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%.

Abstract

The invention provides a composite anti-fouling anti-ultraviolet heat insulation polyester film and a preparation method thereof, the composite anti-fouling anti-ultraviolet heat insulation polyester film comprises a modification layer, a metal coating layer, a heat insulation layer and a core layer, the heat insulation layer comprises an upper heat insulation layer and a lower heat insulation layer, and the modification layer, the metal coating layer, the upper heat insulation layer, the core layer and the lower heat insulation layer are sequentially arranged from top to bottom. Through function optimization, on the basis that the thin film has heat insulation and heat preservation, the antifouling property is compounded, and the thin film not only has high super-hydrophobic property, but also has excellent super-oleophobic property.

Description

technical field [0001] The invention belongs to the technical field of polyester films, and in particular relates to a composite anti-fouling, anti-ultraviolet, heat-insulating and heat-insulating polyester film and a preparation method thereof. Background technique [0002] Polyester film (PET) is a film material made of polyethylene terephthalate as a raw material, which is made into a thick sheet by extrusion and then biaxially stretched. Polyester film is a kind of polymer plastic film, which is more and more favored by consumers because of its excellent comprehensive performance. Since my country's production volume and technical level still cannot meet the demand of the market, some still need to rely on imports. [0003] Polyester film is usually a transparent and glossy film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high temperature and low temperature resistance, and good air tightness. It...
