Using the dynamic mechanical analyzer ( dma ), pdms / pma ipn was investigated at temperature of 5 - 180 c. the initiator, the component ratio, the type of pdms and the filler effected the damping properties. the result showed that the damping ability varied with the parameter and there was an optimal value. the excellent damping material in the papers was ipn, where tan man was 0. 735, and the damping functional temperature ranged with tan 8 > 0. 3 was 46 c. the micro - morphology and structure of pdms / pma ipn were characterized by two kinds of sem
高分子阻尼材料的有效阻尼功能區是在ipn材料的t _ g區間內，而研究常溫條件下的阻尼性能更具有重要應用價值，運用動態熱機械分析（ dma ）儀對ipn阻尼材料進行表徵，在5 180內對其損耗因子（ tan ）進行研究，發現引發劑和交聯劑的用量、聚硅氧烷的用量和分子量等參數對ipn阻尼性能的影響較大，存在一個合理配比值，當pma與粘度為3300pa ? s的pdms之比（質量比）為1 . 17 ： 1 、交聯劑用量為1時， tan最大值為0 . 735 ，大於0 . 3的溫域差達到46 。 -
