生物降解热塑性淀粉树脂薄膜及其制备方法
[技术领域]
本发明涉及降解树脂薄膜技术领域，具体地说是一种生物降解热塑性淀粉树脂薄膜及其制备方法。
[背景技术]
随着人们生活水平的逐步提高，人们的健康意识以及对环境保护的意识日益增强。目前，人们日常使用的一次性用品等，绝大部分是石油基塑料，其价格低廉，但均属于难以降解的产品，由于近年来这些产品的使用量逐渐增大，造成环境污染，影响了生态的平衡，越来越多的降解塑料制品开始涌现，然而目前的降解产品总是存在这样或者那样的不足。因此，生物可降解材料(塑料)是环境保护工程的一个重要组成部分。
[发明内容]
本发明的目的就是要解决上述的不足而提供一种生物降解热塑性淀粉树脂薄膜，通过采用特殊的原材料，此类原材料为绿色环保的生物聚乙烯等，从而生产的簿膜可以生物降解，生物环保，减少了二氧化碳的排放。
为实现上述目的设计一种生物降解热塑性淀粉树脂薄膜，按质量百分比计算，其原料的组成及含量如下：
作为优选，按质量百分比计算，上述原料的组成及含量如下：
该生物降解热塑性淀粉树脂薄膜的制备方法，包括以下步骤：将热塑性淀粉、茂金属、低密度聚乙烯、爽滑剂、高密度聚乙烯、颜料按上述质量百分比经混炼机混炼，加入吹膜机组，经吹膜挤出机进行塑化、挤出、吹涨、牵引、收卷工序，即可吹制成生物降解热塑性淀粉树脂薄膜。
本发明同现有技术相比，通过使用40-52％的生物原料，其主要作用是使薄膜在阳光下分解，并添加8-16％的茂金属原料提高强度，添加20-30％的低密度聚乙烯提高热封性，添加3-5％的爽滑剂提高爽滑性和开口性，添加4-6％的高密度原料提高挺度，添加5-8％的颜料以改变薄膜的颜色，该簿膜采用特殊的原材料，此类原材料为绿色环保的生物聚乙烯，并结合特殊的生产工艺，采用吹膜法，采用风冷的方式生产，使生产的簿膜可以生物降解，生物环保，减少二氧化碳的排放，避免环境污染，值得推广应用。
