Technical Field

[0001] This utility model relates to the field of nail art technology, and in particular to a nail art decoration. Background Technology

[0002] In the field of nail art technology, a wide variety of nail art products are constantly emerging, greatly enriching consumers' choices for beautiful nail decoration. These include wearable nail products as well as magnetic cat-eye and magnetic textured nail products.

[0003] These nail decoration products satisfy users' desire for diverse nail styles to some extent, but they generally have significant shortcomings in terms of ease of use. Specifically, whether it is wearable nail products or magnetic cat-eye / textured nail products, users need to perform a series of operations such as trimming their own nails, adjusting them to fit the decoration product, and applying glue when they want to change their nail style.

[0004] However, the above-mentioned procedures not only make it extremely inconvenient for users to change their nail decorations, wasting a lot of time and energy, but also increase the risk of damage to the nails due to repeated trimming and applying glue during multiple changes. Furthermore, the frequent changes of glue and tools, as well as potential damage to the decorations due to improper handling, also result in relatively high user costs.

[0005] Therefore, the current shortcomings of nail decoration products in terms of ease of wear and cost control have become technical problems that urgently need to be solved in this field. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a nail art decoration to solve the technical problems of poor wearing convenience and high use cost of nail decoration products in the prior art.

[0007] To achieve the above objectives, this application provides the following technical solution: This application provides a nail art decoration, which includes: A base coat layer for application onto the nail, the base coat layer comprising a base coat and ferromagnetic metal powder doped within the base coat; A flexible adsorption layer, magnetically connected to the base adhesive layer, includes an elastomer matrix and a magnetic material doped in the elastomer matrix; A decorative layer is disposed on the side of the flexible adsorption layer opposite to the base adhesive layer.

[0008] According to some embodiments of this application, the base layer contains 50-70 wt% ferromagnetic metal powder, based on the total mass of the base layer.

[0009] According to some embodiments of this application, the ferromagnetic metal powder satisfies x99 < 200 μm.

[0010] According to some embodiments of this application, the ferromagnetic metal powder includes at least one of iron powder, cobalt powder, and iron-silicon-aluminum powder.

[0011] According to some embodiments of this application, the ferromagnetic metal powder is coated with an aluminum oxide coating layer on its outer side; Alternatively, the ferromagnetic metal powder may be coated with an epoxy resin coating on its outer side.

[0012] According to some embodiments of this application, the thickness of the flexible adsorption layer is ≤1mm.

[0013] According to some embodiments of this application, the magnetic material includes at least one of samarium iron nitrogen magnetic powder, neodymium iron nitrogen magnetic powder, neodymium iron boron magnetic powder, and ferrite magnetic powder.

[0014] According to some embodiments of this application, the surface magnetic field strength of the flexible adsorption layer facing the first side of the base adhesive layer is ≥1000Gs; the surface magnetic field strength of the flexible adsorption layer facing away from the base adhesive layer is ≤150Gs.

[0015] According to some embodiments of this application, the flexible adsorption layer extends towards the base adhesive layer on two opposite sides in its width direction to form a concave arc-shaped surface on the first surface and a convex arc-shaped surface on the second surface.

[0016] According to some embodiments of this application, the decorative layer includes a wearable armor, which is bonded to the flexible absorbent layer.

[0017] The above technical solution provides a nail art decoration that features a synergistic design of the base coat layer, flexible adsorption layer, and decorative layer, achieving multiple superior effects. The ferromagnetic metal powder incorporated into the base coat layer forms a stable magnetic adsorption effect with the magnetic material in the flexible adsorption layer, allowing for quick and easy fixing of the decoration without the need for traditional glue. This not only simplifies the nail art process but also avoids damage to the nails caused by glue residue, significantly improving ease of use and safety. Attached Figure Description

[0024] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following embodiments and implementation methods can be combined with each other.

[0025] An exemplary embodiment of this utility model provides a nail art decoration, such as... Figures 1-4 As shown, Figure 1 This is a schematic diagram illustrating the application of nail art decorations to nails according to an exemplary embodiment. Figure 2 This is an exploded view showing the nail art decoration separated from the nail according to an exemplary embodiment. Figure 3 This is a schematic diagram illustrating a base coat layer and a nail according to an exemplary embodiment. Figure 4 This is a schematic diagram illustrating a flexible adhesive layer and a decorative layer according to an exemplary embodiment. The nail art decoration 20 includes: a base coat layer 201, a flexible adhesive layer 202, and a decorative layer 203.

[0026] like Figure 2As shown, the base coat layer 201 corresponds to the bottom layer of the nail art decoration 20, which can be applied to the user's nail 101. It can be understood as a layer of nail polish. The base coat layer 201 includes a base coat 2011 and ferromagnetic metal powder 2012 doped within the base coat 2011. The flexible adsorption layer 202 corresponds to the middle layer of the nail art decoration 20, which can be magnetically connected to the base coat layer 201, enabling a detachable connection between the two. The flexible adsorption layer 202 includes an elastomer matrix 2021 and magnetic material 2022 doped within the elastomer matrix 2021. The decorative layer 203 corresponds to the outer layer of the nail art decoration 20, and is disposed on the side of the flexible adsorption layer 202 that faces away from the base coat layer 201. It can be understood as the outer surface of the nail art decoration 20.

[0027] In this exemplary embodiment, the nail art decoration 20 achieves multiple superior effects through the synergistic design of the base layer 201, the flexible adsorption layer 202, and the decorative layer 203. The ferromagnetic metal powder 2012 doped in the base layer 201 can form a stable magnetic adsorption effect with the magnetic material 2022 in the flexible adsorption layer 202, allowing for quick and easy fixation of the decoration without the need for traditional glue. This not only simplifies the nail art operation and style change process but also avoids damage to the nail 101 caused by glue residue, significantly improving ease of use and safety.

[0028] The flexible adsorption layer 202 uses an elastomer matrix 2021, which is relatively thin and can adaptively deform to conform to the curvature of the nail surface 101, ensuring a tight fit with the base coat layer 201. This effectively reduces problems such as edge lifting and detachment of the nail art, extending the lifespan of the nail art 20. Meanwhile, the decorative layer 203 is located on the side of the flexible adsorption layer 202 facing away from the base coat layer 201. This ensures the complete presentation of visual effects such as decorative patterns and colors, while also reducing the impact of external forces on the nail art during daily activities and maintaining the stability of the decorative effect through the cushioning effect of the flexible adsorption layer 202.

[0029] In addition, the magnetic adsorption structure allows the accessories to be repeatedly disassembled and replaced, enabling users to flexibly switch decorative styles according to different occasions and clothing combinations. This greatly enhances the reusability and personalized experience of the product, satisfying aesthetic needs while also taking into account the protection of nails and ease of use.

[0030] In some exemplary embodiments, the primer layer 201 contains 50-70 wt% ferromagnetic metal powder 2012, based on the total mass of the primer layer 201.

[0031] In this embodiment, by optimizing the content of ferromagnetic metal powder 2012, the mass ratio of ferromagnetic metal powder 2012 in the base adhesive layer 201 is controlled between 50% and 70%, which not only avoids waste of ferromagnetic metal powder 2012, but also takes into account the "magnetism" and "adhesion" of the base adhesive layer 201.

[0032] Specifically, ferromagnetic metal powder 2012 is the core component for the base adhesive layer 201 to achieve magnetic attraction with the flexible adsorption layer 202. The lower limit of 50wt% ferromagnetic metal powder 2012 ensures that an effective "magnetic pathway" can be formed between the powder particles. When the powder content is lower than this value, the particles are too sparsely dispersed, and the magnetism will be greatly weakened due to the "magnetic leakage" phenomenon, which cannot meet the basic functional requirements such as adsorption. The upper limit of 70wt% ferromagnetic metal powder 2012 avoids the phenomenon of insufficient flexibility and poor magnetic powder adhesion caused by too little base adhesive.

[0033] At the same time, this range is compatible with the characteristics of most conventional ferromagnetic powders (such as iron powder, iron-silicon-aluminum powder, etc.). Taking iron powder as an example, at around 60wt%, it can achieve the surface magnetic induction intensity required for conventional applications without performance redundancy due to magnetic saturation caused by particle accumulation.

[0034] The basic properties of the primer layer 201, such as film-forming properties and adhesion, depend on the continuous phase structure of the matrix resin (such as epoxy resin, acrylic resin, etc.). A powder ratio of 50-70 wt% ferromagnetic metal powder 2012 allows the resin phase to uniformly coat the powder particles and form a complete continuous film. The resin acts as a "binder" filling the gaps between the powder particles, ensuring the integrity of the primer layer 201 film formation (avoiding cracking and powder shedding due to excessive powder) while maintaining a certain degree of flexibility to meet the requirements of slight deformation in normal use.

[0035] If the proportion of ferromagnetic metal powder 2012 exceeds 70 wt%, the resin phase will be squeezed into discontinuous "islands", resulting in increased brittleness and decreased adhesion of the base adhesive layer 201; while when it is below 50 wt%, although the resin phase is sufficient, the magnetic properties are insufficient, and the hardness and wear resistance of the adhesive layer will also decrease.

[0036] Furthermore, the 50-70 wt% proportion of ferromagnetic metal powder 2012 makes the rheological properties of the primer layer 201 easier to control. During the coating process, the primer layer 201 needs to have a certain degree of fluidity to ensure uniform molding: too high a proportion of ferromagnetic metal powder 2012 will cause the system viscosity to spike, resulting in "drag marks" during coating or incomplete filling during injection molding; too low a proportion of ferromagnetic metal powder 2012 will result in insufficient viscosity, easily causing "sagging" when applied to vertical surfaces. The viscosity of the primer layer 201 within this range is more suitable for coating nail 101.

[0037] In some exemplary embodiments, the ferromagnetic metal powder 2012 satisfies x99 < 200 μm, that is, in this batch of particulate matter, 99% of the particles have a diameter (or equivalent particle size) of less than 200 micrometers, and only no more than 1% of the particles may be greater than or equal to 200 micrometers.

[0038] In this embodiment, optimizing the particle size of the ferromagnetic metal powder 2012 ensures the fineness of the magnetic base layer. The smaller the particle size (and 99% of them are less than 200μm), the more uniform the force is in the magnetic field, and the more tightly they are arranged, avoiding a grainy feel and ensuring seamless adsorption. If the particles are too large, it will not only be detrimental to the uniform distribution of the ferromagnetic metal powder 2012 in the base layer 2011, but will also cause the base layer 201 to lose its delicate feel.

[0039] Optimizing the particle size of the ferromagnetic metal powder 2012 improves the application performance of nail polish. Specifically, the smaller particles not only disperse better in the nail polish base, making the texture smoother and eliminating noticeable graininess during application, which is ideal for creating a smooth base color, but also reduce the risk of sedimentation, extend the storage stability of the nail polish, and avoid the hassle of repeated stirring before use.

[0040] Optimizing the particle size of the ferromagnetic metal powder 2012 further enhances the adhesion between the base coat 201 and the nail polish 101. Smaller particles have a larger surface area, resulting in a stronger bond with the resin and adhesives in the nail polish. This makes it less prone to peeling off due to daily friction, extending the duration of the manicure. Simultaneously, the finer particles create a thinner and more even coating, preventing the nail polish 101 from appearing heavy.

[0041] Optimizing the particle size of ferromagnetic metal powder 2012 allows for compatibility with a variety of nail polish formulations. This particle size is more adaptable to the base materials of base coat 2011 (such as acrylates, nitrocellulose, etc.), and can be used in both high-viscosity gel polishes and regular nail polishes with good flowability, thus expanding the product formulation design space.

[0042] In some exemplary embodiments, the ferromagnetic metal powder 2012 includes at least one of iron powder, cobalt powder, and iron-silicon-aluminum powder.

[0043] It should be noted that, whether pure metallic ferromagnetic powders such as iron powder are chosen, or iron-based alloy powders such as iron-silicon-aluminum powder are chosen, the amount and type can be matched according to the specific requirements of the scenario for magnetic strength, stability, cost, etc., which will not be elaborated here.

[0044] In some exemplary embodiments, the ferromagnetic metal powder 2012 is coated with an aluminum oxide coating layer.

[0045] In this embodiment, by providing an aluminum oxide coating layer on the outside of the ferromagnetic metal powder 2012, the overall performance of the nail art decoration 20 can be further improved. Specifically, this coating method can effectively isolate the ferromagnetic metal powder 2012 from contact with the external environment, preventing its magnetic attenuation due to oxidation or moisture, ensuring the long-term stability of the magnetic adsorption force between the base layer 201 and the flexible adsorption layer 202, and extending the effective service life of the product.

[0046] When coating the outer surface of ferromagnetic metal powder 2012 with an alumina coating layer, it can be prepared by the sol-gel method: the ferromagnetic metal powder 2012 is dispersed in an aluminum salt solution, the pH value is adjusted to hydrolyze aluminum ions to generate an alumina sol, which is uniformly coated on the powder surface, and then dried and calcined to form a dense alumina film.

[0047] In an alternative to "ferromagnetic metal powder 2012 coated with an alumina coating", an epoxy resin coating may be applied to the outside of the ferromagnetic metal powder 2012.

[0048] The method of "coating the outer side of the ferromagnetic metal powder 2012 with an epoxy resin coating" can not only effectively isolate the ferromagnetic metal powder 2012 from contact with the external environment, preventing it from losing its magnetic properties due to oxidation, rust, or moisture, thus ensuring the long-term stability of the magnetic adsorption force between the base layer 201 and the flexible adsorption layer 202 and extending the effective service life of the product, but also reduce the impact of the metal powder on the colloidal stability of the base layer 201, preventing problems such as delamination and abnormal curing of the base layer 2011, and ensuring the uniformity and adhesion of the base layer 201 during coating.

[0049] When coating the outer side of ferromagnetic metal powder 2012 with epoxy resin, the immersion method can be used: immerse the ferromagnetic metal powder 2012 in an epoxy resin solution, stir to make the powder surface uniformly coated with a layer of resin, and then perform ultraviolet curing or heat curing treatment to form a protective coating with a certain toughness. It should be noted that both of the above methods are simple to operate and can be used to process metal powders in batches, making them suitable for industrial production. In some exemplary embodiments, considering the overall aesthetics and user experience of the nail art decoration 20, the nail art decoration 20 should not be too thick overall, and the thickness of the flexible adsorption layer 202 can be optimized. For example, the thickness of the flexible adsorption layer 202 is ≤1mm.

[0050] In some exemplary embodiments, the elastomer matrix 2021 may be made of thermoplastic elastomers or rubber-like materials, such as styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, diene-based thermoplastic elastomers, urethane-based thermoplastic elastomers, etc., to impart good tensile, bending and other elastic properties to the material.

[0051] The elastomer matrix 2021 gives the material good elasticity and flexibility, allowing it to be bent, twisted, and stretched without breaking. It can adapt to various complex shapes and dynamic deformation applications, such as products as thin as 0.1mm in strip, sheet, and ring shapes.

[0052] Alternatively, based on the plasticity of the elastomer matrix 2021, the flexible adsorption layer 202 is designed to be within 0.5mm to further reduce the overall thickness of the nail art decoration 20.

[0053] In some exemplary embodiments, such as Figure 2 As shown, the magnetic material 2022 can be constructed as magnetic powder. Optionally, the magnetic material includes at least one of samarium iron nitride magnetic powder, neodymium iron nitride magnetic powder, neodymium iron boron magnetic powder, and ferrite magnetic powder.

[0054] Because the flexible adsorption layer 202 contains magnetic material 2022, which has characteristics such as high remanence, high coercivity, and high energy product, it can generate a strong magnetic field within a small volume, meeting the needs of various magnetic applications. Based on the magnetic properties of the magnetic material 2022, the flexible adsorption layer 202 is provided with magnetism, enabling it to cooperate with the ferromagnetic metal powder 2012 in the base adhesive layer 201, thereby adsorbing the flexible adsorption layer 202 and the base adhesive layer 201 together.

[0055] In this embodiment, the flexible adsorption layer 202, as a rare-earth magnetic elastomer, possesses high strength and stability. Specifically, through the rational selection of raw materials and optimization of the preparation process, the flexible adsorption layer 202 can exhibit high mechanical strength and stability, withstand certain external forces and environmental changes, and maintain stable performance under different temperature, humidity, and other conditions.

[0056] In addition, the magnetic, elastic, and strength properties of the material can be controlled by adjusting the type, content, and particle size distribution of the magnetic material 2022, as well as the type and formulation of the elastomer matrix 2021, in order to meet the special requirements of different users.

[0057] The following method can be used to prepare the flexible adsorption layer 202: Mixing method: Magnetic material 2022 and elastomer matrix 2021 are mixed in a mixing device. The magnetic powder is uniformly dispersed in the matrix by mechanical force. Then, a flexible adsorption layer 202 with magnetic properties is obtained through extrusion molding and curing processes. This method is simple and low in cost.

[0058] In some exemplary embodiments, considering that the surface magnetic field strength of a curved surface changes with the curvature of the surface, and that the nature of this change is closely related to the vector characteristics of the magnetic field, the distribution of the field source, and the boundary conditions of the curved surface, the surface magnetic field strength of both sides of the flexible adsorption layer 202 can be optimized to improve the magnetic adsorption strength of the side of the flexible adsorption layer 202 facing the base adhesive layer 201 and to prevent the side of the flexible adsorption layer 202 away from the base adhesive layer 201 from adsorbing ferromagnetic items through the decorative layer 203. For example, the surface magnetic field strength of the first side of the flexible adsorption layer 202 facing the base adhesive layer 201 is ≥1000 Gs; the surface magnetic field strength of the second side of the flexible adsorption layer 202 away from the base adhesive layer 201 is ≤150 Gs.

[0059] The magnetic material 2022 is oriented and arranged. Specifically, during molding, an external magnetic field is used to guide the magnetic material 2022 to align in the same direction (such as perpendicular to the layer), so that the N / S poles of the magnetic powder are neatly facing one side (the first side of the flexible adsorption layer 202). After subsequent magnetization, the strong magnetic surface faces the base adhesive layer and the weak magnetic surface faces the decorative layer.

[0060] In some exemplary embodiments, the flexible adsorption layer 202 extends towards the base adhesive layer 201 from opposite sides in its width direction, forming a concave arc-shaped surface on the first surface and a convex arc-shaped surface on the second surface. This flexible adsorption layer 202 has a certain degree of plasticity, and the combination of flexible material and arc-shaped structure design allows it to better adhere to the nail 101.

[0061] It should be noted that, due to factors such as the differences in the nails 101 on different users and their different fingers 10, the curvature of the nail 101 can be freely adjusted for adsorption according to the curvature of the nail 101 on different users.

[0062] In some exemplary embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the decorative layer 203 includes a wearable armor, which is bonded to the flexible absorbent layer 202.

[0063] It should be noted that the wearable nail can be an appearance nail plate made of materials such as plastic (e.g., ABS resin) or gel, and its surface can be decorated with hand-painted patterns, stickers, rhinestones, sequins, etc.

[0064] In this embodiment, the accompanying drawings are also provided. Figures 1-4 A specific use case for nail art decoration 20 is explained.

[0065] First, a base coat 201 containing ferromagnetic metal powder 2012 (preferably x99 < 200 μm) is uniformly coated onto the armor.

[0066] Then, the flexible adsorption layer 202 is bonded to the decorative layer 203. A commonly used nail adhesive can be used to adhere it to the weakly magnetic surface of the flexible adsorption layer 202.

[0067] Finally, the flexible adsorption layer 202, made of rare-earth magnetic elastomer, is bonded to the base layer 201. Based on the flexibility and magnetic properties of the flexible adsorption layer 202, it ensures a good fit to the curvature of each person's nail 101, achieving a tighter adhesion.
