Abstract
- A novel waterborne polyurethane-silanized CoFe2O-acrylate magnetic pressure-sensitive adhesive was prepared. With the increase of PU content, gel content, swelling capability, and SAFT increased, and fracture energy increased first, then decreased. The T-peeling strength increased from 8.93 to 19.07 N · m−1, tack force increased from No.3 to No.10, while shear resistance increased from 35 to 72 h, and then they decreased. Two empirical models: WA = 90.46 + 125.04[PU]-319.96[PU]2and T = 9.09 + 96.07[PU]-235.11[PU]2, were obtained. With the increase of CoFe2O4content, the saturation magnetization increased from 5.5 to 14.2 emu · g−1, and remanence increased from 1.7 to 3.7 emu · g−1, while coercivity decreased from 875 to 763 Oe.
