It is made by using glass bead technology, synthetic resin technology, film technology, coating technology, and microreplication technology. It usually has colors such as white, yellow, red, green, brown, and orange, and is widely used in various outdoor occasions, such as construction site warning signs, roadside road signs, and the surfaces of outdoor equipment. It plays a warning role at night through the reflective film, and reminds pedestrians through the reflective characteristics of the reflective film, thereby improving safety.

[0003] For example, the publication number is: CN207216064U, a reflective film, including a reflective layer, characterized in that: a plurality of equally spaced glass microbeads are arranged inside the upper end of the reflective layer, a protective film is arranged on the upper surface of the reflective layer, the protective film is made of a high-transparency PET material, a flame-retardant layer is arranged on the upper surface of the protective film, a plurality of microprisms are arranged inside the lower end of the reflective layer, the shapes of the glass microbeads and the microprisms are both triangular, and their apex angles are oppositely arranged, the glass microbeads are flush with the upper surface of the reflective layer, the microprisms are flush with the lower surface of the reflective layer, a white glue layer is arranged between the reflective layer and the adhesive layer, and a release film is arranged on the lower surface of the adhesive layer, and the release film is made of a PE material.

The nanofiber has excellent hydrophobicity and anti-fouling properties, making the surface layer more dirt-resistant. The polyether ester elastic fiber has the characteristics of high strength and good elasticity.

[0009] Preferably, in order to improve the heat insulation performance, a heat insulation film and a PE release film are arranged inside the heat insulation layer. The PE release film is arranged at the upper end of the heat insulation film. The heat insulation film is used to isolate heat from entering, and the PE release film is used to improve the corrosion resistance.

[0010] Preferably, in order to facilitate the connection between the light reflection layer and the glass microsphere layer, the waterproof and breathable layer is installed at the upper end of the light reflection layer. The light reflection layer is installed at the upper end of the adhesive layer, and the glass microsphere layer is installed at the lower end of the adhesive layer.

The adhesive layer is composed of a pressure-sensitive adhesive. Different reflective textures are arranged on the surface of the reflective sheet. The high molecular waterproof and breathable material has a unique air permeability performance, which can discharge the heat inside the fabric.

[0012] Preferably, in order to improve transparency and the ability to suppress stray light, silica is filled inside the white glue layer, and the size of the silica is greater than 10 microns.

[0013] Preferably, in order to facilitate the pasting of the reflective film, an adhesive is filled inside the adhesive layer, and a backing paper is adhesively connected to one end of the adhesive layer.

[0023] AsFigures 1-6 As shown in the figure, the present embodiment provides a reflective film with high light efficiency, which includes a surface layer 1, a heat insulation layer 2, a reflective layer 3, a white glue layer 4 and an adhesive layer 5. The surface layer 1 includes an anti-fouling layer 101 and a flame retardant layer 102. The heat insulation layer 2 is arranged at the lower end of the surface layer 1, and the reflective layer 3 is arranged at the lower end of the heat insulation layer 2. The reflective layer 3 includes a waterproof and breathable layer 301, a light reflection layer 302, a glass microsphere layer 303 and an adhesive layer 304. The white glue layer 4 is installed at the lower end of the reflective layer 3, and the adhesive layer 5 is installed at the lower end of the white glue layer 4. The white glue layer 4 is filled with silicon dioxide, and the size of the silicon dioxide is greater than 10 microns. The adhesive layer 5 is filled with an adhesive, and one end of the adhesive layer 5 is adhesively connected with a backing paper 6. When in use, first tear off the backing paper 6 and paste this structure at the corresponding position. The anti-fouling layer 101 can prevent external dust and other impurities from adhering to the surface layer 1. The flame retardant layer 102 and the heat insulation layer 2 can isolate the external high temperature and prevent the reflective film from spontaneous combustion under long-term light conditions, with high safety. In rainy weather, the waterproof and breathable layer 301 can prevent moisture from entering the reflective layer 3. The light reflection layer 302 and the glass microsphere layer 303 are used to reflect light. The silicon dioxide improves the transparency of the reflective film and the ability to suppress stray light, making the reflected light clearer and having a good warning effect.

[0024] As Figure 2 shown in the figure, the anti-fouling layer 101 is arranged at the upper end of the flame retardant layer 102. The anti-fouling layer 101 is made of a blend of nanofiber and polyether ester elastic fiber. The flame retardant layer 102 is woven from natural fiber cotton. One end of the flame retardant layer 102 is provided with a flame retardant coating 103. The heat insulation layer 2 is internally provided with a heat insulation film 201 and a PE release film 202. The PE release film 202 is arranged at the upper end of the heat insulation film 201. When in use, when used for a long time, the nanofiber has excellent anti-fouling property, preventing impurities from adhering to the surface layer 1 and making the surface layer 1 more dirt-resistant. At the same time, the polyether ester elastic fiber can improve the strength and elasticity of the anti-fouling layer 101. The heat insulation film 201 isolates the external high temperature, and the PE release film 202 can prevent the anti-fouling layer 101 from being corroded, with strong corrosion resistance.

[0025] As Figure 4 Compared with Figure 5As shown in the figure, the waterproof and breathable layer 301 is installed at the upper end of the light reflection layer 302, the light reflection layer 302 is installed at the upper end of the adhesive layer 304, and the glass microsphere layer 303 is installed at the lower end of the adhesive layer 304. The waterproof and breathable layer 301 is made of a mixture of a polymer waterproof and breathable material and polyester filaments. The light reflection layer 302 is composed of reflective sheets 305 with different reflective angles, and the reflective sheets 305 are alternately arranged in an array. The adhesive layer 304 is composed of a pressure-sensitive adhesive. When in use, first, the glass microsphere layer 303 and the light reflection layer 302 are adhered together through the adhesive layer 304. In rainy and humid weather, the outside air humidity is relatively high. The waterproof and breathable layer 301 can prevent the outside moisture from entering the inside of the light reflection layer 3, and at the same time does not affect the discharge of the internal hot air. There can be 2 to 4 kinds of reflective sheets 305 with different reflective angles, generally 3 kinds. Since the reflective angles of the reflective sheets 305 are different, the reflectivity increases accordingly.
