【摘要】：無線射頻識別技術(shù)(Radio Frequency Identification.RFID)日漸成熟,已在商品包裝、運輸、物流追溯等領(lǐng)域廣泛應(yīng)用。目前RFID標簽的常用印制方法有蝕刻、柔版、絲網(wǎng)等,其中蝕刻印刷不環(huán)保、環(huán)境污染嚴重,柔板和絲網(wǎng)印刷制作周期長。而噴墨印刷是經(jīng)計算機控制直接將功能性墨水轉(zhuǎn)移到基材上,精度高、速度快、導電好、適用的材料廣泛等優(yōu)點。所以,將RFID標簽天線用噴墨印刷形式,噴印在承印基材上是研究的趨勢。本論文將以無顆粒型導電墨水采用噴墨印刷方式印制RFID標簽天線,探究噴墨印刷方式印制RFID標簽天線的工藝流程。主要研究內(nèi)容是對現(xiàn)有的已研制出的無顆粒墨水進行測量優(yōu)化,選出導電性優(yōu)異、穩(wěn)定性高的墨水,用IJDAS300A噴墨打印機在改性的聚對苯二甲酸乙二酯基材上噴印RFID標簽天線。針對影響標簽質(zhì)量的各因素進行系統(tǒng)的分析研究,通過正交實驗的方法印刷標簽天線,最終確定噴墨印刷RFID標簽的工藝參數(shù),并最后對噴印的標簽天線進行封裝,用于衣服吊牌上,實現(xiàn)商品在物流中追隨功能。課題通過實驗得出以下幾個方面結(jié)論:無顆粒型導電墨水加入表面活性保護劑PVP能夠有效的提高墨水的穩(wěn)定性。在20℃條件下,粘度為6.63cp,表面張力為28.1dyn/cm;通過控制電暈處理參數(shù),經(jīng)過電暈處理的聚對苯二甲酸乙二酯薄膜,提高了表面能,表面張力可增加(5-6)×10-3N/m,能夠達到52×1 10-3N/m;通過正交試驗,在IJDAS300A噴墨打印系統(tǒng)印刷標簽天線,測量天線質(zhì)量,最終確定了噴墨印刷工藝參數(shù)為:圖像分辨率300DPI,燒結(jié)溫度150℃,燒結(jié)時間20min。通過控制印刷工藝參數(shù),用噴墨印刷方法能夠噴印出優(yōu)良的RFID標簽天線,為實際生產(chǎn)提供參考和依據(jù)。
[Abstract]:Radio Frequency Identification (Radio Frequency Identification.RFID) technology has been widely used in commodity packaging, transportation, logistics traceability and so on. At present, the common printing methods of RFID label are etching, flexography, screen, etc. Among them, etching printing is not environmentally friendly, environmental pollution is serious, and the production cycle of flexo and screen printing is long. Ink jet printing is controlled by computer to transfer the functional ink directly to the substrate, which has the advantages of high accuracy, high speed, good conductivity and wide range of materials. Therefore, it is the research trend to use RFID tag antenna in inkjet printing form and jet printing on substrate. In this paper, the RFID tag antenna is printed by ink-jet printing with non-granular conductive ink, and the process of printing RFID tag antenna by inkjet printing is explored. The main research content is to measure and optimize the existing non-granular ink, select the ink with excellent conductivity and high stability, and use IJDAS300A inkjet printer to spray the RFID label antenna on the modified poly (ethylene terephthalate) base material. Based on the systematic analysis of the factors that affect the label quality, the process parameters of jet printing RFID label are determined by orthogonal experiment, and the label antenna of jet printing is encapsulated. It is used on the clothes tag to realize the function of following the goods in the logistics. The conclusions are as follows: the stability of the ink can be improved effectively by adding the surface active protectant PVP to the non-granular conductive ink. At 20 鈩，
