将季戊四醇三丙烯酸酯引入聚氨酯预聚体的末端,制备了新型可UV固化的水性聚氨酯树脂,并以其为连接料,制备了UV固化水性凹印油墨,研究了DMPA质量分数对UV固化水性聚氨酯乳液性能的影响及UV固化水性凹印油墨的性能。结果表明,随着DMPA质量分数的增加,乳液的颜色由乳白不透明逐渐转变为半透明泛蓝光,稳定性能增强,粒径不断减小,固含量随之增加,综合考虑,确定适宜的DMPA质量分数为6.25%;制得的UV固化水性凹印油墨符合国家标准的水性烟包凹印油墨的性能要求,基本能够满足实际使用过程中印刷适性的要求。

A series of newly ultraviolet curable waterborne polyurethane resins was successfully synthesized by incorporating the pentaerythritol triacrylate into its terminal chain. Then it was used as binder to prepare UV-curable waterborne gravure ink. The effects of different contents of DMPA on properties of emulsions and the printability of UVcurable waterborne gravure ink were investigated. The results suggested that with the increase in DMPA mass fraction, the color of the emulsion was gradually transformed from milky opaque to translucent with pan-blue light, and the storage stability of the emu...
