摘要
作为柔印水墨'心脏'的连结料决定着水墨的印刷性能,柔印水墨中常用的水性连结料是水溶性树脂和水稀释性树脂。水溶性树脂与水稀释性树脂的性能具有一定的互补性。科学合理地复配水溶性树脂与水稀释性树脂是保证水性油墨质量的关键。本研究对实验室自制水性树脂进行抗粘连性、再溶解性、耐湿擦性测试,并对不同用量水溶性树脂制得的薄膜柔印水墨进行印刷适性测试,以研究水溶性树脂用量对薄膜柔印水墨性能的影响。结果显示,水溶性树脂的最佳用量为5wt%。
Water-based resin,as the'heart'of flexible printing ink,determines the performance of ink.Watersoluble resin and water-reducible resin are commonly used in flexo ink.The properties of water-soluble resin and water-reducible resin have a certain complementarity.Combination of water-soluble resin and water-reducible resin scientifically and reasonably is the key to ensure the quality of flexo ink.In this paper,adhesion,resolubility,friction resistance of laboratory prepared water-based ink were tested.And printability of printing samples with different water-based resin content was tested.The effect of water-soluble resin on the performance of water-based flexible printing ink used on films was studied.The result showed that the optimum amount of water-soluble resin is 5 wt%.
