[0002] Cars are an indispensable means of transportation in modern life. They greatly facilitate people's travel, shorten the distance between cities, and promote social and economic development. Colorful film is a decorative film used for car covers and interiors. It can provide vehicles with a unique appearance while protecting the original paint of the vehicle from damage. It also has the characteristics of beauty, protection, easy installation, durability and environmental protection.

[0003] When the existing colorful film is used for a long time, the adhesive tape at the edge of the pressure-sensitive adhesive layer is prone to failure, causing the edge to curl up, which affects the appearance and causes the adhesive to continue to peel off. Utility Model Content

The self-cleaning layer prevents dust from accumulating and agglomerating on the surface, reducing dust adhesion. Even if stains are attached, they can be easily removed by washing with rainwater or gently wiping, which is convenient for cleaning the surface of the colorful film later.

[0008] In one embodiment, the memory substrate includes a thermotropic SMP layer with a thickness of 10-100 microns, which changes shape when subjected to thermal stimulation and maintains the new shape after cooling. When heated to a certain temperature again, it can return to its original shape to prevent continuous curling and debonding at the edges.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1-4 The present embodiment proposes a multifunctional colorful film for vehicle decoration, including a base film layer 4, a pressure-sensitive adhesive layer 3 is provided on the lower end surface of the base film layer 4, a second release layer 2 is provided on the lower end of the pressure-sensitive adhesive layer 3, a color memory layer 5 is provided on the upper end surface of the base film layer 4, an ultraviolet blocking layer 6 is provided on the upper end surface of the color memory layer 5, a self-repairing layer 7 is provided on the upper end surface of the ultraviolet blocking layer 6, a self-repairing layer 7 is provided on the upper end surface of the self-repairing layer 7, a self-cleaning layer 8 is provided on the upper end surface of the self-cleaning layer 7, the self-cleaning layer 8 prevents dust from accumulating and agglomerating on the surface, and reduces the adhesion of dust. Even if stains are attached, they can be easily removed by washing with rainwater or gently wiping, which is convenient for cleaning the surface of the colorful film later. The upper end surface of the self-cleaning layer 8 is provided with a first release layer 1.

[0028] The color memory layer 5 includes a memory base layer 501 and a plurality of through holes 502. The plurality of through holes 502 are arranged in a rectangular shape on the upper end surface of the memory base layer 501. The plurality of through holes 502 pass through the upper end surface of the memory base layer 501 to the lower end surface of the memory base layer 501. The memory base layer 501 forms a memory shape. After long-term use, the edge of the pressure-sensitive adhesive layer 3 that is prone to debonding will not curl, reducing the possibility of continuous debonding and preventing debonding and curling at the edge, which affects the appearance.

[0029] The memory base layer 501 is made of a thermo-induced SMP layer, which changes shape when subjected to thermal stimulation and maintains its new shape after cooling. When heated to a certain temperature again, it can return to its original shape to prevent the edges from continuing to curl and debond. The self-cleaning layer 8 is made of a polytetrafluoroethylene layer, and the surface has extremely low surface energy, so that water droplets form spheres on the coating surface, which are easy to roll off and take away surface stains. The self-repairing layer 7 includes a polyurethane layer with a porous structure, and the porous structure is filled with microcapsules. When cracks appear on the coating surface, the microcapsules rupture, releasing a repair agent to fill the cracks and achieve self-repair. The ultraviolet isolation layer 6 is made of a polyurethane layer. The resin itself has a certain ultraviolet protection ability. Its protection effect can be further improved by adding ultraviolet absorbers and reflectors. The base film layer 4, the color memory layer 5, the self-repairing layer 7 and the self-cleaning layer 8 are hot pressed, adhesive pressed, solvent pressed or ultrasonic pressed to make the connectivity between the layers higher.

[0030] In this embodiment, the overall thickness of the multifunctional colorful film is about 2 mm. The thickness of the thermotropic SMP layer serving as the memory base layer 501 is about 50 microns, and the thickness of the polytetrafluoroethylene layer serving as the self-cleaning layer 8 is about 15 microns. The thickness of the porous polyurethane layer serving as the self-repairing layer 7 is about 100 microns, with a porosity of about 90%, an average pore size of about 5 microns, and an average diameter of the microcapsules filled in the pores of about 2 microns. The thickness of the polyurethane layer serving as the UV-blocking layer is about 5 microns. The above-mentioned structural layers all have a high light transmittance (over 75% on average), and can display brilliant colors when combined with the color memory layer and the colored base film layer. In addition, pigments and fillers can be filled into structural layers such as the porous polyurethane layer and the UV-blocking layer to give the multifunctional colorful film a richer structural color.

[0031] The colorful film of this embodiment can be set on the car cover or interior of motor vehicles such as cars, wherein the color memory layer 5 is laminated to the car body and interior after being heated during lamination, and the memory base layer 501 forms a memory shape. After long-term use, the edge of the pressure-sensitive adhesive layer 3 that is prone to debonding will not curl, reducing the possibility of continuous debonding, and also preventing debonding and curling at the edge, which affects the appearance. The self-cleaning layer 8 prevents surface dust from accumulating and agglomerating, and reduces dust adhesion. Even if stains are attached, they can be easily removed by washing with rainwater or gently wiping, which is convenient for cleaning the surface of the colorful film later. The self-cleaning layer 8 also has anti-ultraviolet properties. When used in conjunction with the ultraviolet blocking layer 6, it can protect the base film layer 4 from damage by ultraviolet rays and increase the service life of the colorful film. The colorful film is set on the car cover or interior of motor vehicles.

[0032] Compared with the existing technology, the multifunctional colorful film of this embodiment can be set on the car cover or interior of the car, etc. It not only has rich and varied colors, which can make the car cover, interior, etc. more beautiful, but also can protect the surface of the car cover, interior, etc. and reduce the adhesion of dirt.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
