Description

Technical Field

[0001] The invention belongs to the technical field of metal plates, and in particular relates to a manufacturing process of a mirror metal plate. Background Art

[0002] Metal sheets refer to metal blanks that are processed into flat materials with a certain thickness, width and length through metal pressure processing techniques such as rolling, drawing, extrusion, etc. They are widely used in the fields of construction, automobiles, ships, machinery manufacturing, home appliances, hardware products, etc. There are many types of metal sheets, which can be divided into ferrous metal sheets (such as steel plates, iron plates) and non-ferrous metal sheets (such as aluminum plates, copper plates, titanium plates, etc.) according to the material. Metal sheets are widely used in a wide range of fields, especially in the surface decoration of objects. They have the advantages of being beautiful, durable, and inexpensive. However, when metal sheets need to choose different colors, spraying, electroplating, lamination, polishing and other processes are usually used.

[0003] However, although the traditional manufacturing process can spray different colors, it cannot make the surface of the metal sheet achieve a mirror effect; electroplating can achieve a mirror effect, but the process itself has high manufacturing costs and is not environmentally friendly; although the lamination method can make the surface of the metal sheet smooth, it is easily scratched and not durable; the polishing process takes a long time and is not suitable for large-scale production. Summary of the invention

[0004] The purpose of the present invention is to provide a manufacturing process of a mirror metal sheet in order to solve the above-mentioned problem.

[0005] The technical solution adopted by the present invention is as follows: a manufacturing process of a mirror metal sheet, the manufacturing process comprising the following steps:

[0006] S1: The metal sheet is leveled by a leveling device to ensure that its surface is flat and smooth in preparation for subsequent steps;

[0007] S2: Mix the ink and resin material mixture according to the proportion, add nitrogen in a sealed container at 120°C and stir thoroughly to ensure that the mixture is uniform;

[0008] The resin material mixture includes: acrylic resin 65% to 70%; polyurethane resin 20% to 25%; photoinitiator 5%; filler 5%;

[0009] S3: injecting the prepared mixture into a glue coating machine and evenly applying it on one side of the plastic film to form a thin coating;

[0010] S4: passing the plastic film coated with the mixture through a laminating machine and pressing it against the leveled metal sheet to ensure that the mixture is in full contact with the metal surface;

[0011] S5: placing the coated metal sheet at a suitable temperature and waiting for the mixture to completely solidify to form a hard mirror layer;

[0012] S6: After the mixture is completely cured, the plastic film is torn off the metal sheet to expose the metal sheet with a mirror effect;

[0013] S7: Perform post-processing as needed, including cutting and punching, to process the mirror metal sheet into a desired shape and size;

[0014] S8: Inspect the final product to ensure that its surface is smooth and flat, without scratches, bubbles and other defects, and meets the use requirements;

[0015] S9: Package qualified mirror metal sheets to prevent damage during transportation and storage.

[0016] In a preferred embodiment, in step S1, the leveling process is performed using a leveling device, including a cold rolling mill, a stretching machine, etc. The surface of the metal sheet after leveling should reach a roughness of Ra 0.2 μm or less, and be free of defects such as scratches and pits. During the leveling process, the feeding speed of the metal sheet is controlled at 10 m / min to 30 m / min, and the leveling pressure is adjusted between 50 MPa and 150 MPa according to the thickness and hardness of the metal sheet.

[0017] In a preferred embodiment, in step S2, the filler includes: glass beads: 1.5%, diatomaceous earth: 0.5%, mica powder: 1%, calcium carbonate: 1%, antibacterial agent chitosan: 0.5%, ultraviolet absorber titanium dioxide: 0.5%.

[0018] In a preferred embodiment, in the step S3, during the gluing process, a gluing machine is used to evenly apply the mixture on one side of the plastic film to form a thin coating. The amount of glue applied by the gluing machine should be controlled between 0.1 mm and 0.2 mm to ensure uniform coating thickness. After the gluing is completed, the plastic film coated with the mixture needs to be placed at room temperature for 10 to 30 minutes to allow the mixture to initially solidify. The gluing speed of the gluing machine is controlled between 0.5 m / min and 1 m / min to ensure uniform coating.

[0019] In a preferred embodiment, in step S4, the temperature and pressure of the laminating machine should be adjusted according to the viscosity of the mixture and the material of the metal sheet to ensure the laminating effect. The laminating temperature is usually controlled at 60°C to 80°C, and the laminating pressure is controlled at 0.5MPa to 1MPa. After the laminating is completed, the laminating metal sheet needs to be placed at room temperature for 10 minutes to 30 minutes to further solidify the mixture.

[0020] In a preferred embodiment, in step S5, during the curing process, the coated metal sheet needs to be placed at a suitable temperature to wait for the mixture to be completely cured. The curing temperature is generally 60°C to 80°C, and the curing time is 2 hours to 4 hours. During the curing process, the temperature and humidity need to be kept stable to ensure the curing effect. During the curing process, the metal sheet should be placed in a manner to ensure that the mixture is evenly heated to avoid local overheating or too fast cooling.

[0021] In a preferred embodiment, in step S6, the film tearing speed is controlled at 0.5 m / min to 1 m / min to ensure a smooth film tearing process. After the film tearing is completed, the surface of the metal sheet should have a smooth and flat mirror effect.

[0022] In a preferred embodiment, in step S7, the parameters of cutting and punching should be adjusted according to the material, thickness and processing requirements of the mirror metal sheet to ensure the processing effect. The cutting speed is controlled at 10m / min to 30m / min, and the punching pressure is controlled at 50MPa to 150MPa. During the processing, the processing accuracy should be ensured to avoid affecting the mirror effect.

[0023] In a preferred embodiment, in step S8, the inspection standard should be formulated according to customer requirements or industry standards to ensure that the product quality meets the requirements. During the inspection process, optical microscopes and surface roughness measuring instruments are used for inspection. The inspection frequency should be adjusted according to the production batch and inspection requirements.

[0024] In a preferred embodiment, in step S9, the packaging material is usually a moisture-proof, dust-proof, and impact-proof material, such as foam plastics, cartons, etc. The packaging method should ensure that the metal sheet is firmly fixed in the packaging box to avoid movement or collision during transportation. After packaging, it should be marked with information such as product name, specifications, quantity, and production date.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, a special mixture is coated on a metal sheet and a smooth plastic film is used for lamination. After the plastic film is finally torn off, the surface of the metal sheet can achieve a mirror effect. This mirror effect is not only beautiful, but also can enhance the grade and attractiveness of the product, making it more competitive in the market. This manufacturing process can effectively improve the scratch resistance of the surface of the metal sheet. This is because the resin material and filler in the mixture can form a hard protective layer, thereby reducing the risk of scratches on the surface of the metal sheet. At the same time, the resin material and filler in the mixture have good weather resistance, can resist the influence of environmental factors such as ultraviolet rays and oxygen to a certain extent, and extend the service life of the product. By adjusting the type and proportion of ink in the mixture, mirror metal sheets of different colors can be produced to meet the needs of different customers.

[0027] 2. In the present invention, the glass microbeads inside the filler improve the fluidity and density of the plate, enhance the surface finish and mirror effect; diatomaceous earth absorbs impurities through its porous structure, improves the cleanliness and stability of the filler layer, and enhances wear resistance and corrosion resistance; mica powder improves mechanical strength and thermal stability, while improving lubricity; calcium carbonate increases hardness and wear resistance, reduces costs, and optimizes printing and finishing performance; antibacterial agent chitosan gives the plate antibacterial properties, which are suitable for fields with high hygiene requirements; ultraviolet absorber titanium dioxide protects the plate from ultraviolet damage, prevents aging, and improves reflectivity and color. The comprehensive application of these fillers not only improves the surface quality and mechanical properties of the mirror metal plate, but also gives it functional characteristics, optimizes the processing process, and thus enhances the market competitiveness of the product.
