Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of color-changing clothes, and particularly relates to a light and thin color-changing clothes. BACKGROUND

[0002] With the continuous development of economy, people's demand for car color changing is rising. In order to meet the customers' demand for car color changing, the color changing technology is also constantly updated and iterated. At present, the car color changing technology is the two technical means of paint spraying and traditional film pasting process. The film pasting process is to paste the manufactured color-changing clothes to the surface of the car to achieve color changing.

[0003] The existing color-changing clothes use TPU material as the base material layer. The TPU material layer has certain protection performance while maintaining a light and thin state. Then a color-changing layer is arranged on the upper layer of the TPU base material layer. The color-changing layer displays color outwardly. In order to improve the protection performance, a protective layer is arranged on the color-changing layer. A glue layer is arranged on the lower layer of the TPU base material layer for pasting the clothes on the outer surface of the car. For details, please refer to the authorized announcement No. CN216659193U, a light and thin durable TPU color-changing clothes. The PET anti-adhesion layer, glue layer, TPU base material layer, multi-layer effect color-changing layer, multifunctional protective layer, and release protective layer are arranged in the clothes from inside to outside.

[0004] The existing technical solution has the following disadvantages: Although the light and thin color-changing clothes disclosed in the above-mentioned existing technical solution improve the anti-ultraviolet, anti-aging, wear-resistant, and tear-resistant performance of the clothes by arranging a multifunctional protective layer, the tearable PET paper on the surface of the clothes will be torn off during use. The clothes are mainly protected by the outward protective layer to ensure the service life of the clothes. Once the protective layer is damaged or aged due to long time, the protection performance will decrease, resulting in general durability of the clothes. In addition, the existing clothes also have general flame retardant performance. Although the multifunctional protective layer disclosed in the existing technical solution is a heat-resistant protective layer or a UV protective layer and has certain flame retardant performance, the release protective layer on the upper layer and the anti-adhesion layer on the lower layer of the clothes are both tearable PET paper, which does not have flame retardant performance. Before use, the tearable PET paper on the upper and lower layers only protects the clothes itself and prevents the glue layer from being contaminated. Once the clothes come into contact with an open flame during transportation, the clothes will easily catch fire. When the clothes are pasted, the tearable PET paper on the upper and lower layers will be torn off, but the remaining material layers of the clothes, such as the glue layer and the TPU base material layer, also do not have flame retardant performance. Although the heat-resistant protective layer or the UV protective layer as the outermost layer has certain flame retardant performance, once the protective layer is damaged, the internal material layers will easily catch fire. For example, when a vehicle involved in a traffic accident collides and catches fire, the pasted clothes will easily be damaged due to the collision. At this time, if the vehicle body appears an open flame, the pasted clothes will easily catch fire. In addition, the clothes of the existing technology are torn off. SUMMARY
