NOVELTY - A composition containing 100 parts mass ethylene-vinyl acetate copolymer, 0.1-2 parts mass silane coupling agent (a), 0.1-2 parts mass silane coupling agent (b) and 0.01-0.2 parts mass organic peroxide is evenly mixed, extruded at 100-150 degrees C, cast, cooled, drawn, and coiled, to obtain silane crosslinked ethylene-vinyl acetate copolymer adhesive film. The silane coupling agent (a) is ethylene dimethoxysilane, ethylene bis(ethoxysilane), ethylene bis( beta -methoxyethoxy)silane and/or vinyl triacetoxysilane.    USE - Preparation of silane crosslinked ethylene-vinyl acetate copolymer adhesive film used for preparing solar battery component (claimed).    ADVANTAGE - The method economically provides solar battery component having improved laminating efficiency.    DETAILED DESCRIPTION - A composition containing 100 parts mass ethylene-vinyl acetate copolymer, 0.1-2 parts mass silane coupling agent (a), 0.1-2 parts mass silane coupling agent (b) and 0.01-0.2 parts mass organic peroxide is evenly mixed, extruded at 100-150 degrees C, cast, cooled, drawn, and coiled, to obtain silane crosslinked ethylene-vinyl acetate copolymer adhesive film. The silane coupling agent (a) is ethylene dimethoxysilane, ethylene bis(ethoxysilane), ethylene bis( beta -methoxyethoxy)silane and/or vinyl triacetoxysilane. The silane coupling agent (b) is vinyl trimethoxysilane, vinyl triethoxysilane, vinyl tris( beta -methoxyethoxy)silane, gamma -glycidoxypropyltrimethoxysilane dimethoxysilane, gamma -methacryloxypropyl trimethoxysilane, gamma -aminopropyl trimethoxysilane, gamma -aminopropyl triethoxysilane, gamma -chloropropyl dimethoxysilane and/or gamma -propyldimethoxysilane. An INDEPENDENT CLAIM is included for preparation of solar battery component, which involves laminating silane crosslinked ethylene-vinyl acetate copolymer adhesive film and back plate in laminating machine at 140-150 degrees C, vacuumizing for 5 hours, pressurizing for 51 minutes and pressing under pressure of 0.5-1 kg/cm2.
