[0023] The effect achieved by the entire embodiment 1 is that the substrate layer 101 is made of polyester film, which has good weather resistance, can resist ultraviolet rays, oxidation and chemical corrosion, and has good strength and toughness; the metallized layer 102 is made of aluminum film material, which has high reflectivity, can effectively reflect light, improve the reflective performance of the reflective film, and is relatively light; the heat insulation layer 103 is made of zinc oxide material, which has good heat insulation performance, can effectively block heat conduction, reduce the transfer of heat inside the reflective film, and has high thermal resistance; the insulating layer 104 is made of polypropylene film, which has good weather resistance The reflective film 105 has good weather resistance and heat resistance, and can resist the influence of ultraviolet rays, high temperature and other factors on the reflective film, and prolongs its service life. The anti-reflection film 105 adopts polyvinyl chloride material with good optical transparency, which can reduce the reflection and scattering of light, improve the transmittance and brightness of the reflective film, enhance the reflective effect, and make the reflective film body 1 have higher heat insulation performance. At the same time, after the reflective film body 1 is pasted with the mounting plate 3, the heat exchange between the reflective film body 1 and the surrounding environment can be effectively increased through the setting of the heat dissipation fins 4, and the heat conduction and dissipation can be accelerated, thereby reducing the surface temperature of the reflective film body 1 and further improving the heat insulation performance.
