摘　　要：以典型的某牌号粘弹性阻尼材料为研究对象,分别在三亚试验站的全浸和仓储不同试验区带进行了长期自然海洋环境曝露试验,并对获得的老化周期为5年的试样进行了微观结构、力学、动态力学以及减振效果的测试和表征,并分析了海水介质对粘弹性阻尼材料老化性能影响的机制。The long term marine environment outdoor exposure experiment on the typical ship polymer damping materials under storage and seawater immersing test conditions was carried out in the South China Sea.The SEM characterization of the microstructures,mechanical properties,dynamic mechanical properties,glass transition temperatures,cross-link density,and the anti-vibration effect of the samples aged for 5 years were researched.The test results were analyzed to research the effects of the seawater on ageing process and properties of the ship viscoelastic polymer damping materials.It could be seen that the effect of pervasion and swelling of seawater on the properties of the ship polymer damping materials was notable and non-ignorable.
