[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] Reference below Figure 1 The stain-resistant color-changing car cover 100 and the vehicle according to the embodiment of the present invention are described.

[0024] The stain-resistant and color-changing car cover 100 according to the present application includes: a PET protective layer 1, a stain-resistant and self-repairing varnish layer 2, a TPU base film layer 3, a color-changing layer 4, a pressure-sensitive adhesive layer 5 and a release protective film layer 6. The PET protective layer 1, the stain-resistant and self-repairing varnish layer 2, the TPU base film layer 3, the color-changing layer 4, the pressure-sensitive adhesive layer 5 and the release protective film layer 6 are stacked in sequence.

[0025] Among them, the PET (polyethylene) protective layer 1 is not easy to move or fall off during transportation, which can improve the product quality of the stain-resistant color-changing car cover 100. And the PET protective layer 1 is easy to remove after the stain-resistant color-changing car cover 100 is attached, which is convenient for maintenance and cleaning. The stain-resistant self-repairing varnish layer 2 does not affect the self-repairing performance after film formation, and is hydrophobic and has a high rolling angle, thereby improving the stain resistance and self-repairing performance of the stain-resistant color-changing car cover 100. The TPU (thermoplastic polyurethane rubber) base film layer 3 can make the stain-resistant color-changing car cover 100 have scratch self-repairing function, heat insulation, and explosion-proof function, thereby improving the safety and reliability of the whole vehicle. The color-changing layer 4 can be colored on different base colors, which can present brighter and more vivid colors. At the same time, the color-changing layer 4 has a certain transmittance. After the stain-resistant color-changing car cover 100 is attached to the vehicle body, it can be colored on different colors of the vehicle body, thereby improving the personalized performance of the stain-resistant color-changing car cover 100. The pressure-sensitive adhesive layer 5 has good initial adhesion and retention, and after the pressure-sensitive adhesive layer 5 is cured, the adhesive film is flexible, transparent, wear-resistant, weather-resistant, non-toxic, and non-polluting, thereby improving the quality and environmental friendliness of the stain-resistant color-changing car cover 100. In addition, after the pressure-sensitive adhesive layer 5 is pasted, there is no residual adhesive when it is torn off, and it is also convenient for maintenance and cleaning, thereby reducing the maintenance cost of the stain-resistant color-changing car cover 100. When using the stain-resistant color-changing car cover 100, peel off the release protective film layer 6, stick one side of the pressure-sensitive adhesive layer 5 on the car body, and then peel off the PET protective layer 1 on the other side to complete the pasting of the stain-resistant color-changing car cover 100. In addition, after the stain-resistant color-changing car cover 100 is pasted to car bodies of different colors, the stain-resistant color-changing car cover 100 can present different colors, and the effect of one film with multiple colors can be achieved.

[0026] In summary, by stacking the PET protective layer 1, the stain-resistant self-repairing varnish layer 2, the TPU base film layer 3, the color-changing layer 4, the pressure-sensitive adhesive layer 5 and the release protective film layer 6 in sequence, the stain-resistant color-changing car cover 100 can be made to have the effects of stain resistance, graffiti resistance, self-repairing, color change, heat insulation, explosion-proof, etc., thereby improving the personalization and stain resistance of the stain-resistant color-changing car cover 100, and the PET protective layer 1 and the pressure-sensitive adhesive can be torn off after bonding without residual glue, which is convenient for maintenance and cleaning, thereby reducing the maintenance cost of the stain-resistant color-changing car cover 100.

[0027] According to the stain-resistant color-changing car cover 100 of the embodiment of the utility model, by stacking the PET protective layer 1, the stain-resistant self-repairing varnish layer 2, the TPU base film layer 3, the color-changing layer 4, the pressure-sensitive adhesive layer 5 and the release protective film layer 6 in sequence, the stain-resistant color-changing car cover 100 can have the effects of stain resistance, graffiti resistance, self-repairing, color change, heat insulation, explosion-proof, etc., thereby improving the personalization and stain resistance of the stain-resistant color-changing car cover 100, and the PET protective layer 1 and the pressure-sensitive adhesive layer 5 can be torn off after bonding without residual glue, which is convenient for maintenance and cleaning, thereby reducing the maintenance cost of the stain-resistant color-changing car cover 100.

[0028] According to some embodiments of the present invention, the water contact angle of the stain-resistant self-repairing varnish layer 2 is greater than 105°, and the oil contact angle of the stain-resistant self-repairing varnish layer 2 is greater than 105°.

[0029] Among them, the water contact angle of the stain-resistant self-repairing varnish layer 2 is greater than 105°, which can improve the hydrophobicity of the stain-resistant color-changing car cover 100, and the oil contact angle of the stain-resistant self-repairing varnish layer 2 is greater than 105°, which can improve the oleophobicity of the stain-resistant color-changing car cover 100. By improving the hydrophobicity and oleophobicity of the stain-resistant color-changing car cover 100, the adsorption force of dirt molecules on the stain-resistant color-changing car cover 100 can be reduced, thereby improving the stain resistance of the stain-resistant color-changing car cover 100.

[0030] According to some embodiments of the present invention, the anti-fouling self-repairing varnish layer 2 can be constructed as a thermosetting polyurethane resin and a modified resin layer thereof.

[0031] Among them, the thermosetting polyurethane resin has better moisture resistance, alkali resistance and acid resistance than the polyurethane resin, thereby improving the moisture resistance, alkali resistance and acid resistance of the anti-fouling self-repairing varnish layer 2. And compared with the polyurethane resin, the polyurethane resin modified resin layer has higher wear resistance, impact resistance and chemical resistance, thereby improving the wear resistance, impact resistance and chemical resistance of the anti-fouling self-repairing varnish layer 2, thereby improving the wear resistance, impact resistance and chemical resistance of the anti-fouling color-changing car cover 100, and the polyurethane resin modified resin layer can also reduce the manufacturing cost of the anti-fouling color-changing car cover 100 by reducing the use of raw materials and optimizing the process flow on the premise of improving the original performance of polyurethane.

[0032] Furthermore, the polyurethane resin modified resin layer can also include fluorine, silicone modified hydrophobic coating and other substances, so that the elongation at break of the stain-resistant self-repairing varnish layer 2 can be greater than 100% (elongation at break is an indicator of the softness and elasticity of the fiber, and the greater the elongation at break, the better its softness and elasticity), thereby improving the softness and elasticity of the stain-resistant self-repairing varnish layer 2, so that the stain-resistant self-repairing varnish layer 2 does not affect the self-repairing performance after film formation, and is hydrophobic and has a high rolling angle, thereby improving the stain resistance of the stain-resistant self-repairing varnish layer 2.

[0033] According to some embodiments of the present invention, the elongation at break of the anti-fouling self-repairing varnish layer 2 may be greater than 100%.

[0034] Among them, the elongation at break is an indicator of the softness and elasticity of the fiber. The larger the elongation at break, the better the softness and elasticity. The elongation at break of the stain-resistant self-repairing varnish layer 2 is greater than 100%, which can improve the softness and elasticity of the stain-resistant self-repairing varnish layer 2, so that the stain-resistant self-repairing varnish layer 2 does not affect the self-repairing performance after film formation, and is hydrophobic and has a high rolling angle, thereby improving the stain resistance of the stain-resistant self-repairing varnish layer 2.

[0035] According to some embodiments of the present invention, the color-changing layer 4 may have physical nano-optical pearlescent luster, and the transmittance of the color-changing layer 4 is 85%.

[0036] Among them, the color-changing layer 4 can have physical nanometer light-changing pearlescent light, and the particle size of the light-changing pearlescent light can be 20nm-70nm. For example, the particle size of the light-changing pearlescent light can be 20nm, 21nm, 21.1nm, 30nm, 50nm, 70nm and other values, but the utility model is not limited to this. The particle size of the light-changing pearlescent light can also be other values ​​between 20nm-70nm, as long as the particle size of the light-changing pearlescent light is 20nm-70nm. And the color-changing layer 4 is a stack of sheet-like light-changing pearlescent light. The light-changing pearlescent light will produce obvious color-changing effects under different lighting conditions with the change of observation angle and the refraction and interference of light, so that the light-changing pearlescent light will show different colors and gloss effects at different angles and lighting conditions, thereby achieving the color-changing effect of the stain-resistant color-changing car cover 100. And the transmittance of the color-changing layer 4 can be 85%, so that the color-changing layer 4 can be colored on different base color car bodies, which can present brighter and more vivid colors. After the stain-resistant color-changing car cover 100 is attached to car bodies of different colors, the stain-resistant color-changing car cover 100 can present different colors, and the effect of one film with multiple colors can be achieved, thereby enhancing the personalized performance of the stain-resistant color-changing car cover 100.

[0037] According to some embodiments of the present invention, the PET protective layer 1 is constructed as a non-silicone release film, and the release force of the PET protective layer 1 is 300-900g, and the surface dyne value of the PET protective layer 1 is 20-26.

[0038] Among them, the PET protective layer 1 can be constructed as a non-silicone release film, which has the characteristics of uniform and stable release force, uniform thickness, strong temperature resistance and weather resistance, good tensile strength, good thermal stability, etc. Different release weights have different effects on the coating effect and peeling strength. The release force of the PET protective layer 1 is 300-900g, which can make the PET protective layer 1 have a strong peeling force, thereby effectively preventing the PET protective layer 1 from moving or falling off during transportation, and the PET protective layer 1 is easy to remove after the bonding is completed, which is convenient for maintenance and cleaning.

[0039] The dyne value can be used to measure the bonding performance of the material surface, that is, the bonding ability of the material surface with another material. Generally, the larger the dyne value, the better the bonding performance of the material surface with another material. The surface dyne value of the PET protective layer 1 is 20-26, which can make the PET protective layer 1 have better bonding performance with its adjacent layer materials, thereby further effectively preventing the PET protective layer 1 from moving or falling off.

[0040] According to some embodiments of the present invention, the tensile strength of the TPU base film layer 3 is greater than 30 MPa, the elongation at break is greater than 300%, and the UV blocking is greater than 90%.

[0041] Among them, the TPU base film layer 3 includes but is not limited to polycaprolactone, polycarbonate, polyester and other materials, has the advantages of hydrolysis resistance and weather resistance, and the tensile strength of the TPU base film layer 3 after film formation is greater than 30Mpa, which can improve the toughness and strong resistance of the TPU base film layer 3, the elongation at break of the TPU base film layer 3 is greater than 300%, which can improve the softness and elasticity of the TPU base film layer 3, and the UV blocking of the TPU base film layer 3 is greater than 90%, which can improve the heat insulation effect of the TPU base film layer 3, thereby making the stain-resistant and color-changing car cover 100 have scratch self-repairing function, heat insulation, and explosion-proof function, thereby improving the safety and reliability of the entire vehicle.

[0042] According to some embodiments of the present invention, the pressure-sensitive adhesive layer 5 can be constructed as acrylic / polyurethane pressure-sensitive adhesive and its modified body. The modified pressure-sensitive adhesive layer 5 has a high peeling force, so that the adhesive film has strong cohesive force, so that the pressure-sensitive adhesive layer 5 has good initial adhesion and retention force, and the pressure-sensitive adhesive layer 5 is flexible, transparent, wear-resistant, weather-resistant, non-toxic, and pollution-free after curing, thereby improving the quality and environmental protection of the stain-resistant color-changing car cover 100. In addition, the pressure-sensitive adhesive layer 5 can be torn off after bonding without residual adhesive, and it is also convenient for maintenance and cleaning, thereby reducing the maintenance cost of the stain-resistant color-changing car cover 100.

[0043] It can be explained that when using the stain-resistant color-changing car cover 100, peel off the release protective film layer 6, stick one side of the pressure-sensitive adhesive layer 5 on the car body, and then peel off the PET protective layer 1 on the other side.
