The Dynamic Properties of Hindered Amine GW-944/Nitrile-butadiene Rubber Hybrid Damping Materials

This work was try to study the damping properties of the hindered amine GW-944/nitrile-butadiene rubber (NBR) composites. FTIR shows that hydrogen bond –CN...NH- formed between the GW-944 small molecular and the NBR matrix. The DMA results that the tanδ peak values and the damping temperature at high temperature both become larger with the GW-944 contents increasing, indicating a better damping performance of GW-944/NBR composite.
