Description

Technical Field

[0001] This invention belongs to the field of reflective film technology, specifically relating to a reflective film with a fluorescent layer. Background Technology

[0002] Reflective film is a material widely used in traffic signs, billboards, safety warnings, and other fields. Its main function is to reflect light under illumination, thereby improving visibility at night or in low-light conditions. However, traditional reflective film has limited brightness at night or in low-light conditions, especially when there is no direct external light source, its reflective effect will decrease significantly. Furthermore, when scratches appear on the surface of reflective film, they cannot self-repair, thus affecting its appearance and lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a reflective film with a fluorescent layer, which solves the problems of insufficient brightness and easy scratching of traditional reflective films at night or under low light conditions.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A reflective film with a fluorescent layer includes a base layer, a metallic silver reflective layer bonded to the upper surface of the base layer, a composite fluorescent layer bonded to the upper surface of the metallic silver reflective layer, a nanoporous silica layer bonded to the upper surface of the composite fluorescent layer, a polymer diffusion layer bonded to the upper surface of the nanoporous silica layer, a microprism layer bonded to the upper surface of the polymer diffusion layer, and a diffuse reflection layer bonded to the upper surface of the microprism layer.

[0006] This invention is further configured such that the composite fluorescent layer comprises a rare-earth-doped phosphor layer, an organic fluorescent dye layer, a zinc sulfide-based phosphor layer, a quantum dot fluorescent material layer, and a long-afterglow phosphor layer. The bottom of the rare-earth-doped phosphor layer is bonded to the upper surface of the metallic silver reflective layer, the upper surface of the rare-earth-doped phosphor layer is bonded to the bottom of the organic fluorescent dye layer, the upper surface of the organic fluorescent dye layer is bonded to the bottom of the zinc sulfide-based phosphor layer, the upper surface of the zinc sulfide-based phosphor layer is bonded to the bottom of the quantum dot fluorescent material layer, the upper surface of the quantum dot fluorescent material layer is bonded to the bottom of the long-afterglow phosphor layer, and the upper surface of the long-afterglow phosphor layer is bonded to the bottom of the nanoporous silica layer.

[0007] The present invention is further configured such that an adhesive backing layer is bonded to the bottom of the base layer, and a silicone paper layer is bonded to the bottom of the adhesive backing layer.

[0008] The present invention is further configured such that a fluorocarbon resin layer is bonded to the upper surface of the diffuse reflection layer, and a wear-resistant coating is bonded to the upper surface of the fluorocarbon resin layer.

[0009] The present invention is further configured such that a light-curing resin layer is bonded to the upper surface of the wear-resistant coating, and a microcapsule repair agent layer is bonded to the upper surface of the light-curing resin layer.

[0010] The present invention is further configured such that a lubricating layer is adhered to the upper surface of the microcapsule repair agent layer.

[0011] The technical effects achieved by this utility model are as follows:

[0012] This invention discloses a reflective film with a fluorescent layer. The composite fluorescent layer comprises five layers of fluorescent materials, each corresponding to a different spectral band, enabling efficient absorption and emission across the entire spectrum. Simultaneously, a metallic silver reflective layer enhances the emission of weak light, allowing even weak light to be absorbed and utilized by the composite fluorescent layer. Furthermore, a polymer diffusion layer and a nanoporous silica layer uniformly disperse reflected light across the entire viewing angle, thereby improving the utilization rate of light energy by the composite fluorescent layer and ensuring uniform brightness of the emitting surface. Through the synergistic effect of the composite fluorescent layer, the nanoporous silica layer, the polymer diffusion layer, and the metallic silver reflective layer, the reflective film can achieve continuous emission across the entire spectrum at night or under low light conditions, significantly improving visibility in low-light environments.

[0013] This invention relates to a reflective film with a fluorescent layer. Through a microcapsule repair agent layer, the reflective film surface can automatically release epoxy resin repair agent after scratches appear, filling the damaged gaps. Furthermore, the light-curing resin layer can react with the epoxy resin repair agent and quickly cure under ultraviolet light to repair scratches. Thus, through the light-curing resin layer and the microcapsule repair agent layer, the reflective film has the function of automatically repairing scratches. At the same time, the lubrication layer can reduce the friction coefficient of the reflective film surface, thereby making the reflective film surface less prone to scratches.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] The composite fluorescent layer 3 includes a rare earth-doped phosphor layer 31, an organic fluorescent dye layer 32, a zinc sulfide-based phosphor layer 33, a quantum dot fluorescent material layer 34, and a long-afterglow phosphor layer 35. The bottom of the rare earth-doped phosphor layer 31 is bonded to the upper surface of the metallic silver reflective layer 2. The upper surface of the rare earth-doped phosphor layer 31 is bonded to the bottom of the organic fluorescent dye layer 32. The upper surface of the organic fluorescent dye layer 32 is bonded to the bottom of the zinc sulfide-based phosphor layer 33. The upper surface of the zinc sulfide-based phosphor layer 33 is bonded to the bottom of the quantum dot fluorescent material layer 34. The upper surface of the quantum dot fluorescent material layer 34 is bonded to the bottom of the long-afterglow phosphor layer 35. The upper surface of the long-afterglow phosphor layer 35 is bonded to the bottom of the nanoporous silica layer 4.

[0022] It should be noted that the material of the metallic silver emitting layer is metallic silver, which has a high reflectivity and can enhance the emission of weak light, so that weak light can also be absorbed and utilized by the composite fluorescent layer 3. The material of the nanoporous silica layer 4 is nanoporous silica, which can enhance light scattering and transmittance. The material of the polymer diffusion layer 5 is polymethyl methacrylate, which can distribute light evenly. The polymer diffusion layer 5 and the nanoporous silica layer 4 can evenly disperse the reflected light to the full viewing angle range, thereby improving the utilization rate of light energy of the composite fluorescent layer 3 and ensuring the uniformity of the brightness of the emitting surface.

[0023] Rare earth-doped phosphor layer 31 absorbs ultraviolet light and emits red light. The organic fluorescent dye layer 32 is made of Rhodamine B and emits green light to supplement the spectrum. The zinc sulfide-based phosphor layer 33 emits blue light, covering the entire visible light spectrum. The quantum dot fluorescent material layer 34 has broad spectral coverage and can adapt to complex light sources. The long-afterglow phosphor layer 35 can emit light continuously without a light source (afterglow effect). The microprism layer 6 can retroreflect light under strong light, enhancing the warning effect of light sources such as vehicle lights. The diffuse reflection layer 7 is made of titanium dioxide particle dispersion polymer and scatters light at all angles, improving the visibility of pedestrians.

[0024] like Figure 1 As shown, the bottom of the base layer 1 is bonded with an adhesive backing layer 8, and the bottom of the adhesive backing layer 8 is bonded with a silicone paper layer 9.

[0025] It should be noted that the material of the backing layer 8 is pressure-sensitive adhesive. The reflective film can be directly adhered to the object through the backing layer 8, and the silicone paper layer 9 can protect the backing layer 8.

[0027] It should be noted that the fluorocarbon resin layer 10 has strong UV resistance, which can prevent the reflective film from aging due to UV radiation. The wear-resistant coating 11 is made of silicon carbide nanoparticle modified resin, which can provide primary protection for the surface of the reflective film. The photocurable resin layer 12 is made of acrylic resin containing photoinitiator. The microcapsule repair agent layer 13 is made of urea-formaldehyde resin microcapsules containing epoxy resin repair agent. After scratches appear on the surface of the reflective film, the microcapsule repair agent layer 13 can automatically release epoxy resin repair agent to fill the damaged gaps. In addition, the photocurable resin layer 12 can react with the epoxy resin repair agent and cure quickly under ultraviolet light to repair scratches. The lubrication layer 14 is made of polysiloxane containing molybdenum disulfide nanosheets. The lubrication layer 14 reduces the surface friction coefficient, thereby making the surface of the reflective film less prone to scratches.
