Description

Technical Field

[0001] The present invention relates to the technical field of fishing tools, and in particular to a bionic fishing bait based on an enamel-like cladding process and a preparation method thereof. Background Art

[0002] Current bionic fish baits on the market face numerous technical bottlenecks in practical application. While traditional plastic baits are relatively inexpensive, they are susceptible to material aging and surface fading after prolonged immersion in water. Their bionic patterns are easily worn and blurred by the impact of water flow and fish bites, making them difficult to maintain their visual appeal to fish. Conventional metal baits, while durable, are limited by their surface treatment processes and often offer only a single metallic sheen or simple coating. They are unable to accurately simulate the color gradients and textures of natural fish food, significantly reducing their effectiveness in attracting fish in complex aquatic environments.

[0003] In existing fishing lures, there's a significant technological gap between biomimetic design and surface treatment processes. On the one hand, biomimetic design often relies on empirical experimentation, lacking systematic research into fish visual perception mechanisms. This results in a poor match between the biomimetic design and fish feeding preferences. On the other hand, surface finishing processes like electroplating and spraying create coatings with limited bonding strength to the substrate, making them prone to peeling and cracking during fishing. Furthermore, the coating's optical refractive index differs significantly from the surface characteristics of aquatic organisms, making it difficult to simulate the dynamic visual signals of natural organisms through light reflection and refraction. This makes it difficult for existing fishing lures to achieve breakthroughs in improving their fish-attracting efficiency and longevity.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0005] In response to the problems in the related art, the present invention proposes a bionic fish bait based on an enamel-like cladding process and a preparation method thereof to solve the problems of poor bionic effect, insufficient durability and single appearance of bionic fish baits in the prior art. By coating an enamel-like glue layer on the surface of the metal base material, the fish bait has excellent bionic effect, high durability and rich and diverse appearance, thereby improving the success rate of fishing and overcoming the above-mentioned technical problems existing in the existing related art.

[0006] The technical solution of the present invention is achieved as follows:

[0007] In one aspect, the present invention:

[0008] A bionic fish bait based on an enamel-like cladding process, comprising: a metal base layer and an enamel-like glue layer, wherein;

[0009] The enamel-like glue layer is mechanically combined with the metal base layer through an engraving and depression process, with a firing temperature of 100° C.-500° C. and a thickness of 0.2-0.5 mm, to form a bionic structure with a specific pattern or shape on the surface of the metal base layer.

[0010] Furthermore, the metal bottom layer is any one of zinc alloy, lead or copper.

[0011] Furthermore, the enamel glaze of the enamel-like glue dripping layer is a color paste.

[0012] Furthermore, the raw materials of the color paste include, by weight percentage, 10-20% resin and 80-90% pigment.

[0013] Furthermore, the engraving depression of the engraving process has a depth of 0.1-0.5 mm, and the bottom of the depression forms an inverted trapezoidal locking structure with the metal bottom layer, with an included angle of 60°-80°.

[0014] Another aspect of the present invention is:

[0015] A method for preparing a bionic fishing bait based on an enamel-like cladding process, which is used to prepare the bionic fishing bait based on the enamel-like cladding process, comprises the following steps:

[0016] Based on the visual characteristics of fish, bionic patterns or shapes are designed in advance using CAD software;

[0017] The metal base body is prepared by die-casting or stamping process, and the surface roughness is controlled to Ra≤1.6μm;

[0018] Depressions are carved on the surface of the body and filled with enamel glaze. After being fired at 100℃-500℃, it is polished and baked again at 60℃-160℃ to form the finished product.

[0019] The filling of the enamel glaze comprises: the filling amount of the enamel glaze is 100%-110% of the volume of the depression, and the oxygen content in the furnace during firing is 5%-8%.

[0020] The grinding and polishing process includes the following steps: initial grinding with 200-mesh coarse sandpaper, followed by fine grinding with 400-mesh, 600-mesh, and 800-mesh sandpaper, and finally mechanical polishing with a wool wheel and polishing paste, with the surface glossiness being ≥80GU.

[0022] Through the carefully designed pattern or shape, as well as the color and texture of the enamel-like glue layer, the present invention enables the bait to realistically simulate fish food or other objects that attract fish, significantly enhancing the bait's biomimetic effect and increasing the chance of catching fish. Furthermore, the enamel-like glue layer is firmly bonded to the metal base, offering advantages such as high hardness, wear resistance, and corrosion resistance. It effectively resists aquatic erosion and wear during use, extending the bait's service life. Furthermore, the enamel glaze offers a wide range of colors and glossiness. Through different designs and processes, a variety of exquisitely designed biomimetic baits can be produced to meet the needs of different anglers and the requirements of various fishing scenarios.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0027] According to an embodiment of the present invention, a bionic fishing bait based on an enamel-like cladding process is provided.

[0028] According to an embodiment of the present invention, a bionic fish bait based on an enamel-like cladding process includes: a metal base layer and an enamel-like glue layer, wherein; the enamel-like glue layer is mechanically combined with the metal base layer through an engraving and depression process, the firing temperature is 100°C-500°C, the thickness is 0.2-0.5mm, and a bionic structure with a specific pattern or shape is formed on the surface of the metal base layer.

[0029] The metal base is made of metal material, which is selected from zinc alloy, lead, copper and other materials with a certain density and strength to ensure that the bait has a suitable sinking speed and stability in the water. Among them, the zinc alloy is selected from Zamak3 brand, containing 3.5%-4.3% aluminum and less than 0.03% copper, with a density of 6.6-6.7g / cm 3 , ensuring a sinking speed of 0.5-0.8m / s; the purity of the lead material is ≥99.9%, and is used in deep-sea fishing bait scenes that require high specific gravity.

[0030] The enamel glaze of the enamel-like glue-dried layer is a color paste, and the raw materials of the color paste include, by weight percentage, 10-20% of resin and 80-90% of pigment.

[0031] In addition, the engraving depression depth of the engraving depression process is 0.1-0.5 mm, and the bottom of the depression forms an inverted trapezoidal locking structure with the metal bottom layer, with an angle of 60°-80°.

[0032] According to an embodiment of the present invention, a method for preparing a bionic fishing bait based on an enamel-like cladding process is provided.

[0033] like Figure 1-Figure 2 As shown, the method for preparing a bionic fishing bait based on an enamel-like cladding process according to an embodiment of the present invention is used to prepare the bionic fishing bait based on the enamel-like cladding process, comprising the following steps:

[0034] Step S1: Design the pattern or shape of the bait based on the fish's living habits and visual characteristics. By thoroughly researching the preferences of target fish, such as certain fish species' sensitivity to specific colors, shapes, or patterns, the design is then developed to create a pattern or shape that matches the bait's characteristics and mimics its appearance. Computer-aided design (CAD) software is then used to create a three-dimensional model of the designed pattern or shape, allowing for more intuitive observation and adjustment of the design, ensuring that the bait appears natural and realistic in the water, attracting the fish's attention.

[0035] Step S2, select a suitable metal material, such as zinc alloy, lead, copper, etc. According to the characteristics of the metal material, select a suitable process such as die-casting or stamping to prepare the tire body shape. Among them, for zinc alloy materials, when using the die-casting process, first prepare the die-casting mold, heat the zinc alloy to a molten state, and then inject the molten zinc alloy into the mold under high pressure, and obtain the desired tire body shape after cooling. The die-casting process can produce tire bodies with complex shapes and high dimensional accuracy. Among them, if copper material is used, a stamping process can be used. A stamping mold is made according to the designed shape, and the copper sheet is stamped to obtain the preliminary shape of the tire body. The stamping process is suitable for the production of tire bodies with relatively simple shapes and mass production.

[0036] Specifically, in the process of making the body, the size and shape accuracy of the body are strictly controlled to ensure that the body surface is smooth and burr-free, laying a good foundation for the subsequent glaze filling and firing processes.

[0037] Step S3, the body is processed with carved depressions filled with enamel. According to the designed pattern or shape, use professional carving tools to carve the corresponding recessed areas on the surface of the body. During the carving process, attention should be paid to the depth and precision of the carving to ensure that the shape and size of the recessed area are consistent with the design requirements. Then the glaze filling operation is carried out. Select enamel glaze that matches the design color and effect, and fill the enamel glaze evenly into the carved recessed area. When filling the glaze, pay attention to the filling amount of the glaze to avoid insufficient or excessive filling. Insufficient filling will result in insufficient thickness of the enamel-like glue layer, affecting the appearance and durability; excessive filling will produce defects such as bubbles during the firing process.

[0038] In step S4, the glazed workpiece is placed in a high-temperature furnace for firing. The appropriate firing temperature and time are set based on the type and properties of the enamel glaze and the substrate material. For copper substrates, the firing temperature is controlled between 450°C and 500°C, with a holding time of 15-20 minutes and a heating rate of ≤5°C / s. For zinc alloys, the temperature is adjusted to 400°C to 450°C to prevent overheating and deformation of the metal, with a heating rate of ≤5°C / s. Generally speaking, the firing temperature is usually between 100°C and 500°C, and the firing time is adjusted according to the size and thickness of the workpiece, usually 10-30 minutes.

[0039] Furthermore, during the firing process, the temperature rise and fall rate within the furnace must be strictly controlled to avoid sudden temperature changes that could cause cracking or other defects in the work. The high temperature melts the enamel glaze and firmly bonds it to the metal body, forming a hard, smooth, enamel-like layer.

[0040] Step S5: The fired workpiece may have surface defects such as unevenness or bubbles, requiring polishing. First, use coarse sandpaper to perform a preliminary polishing of the workpiece's surface to remove obvious unevenness and larger defects. Then, use fine sandpaper for fine polishing, gradually smoothing the surface. After polishing, the workpiece is polished. This can be done mechanically or manually, using a polishing compound and polishing tools.

[0041] Step S6, after polishing, it is baked again at 60°C-160°C to increase the glossiness of the work, make the surface of the bait more beautiful, and improve its visual appeal in the water.

[0042] Specifically, during the implementation process, a bionic fishing bait was designed with the goal of simulating a small fish. The specific implementation process is as follows:

[0043] By studying the visual responses of target fish to small fish, the lure's streamlined shape and silver-gray and blue stripes were chosen to simulate the appearance of a small fish. CAD software was used for 3D modeling to determine the specific dimensions and pattern details of the lure.

[0044] Zinc alloy is selected as the base material, and the carcass is produced using a die-casting process. After preparing the corresponding die-casting mold, the zinc alloy is heated to a molten state at 400-450°C. The molten zinc alloy is then injected into the mold under a pressure of 100-150 MPa. After cooling, a streamlined carcass is obtained. The carcass undergoes surface treatment to remove burrs and uneven areas, resulting in a smooth surface.

[0045] According to the designed pattern, use a carving tool to carve the recessed areas corresponding to the silver-gray and blue stripes on the body surface. Choose silver-gray and blue enamel glazes and fill the corresponding recessed areas with the silver-gray glaze until it is flush with the body surface. Then fill it with the blue glaze, ensuring a clear boundary between the two glaze colors.

[0046] Place the glazed bait in a high-temperature furnace at 850°C for 15 minutes. Control the temperature within the furnace to increase and decrease at a rate of 5°C / minute and 3°C / minute. After firing, remove the bait and allow it to cool naturally.

[0047] Use 200-grit coarse sandpaper to initially sand the lure's surface to remove any surface irregularities and any small bubbles. Then, use 400-grit, 600-grit, and 800-grit fine sandpaper for a fine, smooth surface. Finally, polish the lure using a polishing machine and polishing paste, resulting in a high-gloss, beautifully crafted bionic enamel lure.

[0048] In addition, specifically, during the implementation process, a bionic fishing bait simulating an insect was designed. It has an oval shape, alternating brown and green colors, and a surface texture similar to insect wings. The specific implementation is as follows:

[0049] Detailed patterns and shapes are designed using CAD software, determining the size and texture details of the bait.

[0050] Copper is used as the material and the carcass is produced through a stamping process. A stamping die is made according to the designed elliptical shape, and the copper sheet is stamped to obtain the initial shape of the carcass. The carcass is then trimmed and polished to achieve a smooth surface and meet the required dimensions.

[0051] Carve out brown and green textured recessed areas on the surface of the body. Select brown and green enamel glazes and fill the recessed areas in the designed pattern, paying attention to the filling amount and uniformity of the glaze.

[0052] Place the glazed bait in a high-temperature furnace at 450°C for 20 minutes. Control the temperature at 6°C / minute and 4°C / minute. After firing, allow the bait to cool slowly in the furnace.

[0053] First, use coarse sandpaper to remove surface defects, then use fine sandpaper to gradually smooth it out, and finally polish it to make the surface of the bait have a natural luster and texture, better simulating the appearance of insects.

[0054] In addition, a durability comparison experiment was conducted on the bionic fishing bait prepared by the present invention based on the enamel-like cladding process, as follows:

[0055] Among them, a salt spray corrosion test (5% NaCl solution, 35° C.) was conducted, and the test samples included the bait of the present invention, the traditional plastic bait, and the electroplated metal bait. The specific test results and experimental data are shown in Table 1:

[0056] Table 1 Durability comparison test data

[0057] Testing time Fishing bait of the present invention Traditional plastic fishing bait Electroplated metal fishing lures 24h No change Slightly faded The coating begins to turn white 96h No change Color faded 40% Large area of ​​coating peeling 168h No change Surface cracking Base metal corrosion

[0058] Among them, the wear resistance test (friction tester, 1000 cycles) was carried out, and the test conditions were: load 5N, friction speed 20 times / minute; the specific test results and experimental data are shown in Table 2:

[0059] Table 2 Wear resistance test data

[0060] Sample type Surface gloss retention Pattern clarity Fishing bait of the present invention ≥90％ No obvious wear Traditional paint bait ≤50％ Blurred pattern

[0061] The salt spray and wear test data from the aforementioned experiments highlight the long-lasting advantages of the enamel process. After 96 hours in a 5% NaCl salt spray environment, conventional plastic fish baits faded 40% and cracked, while electroplated metal fish baits experienced flaking. However, the enamel-like glue layer of the present invention remained unchanged. Its Vickers hardness of 500-600 HV ensured a gloss retention rate exceeding 90% after wear testing, nearly double the 50% retention rate of conventional painted fish baits. This enhanced corrosion and wear resistance stems from the dense glassy structure of the enamel-like glue layer, matched with the chemical inertness of the metal substrate, enabling the fish bait to maintain its appearance integrity and functional stability in diverse water environments, including seawater and freshwater.

[0062] In addition, a comparative experiment on fish attracting effect was conducted, and the specific parameters are as follows:

[0063] Experimental location: a freshwater reservoir (bass population density 0.8 tails / 100m 2); Experimental time: 3 days, 9-11 am daily; Control group: commercially available plastic bionic fish bait (Type A) and metal sequin bait (Type B); Experimental group: the fish bait of the present invention (Type C, blue glaze). Specific experimental results are shown in Table 3:

[0064] Table 3 Fish attracting effect data table

[0065] Bait type Number of throws Number of bites Success rate Type A 50 12 24％ Type B 50 18 36％ Type C 50 31 62％

[0066] With the help of the above experiments, the water experimental data directly verified the technological breakthrough of bionic design. 2 In a freshwater reservoir, the invention's 62% fish-attracting success rate was a 158% improvement over commercially available plastic bait (24%) and a 72% improvement over metal sequin bait (36%). High-speed video footage revealed that fish reacted to the bait in an average of just 1.2 seconds, one-third the time of conventional baits. This success is attributed to the enamel-like resin layer's 1.48 refractive index, which optically simulates the surface of small fish. Combined with the three-dimensional texture created by the engraved depressions, this creates a dynamic light and shadow effect in the water, resembling a living creature. Experiments revealed that fish pecked at the bait 2.3 times more often than with conventional baits, confirming the design's effectiveness in stimulating fish predatory instincts.

[0067] In summary, with the help of the above technical solution of the present invention, the following effects can be achieved:

[0068] Through the carefully designed pattern or shape, as well as the color and texture of the enamel-like glue layer, the present invention enables the bait to realistically simulate fish food or other objects that attract fish, significantly enhancing the bait's biomimetic effect and increasing the chance of catching fish. Furthermore, the enamel-like glue layer is firmly bonded to the metal base, offering advantages such as high hardness, wear resistance, and corrosion resistance. It effectively resists aquatic erosion and wear during use, extending the bait's service life. Furthermore, the enamel glaze offers a wide range of colors and glossiness. Through different designs and processes, a variety of exquisitely designed biomimetic baits can be produced to meet the needs of different anglers and the requirements of various fishing scenarios.
