[0024] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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 in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0025] As Figure 1-2 shown, the easy-to-construct and apply car wrap tape in an embodiment of the present utility model sequentially includes a release film 1, a pressure-sensitive adhesive layer 2, a substrate layer 3, and a repair layer 4 from bottom to top. The release film 1 is adhered to the pressure-sensitive adhesive layer 2 to protect the pressure-sensitive adhesive layer 2, preventing dust and impurities from adhering to the pressure-sensitive adhesive layer 2 and affecting the later use effect. In addition, it is also convenient for winding the car wrap tape during production; the pressure-sensitive adhesive layer 2 is used to adhere to the paint surface, enabling the car wrap tape to firmly adhere to the paint surface and providing long-term protection for the paint; the substrate layer 3, as the substrate, enables the car wrap tape to have flexibility, stretchability, abrasion resistance, and chemical stability, etc., which can improve the easy constructability of the car wrap tape and extend the service life of the car wrap tape; the repair layer 4 enables the car wrap tape to be repaired after being scratched, thus ensuring the car wrap tape has a long-term use effect.
[0026] Furthermore, the thickness of the release film 1 can be 75μm, 80μm, 90μm, 100μm, 110μm, or 120μm. In this embodiment, the specific thickness of the release film is 75μm. The release film 1 sequentially includes a base layer 11, a coating layer 12, and a polysiloxane layer 13 from bottom to top, and the polysiloxane layer 13 is attached to the pressure-sensitive adhesive layer 2. The base layer 11 is a PP layer, and the coating layer 12 is a polyethylene layer. PP, namely polypropylene, has excellent mechanical strength and toughness, which can ensure the integrity of the release film 1 during peeling and prevent the release film 1 from being easily torn. The polyethylene layer has high chemical stability, good flexibility, and moderate peeling force, making the release film 1 easy to peel off and reducing the possibility of the release film 1 being contaminated and corroded during storage, thereby also ensuring the stability of the car wrap tape. The polysiloxane layer 13 has a low surface tension, which can reduce the adhesion force of the pressure-sensitive adhesive layer 2 to the release film 1, making the pressure-sensitive adhesive layer 2 and the release film 1 easy to separate and avoiding damage to the pressure-sensitive adhesive layer 2 when peeling off the release film 1.
[0027] The side of the coating layer 12 facing the polyorganosiloxane layer 13 is provided with protruding textures. The polyorganosiloxane layer 13 is matched and adhered to the protruding textures to form a receiving groove 14. The thickness of the polyorganosiloxane layer 13 is less than the height of the protruding textures to prevent the polyorganosiloxane layer 13 from filling the protruding textures. Correspondingly, a plurality of mutually connected air guide grooves 22 are provided on the side of the pressure-sensitive adhesive layer 2 facing away from the base material layer 3. The air guide grooves 22 extend to the side of the pressure-sensitive adhesive layer 2. A protruding portion 21 is formed between the plurality of air guide grooves 22. When the release film 1 is adhered to the pressure-sensitive adhesive layer 2, the protruding portion 21 is located in the receiving groove 14, and the protruding textures are located in the air guide grooves 22. When the pressure-sensitive adhesive layer 2 is applied to the car paint surface, the air guide grooves 22 play an exhaust role, which can reduce the appearance of bubbles, thereby improving the adhesion between the pressure-sensitive adhesive layer 2 and the car paint surface. During the application process, when it is necessary to repeatedly peel the pressure-sensitive adhesive layer 2 for positioning, the existence of the air guide grooves 22 is also conducive to peeling the pressure-sensitive adhesive layer 2 from the car paint surface. In addition, the mutual cooperation of the protruding portion 21 and the receiving groove 14 also increases the contact area between the release film 1 and the pressure-sensitive adhesive layer 2, improves the adhesion between the release film 1 and the pressure-sensitive adhesive layer 2, and plays a certain blocking role in the movement of the release film 1 on the surface of the pressure-sensitive adhesive layer 2, so that the release film 1 can be stably adhered to the surface of the pressure-sensitive adhesive layer 2 during transportation or storage.
[0028] Furthermore, the depth of the air guide grooves 22 can be 20μm, 25μm, 30μm, 35μm, 40μm, 45μm or 50μm, and the width of the air guide grooves 22 can be 30μm, 35μm or 40μm. In this embodiment, the depth of the air guide grooves 22 is specifically 30μm and the width is specifically 30μm. The appropriate width and depth are conducive to exhaust, and at the same time ensure that the pressure-sensitive adhesive layer 2 can be effectively adhered to the car paint surface. The width of the protruding portion 21 can be 100μm, 110μm, 120μm, 130μm, 140μm or 150μm. In this embodiment, the width of the protruding portion 21 is specifically 110μm.
[0029] The pressure-sensitive adhesive layer 2 is an acrylic adhesive layer, which can be firmly adhered to the car paint surface, and does not come off for a long time and leaves no residual glue when peeled off, protecting the paint surface from damage. The base material layer 3 is a TPU layer, which has excellent ductility, corrosion resistance and oxidation resistance, is conducive to stretching the car wrap tape for application, and enables the car wrap tape to have good use stability. The repair layer 4 is a thermoplastic polyurethane layer, which can be well restored after deformation and the external force is withdrawn, and high temperature can promote the restoration to speed up, so that the car wrap tape can provide long-term protection for the car paint. Selecting the pressure-sensitive adhesive layer 2, the base material layer 3 and the repair layer 4 made of the above materials to form the car wrap tape can effectively improve the use performance of the car wrap tape.
[0030] Further, the thickness will affect the use effect of the car wrap tape. The thickness of the pressure-sensitive adhesive layer 2 can be 40μm, 50μm, 60μm, 70μm or 80μm. In this embodiment, the thickness of the pressure-sensitive adhesive layer 2 is specifically 60μm. The thickness of the substrate layer 3 can be 145μm, 147μm, 150μm, 153μm or 155μm. In this embodiment, the thickness of the substrate layer 3 is specifically 150μm. The thickness of the repair layer 4 can be 10μm, 12μm, 14μm or 15μm. In this embodiment, the thickness of the repair layer 4 is specifically 12μm.
[0031] When the car wrap tape in the present utility model is applied to the surface of an automobile, the pressure-sensitive adhesive layer 2 can be closely attached to the surface of the automobile by means of the exhaust function of the air guide groove 22. And when repeated peeling is required during the positioning process, the existence of the air guide groove 22 makes the peeling easier to perform, and the overall application process is simple and easy to operate.
