| 摘 要： | 选用双叔丁基过氧化异丙基苯(BIPB)作为硫化剂,采用动态力学性能(DMA)测试对乙烯-醋酸乙烯酯橡胶(EVM)和三元乙丙橡胶(EPDM)共混物的阻尼性能进行了研究.结果表明,不同配比的EVM700和EPDM4640共混时,出现有"谷底"的双阻尼因子峰,不能有效拓宽阻尼温域;丙烯酸锌可以使共混物的阻尼因子峰增高和拓宽;...

| Abstract: | The damping properties of ethylene-vinyl acetate rubber(EVM)/ethylene-propylene rubber(EPDM) blends were investigated by dynamic mechanic analyzer(DMA),in which BIPB was chosen as the curing agent.The results show that EVM/EPDM blends with various ratios have two separated tanδ peaks with "valley" data,which can′t improve the damping property of blend.Zinc diacrylate(Zn(AA)2) can enlarge the tanδ peak.EVM/EPDM have two separated damping peaks with "valley" data in between 20 ℃～40 ℃ after the addition of EVM900 in blend which indicates that EVM900 can′t effectively improve the damping properties of blends.Polyvinylchloride(PVC) and EVM 700 are fully compatible so that PVC can obviously improve the damping property of EVM/EPDM blends in high temperature zone. |
