| 目的 采用改性环境友好型涂料对牛皮纸表面进行涂布，以改善其水性油墨柔性版印刷效果。方法 采用表面涂布法，使用15 μm的线棒，以42 mm/s的速度，在牛皮纸表面均匀涂布纳米纤维素(CNC)复合壳聚糖(CTS)阴离子淀粉涂料，然后对涂布前和涂布后的牛皮纸水性油墨的印刷适性进行对比分析。结果 与未涂布牛皮纸相比，涂布后牛皮纸的平滑度提高了约28.6%，光泽度提高了近1倍，撕裂度提高了约19.3 %，耐折度提高了约15.2 %，吸水性由196.2 g/m2降至174.2 g/m2，印刷图文的密度得到显著提高，耐摩擦性较好，同时还提高了牛皮纸的抗菌性。结论 CNC−CTS阴离子淀粉涂料可以在不增加环境压力的情况下，有效提高牛皮纸的撕裂度、耐折度等力学性能，平滑度、光泽度等光学性能，以及抗水性和抗菌性，从而提高了印刷图文的印刷密度、耐摩擦性，以及印刷品的抗霉菌能力。 |

| The work aims to coat the kraft paper surface with modified environment-friendly coating agent to improve the flexible printing effect of water-based ink. With 15 μm rods, nanocellulose (CNC) and chitosan composite (CTS) anion starch coating agent was evenly coated on the kraft surface at 42 mm/s. The printing suitability of water-based ink printing on kraft paper before and after coating was compared. The results showed that the smoothness of the coated kraft paper increased by 28.6%. The gloss was nearly doubled. The resistance to tear was improved by 19.3%. The folding strength was improved by 15.2%. The water absorption was reduced from 196.2 g/m2 to 174.2 g/m2. The density of the printing pattern was apparently improved. The friction resistance was better. The antibacterial resistance of the kraft paper was also improved. CNC-CTS anion starch coating agent can effectively improve the mechanical properties of kraft paper, such as resistance to tear and folding strength, and optical properties, such as smoothness, gloss, and water resistance and antibacterial resistance, without increasing the pressure to the environment, thus improve the printing density and friction resistance of printing patterns and antibacterial resistance of printing product. |
