Abstract

In this study, syntheses of acrylate copolymers were performed based on the monomers butyl acrylate (BA), 2-ethylhexyl acrylate (2-EHA), and acrylic acid (AA) and the second-type unsaturated photoinitiator 4-acryloyloxybenzophenone (ABP). The structure of the obtained copolymers was confirmed via FT-IR spectroscopic analysis, and the viscosity and the content of non-volatile substances were determined. The adhesive films were then coated and cross-linked using ultraviolet radiation in the UV-C range at various doses (5-50 mJ/cm). Due to the dependence of the self-adhesive properties of the adhesive layer on the basis weight, various basis weights of the layer in the range of 30-120 g/m were tested. Finally, the self-adhesive properties were assessed: tack, peel adhesion, shear strength (cohesion) at 20 °C and 70 °C, as well as the SAFT test and shrinkage. The aim of the study was to determine the effect of the type of monomer used, the dose of ultraviolet radiation, and the basis weight on the self-adhesive and usable properties of the obtained self-adhesive tapes.

摘要

在本研究中，基于丙烯酸丁酯（BA）、丙烯酸2-乙基己酯（2-EHA）、丙烯酸（AA）单体以及第二类不饱和光引发剂4-丙烯酰氧基二苯甲酮（ABP）进行了丙烯酸酯共聚物的合成。通过傅里叶变换红外光谱分析确认了所得共聚物的结构，并测定了其粘度和非挥发性物质的含量。然后，使用紫外线在UV-C范围内以不同剂量（5 - 50 mJ/cm²）对粘合剂薄膜进行涂覆和交联。由于粘合剂层的自粘性能取决于基重，因此测试了30 - 120 g/m²范围内该层的各种基重。最后，评估了自粘性能：粘性、剥离粘附力、20℃和70℃下的剪切强度（内聚力），以及SAFT测试和收缩率。该研究的目的是确定所用单体类型、紫外线辐射剂量和基重对所得自粘胶带的自粘性能和使用性能的影响。
