Description

一种能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30-55％，聚丙乙烯5-10％，聚乙烯5-8％，聚己内酯与聚羟基丁酸脂共聚物3-4％，成核剂2-5％，能改善制品透明度的成核剂2-6％，耐久性增塑剂2-3％，改性辅料2-5％，植物糖5-8％，抗氧剂1-4％，稳定剂3-5％，防水剂1-3％，吸湿剂1-3％，润滑剂1-2％，脱模剂1-3％，降解控制剂2-6％。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——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％。
