Description
Translated fromChinese本发明涉及印刷油墨技术领域，尤其是涉及一种水性印刷油墨及其制备方法。The invention relates to the field of printing ink technology, in particular to an aqueous printing ink and a preparation method thereof.
油墨是印刷过程中用于形成图文信息的物质，直接决定印刷品上图像的阶调、色彩、清晰度等，在印刷图文再现中起决定作用。目前市面上用于包装印刷行业的油墨以油性油墨为主。油墨以醇、酯、醚、酮、汽油等作为溶剂，对生态环境的污染性和对生产和使用工人健康的侵害性较大，同时油性油墨自身的缺点和不足，其应用的局限性日趋明显。此外，国家环保正策的施行，油性油墨的使用成本和维护成本也日趋提高，进一步限制了其应用。The ink is a substance used to form graphic information in the printing process, and directly determines the tone, color, and definition of the image on the printed matter, and plays a decisive role in the reproduction of the printed graphic. Currently, inks used in the packaging and printing industry on the market are mainly oil-based inks. Inks, alcohols, ethers, ketones, gasoline, etc. are used as solvents, which are harmful to the ecological environment and to the health of production and use workers. At the same time, the shortcomings and shortcomings of oil-based inks are becoming more and more obvious. . In addition, the implementation of the national environmental protection policy, the use cost of oil-based inks and maintenance costs are also increasing, further limiting its application.
为了解决油性油墨自身的缺点和不足，水性印刷油墨应运而生并得到快速的发展。与油性油墨相比，水性印刷油墨的环保性能更进一步。水性印刷油墨不仅不含芳香烃溶剂，而且VOC也大大减少。目前，市面上已出现可用于于BOPP、PET、PP、NY等包装基材的水性油墨，但是印品和油墨在贮存过程的干燥性、光泽度、附着力、耐抗性都有不同程度的退化，明显不能满足包装印刷业的要求。In order to solve the shortcomings and shortcomings of the oily ink itself, water-based printing inks have emerged and developed rapidly. Compared with oil-based inks, the environmental performance of water-based printing inks is even further. Aqueous printing inks are not only free of aromatic hydrocarbon solvents, but VOCs are also greatly reduced. At present, there are water-based inks that can be used in packaging substrates such as BOPP, PET, PP, NY, etc., but the printing and ink have different degrees of dryness, gloss, adhesion and resistance during storage. Degraded, obviously can not meet the requirements of the packaging and printing industry.

由表2可见，本发明的水性印刷油墨的附着力、干燥性、反粘性、遮盖力、着色力等性能与市场上的油性油墨性能相当，但在稳定性方面优于市面上的油性油墨，而最大的区别是本发明的水性油墨净味，而油性油墨则充满有毒气味，生产和环境安全难以保障。It can be seen from Table 2 that the adhesiveness, drying property, anti-sticking property, hiding power, coloring power and the like of the aqueous printing ink of the present invention are comparable to those of the oil-based ink on the market, but superior to the oily ink on the market in terms of stability. The biggest difference is the clean taste of the aqueous ink of the present invention, while the oily ink is full of toxic odor, and production and environmental safety are difficult to guarantee.
