Description

一种防水纸袋用可降解防水膜
技术领域
本发明涉及一种防水纸袋用可降解防水膜。
背景技术
目前，纸袋作为承载物被广泛使用，但是为了加强纸质材料的防水特性，一般需要在纸袋表面附着防水膜实现防水功能，传统的防水膜采用的是塑料材质，虽然有很好的防水效果，但是使用后无法和纸件一起有效降解，从而对环境造成不好的影响，一旦使用过多就会造成环境污染。
发明内容
本发明旨在提供一种防水纸袋用可降解防水膜，通过特殊配方制成的防水膜可以达到降解功能，从而实现防水纸袋的可降解性，进而保护环境。
为解决上述问题，本发明提供的一种防水纸袋用可降解防水膜采用了如下技术方案：
一种防水纸袋用可降解防水膜，包括聚丙烯、环氧树脂、酚醛树脂、黏土和硅油，其重量配比为70：8：2：16:4；原料依次混合。
进一步的，混合时加入固化剂。
进一步的，固化剂重量占比不超过1％。
进一步的，固化剂采用六亚甲基四胺。
进一步的，酚醛树脂采用热固性酚醛树脂。
进一步的，环氧树脂采用双酚A型环氧树脂。
本发明的有益效果在于：本发明提供的一种防水纸袋用可降解防水膜，通过环氧树脂和聚丙烯结合，实现防水膜的可降解性，同时利用酚醛树脂的热固性增加防水膜的强度和耐热效果，提高防水膜的适用范围。
具体实施方式
为了更清楚的了解本发明提供的技术方案，下面结合具体的实施例对本发明做进一步的说明。
本发明提供的一种防水纸袋用可降解防水膜，包括聚丙烯、环氧树脂、酚醛树脂、黏土和硅油，其重量配比为70：8：2：16:4；原料依次混合。
进一步的，混合时加入固化剂。
进一步的，固化剂重量占比不超过1％。
进一步的，固化剂采用六亚甲基四胺。
进一步的，酚醛树脂采用热固性酚醛树脂。
进一步的，环氧树脂采用双酚A型环氧树脂。
