Abstract
Description
Technical Field
[0001] This utility model relates to the field of wallpaper technology, and in particular to a novel high-strength composite PVC self-adhesive wallpaper. Background Technology
[0002] Composite PVC self-adhesive wallpaper is a decorative wall covering material made primarily of PVC (polyvinyl chloride) through a multi-layer composite process. Its structure typically includes a PVC base layer (providing strength and pattern), a reinforcing layer (such as non-woven fabric / fiberglass cloth, enhancing toughness), and a self-adhesive layer (adhesive backing, for direct application to the wall). It is wear-resistant, easy to clean, and supports DIY installation. It is directly adhered to a smooth wall surface via the adhesive backing and is widely used in homes and commercial spaces, combining decorative and practical functions.
[0003] Currently, composite PVC self-adhesive wallpaper is difficult to separate from the wall when it is damaged and needs to be replaced, as it is directly bonded to the wall. Furthermore, residual adhesive is difficult to clean, and the product's convenience needs improvement. Utility Model Content
[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a new type of high-strength composite PVC self-adhesive wallpaper.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A novel high-strength composite PVC self-adhesive wallpaper includes a base layer, an adhesive layer fixedly connected to the upper end of the base layer, a surface layer provided at the lower end of the base layer, a protective layer fixedly connected to the lower end of the surface layer, a support layer fixedly connected to the upper end of the surface layer, and multiple vertically arranged connecting rods fixedly connected to the upper end of the support layer. Semi-circular limiting blocks are fixedly connected to both sides of each connecting rod, and the upper end of each connecting rod is tapered. The lower end of the base layer has slots corresponding to the connecting rods, and the inner wall of each slot has grooves corresponding to the limiting blocks.
[0007] Preferably, the adhesive layer is made of acrylic pressure-sensitive adhesive, and release paper is adhered to its back side.
[0008] Preferably, the connecting rod and the limiting block are both made of PET injection-molded rigid plastic.
[0009] Preferably, the protective layer is made of acrylic polyurethane varnish.
[0010] Preferably, both the support layer and the base layer are made of PET film.
[0011] Preferably, the thickness of the base layer is 0.3-0.5 mm.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model, through the combined design of adhesive layer, slot, card slot, connecting rod and limiting block, allows the surface layer of wallpaper to be easily removed and replaced after it is adhered to the wall, significantly improving the ease of operation and practicality.
[0014] 2. This utility model, through the synergistic support structure of the support layer and the base layer, enhances the surface layer's resistance to deformation while effectively ensuring the stability of the surface structure, further strengthening the overall practical performance;
[0015] 3. This utility model, through the synergistic effect of its multi-layer structure, enables convenient disassembly and replacement of the surface layer after the wallpaper is adhered to the wall, while enhancing its resistance to deformation, and has good market application prospects.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-3A novel high-strength composite PVC self-adhesive wallpaper includes a base layer 6, a support layer 3, and a base layer 6. Both the base layer 6 and the support layer 3 are made of PET film, which provides good support strength. The thickness of the base layer 6 is 0.3-0.5mm to facilitate the installation of slots. An adhesive layer 7 is fixedly connected to the upper end of the base layer 6 to bond the base layer 6 to the wall. The adhesive layer 7 is made of acrylic pressure-sensitive adhesive, and release paper is adhered to its back to protect the adhesive layer 7. A surface layer 1 is provided at the lower end of the base layer 6. The surface layer 1 is made of PVC. A protective layer 2 is fixedly connected to the lower end of the surface layer 1 to protect the surface layer 1. The protective layer 2 is made of acrylic polyurethane varnish to form a wear-resistant and stain-resistant protective film. A support layer 3 is fixedly connected to the upper end of the surface layer 1 to support the surface layer 1.
[0022] In this embodiment, a plurality of vertically arranged connecting rods 4 are fixedly connected to the upper end of the support layer 3, which are used to cooperate with the slot to realize the disassembly and assembly of the surface layer 1. The connecting rods 4 and the limiting blocks 8 are both made of PET injection molded hard plastic, which is used to improve the strength of the connecting rods 4 and the limiting blocks 8. Semi-circular limiting blocks 8 are fixedly connected to both sides of the connecting rods 4, which are used to lock the connecting rods 4 in conjunction with the limiting grooves. The upper end of the connecting rods 4 is tapered, which is used to facilitate the insertion of the connecting rods 4 into the slots. The lower end of the base layer 6 is provided with a slot corresponding to the connecting rods 4. The inner side wall of the slot is provided with a slot 9 corresponding to the limiting blocks 8, which is used to accommodate the limiting blocks 8.
[0023] In this embodiment, the base layer 6 is first fixed to the wall by adhesive layer 7 (the release paper is removed in advance), and then the surface layer 1 is attached to the support layer 3. During the attachment process, the connecting rod 4 is inserted into the slot of the base layer 6. When inserted, the limiting block 8 is squeezed and deformed. After it is fully inserted, the limiting block 8 resets and is locked into the slot 9 to achieve positioning, preventing the connecting rod 4 from loosening and completing the installation of the surface layer 1. When disassembling, the connecting rod 4 can be pulled out of the slot to complete the quick disassembly of the surface layer 1.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
