Description

Technical Field

[0001] This utility model relates to the field of decorative wall sticker technology, specifically to a novel structural decorative wall sticker. Background Technology

[0002] Decorative wall stickers are functional wall coverings that quickly beautify walls using prefabricated materials. They typically consist of a base layer, a decorative layer, and an adhesive layer, and are made of PVC, non-woven fabric, or composite materials. They are fixed to the wall surface using adhesives (such as pressure-sensitive adhesives or solvent-based adhesives) or physical adsorption methods. They are widely used in modular decoration scenarios in residential and commercial spaces and have advantages such as convenient construction and customizable patterns.

[0003] However, in commercial spaces where decorative wall stickers need to be changed frequently, existing decorative wall stickers are difficult to meet the needs. Because existing technology relies too much on adhesives to achieve permanent or semi-permanent fixation when installing decorative wall stickers, it is very inconvenient to install and remove them. In particular, the wall sticker itself and the wall surface are easily damaged when disassembling.

[0004] In view of this, a new type of structural decorative wall sticker is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional decorative wall stickers, which require adhesive installation, are prone to damage to themselves and the wall surface when removed, and to provide a new type of decorative wall sticker.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel structural decorative wall sticker, comprising a metal plate pre-installed on a wall, a substrate, and multiple arrays of neodymium iron boron magnetic strips fixedly connected to the substrate. The substrate comprises a substrate layer, a reinforcing layer, a buffer layer, a waterproof layer, and a protective layer stacked sequentially. The multiple layers are assembled by a hot-pressing composite process. A decorative panel is slidably disposed on the substrate. A T-shaped mounting strip is fixedly connected to one side of the substrate. An mounting groove for mounting a mounting strip of another substrate is provided on the other side of the substrate. Two limiting rods are fixedly connected to the top of the substrate. Two limiting grooves for limiting the two limiting rods of another substrate are provided at the bottom of the substrate.

[0007] Preferably, a clamping strip with a T-shaped cross-section is fixedly connected to the decorative panel, and a clamping groove for clamping the clamping strip is provided on the substrate. The clamping groove extends through the top of the substrate, and the length of the clamping strip and the clamping groove is less than the length of the substrate.

[0008] Preferably, the substrate layer is made of modified polypropylene honeycomb board, the thickness of the substrate layer is 2-3mm, the substrate layer is used for direct installation with neodymium iron boron magnetic strips, and provides a flat surface for the reinforcement layer to adhere.

[0009] Preferably, the reinforcing layer is made of glass fiber and has a thickness of 1-2 mm. The reinforcing layer is used to enhance the mechanical strength and impact resistance of the substrate to provide structural support for the substrate as a whole.

[0010] Preferably, the buffer layer is made of ethylene-vinyl acetate copolymer, the thickness of the buffer layer is 1-1.5 mm, and the buffer layer is used to absorb shock and enhance the adhesion between layers.

[0011] Preferably, the waterproof layer is made of polyester film, and the thickness of the waterproof layer is 0.1-0.2 mm. The waterproof layer is used to prevent water penetration, so as to protect the internal structure of the substrate from moisture and extend the service life of the substrate.

[0012] Preferably, the protective layer is made of a microporous breathable PET film, and the thickness of the protective layer is 0.05-0.1 mm. The protective layer is used to protect the substrate surface during transportation and installation.

[0013] Compared with the prior art, this utility model has the following beneficial effects:

[0014] The novel decorative wall sticker provided by this utility model uses a mechanical interlocking structure of T-shaped installation strip and limiting rod, and utilizes the adsorption connection between neodymium iron boron magnetic strip and pre-installed metal plate. This enables non-destructive disassembly of the decorative panel and the substrate and high-precision alignment of multi-unit splicing without the need for adhesives, reducing the risk of wall damage and improving construction efficiency.

[0015] The novel decorative wall sticker provided by this utility model adopts a five-layer hot-pressed composite structure consisting of a modified polypropylene honeycomb board substrate layer, a glass fiber reinforcement layer, an EVA buffer layer, a polyester film waterproof layer, and a microporous breathable PET protective layer. This structure can significantly improve the bending stiffness of the substrate and enhance its shock absorption and energy absorption performance, while forming a moisture barrier, thereby extending the service life of the decorative wall sticker in humid or high-impact environments.

[0016] The novel decorative wall sticker provided by this utility model designs the substrate as a separable layered structure and adopts a sliding connection method of clamping strips and clamping grooves, which can support the independent replacement of a single substrate and replace the decorative panel without disassembling the substrate, reducing maintenance costs and meeting the dynamic needs of high-frequency replacement scenarios such as commercial spaces.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1-6 .

[0027] This utility model discloses a novel decorative wall sticker, comprising a metal plate 1 pre-installed on a wall, a base plate 2, and multiple arrayed neodymium iron boron magnetic strips 3 fixedly connected to the base plate 2. The base plate 2 includes a substrate layer 21, a reinforcing layer 22, a buffer layer 23, a waterproof layer 24, and a protective layer 25 stacked sequentially. The multiple layers are assembled by a hot-pressing composite process. A decorative panel 4 is slidably disposed on the base plate 2. A mounting strip 5 with a T-shaped cross-section is fixedly connected to one side of the base plate 2, and a mounting groove 6 for mounting another mounting strip 5 of the base plate 2 is provided on the other side of the base plate 2. The top of the base plate 2 is fixedly connected to... There are two limiting rods 9, and the bottom of the substrate 2 is provided with two limiting grooves 10 for limiting the two limiting rods 9 of the other substrate 2. The limiting grooves 10 are used to cooperate with the limiting rods 9 to achieve the longitudinal positioning of the substrate 2. That is to say, through the pre-installed metal plate 1 and substrate 2, and the neodymium iron boron magnetic strip 3 fixed thereon, the decorative wall sticker can be quickly and firmly installed on the wall. At the same time, the multi-layer structure design provides good mechanical and protective performance. In addition, the substrate 2 can be connected to another substrate 2 in multiple directions, further improving the convenience of installation and the overall stability.

[0028] The decorative panel 4 is fixedly connected with a T-shaped clamping strip 7. The base plate 2 is provided with a clamping groove 8 for clamping the clamping strip 7. The clamping groove 8 passes through the top of the base plate 2. The length of the clamping strip 7 and the clamping groove 8 is less than the length of the base plate 2. The design of the clamping strip 7 and the clamping groove 8 allows the decorative panel 4 to be firmly fixed on the base plate 2, while allowing the decorative panel 4 to slide, which is convenient for installation and replacement. This design further increases the overall stability of the decorative wall sticker.

[0029] Secondly, the substrate layer 21 is made of modified polypropylene honeycomb board with a thickness of 2-3mm. The substrate layer 21 is used for direct installation with neodymium iron boron magnetic strips 3 and provides a flat surface for the reinforcement layer 22 to adhere. Since the modified polypropylene honeycomb board is lightweight and strong, it can provide an installation surface and has good heat insulation and sound insulation properties, providing a solid foundation for the entire decorative wall sticker.

[0030] Furthermore, the reinforcing layer 22 is made of glass fiber and has a thickness of 1-2 mm. The reinforcing layer 22 is used to enhance the mechanical strength and impact resistance of the substrate 2 to provide structural support for the substrate 2 as a whole. This is because the glass fiber reinforcing layer 22 can significantly improve the strength and rigidity of the substrate 2, enabling it to better resist external forces and impacts, and ensuring the long-term durability of the decorative wall sticker.

[0031] In addition, the buffer layer 23 is made of ethylene-vinyl acetate copolymer and has a thickness of 1-1.5 mm. The buffer layer 23 is used to absorb shock and energy and enhance the adhesion between layers. In other words, the buffer layer 23 can absorb external impacts, reduce vibration transmission, and enhance the adhesion between layers, making the whole structure more robust and durable.

[0032] Furthermore, the waterproof layer 24 is made of polyester film with a thickness of 0.1-0.2mm. The waterproof layer 24 is used to prevent water penetration, protect the internal structure of the substrate from moisture, and extend the service life of the substrate. The waterproof layer 24 enables the substrate to effectively isolate moisture, protect the internal structure from moisture damage, thereby extending the service life of the decorative wall sticker and maintaining its aesthetics.

[0033] Furthermore, the protective layer 25 is made of a microporous breathable PET film with a thickness of 0.05-0.1mm. The protective layer 25 is used to protect the substrate surface during transportation and installation. It should be noted that while protecting the substrate surface, the microporous breathable PET film protective layer 25 also allows gas exchange, which helps to prevent the accumulation of internal moisture and ensures the long-term stability of the decorative wall sticker.

[0034] It should be noted that this new type of layered decorative wall sticker, by combining different materials, provides a solution that is easy to install, high-strength, provides good protection, and is durable. It not only meets the needs of aesthetic and personalized decoration, but also takes into account practicality and the convenience of long-term maintenance.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
