| 目的 采用自制荧光粉一步法制备系列无苯无酮荧光凹印油墨， 并研究其性能。方法 用荧光发射光谱初步表征自制荧光粉， 并探究荧光粉含量对油墨黏度、 细度和附着牢度的影响， 研究所制油墨印刷样张的荧光性能， 筛选与市售荧光凹印油墨性能接近的配方。结果 自制荧光粉为一种稀土铽配合物， 油溶性佳、 分散性好、 亮度高； 所制油墨印刷样张在自然光下无色， 紫外中波下呈明亮绿色； 随着荧光粉含量的增加， 油墨黏度增大， 细度和附着牢度无明显变化； 附着牢度高， 耐光性和耐热性强。结论 当荧光粉质量分数为2%时， 其印刷样张最强发射峰的荧光强度与市售荧光凹印油墨最强发射峰的荧光强度相近， 配方无苯无酮符合食品包装要求， 且其细度、 黏度、 附着牢度、 耐光性和耐热性均符合国标要求， 可作为优选配方。 |
| 英文摘要: |
| A series of environment-friendly fluorescent gravure inks based on self-prepared phosphor were prepared by one-step process, and the properties of these inks were studied. Primary characterization of the phosphor was done, and the effect of the content of phosphor on the viscosity, fineness and adhesion of ink samples was explored, and the fluorescence properties of printed samples were also investigated in order to screen a formula whose properties were close to the commercial fluorescent gravure ink. The results showed that the phosphor was a kind of terbium complexes with nice performance of oil solubility, dispersibility and brightness. The printed samples were colorless under natural light, but showed bright green under ultraviolet light B. The viscosity of printed samples increased as the content of the phosphor increased, while the fineness and adhesion were not affected. All the sample inks showed high adhesion, strong heat resistance and light resistance. When the content of the phosphor was 2% , the fluorescence intensity of the strongest emission peak of printed samples was close to that of the commercial fluorescent gravure ink. In addition, the fineness, viscosity, adhesion degree, light resistance and heat resistance of the formula, without the introduction of benzene and ketone substances, matched the requirements of the national standards, thus it could be considered as the preferred formula. |
