Embodiment 1
[0092] Combine below figure 1 To illustrate this embodiment, a composite anti-fouling, anti-ultraviolet, heat-insulating and heat-insulating polyester film includes a finishing layer 1, a metal coating layer 2, a heat-insulating layer and a core layer 4. The thermal insulation layer can block more than 99% of ultraviolet rays and more than 85% of infrared rays, and has excellent thermal insulation performance. The heat insulation layer includes an upper heat insulation layer 3 and a lower heat insulation layer 4, and the total thickness of the upper heat insulation layer 3 and the lower heat insulation layer 4 is 8 μm. The decoration layer 1, the metal coating layer 2, the upper heat insulation layer 3, the core layer 4 and the lower heat insulation layer 5 are arranged in sequence from top to bottom. The overall thickness of the polyester film was 30 μm.

Embodiment 2
[0102] A composite anti-fouling, anti-ultraviolet, heat-insulating and heat-insulating polyester film is similar to Example 1, except that the heat-insulation layer is made of the following raw materials in weight ratio: optical-grade PET raw material particles: ultraviolet blocking masterbatch: Infrared blocking masterbatch = 97%: 1.2%: 1.8%.
Embodiment 3
[0104] A composite anti-fouling, anti-ultraviolet, heat-insulating and heat-insulating polyester film, similar to Example 1, the difference is that the metal layer is nano-scale metal copper, the modification layer is perfluorooctyltrimethoxysilane, and the heat-insulation layer The barrier masterbatch is made of optical grade PET raw material particles: UV barrier masterbatch: infrared barrier masterbatch = 97%: 1.5%: 1.5%.
