Description

水溶性环保地膜专用料
技术领域
本发明属于化工合成技术领域，具体涉及一种水溶性环保地膜专用料。
背景技术
淀粉基生物降解塑料，是淀粉经过改性、接枝反应后与其他聚合物共混加工而成的一种塑料产品，在工业上可以代替一般通用塑料等，可以用作包装材料，防震材料，食品容器，玩具等。PVA是唯一可被细菌作为碳源和能源利用的乙烯基聚合物，在细菌和酶的作用下，46天可降解75％，属于一种生物可降解高分子材料,可由非石油路线大规模生产，价格低廉，其耐油、耐溶剂及气体阻隔性能出众，在食品、药品包装方面具有独特优势。PVA的应用基于溶液法，通过流延成膜制备薄膜材料。
而目前随着农业的发展，地膜的使用越来越普及，使用面积也越来越广，但是白色污染也越来越严重，，例如大面积种植的棉花，种植过程中都需要使用地膜，但是使用结束后地膜都留在了地里，造成了严重的白色污染；
当然目前市面上也有一些降解地膜，可是降解效果并不好，不能有效实现目的，降解周期也非常长，达不到预期的环保效果。
发明内容
根据现有技术不足，本发明所要解决的技术问题是：提供一种水溶性环保地膜专用料，使得淀粉和PVA有机结合，产品功能性优良，也能够有效降解，环保性能非常良好，降解周期比较短。
本发明所述的水溶性环保地膜专用料，由如下重量百分比的原料制成：
所述的PVA为PVA17-88、PVA17-99、PVA20-99和PVA20-88中的一种或几种。
所述的淀粉为玉米淀粉、木薯淀粉或者红薯淀粉。
所述的聚乙二醇分子量为200-10000。
本发明的有益效果是：
1、制得的产品柔韧平滑、耐油、耐溶剂、耐磨耗、气体阻透性好，用途广泛；
2、淀粉能够得到有效降解，不会造成环境污染；
3、制备的产品性能优良，用量少，成本低，易生产，能增强膜强度、透明度等。
