MANUFACTURING METHOD FOR REAR PROTECTION SHEET FOR SOLAR CELL MODULE

摘要

The present invention relates to a manufacturing method for a rear protection sheet for a solar cell module, comprising the following steps: unwinding a base film that has been wound on a roller; coating one side of said unwound base film with an adhesive; drying said base film coated with an adhesive; stacking a fluorine-based film on the side of said base film that has been coated with an adhesive and dried; a first aging of said base film on which said fluorine-based film has been stacked; forming an extruded resin film through melt extrusion of a polymer resin onto the rear surface of said base film, on which said fluorine-based film has been stacked, after the conclusion of said aging process; and a second aging of said base film on which said extruded resin film has been formed.
