摘要
受阻胺光稳定剂(HALS)是一种被广泛应用在塑料行业的新型高效助剂。本文综述了HALS捕获自由基、氢过氧化物分解、猝灭单线态氧三种作用机理,以及其在聚烯烃防光老化、防热老化方面的应用,并对HALS的发展进行了展望。
Hindered amine light stabilizer(HALS)is a new type of high efficiency additive widely used in plastics industry.In this paper,the three mechanisms of HALS for capturing free radicals,decomposition of hydroperoxides,quenching singlet oxygen are introduced.Moreover,the application of HALS in anti-aging of light and heat of polyolefins are reviewed.Finally,the development trend of HALS is also prospected.
