Abstract
The effect of different Zn(AA)2 content on mechanical properties of NBR was studied. The results showed that Zn(AA)2 had a great effect of reinforcement on the properties of vulcanizated NBR. SEM analyses indicated that crosslinking reaction between Zn(AA)2 and NBR might occur during the vulcanizing process, and metallic bridge bond between them was formed. With the increase of Zn(AA)2 loading, the phase state of NBR transformed from homogeneous and flat phase to netlike and parallel phase, thus greatly enhanced the mechanical properties of NBR.
