Abstract
本发明公开了一种纳米氧化锌增强淀粉/PBAT可降解材料及其制备方法,该包装膜由以下按重量份配比的原料制成:淀粉10‑30份,PBAT 70‑90份,甘油3‑12份,脱模剂0.3‑1.2份,纳米氧化锌0‑2份,月桂酸0.2‑1.5份,相容剂0.1‑0.9份,其中,二氯甲烷的用量为其体积与PBAT的质量比为4~8mL:1g。本发明在淀粉糊化过程中加入甘油、月桂酸和相容剂对其进行改性从而制得塑化改性淀粉,然后以淀粉和PBAT为成膜基材,借助二氯甲烷溶剂,使PBAT完全溶解,淀粉和纳米氧化锌均匀分散在溶剂中,并加入脱模剂,最终制得纳米氧化锌增强木薯淀粉/PBAT薄膜。该制膜工艺简单易行,制得的薄膜具有良好的机械性能和阻水性、较低的透光率和吸水率、较高的接触角,并且可以完全生物降解,具有一定的实用价值,可以用于垃圾袋、对卫生无要求的包装袋,农用地膜和工业用薄膜等领域。
Description
技术领域
本发明属于包装材料技术领域,具体是一种纳米氧化锌增强木薯淀粉/PBAT可降解材料。
背景技术
石油基塑料质轻价廉,并且性能良好,因此被广泛用于包装领域,但由于它们很难降解,塑料包装给人们带来效益和便利的同时,其废弃物也造成了严重的环境污染,威胁着人们的健康。因此,生物可降解的塑料和天然无毒的包装材料逐渐成为包装领域研究的热点。
淀粉是一种天然可再生的高分子化合物,来源广泛,在自然界中的储量仅次于纤维素,安全无毒且价格低廉,具有很好的生物相容性和可降解性。PBAT是一种可完全生物降解的芳香族聚酯,它是由己二酸、对苯二甲酸、1,4-丁二醇为原料通过直接酯化或酯交换法聚合而成的三元共聚酯。然而,由于PBT片段的存在,使其降解速率相对较慢,并且PBAT价格较高,限制其市场应用。纳米材料有各种优异的特性,将其运用到高分子聚合物中,可以改善聚合物的某些性能。纳米氧化锌具有无毒、价廉等优点。纳米粒子的尺寸较小,可以将分散相和材料的基体比较好地结合,使得复合材料的致密性变好,这样基材就可以在强度、刚性、韧性方面得到改善,纳米材料还可以起到提高材料防水性的作用。
但目前尚未见有利用淀粉、PBAT和纳米氧化锌为主要原料制成的可降解材料的相关报道。
发明内容
本发明的目的是提供一种纳米氧化锌增强木薯淀粉/PBAT可降解材料及其制备方法,通过采用木薯淀粉、PBAT和纳米氧化锌为成膜基质,调整添加剂和助剂的用量,使制得的可食性包装薄膜性能优异并且可生物降解,从而满足包装材料的性能要求。
