Description

Technical Field

[0001] The utility model discloses an anti-deformation reflective lettering film, belonging to the field of thin films. Background Art

[0002] Lettering film is a kind of retro-reflective material that has been made into a film and can be directly used. It is made using glass bead technology, micro-prism technology, synthetic resin technology, thin film technology, coating technology and micro-replication technology. Reflective lettering film is a kind of reflective lettering film, which is often used to print on clothing as decoration.

[0003] The lettering film patterns printed on clothing are often folded during the storage process. If the crease is located at the pattern position, the lettering film pattern will also bend and crack over time, eventually causing the pattern to fade or fall off.

[0004] In view of the above problems, a new improvement plan is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-deformation reflective lettering film in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a deformation-resistant reflective lettering film, which includes a protective layer, a pattern layer, an anti-bending layer and a hot-melt adhesive layer from the outside to the inside. The anti-bending layer includes an anti-bending part and an adhesive layer wrapping the anti-bending part, and the anti-bending part extends along the length direction of the pattern layer.

[0007] Preferably, the anti-bending member has a wavy cross-section.

[0008] Preferably, an anti-deformation layer is further provided between the anti-bending layer and the hot-melt adhesive layer, and the anti-deformation layer comprises a plurality of first anti-deformation blocks and second anti-deformation blocks abutting against each other, and the first anti-deformation blocks and the second anti-deformation blocks are wrapped with an adhesive layer.

[0009] Preferably, one side where the first anti-deformation block and the second anti-deformation block abut against each other is arc-shaped.

[0010] Preferably, the first anti-deformation block and the second anti-deformation block extend along the width direction of the pattern layer.

[0011] Preferably, a plurality of protrusions are formed on a side of the protection layer away from the pattern layer.

[0012] Preferably, micro-ridges are embedded in the protrusions.

[0013] Preferably, the anti-bending member, the first anti-deformation block and the second anti-deformation block are all made of silicone.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting an anti-bending layer extending along the length direction of the pattern layer, and providing a wavy anti-bending part in the anti-bending layer, when subjected to bending force, the anti-bending part can offset most of the load, thereby ensuring that the pattern layer will not be damaged by excessive bending.

[0016] 2. An anti-deformation layer extending along the width direction of the pattern layer is provided. The first anti-deformation block and the second anti-deformation block in the anti-deformation layer can offset part of the load when the lettering film is subjected to bending force in another direction, and cooperate with the anti-bending layer to withstand bending deformation in different directions.

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1As shown, an anti-deformation reflective lettering film comprises, from outside to inside, a protective layer 1, a pattern layer 2, an anti-bending layer 3 and a hot-melt adhesive layer 4. The protective layer 1 can be made of a transparent material to protect the pattern layer 2 from being scratched without affecting the viewing of the pattern layer 2. The hot-melt adhesive layer 4 is used to be bonded to clothing during the thermal transfer process. The anti-bending layer 3 comprises an anti-bending member 5 and an adhesive layer wrapping the anti-bending member 5. The adhesive layer is used to be bonded to the adjacent layer. The anti-bending member 5 extends along the length direction of the pattern layer 2. The anti-bending layer 3 is used to withstand the bending force on the clothing area printed with the pattern, so as to provide a better bearing capacity for the pattern and prevent it from being excessively deformed and damaged. Since the cross-section of the anti-bending member 5 is wavy, in the field of construction, the material with a wavy cross-section has a stronger ability to bear loads. Under the same load, the deformation of the material with a wavy cross-section is the smallest. Therefore, the anti-bending member 5 with a wavy cross-section can well protect the pattern layer 2 from being damaged by bending when the lettering film is about to bend and deform in the length direction.

[0022] An anti-deformation layer 6 is also provided between the anti-bending layer 3 and the hot melt adhesive layer 4. The anti-deformation layer 6 includes a plurality of first anti-deformation blocks 7 and second anti-deformation blocks 8 abutting against each other. The first anti-deformation blocks 7 and the second anti-deformation blocks 8 are wrapped with an adhesive layer, which is used to glue the adjacent layers. The anti-deformation blocks abutting against each other can squeeze each other when subjected to a bending load, providing a higher reaction force to bear the load. Figure 1 It can be seen that the cross-sections of the first anti-deformation block 7 and the second anti-deformation block 8 are both triangular, and by utilizing the stability of the triangle, they can withstand a greater bending load.

[0023] At the same time, the side where the first anti-deformation block 7 and the second anti-deformation block 8 abut against each other is arc-shaped. When subjected to a force that causes the lettering film to bend, the side where the first anti-deformation block 7 and the second anti-deformation block 8 abut against each other will squeeze each other, and the arc-shaped contact surface can reduce the stress generated during squeezing, thereby preventing premature failure. The first anti-deformation block 7 and the second anti-deformation block 8 extend along the width direction of the pattern layer 2. This design allows the lettering film to withstand a larger bending load by utilizing the triangular cross-section of the anti-deformation block when the lettering film is about to bend and deform in the width direction, thereby preventing the lettering film from being damaged due to excessive bending.

[0024] The protective layer 1 of the product is formed with a plurality of protrusions 9 on one side away from the pattern layer 2. The protrusions 9 can improve the friction resistance of the surface of the product and prevent the pattern from being scratched during daily use. Figure 2 As shown, micro-prisms 10 are embedded in the protrusions 9. The micro-prisms 10 can refract in different directions when sunlight shines on the surface of the engraving film, making the surface of the product look more colorful.

[0025] Finally, the anti-bending part 5, the first anti-deformation block 7 and the second anti-deformation block 8 are all made of silicone. The silicone material has good elasticity and recovery ability. When the anti-bending part 5, the first anti-deformation block 7 and the second anti-deformation block 8 are subjected to bending load, they can recover quickly.
