Description

Technical Field

[0001] The invention relates to the technical field, and in particular to a production process of a brushed black titanium nano coating for a decorative plate. Background Art

[0002] Brushed black titanium nano coating is a special coating applied to metal surfaces with unique appearance and performance characteristics. It is often used to decorate and enhance the visual appeal and durability of products. In the production process of metal decorative sheets, black titanium nano coating is applied to the surface of metal sheets to protect the surface of metal decorative sheets.

[0003] At present, the general process flow of applying black titanium nano-coating on the surface of metal substrates is: substrate preparation, wire drawing, cleaning and pretreatment, coating application and drying. Although the black titanium nano-coating can be applied to the surface of the device plate under the above processing technology, on the one hand, when the substrate is wired during the processing, the above process mainly relies on the wire drawing equipment when it is fixed to draw the substrate. Since the feeding and replacement process of the substrate during the wire drawing process is relatively cumbersome, the entire wire drawing process of the substrate is time-consuming, which is not convenient for the efficient application of the black titanium nano-coating on the substrate. On the other hand, after the black titanium nano-coating is applied, the above process directly dries the substrate, resulting in the application thickness of the black titanium nano-coating on the substrate cannot be accurately controlled, resulting in poor processing quality of the black titanium nano-coating on the substrate. Summary of the invention

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

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A production process of a brushed black titanium nano coating for a decorative plate comprises the following steps:

[0007] Step 1: Pre-treat the surface of the substrate. Select a suitable metal substrate to ensure that the surface of the metal substrate is smooth and clean. Use ultrasonic cleaning and mechanical wiping cleaning to remove impurities on the surface of the metal substrate, and polish the surface of the metal substrate.

[0008] Step 2: Wire drawing of the substrate, placing the substrate after surface cleaning and polishing on a continuous conveying wire drawing device, and performing the wire drawing operation under the action of a wire drawing mechanism capable of moving back and forth on the wire drawing device;

[0009] Step 3: The surface of the substrate is flat. The surface of the substrate after wire drawing is cleaned and then polished to make it flat, and the debris on the surface of the substrate after polishing is cleaned again;

[0010] Step 4: Applying the coating, placing the substrate with a flat surface after drawing in a deposition chamber, and applying the black titanium nano-coating on the surface of the substrate by 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 after it is applied on the surface of the substrate;

[0012] Step 6: Coating thickness detection and correction: Use a coating thickness detection instrument to detect the coating thickness on the substrate surface, and make corrections in time when the thickness of the black titanium nano coating on the substrate surface does not meet the standard to ensure that the thickness of the black titanium nano coating on the substrate surface is uniform;

[0013] Step 7: Surface treatment: spray a protective coating on the surface of the substrate to which the black titanium nano coating is applied to increase the wear resistance and corrosion resistance of the black titanium nano coating, thereby completing the application and preparation of the black titanium nano coating on the surface of the substrate.

[0014] Furthermore, the mechanical wiping cleaning in step 1 is mainly achieved by using an electric rolling brush, and the substrate surface needs to be blown dry after cleaning. Mechanical wiping cleaning can avoid the re-adhesion of floating residues in the cleaning solution after ultrasonic cleaning to the substrate surface.

[0015] Furthermore, in step 1, ultrasonic cleaning of the substrate is performed by placing the substrate into an ultrasonic cleaning tank, and mechanical wiping cleaning is performed after the ultrasonic cleaning process. Ultrasonic cleaning can effectively remove debris that is firmly adhered to the surface of the substrate.

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

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

[0018] Furthermore, in step 6, there are two situations in which the black titanium nano-coating on the surface of the substrate does not meet the standard. One is that the coating thickness is too large. In this case, the coating thickness at various locations on the surface of the substrate can be ensured to be consistent only by precision grinding. The other is that the coating thickness on the surface of the substrate is too small. In this case, the substrate needs to be returned to the physical deposition chamber for application of the black titanium nano-coating to ensure that the thickness of the black titanium nano-coating on the surface of the substrate is consistent.

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

[0020] The beneficial effects of the present invention are:

[0021] The present invention uses a continuous conveying device to realize automatic conveying of the substrate when drawing the substrate, and at the same time cooperates with a wire drawing mechanism that moves back and forth to draw the substrate and Xining, so that the entire feeding and drawing process of the substrate is smoother and more continuous, thereby facilitating the subsequent efficient application of the black titanium nano coating on the surface of the substrate. At the same time, by detecting and correcting the thickness of the black titanium nano coating after applying the black titanium nano coating on the substrate, the thickness of the black titanium nano coating on the surface of the substrate is more uniform and the processing quality is better.

[0023] A production process of a brushed black titanium nano coating for a decorative plate comprises the following steps:

[0024] Step 1: Pre-treat the surface of the substrate. Select a suitable metal substrate to ensure that the surface of the metal substrate is smooth and clean. Use ultrasonic cleaning and mechanical wiping cleaning to remove impurities on the surface of the metal substrate, and polish the surface of the metal substrate.

[0025] Step 2: Wire drawing of the substrate, placing the substrate after surface cleaning and polishing on a continuous conveying wire drawing device, and performing the wire drawing operation under the action of a wire drawing mechanism capable of moving back and forth on the wire drawing device;

[0026] Step 3: The surface of the substrate is flat. The surface of the substrate after wire drawing is cleaned and then polished to make it flat, and the debris on the surface of the substrate after polishing is cleaned again;

[0027] Step 4: Applying the coating, placing the substrate with a flat surface after drawing in a deposition chamber, and applying the black titanium nano-coating on the surface of the substrate by 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 after it is applied on the surface of the substrate;

[0029] Step 6: Coating thickness detection and correction: Use a coating thickness detection instrument to detect the coating thickness on the substrate surface, and make corrections in time when the thickness of the black titanium nano coating on the substrate surface does not meet the standard to ensure that the thickness of the black titanium nano coating on the substrate surface is uniform;

[0030] Step 7: Surface treatment: spray a protective coating on the surface of the substrate to which the black titanium nano coating is applied to increase the wear resistance and corrosion resistance of the black titanium nano coating, thereby completing the application and preparation of the black titanium nano coating on the surface of the substrate.

[0031] In this embodiment, the mechanical wiping cleaning in step 1 is mainly achieved by using an electric rolling brush, and the substrate surface needs to be blown dry after cleaning. Mechanical wiping cleaning can avoid the re-adhesion of floating residues in the cleaning liquid after ultrasonic cleaning to the substrate surface.

[0032] In this embodiment, in step 1, ultrasonic cleaning of the substrate is performed by placing the substrate into an ultrasonic cleaning tank, and mechanical wiping cleaning is performed after the ultrasonic cleaning process. Ultrasonic cleaning can effectively remove debris that is firmly adhered to the surface of the substrate.

[0033] In this embodiment, the purpose of grinding in step 3 is to remove burrs on the surface of the substrate after wire drawing and ensure the adhesion strength 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° C.-650° C. 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 in which the black titanium nano-coating on the surface of the substrate in step 6 does not meet the standards. One is that the coating thickness is too large. In this case, the coating thickness at various locations on the substrate surface can be ensured to be consistent only by precision grinding. The other is that the coating thickness on the substrate surface is too small. In this case, the substrate needs to be returned to the physical deposition chamber for application of the black titanium nano-coating to ensure that the thickness of the black titanium nano-coating on the substrate surface is consistent.

[0036] In this embodiment, the protective coating in step 7 is a transparent structure, and the thickness of the protective coating is 40-60 μm. Under the action of the protective coating, the service life of the black titanium nano coating on the surface of the substrate 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
