摘 要:聚乙烯醇(PVA)作为胶黏剂,广泛地用于喷墨打印纸涂料中,而阳离子性的PVA能更好地与阴离子性的喷墨墨水结合,增强打印性能。文中利用醚化剂将聚乙烯醇阳离子化,通过正交试验法确定最佳实验条件:GTA:PVA为10:10(质量比),反应时间为2.5h,反应pH9,并将此PVA作为胶黏剂用在彩喷纸表面涂料配方中,检测涂布纸的Cobb值和喷墨打印性能,结果显示色块色密度值有明显提高。As adhesive,poly vinyl alcohol is widely used in the surface coating of color ink-jet printing paper.Due to effective binding with the anionic ink-jet ink,the cationic PVA can improve the printing performance.Poly vinyl alcohol was etherified by GTA to be cationic and the optimum reaction conditions obtained by orthogonal experimental design were as follows:n(etherification agent):n(PVA)=10:10(mass ratio),reaction time 2.5h,reaction pH 9.Then the cationic PVA was used as adhesive in coating.The results of the Cobb value and the printing performance of the coated paper show that sample color density is improved greatly.
