Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel plates, in particular to a stainless steel plate with an etched surface. Background Art

[0002] According to the definition in GB / T20878-2007, stainless steel is a steel with corrosion resistance as the main characteristic, and the chromium content is at least 10.5%, and the maximum carbon content does not exceed 1.2%.

[0003] Etching is a common processing method for stainless steel. Through etching, the process of precisely controlling the tiny details on the metal surface can be achieved, making the metal surface very smooth, and very fine shapes and patterns can be processed. If stainless steel is applied in the electronic field, for example, when manufacturing precision components such as microelectronic components and sensors, stainless steel sheets need to be etched to manufacture very fine metal structures. In these scenarios, stainless steel sheet etching can better meet these requirements because of its very high processing precision and can manufacture more refined metal structures. However, due to the relatively fine etched structure, this structure is prone to wear, and at the same time, it is easily corroded by acids and alkalis, resulting in changes in the structure, making the structure inapplicable to the corresponding electronic components. Therefore, it is necessary to improve the existing etched stainless steel. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies of the existing technology, the main purpose of the utility model is to provide a stainless steel plate with an etched surface, which can effectively solve the problem that the structure formed by etching the existing etched stainless steel is prone to wear and structure changes due to acid and alkali corrosion.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A stainless steel plate with an etched surface includes a stainless steel body, an anti-corrosion layer, a heat-insulating layer, and a wear-resistant layer; at least one surface of the stainless steel body is formed with an etched surface by etching, and the etched surface has a structure adapted to the corresponding electronic components or forms a very fine shape or pattern, which varies according to different application fields and products; the anti-corrosion layer is formed on the etched surface; the heat-insulating layer is coated on the surface of the anti-corrosion layer, and the wear-resistant layer is coated on the surface of the heat-insulating layer.

[0007] As a preferred solution, both surfaces of the stainless steel body are formed with etched surfaces by etching. Correspondingly, there are two anti-corrosion layers, two heat-insulating layers, and two wear-resistant layers. The two anti-corrosion layers are respectively formed on the corresponding etched surfaces, the two heat-insulating layers are respectively coated on the surfaces of the corresponding anti-corrosion layers, and the two wear-resistant layers are respectively coated on the surfaces of the corresponding heat-insulating layers.

[0008] As a preferred solution, the anti-corrosion layer is a tin plating layer, which is formed on the etched surface by electroplating. The tin plating layer can greatly reduce the thickness of the anti-corrosion layer, so that the thickness of the stainless steel in the plate can be as thick as possible to ensure the strength of the plate.

[0009] As a preferred solution, the heat insulation layer is made of polystyrene resin. Although covering the anti-corrosion layer can isolate most of the air, air can still penetrate through the resin structure, even if the amount of air penetrating is very small. The design of the heat insulation layer is to prevent the anti-corrosion layer from undergoing an oxidation reaction with air at a relatively high temperature, resulting in the anti-corrosion layer losing its anti-corrosion function.

[0010] As a preferred solution, the wear-resistant layer is made of PVDF material. PVDF has very good wear resistance and can protect the heat insulation layer, the anti-corrosion layer, and the etched surface from being worn.

[0011] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0012] By forming an anti-corrosion layer on the etched surface and then coating the wear-resistant layer on the surface of the heat insulation layer, the plate has excellent anti-corrosion function and wear resistance. The various structures or patterns formed on the etched surface will not change due to corrosion and will not be worn.

[0013] To more clearly illustrate the structural features and functions of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments: Description of the Drawings

[0017] 20. Anti-corrosion layer 30. Heat insulation layer

[0018] 40. Wear-resistant layer. Detailed Embodiment

[0019] Please refer to Figure 1 as shown, which shows the specific structure of a preferred embodiment of the present utility model, including a stainless steel body 10, an anti-corrosion layer 20, a heat insulation layer 30, and a wear-resistant layer 40.

[0020] At least one surface of the stainless steel body 10 is formed with an etched surface 11 by etching. The etched surface 11 has structures adapted to corresponding electronic components or forms very fine shapes or patterns, which vary according to different application fields and products.

[0021] The anti-corrosion layer 20 is formed on the etched surface 11; in this embodiment, the anti-corrosion layer 20 is a tin plating layer, and the tin plating layer is formed on the etched surface 11 by electroplating. Compared with the traditional anti-corrosion layer, the tin plating layer can greatly reduce the thickness of the anti-corrosion layer 20, so that the thickness of the stainless steel in the plate can be as thick as possible to ensure the strength of the plate.

[0022] The heat insulation layer 30 is coated on the surface of the anti-corrosion layer 20; in this embodiment, the heat insulation layer 30 is made of polystyrene resin. Although covering a film on the anti-corrosion layer 20 can isolate most of the air, air can still penetrate through the resin structure, even if the amount of air penetrating is very small. The design of the heat insulation layer 30 is to prevent the anti-corrosion layer 20 from undergoing an oxidation reaction with air at a relatively high temperature, resulting in the anti-corrosion layer 20 losing its anti-corrosion function.

[0023] The wear-resistant layer 40 is coated on the surface of the heat insulation layer 30; in this embodiment, the wear-resistant layer 40 is made of PVDF material. PVDF has very good wear resistance and can protect the heat insulation layer 30, the anti-corrosion layer 20, and the etched surface 11 from being worn.

[0024] Specifically, etched surfaces 11 are formed on both surfaces of the stainless steel body 10 by etching. Correspondingly, there are two anti-corrosion layers 20, two heat insulation layers 30, and two wear-resistant layers 40. The two anti-corrosion layers 20 are respectively formed on the corresponding etched surfaces 11, the two heat insulation layers 30 are respectively coated on the surfaces of the corresponding anti-corrosion layers 20, and the two wear-resistant layers 40 are respectively coated on the surfaces of the corresponding heat insulation layers 30.

[0025] The design focus of the present utility model lies in: by forming an anti-corrosion layer on the etched surface and then coating a wear-resistant layer on the surface of the heat insulation layer, the plate has excellent anti-corrosion function and wear resistance, and various structures or patterns formed on the etched surface will not change due to corrosion and will not be worn.

[0026] The above description is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
