Description

Technical Field

[0001] This utility model relates to the field of metal decoration and handicrafts technology, specifically to a copper plate image panel that combines micro-polishing and brushing with relief carving. Background Technology

[0002] Copperplate engraving is widely used in the decorative field due to its metallic texture and durability. Currently, the main techniques used in copperplate engraving include engraving (intaglio) and hammering relief. Engraving involves carving recessed lines into a colored copper plate. This technique has the following drawbacks: First, the exposed copper material on the inner wall of the engraved lines is prone to oxidation and discoloration, affecting long-term stability; second, the artistic expression is limited, making it difficult to achieve complex three-dimensional patterns. Hammering relief involves hammering a three-dimensional relief onto a thin copper plate using a mold, followed by chemical aging. The drawbacks of this technique are: reliance on molds, making personalized and small-batch production impossible; difficulty in expressing rich colors; and the thin copper plate has low structural strength and is easily deformed.

[0003] In the prior art, such as the patent document "CN216373636U" which discloses a "random-patterned brushed copper plate", the focus is on solving the interlayer cracking problem of multi-layer composite boards by inserting posts and adhesive layers. Its surface texture is only a simple decorative layer and does not address the core issue of how to combine the brushed metal texture with the full-color three-dimensional relief pattern in a long-term and stable manner. In addition, traditional copper plate painting mounting mostly uses permanent adhesives or mechanical fixation, which is not conducive to the later maintenance and reuse of the painting core.

[0004] Therefore, there is an urgent need for a new type of copper plate image board that can integrate the original texture of metal, rich colors, three-dimensional relief effect, and has excellent anti-oxidation properties and convenient and reversible mounting structure. Utility Model Content

[0005] This utility model aims to overcome the shortcomings of the existing technology and provide a copper plate picture panel that combines micro-polished brushed and embossed designs. This panel not only presents the artistic effect of a perfect combination of metallic brushed texture and colorful three-dimensional embossing, but also achieves long-term anti-oxidation protection through a unique layered structure and is equipped with a reversible and non-destructive mounting structure, which is convenient for long-term preservation and maintenance.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] A copper plate image panel combining micro-polished brushed and embossed designs includes a copper plate body. The copper plate body comprises a brass substrate layer and a micro-polished brushed texture layer. The micro-polished brushed texture layer is formed on the upper surface of the brass substrate layer. A fluorocarbon anti-oxidation bonding layer is coated and cured on the micro-polished brushed texture layer. A UV-cured embossed pattern layer is formed on the fluorocarbon anti-oxidation bonding layer by digital printing. The UV-cured embossed pattern layer is made of transparent or semi-transparent material and forms a raised pattern. A UV-cured colored pattern layer is formed on the fluorocarbon anti-oxidation bonding layer by digital printing and is located in the uncovered area of ​​the UV-cured embossed pattern layer.

[0008] Furthermore, the UV-cured embossed pattern layer and the UV-cured colored pattern layer are layer structures formed by printing in stages and at least partially do not overlap in the thickness direction.

[0009] Furthermore, the thickness of the UV-cured embossed pattern layer is 0.3-0.5 mm, and its outer surface has a micro-frosted texture.

[0010] Furthermore, the fluorocarbon antioxidant bonding layer is a nano-fluorocarbon ink layer with a thickness of 70-90 μm.

[0011] Furthermore, it also includes an outer protective color-fixing layer covering the UV-cured embossed pattern layer and the UV-cured colored pattern layer.

[0012] Furthermore, it also includes a mounting assembly, which includes a back panel, wherein the lower surface of the brass substrate layer is bonded and fixed to the back panel by a removable double-sided adhesive layer.

[0013] Furthermore, the removable double-sided adhesive layer is made of PET material with a thickness of 0.15-0.20mm.

[0014] Furthermore, the removable double-sided adhesive layer is fully distributed between the lower surface of the brass plate substrate layer and the back plate.

[0015] Furthermore, the thickness of the brass plate substrate layer is 0.5-0.8 mm.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model retains the warm metallic luster and delicate touch of brass by using a micro-polished brushed texture layer. A transparent UV-cured embossed pattern layer forms a three-dimensional protrusion on top of it, and the micro-frosted texture and the brushed texture below produce a soft light diffusion, creating a strong sense of layering. The UV-cured colored pattern layer provides rich colors. The combination of the three achieves a unique artistic effect of "metallic texture, three-dimensional shape, and brilliant colors". At the same time, the fluorocarbon anti-oxidation bonding layer serves as a key intermediate layer, which not only firmly bonds the upper and lower layers, but more importantly, provides an excellent anti-oxidation barrier for the copper base. Combined with the outer protective color fixing layer, a double protection system is formed, which significantly extends the service life of the artwork.

[0018] 2. This utility model uses digital UV printing technology to produce relief and color in steps, eliminating the need for physical molds. It enables personalized, small-batch, and rapid production of complex patterns. The separation of the relief and color layers ensures their optimal performance. Furthermore, removable PET double-sided adhesive of specific thickness and performance is used for full back-side pasting, combining the thin copper plate with the heavy back plate into a rigid whole, completely eliminating warping and deformation of the image. At the same time, this mounting method is reversible and damage-free, greatly facilitating the transportation, preservation, maintenance, and reuse of the artwork, embodying the concepts of environmental protection and practicality.

[0019] Finally, through optimized composite structure and mounting methods, thinner copper plates can be used to achieve the required flatness and strength, saving precious copper materials and reducing product costs. Attached Figure Description

[0029] Example 1

[0030] exist Figures 1-3 In this invention, a technical solution is provided: a copper plate image panel combining micro-polished brushing and relief engraving, including a copper plate body 100 as the core part of the copper plate image panel. It is a multi-layer composite functional structure. Specifically, the copper plate body 100 includes a brass plate substrate layer 1 as a supporting base. The brass plate substrate layer 1 is made of H62 brass plate with a thickness of 0.5-0.8mm, for example, 0.6mm. This thickness ensures sufficient support while saving materials and reducing the overall weight.

[0031] Secondly, on the upper surface of the brass plate substrate layer 1, a micro-polished brushed texture layer 2 is formed through mechanical processing. The preparation process is as follows: first, the surface of the brass plate is cleaned and degreased, and then a flat wire drawing machine equipped with 150-180 mesh nylon wire drawing wheels is used for unidirectional wire drawing to form a uniform and delicate straight wire texture. Subsequently, a scouring pad wheel or wool wheel with a higher mesh (such as 400-600 mesh) is used to gently micro-polish the brushed surface. This process not only removes the fine burrs that may be generated during wire drawing, but also makes the metal surface present a warm and soft luster, rather than a dazzling mirror reflection, laying the foundation for a high-end artistic texture.

[0032] Then, a fluorocarbon anti-oxidation bonding layer 3 is coated and cured on the micro-polished brushed texture layer 2. This layer is composed of environmentally friendly nano-fluorocarbon ink. During construction, 1%-5% of a special curing agent can be added to the ink and stirred evenly. Spraying or roller coating is used to evenly cover the brushed surface. Subsequently, the coated copper plate is placed in a baking equipment and baked at 150℃ to 170℃ (e.g., 160℃) for 20-30 minutes (e.g., 25 minutes) to fully cure it. The thickness of the cured fluorocarbon anti-oxidation bonding layer 3 is about 70-90μm (e.g., 80μm). This layer has three key functions: First, it has extremely strong adhesion to the copper substrate, forming a solid underlayer; second, its dense film layer can effectively isolate oxygen and moisture, providing long-term anti-oxidation protection for the copper substrate, with a theoretical lifespan of more than 30 years; third, it provides an excellent adhesion interface for subsequent UV inks.

[0033] Next, the required artistic pattern is constructed on the fluorocarbon anti-oxidation bonding layer 3 in two steps using digital UV printing technology. First, according to the designed pattern data, a UV flatbed printer is used to print transparent or semi-transparent UV varnish on the area where a three-dimensional raised effect is required. By controlling the number of printing passes, the material can be precisely stacked. After being cured by ultraviolet light, a UV-cured embossed pattern layer 4 is formed. The thickness of this layer is controlled at 0.3-0.5mm (e.g., 0.4mm). Its outer surface is made of micro-frosted texture through material formulation or post-treatment. Because this layer is transparent, the copper plate brushed texture underneath is clearly visible, visually as if the brass itself is embossed. The micro-frosted surface and the bright brushed background form a delicate visual contrast.

[0034] The second step of printing is then performed using the same or another UV flatbed printer. Color UV ink is loaded and printed on the area complementary to the UV-cured embossed pattern layer 4 (i.e., the area not covered by the embossing). After UV curing, a UV-cured color pattern layer 5 is formed. Importantly, the UV-cured embossed pattern layer 4 and the UV-cured color pattern layer 5 are formed by printing in stages. The two layers do not overlap much in the thickness direction or only slightly overlap at the boundary, thus ensuring the three-dimensional purity of the embossing and the vividness and fullness of the colors, together forming a complete image.

[0035] To further enhance durability, a transparent outer protective color-fixing layer 6 can be applied over the UV-cured embossed pattern layer 4 and the UV-cured colored pattern layer 5. This layer can be a high-performance UV protective varnish or a fluorocarbon transparent topcoat, applied by spraying. After curing, it can enhance the scratch resistance, UV resistance and stain resistance of the image, forming a dual protection system.

[0036] Example 2: Based on Example 1, this example further defines the mounting structure of the copper plate image board to ensure its flatness, stability and maintainability during use.

[0037] like Figure 1 and Figure 2 As shown, the copper plate image board also includes mounting components, which mainly include a backing board 8. These components are typically made of multi-layer solid wood boards, high-density boards, or aluminum composite panels, which have a certain thickness and rigidity, for example, 9-12mm. Crucially, the lower surface of the brass substrate layer 1 is bonded to the backing board 8 via a removable double-sided adhesive layer 7. The removable double-sided adhesive layer 7 is preferably made of PET (polyethylene terephthalate) double-sided tape, with a thickness of 0.15-0.20mm (e.g., 0.18mm). This PET double-sided adhesive has excellent initial tack and holding power, and its long-term operating temperature can reach 100-120℃, with even higher short-term temperature resistance, ensuring durable reliability of the bonding under normal conditions.

[0038] During installation, the removable double-sided adhesive layer 7 is fully applied between the entire lower surface of the brass plate substrate layer 1 and the corresponding mating surface of the back plate 8. By applying uniform pressure, the copper plate body 100 and the back plate 8 are tightly bonded together through the adhesive layer. This "surface contact" full back-side bonding method combines the thin copper plate body 100 with the heavy back plate 8 into a rigid composite. The strength of the back plate completely offsets the internal stress or warping deformation tendency that may occur in the thin copper plate, thus ensuring the absolute flatness of the picture during use and hanging. More importantly, the removable double-sided adhesive layer 7 has the characteristic of being "removable". When it is necessary to replace the back plate, repair the frame, or remove the painting core for preservation in the future, the copper plate body can be peeled off from the back plate relatively easily and without damage. After the PET adhesive layer is removed, there will be no hard-to-remove adhesive residue or damage on the back of the precious copper plate painting core. This greatly facilitates the long-term maintenance, transportation, and recycling of the artwork, reflecting the environmental protection and user-friendly design concept.

[0039] The working principle and process of this utility model are as follows: First, the copper plate is given a unique metallic texture through wire drawing and micro-polishing processes. Then, the fluorocarbon anti-oxidation bonding layer provides the copper plate with "armor"-like basic protection. Next, digital UV printing technology is used to transparently build up a three-dimensional relief, and then fill it with brilliant colors, realizing artistic creation step by step. Finally, the removable PET double-sided adhesive is used for scientific mounting, which not only ensures flatness and stability during display, but also leaves room for damage-free maintenance in the future. The entire technical solution is interconnected, and together they achieve a perfect unity of artistic expression, long-term protection and convenient maintenance.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
