[0028] 3 tear-resistant layer 4 finishing layer

[0029] 5 Protective layer 6 Adhesive layer DETAILED DESCRIPTION

[0030] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] like Figures 1 to 2 The tear-resistant decorative PVC sheet includes a PVC base layer 1, which is different in that an adhesive layer 2 is provided on the PVC base layer 1, and a tear-resistant layer 3 is infiltrated in the adhesive layer 2 to form a tear-resistant adhesive layer. In this way, the overall tear resistance of the sheet can be improved, and it will not be torn due to the force of pulling when pasting and arranging, and it can be better adhered to the non-planar attachment surface. At the same time, in order to achieve an effective decorative effect, a finishing layer 4 is provided on the tear-resistant adhesive layer. In addition, in order to reduce the premature yellowing of the finishing layer 4 due to the influence of ultraviolet rays, a protective layer 5 is fused on the finishing layer 4. And it can rely on the protective layer 5 to provide appropriate wear-resistant protection to prevent the finishing layer 4 from being directly exposed and contacting the outside. Furthermore, an adhesive layer 6 is provided at the bottom of the PVC base layer 1. In this way, it can be stably adhered to the surface of the object to be decorated as needed.

[0032] In view of a preferred embodiment of the utility model, the thickness of the PVC base layer 1 is 0.3 to 1 mm. In this way, the self-stability can be taken into account when not subjected to large tensile stress. At the same time, a number of stress release holes are distributed on the PVC base layer 1. In this way, it can avoid excessive stress on local points when subjected to stress, causing tearing, and achieve appropriate stress transfer and release. During the implementation, the thickness of the PVC base layer 1 is 0.5 mm, and the stress release holes are distributed in a dot matrix pattern, which meets the use needs of conventional finishing products.

[0033] Further, in order to achieve a stable bond, the adhesive layer 2 used is a UV-curable glue layer, and the thickness of the adhesive layer 2 is 0.2 to 0.5 mm. In this way, the tear-resistant layer 3 can be wetted and bonded, and the finishing layer 4 can also be effectively bonded. Moreover, after the adjustment is completed, rapid curing can be achieved by ultraviolet light irradiation.

[0034] In combination with the actual implementation, the tear-resistant layer 3 used in the utility model is a polyurethane film layer, and the polyurethane film layer has a mesh structure, and the thickness of the polyurethane film layer is 0.1 to 0.4 mm. Specifically, the mesh structure used is a honeycomb mesh structure, and the diagonal spacing of the honeycomb mesh is 3 to 5 mm. In this way, when encountering a non-horizontal surface for bonding, the honeycomb mesh structure can better transfer stress and avoid local tearing. At the same time, if cutting is required, the actual tear resistance of the honeycomb mesh structure will not be destroyed, and it can be better bonded to the irregular surface of the object.

[0035] Further, the facing layer 4 is a facing paper layer, and the thickness of the facing paper layer is 0.1 to 0.2 mm. In this way, the conventional flat surface combination decoration needs can be met. At the same time, for the decoration needs of some curved surfaces, the facing layer 4 can also be a pigment spraying layer, and the thickness of the pigment spraying layer is 0.03 to 0.15 mm. In this way, wrinkles caused by the facing paper layer will not appear, and the decorative effect is better.

[0036] At the same time, in order to minimize the impact of ultraviolet rays from sunlight during daily use and slow down the yellowing of the finishing layer 4, the protective layer 5 is a UV absorber UV-9 fusion layer. During the manufacturing process, the UV absorber UV-9 in a hot melt state is poured onto the finishing paper layer according to the set thickness, and solidification and bonding can be achieved after cooling.

[0037] Furthermore, considering the need for a firm bond during the use of the adhesive, the adhesive layer 6 is a hot melt adhesive layer with a thickness of 0.2 to 1 mm. Furthermore, considering the need for enhancing certain decorative effects, a fluorescent layer may also be sprayed on the finishing layer 4.

[0038] The manufacturing process of the utility model is roughly as follows:

[0039] Cut the PVC base layer 1 of suitable size. Shape the polyurethane through a mold to form a polyurethane film layer with a mesh structure.

[0040] Afterwards, an adhesive layer 2 is laid on the PVC base layer 1, and a tear-resistant layer 3 is placed thereon to form a tear-resistant adhesive layer.

[0041] Next, select the facing paper layer with the corresponding color and texture according to the needs. Then, perform appropriate lamination and positioning. When it is at the appropriate thickness, turn on the ultraviolet light irradiation for curing.

[0042] Then, pour the hot melt UV absorber UV-9 solvent. Similarly, the thickness of the forming is controlled by the pressing equipment. After natural cooling, the finished product can be trimmed.

[0043] Finally, according to the use requirements, the adhesive layer 6 is distributed behind the PVC base layer 1.

[0044] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:

[0045] 1. The PVC base layer has stress relief holes, which can provide appropriate resistance to tearing, ensuring stable load-bearing while reducing accidental tearing.

[0046] 2. An independent tear-resistant layer is provided to evenly disperse the tearing stress and avoid concentrated force.

[0047] 3. The finishing layer can be selected according to usage requirements to provide different decorative effects.

[0048] 4. Equipped with a protective layer, it can reduce the yellowing and aging effects of ultraviolet rays on the finishing layer.

[0049] 5. The overall structure is simple, easy to manufacture, and convenient to use, similar to a single-layer sticker.

They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
