研制了用于PE材料印刷的UV固化油墨，探讨了预聚物、活性单体、光引发剂对UV油墨的固化速度、附着力及耐溶剂性的影响，得出了油墨的最佳配方（以质量分数计）为：PUA 25%，PEA 25%，TMPTA 15%，NPGDA 15%，TPO 6%，炭黑8%，消泡剂3%，分散剂3%。按该配方配制的油墨，固化时间仅需8 s，附着力等级为3级，耐溶剂性能良好，是一种适宜于PE基材印刷的UV固化油墨。

UV curable ink used on PE materials was developed. The influence of prepolymer, monomer and photoinitiator on the UV ink properties such as curing speed, adhesion and solvent resistance were discussed. The optimum formulation of the UV curing ink was as follow: PUA is 25%, PEA is 25%, TMPTA is 15%, NPGDA is 15%, TPO is 5%, carbon soot is 12%, defoamer is 4%, and dispersant is 4%. Under this condition, the UV curing ink properties were as follow: curing time 8s, adhesion level 3 and good solvent resistance. It was concluded that the UV curing ink is suitable for printing on PE substrates.
