一种太阳能电池背板聚酯薄膜及其制备方法
摘要：
本发明的目的是提供一种太阳能电池背板聚酯薄膜，其按重量份计的包括：瓶级聚酯切片70‑90份和聚酯母料切片5‑8份。其中，聚酯母料切片由以下组分制备得到，所述组分按重量份计的包括：对苯二甲酸70份、乙二醇30份、氧化铝2‑4份、硅酸钙0.5‑1.5份、纳米氧化锌0.5‑1.5份、抗氧剂0.5‑1.5份、光稳定剂2‑3份和催化剂3‑5份。本发明提供的太阳能电池背板聚酯薄膜，不仅有较高的反射率、耐湿热老化性好、表面张力大、易于粘结，并且具有优良的阻水性和阻燃性。
摘要（英）：

The invention provides a weather-resistant solar cell backboard. A base layer of the backboard is a polyester thin film, and the polyester thin film is prepared from, by weight, 70-90 parts of bottle-grade polyester chips and 5-8 parts of polyester masterbatch chips; by controlling the content and mass ratio of all the components in the polyester thin film, the prepared polyester thin film has high reflectivity, good moisture and heat aging resistance and excellent water resistance and flame retardancy, and therefore the corresponding performance of the solar cell backboard is improved.
