NOVELTY - Preparation of high transparent ultraviolet light ethylene vinyl acetate (EVA) adhesive film comprises: taking EVA copolymer as base material, adding crosslinking curing agent and coupling agent, mixing uniformly in high speed mixer; adding antioxidant and light stabilizer, high speed stirring; transferring mixture through automatic sucking machine into double screw extruder and extruding at 80-95 degrees C, casting, cooling, drawing and winding to obtain EVA adhesive film.    USE - Method for preparing high transparent ultraviolet light ethylene vinyl acetate (EVA) adhesive film for packaging solar battery (claimed).    ADVANTAGE - The film has strong ultraviolet light transmission capacity and good aging resistance. It improves photoelectric conversion efficiency of photovoltaic assembly.    DETAILED DESCRIPTION - Preparation of high transparent ultraviolet light ethylene vinyl acetate (EVA) adhesive film for packaging solar battery comprises: taking EVA copolymer as base material, adding crosslinking curing agent and coupling agent, mixing uniformly in high speed mixer; adding antioxidant and light stabilizer, high speed stirring; transferring mixture through automatic sucking machine into double screw extruder and extruding at 80-95 degrees C, casting, cooling, drawing and winding to obtain the EVA adhesive film. The film comprises: 100 pts. wt. EVA, 0.4-1 pt. wt. crosslinking curing agent, 0.15-0.4 pt. wt. coupling agent, 0.1-0.3 pt. wt. composite antioxidant and 0.1-0.5 pt. wt. light stabilizer. The EVA contains 28 wt.% vinyl acetate with 30 g/10 minutes melting index at 190 degrees C. The crosslinking curing agent is t-butyl peroxy-2-ethylhexyl carbonate and 2,5-dimethyl-2,5-bis(t-butylperoxy)hexane. The antioxidant is beta -(3,5-di-tert-butyl-4-hydroxyphenyl)propionate n-octadecanol ester, tetra-(3-(3,5-di-tert-butylphenyl)propionate)pentaerythritol ester and tri-(2,4-di-tert-butylphenyl)phosphite mixture. The light stabilizer contains 20-45 wt.% first component and second component. The first components is poly(1-(2'-hydroxyethyl)-2,2,6,6-tetramethyl-4-hydroxy-piperidinol succinate) or poly((6-((1,1,3,3-tetramethylbutyl)amino)-1,3,5-triazine-2,4-diyl)((2,2,6,6-tetramethyl-4-piperidyl)imino)-1,6-hexanediyl((2,2,6,6-tetramethyl-4-piperidyl)imino)). The second component is bis (1,2,2,6,6-pentamethyl-4-piperidinyl)-sebacate and (2,2,6,6-tetramethyl-4-piperidyl)sebacate.
