Abstract

The present invention provides a preparation method of an evenly film-formed color liquid crystal light adjusting film, comprising the steps of preparing a mixture I for standby application; weighing10 to 30 parts by weight of spacers and adding them to the mixture I, thereby obtaining a color liquid crystal mixture; adding the color liquid crystal mixture to a coating lamination machine, by laminating an upper film and a lower film tightly through a laminating roller and pulling the films out through a pull roll, thereby obtaining a laminated film; and performing staged curing, thereby making the color liquid crystal light adjusting film via UV curing. The preparation process of the present invention is simple and reasonable. As compared with the prior art, by adjusting a laminating space and staged curing, the preparation method solves the problem of not ideal film-forming evenness and compactness of the color liquid crystal light adjusting film in the preparation process. By addingcolor fillers and spacers, the preparation method improves evenness of color distribution of the light adjusting film, thus further enhancing satisfaction with color of the color liquid crystal lightadjusting film.

Description

technical field [0001] The invention relates to the technical field of dimming films, in particular to a method for preparing a uniformly formed color liquid crystal dimming film. Background technique [0002] Liquid crystal dimming film is a new type of electronic light control product, which injects a liquid crystal / polymer hybrid material between two transparent conductive films. In the absence of an electric field, the liquid crystal dimming film is in an opaque state; At this time, the liquid crystal molecules are arranged in an orderly manner. At this time, the dimming film is converted from the opaque state, that is, the OFF state, to the transparent state, that is, the ON state. Quick conversion. Liquid crystal dimming film has broad application prospects in many aspects such as commerce, retail, medical and health, government agencies, and security. However, the ordinary color liquid crystal dimming film has the problems of high preparation cost, unsatisfactory fi...
