Abstract

The invention relates to an anti-ultraviolet, heat-insulating and radiation-proof PET membrane and a preparation method thereof. The PET membrane is prepared from the following raw materials in parts by weight: 50-100 parts of PET polyester chips, 2-10 parts of methoxypropyl acetate, 2-10 parts of ethyl acrylate, 1-20 parts of bis(2,2,6,6-tetramethyl-4-piperidyl)sebacate, 0.1-20 parts of bisbenzoxazole, 5-20 parts of nano-titania, 1-10 parts of RC-E60 silicon-free release agent, 0.1-4 parts of HANKINS NCP-2 and 3-20 parts of 2-(2-hydroxyl-3-tert butyl-5-methoxyphenyl)-5-chlorobenzotriazole. The PET membrane prepared by the preparation method can be used for blocking 99.0% or more of ultraviolet rays with the wavelength of 290nm to 400nm; the PET membrane is transparent, also has the functions of resisting ultraviolet rays, insulating heat and proofing radiation and has an excellent effect.

Description

technical field [0001] The invention relates to an anti-ultraviolet, heat-insulating and anti-radiation PET film and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields. [0003] 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. In the prior art, there are few industrial materials with anti-ultraviolet function. In the prior art, there is an anti-ultraviolet protective film called solar film. Its anti-ultraviolet function is achieved...
