Abstract
The invention discloses an anti-aging protective film, which includes a PET base membrane. The surface of the base membrane is coated with a polyurethane coating, and the polyurethane coating comprises the following components mixed by weight: 50-55 parts of a polyurethane prepolymer; 3-5 parts of 2, 2, 6, 6-tetramethyl piperidine-1-oxygen free radical; 35-40 parts of a plasticizer; and 6-8 parts of a coupling agent. According to the anti-aging protective film provided by the invention, the 2, 2, 6, 6-tetramethyl piperidine-1-oxygen free radical has a very obvious inhibition effect on PET polymerization, and can generate a synergistic effect with the plasticizer and coupling agent so as to make the obtained PET film have good aging resistance. The aging speed of the film drops greatly in the process of using, and the service life of the anti-aging protective film is prolonged.
Description
technical field [0001] The invention relates to an anti-aging protective film. Background technique [0002] In the prior art, during the long-term use of the protective film on the liquid crystal display, due to continuous radiation, it will age and turn yellow, resulting in a decrease in light transmittance, affecting the line of sight, and prone to refraction and random reflection of light. fatigue. Contents of the invention [0003] In order to prevent the aging of the protective film and prolong the service life of the protective film, the invention provides an anti-aging protective film. [0004] In order to solve the above technical problems, the technical solution of the present invention is: an anti-aging protective film, comprising a base film of PET (polyethylene terephthalate) material, the surface of the base film is coated with a polyurethane coating, The polyurethane coating comprises the following components mixed in parts by weight: polyurethane prepolym...
