| Abstract: | The damping properties of ethylene vinyl-acetate copolymer(EVM) /ethylene-propylene-diene monomer(EPDM) and EVM/nitrile butadiene rubber(NBR) blends,with di(tert-butylperoxyisopropyl)benzene(BIBP) as the curing agent,were investigated by dynamic mechanic analyzer(DMA).The effects of PVC,N-cyclohexyl-2benzothiazole(CZ),and dicumyl peroxide(DCP) on the damping properties were studies.The results show that in EVM/EPDM/PVC blends,PVC and EVM700 are compatible with one tanδ peak,which improves the damping properties of EVM at higher temperature.In EVM/NBR blends,PVC and EVM/NBR blends are partially compatible with two combined tanδ peaks,which widens the effective damping temperature range to 62.4 ℃.1.4 phr DCP enlargs the tanδ peak of EVM/NBR with the effective damping temperature range up to 64.9 ℃.Small amount of CZ can enlarge the tanδ peak of EVM/NBR.5 phr Zn(AA)2 can also widened the tanδ peak of EVM/NBR. |
