Abstract
To obtain a kind of nano-Fe3O4 with double linkage, nano-Fe3O4 particles were surface functionalized by a silane coupling agent KH-570. Then a series of waterborne acrylic magnetic pressure-sensitive adhesive (PSA) modified by nano-Fe3O4 and surface functionalized nano-Fe3O4 were prepared throughin situ polymerization, respectively. The nanoparticles and PSA were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermalgravimetry analysis (TG), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM). The experimental results showed that the waterborne acrylic pressure sensitive adhesives with good magnetic properties were successfully prepared with the addition of nano-Fe3O4, The magnetic properties of PSA were improved with the increasing of nano-Fe3O4 content. When the content of KH570-Fe3O4 was about 4% (mass), the PSA had the perfect adhesive properties. The thermal stability and adhesion properties of acrylate PSA were obviously improved by the addition of nano-Fe3O4 particles, especially by surface functionalized Fe3O4particles. Furthermore, Compared to the pure Fe3O4, the surface functionalized Fe3O4 was better dispersed in acrylate PSA while the value of saturation magnetization of PSA decreased slightly.关键词
