Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold ironing film, specifically an anti-lifting cold ironing film. Background Technology
[0002] In existing cold foil technology, traditional cold foil often faces the following problems during the application process:
[0003] 1. Prominent edge lifting problem: Due to insufficient adhesive structure design, the adhesion between the UV adhesive layer and the surface of the object being adhered to is limited. Especially in the edge area, it is easily affected by external forces or environmental factors and lifts up, causing the cold heat film to fall off and affecting the decorative or protective effect.
[0004] 2. Insufficient positioning accuracy: The lack of an effective positioning structure makes it difficult to accurately align the target position during pasting, which may lead to pattern offset or uneven edges, reducing the product's aesthetics and user experience.
[0005] 3. Limited application scenarios: For special material surfaces such as metal, traditional cold foil only relies on adhesive bonding, which has limited fixing effect, and the decorative layer design is simple and cannot meet diverse aesthetic needs (such as reflective, magnetic and other functions); therefore, an anti-lifting cold foil is proposed to address the above problems.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0028] This application discloses an anti-lifting cold ironing film. (See also...) Figures 1 to 4 A cold-pressing film for preventing curling includes a base film layer 1. The lower surface of the base film layer 1 is sequentially provided with a release layer 2, a transparent protective layer 3, an imaging layer 4, a pattern base layer 5, and a positioning film layer 6. The lower surface of the positioning film layer 6 is provided with a metal positioning frame layer 7, and the lower surface of the metal positioning frame layer 7 is provided with a UV adhesive layer 8.
[0029] The base film layer 1 is a PET film. The release layer 2 is formed by coating the lower surface of the base film layer 1 with an organosilicon release agent. The transparent protective layer 3 is attached to the lower surface of the release layer 2. The imaging layer 4 is bonded to the lower surface of the transparent protective layer 3. The pattern base layer 5 is fixed to the lower surface of the imaging layer 4. The positioning film layer 6 is bonded to the lower surface of the pattern base layer 5.
[0030] Preferably, the base film layer 1 is prepared by using PET material and processing it into a base film layer 1 with a thickness between 0.01 and 0.1 mm according to actual needs. PET material has good strength and flexibility, which can provide stable basic support for cold stamping film.
[0031] Preferably, the release layer 2 is coated by uniformly coating an organosilicon release agent on the lower surface of the base film layer 1 to form a release layer 2 with a thickness of 0.001-0.01mm. The coating process can be carried out using equipment such as a coating machine to ensure that the release agent is evenly distributed so that the release paper can be easily peeled off later.
[0032] Preferably, the transparent protective layer 3 is laminated: a PE film is used as the transparent protective layer 3, the thickness of which is controlled between 0.005-0.05mm. The transparent protective layer 3 is laminated to the lower surface of the release layer 2 by hot pressing or bonding, so as to protect the underlying structure.
[0033] Preferably, the pattern base layer 5 is made by printing various patterns on paper or plastic film according to actual design requirements to make a pattern base layer 5 with a thickness of 0.01-0.05mm, and then fixing the pattern base layer 5 to the lower surface of the imaging layer 4.
[0034] Preferably, the positioning film layer 6 is bonded: a thin film with a certain degree of adhesion is selected as the positioning film layer 6, and its thickness is 0.005-0.02mm. The positioning film layer 6 is bonded to the lower surface of the pattern base layer 5.
[0035] The imaging layer 4 includes an aluminum foil layer 401. The top of the aluminum foil layer 401 has multiple placement cavities 402. A magnetic sheet 403 is embedded in each placement cavity 402. Multiple grooves 404 are pressed at equal intervals on the top of the aluminum foil layer 401. A protrusion 405 is formed between the multiple grooves 404. The grooves 404 are filled with a glitter layer 406.
[0036] Preferably, the imaging layer 4 is fabricated as follows: First, an aluminum foil layer 401 is prepared. The aluminum foil is processed into a thin sheet with a thickness of 0.002-0.02 mm. Several placement cavities 402 are formed in the aluminum foil layer 401 through processes such as stamping. A magnetic sheet 403 is placed in the placement cavity 402, and the outer surface of the magnetic sheet 403 is bonded to the inner wall of the placement cavity 402 using glue. Multiple protrusions 405 and grooves 404 are pressed into the upper surface of the aluminum foil layer 401 using a mold. A glitter layer 406 is filled and bonded to the grooves 404. The thickness of the glitter layer 406 is 0.001-0.005 mm to increase the decorative effect of the imaging layer 4. The fabricated imaging layer 4 is fixed to the lower surface of the transparent protective layer 3 by hot pressing or bonding.
[0037] The metal positioning frame layer 7 includes a metal positioning frame 701, on which a plurality of through holes 702 are provided. A positioning mesh 703 is embedded in the through holes 702. The UV adhesive layer 8 is aligned with the position of the positioning mesh 703 and partially penetrates into the mesh of the positioning mesh 703.
[0038] Preferably, the metal positioning frame 701 and the positioning mesh 703 are installed as follows: The metal positioning frame 701 is made of aluminum alloy material by stamping, with a frame width of 0.5-2mm. Through holes 702 are machined in the metal positioning frame 701. The metal mesh or plastic mesh is used as the positioning mesh 703, with a mesh diameter of 0.1-1mm. The positioning mesh 8 is embedded in the through holes 702 and bonded to the inner wall surface. Then, the metal positioning frame 701 with the positioning mesh 703 is fixed to the lower surface of the positioning film layer 6.
[0039] Working principle: In use, peel the cold foil from the release paper and attach the side with the UV adhesive layer 8 to the surface of the object to be decorated or protected. Position the edges of the cold foil using the metal positioning frame 701 to ensure accurate adhesion to the target location. At this point, the localized adhesive layer 8 aligned with the positioning mesh 703 will penetrate into the mesh openings of the positioning mesh 703 under pressure, forming a strong connection.
[0040] When the object is made of iron, the magnetic sheet 403 in the imaging layer 4 will magnetically attract the iron object, further enhancing the adhesion between the cold foil and the object. Then, by irradiating with ultraviolet light, the UV adhesive layer 8 is cured, thus firmly adhering the cold foil to the surface of the object, achieving both decorative and protective functions.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
