技术领域
本发明涉及纸袋制备领域，具体地，涉及防水纸袋及其制备方法。
背景技术
众所周知，纸是一种可回收再利用的资源。造纸的原料主要是植物纤维，原料中除含有纤维素、半纤维素、木素三大主要成分外，尚有其他含量较少的组分，如树脂、灰份等。相比塑料袋，纸袋子的生产原料是树木，是一种可再生资源，同时其本身也具有的可降解、可回收利用的特点，因此受到广泛的应用。普通的纸袋防水性能差，遇水后容易开裂或破碎，使得其强度下降。
因此，提供一种防水性能优良，遇水后不易开裂或破碎的防水纸袋及其制备方法是本发明亟需解决的问题。
发明内容
本发明的目的是提供一种防水纸袋及其制备方法，解决了普通的纸袋防水性能差，遇水后容易开裂或破碎，使得其强度下降的问题。
为了实现上述目的，本发明提供了一种防水纸袋的制备方法，其中，所述制备方法包括：
(1)将树皮、玻璃纤维、硅胶、麻、稻草、石灰水、分散剂和助留剂混合并蒸煮得到纸浆；
(2)将所述纸浆经洗涤、筛选、漂白、净化和烘干得到防水纸袋；其中，相对于100重量份的树皮，所述玻璃纤维的用量为30-40重量份，所述硅胶的用量为5-15重量份，所述麻的用量为10-20重量份，所述稻草的用量为20-40重量份，所述石灰水的用量为80-150重量份，所述分散剂的用量为1-5重量份，所述助留剂的用量为1-10重量份。
本发明还提供了一种防水纸袋，所述防水纸袋由上述的制备方法制得。
通过上述技术方案，本发明提供了一种防水纸袋及其制备方法，其中，所述制备方法包括：将树皮、玻璃纤维、硅胶、麻、稻草、石灰水、分散剂和助留剂混合并蒸煮得到纸浆；将所述纸浆经洗涤、筛选、漂白、净化和烘干得到防水纸袋，通过各原料之间的协同作用使得制得的防水纸袋具备优良的防水性能，遇水后不易开裂或破碎，同时用于制备该防水纸袋的方法简单、原料易得。
本发明的其他特征和优点将在随后的具体实施方式部分予以详细说明。
