Description

一种高强度环保降解塑料薄膜
技术领域：
本发明涉及包装材料领域，具体讲是一种高强度环保降解塑料薄膜。
背景技术：
塑料薄膜，即用聚氯乙烯、聚乙烯、聚丙烯、聚苯乙烯以及其他树脂制成的薄膜，用于包装，以及用作覆膜层。塑料包装及塑料包装产品在市场上所占的份额越来越大，特别是复合塑料软包装，已经广泛地应用于食品、医药、化工等领域，其中又以食品包装所占比例最大，比如饮料包装、速冻食品包装、蒸煮食品包装、快餐食品包装等，这些产品都给人们生活带来了极大的便利。
可降解塑料是利用植物秸杆等制成的对人体和环境友好的物品，不同于三大合成的塑料，废弃后，在生物环境的作用下，可以自行分解，无论对人还是环境都无害，属于绿色包装。可降解塑料袋是“能降解、易降解”的一种一次性购物袋。可降解塑料袋从原料和分解因素的不同，可分为两种：一种是以聚乙烯塑料为主，掺混淀粉等生物降解剂制成的塑料袋，也叫做可生物降解型塑料袋。这种塑料袋主要靠微生物作用而分解。但这种可降解塑料只能将大块的塑料降解成较小的塑料块，塑料分子的成分并没有完全消失，所以它的降解是有限度的。另一种是以聚乙烯塑料为主，掺混光降解剂和碳酸钙等矿物粉体制成的塑料袋，也叫做光降解型塑料袋。这种塑料袋是在太阳光的作用下分解。其缺点是降解时间因日照和气候变化难以预测，因而无法控制降解时间。
发明内容：
本发明所要解决的技术问题是，提供一种高强度环保降解塑料薄膜，该薄膜具有优良的耐水、耐湿性能和良好的力学性能，冲击强度高，承重性能好，使用范围时间长，并且具有可降解性，降解产物对环境无污染，不仅降低包装袋的成本，还减少了对环境的污染，绿色环保。
本发明的技术解决方案是，提供一种高强度环保降解塑料薄膜，按质量百分比计，包括如下组分，高密度聚乙烯20-40％、PET10-29％、聚乙烯醇2-8％、聚氨酯1-19％、乙醇胺0.5-2％、甘露醇0.5-2％、乙基纤维素0.5-2％、植物纤维1-5％、十二烷基丁二酸酯1-5、PBM降解材料1-10％、水杨酸苯酯0.5-2％、明胶1-3％、普鲁兰多糖0.1-1％、尿素0.1-1％、淀粉5-10&、二氧化硅0.2-1％、增塑剂0.3-1.1％、偶联剂0.2-1.2％。
作为优选，还包括1-3％的尼龙纤维和1-3％的亚麻纤维。
进一步的，淀粉为玉米淀粉。
采用以上方案后与现有技术相比，本发明具有以下优点：生产而出的高强度环保降解塑料薄膜，具有优良的耐水、耐湿性能和良好的力学性能，冲击强度高，承重性能好，使用范围时间长，降解效果好，环保。
具体实施方式：
下面就具体实施方式对本发明作进一步说明：
