Notacoria in solar energy photovoltaic panel is as direct and external environment bump contact photovoltaic encapsulation material, and it is required possess the performances such as the resistance to long-term ageing (damp and hot, xeothermic, ultraviolet) of brilliance, resistance to electric insulation, vapor water barriers. Existing modal notacoria is fluorine-containing notacoria, and wherein fluorine-containing notacoria is divided into again double-side fluorine (TPT) and one side fluorine-containing (TPE) notacoria, wherein, and the basic structure of double-side fluorine back film substantially fluorine-containing layer/glue/PET/ glue/fluorine-containing layer. But owing to technology of preparing and the process for modifying surface of fluorine-containing notacoria are all monopolized by external major company, domestic have not been achievable production domesticization, this also makes domestic photovoltaic notacoria industry be limited by foreign-made business for a long time, causes notacoria cost to remain high, and very difficult import.
Owing to there is adhesive inside it in notacoria, and the quality level of adhesive differs, in addition combination process is very different, in the life-time service process of battery component open air, notacoria is by the combined influence of humidity with temperature dual factor, easily there is the infringements such as glue line hydrolysis, ultimately result in and peel off between layers, it is difficult to meet the reliability requirement that battery component is long-term. Domestic Ye Zengyouguo enterprise attempts going the polyurethane adopting some common, epoxies or acrylic compounds adhesive to go to replace external used adhesive, but these adhesives are all easily aging, cannot meet life requirement even more of a specified duration in 25 years in performance. Therefore, develop the aging resistance notacoria product that a class has the low cost of excellent long-term weatherability performance, be direction and the trend of the exploitation of current notacoria and technical development.
