Description
技术领域
本发明涉及一种环保油墨，具体涉及一种增白耐久复合环保印刷油墨。
背景技术
油墨在印刷行业被大量使用，它主要是由树脂、颜料、溶剂、助剂等成分构成，目前印刷行业使用的油墨大部分是溶剂型的油墨，这类油墨会散发出对人体和环境都有危害的VOCs，有些直接与人体接触的油墨可能会对身体造成危害，有些有害物质甚至会通过包装渗透到食品、烟以及药品等包装物里，因此发展环保性油墨是今后发展的重中之重，要从根本上改善油墨的环保性，需要从改变油墨配方着手，采用新型环保材料取代传统有毒有害成分，同时获得令人满意的干燥速度、使用性能以及良好的印刷适应性。
发明内容
本发明的目的在于，提供一种增白耐久复合环保印刷油墨，为了实现上述目的，本发明采用的技术方案如下：
一种增白耐久复合环保印刷油墨，其特征在于，该油墨由以下重量份的原料制成：烷基乙基醚聚硅氧烷聚硅酮1-3、维生素E醋酸酯2-5、硫酸氢镁1-2、N-甲基吡咯烷酮0.4-0.5、丁辛醇3-5、环保白色颜料8-12、醋酸乙酯18-25、乙醇10-12、丙烯酸树脂10-15、氨基树脂12-14、助剂1-2；
所述的助剂由以下重量份的原料制成：丙二醇苯醚4-5、氧化聚乙烯蜡5-8、二甲基丙烯酸乙二醇酯2-3、去离子水15-18、十二烷基苯磺酸钠1-3、乙二醇甲醚2-3，制备方法为：先将氧化聚乙烯蜡加热至熔融状态，然后逐滴加入二甲基丙烯酸乙二醇酯，滴加过程中以800-1000转/分钟的速度不停搅拌，滴加完毕后，恒温保持20-30min备用，再将其它剩余成分与去离子水混合，待各成分完全溶解后溶液加热至沸腾，所得水相溶液再与氧化聚乙烯蜡-二甲基丙烯酸乙醇酯混合物混合搅拌制成稳定乳化液即可。
所述的一种增白耐久复合环保印刷油墨，其制备过程为：先将硫酸氢镁溶于去离子水中，配制成浓度为1-2%的水溶液，加入环保白色颜料，浸泡40-60min后过滤，将所得的白色颜料水洗至中性后干燥，处理后的颜料再与其它剩余成分混合，高速搅拌分散40-50min后，投入研磨机中研磨，至所得浆料的粒径≤10μm，即得。
本发明油墨的优点首先在于它的环保性，采用的溶剂低毒环保，不含苯、酮类溶剂，其它原料也是对人体和环境无毒或者低毒的成分；经硫酸氢镁水溶液浸泡处理后白色颜料，颜色更为鲜亮，且不易黄变，再结合有辅助干燥、加快成膜功效的助剂以及其它成分，使得本发明油墨与现有产品相比，不仅拥有优良的印刷适应性，且成膜速度快，不晶化，涂层耐热耐候，遮盖力强，使用寿命长。
具体实施方式
实施例
本实施例制备的油墨由以下重量份的原料制成：烷基乙基醚聚硅氧烷聚硅酮2、维生素E醋酸酯4、硫酸氢镁1、N-甲基吡咯烷酮0.4、丁辛醇5、环保白色颜料10、醋酸乙酯22、乙醇12、丙烯酸树脂15、氨基树脂12、助剂1。
其中助剂由以下重量份的原料制成：丙二醇苯醚5、氧化聚乙烯蜡8、二甲基丙烯酸乙二醇酯3、去离子水18、十二烷基苯磺酸钠1、乙二醇甲醚2，制备方法为：先将氧化聚乙烯蜡加热至熔融状态，然后逐滴加入二甲基丙烯酸乙二醇酯，滴加过程中以1000转/分钟的速度不停搅拌，滴加完毕后，恒温保持30min备用，再将其它剩余成分与去离子水混合，待各成分完全溶解后溶液加热至沸腾，所得水相溶液再与氧化聚乙烯蜡-二甲基丙烯酸乙醇酯混合物混合搅拌制成稳定乳化液即可。
该印刷油墨的制备过程为：先将硫酸氢镁溶于去离子水中，配制成浓度为2%的水溶液，加入环保白色颜料，浸泡60min后过滤，将所得的白色颜料水洗至中性后干燥，处理后的颜料再与其它剩余成分混合，高速搅拌分散50min后，投入研磨机中研磨，至所得浆料的粒径≤10μm，即得。
将本实施例所制得的油墨印刷在PET板上，待其完全干燥后，根据相应的国家检测标准，该油墨在基材表面的性能测试结果为：
