Description

Technical Field

[0001] This invention relates to the technical field, and more particularly to a production process for a brushed black titanium nano-coating for decorative panels. Background Technology

[0002] Brushed black titanium nano-coating is a special coating applied to metal surfaces, possessing unique appearance and performance characteristics. It is commonly used to decorate and enhance the visual appeal and durability of products. Specifically, during the production of metal decorative panels, a black titanium nano-coating is applied to the surface of the metal panels to protect them.

[0003] The general process for applying black titanium nano-coatings to metal substrates is as follows: substrate preparation, wire drawing, cleaning and pretreatment, coating application, and drying. While this process can achieve the application of black titanium nano-coatings to the surface of the device plate, it suffers from several drawbacks. First, the wire drawing process relies heavily on fixed wire drawing equipment, which is cumbersome and time-consuming, hindering efficient application of the black titanium nano-coating. Second, the direct drying process after coating application results in inconsistent thickness control and poor quality of the coating. Summary of the Invention

[0004] The purpose of this invention is to provide a production process for brushed black titanium nano-coating for decorative panels in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A manufacturing process for a brushed black titanium nano-coating for decorative panels includes the following steps:

[0007] Step 1: Substrate surface pretreatment. Select a suitable metal substrate, ensure that the surface of the metal substrate is flat and smooth, and use ultrasonic cleaning and mechanical wiping to remove impurities from the surface of the metal substrate. At the same time, polish the surface of the metal substrate.

[0008] Step 2: Substrate drawing. The substrate after surface cleaning and polishing is placed on a continuous conveyor drawing device, and the drawing operation is carried out under the action of the drawing mechanism that can move back and forth on the drawing device.

[0009] Step 3: Smooth the surface of the substrate. After cleaning the surface of the substrate after the wire drawing, grind it smooth and clean the debris on the surface of the substrate again after grinding.

[0010] Step 4: Coating application. Place the smooth substrate after wire drawing into the deposition chamber and apply the black titanium nano-coating to the substrate surface using physical evaporation deposition.

[0011] Step 5: Curing treatment. After the black titanium nano-coating is applied, the substrate is annealed to increase the hardness of the black titanium nano-coating on the substrate surface.

[0012] Step 6: Coating thickness detection and correction. A coating thickness detection instrument is used to detect the coating thickness on the substrate surface, and correction is carried out in a timely manner when the black titanium nano coating thickness on the substrate surface does not meet the standard, so as to ensure that the black titanium nano coating thickness on the substrate surface is uniform.

[0013] Step 7: Surface treatment. Spray a protective coating onto the substrate surface to increase the wear resistance and corrosion resistance of the black titanium nano-coating, thus completing the preparation of the black titanium nano-coating on the substrate surface.

[0014] Furthermore, the mechanical wiping cleaning in step 1 is mainly achieved by using an electric rolling brush. After cleaning, the substrate surface needs to be dried by air blowing. Using mechanical wiping cleaning can prevent the residue floating in the cleaning solution after ultrasonic cleaning from adhering to the substrate surface again.

[0015] Furthermore, in step 1, the substrate is ultrasonically cleaned by immersing it in an ultrasonic cleaning tank, and mechanical wiping is performed after the ultrasonic cleaning process. Ultrasonic cleaning can effectively remove firmly adhered debris from the substrate surface.

[0016] Furthermore, the purpose of polishing in step 3 is to remove the burrs on the surface of the substrate after wire drawing, so as to ensure the adhesion between the surface of the substrate after wire drawing and the subsequently applied black titanium nano-coating.

[0017] Furthermore, in step 5, the annealing temperature is 450℃-650℃. By strictly controlling the annealing temperature, the dimensional stability of the substrate after annealing can be effectively ensured.

[0018] Furthermore, in step 6, if the black titanium nano-coating on the substrate surface is substandard, there are two situations. One situation is that the coating thickness is too large. In this case, the coating thickness can be ensured to be consistent throughout the substrate surface by precision grinding. The other situation is that the coating thickness on the substrate surface is too small. In this case, the substrate needs to be sent back to the physical deposition chamber to apply the black titanium nano-coating to ensure that the black titanium nano-coating thickness on the substrate surface is consistent.

[0019] Furthermore, in step 7, the protective coating is a transparent structure with a thickness of 40-60 μm. Under the action of the protective coating, the service life of the black titanium nano-coating on the substrate surface is significantly improved.

[0020] The beneficial effects of this invention are as follows:

[0021] This invention utilizes a continuous conveying device to automatically feed the substrate during the wire drawing process. Simultaneously, a reciprocating wire drawing mechanism draws the substrate and its inner metal, resulting in a smoother and more continuous feeding and wire drawing process. This facilitates the efficient application of the black titanium nano-coating to the substrate surface. Furthermore, by detecting and correcting the thickness of the black titanium nano-coating after its application, the thickness of the coating on the substrate surface becomes more uniform, leading to better processing quality.

[0024] Step 1: Substrate surface pretreatment. Select a suitable metal substrate, ensure that the surface of the metal substrate is flat and smooth, and use ultrasonic cleaning and mechanical wiping to remove impurities from the surface of the metal substrate. At the same time, polish the surface of the metal substrate.

[0025] Step 2: Substrate drawing. The substrate after surface cleaning and polishing is placed on a continuous conveyor drawing device, and the drawing operation is carried out under the action of the drawing mechanism that can move back and forth on the drawing device.

[0026] Step 3: Smooth the surface of the substrate. After cleaning the surface of the substrate after the wire drawing, grind it smooth and clean the debris on the surface of the substrate again after grinding.

[0027] Step 4: Coating application. Place the smooth substrate after wire drawing into the deposition chamber and apply the black titanium nano-coating to the substrate surface using physical evaporation deposition.

[0028] Step 5: Curing treatment. After the black titanium nano-coating is applied, the substrate is annealed to increase the hardness of the black titanium nano-coating on the substrate surface.

[0029] Step 6: Coating thickness detection and correction. A coating thickness detection instrument is used to detect the coating thickness on the substrate surface, and correction is carried out in a timely manner when the black titanium nano coating thickness on the substrate surface does not meet the standard, so as to ensure that the black titanium nano coating thickness on the substrate surface is uniform.

[0030] Step 7: Surface treatment. Spray a protective coating onto the substrate surface to increase the wear resistance and corrosion resistance of the black titanium nano-coating, thus completing the preparation of the black titanium nano-coating on the substrate surface.

[0031] In this embodiment, the mechanical wiping cleaning in step 1 is mainly achieved by using an electric rolling brush. After cleaning, the substrate surface needs to be dried by air blowing. Using mechanical wiping cleaning can avoid the re-adhesion of the residue floating in the cleaning solution on the substrate surface after ultrasonic cleaning.

[0032] In this embodiment, the ultrasonic cleaning of the substrate in step 1 is achieved by immersing the substrate in an ultrasonic cleaning tank, and mechanical wiping cleaning is performed after the ultrasonic cleaning process. The ultrasonic cleaning method can effectively remove firmly adhered debris from the substrate surface.

[0033] In this embodiment, the purpose of polishing in step 3 is to remove the burrs on the surface of the substrate after wire drawing, so as to ensure the adhesion between the surface of the substrate after wire drawing and the subsequently applied black titanium nano-coating.

[0034] In this embodiment, the annealing temperature in step 5 is 450℃-650℃. By strictly controlling the annealing temperature, the dimensional stability of the substrate after annealing can be effectively ensured.

[0035] In this embodiment, there are two situations where the black titanium nano-coating on the substrate surface does not meet the standard in step 6. One situation is that the coating thickness is too large. In this case, the coating thickness can be ensured to be consistent in all parts of the substrate surface by precision grinding. The other situation is that the coating thickness on the substrate surface is too small. In this case, the substrate needs to be sent back to the physical deposition chamber to apply the black titanium nano-coating to ensure that the black titanium nano-coating thickness on the substrate surface is consistent.

[0036] In this embodiment, the protective coating in step 7 is a transparent structure with a thickness of 40-60 μm. Under the action of the protective coating, the service life of the black titanium nano-coating on the substrate surface is significantly improved.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
