ROLL-TO-ROLL SILVER FILM COATING APPARATUS AND SILVER FILM COATING METHOD USING SAME

摘要

The present invention relates to a roll-to-roll silver film coating apparatus, capable of realizing continuous or high speed coating for a flexible base, and a silver film coating method using the same. According to one embodiment of the present invention, the roll-to-roll silver film coating apparatus comprises: a substrate unwinding unit to continuously feed a substrate to a silver film coating line, in which a silver film coating work for the substrate is advanced; a surface modification unit to modify a surface of the substrate in order to secure bonding force between silver and the substrate fed from the unwinding unit; a silver film coating tank, wherein a silver mirror reaction solution and a reducing agent are stored and the substrate completing a substrate surface modification step is immersed; a water washing tank, wherein deionized water is stored and the substrate completing a silver film coating step is immersed and washed; a drying unit to dry the substrate completing a washing process; and a rewinding unit disposed on a side opposite to an unwinding device to recover the substrate completing a drying process.;COPYRIGHT KIPO 2018
