Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of label stickers, and more specifically, to a flame-retardant label. Background Art
[0002] Currently, labels on the market, especially those used to identify electronic devices, cables, electrical products, or flammable items, often lack flame-retardant properties. In the event of a fire or in a high-temperature environment, these labels may burn rapidly, not only intensifying the fire but also potentially causing information loss, making rescue and investigation work difficult.
[0003] Existing flame-retardant labels mainly include an adhesive layer, a printing layer, and a flame-retardant layer arranged in sequence from bottom to top. In the event of a fire or in a high-temperature environment, only the outer surface of the printing layer can be protected from fire. However, due to the high temperature of the device or cable itself or during combustion, it is very likely that the printing layer will be damaged by burning from the side of the adhesive layer, and comprehensive protection of the printing layer cannot be achieved.
[0004] Therefore, a new solution is needed to solve this problem. Summary of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a flame-retardant label that can protect the printing layer from fire in a high-temperature or fire environment and prevent the information on the printing layer from being damaged.
[0006] The above technical objective of the utility model is achieved through the following technical solutions: A flame-retardant label includes a release layer, an adhesive layer, and a printing layer, and further includes a flame-retardant frame, a first flame-retardant layer arranged on the lower surface of the flame-retardant frame, and a second flame-retardant layer arranged on the upper surface of the flame-retardant frame. A sealed cavity is formed between the first flame-retardant layer, the flame-retardant frame, and the second flame-retardant layer. The printing layer is arranged in the sealed cavity. The adhesive layer is arranged on the lower surface of the first flame-retardant layer. The release layer is arranged on the lower surface of the adhesive layer. The second flame-retardant layer can penetrate the printing layer.
[0007] In one of the embodiments, the first flame-retardant layer and the second flame-retardant layer are respectively provided with welding indentations facing the flame-retardant frame, and the welding indentations are spaced at intervals along the perimeter of the flame-retardant frame to form several.
[0008] In one embodiment, the flame-retardant frame includes an upper flame-retardant layer and a lower flame-retardant layer. The upper flame-retardant layer and the lower flame-retardant layer located outside the flame-retardant frame are bonded by a first adhesive layer, and the upper flame-retardant layer and the lower flame-retardant layer located inside the flame-retardant frame are bonded by a second adhesive layer. The melting point of the second adhesive layer is lower than that of the first adhesive layer. A powder flame retardant storage cavity is formed by enclosing the upper flame-retardant layer, the lower flame-retardant layer, the first adhesive layer, and the second adhesive layer. The second adhesive layer melts at a specific temperature, causing the inner side of the flame-retardant frame to open towards the printing layer.
[0009] In one embodiment, the adhesive layer is an adhesive layer.
[0010] In one embodiment, the second flame-retardant layer is a transparent flame-retardant PVC film.
[0011] In summary, the present utility model has the following beneficial effects: Through the arrangement of the first flame-retardant layer, the flame-retardant frame, and the second flame-retardant layer, the printing layer can be completely enclosed in a closed cavity, so as to provide flame-retardant protection for the printing layer in a high-temperature or fire environment and protect the information of the printing layer from being damaged.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Such as Figures 1 to 3As shown in the figure, an embodiment of the present application provides a flame-retardant label, which includes a release layer 1, an adhesive layer 2, and a printing layer 6. It further includes a flame-retardant frame 4, a first flame-retardant layer 3 adhered to the lower surface of the flame-retardant frame 4, and a second flame-retardant layer 5 adhered to the upper surface of the flame-retardant frame 4. A sealed cavity is formed among the first flame-retardant layer 3, the flame-retardant frame 4, and the second flame-retardant layer 5. The printing layer 6 is arranged in the sealed cavity. The adhesive layer 2 is adhered to the lower surface of the first flame-retardant layer 3, and the release layer 1 is arranged on the lower surface of the adhesive layer 2. The second flame-retardant layer 5 can see through the printing layer 6 to ensure the readability of information.
[0018] In the above manner, through the arrangement of the first flame-retardant layer 3, the flame-retardant frame 4, and the second flame-retardant layer 5, the printing layer 6 can be completely covered in the sealed cavity, so that the printing layer 6 can be flame-retardant protected in a high-temperature or fire environment, and the information of the printing layer 6 can be protected from being damaged.
[0019] In this embodiment, the first flame-retardant layer 3 and the second flame-retardant layer 5 are respectively provided with welding indentations facing the flame-retardant frame 4, and the welding indentations are arranged at intervals around the flame-retardant frame 4 for several. Specifically, the welding indentations can be formed by hot pressing welding or ultrasonic welding.
[0020] In the above manner, the setting of the welding indentations significantly enhances the connection strength among the first flame-retardant layer 3, the flame-retardant frame 4, and the second flame-retardant layer 5. In a high-temperature or fire environment, this enhanced connection can effectively prevent the separation between the first flame-retardant layer 3, the second flame-retardant layer 5, and the flame-retardant frame 4, so as to maintain the integrity and flame-retardant performance of the flame-retardant label. At the same time, in a high-temperature environment, the flame-retardant label may be deformed due to thermal expansion. The setting of the welding indentations can limit the deformation of the first flame-retardant layer 3, the flame-retardant frame 4, and the second flame-retardant layer 5 to a certain extent, and maintain the flatness and shape stability of the flame-retardant label.
[0021] In this embodiment, the flame-retardant frame 4 includes an upper flame-retardant layer 41 and a lower flame-retardant layer 42. The upper flame-retardant layer 41 and the lower flame-retardant layer 42 located outside the flame-retardant frame 4 are bonded by a first adhesive layer 43, and the upper flame-retardant layer 41 and the lower flame-retardant layer 42 located inside the flame-retardant frame 4 are bonded by a second adhesive layer 44. The flame-retardant frame 4 is specifically made of a flame-retardant PVC material layer with a certain thickness, so that the flame-retardant label as a whole has a certain toughness. The melting point of the second adhesive layer 44 is lower than that of the first adhesive layer 43. A powder flame retardant storage cavity is formed by enclosing the upper flame-retardant layer 41, the lower flame-retardant layer 42, the first adhesive layer 43, and the second adhesive layer 44. The second adhesive layer 44 melts at a specific temperature, causing the inner side of the flame-retardant frame 4 to open towards the printing layer 6. The specific materials of the first adhesive layer 43 and the second adhesive layer 44 are not limited, as long as the first adhesive layer 43 can withstand a relatively high temperature in case of fire or high temperature, and the second adhesive layer 44 can melt at a specific temperature. The specific temperature here is the lowest temperature in case of fire or high temperature.
[0022] In the above manner, the powder flame retardant stored in the powder flame retardant storage cavity can provide an additional flame-retardant effect at a critical moment. When encountering high temperature or fire, the second adhesive layer 44 melts, and the powder flame retardant is released towards the printing layer 6, which can effectively inhibit the spread of fire, thereby protecting the printing layer 6 and the surrounding structures.
[0023] In this embodiment, the adhesive layer 2 is an adhesive layer. The adhesive layer has self-adhesion, and can achieve fast and convenient pasting operations without the need to use additional glue.
[0024] In this embodiment, the second flame-retardant layer 5 is a transparent flame-retardant PVC film. The transparent flame-retardant PVC film has excellent flame-retardant performance, can effectively prevent the spread of fire, and at the same time can maintain a high transparency to ensure that light can pass through without affecting the visual effect.
[0025] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
