[0025] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0026] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time.

[0027] The embodiment of the present application provides a deformation-resistant reworkable foam tape structure, comprising:
[0028] A foam layer, wherein the length direction of the foam tape is defined as a first direction, and the foam layer is arranged along the first direction;
[0029] A reinforcing layer, disposed in the foam layer and covering the foam layer;
[0030] The adhesive layer is attached to one side of the foam layer.
[0031] The above-mentioned anti-deformation reworkable foam tape structure can effectively enhance the anti-deformation ability of the foam tape by having a reinforcement layer located inside and covering the foam layer. The presence of the reinforcement layer can effectively reduce the deformation of the foam layer when subjected to force, thereby maintaining the shape stability and original performance of the tape, reducing the frequency of replacement and maintenance, and increasing the service life of the tape.
[0032] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0033] See also Figure 1-Figure 3An embodiment of the present application provides a deformation-resistant reworkable foam tape structure 100 , including a foam layer 10 , a reinforcement layer 20 , and an adhesive layer 30 .
[0034] The length direction of the foam tape is defined as a first direction, and the foam layer 10 is arranged along the first direction. The reinforcing layer 20 is arranged in the foam layer 10 and covers the foam layer 10. The adhesive layer 30 is attached to one side of the foam layer 10.
[0035] Specifically, the foam layer 10 is the main material of the foam tape, which is arranged along the length direction to provide cushioning and protection functions. The foam material has good elasticity and shock absorption performance, can effectively absorb external impact and vibration, and protect the packaged items from damage. When an external object applies pressure or impact to the foam tape, the foam layer 10 will elastically deform, converting the external impact force into internal energy, thereby protecting the items under the tape from damage.
[0036] Furthermore, the reinforcing layer 20 is located inside the foam layer 10 and covers the foam layer 10, and is used to enhance the structural stability and deformation resistance of the foam tape. The reinforcing layer 20 is embedded in the foam layer 10 in a grid shape to provide additional support and reinforcement to prevent the foam layer 10 from deforming or compressing when subjected to force. When external forces act on the tape, the reinforcing layer 20 can effectively disperse the force, reduce the deformation of the foam layer 10, and maintain the shape stability of the tape. The adhesive layer 30 is attached to one side of the foam layer 10, and is used to adhere the foam tape to the surface of the object that needs to be protected or fixed. The adhesive layer 30 has excellent adhesion properties, which can ensure that the tape is firmly bonded to the surface of the object to achieve effective fixation and protection.
[0037] In summary, the reinforcing layer 20 is located inside the foam layer 10 and covers the foam layer 10, which can effectively enhance the anti-deformation ability of the foam tape. The presence of the reinforcing layer 20 can effectively reduce the deformation of the foam layer 10 when subjected to force, thereby maintaining the shape stability and original performance of the tape, reducing the frequency of replacement and maintenance, and increasing the service life of the tape. It can play an important role in various packaging, fixing and protection applications.
[0038] In a specific embodiment, the reinforcement layer 20 is embedded in the foam layer 10 in a grid shape.
[0039] Specifically, the reinforcing layer 20 is embedded in the foam layer 10 in a grid structure to form a uniformly distributed and stable support structure. This grid structure can effectively enhance the overall strength and stability of the foam tape and improve its anti-deformation ability. When external forces act on the tape, the grid structure can evenly disperse the force, reduce the deformation and compression of the foam layer 10, and maintain the shape stability of the tape.
[0040] Furthermore, embedding the reinforcing layer 20 into the foam layer 10 can ensure that the reinforcing layer 20 and the foam layer 10 are tightly combined to form an integrated structure. This combination method can effectively prevent the reinforcing layer 20 and the foam layer 10 from being delaminated or loosened, and maintain the overall stability and performance of the tape. After the reinforcing layer 20 is embedded into the foam layer 10, it is tightly combined with the foam layer 10 by heating, pressure or other process means to form an integrated structure. In this way, the strength connection between the reinforcing layer 20 and the foam layer 10 can be ensured, thereby effectively improving the anti-deformation ability of the tape.
[0041] In a specific embodiment, the foam tape also includes a foam pad layer 40, which is arranged on the side of the foam layer 10 away from the adhesive layer 30 and extends in a vertical direction to fit the side of the foam layer 10, so as to protect the foam layer 10 from deformation due to external influences.
[0042] Specifically, the foam pad layer 40 is located on one side of the foam tape, away from the adhesive layer 30 with the foam layer 10. Its main function is to provide additional protection to prevent the foam layer 10 from being deformed by external factors. The foam pad layer 40 extends in the vertical direction and fits the side of the foam layer 10 to form a protective layer to enhance the overall stability of the foam tape. The foam pad layer 40 covers the entire foam layer 10 and can also reduce the impact of the environment (such as temperature, humidity, oxidation and other factors) and reduce the aging of the foam layer 10.
[0043] In a specific embodiment, the foam cushion layer 40 includes a waterproof layer 41 and an adhesive layer 42 which are sequentially arranged, the adhesive layer 42 is adhered to the foam layer 10 , and the waterproof layer 41 is adhered to the adhesive layer 42 .
[0044] Specifically, the waterproof layer 41 is located on the top of the foam pad layer 40, and its main function is to prevent the foam tape from being invaded by water or affected by a humid environment. The waterproof layer 41 can effectively block moisture and protect the foam layer 10 and other parts from being affected by a humid environment, thereby extending the service life of the foam tape. When the foam tape is exposed to a humid environment, the waterproof layer 41 can prevent moisture from penetrating into the foam layer 10 and other parts, thereby maintaining the dryness and stability of the tape.
[0045] Furthermore, the adhesive layer 42 is located below the waterproof layer 41, and its main function is to firmly bond the waterproof layer 41 and the foam layer 10 together to form an integrated foam cushion layer 40 structure. The adhesive layer 42 has excellent adhesive properties, which can ensure that the various components of the foam cushion layer 40 are tightly combined, thereby improving the stability and durability of the tape. Through the adhesive properties of the adhesive layer 42, the waterproof layer 41 and the foam layer 10 are tightly bonded together to form a stable structure. In this way, it can be ensured that the waterproof layer 41 will not fall off or loosen during the use of the foam tape.
[0046] In a specific embodiment, the foam cushion layer 40 further includes a support layer 43 , which is disposed on the side of the foam layer 10 and attached between the waterproof layer 41 and the adhesive layer 42 , and is perpendicular to the foam layer 10 .
[0047] Specifically, the support layer 43 is located on the side of the foam pad layer 40, and its main function is to provide additional support and reinforcement to enhance the overall structural stability of the foam tape. The support layer 43 is perpendicular to the foam layer 10 and is attached between the waterproof layer 41 and the adhesive layer 42, playing the role of supporting the foam layer 10 to prevent the foam layer 10 from being deformed or compressed when subjected to force. When the foam tape is subjected to external pressure or impact, the support layer 43 can provide additional support and reinforcement to prevent the side of the foam layer 10 from being deformed or compressed. The vertical arrangement of the support layer 43 enables it to effectively support the foam layer 10 and maintain its stable shape.
[0048] Furthermore, the support layer 43, as an important component of the foam pad layer 40, can provide additional support and reinforcement, and enhance the overall structural stability and compression resistance of the foam tape. This design can effectively prevent the foam layer 10 from deforming or compressing when subjected to force, thereby ensuring that the tape can provide reliable protection and cushioning effects in various application scenarios.
[0049] In a specific embodiment, the foam tape further includes an elastic layer 50 , and the elastic layer 50 is disposed below the reinforcing layer 20 and close to a side of the adhesive layer 30 .
[0050] Specifically, the elastic layer 50 is located below the reinforcing layer 20, close to one side of the adhesive layer 30. Its main function is to provide additional elastic support and enhance the compression resistance and buffering capacity of the foam tape. The elastic layer 50 can undergo elastic deformation when subjected to external pressure, reduce the impact of pressure on the tape, and provide a better protective effect. When external pressure acts on the foam tape, the elastic layer 50 can quickly undergo elastic deformation, absorb part of the pressure, and transfer or reduce the pressure through its elastic recovery properties, thereby protecting the items under the tape from damage. As an important component of the foam tape, the elastic layer 50 can provide additional elastic support and enhance the compression resistance and buffering capacity of the tape. This design can effectively reduce the impact of external pressure on the tape and provide a better protective effect.
[0051] In a specific embodiment, the foam layer 10 includes a first foam 11, a second foam 12 and a third foam 13 arranged in sequence, the reinforcement layer 20 is arranged between the first foam 11 and the second foam 12, and the elastic layer 50 is arranged between the second foam 12 and the third foam 13.
[0052] Specifically, the three layers of foam constitute the main structure of the foam layer 10, and their superposition provides good cushioning and protection effects. The first foam 11 plays a basic cushioning role, the second foam 12 further strengthens the cushioning performance of the tape, and the third foam 13 provides an additional protective layer. When the foam tape is subjected to external impact or pressure, the three layers of foam play a role in turn, absorbing and dispersing part of the impact force, and reducing the impact of the outside world on the protected object.
[0053] Furthermore, the reinforcing layer 20 is located between the first foam 11 and the second foam 12, and its main function is to enhance the structural stability and durability of the foam layer 10. Through the reinforcement of the reinforcing layer 20, the foam tape can better withstand external pressure and impact. When the foam tape is subjected to external pressure, the reinforcing layer 20 can effectively disperse and withstand part of the pressure, reduce the impact on the foam layer 10, and thus maintain the stability and shape of the tape.
[0054] Furthermore, the elastic layer 50 is located between the second foam 12 and the third foam 13, and its main function is to enhance the elasticity and buffering capacity of the tape. The elastic layer 50 can quickly undergo elastic deformation under the action of external pressure, reduce the pressure on the foam layer 10, and improve the buffering performance of the tape. When the foam tape is subjected to external pressure, the elastic layer 50 can quickly undergo elastic deformation, absorb and disperse part of the pressure, and reduce the impact on the items under the tape.
[0055] In a specific embodiment, the second foam 12 is disposed perpendicular to the first direction, and the third foam 13 is disposed along the first direction.
[0056] Specifically, the vertical arrangement of the second foam 12 relative to the first direction means that its fiber arrangement is perpendicular to the first direction. This arrangement helps to increase the tensile and tear resistance of the foam tape, making it stronger and more stable. When the foam tape is stretched or subjected to external forces, the vertical arrangement of the second foam 12 can effectively prevent the tape from being torn or stretched along the length direction, providing additional support and stability.
[0057] Furthermore, the third foam 13 is arranged along the first direction, that is, arranged along the length direction of the foam tape. This arrangement helps to provide additional cushioning and protection effects, and increases the foam tape's ability to absorb impact or compression in the length direction. When external impact or compression acts on the foam tape, the arrangement of the third foam 13 arranged along the length direction can effectively absorb and disperse the impact force, further reducing the deformation of the foam tape.
[0058] In a specific embodiment, the first foam 11, the second foam 12 and the third foam 13 are all of equal thickness.
[0059] Specifically, keeping the thickness of the first foam 11, the second foam 12 and the third foam 13 equal can ensure that the foam tape has similar cushioning and protective properties at different locations. This means that when the foam tape is impacted or squeezed at any point, it can provide a consistent cushioning effect to protect the packaged items from damage. When the foam tape is subjected to external impact or pressure, the thickness of the first foam 11, the second foam 12 and the third foam 13 are all equal, and they will work together to evenly disperse the impact force and reduce the impact on the packaged items.
[0060] In a specific embodiment, the foam layer 10, the reinforcement layer 20 and the elastic layer 50 are connected by hot melt.
[0061] Specifically, the foam layer 10, the reinforcement layer 20 and the elastic layer 50 are connected together by using hot melt connection technology, which can ensure a tight bond between them and enhance the overall stability and durability of the tape. Hot melt connection can fuse the various layers of material on the contact surface to form a firm connection, prevent interlayer peeling or shedding, and improve the service life and reliability of the tape. During the manufacturing process, the materials on the contact surface are melted by heating, and then pressed together to fuse at high temperature. As the temperature decreases, the melted material solidifies again to form a firm connection.
[0062] Furthermore, the foam layer 10, the reinforcement layer 20 and the elastic layer 50 are connected together by hot-melt connection technology, which can ensure the stable connection between the layers during the use of the tape, and improve the durability and reliability of the tape. This design is suitable for application scenarios that require long-term use or withstand large impact forces, and can ensure that the tape can play its protective and buffering role in a long-term and stable manner.
[0063] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
