| 目的 制备性能优异的即开型彩票专用柔性版水性油墨，研究影响油墨刮开性的因素。方法 分别改变油墨配方中树脂的种类，润湿剂的种类、配比，以及乳液的种类及配比，以配制油墨，并测试油墨在隔离油上的刮开性能。探究即开票用水性油墨刮开性的影响因素。结果 选用研磨树脂Joncryl 678，油墨的刮开性能较好；润湿剂选用TEGO wet245，其质量分数为4%时，能够使油墨在正常上墨的前提下，保证较好的综合刮开性能；选用Neocryl A-1120，其质量分数为50%时，刮开层能被有效刮开，且票样老化后能够正常刮开；综合考虑各因素之间的相互作用，选择润湿剂245的质量分数为4%，乳液A-1120的质量分数为50%时，油墨的综合刮开性能最优。结论 油墨配方中的研磨树脂对油墨的刮开性有一定影响。润湿剂种类和含量对刮开墨的刮开性影响较大。其中润湿剂还影响油墨在UV光油打底样张上的上墨情况，鉴于即开票的特殊性，需对遮盖性和刮开性进行综合考量，最终合理选择和添加润湿剂。乳液在油墨配方中对墨层的刮开性起着决定性的作用。润湿剂种类与乳液种类，润湿剂含量与乳液含量间的交互作用对油墨刮开性的影响较大，在评价油墨刮开性的影响因素时，需考虑各组分的交互作用。 |

| The work aims to prepare the flexible water-based ink specially for instant ticket with excellent performance, and study the factors influencing scraping performance of the ink. The type of resin, and the types and ratios of wetting agent and emulsion in the ink formula were changed respectively to prepare the ink, and the scraping performance of the ink on the isolating oil was tested. The influencing factors of scraping performance of water-based ink for instant ticket were explored. Joncryl 678 was selected as the grinding resin, and the scraping performance of the ink was better. When the wetting agent was TEGO wet245 and its mass fraction was 4%, it could ensure better comprehensive scraping performance under the premise of normal inking. When Neocryl A-1120 was selected and its mass fraction was 50%, the scraping layer could be effectively scraped, and the ticket sample could be scraped normally after aging. Based on comprehensive consideration of the interaction of various factors, when the mass fraction of wetting agent 245 was 4% and the mass fraction of emulsion A-1120 was 50%, the comprehensive scraping performance of ink was the best. The grinding resin in the ink formula has certain influence on the scraping performance of the ink. The type and content of wetting agent have great influence on the scraping performance of scraping ink. Among them, the wetting agent also affects the ink application on the UV varnish backing sample sheet. Due to the particularity of instant ticket, it is necessary to comprehensively consider the covering property and scraping performance, and finally reasonably select and add the wetting agent. Emulsion plays a decisive role in the scraping performance of ink layer in ink formula. The interaction between the types of wetting agent and emulsion, between the contents of wetting agent and emulsion has a great influence on scraping performance of the ink. For the evaluation of the influencing factors of scraping performance, the interaction between components should be considered. |
