Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum technology, and in particular to an electroplated aluminum with wear-resistant function. Background Technology

[0002] Electroplated aluminum foil, also known as hot stamping foil, is composed of a polyester film (PET) and multiple layers of chemical coatings applied to its surface. The polyester film is typically 12 micrometers thick. Some coatings are used to create a decorative effect, while others are used to control the properties of the hot stamping foil. Different coatings are suitable for different substrates. The aluminum layer is used to create a reflective effect. It is formed by melting and sublimating aluminum wire at high temperatures and then condensing it onto the hot stamping foil under ultra-low vacuum conditions. Existing electroplated aluminum foil does not have wear resistance. Therefore, an electroplated aluminum foil with wear resistance is used.

[0003] Existing technologies, such as patent CN215551491U, disclose an electroplated aluminum with wear-resistant and heat-insulating functions. This patent employs a base layer; uniformly spaced wear-resistant particles within the base layer; a first heat-insulating layer on the outside of the base layer; a color layer on the outside of the first heat-insulating layer; an electroplated layer on the outside of the color layer; a second heat-insulating layer on the outside of the electroplated layer; a potassium ion hardening layer on the outside of the second heat-insulating layer; a frosted layer on the outside of the potassium ion hardening layer; and a waterproof layer on the outside of the frosted layer. This invention enhances the overall wear resistance of the electroplated aluminum by incorporating wear-resistant particles within the base layer; it solves the problems of unreasonable structural design, poor heat insulation, inconvenience in use, and short service life of existing electroplated aluminum.

[0004] In daily work, during the use of the equipment, when it is subjected to frequent friction and scratches during long-term use after hot stamping, the equipment is prone to deformation and wear, resulting in a reduction in the service life of the items. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where items are easily worn and damaged frequently, and to propose an electroplated aluminum with wear-resistant properties.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electroplated aluminum with wear-resistant function, comprising a base layer, a release layer sprayed on the upper surface of the base layer, a first protective layer disposed at the upper end of the release layer, a particle filling layer disposed at the upper end of the first protective layer, a second protective layer disposed at the upper end of the particle filling layer, a color layer disposed at the upper end of the second protective layer, an electroplating layer disposed at the upper end of the color layer, and an adhesive layer disposed at the upper end of the electroplating layer.

[0007] Furthermore, the base layer is made of polyester film, which mainly serves to support the various coatings attached to it, facilitating continuous hot stamping during processing.

[0008] Furthermore, the release layer is made of silicone resin, and its main function is to allow the pigment, aluminum, and adhesive layer to quickly detach from the polyester film and be transferred and bonded to the surface of the object being hot-stamped after hot stamping.

[0009] Furthermore, the first protective layer is made of silicone, the particle filling layer is made of mineral debris, which refers to a loose mixture of sand and gravel, and its main function is to increase the wear resistance of the coating surface and make the coating more textured. The second protective layer is made of epoxy resin, which is a high molecular polymer with the molecular formula (C11H12O3)n. It refers to a class of polymers containing two or more epoxy groups in their molecules. Epoxy resin can bond with various materials, mainly to tightly bond the mineral debris to the color layer.

[0010] Furthermore, the color layer is made of synthetic resin and dye, and has two main functions: first, to display the color; and second, to protect the aluminum-plated pattern printed on the surface of the item from oxidation. The electroplating layer is made of aluminum-plated film, and its main function is to reflect light and change the color of the color layer to give it a metallic luster.

[0011] Furthermore, the adhesive layer is made of thermoplastic resin, and its main function is to bond the hot stamping material to the object being stamped.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting a first protective layer, a particle-filling layer, and a second protective layer, the equipment body can be effectively protected, improving its wear resistance. The first protective layer uses silicone, which is flexible and wear-resistant, providing excellent protection for the underlying base layer and peeling layer, resisting external friction and scratches. The particle-filling layer is filled with mineral debris, which further increases the surface roughness and hardness, dispersing external friction and effectively reducing overall wear. The second protective layer uses epoxy resin, which has high hardness and excellent wear resistance, adding another strong protective barrier to the internal layers, preventing external objects from directly contacting and abrading the innermost structure. By setting the first protective layer, the particle-filling layer, and the second protective layer, the wear resistance of the electroplated aluminum is greatly improved during long-term use. Even under complex working conditions such as frequent friction and scratches, it can still maintain a good appearance and performance, extending its service life. Attached Figure Description

[0016] Please see Figure 1 This utility model provides a technical solution: an electroplated aluminum with wear-resistant function, including a base layer 1, a release layer 2 sprayed on the upper surface of the base layer 1, a first protective layer 3 provided at the upper end of the release layer 2, a particle filling layer 4 provided at the upper end of the first protective layer 3, a second protective layer 5 provided at the upper end of the particle filling layer 4, a color layer 6 provided at the upper end of the second protective layer 5, an electroplating layer 7 provided at the upper end of the color layer 6, and an adhesive layer 8 provided at the upper end of the electroplating layer 7.

[0017] The following section will discuss the specific design and function of an electroplated aluminum alloy with wear-resistant properties.

[0018] In this implementation plan: the material of the base layer 1 is a polyester film. The polyester film is generally 12μm-25μm thick and can be stretched in both directions. Its main function is to support the coatings attached to it, which facilitates continuous hot stamping during processing. It has properties such as tensile strength and resistance to instantaneous high temperature.

[0019] Specifically, the release layer 2 is made of silicone resin, which is generally applied directly to the surface of the base layer 1. Its main function is to allow each coating to quickly detach from the polyester film and be transferred and bonded to the surface of the object to be hot-stamped after hot stamping. The release layer should have good peeling performance; otherwise, the hot-stamped graphics will be blurry, uneven, and affect the quality of the hot-stamped product.

[0020] Specifically, the first protective layer 3 is made of silicone. Silicone is an organosilicon compound, which refers to a compound containing Si-C bonds and at least one organic group directly connected to a silicon atom. Compounds that connect organic groups to silicon atoms through oxygen, sulfur, nitrogen, etc., are also commonly considered organosilicon compounds. Its main functions are drying, moisture prevention, and rust prevention, preventing subsequent coatings from becoming damp and peeling off. It also has transparency, not hindering the reflection of the electroplated layer 7. The particle-filling layer 4 is made of mineral debris, a loose mixture of sand and gravel. Its main function is to increase the wear resistance of the coating surface, making the coating more textured. The second protective layer 5 is made of epoxy resin, a high-molecular polymer with the molecular formula (C11H12O3)n. Epoxy resin is a general term for polymers containing two or more epoxy groups in their molecules. Epoxy resin can bond with various materials, mainly tightly binding the mineral debris to the color layer 6.

[0021] Specifically, the materials for color layer 6 are synthetic resins and dyes. Commonly used resins include polyurethane nitrocellulose, melamine-formaldehyde resin, and modified rosin. During production, the resin and dye are dissolved in an organic solvent to form a color paste, which is then coated and dried. Its main function is to display the color and protect the aluminum-plated image printed on the surface of the item from oxidation. The color of color layer 6 is given a gloss after passing through the aluminum-plated layer, and the color has a certain variation. The coating of color layer 6 requires a fine coating without any small particles to avoid pinholes and uniform coating. The material for electroplating layer 7 is an aluminum-plated film. The aluminum-plated film is made by placing a film coated with colorant in the vacuum chamber of a vacuum continuous aluminum plating machine. Under a certain vacuum degree, aluminum wire is melted and continuously evaporated onto the color layer of the film through resistance heating, thus forming the aluminum-plated layer. The main function of the aluminum-plated layer is to reflect light and change the color of color layer 6 to give it a metallic luster.

[0022] Specifically, the material of adhesive layer 8 is thermoplastic resin. Thermoplastic resin has the properties of softening when heated and hardening when cooled, and it does not undergo chemical reactions. No matter how many times heating and cooling are repeated, it can maintain this property. Thermoplastic resin has good toughness, large damage tolerance, good dielectric constant, and its storage period is not limited. It does not require low-temperature storage and does not require large special equipment such as autoclaves for molding. In particular, it has good recyclability, recyclability, reusability and environmental protection characteristics. The resin is dissolved in an organic solvent or prepared into an aqueous solution, coated on the aluminum layer by a coating machine, and dried to form adhesive layer 8. Its main function is to bond the hot stamping material to the object to be stamped.

[0023] Working Principle: By setting up a first protective layer 3, a particle-filled layer 4, and a second protective layer 5, the equipment body can be effectively protected, improving its wear resistance. The first protective layer 3 uses silicone, which is flexible and wear-resistant, and can provide good protection for the underlying base layer 1 and the peeling layer 2, resisting external friction and scratches. The particle-filled layer 4 is filled with mineral debris, which can further increase the surface roughness and hardness, disperse the friction force applied by the outside world, and effectively reduce the overall wear. The second protective layer 5 is made of epoxy resin, which has high hardness and good wear resistance, adding another strong protective barrier to the internal layers, preventing external objects from directly contacting and wearing down the inner structure. By setting up the first protective layer 3, the particle-filled layer 4, and the second protective layer 5, the wear resistance of the electroplated aluminum is greatly improved during long-term use. Even under complex working conditions such as frequent friction and scratches, it can still maintain a good appearance and performance, extending its service life.
