Description

一种能完全降解的仿纸材料的制备方法
技术领域
本发明涉及淀粉、直链淀粉或支链淀粉或它们的衍生物或降解产物的组合物，以及含有高分子物质的薄膜或片材的制造，尤其涉及一种能完全降解的仿纸材料的制备方法。
背景技术
现有广泛用于包装业的大部分塑料，不能自降解，其废弃物严重污染人类和动植物的生存环境。在石油化学塑料中掺入淀粉一类的天然可降解大分子，可以缩短塑料降解的周期，其实只是在外形上破碎。另一种以完全可降解的天然纤维素材料制成的纸容器，存在耐水性、耐油性差，成本高，强度低的缺陷，应用范围有限。
发明内容
一种能完全降解的仿纸材料的制备方法，其特征是各组分和百分比含量分别是：淀粉50-60％，聚丙乙烯5-8％，聚乙烯5-6％，聚己内酯与聚羟基丁酸脂共聚物3-5％，成核剂2-4％，能改善制品透明度的成核剂2-5％，耐久性增塑剂1-3％，改性辅料1-5％，植物糖3-8％，抗氧剂2-4％，稳定剂3-6％，防水剂1-2％，吸湿剂1-2％，润滑剂1-3％，脱模剂2-3％，降解控制剂2-5％。根据以上所述的一种能完全降解的仿纸材料的制备方法，其特征在于上述淀粉为天然高分子淀粉，它为玉米淀粉、小麦淀粉、木薯淀粉或水稻淀粉。植物糖为木糖、麦芽糖或淀粉糖。
本发明以具有良好生物降解性能的高分子化合物一一淀粉为主要成分，加入可生物降解的聚合物，在特定的温度、压力下混炼，并在混合体中添加成核剂、增塑剂、抗氧剂、稳定剂、防水剂、吸湿剂、润滑剂和脱模剂，通过物理与化学改性，进行分子结构修饰与自组复合，从耐高温、耐水、耐油、耐渗漏、抗冲击强度、不变形、柔韧性等方面，提高其适用性能，并使其在生物环境中被腐蚀、吸收、降解、磨损和失效，从而达到全降解的目的。
具体实施方式
一种能完全降解的仿纸材料的制备方法，其特征是各组分和百分比含量分别是：淀粉53％，聚丙乙烯5％，聚乙烯6％，聚己内酯与聚羟基丁酸脂共聚物4％，成核剂3％，能改善制品透明度的成核剂2％，耐久性增塑剂2％，改性辅料5％，植物糖5％，抗氧剂2％，稳定剂3％，防水剂1％，吸湿剂1％，润滑剂1％，脱模剂2％，降解控制剂2％。
