目的 研究耐磨助剂（聚乙烯蜡）对无苯凹印油墨性能的影响，探讨聚乙烯蜡质量分数对墨层耐磨性能及喷涂二维码附着牢度的影响。方法 通过改变无苯凹印白墨中聚乙烯蜡用量，配制凹印白墨，并制备印刷样进行耐磨性能、二维码附着牢度等试验。结果 聚乙烯蜡可以改善墨层的耐磨性能，但其质量分数超过3%后会造成墨层与二维码附着牢度下降。当聚乙烯蜡质量分数为2%时，制备油墨印刷品的耐磨性能及与所喷UV二维码的附着牢度的综合性能最佳。结论 通过控制聚乙烯蜡质量分数可以获得墨层耐磨性与二维码附着牢度均较好的无苯凹印油墨。

The work aims to study the effects of the abrasion-proof additive (polyethylene wax) on the performances of non-benzene gravure ink and discuss the effects of the mass fraction of polyethylene wax on the wear resistance of ink film and the adhesion of QR code. The gravure white ink was prepared by changing the amount of polyethylene wax used in non-benzene gravure white ink, and the printed samples were prepared to test the wear resistance and adhesion of QR code. The results showed that the wear resistance of the ink film could be improved by polyethylene wax, while the adhesion of the ink film and QR code would decrease when the mass fraction of polyethylene wax exceeded 3%. The wear resistance of the ink prints prepared and the adhesion of UV QR code had the best overall performance when the mass fraction of polyethylene wax was 2%. The non-benzene gravure ink which has good wear resistance of ink film and QR code adhesion can be obtained by controlling the mass fraction of polyethylene wax.
