制备方法与用途

用途

紫外线吸收剂 UV-366 具有分子量大、不易挥发和耐抽出的特点，且易于加工。这种材料的防紫外效率高，其紫外摩尔消光系数是二苯甲酮类紫外线吸收剂的2.6倍，并且是传统苯并三唑（烷基酚取代衍生物）类紫外线吸收剂的1.8倍。此外，UV-366 具有较强的吸附性，尤其对超细纤维的吸附性能优于三嗪类紫外线吸收剂，特别适用于聚酯纤维。

  An extruded solar power back panel: an inner, middle, and outer layer arranged from the inside to the outside sequentially with a mass ratio of 10-40:40-80:10-40. Total thickness of the extruded solar power back panel is 0.1-0.6 mm. Highly rigid polypropylene added to inner layer ensures the bonding force between back panel and adhesive film, and improves inter-layer bonding force between back panel and polypropylene material in middle layer. Polyethylene, or a co-polymer thereof, added to the middle and outer layers, achieves excellent adhesion to polyethylene in inner layer, further improving inter-layer bonding force and low temperature thermal shock resistance of back panel. Added grafting material improves uniformity and inter-layer bonding force of product, increases the surface tension of back panel after corona treatment, and increases bonding force between back panel and silica gel used for sealing frame of solar cell.
