Reusable release paper for perfluorinated ion exchange membrane

The invention belongs to the technical field of release paper, and particularly relates to reusable release paper for a perfluorinated ion exchange membrane. The release paper comprises raw paper and a release agent coated on the surface of the raw paper, the release agent comprises an organic silicon release agent, the raw paper is raw white kraft paper, the degree of finish of the raw paper is 2-5 microns, and the air permeability of the release paper is 0.05-1.3 microns/(Pa.s). By controlling the air permeability of the raw paper and the use amount of the release agent, the release paper disclosed by the invention has good tensile strength, tearing strength and use performance; the release paper is not easy to tear, is high in repeated utilization rate, and is beneficial to environmental protection and reduction of carbon emission; the perfluorinated ion exchange membrane can be prepared at high temperature, and the prepared perfluorinated ion exchange membrane is low in thermal shrinkage rate and free of
