| 摘 要： | 选用乙烯-乙烯醇共聚物（EVOH）、聚酰胺6（PA6）、茂金属聚乙烯（mPE）和改性线形低密度聚乙烯（PE-LLD）为原料，制备了3种三层共挤阻透薄膜PA6/EVOH/PA6、PA6/PE-LLD/mPE和EVOH/PE-LLD/mPE。通过对原料树脂热性能与流变性能的分析，探讨了三层共挤薄膜的最佳加工工艺。结果表明，所得3种共挤薄膜中以PA6/EVOH/PA6三层共挤薄膜的力学性能和氦气阻透性能最佳。

| Abstract: | Using ethylene/vinyl acetate copolymer(EVOH),polyamide 6(PA6),metallocene polyethylene(mPE) and linear low density polyethylene(PE-LLD) as raw materials,PA6/EVOH/PA6,PA6/PE-LLD/mPE and EVOH/PE-LLD/mPE three-layer barrier films were prepared via co-extrusion in this paper.The optimal processing technology of three-layer barrier films was obtained by analyzing thermal and rheological properties of raw materials.The results showed that the mechanical and helium barrier properties of PA6/EVOH/PA6 films were the... |
