[0015] Reference numerals: Substrate layer-1, Adhesive layer-2, Backing protective layer-3, Anti-blue light layer-4, UV reflective layer-5, Self-healing layer-6, Wear-resistant coating-7. Detailed Implementation

[0016] like Figure 1 As shown, this utility model proposes: a UV protective film for automotive glass, comprising a substrate layer 1;

[0017] Among them, substrate layer 1 is a PET film layer, etc. (PET film has high transparency, good mechanical strength, good chemical resistance, etc.);

[0018] Adhesive layer 2 and backing protective layer 3 are sequentially bonded and fixed to one end of substrate layer 1;

[0019] Among them, the base layer 2 is an acrylic pressure-sensitive adhesive layer, etc. (acrylic pressure-sensitive adhesive has excellent transparency, initial tack and holding power).

[0020] The backing protective layer 3 is a PET release film (PET release film is a thin film material with PET as the base material and a layer of release agent coated on its surface after special treatment). When using it, simply peel off the backing protective layer 3 and then stick the base adhesive layer 2 onto the car glass to stabilize it.

[0021] And the blue light blocking layer 4, the UV reflective layer 5, and the wear-resistant coating 7 are sequentially bonded and fixed to the other end of the substrate layer 1;

[0022] The blue light blocking layer 4 is designed to protect the eyes and reduce the damage from blue light emitted by the light source during long-term driving.

[0023] The UV reflection layer 5 is a UV reflection heat insulation layer, which provides the function of reflecting infrared rays (heat) and blocking ultraviolet rays, and improves protection and comfort;

[0024] The UV reflection heat insulation layer is a metal plating layer;

[0025] The metal plating layer is a nickel plating layer or the like (the nickel plating layer is deposited on the anti-blue light layer 4 by magnetron sputtering or the like, has good light transmittance, and has good heat insulation effect);

[0026] The wear-resistant coating 7 is a silicone resin coating or the like (the silicone resin coating provides excellent hardness, weather resistance, and transparency to protect the underlying material layers);

[0027] It also includes a self-repairing layer 6, which is attached and fixed between the UV reflection layer 5 and the wear-resistant coating 7, and can restore itself under certain conditions when the wear-resistant coating 7 is slightly scratched, thereby prolonging the service life and maintaining the appearance;

[0028] The self-repairing layer 6 is a TPU self-repairing film layer or the like, and the TPU self-repairing film only needs to be heated to a certain temperature (such as natural heating under sunlight) to increase the intermolecular force, promote the closure of scratches, and make the surface smoother, more beautiful, and more protective;

[0029] Self-repairing mechanism of the TPU self-repairing film layer: the self-repairing material realizes self-repairing through a specific mechanism. For a heat-sensitive self-repairing material, the molecules in the material will rearrange and close the cracks when heated to a certain temperature (for example, sunlight);

[0030] Actual application of the TPU self-repairing film layer: when a slight scratch occurs, the scratch damage does not penetrate below the self-repairing layer 6 (if the damage penetrates below the self-repairing layer 6, the flatness after repair may not be high), then under appropriate conditions (such as temperature rise), the self-repairing layer 6 will start to work and gradually fill in these small gaps or cracks. During this process, although the wear-resistant coating 7 on the surface seems to be the entire film that is self-repairing, in fact, the self-repairing layer 6 plays a major role, making the wear-resistant layer above appear smoother, giving a feeling of overall recovery.

[0031] The basic principle and main features of the present application and the advantages of the present application are shown and described above, for those skilled in the art, obviously the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the present application.
