Description

Technical Field

[0001] The utility model relates to an easy-to-tear reflective vehicle sticker, belonging to the technical field of reflective films. Background Art

[0002] Reflective vehicle body signs (or reflective car stickers) can improve the visibility of vehicles at night, especially when used on the body of small vehicles, which can effectively reduce rear-end collisions and collisions of large vehicles. In the automotive industry, reflective film materials are also widely used in products such as vehicle body signs and temporary parking signs to improve driving safety and visibility of signs. However, when reflective film is used as a reflective vehicle body sign, it is generally adhered to the paint surface of the vehicle body through a pressure-sensitive adhesive layer, and the existing vehicle body reflective signs usually include a reflective film layer, an acrylic resin layer on the reflective film layer and a pressure-sensitive adhesive layer (or adhesive layer) bonded together, and then a protective film layer is covered on the surface of the pressure-sensitive adhesive layer. When in use, the protective film layer is torn off and adhered to the paint surface of the vehicle body through the pressure-sensitive adhesive layer. As time goes by, we will replace or tear off the reflective logo. However, since the adhesion between the pressure-sensitive adhesive layer and the paint surface of the car body is stronger than the adhesion between the pressure-sensitive adhesive layer and the acrylic resin layer of the reflective film layer, there is a risk that the pressure-sensitive adhesive layer and the acrylic resin layer on the reflective film side will separate first when tearing off. At this time, we often cannot completely tear off the reflective logo. The pressure-sensitive adhesive layer is easy to tear and adhere to the paint surface of the car body. After the reflective logo is torn off, it is easy to leave residual glue on the surface of the car body, affecting the appearance and service life of the vehicle. Summary of the invention

[0003] The utility model aims to solve the above problems existing in the prior art and to provide an easy-to-tear reflective car sticker, so as to solve the problem that the existing car sticker is difficult to tear and easily adheres to the car body and paint surface.

[0004] The purpose of the utility model is achieved through the following technical solutions: an easy-to-tear reflective car sticker, the reflective car sticker comprises a reflective film and a pressure-sensitive adhesive layer for sticking on a vehicle body paint surface, the reflective film comprises an acrylic resin layer, and is characterized in that the reflective car sticker also comprises a transition layer, the reflective film is adhered to one side surface of the transition layer through the acrylic resin layer, and the other side surface of the transition layer is adhered to one side surface of the pressure-sensitive adhesive layer, the adhesion between the transition layer and the pressure-sensitive adhesive layer is greater than the adhesion between the pressure-sensitive adhesive layer and the vehicle body paint surface, and the adhesion between the transition layer and the acrylic resin layer is greater than the adhesion between the pressure-sensitive adhesive layer and the vehicle body paint surface.

[0005] The easy-to-tear reflective car sticker improves the structure of each film layer, adds a transition layer between the acrylic resin layer and the pressure-sensitive adhesive layer, and makes the adhesion between the transition layer and the pressure-sensitive adhesive layer and the acrylic resin layer of the reflective film greater than the adhesion between the pressure-sensitive adhesive layer and the vehicle body paint surface, which is equivalent to bonding the reflective film side to the pressure-sensitive adhesive layer through the transition layer, increasing the bonding affinity between the reflective film side and the pressure-sensitive adhesive layer as a whole, so that when it needs to be torn off after use, it can effectively ensure that the entire car sticker is torn off when the reflective car sticker is torn off, and the pressure-sensitive adhesive layer will not be partially torn and residual adhesive will not be left on the vehicle paint surface, which has the advantage of being easy to tear off. At the same time, the easy-to-tear reflective car sticker itself has a reflective film, which is made of a material with a reflective layer and has a good reflective effect. After use, it can also ensure that it can play a warning function at night or under low light conditions.

[0006] In the above-mentioned easy-to-tear reflective car sticker, the transition layer is a polyurethane adhesive layer or an epoxy resin adhesive layer. The polyurethane adhesive layer or the epoxy resin adhesive layer has excellent adhesion performance, and has good adhesion performance with both the acrylic resin layer and the pressure-sensitive adhesive layer. The adhesion between the polyurethane adhesive layer and the pressure-sensitive adhesive layer is greater than the adhesion between the pressure-sensitive adhesive layer and the vehicle body paint surface, thereby ensuring that when it is necessary to tear it off later, the pressure-sensitive adhesive layer adhered to the vehicle body paint surface side can be completely torn off, and no adhesive will remain on the vehicle body surface, thereby maintaining the aesthetics of the vehicle body. The polyurethane adhesive or the epoxy resin adhesive here are both made of existing materials. The pressure-sensitive adhesive layer generally uses acrylic pressure-sensitive adhesive, and the bonding strength between the pressure-sensitive adhesive layer and the polyurethane adhesive layer or the epoxy resin adhesive layer is higher than the bonding strength between the acrylic pressure-sensitive adhesive layer and the car body paint surface, and the bonding strength between the pressure-sensitive adhesive layer and the metal surface is also preferred. In this way, when replacing or removing, the pressure-sensitive adhesive layer can be more effectively and completely torn off without leaving residual adhesive on the car body paint surface, affecting the aesthetics of the car body paint surface. In addition, due to the higher bonding strength between the pressure-sensitive adhesive layer and the transition layer, it is also easier to tear off during the tearing process.

[0007] In the above-mentioned easy-to-tear reflective car sticker, the adhesion between the transition layer and the acrylic resin layer is greater than the adhesion between the transition layer and the pressure-sensitive adhesive layer, which can better ensure the adhesion between the entire reflective film and the transition layer, making the entire reflective film and the transition layer more firmly bonded, the overall stability is better, and it is also more conducive to the integrity when it is subsequently torn off.

[0008] In the above-mentioned easy-to-tear reflective car sticker, the thickness of the transition layer is greater than the thickness of the pressure-sensitive adhesive layer. By adjusting the thickness, the stability of adhesion on this side can be improved, and the easy-to-tear property during tearing can be better ensured, and the tearing can be more thorough.

[0009] In the above-mentioned easy-to-tear reflective car sticker, the reflective film also includes a surface layer and a micro-prism structure layer, the surface layer is adhered to one side surface of the micro-prism structure layer, and the other side surface of the micro-prism structure layer is adhered to the surface of the acrylic resin layer. The micro-prism structure is adopted in the reflective film, so that the whole has a high reflectivity effect. Of course, the reflective film here does not exclude other forms of reflective layer structures such as glass micro-bead layers.

[0010] In the above-mentioned easy-to-tear reflective car sticker, the surface of the pressure-sensitive adhesive layer away from the transition layer is also adhered with a release layer. The release layer protects the surface of the pressure-sensitive adhesive layer from being contaminated before use and ensures its adhesion. When in use, it is only necessary to tear off the release layer and then adhere the pressure-sensitive adhesive layer to the paint surface of the car body.

[0011] In the above-mentioned easy-to-tear reflective car sticker, the surface of the surface layer also has an anti-scratch layer, which can effectively prevent the surface of the reflective layer from being scratched and maintain the surface quality of the reflective film.

[0012] Compared with the prior art, this easy-to-tear reflective car sticker has the following advantages:

[0013] 1. By setting the transition layer, the adhesion between the transition layer and the pressure-sensitive adhesive layer and the adhesive layer is greater than the adhesion between the pressure-sensitive adhesive layer and the vehicle body paint surface, which can effectively ensure that the entire reflective vehicle sticker is torn off when it is torn off, without causing partial tearing of the pressure-sensitive adhesive layer and leaving residual adhesive on the vehicle paint surface, and has the advantage of being easy to tear off.

[0014] 2. By making the transition layer a polyurethane adhesive layer or an epoxy resin adhesive layer, it has excellent adhesion performance, which can better ensure that the pressure-sensitive adhesive layer adhered to the painted side of the car body will be completely torn off when it needs to be torn off later, and no adhesive will remain on the surface of the car body, thereby maintaining the aesthetics of the car body.

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] Combination Figure 1As shown, the easy-to-tear reflective sticker comprises a reflective film 1 and a pressure-sensitive adhesive layer 3 for sticking on a vehicle body paint surface, which may be a vehicle body paint surface of a truck or other vehicle, or a vehicle body paint surface of a tricycle or other vehicle. The reflective film 1 comprises an acrylic resin layer 11, and the pressure-sensitive adhesive layer 3 may be an acrylic pressure-sensitive adhesive. More importantly, the easy-to-tear reflective sticker also comprises a transition layer 2. During processing, the reflective film 1 is adhered to one side surface of the transition layer 2 through the acrylic resin layer 11, and the other side surface of the transition layer 2 is adhered to one side surface of the pressure-sensitive adhesive layer 3. When selecting materials, the adhesion between the transition layer 2 and the pressure-sensitive adhesive layer 3 is greater than the adhesion between the pressure-sensitive adhesive layer 3 and the vehicle body paint surface, and the adhesion between the transition layer 2 and the acrylic resin layer 11 is greater than the adhesion between the pressure-sensitive adhesive layer 3 and the vehicle body paint surface. This is equivalent to making targeted selection and design of the adhesion of the transition layer 2 so that the bonding affinity between the transition layer 2 and the acrylic resin layer 11 and the pressure-sensitive adhesive layer 3 adhered to its two sides is greater than the bonding affinity or adhesion between the pressure-sensitive adhesive layer 3 and the paint surface of the vehicle body. In this way, the bonding force between the pressure-sensitive adhesive layer 3 and the materials on the acrylic resin layer 11 side of the transition layer 2 and the reflective film 1 is greater, so that it is easier to tear off the reflective vehicle sticker as a whole when tearing it off, effectively avoiding the material of the pressure-sensitive adhesive layer 3 from sticking to the paint surface of the vehicle body, avoiding the defect of residual adhesive on the paint surface of the vehicle body, making it easy to tear off and more conducive to operation.

[0019] In a further embodiment, it is preferred that the above-mentioned transition layer 2 is a polyurethane adhesive layer or an epoxy resin adhesive layer. The material equivalent to the transition layer 2 is a known polyurethane adhesive material or epoxy resin adhesive material, and the corresponding transition layer 2 has the above-mentioned bonding properties, so that the adhesion between the transition layer 2 and the pressure-sensitive adhesive layer 3 side can be greater than the adhesion between the pressure-sensitive adhesive layer 3 and the paint surface of the vehicle body. When peeling off, the pressure-sensitive adhesive layer 3 can be pulled off from the paint surface of the vehicle body, making it easier to peel off and avoiding the problem of residual adhesive remaining on the paint surface of the vehicle body, thereby better ensuring the aesthetics of the vehicle body surface.

[0020] In a further embodiment, it is preferable that the adhesion between the transition layer 2 and the acrylic resin layer 11 is greater than the adhesion between the transition layer 2 and the pressure-sensitive adhesive layer 3. This can improve the overall adhesion of the reflective layer 1 side, which is more conducive to the integrity of the reflective layer after tearing off and has a certain degree of reusability. It is preferable that the thickness of the transition layer 2 is greater than the thickness of the pressure-sensitive adhesive layer 3, which is more convenient for subsequent tearability and stability.

[0021] In a further embodiment, the reflective film 1 further comprises a micro-prismatic structure layer 12 and a surface layer 13, wherein the surface layer 13 is adhered to one side surface of the micro-prismatic structure layer 12, and the other side surface of the micro-prismatic structure layer 12 is adhered to the surface of the acrylic resin layer 11. The reflective film with a micro-prismatic structure has the characteristic of high reflectivity, so that the easy-to-tear reflective film has high reflective performance. The surface layer 13 here can be made of polyurethane-modified acrylic material. As another alternative embodiment, the micro-prismatic structure layer 12 here can be a glass bead layer.

[0022] Furthermore, it is preferred that the surface of the pressure-sensitive adhesive layer 3 away from the transition layer 2 is also covered with a release layer 4. The release layer 4 is made of release paper. By pasting a layer of release layer 4, the adhesiveness of the pressure-sensitive adhesive layer 3 used for bonding the paint surface of the vehicle body can be better protected to prevent the surface adhesiveness from being affected by the pollution of the external environment. When in use, only the release layer 4 needs to be torn off. It is also preferred that the surface layer of the reflective film 1 also has a scratch layer 5. This prevents the surface from being scratched during use, improves the surface quality, and ensures the overall reflective effect.

[0023] When in use, the release layer 4 on the side of the pressure-sensitive adhesive layer 3 of the easy-to-tear reflective film is torn off, and then the easy-to-tear reflective film is pasted on the surface of the painted surface of the vehicle body of a truck or van through its pressure-sensitive adhesive layer 3 .

[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0025] Although the terms such as reflective film 1, acrylic resin layer 11, micro-prismatic structure layer 12, surface layer 13, transition layer 2, pressure-sensitive adhesive layer 3, release layer 4, anti-scratch layer 5 are frequently used in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
