Abstract

The invention discloses an anti-ultraviolet PET film and a preparation method thereof. The anti-ultraviolet PET film comprises the following raw materials by weight part: PET polyester chip, vinyl organic silicon resin, conductive polymer resin, a silane coupling agent, toluene, butanone, a first ultraviolet absorbent, a second ultraviolet absorbent, an anti-scratch agent, an anti-blocking agent, an oily nano-titanium dioxide dispersion agent, a thioxanthone photoinitiator, glycerol, an antioxidant, and calcium stearate. The anti-ultraviolet PET film provided by the invention has the characteristics of good heat sealability, high heat shrinkage, easy recovery and good mechanical properties, contains ultraviolet absorbents, and can absorb ultraviolet. Also the ultraviolet absorbents are difficult to migrate, thus greatly prolonging the timeliness of the anti-ultraviolet function. The anti-ultraviolet PET film provided by the invention can be used for making anti-ultraviolet heat-insulating film products, can be used for ultraviolet protection of automobiles, constructions and the like, effectively blocks the harmful ultraviolet encountered in daily life, and avoids the damage of ultraviolet to the human body.

Description

technical field [0001] The invention relates to the technical field of film manufacture, in particular to an ultraviolet-resistant PET film and a preparation method thereof. Background technique [0002] Ultraviolet rays in sunlight are the main cause of aging of polymer materials. Polymer materials will absorb ultraviolet rays and cause self-oxidation, resulting in polymer degradation. This process is called photoredox or photoaging. Although ultraviolet light only accounts for about 5% of sunlight, its energy is very large, and its energy is enough to destroy the chemical bonds of polymers, make its molecular chains break and crosslink, resulting in malignant changes in its mechanical properties, and at the same time, its color will also change. Ultraviolet rays can be divided into short-wave regions (ie UVC: 200nm-290nm), medium-wave regions (ie UVB: 290nm-320nm) and long-wave regions (ie UVA: 320nm-400nm) according to wavelength. When sunlight passes through the atmosph...
