Description

Technical Field

[0001] This utility model relates to the field of reflective film technology, and in particular to a reflective film with heat insulation function. Background Technology

[0002] With the development of modern society, reflective film has been widely used in many fields such as construction, automobiles, and transportation. In the construction field, reflective film can be used on window glass to regulate indoor light and temperature. In the automotive field, reflective film can be used on vehicle windows and bodies to enhance vehicle visibility at night or in low-visibility environments, while also providing some heat insulation for the vehicle interior. In the transportation field, reflective film is widely used in road markings, warning signs, etc., to ensure traffic safety.

[0003] Most existing reflective films focus only on improving reflective performance, such as using glass bead technology and microprism technology to enhance retroreflection, but neglect the optimization of heat insulation function. In hot weather, a large amount of infrared radiation from the sun passes through the reflective film into the indoor or vehicle interior, causing the temperature to rise sharply, increasing the energy consumption of air conditioning and other cooling equipment, and reducing people's comfort. Furthermore, the structure and performance of the reflective film itself are easily affected by long-term exposure to high temperatures, resulting in problems such as aging, fading, and delamination, thus shortening the service life of the reflective film. Therefore, we propose a reflective film with heat insulation function. Utility Model Content

[0004] The purpose of this invention is to provide a reflective film with heat insulation function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reflective film with heat insulation function, comprising a reflective film body and an auxiliary mechanism disposed on its outer side, the reflective film body comprising a wear-resistant protective layer, a first heat insulation layer fixedly installed on the inner side of the wear-resistant protective layer, an ultraviolet blocking layer fixedly installed on the inner side of the first heat insulation layer, a reflective layer fixedly installed on the inner side of the ultraviolet blocking layer, a second heat insulation layer fixedly installed on the inner side of the reflective layer, and an adhesive layer fixedly installed on the inner side of the second heat insulation layer.

[0006] As a preferred embodiment, the wear-resistant protective layer is made of a polymer material containing nano-sized wear-resistant particles, the first heat insulation layer is composed of alternating layers of nano-aerogel and heat-insulating fiber fabric, and the ultraviolet blocking layer is made of a transparent resin material containing ultraviolet absorbers.

[0008] As a preferred embodiment, the auxiliary mechanism includes a protective film, a bottom adhesive paper, and an auxiliary positioning film. The protective film is adhered to the surface of the wear-resistant protective layer, and the surface of the protective film is provided with grid lines. A tear-off handle is fixedly installed on one side of the protective film.

[0009] As a preferred embodiment, the bottom adhesive paper is adhered to the bottom of the adhesive layer.

[0010] As a preferred embodiment, an easy-tear connecting strip is fixedly installed on the outer wall of the auxiliary positioning film, and the side of the easy-tear connecting strip away from the auxiliary positioning film is installed on the side of the reflective film body. A backing paper is adhered to the bottom of the auxiliary positioning film.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the synergistic effect of the first and second heat insulation layers, heat from solar radiation is effectively blocked, significantly reducing the inner temperature of the object being bonded, reducing energy consumption of cooling equipment, and improving comfort. The reflective layer uses a microprism structure and high-refractive-index optical resin material to ensure high reflectivity and good light transmittance. The wear-resistant protective layer can effectively resist scratches and abrasions and protect the internal structure. In addition, the ultraviolet blocking layer can prevent aging and damage to the internal structure and extend the service life of the reflective film.

The auxiliary positioning film can be used to position the reflective film before it is pasted, and the size of the reflective film to be pasted is determined by the grid lines. After the reflective film is pasted, the auxiliary positioning film can be quickly removed from the reflective film with the easy-tear connecting strip without affecting the use of the reflective film.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 A reflective film with heat insulation function includes a reflective film body 1 and an auxiliary mechanism 2 disposed on its outer side. The reflective film body 1 includes a wear-resistant protective layer 101. A first heat insulation layer 102 is fixedly installed on the inner side of the wear-resistant protective layer 101. An ultraviolet blocking layer 103 is fixedly installed on the inner side of the first heat insulation layer 102. A reflective layer 104 is fixedly installed on the inner side of the ultraviolet blocking layer 103. A second heat insulation layer 105 is fixedly installed on the inner side of the reflective layer 104. An adhesive layer 106 is fixedly installed on the inner side of the second heat insulation layer 105.

[0022] The wear-resistant protective layer 101 is made of a polymer material containing nano-sized wear-resistant particles, the first heat insulation layer 102 is composed of alternating layers of nano-aerogel and heat insulation fiber fabric, and the ultraviolet blocking layer 103 is made of a transparent resin material containing ultraviolet absorbers.

[0023] The wear-resistant protective layer 101 is made of a specially formulated polymer material containing nano-sized wear-resistant particles, such as nano-silica and nano-alumina, which are uniformly dispersed in the polymer matrix through a special process. This structure gives the wear-resistant protective layer 101 excellent wear resistance, effectively resisting scratches and abrasions during daily use and protecting the internal structure from damage. It also has good light transmittance, without significantly affecting the optical performance of the reflective film. The nano-aerogel has extremely low thermal conductivity and is one of the best-performing solid materials known for its heat insulation properties, effectively preventing heat conduction. The heat-insulating fiber fabric layer is made of high-temperature resistant, low-thermal-conductivity fibers, such as ceramic fibers and basalt fibers. This not only provides excellent heat insulation but also enhances the mechanical strength of the first heat-insulating layer 102, preventing damage to the nano-aerogel layer during use. The transparent resin material containing ultraviolet absorbers effectively absorbs ultraviolet rays from solar radiation, preventing aging and damage to the reflective layer 104 and other internal structures, thus extending the service life of the reflective film.

[0024] The reflective layer 104 is made of a high-refractive-index optical resin material, the second heat insulation layer 105 is formed by vacuuming between two high-barrier films, and the adhesive layer 106 is composed of a pressure-sensitive adhesive material with good adhesion properties.

[0025] The reflective layer 104 efficiently reflects light back, improving the retroreflective performance of the reflective film. Simultaneously, transparent optical adhesive with certain heat-insulating properties is filled in the gaps, further enhancing the heat insulation effect of the reflective layer 104. The vacuum layer significantly reduces heat transfer through conduction and convection, effectively blocking external heat from entering. The adhesive layer 106 firmly adheres the reflective film to the surface of the target object. Furthermore, the pressure-sensitive adhesive layer, with its specially optimized formula, possesses certain weather resistance and temperature resistance, maintaining stable adhesion under various environmental conditions.

[0026] Specifically, through the synergistic effect of the first heat insulation layer 102 and the second heat insulation layer 105, heat from solar radiation is effectively blocked, significantly reducing the inner temperature of the adhered object, reducing energy consumption of the cooling equipment, and improving comfort. The reflective layer 104 uses a microprism structure and high-refractive-index optical resin material to ensure high reflectivity and good light transmittance. The wear-resistant protective layer 101 can effectively resist scratches and wear, protecting the internal structure. In addition, the ultraviolet blocking layer 103 can prevent aging and damage to the internal structure and extend the service life of the reflective film. The adhesive layer 106 uses a specially formulated and optimized pressure-sensitive adhesive with good adhesion, weather resistance, and temperature resistance, which can firmly adhere the reflective film under different environmental conditions.

[0027] Please see the appendix Figure 1 - Appendix Figure 4The auxiliary mechanism 2 includes a protective film 201, a bottom adhesive paper 204, and an auxiliary positioning film 205. The protective film 201 is pasted on the surface of the wear-resistant protective layer 101. The surface of the protective film 201 is provided with grid lines 203. A tear-off handle 202 is fixedly installed on one side of the protective film 201.

[0028] The grid lines 203 on the protective film 201 are precise graduation lines, which users can cut according to their needs. The tear handle 202 makes it easy to tear off the protective film 201.

[0029] The bottom adhesive paper 204 is pasted on the bottom of the adhesive layer 106.

[0030] After the adhesive layer 106 is pasted on the bottom adhesive paper 204, it can be easily peeled off without leaving any residue and without affecting the adhesive performance of the adhesive layer 106.

[0031] An easy-tear connecting strip 207 is fixedly installed on the outer wall of the auxiliary positioning film 205. The side of the easy-tear connecting strip 207 away from the auxiliary positioning film 205 is installed on the side of the reflective film body 1. A backing paper 206 is adhered to the bottom of the auxiliary positioning film 205.

[0032] The easy-tear connecting strip 207 allows the auxiliary positioning film 205 to be easily separated from the reflective film body 1 without affecting the use of the reflective film.

[0033] Specifically, the protective film 201 and the bottom adhesive paper 204 protect the reflective film. The auxiliary positioning film 205 can be used to position the reflective film before it is pasted, and the grid lines 203 determine the size of the reflective film to be pasted. After the reflective film is pasted, the auxiliary positioning film 205 can be quickly removed from the reflective film using the easy-tear connecting strip 207 without affecting the use of the reflective film.

[0034] Working principle of this utility model: This utility model is a reflective film with heat insulation function. When using the reflective film, firstly, cut the reflective film according to the grid lines 203 to the required size. Then, peel off the backing paper 206 on the back of the auxiliary positioning film 205. According to the required position of the reflective film, stick the auxiliary positioning film 205 in the corresponding position. Then, peel off the bottom adhesive paper 204 on the back of the reflective film and stick the reflective film to the target position through the adhesive layer 106. Finally, hold the tear handle 202 and peel off the protective film 201 for use. In the first heat insulation layer 102, the nano-aerogel has extremely low heat... The conductive properties effectively prevent heat conduction. The heat-insulating fiber fabric not only provides insulation but also enhances mechanical strength, preventing damage to the nano-aerogel layer. The vacuum environment of the second insulation layer 105 greatly reduces heat conduction and convection. The reflective layer 104 is made of high-refractive-index optical resin material, and its special surface optical treatment allows light to be reflected multiple times, efficiently reflecting back and improving retroreflective performance. The filled transparent optical adhesive also plays a certain role in heat insulation, reducing the heat generated by the reflective layer 104 due to light absorption. The nano-scale wear-resistant particles of the wear-resistant protective layer 101 are uniformly dispersed in the polymer matrix, enhancing surface hardness, resisting scratches and wear, and not affecting optical performance. The ultraviolet absorber in the ultraviolet blocking layer 103 absorbs ultraviolet rays from solar radiation, preventing them from damaging the internal structure.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
