The CPE/ZKF/EBP hybrid damping material of embodiment 1～embodiment 4 prepared multi-component hybridization high-performance vibration reduction composite materials and simple chlorinatedpolyethylene (CPE) and different ZKF, EBP mass percent, estimate with the peak value of dissipation factor tan δ and the temperature position of loss peak correspondence by dynamic mechanics heat analysis instrument (DMA) test, its contrast test result distinguishes as shown in Table 1:
Table one CPE/ZKF/EBP hybrid material
| ? | Body material CPE | CPE/ZKF60/40 | Embodiment 160/35/5 | Embodiment 260/30/10 | Embodiment 360/25/15 | Embodiment 460/20/20 |
| Dissipation factor tan δ peak value | 0.772 | 1.569 | 1.685 | 1.859 | 1.844 | 1.65 |
| Tan δ peak position (℃) | -9 | 40 | 36 | 34 | 31 | 26.5 |
From table one as can be seen, in the CPE/ZKF/EBP hybrid material, under the condition that the mass percent of body material CPE remains unchanged, adjust the mass percent of ZKF and EBP, increase along with EBP content, low-temperature region obviously is partial in the position of the loss peak of CPE/ZKF/EBP hybrid material, and when ZKF/EBP content was 20/20, the position of loss peak had dropped to 26.5 ℃ from 40 ℃ (ZKF is the position of the CPE/ZKF loss peak of 40wt%); And the height of loss peak improves along with the increase elder generation of EBP, and the back descends.The value of loss peak has reached 1.859 and 1.844 respectively when ZKF/EBP content is 30/10 and 25/15, has higher damping vibration attenuation performance; When ZKF/EBP content was 20/20, the value of loss peak was 1.65, descended to some extent.This phenomenon mainly is owing to exist ZKF and EBP the time, has played synergy, at EBP content more after a little while since EBP with the form of macromole side group by the hydrogen bond grafting on the molecular chain of CPE, increased the free volume and the flexibility of hybrid material on the one hand; On the other hand, when being subjected to outer field action, since the fracture of hydrogen bond between EBP and the macromolecular fricting movement of CPE and EBP and the CPE macromole, certain mechanical energy that dissipated, thus loss peak is increased to some extent.When the EBP amount surpasses threshold value,, also reduced the anti-plastification of ZKF simultaneously, thereby caused the decline of CPE/ZKF/EBP hybrid material loss peak height because the increase of hybrid material free volume has reduced fricting movement between the macromolecular chain.Therefore, EBP has played plastification in the CPE/ZKF/EBP hybrid material, thereby reach the position of adjusting hybrid material vibrating absorption peak, the hybrid material damping vibration attenuation performance of having gone forward side by side one-step optimization makes material be issued to satisfied effectiveness in vibration suppression in different use temperatures.
