Description

Technical Field

[0001] The utility model relates to a press-type luminous reflective film, belonging to the technical field of reflective materials. Background Art

[0002] Reflective film is a kind of reflective material widely used in traffic signs, safety clothing, outdoor advertising and other fields. Traditional reflective film usually needs to be under a specific light source to produce a reflective effect, and the reflective effect is weak and cannot meet the needs of some special scenes. This kind of reflective film generally needs to produce a reflective function under the irradiation of an external light source, but it cannot play a good reflective warning function when used in some unlit or dark environments. Therefore, some reflective films with luminous or light-storing functions have appeared on the market, making the reflective films on the market reflective films and luminous reflective films. At present, the luminescent materials in the luminescent films are mainly coated with photo-storage long afterglow materials, such as zinc sulfide luminescent materials and rare earth activated alkaline earth metal aluminate luminescent materials. This type of luminescent material mainly absorbs and stores the light energy of sunlight and light, and then releases energy to emit light in a dark environment. This kind of luminous reflective film is also widely used in emergency instructions, signs and logos. However, the above-mentioned luminescent materials are mainly realized by energy absorption after light irradiation, which is relatively simple. If it is used for too long in an environment without light, it will also affect its use effect. In addition, there is a certain delay and slow response when emitting light through external light sources. At the same time, considering that there is no functional product in the reflective film that can achieve luminescence by external pressing, it is completely necessary to conduct more functional property research on the reflective film to develop more reflective materials. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems existing in the prior art and to propose a press-type luminous reflective film to solve the problems of the single function of luminescence and untimely response of the prior art which only emits light through light irradiation.

[0004] The purpose of the utility model is achieved through the following technical solutions: a luminous reflective film, the reflective film includes a surface layer, a reflective layer and a substrate layer, characterized in that the reflective film also includes a light-transmitting press-on luminous layer, one side of the press-on luminous layer is bonded to the surface layer, and the other side of the press-on luminous layer is bonded to the reflective layer; the substrate layer includes an elastic deformation resin layer and a pressure-sensitive adhesive layer, and the elastic deformation resin layer is located between the reflective layer and the pressure-sensitive adhesive layer.

[0005] By making a new improvement design on the film layer structure of the reflective film, a press-on luminous layer is provided between the surface layer and the reflective layer, and the base material layer includes an elastic deformation resin layer and a pressure-sensitive adhesive layer, and the elastic deformation resin layer is located on the other side of the reflective layer. In this way, when the reflective film is required to emit light for warning or indicators, the reflective film can be pressed, so that the press-on luminous layer can realize the function of luminescence under the condition of force, which is equivalent to realizing the luminous function of the reflective film through the action of mechanical external force (pressing), and has the effect of fast response speed; at the same time, the press-on luminous layer and the elastic deformation resin layer are respectively located on both sides of the luminous film, so that when the reflective film is pressed, the press-on luminous layer and the reflective layer will form a partial press depression toward the elastic deformation resin layer side, and the depressed part formed by pressing can be used to make the depressed part of the press-on luminous layer emit light after being pressed, and under the reflective action of the reflective layer at the depressed part, the overall luminous and reflective effect is more obvious, thereby more effectively playing the function of luminous and reflective warning and / or identification. In addition, the use of a light-transmitting press-on luminous layer on one side of the luminous layer does not affect the reflective performance of the reflective layer under light irradiation, thereby achieving the diversity of the overall functions of the reflective film.

[0006] In the above-mentioned luminous reflective film, the press-on luminous layer includes a plurality of press-on luminous fiber material coatings, and the press-on luminous fiber material coatings are arranged at intervals along the length direction of the reflective film. This is equivalent to coating the above-mentioned press-on luminous fiber material coating between the reflective layer and the surface layer to form a distributed structure arranged at intervals, so that when the reflective film is subjected to external pressure, the coating emits light due to the external force, and the luminous layers distributed between adjacent press-on luminous fiber material coatings can also ensure that the reflective film can still form the function of a reflective warning and indicator under lighting conditions. The material of the above-mentioned press-on luminous fiber material coating is also a known material, which is mainly applied to the reflective film as a structural layer of the coating, and is not an improvement on the material.

[0007] In the above-mentioned luminous reflective film, as another preferred embodiment, the press luminescent layer is an organic rare earth lanthanum luminescent material coating. The organic rare earth lanthanum luminescent material coating itself is a coating made of a known organic rare earth lanthanum luminescent material coating. The present reflective film mainly applies the known material coating to the coating of the reflective film. When the reflective film is subjected to mechanical force such as external pressure, the press luminescent layer is subjected to pressure, so that the material of the organic rare earth lanthanum luminescent coating undergoes energy level transition, from a stable state to an excited state, and when the material subsequently changes from an excited state back to a stable state, the energy is converted into light energy to emit light.

[0008] In the above-mentioned luminous reflective film, the reflective layer includes a micro-prism structure layer and an acrylic resin layer, one side surface of the micro-prism structure layer is adhered to the pressed luminous layer, and the other side surface of the micro-prism structure layer is adhered to the acrylic resin layer. One side surface adhesiveThe other side of the acrylic resin layer is adhered to the surface of the elastic deformation resin layer. The micro-prismatic structure layer has a better reflective performance, so that the reflective film as a whole has a high luminous efficiency effect. As a further preferred embodiment, the thickness of the micro-prismatic structure layer is 320 μm to 350 μm.

[0009] In the above-mentioned luminous reflective film, the thickness of the pressed luminous layer is 30 μm to 45 μm.

[0010] In the above-mentioned luminous reflective film, the thickness of the elastic deformation resin layer is 250 μm to 280 μm.

[0011] In the above-mentioned luminous reflective film, a release paper layer is also provided on the surface of the pressure-sensitive adhesive layer to protect the viscosity of the pressure-sensitive adhesive and prevent it from being polluted by the external environment. When in use, it is only necessary to tear off the release paper layer.

[0012] Compared with the prior art, this luminous reflective film has the following advantages:

[0013] 1. The reflective film has a press-light emitting layer between the surface layer and the reflective layer, which is equivalent to realizing the luminous function of the reflective film through the action of mechanical external force (pressing), and realizes the self-luminous function of the reflective film.

[0014] 2. By locating the pressed luminous layer and the elastic deformable resin layer on both sides of the luminous film respectively, when pressing the reflective film, the pressed luminous layer and the reflective layer will form a partial pressing depression toward the elastic deformable resin layer side. The depressed area formed by pressing can be utilized to make the pressed luminous layer be illuminated by the luminous layer in the depressed area, so that the overall luminous and reflective effects are more obvious, thereby more effectively playing the role of luminous and reflective warning and identification.

DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] Example 1

[0020] Combination Figure 1 and Figure 2 As shown, the luminous reflective film includes a surface layer 1, a reflective layer 3 and a base layer 4. More importantly, the reflective film also includes a light-transmitting press-type luminous layer 2, one side of the press-type luminous layer 2 is bonded to the surface layer 1, and the other side of the press-type luminous layer 2 is bonded to the reflective layer 3; and the above-mentioned base layer 4 includes an elastic deformable resin layer 41 and a pressure-sensitive adhesive layer 42, and the elastic deformable resin layer 41 is located between the reflective layer 3 and the pressure-sensitive adhesive layer 42. The materials used in each layer of the above-mentioned reflective film are all known materials. The reflective film is mainly improved by improving the structure of the film layer, that is, by providing a press-on luminous layer 2 in the reflective film and making the layer between the surface layer 1 and the luminous layer 3, and at the same time, providing an elastic deformation resin layer 41 in the base material layer 4, so as to improve the structure, so that when the reflective film is pressed by an external force, the press-on luminous layer 2 can emit light, thereby playing a luminous characteristic, and at the same time, the light-transmitting film layer used in this layer does not affect the reflective performance of the reflective layer 3 below, and when irradiated by external sunlight or light, it can reflect light, realize the luminous and reflective functions of the reflective film, and improve the application range of the reflective film. When in use, such as in a dark environment, the reflective film can be pressed to realize its luminous function, and play a warning, indication and identification function, and has a certain lighting function. The press-on luminous layer 2 is formed by a coating of a known press-on luminous material.

[0021] Combination Figure 2 As shown, the above-mentioned press-on luminous layer 2 includes a plurality of press-on luminous fiber material coatings 21, and the press-on luminous fiber material coatings 21 are arranged at intervals along the length direction of the reflective film. Similarly, here, it is mainly through the adjustment of the structure. The distribution of the press-on luminous fiber material coatings 21 is arranged at equal intervals. The press-on luminous fiber material coatings 21 can be a strip-shaped structure. For example, if the reflective film is rectangular, the press-on luminous fiber material coatings 21 can be distributed at intervals along its length direction, and the strip-shaped press-on luminous fiber material coatings 21 run through the width of the reflective film to form a strip-shaped spaced distribution structure. In addition, the press-on luminous fiber material itself is a known material, such as the press-on luminous layer material disclosed in the existing Chinese patent (CN115726193B). Further, for the interval area between two adjacent press-on luminous fiber material coatings 21, a transparent acrylic resin material can be used to fill it, or the surface layer 1 can be located on the side of the press-on luminous layer 2. The interval between the two press-on luminous fiber material coatings 21 is filled. Of course, the entire press-to-light emitting layer 2 may also be coated with the press-to-light emitting fiber material coating material. Since it is a light-transmitting material, it can also realize the press-to-light emitting and light-reflecting functions.

[0022] In a further preferred embodiment, the reflective layer 3 comprises a micro-prismatic structure layer 31 and an acrylic resin layer 32, one side surface of the micro-prismatic structure layer 31 is adhered to the pressed light-emitting layer 2, the other side surface of the micro-prismatic structure layer 31 is adhered to one side surface of the acrylic resin layer 32, and the other side surface of the acrylic resin layer 32 is adhered to the surface of the elastic deformation resin layer 41. It is preferred that the thickness of the micro-prismatic structure layer 31 is 320 μm to 350 μm, preferably 330 μm.

[0023] It is best to make the thickness of the above-mentioned press-on luminous layer 2 30μm to 45μm. This can ensure the function of press-on luminous layer 2, and at the same time make the thickness of the press-on luminous layer 2 relatively thin, which is more conducive to its change with the deformation of the elastic deformation resin layer 41 when pressed. Of course, it is best to make the thickness of the above-mentioned elastic deformation resin layer 41 250μm to 280μm, preferably 260μm; and the surface of the above-mentioned pressure-sensitive adhesive layer 42 can also be provided with a release paper layer 5.

[0024] The material of the surface layer 1 can be formed of known polyurethane-modified acrylic resin, wherein the pressure-sensitive adhesive layer 42 is made of acrylic pressure-sensitive adhesive material. The thickness of the pressure-sensitive adhesive layer 42 can be further controlled to be 30μm to 40μm, and the thickness of the surface layer 1 can be controlled to be 55μm to 60μm.

[0025] Example 2

[0026] like Figure 1 As shown, the structure of the luminous reflective film in this embodiment is basically consistent with that in Embodiment 1, except that the pressing light layer 2 adopts the following structural design.

[0027] That is, as another alternative embodiment, the above-mentioned pressed luminescent layer 2 is an organic rare earth lanthanum luminescent material coating. The organic rare earth lanthanum luminescent material coating here is a coating of a known material. The other structural designs are basically consistent with Example 1 and will not be repeated here.

[0028] When in use, the release paper layer 5 outside the pressure-sensitive adhesive layer 42 of the luminous reflective film is torn off, and then the corresponding pressure-sensitive adhesive layer 42 is pasted on the corresponding carrier for use. The carrier here can be clothing that needs to be reflective, or it can be used on products such as traffic reflective signs.

[0029] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0030] Although the terms such as surface layer 1, pressed luminous layer 2, pressed luminous fiber coating 21, reflective layer 3, micro-prismatic structure layer 31, acrylic resin layer 32, substrate layer 4, elastic deformation resin layer 41, pressure-sensitive adhesive layer 42, release paper layer 5 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
