摘要
采用同步法制备了聚氨酯 /环氧树脂 /丙烯酸酯三元互穿聚合物网络 (IPN) ,采用动态力学分析法研究了IPN的阻尼性能 ,以及影响材料阻尼性能的因素。研究结果表明 :三元互穿聚合物网络力学损耗因子≥ 0 .6的温度范围在 2 8~ 75℃ ;≥ 1 .4 。
PU/EP/Acrylate ternary IPN were prepared, study on the properties of IPN damping material by dynamic state mechanical analysis and the influencing factor of damping nature of the material, by simultaneous method. The result show that the mechanical loss factor tgδ≥0.6 of temperature rang: 28~75℃; tgδ≥1.4, show champion data damping properties in high temperature.
