Abstract

The invention relates to the technical field of a high-molecular material, and concretely relates to a polyester film. The polyester film is prepared by 60-80 parts of a polyester material, 20-30 parts of membrane-grade master batch, 2-9 parts of polysiloxane, 4-12 parts of a solvent, 2-4 parts of tritolyl phosphate, 1-3 parts of a curing agent, 1-2 parts of nuciferine, and 2-3 parts of flufenacet. The raw materials are uniformly mixed through a feed mixer, then a mixture is subjected to fusion extrusion through an extruder, the polyester film is prepared through vertical stretching and transverse stretching, and rolling package is carried out finally. Through reasonable designing of the components and a processing technology, the product has good transmittance and has excellent ultraviolet-resistant effect, and the product quality is good.
