聚合型受阻胺光稳定剂在温室覆盖薄膜中的应用研究

Research on the Application of Polymeric Hindered Amine Light Stabilizer in Greenhouse Film

以聚合型受阻胺光稳定剂 Uvinul 5050H为主,辅以新型抗氧剂 AOD 组成农用聚乙烯(PE)棚膜防老化体系。大田应用实验表明,该体系的耐候性能优异。其中采用0.3%Uvinul 5050H 的60μm厚 PE 单层薄膜能够在大田应用12个月以上;含0.3%Uvinul 5050H 的100 μm厚 PE 单层薄膜能够在户外使用18个月以上。含 Uvinul5050H 的园艺玫瑰生产专用膜,在很好的管理和较少使用硫磺熏蒸的条件下能够使用12个月。

The anti-aging additive system for PE greenhouse film was formulated from polymeric hindered amine light stabilizer Uvinul 5050H, and assisted with a novel antioxidant AOD. The excellent performance of PE film with the above anti-aging system was observed. The 60 μm PE single layer film with 0.3 % Uvinul 5050H could be used for more than 12 months, while the 100 μm PE single-layer PE film with 0.3 % Uvinul 5050H could be used for more than 18 months. The greenhouse film for planting roses with Uvinul 5050H could be used for more than 12 months in better management with less sulfur suffocating.
