| titleOfInvention | A kind of weather-resistant polyester film for solar backboard |
| abstract | The invention belongs to the technical field of polymer materials, and in particular relates to a weather-resistant polyester film for a solar backboard. The thin-film composite fluorine-containing solar backsheet with PET film as the base film is compounded by polyurethane adhesive. The phenomenon of thermal expansion and contraction leads to curling and deformation of the composite film, and even delamination, which seriously affects the weather resistance and mechanical strength of the solar backsheet. In view of the above problems, the present invention provides a weather-resistant polyester film for solar backplanes, which is a three-layer co-extruded film, which includes a wear-resistant layer, a transition layer and an insulating layer from the outside to the inside, and its wear-resistant layer, transition layer, POE-g-MAH is added to the insulating layer, which can effectively prevent the interlayer phase separation structure between the wear-resistant layer, transition layer, and insulating layer, and is more conducive to improving the wear-resistant layer, transition layer, and insulating layer. interlayer cohesion. |
