NOVELTY - Preparation of high-efficiency UV-resisting ethylene vinyl acetate (EVA) adhesive film comprises uniformly mixing EVA, crosslinker, antioxidant, UV absorbent, light stabilizer, gamma -aminopropyl triethoxysilane, vinyl acetate and europium acrylate; pouring the mixture to twin-screw extruding-pelleting machine; controlling the mixing temperature, carrying out mixing and pelleting; and making the particle pass through the film-forming system to obtain the adhesive film.    USE - Preparation of high-efficiency UV-resisting EVA adhesive film for packaging solar battery (claimed).    ADVANTAGE - Compared with existing technology, europium element is introduced to the packaging formulation, which is good for converting UV ray into visible light and improving light utilization rate of the solar battery component. The prepared adhesive film has properties as the traditional adhesive film for packaging solar battery such as strong adhesive strength, high visible light transmissivity and high-temperature aging resistance and high UV aging resistance.    DETAILED DESCRIPTION - Preparation of high-efficiency UV-resisting EVA adhesive film comprises:    (A) uniformly mixing ethylene vinyl acetate (EVA), crosslinker, antioxidant, UV absorbent, light stabilizer, gamma -aminopropyl triethoxysilane, vinyl acetate and europium acrylate; and    (B) pouring the mixture to twin-screw extruding-pelleting machine; controlling the mixing temperature, carrying out mixing and pelleting, where the twin-screw extruder is divided into inlet section, middle section and outlet section; and temperature is 81-84 degrees C, 85-90 degrees C and 84-86 degrees C; making the particle pass through the film-forming system to obtain the adhesive film.    The melt index of the EVA is 30-50 g/10 minutes under conditions that the VA content is 33 and the temperature is 190 degrees C. The crosslinker is triphenyl methane-4,4',4''-triisocyanate or t-butylperbenzoate (TBPB). The antioxidant is mixture of 2,6-di-tert-butyl-4-methylphenol (antioxidant 264) and tetra( beta -(3, 5-di-tert-butyl-4-hydroxyphenyl) propionic acid) pentaerythritol ester (antioxidant 1010). The UV absorbent is mixture of N-(ethoxy carboxyphenyl)-N'-methyl-N'-phenyl methyl ether and 2-hydroxy-4-n-octyl benzophenone. The light stabilizer is di(1-octyl-2,2,6,6-tetramethyl-4-piperidyl) sebacate or di(2,2,6,6-tetramethyl-4-piperidyl) sebacate. An INDEPENDENT CLAIM is included for a high-efficiency UV-resisting EVA adhesive film for packaging solar battery, which is prepared by the above method.
