Popis: The damping performance of CPE/ZKF/EBP three-component hybrid consisting of two kinds of functional organic additives 2, 2′-methylene-bis-(4-methyl-6-cyclohexylphenol) (ZKF) and 2, 2′-methylene-bis-(6-tert-butyl-4-ethyl-phenol) (EBP) have been investigated by dynamic mechanical analysis (DMA). The DMA results show that a part of EBP molecules act as a bulk side group of the CPE chain in the hybrids by intermolecular hydrogen bond interaction between EBP and CPE chain, and there is a synergistic effect between ZKF and EBP on the damping properties of the three-component hybrids. When adding a small quantity of EBP into CPE/ZKF two-component system, not only the loss peak intensity of the CPE/ZKF/EBP hybrids can be further improved, but also its loss peak position can be lowered to a required temperature region. For further studying, it is found that the damping properties of the CPE/ZKF/EBP three-component hybrids mainly depend on the weight ratio of ZKF/CPE and the EBP molecules play a great role in adjusting its loss peak position. These may imply that the CPE/ZKF/EBP three-component system is more efficient in damping performance in comparison with the CPE/ZKF two-component system.
