Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber magnets, specifically to high-absorption rubber magnets with good flatness. Background Technology
[0002] Rubber magnets are functional composite materials made from a rubber matrix and magnetic powders (such as ferrite magnetic powder). They possess flexibility, ease of processing, and plasticity, and can be manufactured into products of various shapes and sizes through processes such as injection molding, compression molding, and extrusion. Rubber magnets are divided into two types: isotropic and anisotropic. Isotropic rubber magnets have weaker magnetic properties and are commonly used in advertising, toys, and other fields; anisotropic rubber magnets have stronger magnetic properties and are suitable for magnetic attraction components in complex working environments such as motors and sensors.
[0003] Existing rubber magnets are usually made by mixing magnetic powder with some rubber and then sealing one side. However, rubber magnets made in this way have low bending and stretching capabilities, making them difficult to adapt to different scenarios. In addition, the sealing on both sides is poor, making them prone to adhesion and failure. Utility Model Content
[0004] The purpose of this invention is to provide a high-absorption rubber magnet with good flatness in order to solve the above-mentioned problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A high-absorption rubber magnet with good flatness includes: a magnetic absorption layer, a connecting layer fixedly disposed on the top side of the magnetic absorption layer, two flexible bands fixedly disposed between the magnetic absorption layers, a protective film fixedly disposed on the top side of the connecting layer, a limiting layer fixedly disposed on both sides of the magnetic absorption layer, an anti-corrosion layer fixedly disposed on the opposite side of the two limiting layers, and a connecting sealing layer fixedly disposed on the opposite side of the two anti-corrosion layers.
[0007] Furthermore, the connecting sealing layer is connected to both the anti-corrosion layer and the protective film, with the anti-corrosion layer located below and the protective film located above.
[0008] Furthermore, the connecting sealing layer is L-shaped, with the lower inner side connected to the outer side of the anti-corrosion layer and the upper inner side connected to the outer side of the protective film.
[0009] Furthermore, the magnetic attraction layer is composed of three parts, and the two flexible bands are respectively disposed between the three magnetic attraction layers.
[0010] Furthermore, the connecting layer and the connecting sealing layers on both sides together have the same width as the protective film.
[0011] Furthermore, the flexible band is made of natural rubber, and the connecting layer is made of silicone rubber.
[0012] Furthermore, the material of the connecting sealing layer is polyethylene, and the material of the anti-corrosion layer is a graphene coating.
[0013] Furthermore, the protective film is made of a multilayer soft magnetic composite film made of polymer resin.
[0014] Using the above structure, the magnetic layer is located at the bottom, allowing the product to be directly adhered to the desired position. Two flexible bands positioned inside the magnetic layer not only wrap and clamp the magnetic layer but also improve its overall flexibility, maintaining flatness on the bottom side. A connecting layer limits the order and installation position of the magnetic layer and flexible bands, while also connecting the magnetic layer, flexible bands, and the upper protective film together to form a single unit. The protective film's material properties provide excellent adhesion and protection. After the magnetic layer, flexible bands, connecting layer, and protective film are installed, two limiting layers are sandwiched between the magnetic bands and connecting layer to restrict their position. The anti-corrosion layer prevents the connecting layer and magnetic layer from failing due to external influences. The outermost sealing layer seals both sides of the protective film, improving airtightness, preventing internal air bubbles, and maintaining the product's flatness.
[0015] In summary, the beneficial effects of this utility model are as follows: by using the limiting layer and the connecting sealing layer, the outer side of the connecting layer, the magnetic layer and the protective film are sealed and protected, improving the sealing performance on both sides and preventing gas and other substances from entering the interior and affecting the flatness of the product surface.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] See Figures 1-6 As shown, this utility model provides a high-absorption rubber magnet with good flatness, comprising: a magnetic absorption layer 1, a connecting layer 3 fixedly disposed on the top side of the magnetic absorption layer 1, two flexible bands 2 fixedly disposed between the magnetic absorption layers 1, a protective film 7 fixedly disposed on the top side of the connecting layer 3, a limiting layer 6 fixedly disposed on both sides of the magnetic absorption layer 1, an anti-corrosion layer 5 fixedly disposed on the opposite side of the two limiting layers 6, and a connecting sealing layer 4 fixedly disposed on the opposite side of the two anti-corrosion layers 5;
[0027] Using the above technical solution, the magnetic layer 1 and the two flexible bands 2 are positioned and installed through the connecting layer 3. The magnetic layer 1 is installed and fixed in three positions, with the three magnetic layers 1 separating the inner sides for installing the flexible bands 2. This allows the magnetic layer 1 to clamp the flexible bands 2 on the inner side, enabling the product to adhere to the surface of other objects while maintaining its own toughness to cope with curved surfaces. By using a limiting layer 6 at the outer gap between the magnetic layer 1 and the connecting layer 3, the magnetic layer 1 and the connecting layer 3 are prevented from separating due to external influences, thus affecting the magnetism and overall adhesion. The anti-corrosion layer 5 provides more efficient protection for the outer sides of the connecting layer 3 and the magnetic layer 1. The connecting sealing layer 4 covers and seals the anti-corrosion layer 5 and the protective film 7 above it, further improving the sealing performance and preventing adhesion failure that would reduce flatness.
[0028] See Figures 2-6 As shown, the connecting sealing layer 4 is connected to both the anti-corrosion layer 5 and the protective film 7. The anti-corrosion layer 5 is located at the bottom, and the protective film 7 is located at the top. The connecting sealing layer 4 is L-shaped, with its lower inner side connected to the outer side of the anti-corrosion layer 5 and its upper inner side connected to the outer side of the protective film 7.
[0029] In use, the connecting sealing layer 4 wraps the outside of the anti-corrosion layer 5 and the protective film 7, improving the sealing performance of the outside of the protective film 7 and the anti-corrosion layer 5. Through the integrity of the connecting sealing layer 4, the sealing performance of the inner structure is improved.
[0030] See Figures 1-6 As shown, the magnetic layer 1 is composed of three parts, with two flexible bands 2 respectively disposed between the three magnetic layers 1, and the connecting layer 3 and the connecting sealing layers 4 on both sides together having the same width as the protective film 7.
[0031] In the above embodiment, there are three magnetic layers 1, and the flexible bands 2 are set on the inner side of both sides and the middle, which reduces the content of magnetic layers 1 and improves the overall flexibility, so that the product has better flatness and adaptability to more different angles after installation.
[0032] See Figures 1-6 As shown, the flexible band 2 is made of natural rubber, the connecting layer 3 is made of silicone rubber, the connecting sealing layer 4 is made of polyethylene, the anti-corrosion layer 5 is made of graphene coating, and the protective film 7 is made of a multilayer soft magnetic composite film made of polymer resin.
[0033] In use, the natural rubber used in the flexible band 2 has the property of being able to be made into a magnetorheological elastomer. The natural rubber substrate has high tensile strength and tear strength, making it easier for the bottom side of this product to adhere to different curvatures. The silicone rubber used in the connecting layer 3 has excellent plasticity and ductility, and the addition of magnetic powder makes it magnetic, which is used to increase the attraction of the magnetic layer 1 and improve the attraction of this product. The graphene used in the anti-corrosion layer 5 has high specific surface area, high strength and good conductivity, which can significantly improve the anti-corrosion performance of the coating, especially performing well in acidic environments. The polyethylene used in the connecting sealing layer 4 has strong stability. The multilayer soft magnetic composite film supported by polymer resin used in the protective film 7 has good adhesion and protective performance, and has relatively good toughness, which is used in conjunction with the whole.
[0034] Using the above structure, the magnetic layer 1 is located at the bottom, allowing the product to be directly adhered to the desired position. Two flexible bands 2, positioned between the inner sides of the magnetic layer 1, not only wrap and clamp the magnetic layer 1 but also enhance its overall flexibility, maintaining a flat bottom. A connecting layer 3 limits the sequence and installation position of the magnetic layer 1 and the flexible bands 2. Simultaneously, the connecting layer 3 connects the magnetic layer 1, the flexible bands 2, and the upper protective film together, forming a single unit. The protective film 7 utilizes its own material properties... Its unique properties give it excellent adhesion and protective performance. After the magnetic layer 1, flexible band 2, connecting layer 3, and protective film 7 are installed, two limiting layers 6 are sandwiched between the magnetic layer and the connecting layer 3 on both sides to limit their position. At the same time, the anti-corrosion layer 5 prevents the connecting layer 3 and the magnetic layer 1 from being affected by external factors and thus failing to adhere. Meanwhile, the outermost connecting sealing layer 4 seals both sides of the protective film 7, improving airtightness, preventing internal air bubbles, and maintaining the product's good flatness.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
