above technical solution, the anti-aging layer effectively improves the anti-aging effect of the aluminum foil layer itself. This anti-aging layer is a performance layer; by adding anti-aging agents to the raw materials of the aluminum foil layer, its service life can be effectively extended. The anti-aging agents can capture free radicals, prevent the breakage of polymer chains, and thus slow down the aging process.

[0009] Optionally, a high-temperature resistant layer is provided on the side of the anti-aging layer away from the aluminum foil substrate.

[0010] By adopting the above technical solution, the high-temperature resistant layer can be used to improve the high-temperature resistance of the aluminum foil layer. The high-temperature resistant layer is an effect layer. By combining nanomaterials (such as nano-silica, nano-alumina, etc.) with the raw materials of the aluminum foil layer, a composite material with excellent heat resistance can be formed. This composite material can still maintain good mechanical properties and stability at high temperatures.

[0011] Optionally, a toughening layer is provided on the side of the high-temperature resistant layer away from the anti-aging layer.

[0012] By adopting the above technical solution, the toughness layer facilitates the toughness of the aluminum foil layer body. The toughness layer is an effect layer. By adding carbon nanotubes and polyvinylidene fluoride to the aluminum foil layer body, the toughness of the raw materials of the aluminum foil layer body can be significantly improved.

[0013] Optionally, the second reinforcement component includes a strength layer disposed on the surface of the outer coating substrate.

[0014] By adopting the above technical solution, the strength layer is made easier to pass through the strength of the outer coating body, which is the effect layer. By adding glass fiber to the raw materials of the outer coating body, its strength is improved.

[0015] Optionally, an anti-corrosion layer is provided on the side of the strength layer away from the outer coating substrate.

[0016] By adopting the above technical solution, the anti-corrosion layer can be made easier to pass through the anti-corrosion effect of the outer coating body. By adding fluorocarbon coating or silane coupling agent to the raw materials of the outer coating body, the corrosion resistance of the material can be significantly improved.

[0017] In summary, this application includes the following beneficial technical effects: 1. By setting up the first reinforcement component, the aging resistance and heat resistance of the aluminum foil layer are improved. The anti-aging layer improves the aging resistance of the aluminum foil layer itself. The high-temperature resistant layer improves the heat resistance of the aluminum foil layer itself. The toughness layer improves the toughness of the aluminum foil layer itself.

[0018] 2. By setting up the second reinforcement component, the corrosion resistance of the outer coating is improved. The corrosion-resistant layer improves the corrosion resistance of the outer coating, and the strength layer improves the strength of the outer coating. Attached Figure Description

[0024] The anti-aging layer 321 enhances the anti-aging effect of the aluminum foil layer 3. As an effective layer, adding anti-aging agents to the raw materials of the aluminum foil layer 3 effectively extends its service life. These anti-aging agents can capture free radicals, prevent the breakage of polymer chains, and thus slow down the aging process.

By combining nanomaterials (such as nano-silica, nano-alumina, etc.) with the raw materials of the aluminum foil substrate 3, a composite material with excellent heat resistance can be formed. This composite material can still maintain good mechanical properties and stability at high temperatures.

[0026] Specifically, a toughness layer 323 is provided on the side of the high-temperature resistant layer 322 away from the anti-aging layer 321. The toughness layer 323 facilitates the toughness of the aluminum foil layer body 3. The toughness layer 323 is an effect layer. By adding carbon nanotubes and polyvinylidene fluoride to the aluminum foil layer body 3, the toughness of the raw materials of the aluminum foil layer body 3 can be significantly improved.

[0027] The implementation principle of the enhanced effect component 32 is as follows: The anti-aging layer 321 enhances the anti-aging effect of the aluminum foil body 3. The anti-aging layer 321 is an effect layer; adding anti-aging agents to the raw materials of the aluminum foil body 3 effectively extends its service life. Anti-aging agents can capture free radicals, prevent the breakage of polymer chains, and thus slow down the aging process. The high-temperature resistant layer 322 enhances the high-temperature resistance of the aluminum foil body 3. The high-temperature resistant layer 322 is an effect layer; combining nanomaterials (such as nano-silica, nano-alumina, etc.) with the raw materials of the aluminum foil body 3 forms a composite material with excellent heat resistance. This composite material maintains good mechanical properties and stability at high temperatures. The toughness layer 323 enhances the toughness of the aluminum foil body 3. The toughness layer 323 is an effect layer; adding carbon nanotubes and polyvinylidene fluoride to the aluminum foil body 3 significantly improves the toughness of the raw materials. Therefore, during use, the device effectively enhances the anti-aging and high-temperature resistance of the aluminum foil body 3, while also improving its toughness.

[0028] Specifically, the enhanced effect component 2 52 includes a strength layer 521, which is disposed on the surface of the outer coating substrate 51.

[0029] The strength layer 521 facilitates the strength of the outer cover body 5, which is an effect layer. Its strength is improved by adding glass fiber to the raw materials of the outer cover body 5.

[0030] Specifically, an anti-corrosion layer 522 is provided on the side of the strength layer 521 away from the outer coating substrate 51. The anti-corrosion layer 522 facilitates the anti-corrosion effect of the outer coating body 5. By adding fluorocarbon coatings or silane coupling agents to the raw materials of the outer coating body 5, the corrosion resistance of the material can be significantly improved.

[0031] The implementation principle of the enhanced effect component 2 52 is as follows: the strength layer 521 facilitates the strength of the outer cover body 5, which is an effect layer. By adding glass fiber to the raw materials of the outer cover body 5, its strength is improved. The anti-corrosion layer 522 facilitates the anti-corrosion effect of the outer cover body 5. By adding fluorocarbon coating or silane coupling agent to the raw materials of the outer cover body 5, the corrosion resistance of the material can be significantly improved, so that the device can easily pass through the strength and anti-corrosion effect of the outer cover body 5 when in use.

[0032] The structure and working principle of the sound-insulating core 1, water-absorbing layer 2, aluminum foil layer body 3, hot-melt adhesive 4, and outer covering layer body 5 in this utility model have been disclosed in a double-sided hot-melt self-adhesive aluminum foil disclosed in Chinese Patent Publication No. CN220887395U. Its working principle is that the water-absorbing layer 2 and the aluminum foil layer body 3 are fixedly set at the upper and lower ends of the sound-insulating core 1 respectively. The sponge-material water-absorbing layer 2 has a certain moisture-absorbing effect, and the nylon-material aluminum foil layer body 3 can prevent external moisture from entering the sound-insulating core 1, thus effectively improving the moisture-proof effect. Furthermore, the sound-insulating core 1 itself has folded surfaces; the wavy folded surfaces provide better sound insulation. Its flexibility allows for easy folding. When bonding is required, the surface of the outer cover body 5 is heated with a hot air gun. Because the outer cover body 5 is made of polytetrafluoroethylene and the fibers of the outer cover body 5 are interwoven, the outer cover body 5 provides a protective barrier for the inner hot melt adhesive 4. When bonding is not required, handling the outer cover body 5 can prevent fingers from coming into contact with the hot melt adhesive 4 and causing it to stick to the hands. After the outer cover body 5 is heated with a hot air gun, the hot melt adhesive 4 becomes more fluid and penetrates through the outer cover body 5, thus achieving the bonding and fixing operation between the aluminum foil material and the wall or substrate.

[0033] The implementation principle of a double-sided self-adhesive aluminum foil with a thickened layer in this application embodiment is as follows: A water-absorbing layer 2 and an aluminum foil layer body 3 are fixedly arranged at the upper and lower ends of the sound-insulating core 1, respectively. The sponge-material water-absorbing layer 2 has a certain moisture-absorbing effect, and the nylon-material aluminum foil layer body 3 can prevent external moisture from entering the sound-insulating core 1, thus effectively improving the moisture-proof effect. The sound-insulating core 1 itself has a folded surface; the wavy folded surface provides good flexibility for the sound-insulating core 1, facilitating folding operations. When bonding is required, the surface of the outer covering body 5 is heated by a hot air gun. Since the outer covering body 5 is made of polytetrafluoroethylene and the fibers of the outer covering body 5 are interwoven, the outer covering body 5 provides a protective barrier for the inner hot-melt adhesive 4. When adhesive is not required, handling the outer cover body 5 prevents fingers from coming into contact with the hot melt adhesive 4, thus avoiding stickiness. After the hot air gun heats the outer cover body 5, the hot melt adhesive 4 becomes more fluid, allowing it to penetrate the outer cover body 5. At this point, the aluminum foil material can be bonded and fixed to the wall or substrate. The first enhancement component 32 facilitates the anti-aging and heat resistance of the aluminum foil layer body 3, while the second enhancement component 52 facilitates the strength and corrosion resistance of the outer cover body 5. When the first enhancement component 32 is used, the anti-aging layer 321 enhances the anti-aging effect of the aluminum foil layer body 3. The anti-aging layer 321 is an effect layer, and the addition of anti-aging agents to the raw materials of the aluminum foil layer body 3 can effectively extend its service life. Anti-aging agents can capture free radicals and prevent the breakage of polymer chains, thereby slowing down the aging process. The high-temperature resistant layer 322 facilitates the improvement of the high-temperature resistance of the aluminum foil body 3. The high-temperature resistant layer 322 is an effect layer. By combining nanomaterials (such as nano-silica, nano-alumina, etc.) with the raw materials of the aluminum foil body 3, a composite material with excellent heat resistance can be formed. This composite material can maintain good mechanical properties and stability at high temperatures. The toughness layer 323 facilitates the improvement of the toughness of the aluminum foil body 3. The toughness layer 323 is an effect layer. By adding carbon nanotubes and polyvinylidene fluoride to the aluminum foil body 3, the toughness of the aluminum foil body 3 can be significantly improved. The toughness of the raw material of body 3 makes it easy for the device to resist aging and high temperature through the aluminum foil layer body 3 during use. At the same time, it also makes it easy to strengthen the effect component 2 52 during use. The strength layer 521 makes it easy to strengthen the outer cover body 5. It is an effect layer. By adding glass fiber to the raw material of the outer cover body 5, its strength is improved. The anti-corrosion layer 522 makes it easy to protect the outer cover body 5 from corrosion. By adding fluorocarbon coating or silane coupling agent to the raw material of the outer cover body 5, the corrosion resistance of the material can be significantly improved. This makes it easy for the device to protect the strength and corrosion resistance of the outer cover body 5 during use.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
