摘要:采用热塑性弹性体SIS与増黏树脂松香按一定比例混合制备基胶,向基胶中加入多官能团光敏树脂,两者
混配制得紫外光固化可剥离胶。研究了热塑性弹性体与松香不同配比、光敏树脂的加入量对产品性能的影响,
并通过初粘力、180°剥离强度测试对胶体力学性能进行了测试;通过红外分析测试(FTR)、动态热机械分析
DMA以及扫描电镜SEM对其黏结/剩高性能进行了表征。结果发现,当松香与SIS二者的质量比在(0.6:1)~(1:
1)、光敏树脂与基胶有效成分两者质量比在(1.4:1)~(1.7:1)时,产品光固化前剥离强度可达6~12N25mm,
光固化后剥离强度骤降至不足1N/25mm,且被物表面无残胶

Abstract: UV strippable adhesive was obtained by adding multifunctional photosensitive resin into
adhesive prepared in prior from mixing thermoplastic elastomer STS proportionally with
viscosified resin. The effect of resin/SIS ratio and the amount of the photosensitive resin added on the
performance of the product were investigated. Mechanical properties of the products were tested by
both the initial adhesion and the 180 peel strength measurements. The bonding/stripping performance
of UV strippable adhesive was also characterized by FTIR, DMA and SEM. The experimental results
showed that when m(rosin): m(IS )was(. I(1. 1)and m(CN9013NS) m(effective constituent)
was(1.4: 1)-(1.7: 1), the peel strength of the UV strippable adhesive could reach 6-12N/25mm
and sharply dropped to less than IN/25mm before and after UV irradiation and no residue were detected
