【摘要】 利用60Coγ射线对尼龙6/粘接聚乙烯/聚乙烯/粘接聚乙烯/尼龙6五层共挤出复合薄膜(尼龙6 复合薄膜)进行辐射交联改性。研究了辐射剂量对材料的各项性能的影响。结果表明:在10—50kGy 的辐射剂量范围内,尼龙6 复合薄膜仍然保持其原有地良好的阻隔性能;同时,材料的力学性能得到大大的提高;收缩率明显减小,大大提高了尼龙6 复合薄膜的尺寸稳定性。更多还原

【Abstract】 The nylon―6/adhesive PE/PE/ adhesive PE / nylon―6 composite film(nylon―6 composite film) was irradiated by Co γ―ray in order to get crosslinking modification. The effect of 60 irradiation dose on properties of nylon―6 composite film was studied. The results showed that the nylon―6 composite film could keep its original separation properties in irradiation dose of 10—50 kGy, the mechanical properties of the nylon―6 composite film was successfully improved,the contration ratio was distinctly reduced at the same time.Therefore the dimensions stabily of the nylon―6 composite film was considerably improved.更多还原
