However, polyvinylidene fluoride film and PET flame-retardant film are not easy to bond, and are easily separated from the base film during use. They have poor stability, which affects their service life. They are also not conducive to the stable adhesion of the antibacterial coating, which increases the difficulty of production and needs to be improved. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model;

[0015] Figure 2 yes Figure 1 Top view of the flame retardant and weather resistant film layer. DETAILED DESCRIPTION

[0016] Combine the following Figure 1 to Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The antibacterial flame retardant and weather-resistant aviation decorative composite film shown includes: a base film layer 1, a printing layer 3, a flame retardant and weather-resistant film layer 2 and an antibacterial coating 9. The printing layer 3 is arranged on the top surface of the base film layer 1. In this embodiment, the base film layer 1 adopts PVC flame retardant film, which improves the flame retardant effect and is beneficial to the printing construction of the printing layer 3.

[0018] An aluminum-plated layer 4 is provided on the bottom surface of the base film layer 1 to cover the color of the surface of the object to be decorated and ensure the decorative effect of the pattern of the printed layer 3. A pressure-sensitive adhesive layer 5 is provided on the bottom surface of the aluminum-plated layer 4 to be attached to the surface of the object to be decorated. In this embodiment, a release paper 6 is provided on the bottom surface of the pressure-sensitive adhesive layer 5 to protect the pressure-sensitive adhesive layer 5. Before construction, the release paper 6 is torn off.

[0019] A first flame retardant adhesive layer 7 is disposed on the top surface of the printed layer 3 , and the flame retardant and weather resistant film layer 2 is disposed on the first flame retardant adhesive layer 7 . The flame retardant and weather resistant film layer 2 is fixed on the top surface of the printed layer 3 by the first flame retardant adhesive layer 7 .

[0020] A second flame retardant adhesive layer 8 is arranged on the top surface of the flame retardant and weather-resistant film layer 2, and the antibacterial coating 9 is arranged on the top surface of the second flame retardant adhesive layer 8. The second flame retardant adhesive layer 8 adopts UV flame retardant adhesive, which cures quickly and has high surface hardness, which is conducive to the coating construction of the antibacterial coating 9, and has high combined stability, thereby improving the antibacterial effect.

[0021] In this embodiment, the flame retardant and weather-resistant film layer 2 is made of polyvinylidene fluoride film or PET flame retardant film, which improves the flame retardancy and weather resistance, and is resistant to high and low temperatures, and is suitable for use in the aviation field.

[0022] like Figure 2 As shown, the flame retardant and weather resistant film layer 2 is arrayed with micropores 10, and the micropores 10 are filled with flame retardant adhesive connecting the first flame retardant adhesive layer 7 and the second flame retardant adhesive layer 8. In this embodiment, the diameter of the micropores 10 is 0.1 to 0.5 mm. The small diameter of the micropores will not form pits on the flame retardant and weather resistant film layer 2, thereby ensuring the flatness of the flame retardant and weather resistant film layer 2.

[0023] The first flame retardant adhesive layer 7 and the second flame retardant adhesive layer 8 are connected by the flame retardant adhesive in the micropores 10, so as to improve the connection stability between the flame retardant and weather-resistant film layer 2 and the printed layer 3 and avoid the separation problem between the flame retardant and weather-resistant film layer 2 and the printed layer 3. The second flame retardant adhesive layer 8 also ensures the adhesion of the antibacterial coating 9, has high structural stability, avoids the detachment of the antibacterial coating, and is more durable.

[0024] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
