摘要

本研究論文是應用於塑料板材 (如PP、PE、PET等)做裝飾材料的紫外線油墨，其為丙烯酸酯單體利用UV紫外線照射，將光引發劑產生一個活性自由基 R• 引發鏈式聚合。因其為輻射固化特性，對塑料材質的低表面熱能，且聚合速度快受到大眾喜愛大量應用各式各樣的塑料板材。但塑料材質本身的有較低的表面能，輻射固化油墨層對某些塑料材質的附著性依然是挑戰，本研究是對有困難的塑料，提出可能的解決的方案。
經實驗結果顯示，探討和提出最適化的丙烯酸酯單體和寡聚合物的配方，呈現出良好附著性的油墨，對塑料基材的3項對應是收縮、體積膨脹及表面張力等應用。1.收縮：為油墨應該儘可能以低官能基丙烯酸酯單體做粘度稀釋劑。2.體積膨脹：為油墨配方中，使用的某些丙烯酸酯單體對塑料基材的體積膨脹應該儘可能小。3.表面張力：為油墨應該儘可能適用於低表面濕潤性的塑料基材。另外，當油墨的配方固定時，輻射固化於塑料基材上，需要對每種不同等級的塑料分別做評價確認其附著性，因為各種塑膠的生產過程或處理過程，可能有不同参數的變化。每當調整塑料的表面能，可透過預先的表面處理，不僅可促進附著力，而且確保附著性的再現率。

This research paper is applies in the plastic plate (for example PP, PE, PET and so on) makes the finishing materials the ultraviolet ray printing ink, it uses the UV ultraviolet radiation for the acrylic ester monomer, has an active free radical R • initiation chain type polymerization the light initiator. Because of it for radiation curing characteristic, to plastic material quality low superficial heat energy, and the polymerization speed receives the populace to like quickly applies all kinds of plastic plate massively. But the plastic material quality's has the low surface energy, the radiation curing printing ink level is still challenges to certain plastic material quality adhesiveness, this research is to has the difficulty plastic, proposes the possible solution plan.
Demonstrated after the experimental result that discusses and proposed the most suitable acrylic ester monomer and the widowed polymer's formula, presents the good adhesiveness printing ink, to the plastic parent metal's 3 correspondences is applications and so on contraction, volume expansion and surface tension. 1. Shrinkage: Should make the viscosity diluents as far as possible for the printing ink by the low function base acrylic ester monomer. 2. Volume swelling: For the printing ink formula, the use certain acrylic ester monomer should be as far as possible small to the plastic parent metal's volume expansion. 3. Surface tension: Should be suitable as far as possible for the printing ink for the low superficial wet ability plastic parent metal. More over, when the printing ink formula is fixed, the radiation curing in the plastic parent metal, needs to each different rank plastic separately to make the appraisal to confirm its adhesiveness, because of each kind of re-vertex's production process or the treating processes, possibly has the different parameter change. Whenever adjustment plastic surface energy, permeable surface treatment in advance, not only may promote the adhesion, moreover guarantees the adhesiveness reappearance rate.
