Synthesis and Characterization of High Glass Transition Temperature Acrylic Pressure Sensitive Adhesives for Battery Pack Fixation in EVs |
| 초록 |
The glass transition temperature (Tg) is an important factor in pressure sensitive adhesives (PSAs) because it is linked to a variety of adhesive properties. The glass transition temperature (Tg) of most PSAs is comparatively low, making them unsuitable for use in battery pack fixation. Three generic PSAs were synthesized in this study by adjusting the monomer feed ratio to keep the glass transition temperature below -32°C. In addition, to reduce Tg, we utilized epoxy and isocyanate crosslinkers. Because adhesion properties decreased as the glass transition temperature increased, we utilized three types of tackifiers to improve adherence. The acrylic copolymers and modified PSAs were characterized by FT-IR, H-NMR, DSC, TGA, contact angel, and 180⁰ peel strength test was conducted to determine adhesion properties. |
