Synthesis and characterization of linear and crosslinked acrylic pressure sensitive adhesives for fixing battery packs in electric vehicles |
| 초록 |
The acrylic pressure sensitive adhesives (PSAs) have good adhesion properties to adhere to different substrates, which makes them a good candidate for use in electric vehicles for fixing battery packs. But it has some limitations, as general PSAs have very low glass transition temperature (Tg) and low thermal properties. To increase these properties, we adopted two techniques in this study. First, the feed composition of monomers 2-ethylhexyl acrylate and acrylic acid (AA) were changed where AA feed compositions were 5-15%. Then curing agents containing epoxy and isocyanate groups react with the carboxylic group to produce the crosslinking structure. The highest Tg and thermal properties were observed in the copolymer composition where 15% of AA and 1 wt% of epoxy curing agent were used. However, the lowest peel strength was observed for this composition because of the high crosslinking density. The characterizations were done by FT-IR, H-NMR, DSC, TGA and 180⁰ peel strength test. |
