[0025] In some embodiments, referring to Figures 1 to 5 the adhesive layer 3 comprises a first pressure-sensitive adhesive layer 32, a second pressure-sensitive adhesive layer 33 and a heat-sensitive adhesive 31, the first pressure-sensitive adhesive layer 32 is arranged on one end of the base material 2 away from the protective layer 4, the second pressure-sensitive adhesive layer 33 is arranged on one end of the first pressure-sensitive adhesive layer 32 away from the base material 2, a plurality of through holes are arranged on the second pressure-sensitive adhesive layer 33, and the heat-sensitive adhesive 31 is arranged on one end of the second pressure-sensitive adhesive layer 33 away from the first pressure-sensitive adhesive layer 3 through the through holes.

[0026] In this way, when a user attaches the sticker to an attachment surface, the first pressure-sensitive adhesive layer 32 ensures that the base material 2 and the adhesive layer 3 are tightly bonded, and at the same time, by arranging the through holes on the second pressure-sensitive adhesive layer 33, the heat-sensitive adhesive 31 increases the contact area between the second pressure-sensitive adhesive layer 33 through the through holes, and when the user wants to remove the sticker from the attachment surface, by heating the sticker, the heat-sensitive adhesive 31 loses adhesion, so that the sticker is removed from the attachment surface without leaving glue residues, and in this way, the pressure-sensitive adhesive layer 3 can provide instant adhesion after being attached, without waiting for the drying time, and can better bond the base material 2 and the adhesive layer 3, at the same time, the heat-sensitive adhesive 31 can quickly solidify after being heated, providing fast adhesion, the heat-sensitive adhesive 31 can usually provide strong adhesion after being solidified, the heat-sensitive adhesive 31 usually has good temperature resistance and is suitable for application scenarios that require high temperature resistance, the heat-sensitive adhesive 31 can be adjusted by adjusting the heating temperature and time to adapt to different adhesion requirements, and the heat-sensitive adhesive 31 is suitable for an automatic production line and can improve production efficiency.

[0027] In some embodiments, referring to Figures 1 to 4 the first pressure-sensitive adhesive layer 32 is further provided with a magnetic assembly 5, the magnetic assembly 5 comprises a magnetic layer 51, a magnetic matching layer 52 and a second base paper 53, the magnetic layer 51 is arranged on one end of the first pressure-sensitive adhesive layer 32 away from the second pressure-sensitive adhesive layer 33, the magnetic layer 51 is provided with a connecting hole, the second base paper 53 is arranged on the magnetic layer 51 through the connecting hole, and the magnetic matching layer 52 is arranged on one end of the magnetic layer 51 away from the first pressure-sensitive adhesive layer 32.

[0028] With such an arrangement, the user can use the magnetic attraction assembly 5 to remove the content part of the sticker when the user does not want to remove it by heating, by bringing the magnetic attraction layer 51 to the magnetic cooperation layer 52, taking the content part of the sticker with the substrate 2, replacing the content part of the sticker as needed, reducing environmental pollution, and the magnetic sticker can be easily attached and removed without damaging the sticker or the surface. This makes them reusable multiple times, and if the information needs to be replaced or updated, the magnetic sticker can be easily removed and replaced with a new one, the magnetic sticker can be easily rolled up and stored, without taking up too much space, and it is not easy to be damaged during transportation. Compared with one-time adhesive, the magnetic sticker provides a more environmentally friendly option because they can be used for a long time, reducing waste, and because of the inclusion of the magnetic cooperation layer 52, this sticker can be quickly and easily installed and adjusted without the need for additional adhesive or complex installation processes.

[0029] In some embodiments, referring to Figures 2 to 3 , the substrate 2 includes a first base paper 21, a printing layer 22, a weather-resistant layer 23, and a thermal-sensitive layer 24, the first base paper 21 is arranged on the end of the magnetic cooperation layer 52 away from the magnetic attraction layer 51, the printing layer 22 is arranged on the end of the first base paper 21 away from the magnetic cooperation layer 52, the weather-resistant layer 23 is arranged on the end of the printing layer 22 away from the first base paper 21, the thermal-sensitive layer 24 is arranged on the end of the weather-resistant layer 23 away from the printing layer 22, and the PET layer 7 is arranged on the printing layer 22.

[0030] With such an arrangement, the weather-resistant layer 23 can protect the printing layer 22 from environmental factors, extending the service life of the sticker, the printing layer 22 provides clear images and text, and the PET layer 7 can provide a smooth surface, helping to achieve high-quality printing effects. The PET layer 7 not only provides a smooth surface, but also helps to protect the printing layer 22 from scratches, wear and other physical damage, the thermal-sensitive layer 24 allows the sticker to react to temperature changes, which is very useful in applications that require temperature indication or heat activation, the first base paper 21 serves as the structural foundation, providing the necessary mechanical strength and stability to ensure the durability of the sticker in various applications, this structure allows for a high degree of customization, including different sizes, shapes, colors, and functions to meet specific market demands or customer requirements, this multi-level structure allows the sticker to adapt to different environmental and application requirements, from indoor decoration to outdoor signage.

[0031] In some embodiments, referring to Figures 2 to 3 , the protective layer 4 includes a waterproof layer 41 and a transparent protective layer 42, the waterproof layer 41 is arranged on the end of the thermal-sensitive layer 24 away from the weather-resistant layer 23, and the transparent protective layer 42 is arranged on the end of the waterproof layer 41 away from the thermal-sensitive layer 24, and the transparent protective layer 42 is provided with a silicone oil coating 43.

[0033] In some embodiments, referring to Figures 1 to 5 , the release paper 1 is provided with a network of raised bumps 6.

[0034] In this way, the network of raised bumps 6 can reduce the contact area between the release paper 1 and the sticker, thereby reducing the adhesion. This makes it easier to peel the sticker off the release paper 1, reducing the risk of tearing or damage caused by excessive adhesion. Since the network of raised bumps 6 makes it easier to peel off the sticker, it can speed up the production line and improve production efficiency. The operator can handle the sticker faster, reducing production time and cost. The structure of the network of raised bumps 6 helps to exclude air during the application of the sticker, reducing the formation of air bubbles. At the same time, it can also help the sticker to be more evenly attached to the target surface, reducing wrinkles.

[0035] The implementation principle of the sticker convenient to remove by heating is as follows: the user removes the sticker on the release paper 1 with the netted convex 6, and pastes the sticker on the attached surface. The first pressure-sensitive adhesive layer 32 ensures the close adhesion of the substrate 2 and the adhesive layer 3. Meanwhile, the through hole is formed on the second pressure-sensitive adhesive layer 33, the contact area between the heat-sensitive adhesive 31 and the second pressure-sensitive adhesive layer 33 is increased through the through hole, and when the user wants to remove the sticker from the attached surface, the sticker is heated, the heat-sensitive adhesive 31 loses adhesion, and thus the sticker is removed from the attached surface without leaving glue residues. Thus, the pressure-sensitive adhesive layer 3 can provide instant adhesion after being pasted, without waiting for the drying time, and can better adhere the substrate 2 and the adhesive layer 3. Meanwhile, the heat-sensitive adhesive 31 can be quickly solidified after being heated, providing fast adhesion. The heat-sensitive adhesive 31 can usually provide strong adhesion after being solidified. Meanwhile, the user can use the magnetic assembly 5 to remove the content of the sticker when the user does not want to remove the sticker by heating. The magnetic attraction layer 51 can take away the magnetic attraction matching layer 52 with the substrate 2 to remove the content of the sticker, replace the required sticker content, and conveniently remove and replace the new sticker. The magnetic sticker can be easily rolled up and stored.

[0036] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
