The invention relates to the technical field of packaging
adhesive films, in particular to an anti-PID packaging
adhesive film for a double-sided PREC battery and a preparation method of the anti-PIDpackaging
adhesive film. The packaging adhesive film comprises an upper anti-polarization transparent EVA layer and a lower quick-curing high-
cut-off transparent EVA layer, the anti-polarization transparent EVA layer comprises the following components in percentage by
mass: the content of the
ethylene-
vinyl acetate copolymer resin is 80%-89%, the content of the
antioxidant is 0.01%-1%, the contentof the light stabilizer is 0.01%-1%, the content of the crosslinking agent is 1%-2%, the content of the
silane coupling agent is 0.1%-2%, the content of the inorganic anti-polarization material is 0.5%-2%, and the content of the organic anti-polarization material is 2%-8%; the PID-resistant packaging adhesive film for the double-sided PERC battery has a good PID-resistant effect on a double-sidedPREC battery single-
package assembly and has the characteristic of good
assembly reliability; meanwhile, a rapid curing cross-linking
system is adopted so as to effectively shorten the
assembly laminating time and greatly improve the assembly end production efficiency; in addition, the material cost of the co-
extrusion adhesive film is relatively low, thereby being more beneficial to promoting photovoltaic equal-price networking.
