IONIC RESIN ENCAPSULATION ADHESIVE FILM AND PREPARATION METHOD, LAMINATED STRUCTURE, AND PHOTOVOLTAIC MODULE

摘要

The present application relates to an ionic resin encapsulation adhesive film and a preparation method, a laminated structure, and a photovoltaic module. The ionic resin encapsulation adhesive film comprises an ionized functional layer, and the ionized functional layer comprises an ionic resin; the ionic resin comprises 50-99% of an ethylene-vinyl acetate copolymer or elastomer, 0.01-40% of an unsaturated metal carboxylate salt, and 0.01-5% of an initiator, based on the total mass content of 100 parts. The unsaturated metal carboxylate salt and the ethylene-vinyl acetate copolymer or elastomer in the adhesive film of the present application have good compatibility, and during use of the adhesive film, the initiator initiates a free radical reaction, so as to form a network structure in the ethylene-vinyl acetate copolymer or elastomer, thereby producing high volume resistivity, improving the anti-PID performance of modules, and maintaining the good light transmittance of the adhesive film.
