A kind of light stabilizer combination for photovoltaic EVA adhesive film |
| abstract |
The present invention provides a kind of as including the light stabilizer combination for being used for EVA adhesive film composed by hindered amine light stabilizer and cinnamate derivative ultraviolet absorbing agent, wherein, the weight ratio of hindered amine light stabilizer and cinnamate derivative ultraviolet absorbing agent is (0.5-2): 1, additive amount of the light stabilizer combination in photovoltaic EVA adhesive film is the 0.2-1.2% of EVA resin weight.Light stabilizer combination of the invention is used in EVA adhesive film, EVA adhesive film is superior to the existing light stabilizer system as composed by hindered amine light stabilizer and benzophenone or benzotriazole ultraviolet absorbent in initial light transmission, heat oxygen aging resistance and heat and moisture aging resistance. |
