[0003] Liquid crystal polymer films are mostly used as high-grade decorative films, and their application range is narrow; the coating method of liquid crystal polymer films is usually vacuum coating, which has high cost, thin film layer, and limited applicability. When the plated liquid crystal polymer film is used as a decorative film in lower-end occasions, it is easy to cause waste of cost

Abstract
The invention relates to the technical field of coating, in particular to a liquid crystal high-molecular polymer coating transfer process based on an optical lens or a polarizing film. The process comprises the following steps of S1, mounting a release film on a coating machine, winding the release film around a roll shaft of the coating machine, and enabling the release film to be in a straightened state; S2, preparing liquid crystal high-molecular polymer slurry, coating the release film with the liquid crystal high-molecular polymer slurry through the coating machine in S1, and forming a liquid crystal high-molecular polymer film on the release film after coating of the liquid crystal high-molecular polymer slurry is completed; S3, coating the surface of the optical lens or the polarizing film with a layer of shadowless glue, and pasting the release film and the liquid crystal high-molecular polymer film obtained in S2 to the shadowless glue; S4, irradiating the liquid crystal high-molecular polymer film pasted to the shadowless glue in S3 through a UV lamp, so that the liquid crystal high-molecular polymer film is completely attached to the shadowless glue; and S5, rolling back the release film, so that the release film is stripped off the liquid crystal high-molecular polymer film.
Description
technical field [0001] The invention relates to the field of film coating technology, in particular to a liquid crystal polymer coating transfer process based on optical lenses or polarizing films. Background technique [0002] The liquid crystal polymer was originally a lyotropic polyparaphenylene terephthalamide developed by DuPont Company of the United States. Because this type of polymer can only be processed in solution and cannot be melted, it can only be used as fiber and coating, and it is a special engineering plastic raw material. [0003] Liquid crystal polymer films are mostly used as high-grade decorative films, and their application range is narrow; the coating method of liquid crystal polymer films is usually vacuum coating, which has high cost, thin film layer, and limited applicability. When the plated liquid crystal polymer film is used as a decorative film in lower-grade occasions, it is easy to cause waste of cost. Contents of the invention [0004] 1...
