| 目的 研制一种抗菌性优良的UV油墨，提升其应用价值。方法 在超声波的辅助下，萃取香草兰豆荚的主要成分。通过FT-IR和NMR对提取物进行表征，证实提取物为香兰素，产率为18.35%，相对质量分数为33.24%。以制备的香兰素为抗菌添加剂，设计油墨配方，并研制UV抗菌油墨，测试油墨的粘度、细度、流平性、固化速率，以及干燥后墨膜的耐醇性、柔韧性、硬度和抗菌性。结果 当香兰素的质量分数为5.0%(相对于油墨总质量)时，可制备粘度为4.07 Pa.s，细度为5 μm，流平性良好、固化速率为150 m/min的UV抗菌油墨。将制备的UV抗菌油墨辊涂于集成天花板上并干燥成膜后，墨膜的耐醇性为5级，经过180°对折5次后无明显折痕，硬度为2H。抗菌性检测发现，墨膜对大肠杆菌的抑菌圈直径为21 mm，抑菌效率为99.20%，而对金黄色葡萄球菌的抑菌圈直径高达23 mm，抑菌效率也高达99.26%。结论 所研制抗菌油墨，可在保持良好印刷适性的同时，赋予油墨优良的抗菌能力。 |

| The work aims to develop a UV ink with excellent antibacterial property and enhance its application value. The main ingredients of vanilla orchid pods were extracted under the assistance of ultrasonic waves. The extracts were characterized by FT-IR and NMR to confirm that the main component was natural vanillin. Its yield was 18.35%, and its relative content was 33.24%. The prepared vanillin was used as an antibacterial agent. The ink formulation was designed and a UV antibacterial ink was developed. The viscosity, fineness, leveling, curing rate of the ink and the alcohol resistance, flexibility, hardness and antibacterial properties of the ink film after drying were tested. The results showed that when the vanillin was added in an amount of 5.0% (relative to the total mass of the ink), UV antibacterial ink with a viscosity of 4.07 Pa.s, a fineness of 5 μm, with good leveling and curing rate of 150 m/min could be fabricated. After the prepared UV antibacterial ink was roll-coated on the integrated ceiling and dried to form a film, the ink film had an alcohol resistance of level 5. It can be folded at 180° for 5 times without obvious creases, and its hardness was 2H. The antibacterial test found that ink film had an inhibition zone diameter of 21 mm and a bacteriostatic efficiency of 99.20% for Escherichia coli, and an inhibition zone diameter of 23 mm and a bacteriostatic efficiency of 99.26% for Staphylococcus aureus. The developed antibacterial ink could maintain good printability and endow the ink with excellent antibacterial ability. |
