Description

Technical Field

[0001] This utility model relates to the field of wallpaper technology, and more particularly to a recyclable tear-and-stick wallpaper and wall decoration structure. Background Technology

[0002] Wallpaper is an interior decoration material, popular for its diverse materials and patterns. Among wallpapers, there is a type called self-adhesive wallpaper. Its structure consists of a thin PVC embossed layer, an adhesive layer, and a release paper layer. This type of wallpaper has relatively limited patterns and designs. After removing the release paper layer, it can be pasted. However, this type of wallpaper requires some installation experience. Because it is designed to be firmly attached, repeated tearing and re-pasting due to installation errors can easily lead to dimensional changes or damage during the peeling process. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a recyclable tear-and-stick wallpaper and wall decoration structure. Because the substrate layer is one of non-woven paper, non-woven fabric, cross-woven base layer, or polyester fabric, it is not easily deformed when stretched. The surface layer, composed of a textured layer and a printed pattern layer, allows for richer wallpaper colors and textures to meet the needs of more consumers. Furthermore, the textured layer prevents creases and cracks from forming when the printed pattern layer is bent. The hot-melt pressure-sensitive adhesive layer possesses both hot-melt and pressure-sensitive properties; it is applied in a molten state and, after cooling and hardening, is applied with a light pressure-sensitive adhesive. The pressure-sensitive adhesive allows for quick bonding and easy peeling without contaminating the bonded surface. One side of the hot-melt pressure-sensitive adhesive layer is curved, reducing dimensional changes in the substrate and surface layers during repeated peeling and pasting. Therefore, this application allows for easy removal and re-pasting when needed. The substrate layer takes into account the dimensional changes during repeated peeling and pasting, ensuring the wallpaper is not easily deformed even with multiple peeling and pasting cycles. Compared to traditional wallpaper / wall coverings, this application reduces the use of primer and pre-mixed adhesives during installation, making installation more convenient.

[0004] To achieve the above objectives, the present invention provides a recyclable peelable wallpaper, comprising a substrate layer, a hot melt pressure-sensitive adhesive layer and a surface layer disposed on the surface of the substrate layer, and a release film layer disposed on the surface of the hot melt pressure-sensitive adhesive layer. The release film layer, the hot melt pressure-sensitive adhesive layer, the substrate layer and the surface layer are arranged sequentially from the inside to the outside. The hot melt pressure-sensitive adhesive layer and the surface layer are respectively located on both sides of the substrate layer. The surface layer is one or more of a textured layer and a printed pattern layer.

[0005] As a preferred embodiment, the surface layer further includes a functional effect layer, which is disposed on the surface of the printed pattern layer, and the basis weight of the functional effect layer is 20-80 g / m².

[0006] As a preferred embodiment, the substrate layer is one of non-woven paper layer, non-woven fabric layer, cross-woven base layer or polyester fabric, and the basis weight of the substrate layer is 80-150g / ㎡.

[0007] As a preferred embodiment, the hot melt pressure-sensitive adhesive layer is a layer structure formed by coating hot melt pressure-sensitive adhesive onto the surface of a substrate layer, and the basis weight of the hot melt pressure-sensitive adhesive layer is 50-150 g / m².

[0008] As a preferred embodiment, the side of the hot melt pressure-sensitive adhesive layer that contacts the release film layer is arc-shaped.

[0009] As a preferred embodiment, the textured layer is one of an embossed layer, a foamed embossed layer, or a textile textured layer, and the basis weight of the textured layer is 150-300 g / m².

[0010] As a preferred embodiment, the printed pattern layer is one or more layers, the printed pattern layer is a planar pattern layer or a three-dimensional pattern layer, and the basis weight of the printed pattern layer is 20-80 g / m².

[0011] As a preferred embodiment, the quantitative amount of the release film layer is 20-50 g / m².

[0012] This application also provides a wall decoration structure, including a recyclable tear-and-stick wallpaper as described in any of the above claims. The wall decoration structure includes a smooth wall surface and a recyclable tear-and-stick wallpaper attached to the smooth wall surface. The basis weight of the recyclable tear-and-stick wallpaper is 300-800g / ㎡. The smooth wall surface is one of glass wall surface, tile wall surface, metal wall surface, marble wall surface or paint wall surface with a topcoat layer.

[0013] The beneficial effects of this utility model are as follows: Since the substrate layer is one of non-woven paper, non-woven fabric, cross-woven base layer, or polyester fabric, the substrate layer is not easily deformed when stretched; the surface layer composed of texture layer and printed pattern layer makes the wallpaper colors and textures richer to meet the needs of more consumers, and the texture layer makes the printed pattern layer less prone to creases and cracks when bent; the hot melt pressure-sensitive adhesive layer has dual characteristics of hot melt and pressure sensitivity. It can be applied in a molten state, and after cooling and hardening, it can quickly achieve bonding by applying light pressure. At the same time, it can be peeled off relatively easily and is not easy to contaminate the bonded surface. Moreover, one side of the hot melt pressure-sensitive adhesive layer is arc-shaped, which can reduce the dimensional changes of the substrate layer and surface layer during repeated tearing and pasting; therefore, this application can be peeled off and re-pasted when needed. The substrate layer takes into account the dimensional change rate of repeated tearing and pasting, so the wallpaper is not easily deformed even if multiple repeated tearing and pasting actions occur.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] This utility model provides a recyclable peelable wallpaper, comprising a substrate layer 10, a hot-melt pressure-sensitive adhesive layer 20 and a surface layer 30 disposed on the surface of the substrate layer 10, and a release film layer 40 disposed on the surface of the hot-melt pressure-sensitive adhesive layer 20. The release film layer 40, the hot-melt pressure-sensitive adhesive layer 20, the substrate layer 10 and the surface layer 30 are arranged sequentially from the inside to the outside, with the hot-melt pressure-sensitive adhesive layer 20 and the surface layer 30 located on opposite sides of the substrate layer 10. The surface layer 30 is one or more of a textured layer 31 and a printed pattern layer 32. Since the substrate layer 10 is one of a non-woven paper layer, a non-woven fabric layer, a cross-woven base layer or a polyester fabric, the substrate layer 10 is not easily deformed when stretched. The surface layer 30, composed of the textured layer 31 and the printed pattern layer 32... This allows for a richer variety of wallpaper colors and textures to meet the needs of more consumers. Furthermore, the texture layer 31 prevents creases and cracks from forming when the printed pattern layer 32 is bent. The hot-melt pressure-sensitive adhesive layer 20 possesses both hot-melt and pressure-sensitive properties. When applied in a molten state and cooled and hardened, it quickly bonds with light pressure. It is also relatively easy to peel off and does not easily contaminate the bonded surface. One side of the hot-melt pressure-sensitive adhesive layer 20 is curved, which reduces dimensional changes to the substrate layer 10 and the surface layer 30 during repeated peeling and pasting. Therefore, this application allows for easy removal and re-pasting when needed. The substrate layer 10 takes into account the dimensional change rate of repeated peeling and pasting, ensuring that the wallpaper is not easily deformed even after multiple peeling and pasting cycles.

[0024] It also includes a functional effect layer 50, which is disposed on the surface of the printed pattern layer 32. The basis weight of the functional effect layer is 20-80 g / ㎡. The functional effect layer 50 is one or more layers, and the functional effect layer 50 is one or more of the following: waterproof and stain-resistant layer, antibacterial layer, mildew-proof layer or mite-proof layer.

[0025] The substrate layer 10 is one of non-woven paper layer, non-woven fabric layer, cross-woven base layer or polyester fabric. The basis weight of the substrate layer 10 is 80-150g / ㎡. The substrate layer 10 made of non-woven paper layer, non-woven fabric layer, cross-woven base layer or polyester fabric is not easily deformed when stretched.

[0026] The hot-melt pressure-sensitive adhesive layer 20 is a layer structure formed by coating the hot-melt pressure-sensitive adhesive onto the surface of the substrate layer 10. The basis weight of the hot-melt pressure-sensitive adhesive layer 20 is 50-150 g / m². The hot-melt pressure-sensitive adhesive used in this application is mainly a thermoplastic polymer, specifically including polyurethane adhesives, SIS (polystyrene-isoprene-styrene copolymer), SBS (polystyrene-butadiene-styrene copolymer), SEBS (polystyrene-ethylene-butadiene-styrene copolymer), etc. The side of the hot-melt pressure-sensitive adhesive layer 20 that contacts the release film layer 40 is arc-shaped. The arc shape can reduce the dimensional changes of the substrate layer 10 and the surface layer 30 caused by repeated peeling and sticking. Specifically, one side of the hot-melt pressure-sensitive adhesive layer 20 is thicker in the middle and thinner at the edges, with the middle thickness being 5-10% greater than the edges.

[0027] The texture layer 31 is one of the following: embossed layer, foamed embossed layer, or textile texture layer. The basis weight of the texture layer 31 is 150-300 g / ㎡. Specifically, the embossed layer generally refers to a textured layer structure formed by pressing a thermoplastic resin (such as PVC, polyurethane, etc.) slurry / film under high pressure while hot. The foamed embossed layer is mainly a thermoplastic resin slurry with added foaming agent, which is pressed under high temperature and high pressure to form a relatively loose textured layer structure. The textile texture layer is a layer structure formed by textile jacquard fabric. Therefore, the texture layer has a certain degree of flexibility, and the composite increases the compactness of the substrate layer 10 structure. It is not easy to produce creases when bending during the installation process, and it is not easy to deform when peeled off after installation, making it easy for consumers without installation experience to install.

[0028] The printed pattern layer 32 can be one or more layers, and can be a planar pattern layer or a three-dimensional pattern layer. The basis weight of the printed pattern layer 32 is 20-80 g / m². The printed pattern layer 32 can be set to one or more layers as needed. The specific printed pattern layer can be formed by methods such as rotary screen printing, letterpress printing, gravure printing, and digital printing. The planar or three-dimensional effect of the printed pattern layer 32 mainly depends on the solid content of the ink required for printing. A higher solid content will result in a more obvious three-dimensional effect of the pattern layer, while a lower solid content will result in a more prominent planar effect.

[0029] The quantitative concentration of release film layer 40 is 20-50 g / m².

[0030] like Figure 1 The illustration shows an embodiment of this application, in which the reusable tear-and-stick wallpaper 70 has a basis weight of 300 g / m², comprising a substrate layer 10, which is a non-woven paper layer with a basis weight of 80 g / m²; a hot-melt pressure-sensitive adhesive layer 20, which is a flat-coated adhesive layer with a basis weight of 50 g / m²; a surface layer 30, which is a textured layer 31, specifically a foamed embossed layer with a basis weight of 150 g / m²; and a release film layer 40 with a basis weight of 20 g / m². The reusable tear-and-stick wallpaper 70, after 10 cycles of tearing and sticking, exhibits a dimensional change rate of 0.1%.

[0031] like Figure 2 The illustration shows Embodiment 2 of this application, in which the reusable tear-and-stick wallpaper 70 has a basis weight of 500 g / m², including a substrate layer 10 made of non-woven fabric with a basis weight of 120 g / m²; a hot-melt pressure-sensitive adhesive layer 20, which is a flat-coated adhesive layer with a basis weight of 120 g / m²; a surface layer 30 consisting of a textured layer 31 and a printed pattern layer 32 disposed on the textured layer 31, with a basis weight of 220 g / m². The textured layer 31 is an embossed layer, and the printed pattern layer 32 is formed by rotary screen printing with a basis weight of 20 g / m². The release film layer 40 has a basis weight of 20 g / m². After 10 cycles of tearing and sticking, the reusable tear-and-stick wallpaper 70 exhibits a dimensional change rate of 0.4%.

[0032] like Figure 3 As shown, this is Embodiment 3 of this application. The difference between this embodiment and Embodiment 2 is that one side of the hot-melt pressure-sensitive adhesive layer 20 is thicker in the middle and thinner around the edges, with the middle thickness being 5% greater than the edges. This reusable tear-and-stick wallpaper 70, after 10 cycles of tearing and sticking, showed a dimensional change rate of 0.3%.

[0033] like Figure 4 The illustration shows Embodiment 4 of this application. The reusable tear-and-stick wallpaper 70 has a basis weight of 800 g / m², including a non-woven fabric substrate layer 10 with a basis weight of 150 g / m²; a hot-melt pressure-sensitive adhesive layer 20 with one side thicker in the middle and thinner around the edges, the middle being 10% thicker than the edges, with a basis weight of 150 g / m²; a surface layer 30 consisting of a textured layer 31 and a printed pattern layer 32 on the textured layer 31, with a basis weight of 300 g / m² and being an embossed layer; and a printed pattern layer 32 formed by letterpress printing with a basis weight of 80 g / m²; a functional layer 50 a composite layer consisting of a waterproof and stain-resistant layer and a mildew-resistant layer, with a basis weight of 80 g / m²; and a release film layer 40 with a basis weight of 40 g / m². After 10 cycles of tearing and sticking, the reusable tear-and-stick wallpaper 70 exhibits a dimensional change rate of 0.1%.

[0034] like Figure 5 As shown, this application also provides a wall decoration structure, including a recyclable tear-and-stick wallpaper. The wall decoration structure includes a smooth wall surface 60 and a recyclable tear-and-stick wallpaper 70 attached to the smooth wall surface 60. The basis weight of the recyclable tear-and-stick wallpaper is 300-800 g / m². The smooth wall surface 60 is one of glass wall surface, tile wall surface, metal wall surface, marble wall surface, or painted wall surface with a topcoat layer. The smooth wall surface 60 has a flat surface and relatively few pores, providing sufficient material for the recyclable tear-and-stick wallpaper. The wallpaper 70 adheres evenly. Furthermore, when the wallpaper is removed, the wall surface is less likely to be damaged. During the actual installation process, first remove the release film layer 40 of the reusable peelable wallpaper 70, align it, and adhere it to the smooth wall surface 60. After achieving a satisfactory installation effect, press to increase the bonding strength between the smooth wall surface 60 and the wallpaper. Thus, the reusable peelable wallpaper 70 is suitable for consumers without installation experience, facilitating error correction during installation and reducing the wallpaper installation scrap rate.
