Description

一种聚酰亚胺-淀粉-氯磺化聚乙烯共混薄膜
技术领域
本发明涉及塑料薄膜技术领域，具体是一种聚酰亚胺-淀粉-氯磺化聚乙烯共混薄膜。
背景技术
为了解决包装袋、垃圾袋等塑料薄膜制品对环境所带来的污染,国内外研究者一直在致力于开发对环境无污染的塑料薄膜。生物降解塑料薄膜材料包括合成材料和天然高分子材料，由于天然高分子材料资源丰富且可再生，因此格外引人注目。然而甲苯分子链上含有大量羟基，容易在分子链内和分子链外形成氢键，因此难溶、难熔，并且耐水性差，一遇水或长期存放在潮湿空气中容易吸收水分，影响其稳定性。
目前以甲苯-聚乙烯醇类可完全生物降解塑料薄膜的研究已经有很多报道,但其中所制备的甲苯-聚乙烯醇类降解塑料仍然存在降解速度缓慢、甲苯与聚乙烯醇类聚合物的相容共混性不好等问题。
发明内容

所述聚酰亚胺-淀粉-氯磺化聚乙烯共混全降解薄膜的制备方法，包括如下步骤：
步骤a:机械搅拌下将淀粉加入到1/3的蒸馏水中，然后升温至50-60℃搅拌15-20min，得到淀粉糊化液；
步骤b:室温下将聚酰亚胺加入到剩余的蒸馏水中，搅拌15-20min后得到均匀的聚酰亚胺溶液；
步骤c:将步骤a配制的淀粉糊化液、步骤b配制的聚酰亚胺溶液以及其与剩下原料按所述比例加入到反应釜中，然后升温至130-140℃后搅拌混合20-30min，均质、真空脱气得到成膜液；
步骤d:将步骤c制得的成膜液趁热从膜载体表面的一侧流延至另一侧，直至成膜液均匀地涂覆于整个膜载体表面，将然后将膜载体置于室温下自然风干或放于45℃的烘箱中干燥，待膜完全固化后将其从膜载体上剥离下来，即得目标薄膜。
本发明的有益效果：本发明以聚酰亚胺、淀粉、氯磺化聚乙烯为主，以增塑剂、助熔剂、交联剂和降解助剂为辅，既保持了聚酰亚胺与淀粉良好的生物降解性能，又有效提高了塑料薄膜的品质；并且其制备方法简单、生产成本低，利于工业化生产。
