【摘要】：隨著我國UV膠版印刷技術(shù)的發(fā)展,UV油墨因為其固化速度快,能耗低、VOC排放量為零等特點,已經(jīng)被廣泛應(yīng)用在各個印刷領(lǐng)域。結(jié)合我國印刷的實際狀況,塑料包裝印刷已經(jīng)躍居成為印刷行業(yè)的第一位。但是由于非極性塑料表面自由能較低,為了增加油墨在印品表面的附著牢度,國內(nèi)印刷企業(yè)一般采用電暈打孔等方法來增加其表面能,從而達到印刷的條件。本課題研究的目的就是解決上述問題,減少印刷工序,開發(fā)無需處理承印物表面的一系列UV膠印油墨,使其在固化時間、附著牢度等方面符合生產(chǎn)要求,用于指導生產(chǎn) 本文通過對UV膠印油墨組分中的顏料及光引發(fā)劑的波譜分析,優(yōu)化UV膠印油墨配方中顏料與光引發(fā)劑的組合以及搭配情況；以粘性、流動度、固化時間以及附著牢度為參考標準,優(yōu)選出各類丙烯酸樹脂,找出樹脂的最佳組合以及搭配情況；將各組分進行合理搭配,用三輥研磨機將油墨細度控制在15μm以下,通過正交分析實驗優(yōu)化配比,從而得到系列油墨的最佳配方。 紫外光波譜分析結(jié)果表明,光引發(fā)劑OMBB.907、EDB.ITX和369在UV膠印黑色油墨中,匹配MA-11碳黑的最佳配比為2：7：4：1：1。由于波譜屏蔽小以及吸光效率高的原因,在彩色油墨配方當中,光引發(fā)劑主要以907為主,輔助添加少量其他與顏料吸收光波沒有重合的光引發(fā)劑。 在UV膠印黑色油墨配方設(shè)計中,選用單一樹脂對油墨進行各項性能的檢測,繼而找出混合樹脂的最佳配比。通過對油墨各項性能的檢測,來檢驗設(shè)計配方的可用性。在黃、紅、藍三色油墨系列當中,實驗選取樹脂總量為65%,并且按照AK624:AK6182:7166為3：4：6的配比制備油墨。通過控制油墨固化速度、附著牢度以及在承印物表面的色密度的,設(shè)計出在樹脂配比一定條件下的光引發(fā)劑組合。
[Abstract]:With the development of UV offset printing technology in China, UV printing ink has been widely used in various printing fields because of its high curing speed, low energy consumption and zero VOC emissions. Combined with the actual situation of printing in China, plastic packaging printing has become the first in the printing industry. However, due to the low surface free energy of non-polar plastics, in order to increase the adhesion fastness of ink on the printing surface, domestic printing enterprises generally use corona drilling to increase the surface energy, so as to achieve the conditions of printing. The purpose of this research is to solve the above problems, reduce the printing process, develop a series of UV offset printing ink that do not need to deal with the substrate surface, so that the curing time, adhesion fastness and other aspects meet the production requirements. In order to optimize the combination and combination of pigment and photoinitiator in UV offset printing ink formulation by means of spectrum analysis of pigment and photoinitiator in UV offset printing ink. The curing time and adhesion fastness are used as the reference standards, and various acrylic resins are selected to find out the best combination and collocation of the resins. The ink fineness is controlled below 15 渭 m by the three-roll grinder. The optimum formula of series of ink was obtained by orthogonal analysis. The results of UV spectrum analysis showed that the optimum ratio of photoinitiator OMBB.907EDB.ITX and 369 in UV offset printing black ink matched MA-11 carbon black was 2: 7: 4: 41: 1. Because of the small spectrum shielding and high absorptivity, in the color ink formulation, the main photoinitiator is 907. In the formulation design of UV offset printing black ink, a single resin was selected to test the properties of the ink, and then the optimum proportion of the mixed resin was found out by adding a small amount of other photoinitiators which did not coincide with the absorption light wave of the pigment. Through the ink performance testing, to test the usability of the design formula. In the series of yellow, red and blue inks, the total amount of resin was 65 and the ink was prepared according to the ratio of AK624: AK6182: 7166 3:4:6. By controlling the curing speed of the ink, the fastness to the adhesion and the color density on the substrate surface, a combination of photoinitiators was designed under certain resin ratio.
