摘　　要：PE基材使用的材料具有一定特殊性,给油墨印刷带来了较大难度,需选用附着力强、固化效果好等性能优良的UV固化油墨。在分析油墨组成的基础上,分析低聚物、多官能度单体、光引发剂给油墨性附着力、耐溶剂性等性能带来的影响,最终确定最佳油墨配方为:50%低聚物(25%PUA+25%PEA)、30%单体(15%TMPTA+15%NPGDA)6%光引发剂,制备出的油墨可在6 s内固化,附着力达到3级,耐溶剂性超100次,柔韧性达到7级,在PE基材上使用可以取得较好效果。PE substrate material has certain particularity,which brings great difficulty to ink printing.It is necessary to choose UV curable ink with strong adhesion and good curing effect.On the basis of the analysis of ink composition,carry out experiments to analyze the effects of oligomer,multi-functional monomer,photoinitiator on ink adhesion,solvent resistance and other properties,and finally determine the best ink formula:50%oligomer(25%PUA+25%PEA),30%monomer(15%TMPTA+15%NPGDA),6%photoinitiator,the prepared ink can be cured within 6 s,the adhesion reaches 3,solvent resistance over 100 times,flexibility reaches 7,can be used on PE substrate can achieve good results.
