Technical Field
[0001] The utility model relates to the technical field of reflective films, in particular to a high-temperature resistant reflective film. Background Art
[0002] A reflective film is a retroreflective material that has been made into a film and can be directly applied. It is made by using technologies such as glass bead technology, microprism technology, synthetic resin technology, film technology, coating technology, and microreplication technology. It usually comes in white, yellow, red, green, blue, brown, orange, fluorescent yellow, fluorescent orange, fluorescent yellow-green, and abroad there are also fluorescent red and fluorescent pink. The application of reflective films is very extensive, widely used in the production of traffic signs and markings, which can improve night driving safety. By utilizing the retroreflective characteristics, the reflective film enables drivers to detect the vehicle or road signs ahead earlier at night, so as to take safety measures in advance and avoid traffic accidents. It is also used for body contour identification to improve the recognition of vehicles. The application of reflective films is not limited to improving traffic safety, but also includes improving the safety and visibility of people and items in specific environments. However, the surface of the existing reflective films is exposed to wind, sun and rain, which makes the color inside the reflective film fade, affecting the use effect, and it is not waterproof. Water easily penetrates into the inside of the reflective film, making the color of the reflective film fade and affecting the use effect.
[0003] As the publication number: CN214656563U, a reflective film includes a reflective film layer group and an active light-emitting layer group.
