采用动态力学分析方法研究了氯化聚乙烯（CPE）与N，N′-二环己基-2-苯并噻唑次磺酰胺（DBS）共混制备的有机杂化阻尼材料的阻尼性能。DBS含量对阻尼行为的依赖性可分为两个特征区域。当DBS含量低于66wt%时，材料的损耗模量和损耗角正切的最大值随DBS含量的增加而线性增加，当DBS含量高于66wt%时，材料的损耗模量和损耗角正切的最大值随DBS含量的增加而非线性增加。损耗角正切的温度依赖性表明，有两个高填充的混合物的损耗峰。第一个峰较宽，tan δ约为5 × 10 - 6，而第二个峰在高温下相当尖锐，tan δ>10。通过差示扫描量热法（DSC），仅观察到高度填充的混合物的结晶峰。在DBS基体中加入少量CPE可以提高DBS的结晶度，这一发现对于新型杂化材料的开发具有重要意义。
Damping behavior of organic hybrid damping materials prepared from a mixture of chlorinated polyethylene (CPE) and N, N′-dicyclohexyl-2-benzothiazolylsulfenamide (DBS) was investigated by means of dynamic mechanical analysis. DBS content dependence on the damping behavior can be divided into two characteristic regions. At contents lower than 66wt%, the maximum value of loss modulus and loss tangent increase linearly with DBS content; however, at contents higher than that value, they become nonlinear. Temperature dependence of loss tangent shows that there are two loss peaks for the highly filled mixtures. The first peak is broad with tan δ of about 5∼10, while the second peak is rather sharp at high temperature with tan δ>10. By differential scanning calorimetry (DSC), the crystallization peak was observed only for the highly filled mixture. The finding that incorporation of a small amount of CPE into DBS matrix can improve the DBS crystallinity is very important for the development of novel hybrid materials.
