Description

Technical Field

[0001] This utility model relates to the field of decorative film technology, and in particular to a decorative film with dual light reflection effect. Background Technology

[0002] Existing PVC decorative films with light-reflecting effects typically consist of a transparent PVC surface layer and a textured layer formed on the surface of the transparent PVC layer. However, the reflective effect of the textured layer is relatively simple, and the reflective effect does not change with the viewing angle when the viewing angle of the PVC decorative film changes, thus failing to achieve a good decorative effect.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] The present invention aims to provide a decorative film with dual light reflection effect, which solves the problem that the existing PVC decorative film with light reflection effect has a single reflective effect and cannot achieve a good decorative effect.

[0005] To achieve the above objectives, the solution provided by this utility model is as follows:

[0006] A decorative film with dual-light reflection effect includes a PVC substrate layer; the surface of the PVC substrate layer has a first textured area and a second textured area distributed alternately; the first textured area and the second textured area are simultaneously parallel to the length direction of the PVC substrate layer, or simultaneously parallel to the width direction of the PVC substrate layer; the first textured area has multiple sets of first textures, each set of first textures including multiple spaced first textured ridges; the second textured area has multiple sets of second textures, each set of second textures including multiple spaced second textured ridges; the two sides of the first textured ridges perpendicular to the PVC substrate layer are respectively a first mirror surface and a first frosted surface, and the two sides of the second textured ridges perpendicular to the PVC substrate layer are respectively a second mirror surface and a second frosted surface; the first mirror surface and the second mirror surface are inwardly V-shaped, and both the first mirror surface and the second mirror surface face the same side of the PVC substrate layer.

[0007] Optionally, the surface roughness of the first mirror and the second mirror is 0.1 to 0.3 μin; the surface roughness of the first frosted surface and the surface roughness of the second frosted surface is 30 to 50 μin.

[0008] Optionally, the surface of the PVC substrate layer is further provided with a transition texture area, which is located between the first texture area and the second texture area. Multiple sets of third textures are distributed on the transition texture area, and each set of third textures includes multiple spaced third texture protrusions. The two ends of the third texture protrusions extend to the first texture area and the second texture area respectively in a direction parallel to the first texture protrusion and a direction parallel to the second texture protrusion. The two sides of the third texture protrusions perpendicular to the PVC substrate layer are respectively a third mirror surface and a third frosted surface. The third mirror surface and the first mirror surface both face the same side of the PVC substrate layer.

[0009] Optionally, the surface roughness of the third mirror surface is 0.1 to 0.3 μin; the surface roughness of the third frosted surface is 30 to 50 μin.

[0010] Optionally, the thickness of the first textured ridge, the second textured ridge, and the third textured ridge is 10 to 50 μm.

[0011] Optionally, the first textured ridge, the second textured ridge, and the third textured ridge are roll-formed on the surface of the PVC substrate layer.

[0012] Optionally, the decorative film with dual-light reflection effect may also include a back coating layer connected to the back of the PVC substrate layer.

[0013] Optionally, the PVC substrate layer comprises, from top to bottom, a PVC surface layer, an ink printing layer, a PVC printed substrate layer, and a PVC bottom layer; the PVC bottom layer is connected to the back coating layer.

[0014] Beneficial effects:

[0015] This invention provides a decorative film with a dual-light reflection effect. By embossing the surface of a PVC substrate layer, a first textured area with a first textured ridge and a second textured area with a second textured ridge are sequentially and alternately distributed on the surface of the PVC substrate layer. The first and second textured ridges can produce specular reflection and diffuse reflection with different reflection directions. At the same time, the specular reflection direction of the first textured area is consistent, and the specular reflection direction of the second textured area is consistent. Therefore, when the viewing angle changes, the reflection effect also changes with the movement of the viewing angle, so that the first and second textured areas present a dual visual phenomenon of alternating brightness and darkness, that is, a dual visual phenomenon combining light and dark. Thus, the surface pattern of the decorative film is more flexible and vivid, giving people a dazzling feeling and having a good decorative effect.

[0016] The decorative film with bi-light reflection provided by this utility model can be used not only in the field of furniture decoration, but also in the fields of optics, electronics, and packaging. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] It should also be noted that when a component is referred to as "fixed to" or "attached to" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0032] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0033] like Figures 1 to 5 As shown, this utility model provides a decorative film with a dual-light reflection effect, which includes a PVC substrate layer 1. The surface of the PVC substrate layer 1 is sequentially and alternately distributed with first textured areas A (…). Figure 1 The rectangular area containing the letter A) and the second texture area B. Figure 1 (The rectangular area where the letter B is located). The first textured area A and the second textured area B are both parallel to the length direction of the PVC substrate layer 1, or both parallel to the width direction of the PVC substrate layer 1. Further, the first textured area A has multiple sets of first textures 2, and the second textured area B has multiple sets of second textures 3. Each set of first textures 2 includes multiple spaced and parallel or nearly parallel first texture ridges 21, and each set of second textures 3 includes multiple spaced and parallel or nearly parallel second texture ridges 31. The first textured ridge 21 has a first mirror surface 211 and a first frosted surface 212 on both sides perpendicular to the PVC substrate layer 1, and the second textured ridge 31 has a second mirror surface 311 and a second frosted surface 312 on both sides perpendicular to the PVC substrate layer 1; the included angle A between the first mirror surface 211 and the second mirror surface 311 is 130° to 150°, that is, the first mirror surface 211 and the second mirror surface 311 are inward V-shape, and the first mirror surface 211 and the second mirror surface 311 both face the same side of the PVC substrate layer 1.

[0034] When light shines on the surface of the PVC substrate layer 1, the light undergoes specular reflection on the first mirror surface 211 and the second mirror surface 311, resulting in a high-brightness reflection effect. Conversely, the light undergoes diffuse reflection on the first frosted surface 212 and the second frosted surface 312, resulting in a low-gloss effect. Because the first mirror surface 211 and the second mirror surface 311 are V-shaped and both face the same side of the PVC substrate layer 1, the specular reflection direction on the first textured area A differs from that on the second textured area B. When the observer's field of vision falls on the first textured area A, the first textured area A exhibits a high-gloss effect, while the second textured area B exhibits a low-gloss effect. Since the first textured area A and the second textured area B are alternately distributed on the surface of the PVC substrate layer 1, the reflective effect changes with the viewing angle when the viewing angle changes. This results in a dual visual phenomenon where the first textured area A and the second textured area B appear to be sometimes bright and sometimes dark, and sometimes dark and sometimes bright. The surface of the decorative film can give people a dazzling feeling and has a good decorative effect.

[0035] Optionally, the surface roughness of the first mirror 211 and the second mirror 311 is 0.1 to 0.3 μin; the surface roughness of the first frosted surface 212 and the second frosted surface 312 is 30 to 50 μin. The first mirror 211 and the second mirror 311 with a surface roughness of 0.1 to 0.3 μin have relatively smooth and flat surfaces. When light shines on the first mirror 211 and the second mirror 311, it can produce regular mirror reflection and form a high-brightness reflection effect. On the other hand, the first frosted surface 212 and the second frosted surface 312 with a surface roughness of 30 to 50 μin have relatively rough surfaces. When light shines on the first frosted surface 212 and the second frosted surface 312, it will scatter in different directions and produce diffuse reflection, thus presenting a low-gloss effect. This difference in surface roughness due to the textured ridges results in a significant combination of light and dark in the first textured area A and the second textured area B, creating a dual visual phenomenon.

[0036] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, optionally, the surface of the PVC substrate layer 1 is further provided with a transition texture area, which is located between the first texture area A and the second texture area B, and multiple sets of third textures 4 are distributed on the transition texture area. Each set of third textures 4 includes multiple spaced third texture protrusions 41. The two ends of the third texture protrusions 41 extend to the first texture area A and the second texture area B in a direction parallel to the first texture protrusion 21 and a direction parallel to the second texture protrusion 31, respectively. The two sides of the third texture protrusions 41 perpendicular to the PVC substrate layer 1 are respectively a third mirror surface 411 and a third frosted surface 412. The third mirror surface 411 and the first mirror surface 211 both face the same side of the PVC substrate layer 1.

[0037] By setting a transition texture area between each first texture area A and second texture area B, and extending the two ends of the third texture ridge 41 on the transition texture area along the direction parallel to the first texture ridge 21 and the direction parallel to the second texture ridge 31 to the first texture area A and the second texture area B respectively, when the third texture ridge 41 has a third mirror 411 with the same orientation as the first mirror 211 and the second mirror 311, the connection of the brightness and darkness of the first texture area A and the second texture area B can be realized, that is, a gradual change in gloss can be realized between the first texture area A and the second texture area B.

[0038] Optionally, the surface roughness of the third mirror surface 411 is 0.1–0.3 μin; the surface roughness of the third frosted surface 412 is 30–50 μin. By making the surface roughness range of the third mirror surface 411 consistent with that of the first mirror surface 211 and the second mirror surface 311, and the surface roughness range of the third frosted surface 412 consistent with that of the first frosted surface 212 and the second frosted surface 312, when the two ends of the third textured ridge 41 extend towards the first textured area A and the second textured area B respectively, a gradual change in gloss can be achieved between the first textured area A and the second textured area B, realizing a natural connection between the light and dark changes of the two, avoiding visual abruptness, making the visual effect of the decorative film surface softer and more natural, and further enhancing the decorative effect of the decorative film.

[0039] Optionally, the first textured ridge 21, the second textured ridge 31, and the third textured ridge 41 are roll-formed on the surface of the PVC substrate layer 1. By designing the concave texture on the surface of the roller (such as a ceramic roller), it is possible to ensure that the textured ridges formed on the surface of the PVC substrate layer 1 have high dimensional accuracy and regular shape, thereby achieving a stable bi-light reflection effect on the decorative film surface. This ensures the quality stability of PVC film products with bi-light reflection effect and enhances the market competitiveness of such products.

[0040] Optionally, the thickness of the first textured ridge 21, the second textured ridge 31, and the third textured ridge 41 are all 10-50 μm. Controlling the thickness of each textured ridge within this range ensures that the textured ridges possess sufficient physical strength, preventing deformation or damage due to external forces (such as friction or compression) during actual use. This maintains the integrity of the surface texture structure of the decorative film, ensuring a stable dual-light reflection effect and good decorative performance over long-term use. Furthermore, the aforementioned thickness range of the textured ridges helps achieve an ideal light reflection effect. If the textured ridges are too thin, the reflection and scattering of light on the mirror and frosted surfaces will be affected, failing to create a significant difference between specular and diffuse reflection, resulting in an insignificant dual-light reflection effect and an inability to present a dazzling visual effect.

[0041] like Figure 2 and Figure 3 As shown, optionally, the decorative film with bi-reflective effect also includes a back coating layer 5 connected to the back of the PVC substrate layer 1. The back coating layer 5 allows the decorative film, including the PVC substrate layer 1, to adhere to the surface of the object, enabling the bi-reflective decorative film to better fit the surface of the object and preventing the decorative film from falling off or peeling during use.

[0042] like Figure 2 and Figure 3 As shown, optionally, the PVC substrate layer 1 includes, from top to bottom, a PVC surface layer 101, an ink printing layer 102, a PVC printing substrate layer 103, and a PVC bottom layer 104; the PVC bottom layer 104 is connected to the back coating layer 5. The ink printing layer 102 can be an ink printing layer 102 with a printed pattern, or it can be an ink printing layer 102 with a single color. The setting of the ink printing layer 102 makes the pattern on the surface of the decorative film more flexible and vivid, and, combined with the texture of the surface of the decorative film, can give people a dazzling feeling.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
