Stain-resistant stainless steel sheet

Abstract

This application discloses a stain-resistant stainless steel sheet, comprising a substrate. The outer surface of the substrate is sequentially coated from the inside out with an inner plasma layer, a superhydrophobic and oleophobic underlayer, and a superhydrophobic and oleophobic surface layer. The inner surface of the substrate is sequentially coated from the inside out with an inner second plasma layer, an antistatic coating, and a high-temperature resistant coating. This application, by coating the inner first and inner second plasma layers onto the inner and outer surfaces of the substrate respectively, not only effectively cleans the substrate but also enhances the adhesion between the substrate and subsequent coatings. Subsequently, the superhydrophobic and oleophobic underlayer and the superhydrophobic and oleophobic surface layer work together to give the stainless steel sheet excellent hydrophobic and oleophobic properties. The superhydrophobic surface has an extremely high water contact angle, causing water droplets to form spherical shapes on the surface, easily rolling off and carrying away surface dirt and oil. This characteristic significantly reduces the probability of dirt adhesion, keeping the sheet surface clean and reducing the frequency and cost of cleaning and maintenance.

Description

Technical Field

[0001] This application relates to the technical field of stainless steel sheets, and more particularly to a stain-resistant stainless steel sheet. Background Technology

[0002] Stainless steel sheets are widely used in various fields due to their advantages such as corrosion resistance, high strength, and ease of cleaning, including rice cooker shells, food processor shells, refrigerator shells, and elevator interior panels. However, in actual use, the surface of stainless steel sheets is easily stained with dirt such as fingerprints, oil stains, and water stains. These stains are not only difficult to remove but also significantly affect the aesthetics of the product. Therefore, those skilled in the art urgently need to develop a stain-resistant stainless steel sheet to meet the needs of practical applications. Utility Model Content

[0003] The main objective of this application is to provide a stain-resistant stainless steel sheet, which aims to solve the aforementioned technical problems.

[0004] A stain-resistant stainless steel sheet includes a substrate. The outer surface of the substrate is provided with an inner plasma layer, a superhydrophobic and oleophobic bottom layer, and a superhydrophobic and oleophobic surface layer from the inside out. The inner surface of the substrate is provided with an inner second plasma layer, an antistatic coating, and a high-temperature resistant coating from the inside out.

[0005] As described above, the roughness range of the inner first plasma layer and the inner second plasma layer of the stain-resistant stainless steel plate is 50-100 μm.

[0006] The thickness of the superhydrophobic and oleophobic substrate in the aforementioned stain-resistant stainless steel sheet ranges from 10 to 25 μm.

[0007] The thickness of the superhydrophobic and oleophobic surface layer of the aforementioned stain-resistant stainless steel sheet ranges from 10 to 25 μm.

[0008] As described above, the antistatic coating of the stain-resistant stainless steel plate is applied using an antistatic paint, and its thickness ranges from 10 to 20 μm.

[0009] The stain-resistant stainless steel plate described above has a high-temperature resistant coating made of silicone high-temperature resistant paint, and its thickness ranges from 10 to 30 μm.

[0010] As described above, the stain-resistant stainless steel plate is further provided with an outer protective film layer located outside the superhydrophobic and oleophobic surface layer, and an outer second protective film layer located outside the high-temperature resistant coating.

[0011] As described above, the first and second outer protective films of the stain-resistant stainless steel sheet are both PE films with a thickness ranging from 50 to 100 μm.

[0012] Compared with the prior art, the above application has the following advantages:

[0013] 1. The stain-resistant stainless steel sheet of this application is coated with an inner plasma layer and an inner plasma layer on the inner and outer surfaces of the substrate, respectively. This not only effectively cleans the substrate but also enhances the adhesion between the substrate and subsequent coatings. Furthermore, the superhydrophobic and oleophobic underlayer and the superhydrophobic and oleophobic surface layer work together to give the stainless steel sheet excellent hydrophobic and oleophobic properties. The superhydrophobic surface has an extremely high water contact angle, causing water droplets to form spherical shapes on the surface and easily roll off, carrying away surface dirt and oil. This characteristic significantly reduces the probability of dirt adhesion, keeping the sheet surface clean and reducing the frequency and cost of cleaning and maintenance.

[0014] 2. The antistatic coating of this application effectively prevents the accumulation of static electricity, which not only avoids the adhesion of dust and particles caused by static adsorption, but also effectively prevents static electric shock. The high-temperature resistant coating ensures that the stainless steel plate can maintain its physical and chemical properties in high-temperature environments without deformation, degradation or damage. This makes the stainless steel plate suitable for use in high-temperature environments, such as the interior of ovens.

[0015] 3. The stain-resistant stainless steel sheet of this application, through its carefully designed multi-layer structure, not only possesses excellent stain resistance but also integrates antistatic and high-temperature resistance functions, making it widely applicable in various industrial and commercial applications. Attached Figure Description

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0019] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0020] like Figure 1 As shown, a stain-resistant stainless steel plate includes a substrate 1. The outer surface of the substrate 1 is provided with an inner plasma layer 2, a superhydrophobic and oleophobic bottom layer 3, and a superhydrophobic and oleophobic surface layer 4 from the inside out. The inner surface of the substrate 1 is provided with an inner second plasma layer 5, an antistatic coating 6, and a high-temperature resistant coating 7 from the inside out.

[0021] This application's stain-resistant stainless steel sheet utilizes an inner plasma layer 2 and an inner plasma layer 5 coated on the inner and outer surfaces of the substrate 1, respectively. This not only effectively cleans the substrate 1 but also enhances the adhesion between the substrate 1 and subsequent coatings. Furthermore, the superhydrophobic and oleophobic underlayer 3 and the superhydrophobic and oleophobic surface layer 4 work together to impart excellent hydrophobic and oleophobic properties to the stainless steel sheet. The superhydrophobic surface has an extremely high water contact angle (greater than 150°), causing water droplets to form spherical shapes on the surface, easily rolling off and carrying away surface dirt and oil. This characteristic significantly reduces the probability of dirt adhesion, keeping the sheet surface clean and reducing the frequency and cost of cleaning and maintenance.

[0022] This application effectively prevents the accumulation of static electricity through the antistatic coating 6, which not only avoids the adhesion of dust and particles caused by static adsorption, but also effectively prevents static electric shock; while the high-temperature resistant coating 7 ensures that the stainless steel plate can maintain its physical and chemical properties in high-temperature environments without deformation, degradation or damage, which makes the stainless steel plate suitable for high-temperature environments, such as the interior of ovens.

[0023] The stain-resistant stainless steel sheet of this application, through its carefully designed multi-layer structure, not only possesses excellent stain resistance but also integrates antistatic and high-temperature resistance functions, making it widely applicable in various industrial and commercial applications.

[0024] Furthermore, the roughness range of both the inner first plasma layer 2 and the inner second plasma layer 5 is 50–100 μm.

[0025] Furthermore, the superhydrophobic and oleophobic underlayer 3 is sprayed with an ultra-clean self-drying nano-coating primer produced by Guangzhou Xisenmeike New Material Technology Co., Ltd., and its thickness ranges from 10 to 25 μm.

[0026] Furthermore, the superhydrophobic and oleophobic surface layer 4 is sprayed with an ultra-clean self-drying nano-coating surface coating produced by Guangzhou Xisenmeike New Material Technology Co., Ltd., and its thickness ranges from 10 to 25 μm.

[0027] Furthermore, the antistatic coating 6 is applied using an antistatic paint, and its thickness ranges from 10 to 20 μm, preferably 15 μm. Its advantage is that it gives the stainless steel plate obvious antistatic effect, wear resistance and other outstanding characteristics, and can be used to shield electromagnetic waves and eliminate static electricity.

[0028] Furthermore, the high-temperature resistant coating 7 is applied using an organosilicon high-temperature resistant coating, and its thickness ranges from 10 to 30 μm, preferably 12 μm. Its advantage is that it improves the high-temperature resistance of this application, so that this application can be applied to high-temperature environments of 250 to 800°C.

[0029] Furthermore, the substrate 1 is also provided with an outer protective film layer 8 located outside the superhydrophobic and oleophobic surface layer 4, and an outer second protective film layer 9 located outside the high-temperature resistant coating 7.

[0030] Both the outer protective film layer 8 and the outer second protective film layer 9 are PE films, and their thickness ranges from 50 to 100 μm. A thickness of 50 μm has the advantage of protecting the present application from contamination, corrosion, and scratches during transportation, storage, and processing.

[0031] The above description is one implementation method provided in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to or identical to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
