▎ 摘　　要

NOVELTY - Flexible electric heating demisting optical film, comprises first transparent base film (2), a second transparent base film (6), a first transparent conductive bottom coating (3), a second transparent conductive bottom coating (5), a transparent electric heating layer (4), pressure-sensitive adhesive layer (7) and release film (11). The one side of the first transparent base film is formed first transparent conductive bottom coating. The opposite side of second transparent base film and the first transparent conductive bottom coating is formed the second transparent conductive bottom coating, the first transparent conductive bottom coating and the second transparent conductive bottom coating. The transparent electric heating layer is arranged between the conductive bottom coatings. The pressure-sensitive adhesive layer is formed on the other side of the second transparent base film, and the release film is adhered on the pressure-sensitive adhesive layer. USE - Flexible electric heating demisting optical film used in bathroom mirror, automobile window, glass and showcase window. ADVANTAGE - The flexible electric heating demisting optical film has good transparency and conductivity, simple manufacturing process and cost-effective. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing flexible electric heating demisting optical film, which involves: (1) preparing a first transparent base film and a second transparent base film, respectively coating transparent conductive base coats on the surfaces of the first transparent base film and the second transparent base film, drying, respectively forming a first transparent conductive base coat and a second transparent conductive base coat on the surfaces of the first transparent base film and the second transparent base film, and rolling to obtain a first coiled material A and a second coiled material A; (2) taking the first coiled material A and the second coiled material A, respectively coating transparent electric heating layers on the surfaces of the first transparent conductive bottom coating and the second transparent conductive bottom coating, drying and rolling to obtain a first coiled material B and a second coiled material B; (3) taking the first coiled material B and the second coiled material B, oppositely pasting the transparent electric heating layer of the first coiled material B and the transparent electric heating layer of the second coiled material B, and rolling to obtain a coiled material C; (4) coating a pressure-sensitive adhesive on one side of the coiled material C, drying to form a pressure-sensitive adhesive layer, attaching a release film on the pressure-sensitive adhesive layer, rolling to obtain a coiled material D, and cutting the coiled material D to obtain target film.
