Description

一种硬弹性聚丙烯膜
技术领域
本发明涉及包装膜材料生产工艺，特别是涉及一种硬弹性聚丙烯膜。
背景技术
硬弹性材料是近年来兴起的一种新型弹性体，由于其具备较高的回弹性、良好的低温弹性、高模量及拉伸成孔性能，获得了广泛关注和应用。如利用其高模量和高弹性可制备硬弹性纤维，用于制造各种弹性织物，而利用其拉伸时形成微孔的特性可以制成平板或中空纤维微孔膜材料，用于物质的分离、浓缩、净化和回收等。聚烯烃材料由于良好的机械性能和化学稳定性，由聚乙烯和聚丙烯制备的微孔膜广泛用于锂离子电池隔膜领域，当前，锂离子电池的电极材料已经基本实现国产，而作为重要组成部分的电池隔膜材料仍主要依靠进口，生产此类隔膜材料的关键技术被日本及欧美国家垄断。聚丙烯微孔膜作为功能性高分子薄膜，具备广阔的市场前景和经济效益，属于高附加值的产品。
