中文摘要:
      在混炼型聚氨酯（MPU）中加入受阻酚AO-80制备AO-80/MPU复合材料，并对其性能进行研究。结果表明：受阻酚AO-80与MPU的热力学相容性良好；随着受阻酚AO-80用量的增大，受阻酚AO-80/MPU复合材料的玻璃化温度逐渐向高温方向移动；与纯MPU相比，复合材料的损耗因子最大值增大，有效阻尼温域拓宽，物理性能下降，阻尼性能明显提高；当受阻酚AO-80用量为40份时，复合材料的阻尼性能和综合物理性能良好。
英文摘要:
      A hindered phenol AO-80/MPU composite was prepared by mixing hindered phenol AO-80 into millable polyurethane（MPU），and its properties were investigated.The results showed that the compatibility between hindered phenol AO-80 and MPU was good.As the addition level of hindered phenol AO-80 increased，the glass transition temperature of hindered phenol AO-80/MPU composite gradually increased.Compared with the pure MPU，the physical properties of hindered phenol AO-80/MPU composite decreased，the maximum loss factor increased，the temperature range of effective damping broadened，and the damping property was significantly improved.When the addition level of hindered phenol AO-80 was 40 phr，the damping property and comprehensive physical properties of the composite were optimized.
