Description

Technical Field

[0001] This utility model relates to the field of home decoration board technology, specifically to a multi-layer composite fingerprint-resistant, easy-to-clean, skin-feel painted board. Background Technology

[0002] As modern home design demands increasingly sophisticated surface performance, consumers are placing greater emphasis on ease of cleaning, aesthetic appeal, and durability. They prefer furniture with smooth, fingerprint-resistant, and stain-resistant surfaces, such as soft-touch lacquered panels and fingerprint-resistant metal finishes. These products not only enhance the beauty of the home but also significantly reduce the difficulty of daily cleaning and maintenance, perfectly aligning with the consumer demand for both convenience and quality in today's fast-paced lifestyle.

[0003] However, the current mainstream easy-clean panel solutions still have significant technical bottlenecks: although coated products have basic hydrophobic and stain-resistant properties, they suffer from high costs, insufficient scratch resistance, weak corrosion resistance, and complex production processes; traditional melamine finishes, while cost-effective, have prominent fingerprint residue, limited stain resistance, and are prone to aging and yellowing with long-term use. Utility Model Content

[0004] In view of the above problems, this utility model provides a multi-layer composite anti-fingerprint easy-to-clean skin-feel painted panel to solve the problems of poor anti-fingerprint effect and difficulty in cleaning oil stains in traditional painted panels.

[0005] To achieve the above objectives, the applicant provides a multi-layer composite fingerprint-resistant, easy-to-clean, skin-feel painted panel, comprising: Substrate layer; A coating layer comprising: a primer layer and a functional layer; the primer layer is disposed on the top surface of the substrate layer and is used to flatten the substrate layer; The functional layer includes a fluorocarbon chain layer and a silica aerogel nanoparticle layer; the fluorocarbon chain layer and the silica aerogel nanoparticle layer are sequentially disposed on the side of the primer layer away from the substrate layer; the silica aerogel nanoparticle layer is used for hydrophobicity.

[0006] Furthermore, the fluorocarbon chain layer is a perfluoropolyether modified acrylate layer or a resin matrix layer of fluorosiloxane oligomers.

[0007] Furthermore, the coating layer is symmetrically disposed on opposite sides of the substrate layer.

[0008] Furthermore, the silica aerogel nanoparticle layer has multiple protrusions on the side away from the substrate layer, and the multiple protrusions are used for hydrophobicity.

[0009] Furthermore, the thickness of the substrate layer is between 15 mm and 18 mm.

[0010] Furthermore, the coating layer further includes a topcoat layer; the topcoat layer is located on the side of the primer layer away from the substrate layer, and the fluorocarbon chain layer is located on the topcoat layer.

[0011] Furthermore, the thickness of the topcoat layer is between 25 μm and 35 μm.

[0012] The advantages of the above technical solution compared to existing technologies are as follows: the fluorocarbon chain layer is set up so that, since the surface energy of the fluorocarbon chain layer is lower than that of grease and sweat, when grease drips onto the painted panel, the grease will shrink into spherical droplets instead of spreading out on the painted panel, thus making it easier to clean; the silica aerogel nanoparticle layer is sprayed on the fluorocarbon chain layer to reduce the actual contact area between the liquid and the surface of the painted panel and enhance the hydrophobic effect.

[0026] Please see Figure 1 and Figure 2 This embodiment provides a multi-layer composite fingerprint-resistant, easy-to-clean, skin-feel painted panel, comprising: Substrate layer 1; The coating layer includes a primer layer 2 and a functional layer 3; the primer layer 2 is placed on the top surface of the substrate layer 1 and is used to flatten the substrate layer 1; The functional layer 3 includes: a fluorocarbon chain layer 31 and a silica aerogel nanoparticle layer 32; the fluorocarbon chain layer 31 and the silica aerogel nanoparticle layer 32 are sequentially disposed on the side of the primer layer 2 away from the substrate layer 1; the silica aerogel nanoparticle layer 32 is used for hydrophobicity.

[0027] The substrate layer 1 is the main structure of the painted board, providing structural strength and serving as an adhesion carrier for the coating layer. The substrate layer 1 can be a series of regular structures such as blocks or discs; the substrate layer 1 can be made of MDF or solid wood core board, and its surface is flat to allow for better adhesion of the coating layer.

[0028] Primer layer 2 is formed by curing the primer applied to the surface of substrate layer 1. The primer is used to fill the pores on the surface of substrate layer 1. Specifically, the primer is applied to the surface of substrate layer 1 by electrostatic spraying. The components of the primer include epoxy-modified polyurethane resin, aliphatic isocyanate curing agent, adhesion promoter (silane coupling agent), and organosilicon or acrylate leveling agent. Applying the primer enhances the adhesion of the topcoat to the substrate.

[0029] The fluorocarbon chain layer 31 has low surface energy and is coated on the primer layer 2, which prevents oil and water from spreading on the painted panel surface, thus making it easy to clean.

[0030] Silica aerogel nanoparticles are disposed on the surface of fluorocarbon chain layer 31 to form a raised structure on the surface of the painted plate, thereby achieving superhydrophobicity and oleophobicity; the particle size of the silica aerogel nanoparticles is between 10 nm and 30 nm.

[0031] The thickness of functional layer 3 is between 0.5um and 5um. If it is too thick, it will affect the transparency and feel. If it is too thin, the hydrophobic and oleophobic effect of the painted board will not last.

[0032] Specifically, the substrate layer 1 is the main structure of the painted panel, with a flat top surface to facilitate the adhesion of the primer. The functional layer 3 greatly reduces the residue of oil and water stains.

[0033] A fluorocarbon chain layer 31 is provided. Since the surface energy of the fluorocarbon chain layer 31 is lower than that of grease and sweat, when grease drips onto the painted panel, the grease will shrink into spherical droplets instead of spreading out on the painted panel, thus making it easier to clean. A silica aerogel nanoparticle layer 32 is sprayed on the fluorocarbon chain layer 31 to reduce the actual contact area between the liquid and the surface of the painted panel and enhance the hydrophobic effect.

[0034] In this embodiment, the fluorocarbon chain layer 31 is a perfluoropolyether modified acrylate layer or a resin matrix layer of fluorosiloxane oligomers.

[0035] The perfluoropolyether modified acrylate layer can effectively resist the adhesion of contaminants such as grease and sweat, while the acrylate resin can ensure the adhesion between the coating and the underlying layer (topcoat layer 4 or primer layer 2). The silicon element in the resin matrix layer of fluorosiloxane oligomers can improve the aging resistance of the coating, making the fluorocarbon chain layer 31 less prone to yellowing and cracking after long-term use of painted panels; the fluorine element reduces the surface energy, ensuring uniform film formation of the coating and avoiding defects such as pinholes and bubbles.

[0036] Please see Figure 1 In this embodiment, the coating layer is symmetrically disposed on opposite two sides of the substrate layer 1.

[0037] The substrate layer 1 has a coating layer on both sides. During use, the top and bottom surfaces of the substrate layer 1 can be used as surfaces to reduce wear and tear on the painted panel during daily use and extend its service life.

[0038] Please see Figure 2 In this embodiment, the silica aerogel nanoparticle layer 32 has a plurality of protrusions 321 on the side away from the substrate layer 1, and the plurality of protrusions 321 are used for hydrophobicity.

[0039] Multiple protrusions 321 are provided to increase the surface roughness of the silica aerogel nanoparticle layer 32, which greatly reduces the contact area between water droplets and the coating surface. In addition, the silica aerogel nanoparticles have low surface energy. When water or liquid contaminants (such as oil) come into contact with the painted panel surface, they will not adhere to the surface under the action of the protrusions 321. They can be removed by slight tilting or wiping, which facilitates the cleaning of the painted panel.

[0040] In this embodiment, the thickness of the substrate layer 1 is between 15 mm and 18 mm.

[0041] When the thickness of the substrate layer 1 is less than 15mm, the paint panel has insufficient resistance to bending and compressive strength, and is prone to bending and deformation, which affects the user experience and also poses certain risks. When the thickness of the substrate layer 1 is greater than 18mm, the overall weight of the painted panel increases significantly, making it inconvenient to transport. It also increases production and installation costs and places higher demands on the load-bearing capacity of the accessories.

[0042] The thickness of the substrate layer 1 is preferably between 15 and 18 mm. This thickness is compatible with mainstream furniture accessories and facilitates subsequent processing (such as drilling and grooving).

[0043] A thickness of 15-18mm ensures that the substrate layer 1 does not deform during long-term use, reduces coating cracking and damage to the functional layer 3 caused by bending of the substrate layer 1, and ensures the overall stability of the painted panel.

[0044] Please see Figure 1 In this embodiment, the coating layer further includes a topcoat layer 4; the topcoat layer 4 is placed on the side of the primer layer 2 away from the substrate layer 1, and the fluorocarbon chain layer 31 is placed on the topcoat layer 4.

[0045] The topcoat layer 4 is disposed between the primer layer 2 and the fluorocarbon chain layer 31. It is formed by spraying the topcoat onto the primer layer 2 and then curing it. The topcoat is cured by UV light. The components of the topcoat include high cross-linking density polyurethane acrylate resin, nano-alumina with a particle size of 20-50nm and defoamer. Among them, nano-alumina can significantly improve the hardness and scratch resistance of the coating surface. At the same time, pigments can be added to the topcoat to give the surface of the painted panel color, thereby improving the aesthetics of the painted panel and meeting consumer demand.

[0046] In this embodiment, the thickness of the topcoat layer 4 is between 25 μm and 35 μm.

[0047] When the thickness of the topcoat layer 4 is less than 25μm, it is difficult to ensure the consistency of the thickness of the topcoat layer 4 in all places; when the thickness of the topcoat layer 4 is greater than 35μm, shrinkage cracking is likely to occur when the topcoat layer 4 is cured (the solvent inside the thick coating evaporates slowly, the surface cures first, and stress is generated when the inside shrinks), and the adhesion to the primer layer 2 decreases (the thick coating is easy to fall off).

[0048] A thickness of 25-35μm ensures uniform distribution of the topcoat while preventing cracking during curing and guaranteeing coating adhesion. It also ensures uniform color and consistent texture on the painted panel surface, enhancing its aesthetic appeal and preventing cracking during curing of the topcoat layer, thus extending the coating's lifespan.

[0049] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this utility model and utilizing the content described in the text and drawings of this utility model, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this utility model.
