【摘要】 本论文主要研制水性近红外吸收喷墨油墨和分析其防伪性能。水性近红外吸收喷墨油墨主要是由去离子水、红外吸收染料、溶剂、树脂和助剂等物质组成,其中染料是决定油墨防伪效果的重要组成成分,并且染料对红外光的吸收强度及各项物理性能有很大影响。利用配方设计原理制备了综合性能良好的水性近红外喷墨油墨,并用爱普生K100喷墨印刷机打印印刷样张,用FDD-500(中标方圆防伪技术有限公司)测试油墨防伪效果。实验结果表明,溶剂对近红外吸收喷墨油墨染料的溶解性和表面张力等方面的性能有影响,树脂是决定体系黏度的关键因素,红外吸收染料的含量直接影响红外吸收强度的大小。本实验所研制的油墨具备良好的喷墨性能和防伪效果。更多还原

【Abstract】 This thesis mainly studied the preparation of water-based near infrared absorption ink jet ink and analyzed anti-false property.Near-infrared absorption ink jet ink is composed of infrared dyes,solvents,resins and additives and so on,the dye was an important component which decided the security effect of ink,and the dyes had a great impact on the properties of infrared absorption intensity and the physical properties.The water-based near infrared ink jet ink sample with good comprehensive performance has been prepared,and the properties of the ink were adjusted according to the ink jet printer which was used in this experiment.FDD-500(Fang yuan anti-counterfeiting technology Co.Ltd.) was used to test the effect of anti-false.Experiments results showed that solvent has a great effect on the solubility and surface tension of near infrared absorbing ink jet ink,resin was a key factor determining the viscosity of the system,and the content of infrared dyes directly affected the infrared absorption intensity.The prepared water-based near infrared absorption ink jet ink sample has the good performance and anti-false effect.更多还原
