文章简述了聚烯烃防老化技术进展。实验表明:引入金属离子螯合剂组成的复合光稳定体系BHW 1在农用聚烯烃棚膜中应用效果良好,具有更为均衡的光、热稳定性能;自然曝晒实验和大田实验证明复合受阻胺光稳定剂(HALS)的光稳定性能优于单组份光稳定剂,光稳定剂复合化是聚烯烃防老化最有成效的解决方式之一。。
The article briefly describes the progress of polyolefin anti-aging technology. Experiments show that: the introduction of metal chelating agent composite light stabilizing system BHW 1 in the agricultural polyolefin shed film application effect is good, with a more balanced light and thermal stability; natural exposure experiments and field experiments show that compound hindered amine light stability The light stability of HALS is better than that of one-component light stabilizer. The light stabilizer is one of the most effective ways to prevent the aging of polyolefins. .
