Description

Technical Field

[0001] This utility model belongs to the field of wallpaper technology, and in particular relates to a thin, three-dimensional wall covering and its decorative structure. Background Technology

[0002] Wallpaper and wall coverings, also known as wall coverings, are interior decoration materials that are pasted on walls. Due to their diverse colors, rich patterns, safety, environmental friendliness, and convenient construction, they are widely used.

[0003] There are various types of wallpaper / wallcoverings, among which PVC wallpaper / wallcoverings are the most classic. Specifically, there are thin PVC wallpapers on the market, with a thickness of less than 0.3mm. The structure mainly consists of a thin PVC textured layer (unfoamed) and an adhesive backing layer. This type of wallpaper has a weak texture and is very inexpensive; however, it requires great care during installation. When smoothing the wallpaper to remove air bubbles during installation, it is very easy to scratch and / or wrinkle, which will affect the decoration. If installation problems occur, the problematic wallpaper usually needs to be removed and recut and pasted, which can easily lead to waste and damage to the wall surface.

[0004] Another common type of PVC wall covering on the market is made by thickly brushing a layer of PVC foam paste onto the base paper. After embossing, it forms a PVC wall covering with a rich three-dimensional effect. Its overall thickness is relatively thick (generally more than 0.5mm), with a rich three-dimensional effect. The price is higher than that of thin PVC wallpaper. It is installed using wallpaper glue. If there are any problems during the installation, the wall covering can be peeled off and aligned before installation, which does not easily cause waste during the installation process.

[0005] Based on the existing PVC wallpapers / wallcoverings on the market, it is difficult to find a new type of PVC wallpaper / wallcovering that can combine the above advantages and meet consumer needs; therefore, improvements are needed. Utility Model Content

[0006] The purpose of this utility model is to provide a lightweight three-dimensional wall covering and its decorative structure, aiming to solve the technical problems of existing lightweight PVC wallpaper, such as the difficulty in construction, easy tearing and / or wrinkling, needing to be recut and pasted, easy waste and damage to the wall surface, and the higher price of PVC wall covering compared to lightweight PVC wallpaper.

[0015] As an optional solution of this utility model, the thin PVC coating is a layer structure formed by applying a slurry made of one or more of PVC resin, foaming agent, filler and plasticizer, stabilizer and flame retardant to the thin substrate layer, and the thickness of the thin PVC coating is 0.06-0.12mm.

[0016] As an optional solution of this utility model, the textured layer is a layer structure formed by high-temperature foaming and pressure roller pressing of the thin PVC coating, and the thickness of the textured layer is 0.08-0.15mm.

[0017] As an optional embodiment of this utility model, the thickness of the pattern layer is 0.01-0.02 mm, and the thickness of the local highlight layer is 0.01 mm.

[0018] As an optional solution of this utility model, it also includes an anti-mildew and antibacterial layer, which is disposed on the local high-gloss layer. The surface area of ​​the anti-mildew and antibacterial layer is the same as that of the thin substrate layer, and the thickness of the anti-mildew and antibacterial layer is 0.01 mm.

[0019] Based on the same inventive concept, this application also provides a decorative structure for a thin, three-dimensional wall covering, including:

[0038] like Figures 1-4 As shown, a lightweight, three-dimensional wallpaper 1 is provided, with a thickness of 0.1-0.3mm. The wallpaper includes:

[0039] Thin substrate layer 11;

[0040] A thin PVC coating 12 is disposed on the surface of a thin substrate layer 11.

[0041] Texture layer 13 is disposed on thin PVC coating 12;

[0042] Pattern layer 14 is set on texture layer 13;

[0043] A local highlight layer 15 is disposed on the pattern layer 14 and matches the embossing layer and / or the pattern layer 14.

[0044] The thin substrate layer 11 and the thin PVC layer are key components of the lightweight wallpaper, while the texture layer 13 and the localized high-gloss layer 15 are crucial for achieving a three-dimensional effect. Although the thin PVC coating combined with the texture layer 13 provides a basic embossed texture, its texture is weaker compared to ordinary PVC wallpaper. However, when combined with the localized high-gloss layer 15, the visual three-dimensional effect is enhanced. Therefore, the three-dimensional wallpaper obtained through this solution has a visual appearance comparable to ordinary PVC wallpaper, is overall thin, and its thickness is reduced by at least 50% compared to ordinary PVC wallpaper, making installation very convenient. In addition, this wallpaper is thinner than ordinary PVC wallpaper, resulting in a relatively low cost, making it very suitable for short-term indoor decoration projects such as exhibition halls, event venues, rental properties, and hotels.

[0045] Specifically, the thin substrate layer 11 is one of the following: wood pulp base paper layer, non-woven paper layer, non-woven fabric layer, cross-woven base layer, mesh fabric layer, and polyester fabric layer. The thickness of the thin substrate layer 11 is 0.02-0.15mm. Choosing a thin substrate layer within this thickness range can reduce the overall thickness of the wallpaper. An excessively thin substrate layer is prone to deformation or breakage due to tension, temperature, etc., during the preparation of three-dimensional wallpaper, resulting in a low yield rate. Preferably, the thickness of the thin substrate layer 11 is 0.1-0.15mm.

[0046] Specifically, the thin PVC coating 12 is a layer structure formed by applying a slurry made from PVC resin, foaming agent, filler, plasticizer, stabilizer, and flame retardant onto a substrate layer. The thickness of the thin PVC coating 12 is 0.06-0.12mm. Controlling the thickness of the thin PVC coating 12 to 0.06-0.12mm can further reduce the overall thickness of the wallpaper. It should be noted that the amount of foaming agent added to this thin PVC coating 12 should be reduced by 1 / 3 to 1 / 2 of the normal amount. This operation can reduce the foaming ratio of the slurry and achieve a micro-foaming effect.

[0047] Specifically, the texture layer 13 is a layer structure formed by high-temperature foaming and pressure roller pressing of the thin PVC coating 12. The thickness of the texture layer 13 is 0.08-0.15 mm. The texture layer 13 is mainly formed by increasing the thickness of the thin PVC coating 12 under high-temperature foaming, followed by the formation of a texture on the high-temperature foamed PVC coating by an embossing roller. The patterns that can be formed by the texture include, but are not limited to, textile textures, floral textures, etc., depending on the pattern engraving of the embossing roller. The thickness of the texture layer 13 depends on the texture thickness of the embossing roller and the thickness of the high-temperature foamed PVC coating. Generally, the thickness of the texture layer 13 is greater than the thickness of the thin PVC coating 12.

[0048] Specifically, the pattern layer 14 has a thickness of 0.01-0.02 mm, and the local highlight layer 15 has a thickness of 0.01 mm. The pattern layer 14 can be a layer structure formed by applying one or more inks. The combination of the local highlight layer 15, the pattern layer 14, and the texture layer 13 creates a good three-dimensional effect. Preferably, the local highlight layer 15 and the texture layer 13 are matched in design. For example, the local highlight layer 15 imitates the reflected light from a certain angle of light. Even if the three-dimensional effect of the texture layer 13 is small, a good three-dimensional effect can still be achieved, and it can still have a textured feel. Specifically, the local highlight layer 15 is mainly a layer structure obtained by printing a pearlescent paste, aluminum silver paste, or silver powder paste made of resin, additives, and mica powder of 1000 mesh or higher.

[0049] Specifically, the lightweight three-dimensional wallpaper 1 also includes an anti-mildew and antibacterial layer 16. The anti-mildew and antibacterial layer 16 is disposed on the locally high-gloss layer 15, and its size is the same as the upper surface area of ​​the lightweight substrate layer 11. The thickness of the anti-mildew and antibacterial layer 16 is 0.01 mm. The anti-mildew and antibacterial layer 16 is mainly a layer structure formed by laminating a slurry of resin, anti-mildew and antibacterial agent, and additives onto the surface of the locally high-gloss layer 15 and drying it. Preferably, the resin is one or more of PVC resin, acrylic resin, and polyurethane resin. The anti-mildew and antibacterial agent is preferably an organometallic compound antibacterial agent or an isothiazolone derivative antibacterial agent. Additives include leveling agents, emulsifiers, stabilizers, and wetting agents. When encountering relatively dark and damp spaces, setting an anti-mildew and antibacterial layer 16 on the surface of the thin and three-dimensional wall covering 1 can achieve good anti-mildew and antibacterial effects. In some embodiments, the thin and three-dimensional wall covering 1 has good anti-mildew and antibacterial performance, specifically achieving a level 0 anti-mildew effect (test method according to GB / T 34844-2017), and an anti-Escherichia coli and Staphylococcus aureus rate of 99% (test method according to JIS Z 2801:2012).

[0050] A decorative structure for a lightweight, three-dimensional wall covering 1, comprising:

[0051] Flat wall surface 2, wherein flat wall surface 2 includes linear corners;

[0052] Waterproof base film layer 3 is applied to the surface of the flat wall surface 2.

[0053] Ordinary wallpaper adhesive layer 4 is applied to the surface of waterproof base film layer 3;

[0054] Thin and three-dimensional wall covering 1 is applied to the surface of ordinary wallpaper adhesive layer 4.

[0055] Smooth wall surfaces 2 mainly include wall surfaces formed by granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, ceramic tiles, mosaics, natural stone, fiber gypsum board, magnesium oxide board, calcium silicate board, steel, aluminum, copper alloys, metal composite panels, etc.

[0056] When encountering linear corners on a wall, such as internal corners (21), external corners (22), or edges where boards are directly joined, ordinary PVC wall coverings are prone to bubbling at these corners when glued with ordinary wallpaper adhesive, leading to decorative problems. However, lightweight, three-dimensional wall coverings (1), due to their thinness, install more smoothly, and bubbling is rarely encountered even when using ordinary wallpaper adhesive at linear corners.

[0057] The waterproof base film layer 3 is mainly composed of a base film (water-based varnish) with waterproof effect. After drying, its surface has a fine uneven structure, which is conducive to the adhesion of the subsequent thin and three-dimensional wall covering 1.

[0058] The installation of the lightweight, three-dimensional wall covering 1 can be completed using ordinary wallpaper glue.

[0059] This lightweight, three-dimensional wall covering 1 is applied to a flat wall surface 2 using ordinary wallpaper adhesive, achieving a B1-level flame retardant effect. Because this lightweight wall covering produces little combustible gas and minimal smoke during thermal decomposition, according to GB 8624-2012, when applied to a flat wall surface 2, almost no flame spread occurs during testing, demonstrating a good flame retardant effect in the flame retardant test.
