Description

Technical Field

[0001] This utility model relates to the technical field of decorative panels, and in particular to a decorative panel with a digital printing media layer. Background Technology

[0002] Flooring, as a decorative and home furnishing material, is widely used in people's lives and work. Furthermore, as people's living standards improve, their functional requirements for flooring are also increasing, leading to different needs.

[0003] Digital printing technology has dramatically transformed the decorative panel industry, enabling high-resolution, customized designs for floors, walls, ceilings, and other building surfaces. Traditional decorative panels rely on lamination, direct printing, or coating techniques to achieve the desired aesthetics and durability. However, when the surface energy of the substrate is low, inks struggle to spread and adhere properly, leading to problems such as stains, peeling, or fading over time. Utility Model Content

[0004] In view of this, the present invention provides a decorative panel with a digital printing media layer to solve the above problems.

[0005] A decorative panel with a digital printing media layer includes a core layer, a media layer disposed on the core layer, an ink layer disposed on the media layer, and a wear-resistant layer disposed on the ink layer. The media layer is located on the upper surface of the core layer and has a porous structure. The upper surface of the media layer is a bonding surface. A surface-modified functional layer is formed on the upper surface of the media layer. The ink layer is permeated into the porous structure of the media layer before curing and is fixed to the media layer after curing.

[0006] Furthermore, the core layer is a substrate layer made of PVC, PET, PP, PTG or stone-plastic material.

[0007] Furthermore, the wear-resistant layer is formed using UV adhesive and is used to protect the surface of the ink layer from damage and oxidation.

[0008] Furthermore, the ink layer is composed of pigments, resins, solvents, and anchoring agents.

[0009] Furthermore, the medium layer is made of thermoplastic material or thermoplastic mineral composite board.

[0010] Furthermore, the functional layer is treated with a surface modifier.

[0011] Compared with existing technologies, the decorative panel with a digital printing media layer of this invention has a porous structure located on the upper surface of the core layer. This porous structure allows for partial ink penetration, improving adhesion strength. The ink layer is permeated into the porous structure of the media layer before curing, thus forming an interlocking physical structure after curing to prevent the ink layer from detaching from the media layer. A surface-modified functional layer is formed on the upper surface of the media layer. This functional layer is treated with a surface modifier, such as a coupling agent, to optimize surface free energy, thereby improving ink adhesion. Attached Figure Description

[0013] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0014] like Figure 1 The diagram shown is a structural schematic of a decorative panel with a digital printing media layer provided by this utility model. The decorative panel with the digital printing media layer includes a core layer 10, a media layer 20 disposed on the core layer 10, an ink layer 30 disposed on the media layer 20, and a wear-resistant layer 40 disposed on the ink layer 30. It is conceivable that the decorative panel with the digital printing media layer also includes other functional components, such as snap-fit ​​structures, waterproof layers, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0015] The core layer 10 is a substrate layer made of PVC, PET, PP, PTG or stone-plastic material, which is used to provide structural support.

[0016] The dielectric layer 20 is made of thermoplastic materials (such as PVC, PP, PET, modified PET / PP) or thermoplastic mineral composite boards (containing inorganic fillers such as calcium carbonate and silica). The dielectric layer 20 is located on the upper surface of the core layer 10 and has a porous structure, which allows some ink to permeate, improving adhesion strength. A surface-modified functional layer 21 is formed on the upper surface of the dielectric layer 20. This surface modification involves treatment with a surface modifier, such as a coupling agent, to optimize the surface free energy, thereby improving ink adhesion.

[0017] The ink layer 30 is composed of pigments, resin, solvent, and an anchoring agent. Before curing, the ink layer 30 is embedded within the porous structure of the medium layer 20, thereby forming an interlocking physical structure after curing to prevent the ink layer 30 from detaching from the medium layer 20. The anchoring agent enhances the chemical bond between the ink layer 30 and the medium layer 20, and the interlocking physical structure formed by the porous structure of the medium layer 20 and the ink layer 30 after curing synergistically improves adhesion.

[0018] The wear-resistant layer 40 protects the surface of the ink layer 30 from damage and oxidation. The wear-resistant layer 40 is formed using UV adhesive. UV adhesive works by a photoinitiator (or photosensitizer) in the material absorbing ultraviolet light and generating active free radicals or cations, initiating monomer polymerization and cross-linking chemical reactions. This causes the adhesive to transform from a liquid to a solid state within seconds. The curing principle is existing technology and will not be elaborated further. After curing, the UV adhesive is completely transparent, and the product does not yellow or whiten over a long period, allowing light to penetrate the surface of the ink layer 30 without affecting its color.

[0019] Compared with existing technologies, the decorative panel with a digital printing media layer of this invention has a porous structure on the upper surface of the core layer 10, where the media layer 20 is located. This porous structure allows for partial ink penetration, improving adhesion strength. The ink layer 30 is permeated into the porous structure of the media layer 20 before curing, thus forming an interlocking physical structure after curing to prevent the ink layer 30 from detaching from the media layer 20. A surface-modified functional layer 21 is formed on the upper surface of the media layer 20. The functional layer 21 is treated with a surface modifier, such as a coupling agent, to optimize its surface free energy, thereby improving ink adhesion.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
