弹性体改性PE膜的结构、性能及应用

Structure,Property and Application of Elastomer Modified PE Film

本文研究了弹性体改性ＰＥ膜的结构、性能及应用。研究结果表明：ＰＥ／弹性体膜具有两相结构；分散助剂有利于弹性体在ＰＥ基体中的分散并改善加工性能；弹性体还可以有效地提高ＰＥ膜的耐穿刺性；ＰＥ／弹性体膜可用于中国北方草原的牧草青贮。

In this paper,the structure,property and application of elastomer modified PE film were investigated in detail.The experiment results showed that PE/elastomer films were of two-phase structure,dispersion agent could obviously improve the dispersion of elastomer in PE matrix and processing properties of the system,Elastomer could increase the impact properties of the film, and the film could be used in grass silage in North China grassland.
