一种基于细菌纤维素的油墨连接料及其制备方法
摘要：
本发明公开了一种基于细菌纤维素的油墨连接料及其制备方法，该基于细菌纤维素的油墨连接料是以溶解于离子液体的细菌纤维素为基材，然后添加增塑剂和抗氧化剂改善其成膜性能，进而获得具有稳定涂层的印刷油墨用连接料。制备方法包括细菌纤维素‑乙醇溶液的制备、细菌纤维素的表面改性、细菌纤维素‑离子液体混合物的制备以及基于细菌纤维素的油墨连接料的制备等四个阶段；本发明的基于细菌纤维素的油墨连接料固化后可形成硬度达到3H、24小时吸水率低于6.0%的涂层；本发明的基于细菌纤维素的油墨连接料主体基材是天然高分子材料，其制备过程方法简单，不涉及挥发性有机物的使用，符合环保要求。
摘要（英）：

The invention discloses a bacterial cellulose based ink binder and a preparation method thereof. The bacterial cellulose based ink binder takes bacterial cellulose, dissolved in ionic liquid, as a substrate and then a plasticizer and an antioxidant are added to improve the film forming property of the bacterial cellulose, thus a binder, with a stable coating, for printing ink is obtained. The preparation method comprises four phases including preparation of a bacterial cellulose-ethanol solution, surface modification of the bacterial cellulose, preparation of a bacterial cellulose-ionic liquid mixture and preparation of the bacterial cellulose based ink binder. After the bacterial cellulose based ink binder provided by the invention is solidified, a coating with the hardness reaching 3H and the water absorption lower than 6.0 percent after 24h can be formed. The bacterial cellulose based ink binder takes a natural polymer material as a main body substrate, is simple in preparation process method, does not refer to use of a volatile organic compound and accords with the environmental requirements.
