Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping, in particular to hot stamping anti-oxidation electrochemical aluminum. Background Art

[0002] Hot stamping paper is commonly known as electroplated aluminum in northern my country. It is composed of polyester film (PET) and multiple layers of chemical coatings coated on its surface. The polyester film is usually 12 microns thick, and some of the coatings are used to produce decorative effects, while some coatings are used to control the performance of hot stamping paper. Different coatings are suitable for different substrates. After searching, the Chinese patent publication number CN217705245U discloses a hot stamping anti-oxidation type electroplated aluminum hot stamping foil, including a hot stamping foil body, a strengthening mechanism and a paper tube, and the hot stamping foil body is wrapped on the surface of the paper tube. By connecting the anti-magnetic attraction coating and the sealing film on the side of the electroplated aluminum layer, the influence of magnetic force on the hot stamping foil is reduced, which is not conducive to its connection and use, and the sealing film is used for sealing and isolation, and the high temperature resistant layer and the anti-oxidation layer are connected on the side of the electroplated aluminum layer to reduce the deformation of the hot stamping foil during the hot stamping process and ensure the anti-oxidation effect of the hot stamping foil.

[0003] In the above technical solution, the high temperature resistant layer and the anti-oxidation layer are connected to the side of the electroplated aluminum layer, which reduces the deformation of the hot stamping foil during the hot stamping process and ensures the anti-oxidation effect of the hot stamping foil. However, there is no side protection, and air can easily enter the interior of the electroplated aluminum from the side, and the air penetration path cannot be increased to slow down the internal oxidation rate, thereby affecting the service life.
