Abstract

The invention discloses an EVA adhesive film for solar cells and a preparation method thereof. The adhesive film includes the following raw materials: ethylene-vinyl acetate copolymer, sodium phenylacetate, nano-carbon, aluminum foam, copper foam, phenalkamine, ethylmethyltrichlorosilane, aluminum tripolyphosphate, ethylene peroxide resin, alkyd resin , castor oil, acetic anhydride, cellulose acetate, carbon tetrachloride, polypropylene alcohol. Weigh raw materials; sodium phenylacetate, nano-carbon, phenalkamine, trichlorosilane, aluminum tripolyphosphate, ethylene peroxide resin, alkyd resin, castor oil, acetic anhydride, cellulose acetate, carbon tetrachloride , polypropanol into the reaction kettle, heating and melting while stirring to obtain the first mixture; put ethylene-vinyl acetate copolymer and the first mixture into the three-roll blender to extrude the masterbatch, and stretch it on the copper drum to obtain the film. The EVA adhesive film of the invention has high transparency, good weather resistance, low melting point and anti-aging, and the solar cell prepared by using the adhesive film has a long service life.

Description
