摘要
研究了由光敏剂硬脂酸铁和抗氧剂 10 76组成的光降解体系的光 /生物双降解聚乙烯薄膜在紫外灯辐照下的断裂伸长率保留率、分子量、脆化期、诱导期等的变化规律。结果表明 ,硬脂酸铁具有促进光降解和抑制交联的双重作用 ;抗氧剂 10 76对薄膜光降解作用的影响没有硬脂酸铁显著 ;由它们组成的光降解体系具有较好的时控光降解效应 。
It studied reserved elongation at break, molecular weight, induction period and embrittlement time of photo-biodegradable PE films with various amounts of photosensitizer Fe(St)_3 and antioxidant1076. The results indicated that Fe(St)_3 could accelerate photo-degradation and restrain crosslinking, the effects of antioxidant1076 on films' photo-degradation was weaker than on Fe(St)_3; every light-degradation system had obvious time-controlled effect and could obviously influence the induction period.
