Description

Technical Field

[0001] The utility model relates to the technical field of electrochemical aluminum, in particular to temperature-changing electrochemical aluminum. Background Art

[0002] Hot stamping paper, commonly known as electroplated aluminum in northern my country, consists of a polyester film (PET) coated with multiple layers of chemical coatings. The polyester film is typically 12 microns thick. Some of the coatings create a decorative effect, while others control the properties of the hot stamping paper. Different coatings are suitable for different substrates. The aluminum layer creates a reflective effect. It is formed by melting aluminum filaments at high temperatures, sublimating them, and then condensing them onto the hot stamping paper under ultra-low vacuum conditions.

[0003] Anodized aluminum uses an aluminum layer to reflect the internal color-changing material, thereby enhancing the reflective effect. However, the reflective layer lacks a protective structure and is easily corroded and damaged, which in turn affects the reflective effect of the color-changing material and is inconvenient for actual use. Utility Model Content

[0004] The purpose of the utility model is to provide a temperature-changing electrochromic aluminum to solve the problem that the reflective layer in the prior art lacks a protective structure, is easily damaged by corrosion, and thus affects the reflective effect of the color-changing material and is inconvenient for actual use.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A temperature-changing electrochemical aluminum comprises a base layer, a waterproof layer is provided at the bottom of the base layer, a thermochromic layer is provided on the top of the base layer, a reflective layer is provided on the top of the thermochromic layer, a wear-resistant layer is provided on the top of the reflective layer, and a protective layer is further provided between the reflective layer and the wear-resistant layer.

[0007] Preferably, the waterproof layer is made of PVC film to prevent water penetration and the failure of the internal coating.

[0008] Preferably, the base layer is made of polyester film to support the various coatings attached to its surface.

[0009] Preferably, the thermochromic layer uses thermochromic ink.

[0010] Preferably, the reflective layer is formed by aluminum electroplating and evaporation to form an aluminum layer with a reflective effect.

[0011] Preferably, the protective layer adopts an antioxidant film, which has an antioxidant effect, thereby preventing the aluminum layer from being corroded. The wear-resistant layer adopts a transparent wear-resistant coating, thereby protecting the antioxidant film and further protecting the reflective layer.

[0012] The utility model has at least the following beneficial effects:

[0013] By setting PVC film as the waterproof layer of the base layer, it can prevent water penetration and cause failure of the internal coating. By setting anti-oxidation film and transparent wear-resistant coating, it can play an antioxidant and wear-resistant role without affecting the reflective effect of the reflective layer, thereby protecting the reflective layer from damage and keeping the basic performance of the entire electrochemical aluminum relatively stable.
