EFFECT OF AO-2246 ON DAMPING AND MECHANICAL PROPERTIES OF POLYURETHANE


Abstract:


The different ratios of AO-2246 were added to the polyurethane,and the effects on damping and mechanical properties of polyurethane were investigated. The results show that the loss factor-temperature curve of PU / AO-2246 system has only one transition peak,which is a thermodynamic compatible system; that as the amount of AO-2246 increases,the loss factor of polyurethane and the corresponding maximum temperature increase,and tanδmax can reach 1. 51;that the elongation at break of polyurethane increases when the proper amount of AO-2246 is added,but its tensile strength and hardness reduce at the same time
