Description

Technical Field

[0001] The utility model relates to a reflective heat patch, belonging to the technical field of reflective materials. Background Art

[0002] The reflective heat patch is attached to a corresponding fabric or other carrier after heating. By using the principle of reflection formed by the reflective layer in the reflective heat patch, the product exhibits excellent reflective effects and realizes the functions of warning, indication, and reminder. Here, the reflective heat patch can also be applied to products such as the commonly mentioned reflective warning tapes. For example, in a relatively dark environment at night or in places where stage effects are required, such as various traffic warning, indication, and reminder function products like highway and railway guide signs, indicator signs, contour markers, traffic cones, and billboards; it can also be applied in mining environments or concert site lighting effects. However, currently, the commonly used reflective heat patches are either relatively single in function. Mainly, a reflective layer with a reflective function is adhered to the surface, such as adhering a glass bead reflective layer or a microprism reflective layer to achieve the reflective function. However, products with only a reflective function mainly utilize the external light source irradiating its surface to form a reflective effect, and are limited in application in some environments without an external light source or with dim light. Some also adopt a design method of adding a fluorescent material layer and other integral layer structures between the reflective layer and the hot melt adhesive layer. However, although this method can improve the performance of the function, since the corresponding color display layer is formed by integral coating and buried under the reflective layer, on the one hand, the overall material consumption is large, which is not conducive to cost control. Some, such as the twill reflective warning heat patch disclosed in Chinese Patent (CN213904834U), can set a color display layer in the reflective heat patch and set a glass bead reflective layer on the surface of the color display layer. The color display layer adopts different color display areas to achieve a reflective visual effect with multiple color distributions to enhance the warning function. However, it still only utilizes the reflective function and cannot play its reflective warning function in a dark environment or an environment without light, and there are still problems with fewer functions in the light display method. Summary of the Invention

[0003] The purpose of the utility model is to address the above problems existing in the prior art and propose a reflective heat patch to solve how to diversify the functions of the reflective heat patch and facilitate cost reduction.

[0004] The object of the present utility model is achieved by the following technical solutions: A reflective heat patch, the reflective heat patch includes a body, a carrier film layer is attached to one side surface of the body, the body includes a hot melt adhesive layer and a reflective layer, the body further includes a light storage layer and a fluorescent layer, the reflective layer, the light storage layer and the fluorescent layer are all bonded to the same side surface of the hot melt adhesive layer through an adhesive layer, the reflective layer is arranged along the length direction of the hot melt adhesive layer and is located on the middle surface of this side, the light storage layer and the fluorescent layer are arranged on both sides of the reflective layer along the width direction of the hot melt adhesive layer, and the reflective layer, the light storage layer and the fluorescent layer are all located between the adhesive layer and the carrier film layer.

[0005] By improving the overall structure of this reflective heat patch, the reflective layer, the light storage layer and the fluorescent layer are jointly bonded to the same side surface through the adhesive layer directly on the surface of the hot melt adhesive layer, which can better avoid material waste under the reflective layer and is conducive to better cost control; at the same time, more importantly, by bonding the reflective layer, the light storage layer and the fluorescent layer to the same side surface at the same time and arranging the light storage layer and the fluorescent layer on both sides of the reflective layer located in the middle, the effect of realizing multiple functions can be effectively achieved. In a dim environment or at night, under the condition of light, the reflective effect of the reflective layer can be used to realize the functions of warning, indicating and reminding. In a dark environment without light, the light storage ability of the light storage layer can be used to enable it to realize the function of self-luminescence; and the fluorescent layer can produce a fluorescent effect under the irradiation of light. Overall, the multifunctional effects of reflection, self-luminescence and fluorescence are realized, and the processing cost can also be better controlled. It has the advantages of diverse functions and better reduction of processing cost, and is more conducive to industrial production.

[0006] In the above-mentioned reflective heat patch, the positions of the light storage layer and the fluorescent layer on both sides of the reflective layer can be set according to the situation. For example, the positions of the light storage layer and the fluorescent layer on each side can be changed, or the two sides can be arranged asymmetrically. To better achieve the above effects, as a further preference, it is preferably that the light storage layer on each side is located between the reflective layer and the fluorescent layer. This can make the positions of the light storage layer and the fluorescent layer on both sides of the reflective layer the same, achieving a better symmetrical effect. At the same time, making the light storage layer located between the fluorescent layer and the reflective layer can better protect the material properties of the light storage layer, avoid excessive exposure of the edge of the light storage layer on the outside, and is conducive to better achieving the light storage effect. On the other hand, making the fluorescent layer located on the outside can better display the edge effect of the reflective heat patch when the fluorescent layer emits light.

[0007] In the above-mentioned reflective heat patch, as a further preference, the adjacent edges of each side of the light storage layer and the fluorescent layer are aligned and laminated; and the adjacent edges of the reflective layer and each side of the light storage layer are aligned and laminated, and the outer edges of the fluorescent layer and the hot melt adhesive layer are aligned. That is to say, each layer is closely aligned and laminated together in sequence, and the adjacent edges of each are continuously distributed in a laminated manner, improving the overall continuity and aesthetics.

[0008] In the above-mentioned reflective heat patch, a plurality of strip-shaped hollow grooves are further spaced along the length direction of the body. Both ends of the length direction of the hollow groove penetrate through the edge of the body, and the length direction of the body is arranged crosswise with the length direction of the hollow groove. In this way, when the reflective heat patch is used, due to the setting of the hollow groove, the air permeability effect can be improved, enabling it to be better applied to different substrates. As a further preference, the hollow grooves are inclined and arranged at equal intervals, and the distance of each hollow groove along the length direction of the body is less than the interval distance between adjacent two hollow grooves.

[0009] In the above-mentioned reflective heat patch, the width of the fluorescent layer is greater than the width of the light storage layer, and the width of the reflective layer is greater than the width of the fluorescent layer. This is mainly because the reflective layer and the fluorescent layer achieve the reflective and fluorescent effects by using light. By making the fluorescent layer and the reflective layer occupy a larger display range, the reflective and fluorescent effects can be better achieved; while the light storage layer utilizes its own light-emitting characteristics, making it occupy a relatively smaller distribution range, which can not only achieve its self-reflective effect, but also better exert the maximum effects of reflection and fluorescence, and better ensure its multi-functional effects of reflection, light storage and fluorescence.

[0010] In the above-mentioned reflective heat patch, a release paper layer is also adhered to the other surface of the body. This is mainly used to protect the surface quality and adhesiveness of the hot melt adhesive layer on this side.

[0011] Compared with the prior art, the present highly weather-resistant reflective film has the following advantages:

[0012] 1. By directly bonding the reflective layer, the light storage layer and the fluorescent layer together on the same side surface through the adhesive layer on the surface of the hot melt adhesive layer, the waste of materials located below the reflective layer is effectively avoided, which is beneficial to better cost control; at the same time, more importantly, the present reflective heat patch bonds the reflective layer, the light storage layer and the fluorescent layer on the surface at the same time, and makes the light storage layer and the fluorescent layer distributed on both sides of the reflective layer located in the middle, which can effectively achieve the effect of displaying multiple functions.

[0013] 2. By allowing the fluorescent layer and the reflective layer to occupy a relatively large display area, the reflective and fluorescent effects can be better achieved. By allowing the energy storage layer to occupy a relatively small distribution area, not only can its self-reflective effect be realized, but also the maximum reflective and fluorescent effects can be better exerted, ensuring its multi-functional effects of reflection, energy storage, and fluorescence.

[0019] The following are specific embodiments of the present utility model in combination with the accompanying drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0020] Embodiment 1

[0021] Combined with Figure 1As shown in the figure, this reflective heat patch includes a body 1, and a carrier film layer 2 is attached to one side surface of the body 1. The body 1 includes a hot melt adhesive layer 11 and a reflective layer 12. More importantly, the body 1 further includes a phosphorescent layer 13 and a fluorescent layer 14. The reflective layer 12, the phosphorescent layer 13, and the fluorescent layer 14 are all adhered to the same side surface of the hot melt adhesive layer 11 through an adhesive layer 15. The reflective layer 12 is arranged along the length direction of the hot melt adhesive layer 11 and is located on the middle surface of this side. On both sides of the reflective layer 12 along the width direction of the hot melt adhesive layer 11, there are arranged the phosphorescent layer 13 and the fluorescent layer 14. The reflective layer 12, the phosphorescent layer 13, and the fluorescent layer 14 are all located between the adhesive layer 15 and the carrier film layer 2. Making the three layers located between the adhesive layer 15 and the carrier film layer 2 is equivalent to making the outer surface of the body 1 on the side of the reflective layer 12, the phosphorescent layer 13, and the fluorescent layer 14 be attached with the carrier film layer 2, and the carrier film layer 2 covers the entire surfaces of the reflective layer 12, the phosphorescent layer 13, and the fluorescent layer 14. Making the above-mentioned reflective layer 12, phosphorescent layer 13, and fluorescent layer 14 be jointly located on the same side surface of the hot melt adhesive layer 11, and making the phosphorescent layer 13 and the fluorescent layer 14 be distributed outward from both sides of the reflective layer 12 located in the middle is equivalent to a structural arrangement where the three layers are distributed on the same layer. In this way, a multi-functional display effect can be achieved, and there is no need to adopt a stacked manner with each layer distributed, which is also beneficial for better cost control. For the above-mentioned reflective heat patch, the carrier film layer 2 on its surface can be covered with transparent film materials such as PET film or PET / PP composite film, and the material of the hot melt adhesive layer 11 can be PES hot melt adhesive material or TPU hot melt adhesive material, etc. The above-mentioned adhesive layer 15 can also be a color separation adhesive layer structure formed by coating with a color separation adhesive material, which can have the effect of color separation while playing a bonding role.

[0022] In a further embodiment, the positional distribution of the energy storage layer 13 and the fluorescent layer 14 on each side of the reflective layer 12 can be adjusted as needed. For example, the outermost layer can be the fluorescent layer 14, or it can be the energy storage layer 13. It is also possible that the energy storage layer 13 and the fluorescent layer 14 on both sides of the reflective layer 12 are symmetrically or asymmetrically arranged on both sides. It is also possible to have an intermittent distribution between the energy storage layer 13 and the fluorescent layer 14 or a closely arranged manner where they are aligned and compounded in sequence. To better achieve the above functions, in this embodiment, corresponding settings are made on both sides of the reflective layer 12, and the energy storage layer 13 on each side is located between the reflective layer 12 and the fluorescent layer 14. At the same time, as a more optimal embodiment, in this embodiment, the adjacent edges of the energy storage layer 13 and the fluorescent layer 14 on each side are aligned and compounded; and the adjacent edges of the reflective layer 12 and the energy storage layer 13 on each side are aligned and compounded, and the outer edge of the fluorescent layer 14 is aligned with the outer edge of the hot melt adhesive layer 11. The above alignment and compounding is equivalent to aligning and adhering the edges of the corresponding reflective layer 12 and the energy storage layer 12 on the corresponding side together to form a tight bonding relationship. Similarly, the edges of the energy storage layer 13 and the fluorescent layer 14 on the corresponding side are aligned and adhered to form a compounded integral manner, so that the reflective layer 12, the energy storage layer 13, and the fluorescent layer 14 form a continuous distribution manner, and there is no spaced area between adjacent layers, but they are tightly adhered together. This can improve the overall aesthetics and also ensure the continuity of the connection between the fluorescent layer 14, the energy storage layer 13, and the reflective layer 12 of this layer.

[0023] Preferably, the width of the above fluorescent layer 14 is greater than the width of the energy storage layer 13, and the width of the reflective layer 12 is greater than the width of the fluorescent layer 14. Further, a release paper layer 3 is also attached to the surface of the body 1 on the side of the hot melt adhesive layer 11. This is equivalent to attaching the above release paper layer 3 to the outer surface of the melt adhesive layer 11. The setting of this release paper layer 3 can protect the surface quality; during use, it only needs to be torn off.

[0024] Embodiment 2

[0025] Combined with Figures 2-4 As shown, the structure of the reflective heat patch in this embodiment is basically the same as that in Embodiment 1. The difference is that on the basis of the structure of the above reflective heat patch, corresponding hollow grooves 16 are also provided in the structure of the body 1, which will be specifically described as follows:

[0026] As Figure 2 and Figure 3As shown, a plurality of strip-shaped hollow grooves 16 are also arranged at intervals along the length direction of the body 1. Both ends of the hollow groove 16 in the length direction penetrate through the edge of the body 1, and the length direction of the body 1 is arranged crosswise with the length direction of the hollow groove 16. That is, the length direction of each hollow groove 16 is not parallel to the length direction of the body 1, or is arranged in an inclined or vertical manner to form a certain included angle, which can better improve the air permeability effect. Combining Figure 3 and Figure 4 As shown, it is preferably that the above-mentioned hollow grooves 16 are arranged in an inclined and equidistant manner, and the distance of each hollow groove 16 along the length direction of the body 1 is less than the interval distance between two adjacent hollow grooves 16. Although such a structural setting makes the body have a segmented structural feature, due to the setting of the carrier film layer 2, there will be no falling-off phenomenon. It only needs to be thermally bonded to the substrate during use, and the corresponding carrier film layer 2 can be torn off. The other structures corresponding to the reflective thermal sticker are consistent with the description in the first embodiment and will not be elaborated here.

[0027] During use, only the release paper layer 3 of this reflective thermal sticker needs to be torn off first, and after heating, the side of the hot melt adhesive layer is thermally bonded to the surfaces of carriers such as fabrics, police uniforms, and reflective rods, and then the carrier film layer 3 therein can be torn off.

[0028] The specific embodiments described herein are only illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0029] Although terms such as the body 1, the hot melt adhesive layer 11, the reflective layer 12, the energy storage layer 13, the fluorescent layer 14, the adhesive layer 15, the hollow groove 16, the carrier film layer 2, and the release paper layer 3 are used more in this article, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
