| 中文摘要: |
| 目的 为了改善EB凹印油墨的固化性能，满足其在高速印刷设备上的应用需求，需要研究油墨固化性能的影响因素，并寻找影响规律。方法 从预聚物种类、单体种类、预聚物与单体的比例、电子束辐射剂量、电子束辐射剂量累加5个方面对EB凹印油墨的固化性能进行研究。结果 2种预聚物超支化聚酯丙烯酸酯EB150和改性环氧丙烯酸树脂6215-100可以改善油墨的固化性能;单体丙烯酰吗啉ACMO配制的油墨双键转化率高、固化速度快;双键转化率随预聚物含量的增加呈现先增加再平缓后下降的趋势，预聚物含量过多或过少都不利于油墨固化;油墨双键转化率随辐射剂量增加，呈现出先增加达到峰值后略微下降的趋势;同一辐射剂量下，累加多次可显著提高EB凹印油墨固化性能。结论 预聚物、单体和辐射剂量对油墨的固化性能都有一定的影响，掌握影响规律可以获得固化性能优异的EB凹印油墨。 |

| The work aims to study the factors affecting the curing property of ink and find the influencing rules to improve the curing property of EB gravure ink and meet its application in high-speed printing equipment. The curing properties of EB gravure ink were studied from five aspects, such as prepolymer type, monomer type, ratio of prepolymer to monomer, electron beam radiation dose and electron beam radiation dose accumulation. Two kinds of prepolymer EB150 (Hyperbranched Polyester Acrylate) and 6215-100 (Modified Epoxy Acrylic Resin) could improve the curing properties of ink. The ink prepared by ACMO (Acrylyl Morpholine) had high double bond conversion rate and fast curing speed. With the increase of prepolymer content, the double bond conversion rate increased first and then gently decreased. Too much or too little prepolymer content was not conducive to ink curing. With the increase of radiation dose, the double bond conversion rate of ink increased first, reached a peak, and then decreased slightly. Under the same radiation dose, adding multiple times could significantly improve the curing properties of EB gravure ink. Prepolymers, monomers and radiation dose all have a certain effect on the curing properties of ink. Mastering the influence law can obtain EB gravure ink with excellent curing properties. |
