Description
本发明适用于包装材料领域，具体是一种可降解阻燃包装材料及其制备方法。
纸盒属于纸包装的一种，它具备包装的三大功能，即保护功能、使用功能和促销功能，另外还具有加工性能好、易成型，且成型及充填工艺易于实现机械化、自动化、高速化等优点，是一种可回收、不污染环境的"绿色包装"，目前被世界各国广泛采用。
纸盒是纸板经过折叠、糊制等方法组合成型的纸制包装容器，材料多为薄纸板。由于其强度所限，纸盒的容积一般不能过大，且多应用于中小商品的外包装，如药盒、烟盒、化妆品及日用品包装等;纸盒包装的结构灵活，再加上精美的印刷，能给商品带来很高的附加值，是一种常用的销售包装。
塑料的主要成分是树脂。树脂是指尚未和各种添加剂混合的高分子化合物。树脂这一名词最初是由动植物分泌出的脂质而得名，如松香、虫胶等。树脂约占塑料总重量的40%-100%。
塑料的基本性能主要决定于树脂的本性，但添加剂也起着重要作用。对于塑料阻燃性能的研究也主要侧重于其垂直燃烧性能，燃烧时的需氧量，是阻燃性能的一个非常重要的指标。
传统包装塑料废弃后难以降解所导致的环境污染。可降解塑料是指在生产过程中加入一定量的添加剂(如淀粉、改性淀粉或其它纤维素、光敏剂、生物降解剂等)，使其稳定性下降，后较容易在自然环境中降解的塑料。
然而废弃后的纸盒虽然可以降解，但其防水性和密封性不是很好，受潮后期强度会变弱，尤其是购物袋等，存在阴雨天在外行走容易造成包装纸袋和纸盒受潮破损，而导致物品掉落。
本发明的目的在于提供一种可降解阻燃包装材料及其制备方法，以解决上述背景技术中提出的问题。为实现上述目的，本发明提供如下技术方案：

进而，在树脂组合料和纸浆组合使用后提高了纸盒包装材料在能降解的基础上进行防水，而树脂组合料中的树脂和玻璃纤维配合作用在纸浆上，实现了即使纸盒包装材料在破损进水的条件下也具有一定的抗拉强度；以及树脂组合料中的淀粉、纤维素和增塑剂进一步的提高了可降解性，而阻燃剂得加入，提高纸盒包装材料的阻燃性。
