Description

Technical Field

[0001] This utility model relates to the field of resin craft processing technology, specifically to a surface structure with metallic texture and wear resistance. Background Technology

[0002] Resin crafts processing is a technology that uses resin as a base material to create decorative items through processes such as mold casting and surface treatment. Its core steps include mold making, raw material preparation, curing and molding, and surface treatment. Among these, the surface structure of resin products plays a major role in resin crafts, which can enhance aesthetics, imitate the effects of materials such as copper, gold, and jade to enhance visual appeal, and also enhance durability, prevent surface scratches and wear, and extend the lifespan of the crafts.

[0003] Prior art 1 (Chinese patent application CN202410320138.3, filed on 2024-03-20) discloses a composite sheet and its manufacturing method and composite structure, including a first resin layer, a metal layer and a second resin layer. The first resin layer includes opposing first surfaces, a second surface and a plurality of first resin protrusions, the plurality of first resin protrusions protruding from the second surface. The metal layer includes opposing third surfaces, a fourth surface and a plurality of metal protrusions, the metal layer being fixed to the second surface via the third surface, the plurality of metal protrusions protruding from the fourth surface and corresponding to the plurality of first resin protrusions. The second resin layer includes opposing fifth surfaces, a sixth surface and a plurality of second resin protrusions, the second resin layer being removably disposed on the fourth surface via the fifth surface, the plurality of second resin protrusions protruding from the sixth surface and corresponding to the plurality of metal protrusions. During the hot pressing step, the second resin layer can protect the metal layer, which is beneficial to maintaining the surface gloss of the metal layer, so that the composite sheet and composite structure after being manufactured have a brighter visual effect.

[0004] Prior art 2 (Chinese patent application CN201810553630.X, filed on 2018-05-31) discloses a metal-plastic composite, its preparation method and application, including a metal substrate, a metal-resin particle composite coating formed on the metal substrate, and a plastic layer formed on the metal-resin particle composite coating. The metal-resin particle composite coating includes a matrix metal layer and resin particles dispersed in the matrix metal layer, and at least some of the resin particles are bonded to the plastic layer. The resin particles and metal are co-deposited on the surface of the metal substrate by dispersion electroplating, thereby obtaining a metal-resin particle composite coating with a uniformly distributed resin particle structure in the matrix metal. By fusing the resin particles on the surface of the coating with the plastic layer described later, the bonding force between the metal and the plastic layer can be significantly improved.

[0005] Although existing technologies can protect resin crafts, there are still some shortcomings in the process. Traditional resin crafts use a single metal plating layer, which has limited hardness and is easily scratched and worn. In addition, traditional resin crafts use electroplating or spraying processes, which have insufficient adhesion and the plating layer is easy to peel off after long-term use. Utility Model Content

[0006] The purpose of this utility model is to provide a surface structure with metallic texture and wear resistance, so as to solve the problems mentioned in the background art, that traditional resin crafts use a single metal coating, which has limited hardness and is easily scratched and worn, and that traditional resin crafts use electroplating or spraying processes, which have insufficient adhesion and the coating is easy to fall off after long-term use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a surface structure with metallic texture and wear resistance, comprising a substrate layer, wherein a composite coating mechanism is provided on the top of the substrate layer, the composite coating mechanism comprising a bottom layer, a functional layer, a protective layer and a texture layer arranged from bottom to top, and an anti-peeling mechanism is provided between the substrate layer and the bottom layer.

[0008] As a preferred technical solution of this application, the thickness of the substrate layer is set to 1 mm, and the substrate layer is made of polyurethane resin.

[0009] As a preferred technical solution of this application, the thickness of the bottom layer is set to 50μm, and the bottom layer is a mixture of epoxy resin and polyurethane.

[0010] As a preferred technical solution of this application, the thickness of the functional layer is set to 3μm, and the material of the functional layer is set to TiC-TiN composite metal layer material.

[0011] As a preferred technical solution of this application, the thickness of the protective layer is set to 10 μm, and the protective layer is made of nano-silica-alumina composite material.

[0012] As a preferred technical solution of this application, the anti-peeling mechanism includes a first toothed structure disposed on the top surface of the substrate layer and a second toothed structure disposed on the bottom surface of the bottom layer.

[0013] As a preferred technical solution of this application, an anchoring hole is provided through one side surface of the first tooth-shaped structure. The anchoring hole is square in shape and is evenly distributed on one side surface of the first tooth-shaped structure. Anchoring blocks are provided on both sides of the outer wall of the second tooth-shaped structure, and the anchoring blocks are evenly distributed on one side surface of the second tooth-shaped structure.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This surface structure, possessing both metallic texture and wear resistance, utilizes a multi-layer composite structure design. The functional layer and protective layer form a high-hardness protection, solving the problem of easy scratching in traditional coatings and significantly improving wear resistance. Furthermore, the bottom layer, functional layer, and protective layer disperse stress through thickness gradients, preventing interface cracking and extending service life. Additionally, an anti-peeling structure is provided between the substrate layer and the bottom layer to prevent the composite coating structure from peeling off, effectively improving the adhesion between the substrate and the composite coating structure. This effectively solves the industry pain point of difficulty in achieving both metallic texture and wear resistance in the surface treatment of resin crafts. Specific details are as follows: 1. The composite coating structure consists of a bottom layer, a functional layer, and a protective layer, forming a sandwich structure. The thickness gradient design achieves stress buffering and avoids interface cracking. The epoxy resin-polyurethane hybrid layer at the bottom provides flexibility, the TiC-TiN layer of the functional layer imparts metallic luster and high hardness, the nano-ceramic film of the protective layer enhances scratch resistance, and the texture layer can enhance the visual metallic texture. This effectively solves the problem of traditional resin crafts using a single metal coating, which has limited hardness and is easily scratched and worn.

[0015] 2. The second tooth-shaped structure of the bottom layer and the first tooth-shaped structure of the substrate layer interlock with each other to form a mechanical interlock, which effectively enhances the interfacial bonding force. Furthermore, through the cooperation between the anchoring block of the bottom layer and the anchoring hole of the substrate layer, a radial anchoring force is generated, which restricts the peeling of the composite coating mechanism and further improves the anti-peeling ability of the composite coating mechanism and the substrate layer.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0019] Please see Figures 1-7 The present invention provides the following technical solution: a surface structure with metallic texture and wear resistance.

[0020] Example 1: To address the problem that traditional resin crafts, using a single metal plating layer, have limited hardness and are easily scratched and worn, please refer to... Figures 1-4 The system includes a substrate layer 1, with a composite coating mechanism on top of the substrate layer 1. The composite coating mechanism includes a bottom layer 2, a functional layer 3, a protective layer 4, and a texture layer 5 arranged from bottom to top. The thickness of the substrate layer 1 is 1 mm and it is made of polyurethane resin. The thickness of the bottom layer 2 is 50 μm and it is made of a mixture of epoxy resin and polyurethane. The thickness of the functional layer 3 is 3 μm and it is made of TiC-TiN composite metal layer material. The thickness of the protective layer 4 is 10 μm and it is made of nano-silica-alumina composite material.

[0021] In use, the resin craft is cleaned and dried to remove surface grease and impurities. The substrate layer 1 is coated onto the surface of the craft, followed by the underlayer 2, which is an epoxy resin-polyurethane mixture in a 3:2 ratio. This mixture is evenly coated onto the substrate surface using a spraying device, with a thickness controlled at 50 μm. The underlayer 2 is then baked at 80°C for 30 minutes to cure. Next, the resin craft coated with underlayer 2 is placed in a vacuum ion plating apparatus, where TiC and TiN targets are deposited alternately to form a functional layer 3 with a thickness of 3 μm. Then, a nano-silica-alumina mixture is evenly coated onto the surface of functional layer 3 using a spraying device and cured under UV light to form a protective layer. The protective layer 4 has a thickness of 10μm. Finally, a micron-level texture, such as a brushed, mirror, or matte effect, is formed on the surface of the protective layer 4 by laser engraving, forming a texture layer 5. This enhances the visual metallic texture, while dispersing stress and improving wear resistance. The bottom layer 2, functional layer 3, and protective layer 4 of the composite coating structure form a sandwich structure. The thickness gradient design achieves stress buffering and avoids interface cracking. The epoxy resin-polyurethane hybrid layer of the bottom layer 2 provides flexibility, the TiC-TiN layer of the functional layer 3 imparts metallic luster and high hardness, and the nano-ceramic film of the protective layer 4 improves scratch resistance. This effectively solves the problem that traditional resin crafts use a single metal coating, which has limited hardness and is easily scratched and worn.

[0022] Example 2: To address the problem of insufficient adhesion and easy peeling of the coating after long-term use in traditional resin crafts using electroplating or spraying processes, such as... Figure 1 , Figure 2 , Figures 5-7 The technical solution shown includes an anti-peeling mechanism between the substrate layer 1 and the bottom layer 2. The anti-peeling mechanism includes a first tooth-shaped structure 6 on the top surface of the substrate layer 1 and a second tooth-shaped structure 7 on the bottom surface of the bottom layer 2. An anchoring hole 8 is provided through one side surface of the first tooth-shaped structure 6. The anchoring hole 8 is square in shape and is evenly distributed on one side surface of the first tooth-shaped structure 6. An anchoring block 9 is provided on both sides of the outer wall of the second tooth-shaped structure 7. The anchoring block 9 is also evenly distributed on one side surface of the second tooth-shaped structure 7.

[0023] In use, after the substrate layer 1 is coated onto the surface of the craft item, a first tooth-like structure 6 is formed on the surface of the substrate layer 1 by laser engraving. An anchoring hole 8 is drilled through one side of the first tooth-like structure 6. Then, when the bottom layer 2 is sprayed, a second tooth-like structure 7 and an anchoring block 9 are formed at the bottom of the bottom layer 2. The second tooth-like structure 7 and the first tooth-like structure 6 interlock, forming a mechanical interlock, effectively enhancing the interfacial bonding force. Furthermore, the cooperation between the anchoring block 9 and the anchoring hole 8 generates a radial anchoring force, restricting the peeling of the composite coating mechanism and further improving the anti-peeling capability between the composite coating mechanism and the substrate layer 1.

[0024] The above is the entire working process of the device, and the contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
