Description

Technical Field

[0001] This utility model relates to the field of decorative film technology, specifically a novel high-temperature resistant iridescent film. Background Technology

[0002] Rainbow film is a plastic composite film with unique optical effects. It is a multi-layer film made by melting and extruding two or more resins with different refractive indices and stacking them alternately. This structure allows rainbow film to produce rich light effects and color changes when illuminated.

[0003] The existing color film has poor heat dissipation capabilities. When used in high-temperature environments, it may cause the temperature to become too high. Excessive temperature not only accelerates the aging process of the film and shortens its service life, but may also cause the film's color to change, affecting its appearance. Utility Model Content

[0004] The purpose of this invention is to provide a novel high-temperature resistant multicolor film to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel high-temperature resistant multicolor film, comprising a substrate layer, a heat dissipation layer disposed on the upper surface of the substrate layer, a protective layer disposed on the upper surface of the heat dissipation layer, a reflective layer disposed on the lower surface of the substrate layer, a thermally conductive layer disposed on the upper surface of the reflective layer, an adhesive layer fixedly bonded to the lower surface of the thermally conductive layer, a plurality of staggered longitudinal and transverse grooves being formed at the bottom of the thermally conductive layer, and a release layer disposed on the lower surface of the adhesive layer.

[0009] In a preferred embodiment of this utility model, the heat dissipation layer is a hydrogel film with a thickness of 0.1mm-0.2mm.

[0010] In a preferred embodiment of this utility model, the reflective layer is a heat-reflective coating, and the reflective layer is sprayed on the upper surface of the heat-conducting layer.

[0011] In a preferred embodiment of this utility model, the heat-conducting layer is a copper film, and the thickness of the heat-conducting layer is 0.3mm-0.5mm.

[0017] 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.

[0018] Please see Figures 1 to 3This utility model provides a technical solution: a novel high-temperature resistant iridescent film, comprising a substrate layer 3, which is formed by melt extrusion of two or more resins with different refractive indices and sequentially stacked at intervals, enabling it to produce rich light effects and color changes under light irradiation. A heat dissipation layer 2 is disposed on the upper surface of the substrate layer 3, which accelerates heat dissipation to improve the heat dissipation capacity of the iridescent film. A reflective layer 4 reflects sunlight, reducing the heat accumulation of solar radiation energy and lowering the temperature of the substrate layer 3. Simultaneously, a heat-conducting layer 5 conducts heat from the substrate layer 3, preventing heat accumulation on the substrate layer 3, allowing the iridescent film to maintain a lower temperature even in high-temperature environments, thereby improving its high-temperature resistance. A protective layer 1 is disposed on the upper surface of the heat dissipation layer 2. The protective layer 1 protects the heat dissipation layer 2 and the substrate layer 3, preventing them from being scratched. A reflective layer 4 is provided on the lower surface of the substrate layer 3, and a heat-conducting layer 5 is provided on the upper surface of the reflective layer 4. An adhesive layer 6 is fixedly bonded to the lower surface of the heat-conducting layer 5. The adhesive layer 6 is a polyacrylate pressure-sensitive adhesive, which facilitates the application of the color-changing film. The bottom of the heat-conducting layer 5 has multiple staggered longitudinal grooves 9 and transverse grooves 10, which allow air to flow through one side of the heat-conducting layer 5 and carry away its heat. A release layer 7 is provided on the lower surface of the adhesive layer 6. The release layer 7 is a PE release film, which prevents the adhesive layer 6 from sticking before the color-changing film is used, and ensures that the release layer 7 and the adhesive layer 6 can be easily separated when the color-changing film is applied.

[0019] The protective layer 1 has multiple evenly distributed through holes 8, which facilitate the heat dissipation layer 2 to come into contact with air.

[0020] The diameter of the through hole 8 is 1 mm, and the width of the longitudinal groove 9 and the transverse groove 10 is 2 mm.

[0021] Among them, the protective layer 1 is a PET protective film. The PET protective film has high transparency, which can clearly show the color of the substrate layer 3. It also has good wear resistance and weather resistance, and can maintain good performance under different environmental conditions, thus playing a good protective role. The thickness of the protective layer 1 is 0.025mm-0.05mm.

[0022] Among them, heat dissipation layer 2 is a hydrogel film. When the temperature is high, the hydrogel film carries away heat through water evaporation, improving the heat dissipation capacity of the rainbow film. When the temperature drops, the hydrogel film can automatically absorb moisture from the air and achieve recycling. In addition, the hydrogel film has good thermal conductivity, which can conduct the heat of the substrate layer 3 to the outside air, further reducing the temperature of the rainbow film. At the same time, the hydrogel film is a transparent material and will not block the color of the substrate layer 3. The thickness of heat dissipation layer 2 is 0.1mm-0.2mm.

[0023] Among them, the reflective layer 4 is a heat-reflective coating, which can reflect sunlight and reduce the heat accumulation of solar radiation energy. The reflective layer 4 is sprayed on the upper surface of the heat-conducting layer 5.

[0024] Among them, the heat-conducting layer 5 is a copper film. The copper film has good thermal conductivity and conducts heat from the substrate layer 3. It can transfer some of the heat to the object being pasted, and at the same time, it can dissipate some of the heat into the air through the longitudinal groove 9 and the transverse groove 10. The thickness of the heat-conducting layer 5 is 0.3mm-0.5mm.

[0025] Specifically, during use, the release layer 7 is peeled off, and the colorful film is pasted to the desired location through the adhesive layer 6. When exposed to sunlight, the reflective layer 4 reflects sunlight, reducing the heat accumulation of solar radiation energy and lowering the temperature of the substrate layer 3. When the temperature is high, the heat dissipation layer 2 removes heat through moisture evaporation. When the temperature drops, the heat dissipation layer 2 can automatically absorb moisture from the air for recycling. Furthermore, the heat dissipation layer 2 has good thermal conductivity, which can conduct the heat of the substrate layer 3 to the outside air. At the same time, some of the heat of the substrate layer 3 is transferred to the heat-conducting layer 5, which in turn transfers some of the heat to the object being pasted. Some of the heat is dissipated into the air through the longitudinal grooves 9 and the transverse grooves 10, thus preventing heat from accumulating on the substrate layer 3 and causing the substrate layer 3 to become too hot.
