摘要

本研究以微差掃瞄量熱儀(DSC)之OIT (Oxidation Induction Time)方法，探討熱熔感壓膠添加不同種類之抗氧化劑的效能，找出適當添加配方及其含量等，由OIT實驗結果顯示以商品名1010 Tetra-[methylene--(3,5-di-tert-butyl-4-hydroxyphenyl)-propionate]methane效果較佳，但是又以複合式1010/ IRGAFOS 168 Tris(2,4-ditert-butylphenyl) phosphite混合抗氧化劑的效果會比使用單一抗氧化劑效果還好。
並以不同分子構型如線型、不對稱及星型結構的SIS（苯乙烯-異戊二烯-苯乙烯三嵌段共聚物），所製備成的熱熔感壓膠HMPSA（Hot melt pressure-sensitive adhesive），以微差掃瞄量熱儀（DSC）、熱重分析儀（TGA）、流變儀等儀器探討黏接性能、熱性質及流變行為等之關係，此研究顯示熱熔感壓膠在塗佈加工性方面可選擇添加星型結構的SIS，而若產品特性要求為保持力或耐熱性，則可選擇以線型或不對稱型之分子結構。

The study employs OIT (Oxidation Induction Time) methods of differential scanning calorimetry (DSC) to explore the performance of SIS type hot melt pressure sensitive adhesive (HMPSA) when adding various types of antioxidants to search for the proper type and appropriate dosage, etc. The results of OIT experiments show that the trade-plate 1010 (Tetra- [methylene- (3,5-di-tert-butyl-4-hydroxyphenyl) – propionate]methane) has the best effect when adding it alone . However, we find out combining 1010 with IRGAFOS168 (Tris (2,4-ditert-butylphenyl)phosphite) has better effect than using it alone.
In addition ,We employ different molecular structures of SIS (styrene -isoprene- styrene tri-block copolymers), such as linear, asymmetric and radial types to be made into HMPSA. Then, to analyse the relationships about bonding properties, thermal properties and the rheological behaviors by using DSC, thermal gravimetric analysis (TGA), and rheometer. We conclude that HMPSA increased coating workability when radial structure of SIS was used. Moreover, the linear or asymmetric structures of SIS can be considered when products require holding power or heat resistance.
