The Study of High Heat Resistance of Nano-Modified Silicone Pressure Sensitive Adhesives

Abstract:

In this article, silicone pressure sensitive adhesives (PSAs) were modified with the Nano-SiO₂ and nano-Al₂O₃. In order to prevent agglomerate, nano powder was dealt with silane coupling agent and then mixed into PSAs, both of the processes were under the action of ultrasonic. The results of test showed that all kinds of temperature index of modified PSAs were increased obviously, which means the high heat resistance of PSAs increased evidently. At the same time, its peel strength also increased, but the tack decreased. The effects of different nano powder are different, and the decomposition temperature of the nanocomposite raised 8.32% when the content of nano-SiO₂ is 4.5wt%, while raised 14.02% when that of nano-Al2O3 is 1.5wt%, and the best compositive performances were obtained at this content of Nano-Al₂O₃.
