Abstract

The invention discloses a blue-light-proof and ultraviolet-proof polyester film as well as a preparation method and application thereof, and belongs to the technical field of composite films. The polyester film specifically comprises a polyester film layer A, a polyester film layer B and a polyester film layer C which are sequentially stacked, wherein each of the polyester film layer A and the polyester film layer C comprises the following raw materials in parts by weight: 30-50 parts of polyester chips and 50-70 parts of an anti-blocking agent; and the polyester film layer B comprises the following raw materials in parts by weight: 70-80 parts of polyester chips, 10-15 parts of an ultraviolet light absorber, 10-15 parts of an anti-blue light additive and 5-10 parts of a blue light absorber. According to the polyester film disclosed by the invention, the blue-light-proof additive and the ultraviolet-proof additive are added into the middle layer B, so that the film achieves ultraviolet-proof and blue-light-proof effects, and meanwhile, the film has anti-sticking performance and high light transmittance; and in addition, the blue-light-proof and ultraviolet-proof polyester film can emit blue light in the sun and has a dazzle light effect.

Description

technical field [0001] The invention relates to the technical field of composite films, and more specifically relates to an anti-blue light and anti-ultraviolet polyester film and its preparation method and application. Background technique [0002] Long-term exposure to blue light can easily cause eye damage, especially macular degeneration. Specifically, blue light can penetrate the lens and reach the retina, causing optical damage to it, accelerating the oxidation of cells in the macular area, generating a large number of free radicals, leading to cataracts and macular degeneration; in addition, blue light can directly reach the retina, causing myopia, and it can also stimulate Brown pigment in the human body is an important cause of macula and freckles on the skin. At the same time, blue light can also cause blurred vision, lead to visual fatigue, and make people suffer from VDT syndrome and other diseases. [0003] In addition, ultraviolet radiation can cause damage to...
